We have a robot placing pins on a flat glass surface. Then the product get autoclaved, then ground and then other attachments are added via urethane glue. We have an issue that we think the robots are not capable, and we want to add a vision/scaning/camera/laser system that will check the 4 pins to the math data to positions and tolerance. If the part is rejected, we need a signal and a robot will pickup the part and set it aside. We have a 2nd area we also want to do a similar check, since the part goes through a heating cycle. We want to make sure that the pin position did not change and are still go to the math. All this must be automated and data for each part must be stored for SPC work. Need help with coming up with a system in line conveyor to improve quality.
The real key here is the fact that you are inspecting glass. There are a number of techniques to improve contrast of glass. Also the tolerances of how well you are trying to position these pins. Could you send a sample so we could take a look and suggest a method for doing this, if so please contact me at the email or phone number below.
Hello experts, I am looking for a vision system capable of capturing very small particles in a liquid. Where do I begin?
So the challenge with your question is there are a number of ways that this can go without putting some bounds around it. I would suggest you determine how big an area you need to look at (height and width) to determine where the small particles are or how big they are. Also what depth of liquid are you looking at? Will you being looking in a bottle, or a glass fish tank type environment? Are the particles visible if a human were to look at them? All the answers to these questions and Ivan's will help others be able to answer further questions.
Hello, I'm looking for fiber-optic components and to capture microscopic images (in a relatively controlled environment). The feature resolution would be as small as 10-20 microns. Any pointers would be appreciated.
Andy, There is a bit more information needed to determine your needs, but I thought I would ask some questions to maybe help generate some thoughts. Are you looking at the surface in 2D or 3D, do you only care about the visual appearance, or do you want to know what the surface is doing in 3D space. When you talk about 10 - 20 microns is this the size of a defect or surface finish feature, or is this the area that you care to look at (otherwise known as Field of View)? The size of the smallest thing that you want to be able to see generally inversely drives the cost of a system, or increases the inspection time. It is important to know the smallest thing you want to see, as everything else is a function of this. Please feel free to share more information either on this forum, or send me an email. Andy
We will capture from 11 USB3 cameras (1920 x 1200, 1 byte per pixel) at 100 frames per second. Capture into a single PC ideally. With our own software to process, store and analyse the data. Video data is initially stored in memory, not streamed to disk. This requires a multi port USB expansion solution, probably based on PCI express. We need full USB 3 bandwidth per port. Hence this card appears well suited. Also, I believe the manufacturer offers a 16-port option using 2 DU3X2-IPCIE2XG201 with the one PCIe board (IP8X-PCIE8XG201). That would suit us even better. Is this available? Prices for all would be great.
Michael, I was at Automate 2017 a few weeks ago, and I saw cameras that connect to the PCIe bus directly, this might be another option for you. I don't know if this is the only company, but here is a company name that might help you (Ximea). best of luck. Andy
Hi, I'm working on a tool inspection microscope setup that looks at an edge about .3 mm in radius. fps isn't a big deal, but I'd like to have a very clear image of this edge using a usb camera and an appropriate lens setup. Has anyone ever done this kind of thing before?
Evan, A large percentage of us have done this type of thing before. I would encourage you to figure out the following items: - field of view - how large an area do you need to look at? - what is the smallest thing you need to be able to see. For example if you would like to see a 0.3mm radius, and you want to see how smooth that radius is, then would you want to see 10, 20 or 100 pixels around that radius. The camera is digitizing the image, so you have to figure out what you can accept when you zoom in on it. Are you looking for problems on the radius that are 1/10 of the radius for example. Can you move the field of view as you work, just like a microscope? Does the radius have a 3d component to it too? Are you already using a microscope? If so why not just plug in a microscope camera? Are you undertaking automated measurements? Please feel free to drop me an email or give me a call, and I'll try and point you in the right direction. Andy
We have a machine which moves forward in a high speed with 5 and 5 bottles in each row. There are about 3,3 seconds between row-shift and I wonder if you have a camera system that can be used or can be modified to suit this kind of inspection?
Torstein, What kind of inspection are you doing? If you are just looking to make sure the bottles are in place you can probably use a smart camera to do that.If you're not sure of the term smart camera, do a google search but basically this is a camera that has the processing on board. Typically you would program the solution using a point and click interface and download it to the camera after which the camera runs stand alone, and will typically run without any user interaction. If you are trying to do more complex inspection, then you might need more hardware/experience. I would do a search on google for smart camera and try and speak to some smart camera manufacturers, who may be able to point you in the right direction, may even be able to demo at your facility. Need any further help, feel free to drop me an email. Andy
I have 6 aia AD-080 GE Camera a miried of cables, shutter driver, wagos , synquinet plc, ssystec electronics sysworxx CANopen, and a large amount of other imaging related hardware and software I acquired at a industrial auction. I am interested in setting up a inspection system to view coin and paper currency for the purpose of documentinting and grading the items. I have a degree in automation but without the accompanying wire diagrams I do not k ow what would be required for a simple stationart manual imaging table. How can i find out what works best with these cameras ie wago vs synquinet etc? Do you have any simple drawings or materials involving simple instalations avaable for the public?
Its difficult to describe what you can do in terms of using equipment that you got during auction, typically the problem defines the types of equipment and specifications of this equipment, but if you want to investigate for academic purposes what can be done with the equipment you have I would do the following: Look at the AIA youtube channel for the training material that will help you pull out the equipment that can help you. Looking through these video's will allow you to get an understanding of why equipment is chosen, and when choosing the right equipment you have more chance of the system being a success. https://youtu.be/Mf5W3M-oirQ - Here is the first video, i would pay particular attention to the lighting that you need for your purposes. Good luck, you may find you have some items that are the correct pieces, but I would be prepared to purchase some others to save you wasted time. Andy
Hi, does anyone here have experience with imaging LSR (Liquid Silicon Rubber)? In our application we are over molding a polycarbonate insert with LSR . We need to detect LSR flash on the polycarbonate insert that can be less that .001in thick. We have three different colors of polycarbonate, but, I am currently working with orange. The LSR is translucent. I am currently unable to differentiate between the LSR and polycarbonate.
Nicholas, Have you looked at the LSR with a hyperspectral camera. This might give you one or more regions of the spectrum where the signal is different than with purely visible light. Also try and determine if you hit the LSR with certain light if it emits light at a different frequency. Some of the plastics perform well with these techniques, but you usually have to experiment to get the results. Andy
I am doing a simple tape and shake mold inspection. The molds are ceramic. I cover the opening with blue tape. I shake the mold and if there is a defect, white flakes fall out and stick to the tape. there is significant contrast between the white flakes and blue tape. is there a system that could count the number of flakes. That could measure the size of the flakes and give me a distribution of flakes per size brackets?
John, is there a reason that you don't inspect the mold directly instead of going through the process that you currently do. There is technology such as 3d scanning that can inspect the surface directly. If you want to look at masking tape, try and get consistency in terms of how you present that to the camera. If you want to discuss more please feel free to call me at 888-508-7355. Andy
which is the best camera for an online egg sorter?
Saeedeh, For you to determine the specifications for an egg sorter, you need to be able to define the difference in the egg classification - for example, if you are only sorting by color, get the lowest resolution camera, and only process the central are of the egg to determine color. If you are trying to grade the eggs by size, then you will need to get the camera that has enough pixels (you'll need between 5-10 pixels) to show the difference between the 2 nearest eggs you are trying to classify. A camera lens combination with a FOV that represents your largest egg would be your best solution. Good luck with the project, just try and ensure you break the problem completely before you start.
Looking for photo imaging for manufacturing parts in the forging industry.
Karen, These are the kinds of questions you are going to be asked. How big are the castings? What is the smallest defect that you want to see? Are there 3D issues that you will be looking at? What kind of environment is this - pretty dirty I'm presuming. How will you reject defects? What is the criticality of a false defect? What is the cycle time for the inspection? How much are the castings worth? These are typical questions that you will asked from a company wanting to help you. Can you provide us with samples - we can run them through our vision lab, and show you results without any investment on your part.
Good afternoon, I came across your website online and wanted to inquire about some products. I am looking for a solution that I can use in a manufacturing facility to mount to a piece of equipment in order to receive a command, take a decent resolution photograph, create a file which will be linked to an order and fed back into our system for later review, filing etc. The solution would need to use Ethernet for connection to our system. Could you please let me know if you have something in your product portfolio that may fit the above bill? I am looking at making a purchase within the next month or so and would need to outfit roughly 48 machines worldwide. I can be reached at the below numbers. Thank you in advance and Regards
Kristen, Are you looking for components or a complete solution. We are a Machine Vision Integrator, and would be willing to create a bolt on solution for you if that is the route you want to go down. The following questions will need to be answered to allow camera selection: 1. Field of View - the total area that the camera will be looking at, at the depth away from the camera that the object(s) are. 2. The smallest item that you want to be able to make out. 3. You also need to consider working distance - distance from the camera to the objects that you are viewing. There are numerous other items that need to be discussed like lighting and line speeds? etc. Good Luck, if you want any further information, please feel free to contact me.
We are using a Yag laser welding a 1mm dia seam to retain a plug pressed into a hole. We have a camera mounted looking thru the laser focus lens. The camera is used for aiming the laser before cycling. Can we integrate an automated vision system which checks the weld for holes after welding and then signals the controller to mark either good or bad welds? Thanks, Dan
Dan, Are you interested in looking at 3D weld information or 2D information. It would help me if you could send some images with a good and a bad weld identified. Feel free to send some image to my email address. Andy
Hello everyone: I would like your suggestion about which kind of cameras, FPS/Mono/Color to use for 24/7/12/365 day and night. The cameras will be mounted on a 70 feet roof cover. The control room will stay 100 Mts away. The vision system should be capable of counting all trucks parking on a trucking yard.
Udo, There are many techniques for tracking vehicles like these. Are you sure you want a camera solution? How are you going to process the images? Are you going to do that, or are you more interested in a complete solution. Please contact me, so we can discuss in more detail. Andy
CMOS cameras are becoming more available. Are there any test standards that can be used to compare the performance between cameras?
Frank, There are a number of ways to measure performance, but just as with anything there are multiple components to the system, including light/optics and camera itself. If you are trying to compare camera performance for a specific job, the best way is to control everything else, and then change out the camera, if this is possible for your scenario. There is a number of websites that have great videos for showing how to do these kinds of tests, but they may be looking at one of the other components. http://www.edmundoptics.com/technical-support/technical-library/videos/ The bottom line is you can use the same test, and control a number of variables to test your camera. If you want to know which camera is best before purchasing, then you are going to have some difficulty, as there is a challenge in the way different manufacturers present there information. Please also don't forget the other components or you will pay the price. The easiest way is to test for application.
We have a spiral blast freezer in our plant. It runs at -25 to -30 deg F. What can be used to detect product that falls off in the event of a jam on the line?
Geno, There are a number of techniques that could be used to solve your problem. Would you be able to supply photographs, so we can give a more detailed answer. IR cameras are able to see temperature differences, and this might be one way to look for products being where they shouldn't. Or it could be a view of the line when clean versus when objects have fallen where they shouldn't be. Give me a call to discuss, or send me an email with pictures, and we'll see if we can help guide you down the right path.
I am looking to learn about Contrast Transfer Function (CTF) and measuring a camera's resolution. Can you suggest any papers to read, books to read, or web sites to visit?
Take a look at this video from the AIA. This is part of the AIA Certified Vision Professional Training. Andy
What would be a cost-effective setup to sense a soccer ball's accuracy and speed? We are building a soccer simulation lab in Northern VA and would like to speak with someone about this engineering challenge as we fit the facility.
Sounds like an interesting project. There are a number of items that you need to consider, and you need to find out which parameter is going to be you're limiting factor. My details are attached. Send me an email, and we can arrange a call to discuss in the new year.
Would appreciate tips and proposals for solving the following application: I would like to build a system that is able to identify random (X, Y) coordinates with an accuracy of ca. 0.5 mm of a small amount (less than 24) of solid pins on a plane. The pins hit the plane randomly and consecutively one by one. They can be a bit tilted, so the position of the pin cannot be determined from the far end, but rather from the point where it is attached to the plane. The pins are made of carbon fibre or aluminum
Timo, There are a number of questions that we would need to ask, what would the total field of view be (x by y), and the size of the pin (radius?). These would all help in being able to determine the accuracy of finding the pins. Please feel free to forward me some further information, or supply a sample to us, and we will explain what we do with your sample to get results from our machine vision lab. We typically will undertake a small vision study to show you the technology that you will need to solve your problem.
I am using Pleora's GigE Vision Imperx BobCat GEV camera and I am saving images in raw data format. How can I convert these to a jpeg? Also, is there a way to convert these images in a a batch?
There are a large number of software programs on-line to convert between image types. I would just make sure that you know what you want, if you are converting to jpeg, just for users to view then this will work for you, but if you want to analyze them with software, then you need a bmp or png format, to make sure you don't loose data from the original image.
We produce in our company, Behran Toos which is located on Iran, different parts of filters such as different parts of car oil filter. We are looking for a system based on camera to control the flaws of our canister (filter housing).
We produce a system that can detect flaws without any programming. If you would like to try it, send me an email, and we'll let you try it out, see what kind of success you will get.
I have an older vision system on a process that is working well. The concern is obsolescence. The system uses a Coreco PCVision PCI card in an NT based PC. I would like to set up a back up system, hopefully using newer OS such as XP. Would like to find contacts who had experience with these and could enlighten me during my upgrade backup journey. The vendor that supplied the system no longer supports it and no longer has the knowledge of these systems. Thank you in advance
Perry, This seems like a traditional challenge with today's technologies, not just with machine vision, but with all test and manufacturing systems. Just out of interest, how long has the system served you? We are a machine vision integrator and create systems like these, but I'm assuming your biggest challenge right now is even if you are able to replace the hardware how would you verify it. Do you have all the documentation for how the system works etc, how it was validated etc.? If you need any further help please don't hesitate to get in touch. Good Luck.
I need a small system to project and detect: I need to project our company logo and detect if anyone steps on the logo. In other words, I'm looking for an integrator that can specify a system that can detect movement across a 3 foot diameter circle located about 7 feet away.
Josh, We can supply a system like this, it would help to discuss a few further details. Please feel free to contact me at your leisure. Andy
I am an online bookseller and currently we sort about 1 million books a month using a non automatic process with reps. scanning a bar code. We'd like to find a company that can build a sorting system using cameras and high speed conveyors. Do you know of a member(s) that might might be able to help?
Mark, I wanted to ask a few questions for the forum, so that it can hep us guide you and also help others in the future visiting these pages. Are you planning on the books barcodes being visible on the conveyors, or do you want the visual of the book to be the identifier. The reason I ask is that a barcode is designed to identify a unique object, but only a few barcodes are designed to be read at high speed/obscure angles, and these are the barcodes you typically see on the side of FedEx or Amazon type boxes, where the visual appeal of the box doesn't matter. If you are trying to identify the book (without barcode), then you need a completely different appraoch. You might want to use OCR (Optical Character Recognition) to identify title and/or author and then do a fast database lookup to see if this is a potential, and then maybe match against an image of the book. Feel free to contact me, if you would like any further information.
I need assistance in the research and development of a lens/reflector/bulb assm. for a replacement application in my industry.
Lance, We are a machine vision system integrator, please feel free to call me at your convenience to discuss.
What would be the best lighting solution for inspecting glass parts within a polycarbonate plastic enclosure?
Kyle, As Perry hinted at this could be a challenging issue depending on the two surfaces you are looking at, If you have samples you are willing to share, we can undertake a vision study and see if we can get any results that would be usable in a system. Andy
Is there any system that can scan (or see) an irregular depression (a sand casting for example) and be able to calculate the volume of material required to fill it? Thank you.
Mark, You can use laser triangulation 3D vision systems to measure volume. These are basically a line of laser and a camera moving across an irregular surface will give a number of profiles across the surface. If you want to know more send me an email address and I'll be able to send you some images of what I'm talking about which may help you. Best of luck.
I am looking for a camera enclosure. I have been currently using a Vizient camera enclosure that is designed for welding applications. I need something that is sealed and water tight so that when the enclosure is mounted on the EOAT of my robot and I am entering a machine tool that is dripping coolant all over my camera doesn't get wet and the lens has a cover to protect from any coolant getting on it as well.
Steven, What is the camera you are using, I might be able to suggest something for this.
How do I place parts to be inspected into an indexing wheel?
Bill, I might have an answer for you with regards to some technology that isn't released yet, but the company is looking for pilotplants for the technology. I will say though it is targeted at your specific problem. If you're interested send me an email with your contact info, and we can talk off line. Andy
Good day, I'm looking for a list of companies able to supply a vision system able to detect on line the presence or absence of an expiry date printed with an ink jet printer. The system should also be able to detect the conformity of the printing (missing dots, distorted dots / character, stained, wrong typo). Can you help me ? Best regards, Olivier
Olivier, What I would suggest is that you send some samples, and that way we can give you a vision study to inform you how successful the results are likely to be. Please email me at the email below to discuss more. Andy
I would like to see what is available to measure closures and I am looking to upgrade with AVID; we wanted to see if there was any new technology before we buy the AVID.
Barb, I would like to ask you a number of questions, such as why you are looking for a different system, but I feel that maybe there is too much information to be typed into this forum, but I do believe it would be beneficial to all if you could spend the time. There are literally thousands of different options when it comes to selecting vision, and as a member of the community, I would be very interested in hearing what drives you to your decisions. One way to see a lot of the technology that is available today is to visit the Vision Show in Boston the week after next. This literally happens every 2 years in the USA, and it seems like its perfect timing for your needs. You will see technology that you probably weren't aware of, and it will allow you to make comparisons with your current vendor, but either way it will show you what is possible today. I have included a link to the show here (http://www.visiononline.org/events/event.cfm?id=117). Bring your parts!
Can you provide contacts at companies that are experienced replacing humans performing magnetic particle inspections by automatically segregating defective (cracked) parts from parts without defects? This process is performed on heat treated steel forgings.
Henry, I'm not sure exactly what you're looking for from your description, but it sounds like you are after a machine vision inspection system that can detect cracks on components, whilst they are being manufactured, or on the vehicle? Send me an email if you like to talk more on this issue.
My company BuySend.com is a huge online retailer in the UK, we have over 500,000 products in our catalogue. When dealing with new suppliers we request a spread sheet of the suppliers’ entire product inventory, including the product barcode. We upload these products into our system, before adding further details and listing the product for sale on our website. We now have a major issue where sometimes the suppliers spread sheets do not include the leading zero on barcodes (sometimes due to the format they have been saved in), or sometimes because they are a UPC barcode and have less digits. We want to know if there is some sort of barcode validation tool we can use in our system, so that if for example we try uploading the barcode 77540050857, our system knows that the actual barcode should be 077540050857 (with the leading zero). It would therefore not create a duplicate product in our system like it does now. It would also be ideal if it could spot bad barcodes and simply not import them into our system as new products. I am sure every single large retail company comes across this issue and as you are probably aware we simply cannot afford to have bad data in our system, especially when it comes down to barcodes, as this causes havoc across many areas of our company. Please let me know if you offer some of service that would be able to aid us with this? If not, do you know any companies that would be able to help?
Paul, It seems like this is not a machine vision issue per se. But you just need to know your suppliers format. Obviously there is nothing that says a barcode needs to be one length or another, so it is not possible to sort out the "correct" barcode without figuring out some rules that might apply. Send me an email, and we can set up a phone call. This could be something that is done very quickly depending on figuring out the rules that your supplier might use.
I'm looking to inspect flat sheet metal patterns. Ideally i want to take a picture with the sheet metal pattern on a light table, a software to detect the edges then compare this with a dxf or 2D electronic drawing of the part, complete with GD&T. Are there off the shelf solutions for this, or software which imports pictures and gives the user the ability to generate a report for the part?
Nasir, We have a solution similar to this that could be tuned for your purpose. We have a tool scan inspection system, where tools are scanned on a light table, and then CAD data is produced for cutting the foam that tools are placed in inside the tool boxes. If you would like to discuss further, please give me a call, my info is below.
Hello. I am interested in the minimum requirements for tracking humans walking out of a store in a shopping mall. I would like to be able to determine the number of shoppers that walk out of my stores with a shopping bag in hand. This is industry research data I am trying to gather from a retail environment where many people may be walking in view of the camera. Specifically I would like to know the number of people that walk in to my store, out of my store, and the presence of a clothing store shopping bag in hand. Ideally a small standalone camera could either do all processing or provide video data for off-site analysis. Solution should be small and require only a network connection to provide video out or a the various people counts we desire. Solutions are also ideally under $200 for the camera-location installed component. A small systems board nearby or integrated with the camera system would also be suitable. WiFi transmission of data out is also ideal.
Cyrus, The cost constraints seem to be quite tight, but I was wondering what volume of systems you are looking at? This obviously has an effect on these types of systems.
I am researching the possibility of using vision sensors (camera/laser) to scan components which are worn out, comparing the acquired image to a CAD image of the part as it should be, and then using robotics to weld/clad the missing areas to original dimension. Are there any existing off-the-shelf products that do this? Any contact with experts in this area would be appreciated. This is obviously going to require integration between image acquisition, CAD software and welding automation and robotics.
Jason, We specialise in 3D scanning technologies, and Robotic Integration. We are an integrator based out of California, but you're list of wants matches our abilities to deliver. I'm going to suggest the following, we like to get a sample before any engagement occurs, to be sure that we are able to perform. We would then run this through our machine vision lab, and then rather than do a fancy proposal, we'll show you what you get with 3D images of your scanned part, and if you send a CAD drawing too, we'll show you the comparison. Please contact me if you're interested. Andy
I'm looking for a vision system solution in conjuction with Liquid Penetrant Inspection (LPI) also known as Fluorescent dye Penetrant Inspection. The system concept is to visually inspect parts that have been prepared and subjected to UV lighting. The system is to accept or reject conforming and non-conforming parts by identifying cracks. The penetrant dye remains in the cracks and "glows" under UV light.
Serge, The only question I have is do you have an old failed part, and some dye, and the dye characteristics. We could run a sample at our machine vision lab, and show you the kinds of results you are going to see. Please feel free to call or email, and we'll see if we can help you.
We are going to built a hi res (cca 16MP) full body color scanner with synchronized multiple camera setup. We'll be using a photogrammetric SW (eg Agisoft ) for stitching photographs into a 3D model. Will be used for a biometric and 3D printing purposes. One option is to buy cca 25+ DSLR cameras but I am affraid of "getting lost in cables". Is there any option in MV field, ideally within $100K budget?
Ludvik, Please give me a call to discuss, we might be able to give you some pointers to get you going in the right direction. There are a number of options available to you. Andy
We are using the Cognex In-Sight 5604 linescan camera with RED ring light mounted on front of the camera lens. And the target object is rotating on the shaft with encoder. We are trying to confirm the linescan camera algnment with light and target object. But I don't know the best way to confirm alignment. Can someone provide some tips or instruction?
Sunho, Please feel free to post further information or call to discuss your specific problem. Calibration and alignment of camera systems can be one of the large burdens that continue to plague some systems in the field. Getting this right is the key to your system going forward. It will be worth the time of you documenting exactly what you want to 'calibrate' or 'align' to. This forum is designed to help you get information about machine vision in general, so please feel free to post more information or call. Andy
I am looking for equipment and expertise to track the position of a .2 mm dia fluorescent particle in clear fluid contained in a dark 150 mm cubic volume. Will want hardware with software and integrator to interface with display to show track of particle.
Clark, This looks like quite an exciting project. We have done similar things in the past. There are a number of questions that you will need to answer and I'll list some of them here to allow others in a similar position to be able to look it up. - What frequency of light are you suing to stimulate the particle? - What frequency of light does the particle fluoresce at? I'm assuming a Stoke's shift. - Does the whole 0.2mm diameter particle fluoresce.? - Are you interested in measuring the particle in x,y and z? - How fast does the particle move? - What is the material of the box? Hope these questions help? Feel free to give me a call or email with additional questions. A.
I need an inline vision/scaning/laser or other system to check pin locations/tolerances that are applied by robot in production.
Mike, I'm assuming that some of these pins or where the pins are located involve glass. the challenge with glass is getting the right lighting setup so that you can create contrast of the positions you are trying to measure, so that there is a difference between what is good and what is not. Would you be able to send samples to our vision lab, to see if we can help you? Andy
Hello. I want to implement a camera which supports GigE Vision on a mobile robot. The robot main control is reachable in the company intranet via W-Lan and has an ip-address of the address range 12.12.XXX.XXX. The main control of the robot works as a router and builds an own subnet for the components on the mobile robot. The camera is integrated in this subnet. The subnet uses the address range 192.168.XXX.XXX. Is it possible to reach the camera in the subnet by a workstation in the company intranet? We have already implemented the portforwarding for GigE Vision in the robot control which forwards the request from a workstation in the company intranet to the camera in the robot subnet. But it isn’t possible to find the camera with GigE Vision Tools from the intranet. The main question is: Does GigE Vision support network routing? Thank you for your efforts.
There are a few challenges with GigE vision cameras on networks. The first thing I would try is to install the camera manufacturers software (that is the actual manufacturer of the camera usually have some software for configuration), and see if you can find the camera from this, as this typically uses MAC address searches for the equipment. Hopefully this will help you.
I am looking for recommendations for someone who has implemented vision solutions in wood fabrication industry (cabinets/Doors/furniture)...exploring in line applications for color match, gaps and flushness checks
Bhavan, We use a combination of traditional and deep learning machine vision techniques that i believe could help you. Please send us some samples or parts, and we will undertake a vision study to be able to see what is possible for your products.
I am looking for defect identification software in carbon steel piping. The images would be recorded on a SD card in a video camera. The camera is moved through the pipe via pressure and will travel up to 25 kms. We need the software to stabilize the video image and then find defects and estimate size. Defects will be pitting, erosion, wear.
Sean, You will more than likely need a custom system to do this. What is the condition inside the pipe during inspection. We have developed similar systems, but the technology that you use is dependent on the state of the pipe, i.e., whether it has fluid in it at the time, or the resolution of the defect versus the resolution of the debris. Also can the stabilization be done after the fact, i.e., after the data is downloaded, as this is easier and less expensive than doing stabilization on the fly, which I don't think you require. Please feel free to contact us to discuss further.
Am looking for Vision SDK that allows non rectangular ROI processing.
James, Most products allow non rectangular roi. Please provide a bit more information about you are trying to do, and we'll try and point you in the right direction.
Is there vision software that specializes in inspecting porcine tissue for defects?
Miguel, Most machine vision software has similiar functions and algorithms available to inspect their products. You really need to get samples of good and bad product, and show them to a vision company, and they will be able to guide you on where you might have the problems. There are manufacturer's and integration companies on this web site that can help guide you in the right direction. We are a systems integrator based in San Diego, and our approach is typically for you to bring or send samples to us, and we'll create a vision study, to tell you how successful we think a vision inspection is likely to be, or constraints where is may not work. Please feel free to call or email me.
Dear Sir, We want to record GigE vision cameras in a M-JPEG format (low compression). Could you indicate which companies or products (SDK ?) are able to do that ? Thanks in advance.
Bresit, We are a machine vision integrator, you should be able to do this with almost any Gig E camera, speak to the manufacturers, and tell them exactly what you want to be able to do, and they can help you out. If you already have a development environment, then ask them how you would do this. If you have an idea of what you want to do with this as a total solution and have never done it before, please email me or call me, and I'll be happy to help. Alternatively these forums are designed to educate, so please feel free to ask specific questions. I do have a question for you, if you only want to do low compression, why bother compressing at all? Andy
Hello, I am looking for some info about vision software development. I am looking for applying camera inspections to a 3D printer hardware to check the quality of the printed silhouettes. By now, under my basic research I already know about GigE protocol but not much about development of software for data collection of these kind of cameras. A good pointing for my research would be very appreciated.
Rafael, If you are looking at inspecting 3D printed parts, why not use 3D inspection techniques. I know you wanted more information to do research so look for 3D laser triangulation vision systems, or stereo vision systems. You will find a number of manufacturers who produce 3D inspection cameras, and there is a lot of information on the internet about how these systems work. Gencam is also a standard that you should look at so that the images that you retrieve from any hardware manufacturer can be processed by any software vendor, at least that is the theory if the systems are genicam compliant. Good luck with your research.
We are looking for a solution to be able to identify various types of door and windows and measure their height and width, from Architectural floor plans (blueprints). There are no standards how these doors are drawn (no specific model / pattern). These blueprints/ floor plans are only available in somewhat flat PDF’s (no metadata and no vectors). Can anyone give us some suggestions on software we can use?
Naqib Please forward a per, and we'll take a look, and see if we can help you. Andy
I would like to collect data on small plants in the greenhouse and correlate that to later plant phenotype in the field. This data would be use to build a model for early elimination of plants from the production process that are unlikely to have the desired phenotype. What type of system would be used to do this?
Greg, the only systems that are capable of doing this are AI based systems. If you use a traditional machine vision approach this involves a large number iterations of software development which can become unmanageable very quickly. We are doing a lot of work in this space, if you would like to give me a call, we can talk through how you would implement something like this. We typically do this in a phased approach where we will acquire images, then train a model and then test to see if the solution is valid, before implementing a solution. Andy
We are in urgent need for a machine vision system to detect a foreign material particles of size ~10 microns and bigger on flat dark surface ~ 250mm x 150mm. We need to be able to detect these particles and remove them before next operation can commence. High volume production line of consumer electronics products Can someone recommend such system/supplier. Some level of customization might be required. Quite urgent request and implementation.
George, We are a machine vision and robotics integrator based in San Diego California. If you would like I could set up a phone call to discuss your problem, and a potential solution. We would need to get a little more into the details of line speeds, field of view, etc. If you would like to discuss further my contact details are attached.
Hello, I am looking into designing a table hockey based robot game, where vision and control would be used to track the movement of the puck and the response from the robots hockey players. It would need to be able to handle 6 players, including the goalie. Do you know of any cameras and motion controllers that could handle the speed of this type of robot game? Cost is unimportant as I just want to make it work for now. I am not sure if a micrcontroller could handle the speed of the system or if I will have to use a computer. Your help is appreciated. Thanks. Ken Walker Pokanoket Robotic Games
Ken, We have made a number of vision systems that play games. Do a search for Cyth Bot on youtube for more information, and contact us below if you are still looking for help. Andy
I am looking for a Vision System to locate a small c'bore hole 0.4mm diameter by 0.5mm deep. Needs to be VERY accurate in locating that hole.
As the problem you describe is obviously key to the vision system being successful, you need to get the sample scanned, and ensure you get the results you expect. Send us a sample, we'll scan it and send you a report.

Hi, question re getting an independent person to review an application we have with a vision system and the manufacture of nicotine patches . Would like to get a person to review the application and see if applicable for what we want it to do and dealing with the natural variability in the process.
Adrian, We are a machine vision integration company, so specialize in delivering these systems. Would you require a review of the system from a statistical verification stand point? Send me an email at the address below if you want to discuss further.
We are looking into the possibility of a vision system to grade blank rifle stocks on grain size and pattern, along with typical wood defects like knots and voids. Would you have a vision system that could be adapted for this application?
John, If you have a good idea of what you need you can send us either some stocks for a visual inspection in our machine vision lab, or some images, and we can undertake a small vision study and tell you the results you are likely to get. This would be prior to any contractual decision, as we want to know that we can do what you want, and I'm assuming you want to gain confidence in the company that you might use. We can look at a lot of the information , the real key is describing the groups. My contact information follows, feel free to call me or email me.
I am looking for talented vision system engineering resources to supplement our current staff. Can you help identify vision system engineering firms that will work on a contingent engineering (T&M) basis? My company is based in Corning, NY but we have facilities worldwide.
Edward, We are a machine Vision Integrator HQ'd in San Diego, CA, with a secondary office in Oxford UK. What are you looking to do? I can discuss with you our skill sets and see if there is a fit. This probably makes most sense over the phone. Please feel free to contact me via the contact information on this web site.
I'm trying to build a Tomato Sorting Machine.What brand & model of vision system can be perfectly used to inspect the size & defect marks on a tomato ( the tomato is moving on the conveyor ) ?
Lee, Have you undertaken any vision system development in the past. I am not aware of a "tomato sorting machine" that is available off the shelf. You may have to invest in software development time, using an adaptive type technology to solve this problem. This would involve a system that is trained to look for defects, by showing it the defects. You may also need to use 3D type technologies to look at the shape of the tomato, as well as an IR view to look for mould or rotting tomato's. We are a machine vision integrator in the USA, if you would like to talk more, please feel free to email me or call. Good luck!
We have many small labels on our products. As part of Quality Assurance we go through and read all the labels to check for typos and for proper location. The labels are just plain text. What type of system would work best, at the minimal cost, to be able to point a gun/camera at these labels, and have it convert the image it sees into the text that is on the label. The software would need to have an API that is programmable using the .NET Framework from Microsoft.
John, I noticed your question, and I wanted to pass some information your way. It is very common to focus on the software as the solution to solving machine vision problems, we are a machine vision integrator, so we use lots of software to solve problems. But the key to a good vision system is a good quality image. And I want to describe what that means. You need maximum and consistent contrast between the characters and the background. You need consistent fonts within the image. I would warn you against assuming that because the human eye - brain combination can instantly see it, that does not mean that a machine vision system can. I would ensure that you work with a lighting company and an optics company to make sure the images you get in the system give you a reliable consistent output. We make our engineers prove on the simplest task that the image is "good" by running software at it. I hope this helps you, please don't underestimate the first piece, getting a good image. Andy
Hello, I need to measure traffic volume and speed of vehicles. Is this something imaging HW and SW can do? Can you give me a few companies that may supply the necessary cameras and software? You have a large list of companies, so some direction will help.
Eric, If you want a system delivered, feel free to contact myself. We can build a system to your specs in terms of what level of detail you want to deal with. Also we use a number of differing technologies, based on environmental conditions etc.. Andy
I am investigating the use of a vision system to quantify printing defects produced by thermal transfer printing on polymer labels.
Hugh, The first thing you need is a good set of samples and a bad set of samples. We are a machine vision integrator, and we find that if the customer is able to get these comprehensive sets, then the project usually develops more easily. If you have these samples, we can run them through our vision lab, and see how complex your problem is. Andy
Hi, I have certain questions to be answered for my study on vision inspection in food and beverage industry. Can anyone help me with the size of the vision inspection market in US and Europe and the growth rate over around five years.
Anurag, The AIA has studys that describe these markets, (you may have to purchase or join AIA). Andy
We are looking for the vision systems for following missions. Do you have a capabilities and references for meeting following tasks? Quality management system which can determining surface defects on automatic transmission case for passenger cars at mass production maching line. Defects could be chip, burr, porosity, dent, oil contamination, scratch, crack, misaligned hole and hole opening.
Chong, we have made a number of systems for inspecting surface defects. Could you send me an email or a phone call to discuss your particular needs. What we like to do is get samples from you that we can run through our lab, to show you the kind of results you will get. Andy
Dear Sirs, We, are investigating an embedded vision systems, rugged and wireless, allowing realtime image per second display and zoom, on 10" monitor. Our actual research leads to wired systems, and we would like to know if some of your Members will eventually propose wireless cameras offering real time imaging, and autonomous power supply (battery, solar, wind ...).
Sebastien, The challenge is obviously not wireless transfer of data, we have all been doing this for quite some time, the challenge is real-time image transfer, and what is the consequences if the data is not sent in time. We have systems that transfer image data wirelessly, but they are only used, when are user requests a transfer, or where wireless is the only option, and if the data doesn't arrive, it doesn't really matter. The other question to consider is the data transfer protocol, UDP or TCP. TCP is what most networks are based on, and it guarantees delivery, which means it takes longer to transfer data, and you can see significant lag. With UDP the data is sent out, and if it never arrives, nobody ever knows, but with images if there is another right behind it, then maybe you don't care. How this starts to address your question. I'd be interested on what some of the camera manufacturers have to say about including wireless in the cameras in future.
I am working on a process for inspecting a 52" wide white web of fibers for any type of non-white contaminants. Ideally we'd like to detect any non-white item in the web that is 700 microns or larger. Due to upstream parts of the process, the line speed varies but is never greater than 20 yards/minute. The web is backlit and appears and is translucent in appearance (100 mils thick). Given the relatively slow speed that we are running, is it possible that we might employ used equipment (from 4-5 years ago) to reduce cost and still have an effective system. If so are there any integrators who would even be willing to work with older equipment. Any feedback is appreciated.
I would like to echo the previous statements made. The cost of labor to undertake an inspection usually far outweighs the hardware costs. One of the things I would suggest you do is provide some samples of good and bad, and the better you are able to classify your defects the more chance of producing a reasonable spec. Reddiar hit the nail on the head, when he said your system cost is dictated by resolution, and very often our customers do not think in resolution, they think in terms of defects; that I need to detect, and those that I would live with. If you can get samples of the defects you can live with, and those that are too small to worry about we would gladly run them through our vision lab, and give you a report that will help you decide. Let me also add here that you've got through the first hurdle, your asking questions in the correct forum, which ensures that you should get the knowledge that the people answering these questions can provide. Good Luck.
We are trying to find a vision system that is eligible for OCR. The piece that is to be read is a serial number (17 characters) which is engraved into a machined metal part . The part will be manually moved, so speed is not a priority. I am not too familiar with vision systems, so I was wondering what would be the best for this type of application?
Jodie, OCR tends to be tricky to get 100% success with. It is usually easy to show a demo, but repeatability is usually the issue you need to look out for. May I suggest you send samples out to either manufacturers of equipment or to Systems Integrators like ourselves. This will allow us, or companies like us to evaluate your samples, and see if we are likely to have a reliable system. We will run the samples through our vision lab and give you a report all without commitment from either side. This allows both parties to know what they are getting into. We want to know its feasible, and you want to know its feasible. I appreciate that this means you have to do more work in getting the samples together, but trust me, more work now, less stress later. Good Luck.
Hello, My company is looking for a way to verify the 2D dimensions of a flat part against a standard shape. This would be for a semi automated production packaging environment, so I am not looking for any human adjustment during the part validation. I need help identifying vendors of this type of equipment and or someone to bounce ideas off of. Thank you.
If you send us samples, we typically run them through our vision lab and show you the kind of results you will achieve. We will do this prior to any contracts changing hands, as we only want to be involved in successful projects, and this is a way of ensuring that. Are you looking for a shadow-graph type system where you only care about the silhouette or are you interested in more dimensions? We deal with 3D systems as well as 2D. We are HQ in San Diego, CA. Best of luck, feel free to contact me if you'd like.
Hi All, I am looking for some ideas on a 3D vision system that will profile and create an image of food stuffs travelling along a conveyor and the data of the profile to be then sent onto another system possibly PLC which will then, based on the data, decide on how best to portion this up. The product may be up to 800*200*150mm and up to 30 per min. Cost of a system is highly relevant and the system needs to be able to deal with uneven product surface. Thanks.
We are a machine vision integrator with Offices in California and a Support Office in Oxford UK. We deal with a large number of 3D systems, I would like to discuss your project in more detail. I am actually based in California, so 8 hours behind you, but I could give you a call early my time. We usually put products through our vision lab first to ensure that we are able to give you the data you need, and show you a report prior to undertaking a contract. If you're interested let me know. Also the Vision show is coming up in Boston in early May, if you're thinking of investing in this kind of technology it may be a good show for you to attend. We will be exhibiting there, so would be willing to host you and introduce you to the manufacturers, see the events section on Vision Online for further details.
I have a need for a vision system that will be able to count steel sheets in a stack. Example - I have a 2.5" stack of sheets 4' x 8' and each sheet is 18GA thick. How many sheets do I have? The thickness tolerance varies depending on the mill the material was purchased from, along with sheet flattness. Using simple math of measuring overall stack height and dividing by thickness of one sheet does not work. Ideal solution would be a vision system capable of detecting the edge of each sheet and adding them up. Thanks in advance.
Roman, Have you considered using a 3D vision system to monitor the gaps between each sheet, this might be a good fit to solve the different problems you are going to have with a 2D machine vision solution. If you're interested we can talk further to see if this would be an option. One other question, will you be doing this counting outdoors? Andy
We are looking for a vision solution to detect possible defects appeared on the injection molded plastic glass used for vehicle instrument cluster panel. We are currently using human visual inspection method but they have difficulty detecting those subtle defects with their eyes so I think there is a way to help them to detect those defects better.
Please feel free to contact us, we'll run some samples through our vision lab so you can see the kinds of results you will get prior to engagement.
Have 5 axis, 5'x10' table, CNC router trimming plastic parts. Would like to explore mounting a sensors, cameras, or lasers on the mast that can measure the router bit location to an accuracy of +/- .002. Would also like to put targets or sensors at the extents of the table to measure table location at rest or at a programmed fixed position.
Ken, give me a call to discuss your needs, and we'll see if we can help. Alternatively go to the vision show in Chicago next week, and you will be able to see us and all of the manufacturers at the same location. Bring along your samples and get to ask questions of everyone. Andy
Investigating if a vision system exists or can be developed which can scan various electrical connection systems and determine if the connector is fully mated. The scanning device needs to be portable and self contained such that an operator can be free to move from vehicle to vehicle checking multiple connections and connector types at various angles and/or orientations.
Bernard, I'd agree with Matt, so we have developed some Neural vision based software that can learn like a child does, so in theory it would be able to learn good versus bad, the challenge would be how to teach it the different scenerios. Could you send us some images of good and bad, that we could run through the system to see what kinds of results we would get for you?
Most examples I have seen for use of vision systems in inspections are for repetitive manufacturing operations or first piece inspections. Are vision systems capable of being used to verify mixed parts of multiple types and configurations at a rate of multiple parts per minute? Specifically trying to identify and qualify the components yielded from disassembling complete goods for remanufacture. So challenges are that the part being examined may have wear or damage, but we still need to be able distinguish which part it is and whether it should be re-used.
Duane, It is possible to inspect worn parts, but you may need to train it on typical parts that it will see. Think of the vision system like a child, on day 1 it doesn't know anything, but as it sees more and more it learns more and more and is able to distinguish between these parts if there are features that are pullled out. Please feel free to send samples, and we'll take a look at the problem you're describing. Andy
What tools can I usee to find the circumference of a circle?
Ezekeil, If you have a well defined circle, you could just measure the diameter and calculate the circumference. It depends on if you want the theoretical Diameter or an actual measurement of the length as discussed by Perry in previous post. Good Luck. Andy
I'm Alejo Raquel Jr. the Project Specialist for Unilever Philippines - Cavite Foods makers of Ladys Choice and Bestfoods Mayonnaise and Dressings. I would like to inquire if you have vision system or other inspection system that can detect crack or glass fragment inside the bottle before filling. Our glass bottle has a colored plastic label shrink around the bottle. Looking forward to receive your feedback. Thanks.
Alejo, The problem you describe is probably one of the most difficult I have seen posted on the forums in a while. Where does the fragment in the bottle come from is it part of the bottle or from somewhere else? The colored shrink wrap plastic label is going to be challenging, as even a clear bottle with defects inside that are also clear would prove difficult. Could you inspect prior to the shrink warp? How large are the fragments? What I really mean here is what is the smallest fragment that you expect to find? If its glass in food, then I'm sure the number is supposed to be zero, but that implies infinite resolution which is challenging to hit. Can you rotate the bottles and blow prior to filling, or are the fragments held on somehow? It might be that this is a problem that is easier resolved without machine vision, or you apply machine vision where the fragments are introduced. Hopefully there will be some more people on here that can give you some guidance/direction.
I am looking for a system to analyze the diameter of fiberglass filaments. These diameters are in the range of 8 micron to 50 micron. I would like a system to do batch analysis of at least 200 filaments. We are currently operating with a system to measure individual filament using a micro projection unit. I would like to have accuracy of 0.5 microns from the mean. all ideas are appreciated. Thanks you
Terry, Would you be able to provide samples, so that we can do a vision study, and inform you of how easy/difficult the inspection is likely to be. If so please contact me at the email or phone number below. Andy
Hello! I'd like to know, is it possible to count the quantity of pieces in boxes with a vision system? It would be easier to explain if I could attach an image of the box as an example.
IF you can post an image to this site, please do so, as this will allow more than one person to respond, but if you can't, then send me an email, and I'll try and give you some suggestions. It is possible though.
We are looking for vendor/s that could provide a vision system package that can automatically read/detect flaws and/or cracks on heat treated parts using magnetic particle inspection, improving the ergonomics in our plant. Prefer Midwest U.S. company (near Michigan).
Henry, I would urge you to look at the AIA Certified Vision System Integrators on the AIA web site. http://www.visiononline.org/mvo-content.cfm/machine-vision/AIA-Certified-System-Integrator-Program/id/187. This ensures that they are technically qualified and have been vetted by the organization. I believe there are a few of them in your area. Best of Luck If you can't find any one in your area, give us a call.
We are examining the capabilities of vision systems to perform blemish inspections on molded plastic bottles and are seeking to understand the achievable results within the realms of repeat-ability, reproduce-ability, and stability. Are there any published guidelines or whitepapers that address the art of the doable within the industry?
Alan, We are based just North of the border in San Diego. If you would be able to gather some defects and good parts and come to our facility we could likely run a vision study on your parts to see what results are likely. We could also show you some of the techniques that could be used. My contact information is below. A.
Hello, I am looking for way to photo id different anode blocks. In identifying the blocks, I also need a way to Quality control the anode blocks (detect them for cracking, discoloration, and spalling). I am not very well versed in this field so any advice would be greatly appreciated.
Greg, I echo the sentiments of the others. If you can mark the parts or apply "stickers" or something, then attacthing these to the product would give you the "best" solution" for tracability. If you can't then please feel free to send me an email, and you can send us samples so we can take a look at them in the lab, and see how feasible a solution is. Andy
I am looking for a vision inspection system that could be mounted outdoors (on bridges for example) looking at the surface of a flowing water body to measure invasive plant fragments that are flowing by the camera. The measurement does not have to be absolute quantity, but some relative measurement of the "flux" of fragments in the frame. This is for use in measuring the effects of invasive plants infestations flowing from streams into lake water bodies. Do you have any recommendations for a vision inspection system?
Mike, We develop solutions that use use learning techniques. Could you share some photos Pyramus with me, and we'll see if we could help. Andy
I currently have an outdoor vision system that detects logs on a stepfeeder. I am using a Cognex insight 7050 with 3.5mm focal length lens to provide me with a FOV of around 3 meters. This works well except I am having problems with sunlight causing glare and shadows that either causes the camera to false detect, or not detect at all. Could anyone recommend lighting/lens/filters that may help?
Simon, I would agree with Brian, right now you are using natural light and its variation to illuminate the object, and as this changes, this affects all the algorithms that have written to deal with "specific light setup". Having driven the coast road from Melbourne to Adelaide I know that you are lucky enough to not see too much change in weather, but your challenge remains the same as everyone else doing outside work with machine vision, having light changes makes everything else much more complicated. Brian suggested covering the environment and using lights that you control your environment - is that a practical option? If not another option is measure the light available using some other technique, get a lot of samples of images of logs for different lighting conditions, and change the algorithm based on the "type" of light available. Also you could look at different parts of the spectrum depending on your unique needs. Are you trying to measure diameter of logs as a silouett
I've been working with laser profiling sensors to generate 3D images and inspecting them with vision tools. Usually these devices only give you what is called a height image. Using this image I can measure almost anything I want but I cannot read a 2D code printed on an object or inspect the color/grayscale value of the same object. Is there a device that can deliver both Height Image and "normal image" (similar to one from a camera) or should I just use a profile sensor and camera at the same time?
It seems like sometimes the easiest solution might be the best. Why not use a 2D barcode reader alongside the 3D camera and integrate them together using software. Just a thought, there might be a dozen reasons why that won't work, but worth a look as this might be the easiest solution to implement.
I am looking for a system that would inventory similar wooden products and identify them according to distinguishing features - such as wood grain. Any products out there that would work on this scale?
Jana, We have some technology that might be able to help you. Typically we like to get hold of some samples and undertake a vision study for you. If you would like to get hold of me using my contact info below, then we can have a discussion as to how this might help. We use Artificial Intelligence to train the system just like you would train a person, so if this is something that sounds like a fit, please contact me below. Andy
Hello - I need to image a relatively large area (1mx1m) with about 0.5mm resolution. I think this means that the camera/lens system should be no less than about 4 megapixel, but of course higher resolution is preferred. I also need to stand the camera off the part by about 2m. The application is indoors where the lighting can be controlled reasonably well. It can be considered a static application - speed is not a concern. This is essentially a metrology problem where I am trying to measure a roughly 5mm wide x 1m long feature on the part. Are there industrial camera solutions with this type of resolution?
Glenn, a couple of questions for you. Are you automating the process of measuring the feature, or is this purely a visual aid to a human? Typically we would look at a resolution of 10 pixels for the smallest item you are trying to see. So using a 0.5mm maps to 1 pixel on the sensor this would give you a resolution in the one dimension of 1000mm / 0.5 mm = 2000 pixels. This will give you approximately a 2000 x 2000 pixels which is nearly equivalent to a 5 MPixel camera which is probably the most common size purchased at the moment. There are a number of camera manufacturers that produce cameras in this space. Remember the other key to a good image is make sure the lens is matched to the sensor, and the lighting that you use to highlight this part is consistent. These are especially true if you are automating the process. For more information about choosing the right components take a look at the AIA Vision Online youtube channel, which is an educational resource for component selection.
Can you tell me how to eliminate modification of ambiental light on my camera image acquisition? I have a B&W cognex camera with integrated red led light and I want to find a simple area of a black blob, but ambiental light is changing and my blob is changing his brightness.
Dan, Let me refer you to some educational videos produced by the AIA that can explain the importance of lighting, along with other items. https://www.visiononline.org/certified-vision-professional-basic-training This might help you figure out some of the issues that you are having, and also explain the different challenges with setting up a machine vision system. Betst of Luck, A.
I am a concrete construction quality professional active in many industry associations, but I know very little about image capture and analysis. I am looking for a combination of hardware and software to measure voids in concrete surfaces after the formwork is removed. Our industry currently has only subjective measurement of surface to void ratios and color uniformity; both important aesthetic attributes. I would like to build a device to capture images under controlled lighting and reflectance, and then use software to determine void / surface ratio and color uniformity. Several white papers have been written on this subject using Matlab or ImageJ for analysis of greyscale images, but the devil appears to be in the details - controlling variables.
John, You are correct the devil is in the details. How large a surface would you want to inspect at a time, and is it always out doors (poured in place) or is this inside of a plant. We have done some work with other construction companies in a factory environment, where the end user has labelled and defined the defects, by pointing and clicking - this uses deep learning techniques not traditional machine learning, just due to the large variation that I'm sure you've seen. Please feel free to contact us, and send some samples, so we can do an initial vision study for you. If it gives good results great, if it doesn't then you'll know that's not the technology for you. Andy
I am looking for a low cost solution to sort golf balls by make and model. We intend to use OCR as part of this solution. Since most ball manufacturers use alpha/numeric model numbers and logos. The challenge is getting the right orientation of text and logo for reading. Is it possible to read in multiple orientation?
Chris, Why not just use pattern matching, as opposed to reading characters. This would include logo and characters. Is this an option for you? -A.
Which machine vision systems can be used to affordably accomplish these two objectives: a) Simply detect the presence of a car within a defined space b) Determine the exact location and 3D dimension (length, width, and height) of the car within that space. Bear in mind that is objective b) the solution must detect small projections from the car such as trailer hitches off the back, mirrors off the sides, and roof racks & antennae off the roof. The distance may be from as far as 12' away and it is certainly possible to use multiple cameras to view the car from multiple angles. The solution would need to communicate with a PLC system. We currently use lasers, but they are expensive, so I am wondering if cameras would be more affordable and equally reliable.
If you are able to control options, this can have a huge impact on how much technology you need to solve your problem. For example, if you are able to control wall patterns behind the vehicles you can simplify your vision system, and therefore reduce cost. If you are able to reduce areas that you look at, again this will reduce your cost/resolution ratio. It's hard to answer all possibilities but if you want to talk through it, send an email and we can setup a call.
Hi, I'm researching different machine vision solutions for industrial QA (defect detection). Where can I find a list of the major and minor solutions providers offering machine vision solutions for defect detection? Thanks!
Vision System Design is a publication that lists these kind of things once a year. Go to http://www.vision-systems.com/index.html and see if you can find a back copy form last year, or contact the publisher.
What are some imaging applications in plant propagation?
Greg, There are almost an infinite number of machine vision systems out in the world now, and these are gathering pace, due to the AI technologies that are allowing us to do things in this space that just weren't feasible 5 years ago. Trying to relate this to you, one application is seed or plant sorting, selecting viable plants versus nonviable. Looking for disease, selecting plants which require more fertilizer. Hopefully there is something of interest in what I've just listed. As you have 'organic' items, typically Artificial Intelligence based systems is where you should probably start looking. If you need any further information, please feel free to get in touch.
