More Answers From Randall Henderson
Does anyone know the name of a vendor(s) that makes a bulkhead (panel mount) receptacle to receptacle (female-female) connector? I talked to a 3m rep. and they don't know of one, but they can make a custom cable. Any help would be appreciated.
Hi I'm Randall Henderson @ EDT Inc. We make various Camera Link component (Framegrabbers, siluators, long range adapters) and while we don't make what you're asking about, we have used a product from Carrio Cabling that I think would work for you. It's a compact F-F gender-changer that could probably be used in this to do what you ask just by using the mounting studs on one end to attach it to a bulkhead. I'm looking at one here that has part # 15255. Web site for the product is http://www.carriocabling.com/camera_link.html. Let me know if you have other questions.
Bend Radius on CameraLink cables seems to be published by the cable manufacturers as being 2.5-3.5 in. We have tight space to work in and my packaging engineer is wondering if cables are available with a tighter bend radius? If not, can a custom be made which will still be capable of meeting the spec.? If all else fails, should I be steering the design team toward a fiber optic solution?
Gore might be worth a look - they make high flex flat bend flat cable assemblies that they've tested down to 47mm bend radius -- www.gore.com. If your tight space is right at the camera or framegrabber, there are always the right-angle solutions... you're probably are aware of those but in case not, check out for example the CLCP-xx-PLx from Nortech / Intercon 1 (on this website and at www.intrcon-1.com) or 14H26-SZLX-XXX-0LC from 3M. For fiber, there are bend-intensive fiberoptics out there for down to 7.5mm bend radius -- I think most fiber optic assembly companies can supply some version, we usually work with Borg Technologies (www.borg-tech.com). Whichever route you choose I hope you will consider EDT's Camera Link framegrabbers and compact Camera Link fiber optic extender modules. Good luck in your quest.
I require a Camera link Cable with MDR male connector at one end and SDR male connector at other end with 1m length.I want to know the pin assignments for the connectors will remain same for various available commerical cables?
The 3M part number for that is 1MF26-L560-00C-100. See http://www.edt.com/PDF/ts1mf26-l560.pdf. Northwire, Nortech Systems/Intercon 1 (on this website), and Gore have similar options. The pinouts are fixed by the Camera Link specification -- go to the home page of this site then click on Vision Standards (from the left menu) -> Camera Link to download the Camera Link specification and get the pinouts.
Hi, I need a camera that can output high resolution (8MP +), large sensor (4/3" +) and high colour depth (12-bit +) images. The first two requirements are easy to find. The colour depth is challenging. Which manufacturers have easy 12-bit acquisition? Ideally outputting a 16-bit PNG or TIFF? I don't want to debayer, but I can do colour calibration, gamma etc. Any help is highly appreciated!
Try Teledyne Optech, the MS-1920 maybe? http://www.teledyneoptech.com/index.php/product/cs-ms1920/ I haven't worked with these cameras since before the company was owned by Teledyne (several mfgs back in fact) and not sure if it has the 12 bits/pixel you need but give it a shot.
Want to install wireless (or wire if wireless not feasible) cameras over a continuous steel casting project. A small PowerPoint presentation is available to give more details on the project and the associated constraints. Need help to find a robust solution to solve this request from my process department.
If you can't find a wireless solution and are using cameras with Camera Link interface you may be able to use EDT's RCX C-Link camera link extenders which provide a fiberoptic solution to the inherintly short (10M) Camera Link cable length. Replace the cable with a pair of RCX C-Links and up to 10KM of fiber and you can overcome all sorts of distance limitations if that's useful.
We are a company located in ALBANIA ,Durres; operating in security systems and communication. We are looking for a line scan camera that we can use in our project. We are planning to make a kind of under vehicle image scanner to have a scanned image of a under-vehicle. So we need a camera line-scan which can do 1024(or 2048) px b/w or colour with C mount lenses (or an adapter to use C lenses), also with an interface to connect to a PC like GigaEthernet. Can you offer us a product which can work for us and for this project? Where can we find a store to buy your products, can you sell directly? Please send us a detailed offer technical and economical for the products that match our needs. Thank you & Best regards
Not sure I can help with the camera but there are several camera manufacturers out there who make line scan... Basler, DALSA and e2v are some that I've worked with and would recommend. They make cameras with Gig-E and Camera Link, and if you end up with a higher data-rate camera it will likely have Camera Link output. In which case you'll need a framegrabber and cable. Camera Link cables are limited to 10 meters, and the under-vehicle scanning systems we've dealt with typically have the camera more than that from the receiving computer so if you wind up it situation, take a look at look at EDT's RCX C-Link Camera Link fiberoptic extenders / repeaters and framegrabbers,
We want to develop a grain sorting system for which we want to use a line scan camera. Please suggest a suitable camera and algorithm. The dealer is in India.
That's a pretty open question. There are many line scan cameras out there with different sensor sizes, light sensitivities, speeds, etc. etc. Someone would need to specify all of those to come up with a meaningful answer for you. I can say that Dalsa (www.dalsa.com), Basler (www.baslerweb.com) and e2v (www.e2v.com) are the main manufacturers of line scan cameras, so you should look at them for a start and see if anything meets your specs. If you choose a camera with Camera Link output, you will need a Camera Link framegrabber board to get the image data into the computer, and EDT can supply you with boards that run on Windows, Linux, Sun Solaris and Mac OS. We also provide long range fiberoptic repeaters that replace standard camera link cables that can otherwise only go 10 meters. See www.edt.com for more on that.
I am a graduate student from University of Florida. My group are now working on a visualization study of cryogenics. I am looking for a camera which can take about 300s video at about 2000fps. The resolution is not a mean concern. We hope the camera can be as small as possible. Thank you for your advice.
I suggest you look at Scimeasure cameras. They have various frame sizes with high frame rates, used in astronomy (adaptive optics), microscopy and other applications. Their website seems to be down right now but the main guy there is Charlie Bleau. For any camera with these speeds, it's probably going to be outputting Camera Link so you will also need a framegrabber. I believe Scimeasure bundles them with the cameras but some other camera mfgs don't -- that is what our company does however (make framegrabbers, as well as long range adapters to go beyond the maximum for Camera Link over standard cables (up to 10KM) as well as simulators and high-speed / high-capacity data recorders.
I would like to ask if there is any chance that I can find cameras which are used for 24/7 on the road and used for car License Plate capturing. I don't want to set the day and night - I want the camera to automatically fine tune itself and its settings to make sure clear license plates can be captured. If yes, can you give me some suggestions for the potential partners or suppliers.
I know several manufacturers provide cameras with Auto Exposure. The first one that comes to mind is the Basler Aviator series. The ones with the highest framerates will be the Camera Link versions so if you choose a Basler or any other camera with Camera Link output you'll need a framegrabber and possibly an extender to get the data further than the standard 10M for camera link, both of which EDT can provide. Give us a call if you have other questions.
We are doing a Street view job. I need suggestions for a camera with this specs: - Electronic shutter, as too many photos can wear off mechanical ones. - Ability to program continuous shooting or command shooting from outside software by USB or Serial cable - Have to be able to work with external power (many photos require a lot of power) - External memory, image stabilization
Juan, Can't help you with a camera but if you choose one with Camera Link output be sure to check out our RCX C-Link remote camera adapters that let you site your camera much further than with normal camera link cables (up to 10KM instead of 10M) and propogage image data uncompressed as well as camera link control (CC) lines and also have an option for independent serial channel, all over the same fiber.
I am trying to develop a generic C# interface for Vieworks VH series camera so that I can capture an image and subsequently process and analyze the image for decision making purposes, be it for video analytics and machine vision. Is there any supporting library that I can base on or any development guide that I can get hold of? If there is cost incurred, pls. advise me on the price as well.
What is the output? If it's Camera Link your software will depend on the specific framegrabber used and what libraries they supply. What framegrabber are you using, or do you have one yet?
Hi I'm intersted in changing the AOI (width, height) "on the fly". Does the standard support it? I've seen the GeniCam defines TLParamsLocked parameters which allows to announce that a register is locked. Does it allow to lock all registers? Best regards, Tal
Which standard? I can't speak to Gig-E but with Camera Link (assuming it's using GenICam for Serial), the answer is, "it depends," on the framegrabber and camera. Not all cameras have AOI but of those that do, most support switching AOI on the fly. However the framegrabber may need to also get the message, since switching camera AOI doesn't automatically change the FGs idea of how big the image is, and it may also require a separate change to the FGs registers to match the changed width / height from the camera. In the case of EDT's PCI DV series framegrabbers for example, you would send the serial command to the camera to change AOI and also call pdv_setsize() with the new size for the framegrabber. Alternately, some framegrabbers can do AOI on their own without changing the camera's AOI. In that case the camera continues to output the full image data but the framegrabber clips the data to the specified AOI. EDT's framegrabbers can do this with any camera.
Dear Sir, For a project with a customer, we need to measure in near real-time speeds of impacts between one object and a projectile. This requires a high-speed camera. The requirements of the camera are: - min. output frame resolution: XGA (1024x768) - speed (in fps): as close as possible to 1000 fps. - Thunderbolt, GigE Vision or Camera Link OK - autofocus - wide angle (optional) What manufacturers provide this type of cameras? Thank you for your help, BR, Jerome PIAT
Mikrotron, Basler, Dalsa, among others. Only CameraLink or one of the new standards (HS, CoaXpress) will handle that kind of throughput. Okay Thunderbolt too but are there any cameras yet? I haven't seen em. For CameraLink you'll also need a framegrabber, and extender if you need to go further than 10 meters with it. Please consider us for those.
In our optical system we have observed that when we replace the B/W camera with a higher resolution camera (same optical format but smaller pixel size and larger pixel) we observe a much more gray image, the image has much less contrast with the high resolution camera. Example substituting a 2MP, 1/4 " optical format with a 5MP, 1/4 optical format causes a much less contrast and detail. How do we adjust for this?
Could be a bit depth issue. If your original camera sent 8-bit output but the new one sends 10 or 12 for example but it's still being captured as 8-bit, you could be viewing the data with bits shifted over by e.g. 2 or 4 bits, which would manifest as a low-contrast image. May just need a configuration change -- what camera is it, and what standard (Camera Link, Gig-E, USB vision, ???) Randall Henderson EDT inc, 503-748-7896
Why can PoCL not be used in medium or full mode?
PoCL for base, medium and full mode are all defined for CameraLink v2.0, but base and medium are not for v1.2. If your devices are v2.0 compliant, they should support PoCL in all configurations. What are your specifics?
I used to communicate CAMLINK to PCI board. (Mode full configuration) I want to "4Tap 14bit". Your set-up file is 8Tap 8bit.
The answer will depend on what PCI board you have. You will need to provide information about the PCI board manufacturer including which setup file, or contact the board manufacturer directly.
We are using several cameras using camera link Is it a generic SDK which make us able to write an interface usable on any camera? Is it in Camera Link specifications a definition of time stamp and image counter?
Hi Gabriel, There's no standard SDK for Camera Link cameras, and while there is a standard way to communicate serial using the serialXXX.dll, the serial command sets vary from mfg. to mfg. Some mfgs have adopted the GenIcam standard but not many, and that still only covers the serial control side of it. However many framegrabber manufacturers provide their own APIs that standardize camera functionality to the extent possible. For example EDT's API supports a variety of cameras out of the box and includes convenience functions to perform many tasks in a camera-independent way. We also provide frame-counter and timestamp functionality on the framegrabber side which can be used with any supported camera. So while it may not constitute a completely camera-independent SDK, it's a step in that direction. There may be integrators who have developed general purpose toolkits that support a subset of camera manufacturers' devices -- if so hopefully they will chime in too.
Do adapters or converters from a Camera Link-interface device to FireWire exist?
Not that I'm aware of. But fiberoptic and coaxial are options.
I'm interested in sending data to camera without ACK from camera. Does the standard support it? I saw there is a message channel, but its direction is camera to application. Thanks, Tal
Which standard? AIA supports several standards. In general I would say the answer is no but it will depend on the standard and also the camera -- with Camera Link there's no "standard" command / response protocol, the standard just provides for a connection but it's up to the camera mfg. to decide what to say across it, and most don't require an ack (even if they send one).
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?
Hi Paul, Where would the validation occur? Are you looking for something that reads the spreadsheet file before it gets uploaded, or something that would go the toolchain that's used to upload the spreadsheet? Feel free to email me offline.
In the Camera Link interface, is the image data transfered in Bayer format, or RGB?
Either one. To reduce transfer bandwidth, most cameras using a bayer filter sensor send the raw Bayer data, which is transmitted the same as a monochrome image, and any bayer decoding gets done either in board hardware, or via post-processing on the host computer. Either way the decoding step is not part of the Camera Link specification so any method for enabling and performing that will be framegrabber-or application-dependent. 3-CCD cameras and some bayer cameras send as RGB data. Usually it's 24 bits per pixel, 1 or 2 taps, and most FGs have standard ways of handling that. Less commonly you'll get greater pixel depth, e.g. 10 bits per pixel as 32-bit data. In that case the MUX at the FG end may be different depending on the FG -- for example it might be the MSBs of RGB in the first 3 bytes, then the LSbits as 2R 2G 2B 20. Feel free to email me if you have any other questions.
How many can the simultaneous produced digital image data be handled by CameraLink system? For example if I had a multi-bands camera (eq.10 bands), each quantified in 10 bit, is CameraLink able to handle this 10x10 simultaneous bits data? How is it implemented?
If I understand your question correctly, the answer would be 80 bits. The Camera Link specification includes many combinations of channels and bits, including 10 channels x 8 bits and 8 channels x 10 bits. It's up to the framegrabber or post-processing software o sort out that last one so you wind up with something you can display / process, for example unpacking the 10-bit pixels into one 16-bit word each. For more details see the Camera Link specification, available under Vision Standards on the AIA site.
I have a requirement to test a camera used in our medical imaging systems. The image originates from a 1K x 1K CCD sensor but the actual output of the camera where I need to test and measure is analog. I would like to reconvert the signal to digital and ideally into Camera Link compatible format with minimal affect on signal quality. I would like to use a frame grabber board but I have not seen any that will accept analog input. Can you recommend a solution?
Darrell, I presume you need this because you have some specialty analog camera that can not be replaced with a Camera Link camera? I haven't come across any analog to Camera Link converters but if you really need it to be Camera Link for some reason (would be good to know why) then one possible solution would be to get the data into a computer via an analog input board, then ship it out via EDT's PCI DV CLS board which can take raw or formatted data and send it *out* as Camera Link. That would essentially mean a whole computer is acting as the Analog to Camera Link converter. We also have Camera Link input boards -- check out our website.
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, There are several manufacturers who make high-speed motion cameras -- Princeton Instruments / IDT's M2 and M5, Basler's A504K and Mikrotron's EOSENS cameras can all capture upwards of 500 FPS at varying resolutions. I'm not sure what you require for the robotic game but it seems that would do it. These cameras all produce Camera Link output which requires a high speed framegrabber to capture the data. I work for EDT who makes framegrabbers that can capture these speeds , and our PCIe8 DV C-Link board can work with most models of the above cameras. For more see our website.
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.
