Just wondering if the camera has an auto-focus and auto-stablization modes, if there is, how can I set them via the machine vision application? Thanks, Shaun
Hello Shaun -- I suggest that you direct your question to the manufacturer of your camera. The camera manufacturer should be able to tell you what hardware and software products are compatible with their camera -- and that can provide the control you need.
The JAI CV-M71 CL camera has autoexposure and autogain. Do you know if these features operate on all three of the BAYER color layers or do they only use data from one layer.
This is a question for JAI. I recommend that you contact the company that sold you the camera and have them contact JAI for an answer.
Hello, We install several snap rings in our product which keep washers in place. But occasionally our customer reports rejects due to inappropriate snap ring gap. Is it possible to place a camera which looks for minimum allowed gap between two edges of snap ring? Thanks Salman
The short answer to your question is, "YES". A more useful answer includes several, "Depends on": Depends on the camera and its resolution. Depends on the lighting -- and how easy it is to see the gap between the two edges. Depends on the background -- and how easy it is to distinguish the snap ring from it. Depends on how quickly the inspections need to be accomplished (how many snap rings need to be inspected per unit of time. I would recommend taking pictures of a snap ring from the perspective of the inspection camera you intend to use. Make the pictures available on this forum (announce how we can see them). I'm sure you'll have several people that will be more than interested in looking at the pictures and provding an opinion.
Is there a formula to determine the field of view (how high the camera has to be in order to see said object) for a line scan camera that has to image a object 3" in height and 7" in length? Thank you for your help. Tony Werdein
There is no single formula -- but there are several factors that must be considered. 1. What is the physical length of the line scan sensor? 2. What lens mount does the camera have -- C-mount or F-mount? 3. What is the "Working Distance" ? (Defined as the distance between the front of the camera lens and the object being imaged.) Manufacturers of C-mount lenses report the view angle (angle of coverage) their lenses provide with various sizes of sensors. If you have a line scan camera with an F-mount, then you'll need to calculate the angle of coverage as a proportion -- factoring-in the sensor's length as a proportion of 36mm (the width of 35mm film). The company that sold you your camera should be able to help you with this. If you still need help, then let me know.
I want to use line scan camera to scan (in colour) with the resolution about 300dpi with object speed about 150 meters/minute. How can i calculate the line rate suitable for my application?
150 meters per minute is 2.5 meters per second. 2.5 meters per second is the same as 98.425 inches per second. 98.425 inches per second multiplied by 300 dpi = 29,527.5 lines per second. So a line rate of 29.5 kHz will provide square pixels. A faster line rate will provide more resolution in the direction of travel. A slower line rate will provide less resolution in the direction of travel.
I am looking for a remote head camera. It is very important that the remote head be as small as possible. Currently I am using s-mount / M12, 2mm lens with IR filter. I also use an small IR ring light around the lens. The lenses will be 1inch apart and 14 inches minimum from the main camera parts. The camera must run at 60 fps 1280x720 minimum resolution. Time stamp per frame and the ability to sync upto 4 cameras togeather is also very important. I would prefer a GIGe connection over any other type as the cameras would connect to a small PC and I can get multiple GIGe connections to out put to 2 SATA SSD drives. I am using these cameras to do stereo passive photogrametry of the face. Is there a camera product available that meets my requirements, even OEM? or is there a company that can build / adapt one for me? Thanks Ryan
EPIX has a color stereo camera designed for use with M12 lenses. The lenses are spaced 1” apart. You can see a picture and description of the SV9C10 stereo camera on the SV9C10 web page. The camera price, without lenses, is $1300.00. Two cables are needed to connect the camera to a frame grabber. You either need 2 PIXCI SI1 ($495 List), 1 PIXCI SI2 ($995 List), or 1 PIXCI SI4 ($1995 List), frame grabber to provide the interface between the camera and the PCIe bus. The PIXCI SI1 and SI2 will work in a PCIe x1 slot. The PIXCI SI4 requires a PCIe x4 slot. The PIXCI SI4 frame grabber can capture from 2 stereo cameras at the same time. Two PIXCI SI4 frame grabbers can be installed in 1 PC allowing simultaneous capture from 4 stereo cameras. EPIX software provides time stamps. At 1280 x 720 resolution, the maximum frame rate is 40 fps. 60 fps is available at 1280 x 554 resolution. I will be happy to help you with any questions.
We are looking for very small line scan colour cameras (multiple units). The purpose is to scan the front and the back side of a flat object, where spacing restrictions is a real issue. The cameras will need to be mounted inside an existing and the “scanning window” is about 2mm wide. We need to trigger the acquisition with an external photocell and synchronize the acquisition using an external encoder connected to the equipment.
I just have questions at this point -- How small does this camera need to be? What are the length, width, and height restrictions? What is the distance between the subject or target and the wall that restricts the camera's length? What scan rate is required -- how many lines per second? Alternatively, what is the travel rate of the target or subject? Have you considered lighting? Is the target well lit? What information do you need to collect from the captured images? Are you reading text, analyzing shades of color, counting objects? Is there a depth of field concern? Is the subject or target perfectly flat and doesn't move toward or away from the camera (vibrate) as it moves? Do you already know what optics you will be using, or do we need to provide the lens as well?
What COTS solutions for converting CL to NTSC are available?
Many graphics display boards provide NTSC output. I recommend that you contact ATI (www.atitech.com) or any other graphics display board manufacturer. These boards provide an NTSC display of everything that appears on the computer monitor regardless of whether the source is a spreadsheet, a game, or a camera link camera.
I am trying to image an object immersed in water in a clear plastic enclosure at high speeds. It is quite easy to image the object through the plastic enclosure. However, when we image the object through the water in the plastic enclosure, the image is blurred. We are hoping for a solution to this. Is there a water immersion lens that we can use and where can we get it? Any alternative solutions?
What is it about the water that creates blur? Are you required to use a longer exposure time? Is the water dirty or cloudy? What frame rate do you need? What resolution is required? What are you using for illumination? What f/stop are you using? How large is the object? What is the distance between the camera and the object? If the water is crystal clear, and if you are using the same exposure time as when you capture images without the water, then what has changed? Why do you think you are getting more blur? If you can answer these questions then I'll do my best to offer you an alternative solution.
I used to communicate CAMLINK to PCI board. (Mode full configuration) I want to "4Tap 14bit". Your set-up file is 8Tap 8bit.
Hello Byongrok Kim, EPIX has capture mode for 4-tap 16-bit Camera Link available in XCAP software with the Full Configuration Frame Grabbers. Concerning the 4-tap 14-bit case, please let me know what is the desired bit arrangement and we should be able to help you. Kind regards.
Dear ladies and gentlemen, we are using cameras with your standard in our x-ray systems. Our current preferences are cameras of the suppliers Basler AG & The Imaging Source. Both suppliers are implemented in our product lines. Unfortunately cameras of each single supplier are only working with their special software. This means whenever we implement Basler Software there will be detect only Basler products. Same with The Imaging Source. Even though all companies are working with same standard the manufacturer make sure that only won product will be detected. How is the procedure to arrange software which is not limited on specific manufacturer?! Thanks for your efforts. Mit freundlichen Grüßen / Best regards i.A.

We record structural testing of aircraft components, using several cameras which must frequently be as much as 30 meters apart, and desire to upgrade our existing surveillance-grade multi-camera system to data grade. Is there any single-source supplier who can integrate and guarantee a 4-camera system which will reliably record at 30 FPS from each camera with NO dropped frames, and at least 720x480 resolution? Would GigE be a likely interconnect technology for such a solution?
Question -- For what time period? If you only need to capture for "seconds" then real-time capture to memory may be enough. If you need to capture for minutes or hours, then real-time to hard drive array might be required.
Dear Experts, I'm looking for a system containing camera (high resolution e.g. 4 MP) and computer system where software should be devepoped and run in real time context. Date transfer rates should be min. USB 3.0 or even higher. Also SDKs like OpenCV or HALCON should run in real time context. Means there are pretty many integration aspects and dependencies that make things complex. Also operation system and computer hardware are important issues. If there's any advice you can give I'd really appreciate. All the best, Olaf Schmidt
