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.

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.

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?

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?

Hi, we are working with a sort of complex system with 8 GigE Allied Vision cameras running in 12Bit PixelFormat mode connected to a Switch with a 10Gig uplink to a virtual machine (ESXi) on which our software grabs the images. All Cameras are only used to take single frames, no video. At least 4 cameras are triggered by the same hardware trigger to grab a frame of an object. In the worst case even 8 Cameras may grab at the same time. In the last time we were facing problems with incomplete frames. We only have one try to grab the frame since the object will moving away. We tried with different parameters like PacketSize of 9K and Receive Buffers in the hardware adapters and virtual network adapters but this won't fix the problem for us. The switch itself does not report any errors and the network traffic seems not to be at any limit. It seems like the VM is having some trouble here. Using Wireshark to take a look at incoming GVSP Packets and outgoing GVCP Packets indicates that Packets are missing on the receiving side and requested for retransmission but only up to some limit. We can see that for ~200ms not a single GVSP Packet is received, like a short 'hickup'. What we want is to get this as robust as possible since we have up to 10 seconds before the next object triggers a new grab. So we have plenty of time to wait for the frames if only possible by the SDK. From my understanding several GVSP Parameters exist capable to be tuned that way but these are either not implemented in the SDK or some internal timeouts make it impossible. Has anyone experience with such a system and the GVSP protocol? Sidenote: We have set the camera bandwidths down to 10 Mb/s but this seems not to solve the problem. Looks like the problems lays in triggering multiple cameras at exactly the same time. Best regards

I am working on outdoor system for detecting fast moving objects. I need an inexpensive solution - 4 cameras shooting @ ~40 fps, 2MP, GIGE, frame level synchronization - in this case minimum 25 ms accuracy (1/40). I need roughly about 100 degrees H viewing angle per camera. The idea is to detect the objects and recreate their positions in X-Y-Z. Does anyone have any idea about the hardware setup? Its really tricky to find the right combination between sensor and optics to achieve the desired FOV at reasonable price (camera + housing + lenses should not be more than 500-600 USD). Another thing is the the synchronization, I want it to be as simple as possible, no additional trigger boxes and cables, so the sync must be done via PTP. The problem is not many cameras support PTP which makes the choice even harder or impossible.

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?

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?

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?

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.

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?

What technologies and suppliers currently exist for automatic visual or laser bore inspection? Bores can reach 1/4" and smaller if possible.

What system would you recommend for inspecting complex laser sintered metal parts made in additive manufacturing equipment. Surface finish will be typical of parts made in this process and we are looking for accuracy in the micron level with 10% gage r and r. Parts will have thin walls, and 2 cubic inch size. Cycle times in the several minute range are acceptable with least sensitivity to ambient light. Currently OGP light based systems are available to us in house but are looking for improvements/advantages.

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

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.

Is there a vision system (and approriate software) that can be used for QC/QA purposes that can quantify:1) the smoothness/roughness of a surface, 2) the distribution of particle sizes (0.5-3 mm) on a surface, 3) the color distribution of particles on the surface, and 4) the area of matrix not covered by particles?
