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?
There is a variety of industrial cameras that can fit this application. The resolution of 4-5MPx can achieved with $400-$650 camera if you don't have high frame rate requirements. Imaging Source, XIMEA cameras as well as Sentech and other vendors have cameras to serve your application. It should be possible to select a lens with low distortion to accommodate the required accuracy within the Field of View. This considering reasonably controlled lighting. With more advanced accuracy requirements you may need to correct for distortion but in your case it will likely not be necessary.
