We have written an EPICS driver for USB Video Class Cameras (UVC) which encompass most consumer webcams. We have tested it with several cameras ranging between 50 - 200 $
It is available here: https://github.com/epicsNSLS2-areaDetector
in the ADUVC repository. Also character recognition can probably be done in OpenCV w/ some form of machine learning, and we have been developing a Computer Vision plugin in the ADCompVision repository that could be a good start.

All: Has anyone developed an Optical Character Recognition plugin for AreaDetector? The potential use case is to have a camera aimed at an instrument front panel, and digitize the display to extract the instrument's displayed output. I've already anticipated the potential problems associated with multiplexed displays that may introduce artifacts into the digitized images, so I don't want to attempt to develop something that may be a failure anyway. Are there any classes of inexpensive low resolution cameras supported by AreaDetector? Like consumer grade webcams, for instance? Yes, it's a hack, but easier than the alternatives in at least one known case. Rod Nussbaumer TRIUMF Vancouver, Canada ------------------------------ | |||
