FYI: The BeagleBone-AI may be a good fit for your project: https://www.facebook.com/photo.php?fbid=10218976824519992&set=a.2907631578284&type=3&theater
It should do machine vision _much_ better than the BBB. It's basically the SoC from the X15 in a BeagleBone form factor. I'm working on getting Machinekit working on this board and verifying capes work as expected. I couldn't say anything about it earlier, but now they've announced it at Embedded World. :) On 2/24/2019 8:53 AM, Charles Steinkuehler wrote: > I'd call 1-2 minutes for scanning slow, but that depends a bit on how > much processing you're trying to do.
