I'd call 1-2 minutes for scanning slow, but that depends a bit on how much processing you're trying to do. Given that sort of time frame, I think the main problem you might have with the BBB is running out of memory, but again that depends on what you're trying to do.
For the control, I'd suggest using a tablet/smart-phone and setup a remote interface using QtQuickVcp. You might also be able to use a camera on the tablet for your scanning. I'm not sure if that would be easier or harder than doing the scanning with the BBB. NOTE: You can get a USB-OTG cable and connect most tablets directly to the USB Client port on the BBB. The table will see the gadget Ethernet driver on the BBB and automatically setup networking so you don't have to communicate via WiFi. I do this with a 7" RCA Voyager tablet I bought for ~$35. It's not a great tablet, but the touch-screen works fine for a UI! On 2/24/2019 7:33 AM, jonas hauptman wrote: > Thanks! > > I am not worried if the vision scanning routine takes 1-2 minutes.
