Thanks for your support and advice Tim.
The RPi 4 is certainly struggling a bit at very low fps with quite some lag, so the Oak-D lite looks well worth exploring. I’ve watched your Oak-D lite video and read the guide and lots of other stuff but I’m still not entirely sure how my plan would all play out with the Oak-D lite camera?? Guess I’ll just have to get one and try it out. I’ve got the hand raising (posture) recognition working, as well as face identification (which I’ve migrated to use opencv exclusively, without the imutils functions involvement, without any real change in fps) so I can run both face identification and posture position recognotion in the same python script, but maybe I’ll have to ditch all this code to use the Oak-D lite and adapt their computer vision AI tools and samples?? Now looking at ground up opencv number plate recognition, since ALPR apparently now charges $5/month.
