  • Who is at the coffee machine? Facial Recognition using Raspberry Pi, OpenCV and Sigfox

    El classico: check your hardware first! The issue was that my raspicam spontanously died. Now it works so far with another one, but when I captured the positive images and train them and try to identify myself infront of the cam with the test.py it just doesn't recognize me. Which values for the confidence factor did you tried? I mean I'am just up to that point and want that my name pops up in the terminal. Any ideas? What troubles did you ran into when you set it up?
