Compare a PCB with 3 powered LED's by color and position compared to baseline image with openmv cam H7

Hi Commuty,

I am working on a PCB test jig and it has to compare the position and color of 3 LED,s soldered on the board. they are powered and dimmed for a clear vision. the camera is pointed straight on top and the position is fixed. I was thinking to compare it with a baseline image. it also has to test on the color of LED’s.

What would be the best approach to handle this project using what functions?

Thanks in advance


hi there,
find blobs will do what you want.
Just pass 3 regions for the 3 leds and try to find the desire color in the desire region.
no need to compare here with stored image…
