I’ve constructed the BricKuber Rubik’s cube solving robot but am having trouble with the quality of the pictures that the RPi camera (V1.3) is taking of the cube’s faces.
On the very rare occasion that the solver manages to take and analyse all 6 faces, the code always returns the message
Error: Error. Probably cube string is invalid
I can see why that may be by looking in /tmp at the photos of the faces. The contrast changes radically between faces despite the illumination remaining the same throughout.
Can anyone suggest what I could try to correct this problem? Perhaps change the options to the
rspistill command? The default settings in
-w 300 -h 300 -t 1 --imgfx cartoon -o ...
My other thought is that maybe the V1.3 camera is not up to the job and I need a V2?
