Hi everyone!
Im am curious to see if it's possible to use an arduino board together with some kind of reader to detect patterns on the back of folded paper.
If you look at the attached image you can see several black blocks aligned in a diagonal shape. Thats the shape I want to detect as an OK pattern, but if these blocks aren't aligned in a diagonal shape, thats bad.
So I was thinking if the technology behind a barcode scanner would work. Either the Laser-scanner type or Linear CCD type.
The folded paper (see picture) will be moving in the direction of the arrow and the red lines that I have painted would simulate the "scanner".
Could either the Laser or the LCCD turn these blocks into this?

How would you do it?
Or will it be a hard struggle against the grey shadow-areas?
