Thinking of this lib:
I want a chess camera. When I play chess, a camera could record the game, so I could for example upload a pgn file of it later.
The lib looks really impressive.
For recording a chess game, it doesn't need to know which piece is on which square all the time. It can know which piece is where by knowing the setup, and then follow the moves. Pawn promotions can be guessed later.
But I have some doubts about it:
Will hands covering the board ruin it?
Can opencv run on a phone?
Why didn't someone make it already?
