Using chess board with classic colors about lichess-with-a-real-board HOT 1 OPEN

Hi Alper,

I have a similar issue. When I try to use the application app with my traveling chess set, it works great. The traveling set has a high contrast between light and dark squares, and the squares are evenly filled with 1 color. However, when trying to do the same with a more classic chess board with less contrast between light and dark squares and a wooden print, I cannot get the calibration to work.

The cv2 library doesn't seem to recognize the chessboard using the settings applied here. I tried playing around with the configuration (including preprocessing the image), but didn't manage to make it work with a chess board with a wooden print. I'll let you know and create a PR if I happen to find something that's robust in all situations, as other people might encounter the issue as well.
