Hello everyone, I have problem with camera calibration process using CirclesGrid. Generally, I am making my own camera calibration program with GUI. When I use a Chessboard and Symmetric CirclesGrid everything was ok, I set the size of board for example (6,9) or (9,6) but when I use asymmetric CirclesBoard it makes different (4,11) or (11,4). Program does a good job when I use (11,4) but in (11,4) it finds some points in wrong positions: What is wrong ?
