No matter DLC will adapt this code or not. I hope you like this calibration idea. Work for community, work for fun. |

Ball calibration for large arena, that checkboard-corner may be too small to be seen. Maybe helpful for wide life animal 3D construction. |
|
Plus, checkboard calibration is sensetive to environment occlusions. While the ball calibration method still works fine.

Traditional one using checkboard cannot calbrate cameras >90 . And the calibration must be aligned to the main camera, not efficient.
I'm a crasy guy, i use 9 cameras around the arena. So the calibration method can not works for me.
I have done the work for multiple cameras calibration. https://github.com/chenxinfeng4/multiview_ball_calib.
Fashion, using ball calibration, a method named
bundle adjustmentin CV. It's especially useful for the camera extrinsic parameters calibration.Video demo here:
