中文说明：自动提取平面标定板的方格角点，并进行排序，通过重投影误差最小，实现摄像机参数的标定，标定精度较高。可实现摄像机参数的快速标定。
English Description：
The grid corner points of the plane calibration board are automatically extracted and sorted. The camera parameters are calibrated by the least weight projection error, and the calibration accuracy is higher. Fast calibration of camera parameters.
