根据棋盘图，自动获取角点，标定相机的内、外参数-Camera Calibration

一束线激光投射到双平面棋盘格的相纸上时，用CCD拍图，对高斯光束的分析，光条的横截面光强近似服从高斯分布，那么光条的中心可以认为在光强分布的峰值点，所以采用加权平均的方法得到两个光条中心坐标（u1’,v1’）和（u2’,v2’）(When a beam of line laser is projected onto a photographic paper of a double-planar checkerboard, the Gaussian beam is analyzed using a

自定义棋盘格生成程序, 配合视频截图和Opencv自带相机标定例程可以很好标定相机(Custom checkerboard generation program, combined with video screenshots and Opencv camera calibration routine can calibrate the camera well.)
