实现对图像的按网格的切割，编译需要使用opencv-To realize the image of cutting according to the grid

结合实例 利用opencv软件对相机进行标定，标定方法基于张正友的平面格网法。-With examples using opencv software to calibrate the camera calibration method based on Zhang Zhengyou plane grid method.

vs2008+opencv环境下，圆柱形棋盘的自标定程序，不使用库函数，自定义算法。可自动判别不同角度拍摄的圆柱棋盘照片上的可用网格数量，进而成功实现标定。-Vs2008+ opencv environment, cylindrical board since the calibration procedure, do not use the library function, the custom algorithm. Can automatically recognize cylindric
