摄像头标定的代码,OPENCV没有提供完整的示例，自己整理了一下，贴出来记录。利用cvFindChessboardCorners找到棋盘在摄像头中的2D位置，

再用cvCalibrateCamera2计算内参，

最后用cvUndistort2纠正图像的变形。

-Camera calibration code, OPENCV did not provide a complete example of its own collation, then paste it records. The use of chessboard cvFindChessboardCorners found in the 2D camera position, and then calculating the internal cvCalibrateCamera2, and finally used to correct image distortion cvUndistort2.
