OpenCV之相机畸变矫正

opencv 4.4

vs2017

代码是借用人家的，具体哪篇也忘了~

程序运行后按Y键持续检测角点直到输出

角点找不到的原因分析 这里设置标定板的角点数错误，行列应该设置为你标定板最大格数-1，我的标定板是7行10列这里就设置(6,9)

另外还有可能标定板离的太近

Size patternsize = Size(6,9); /* 标定板上每行、列的角点数 */

另外个容易出问题的地方在这里 COLOR_RGB2GRAY，由于opencv版本的变化这里可能会报错，老的版本可能是cv::CV_RGB2GRAY，主体意思就是把传进来的图片变成灰度图

cvtColor(imageInput, gray, COLOR_RGB2GRAY);
