This is the source code of camera calibration based on OpenCV, it use computer camera to do chessboard calibration.
Camera calibration instructions: the process of using OpenCV for camera calibration can be found in help documentation of OpenCV. It is very useful. I am here to explain some key points, wish will be of helpful to everyone.
First, since the actual coordinates of the grid is random(there is a certain method), it means that "the world coordinate system is dynamic, each image has one", so each image has an outer parameter matrix;
Second, from the general work after calibration, we know that the external calibration parameters calculated in this step are basically useless, so we do not care about the external parameters;
Third, our main concern is the inside parameters, the inside parameters will keep unchanged as long as the focal length of the camera keeps unchang
