How to calibrate the rotation center of the upper camera
1. Put the calibration plate in the camera's field of view, and make sure that the calibration plate is completely visible and the camera can shoot multiple angles of the calibration plate.
2. Use a camera to shoot multiple images containing the calibration plate, and use image processing software (such as OpenCV) to extract the corners in the calibration plate images.
3. By calibrating the camera at diagonal points, the internal parameter matrix and distortion coefficient of the camera can be obtained, and the calibration results can be used to correct the image to verify the accuracy of the rotation center.
