System calibration method and system based on corner detection and feature point extraction

The invention relates to the technical field of corner detection, and particularly discloses a system calibration method and system based on corner detection and feature point extraction, and the method comprises the steps: S1, collecting a calibration plate image through a binocular camera, and respectively detecting the corners of a checkerboard calibration plate; s2, running a calibration algorithm according to the world coordinates and the image coordinates of the corresponding angular points to obtain camera parameters and position data between the cameras, and correcting the binocular camera according to the camera parameters and the position data between the cameras; and S3, performing parallel equipotential verification according to the corrected image to complete the calibration process. According to the method, the matching point pairs in the visible light edge image and the infrared edge image can be calibrated without a calibration plate of feature information, image edge detection and feature poi
