Calibration and image correction method and system for binocular wide-angle camera

The invention discloses a calibration and image correction method and system for a binocular wide-angle camera, and the method comprises the following steps: obtaining images of a same checkerboard calibration plate through a first binocular camera and a second binocular camera, and determining image corners according to the images; acquiring internal parameters and relative poses of the first binocular camera and the second binocular camera based on the image angular points to complete camera calibration; mapping latitude and longitude coordinates of pixel points in the calibration plate image acquired by the first binocular camera and the second binocular camera to two-dimensional plane coordinates; disparity maps of the first binocular camera and the second binocular camera are obtained, and three-dimensional points in the space are generated based on the disparity maps, so that three-dimensional reconstruction is completed. According to the invention, no visual field is lost, and the advantage of large vi
