The invention discloses an image processing method for a panoramic vehicle safety system based on multi-camera self calibration. The image processing method relates to automatic recognition, automatic correction, automatic view angle conversion and automatic splicing image conversion. The image processing method specially comprises the steps that calibration cloth recognition is conducted on collected images, and the position information of edge corner points on checkerboard calibration cloths of the collected images are extracted automatically; a distortion model is established, distortion parameters are iterated, and a distortion correction map is obtained; affine transformation is conducted on the distortion correction map to obtain images after view angle conversion; the images collected by a plurality of cameras are subjected to transformation processing and marked by encoded points, and the images collected by the cameras are spliced and integrated. Compared with the prior art, the image processing method for the panoramic vehicle safety system based on multi-camera self calibration has the following advantages that the method supports splicing of any multiple cameras, splicing is convenient and fast, a user only needs to input the number of the cameras, the calibration cloths are matched for use, and a panoramic image can be spliced in a full-automatic mode.
