Cross-camera pedestrian re-identification and tracking method

The invention discloses a cross-camera pedestrian re-identification and tracking method, which comprises the following steps of: 1) image preprocessing: selecting pedestrian images from a video sequence for pedestrian re-identification, and outputting a clear pedestrian image for pedestrian re-identification by inputting a plurality of low-resolution pedestrian images; 2) cross-camera cooperativeidentification: performing feature extraction of pedestrian images, and performing feature matching of pedestrian images between cameras; 3) blind area track restoration and tracking: a, detecting pedestrians by adopting a target detection method, and inputting images of the pedestrians acquired by a camera in a vision field into a GAN network for restoration so as to realize continuous tracking of a target track; and b, calibrating the image captured by the camera and the real coordinate through a geographic information system to obtain a target starting point and a key position, and integrating through an algorithm
