Abstract

The invention discloses an anti-blocking pedestrian tracking method and device and a storage medium. The method is used for solving the technical problem that in the prior art, the accuracy of tracking pedestrians in a dense environment is low. The method comprises the following steps: acquiring a current frame detection frame and key points corresponding to each pedestrian in a current frame image, and associating the current frame detection frame corresponding to a first pedestrian with the current frame detection frame in all pedestrians with all key points corresponding to the first pedestrian; matching the current frame detection box corresponding to the first pedestrian with each track obtained from the historical frame image, and updating the first track, wherein the current frame image and the historical frame images belong to the same video, one pedestrian forms a track in a plurality of historical frame detection frames in all the historical frame images, and the first trackis a track successfully matched with the current frame detection frame; and matching the second track which is not matched with the current frame detection box in the historical frame image with the key point which is not associated with the current frame detection box in the current frame image, and updating the second track.

Description

technical field [0001] The present invention relates to the technical field of tracking, in particular to a method, device and storage medium for anti-occlusion pedestrian tracking. Background technique [0002] Pedestrian tracking has a wide range of application scenarios in the security field, such as people flow statistics, traffic supervision, and even some face recognition devices will also add tracking modules to improve recognition accuracy. [0003] However, when tracking pedestrians, the occlusion problem has always been a difficult problem in pedestrian tracking. In the prior art, most of the target motion information and target appearance information are used as auxiliary to solve the occlusion problem. [0004] However, in a scene with dense pedestrians, the movement information cannot effectively locate the target position due to the dense crowd, and there is a high probability that there are pedestrians with similar clothes, which leads to the probability of f...
