Problems solved by technology

However, these artificial features have limitations and cannot distinguish different people well, so they can only be used to assist location-based pedestrian tracking methods, rather than as the main basis for discrimination

Abstract

Embodiments of the present invention provide a pedestrian tracking method and device, and a cross-camera pedestrian tracking method and device. The pedestrian tracking method includes: acquiring a video; performing pedestrian detection on at least part of the video frames in the video to obtain a pedestrian frame in each video frame in at least a part of the video frame; for each pedestrian frame in all the obtained pedestrian frames , use the trained convolutional neural network to process the image blocks contained in the pedestrian frame to obtain the feature vector of the pedestrian frame; and match all the pedestrian frames based on the feature vector of each pedestrian frame in all pedestrian frames to obtain A pedestrian tracking result is obtained, wherein the pedestrian tracking result includes at least one pedestrian trajectory. The above method and device are not limited by position information, have good robustness, can realize accurate and efficient pedestrian tracking, and can easily realize cross-camera pedestrian tracking.

Description

technical field [0001] The present invention relates to the field of video processing, and more particularly to a pedestrian tracking method and device, and a cross-camera pedestrian tracking method and device. Background technique [0002] In existing pedestrian tracking methods, pedestrian frames of the same person in different video frames need to be matched and connected to obtain a person's trajectory. The algorithm of matching and connecting pedestrian frames is the core of pedestrian tracking. The pedestrian tracking algorithm needs to be able to judge whether the pedestrians in the two pedestrian boxes are the same person. [0003] In existing pedestrian tracking methods, judging whether the pedestrians in two pedestrian frames are the same person mainly depends on the position of the pedestrian frame in the image. However, the location-based pedestrian tracking method requires that the pedestrian frame should be relatively smooth between different video frames, an...
