Abstract

The present application relates to a video sequence-based pedestrian re-identification method, device, computer equipment, and storage medium, wherein the method includes: constructing a residual network, and training the residual network through training samples in a data set to obtain a feature extraction network ; Input the test sample in the data set into the feature extraction network to obtain the feature matrix of the pedestrian target sequence in the test sample; calculate the query sequence according to the dynamic time warping algorithm based on the video sequence time through the feature matrix of the pedestrian target sequence and the distance to the sequence to be matched, and output the result of pedestrian re-identification based on the video sequence. The present invention can intuitively explain the effectiveness of multi-frame information according to the dynamic time warping algorithm based on the video sequence time, and can measure the similarity of two video sequences well.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video sequence-based pedestrian re-identification method, device, computer equipment and storage medium. Background technique [0002] At present, in the field of multi-camera video surveillance, it is often necessary to detect and recognize pedestrians who have appeared in a certain field of view again in other fields of view. This process is called pedestrian re-identification. In a multi-camera intelligent video surveillance system, pedestrian re-identification is of great significance. When pedestrians are detected and recognized again, their environment such as the monitoring scene, lighting conditions, and the pose of the pedestrian itself have changed. How to quickly and accurately identify pedestrians in other conditions when the pedestrian scene and other conditions change? Detection and recognition in the field of view becomes the key to pedestrian r...
