Abstract

The invention discloses a pedestrian re-identification method, a device, a terminal device and a storage medium. The method comprises the following steps: obtaining an original image; detecting the original image by adopting a pedestrian detection algorithm to obtain a detection image; dividing the detection image into blocks according to a preset mode to obtain detection image blocks, and extracting features of each detection image block to obtain detection feature vectors of the detection image; obtaining M reference feature vectors, wherein, each reference feature vector is obtained by extracting the feature vectors of each reference image block after the reference image block is obtained by partitioning the reference image in a preset manner, wherein M is a positive integer; calculating vector similarity between the detected feature vector and each reference feature vector; obtaining pedestrian re-recognition results according to vector similarity. The pedestrian re-recognition method combines the advantages of local and global features of pedestrian images, and improves the accuracy of pedestrian re-recognition.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a pedestrian re-identification method, device, computer equipment and storage medium. Background technique [0002] Person re-identification (Person re-identification, RE-ID), also known as pedestrian re-identification, refers to judging whether the cameras in different positions capture the same person at different times, and can be used in video surveillance and other aspects. Traditionally, pedestrian re-identification is performed by directly extracting pedestrian features and comparing the extracted features. However, due to factors such as background, illumination, resolution, and angle of the camera's environment, the existing pedestrian re-identification effects are not good, and the recognition accuracy is low. Contents of the invention [0003] Embodiments of the present invention provide a pedestrian re-identification method, device, computer equipment, and s...
