Pedestrian re-recognition method and device

Abstract

The invention discloses a pedestrian re-recognition method and device. The method comprises the steps of obtaining a to-be-recognized human body image; inputting a to-be-recognized human body image into the trained pedestrian re-recognition model to obtain a recognition result; wherein the pedestrian re-recognition model comprises a backbone network, a multi-channel global generalized average pooling module and a full connection layer; the backbone network is used for extracting N three-dimensional matrix features, used for identity recognition, of the human body image; the multi-channel global generalized average pooling module is used for converting each three-dimensional matrix feature into a one-dimensional feature through multi-channel global generalized average pooling; the full connection layer is used for obtaining a total one-dimensional feature according to each one-dimensional feature; and calculating the similarity between the total one-dimensional feature and the one-dimensional feature of the known identity human body gallery, and taking the identity corresponding to the one-dimensional feature with the highest similarity with the total one-dimensional feature in the known identity human body gallery as a recognition result. According to the embodiment of the invention, the robustness of a pedestrian re-recognition effect is enhanced, and the accuracy of a pedestrian recognition result is improved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a pedestrian re-identification method, device and storage medium. Background technique [0002] In indoor places with a high level of confidentiality, only specific personnel can enter and exit a specific area during a specific time period. In response to the confidentiality requirements of this kind of place, access control can be added to specific areas. However, although the addition of access control solves the need for confidentiality of the place, it also has shortcomings. On the one hand, the difficulty and cost of adding access control is directly proportional to the number and subdivision of confidential areas; on the other hand, the existence of access control will bring inconvenience to the passage of staff in confidential places. [0003] In recent years, with the development of computer vision technology, the intelligent analysis and monitoring sy...
