Abstract

The embodiment of the invention provides a pedestrian re-identification method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining all to-be-identified sub-feature map sequences of a to-be-identified pedestrian image by using a feature extraction network; calculating the similarity between the to-be-identified pedestrian image and each reference pedestrian image based on all to-be-identified sub-feature map sequences of the to-be-identified pedestrian image and all reference sub-feature map sequences of each reference pedestrian image; and generating a pedestrian re-identification result of the to-be-identified pedestrian image based on the similarity between the to-be-identified pedestrian image and each reference pedestrian image. When the to-be-identified pedestrian image is a whole-body image or a non-whole-body image to which the to-be-identified pedestrian image belongs and / or the reference pedestrian image is a whole-body image or anon-whole-body image of a reference pedestrian to which the reference pedestrian image belongs, , the similarity between the to-be-identified pedestrian image and the reference pedestrian image can be calculated accurately and pedestrian re-identification can be completed accurately.

Description

technical field [0001] The present application relates to the field of computer vision, and specifically relates to a pedestrian re-identification method, device, electronic equipment and storage medium. Background technique [0002] Person re-identification (person re-identification) is an important research topic in computer vision, especially with the growing related needs in video surveillance, smart security and other scenarios, person re-identification has gained more and more attention. [0003] At present, the pedestrian re-identification method adopted can only perform pedestrian re-identification when the image of the pedestrian to be recognized is the whole body image of the pedestrian to be recognized to which the image of the pedestrian to be recognized belongs, that is, the image of the pedestrian to be recognized includes the entire body of the pedestrian to be recognized. Pedestrian images to be recognized are usually acquired from surveillance images that in...
