Problems solved by technology

[0004] However, because the clothing color of the target image to be recognized may be different from that of the target image in the historical image database, the recognition accuracy of the target image to be recognized by related technologies is low.

Abstract

The invention is suitable for the technical field of image recognition, and provides a target re-recognition method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining a plurality of frames of images, each frame of image comprising a to-be-recognized target; single-frame images in the multiple-frame images are input into an appearance feature extraction network, appearance features of the to-be-recognized target are obtained, the appearance features of the to-be-recognized target are irrelevant to the colors of the single-frame images, and the appearance feature extraction network is used for eliminating interference of the colors of the images on the appearance of the target; and determining an image matched with the to-be-recognized target from a historical image library according to the appearance characteristics of the to-be-recognized target. According to the method, the problem of low re-identification accuracy of the to-be-identified target image caused by different clothes colors of the to-be-identified target image and the target image in the historical image library can be avoided.

Description

technical field [0001] The present application belongs to the technical field of image recognition, and in particular, relates to a target re-identification method, apparatus, device, and computer-readable storage medium. Background technique [0002] Target re-identification technology is an important technical means in the fields of intelligent security, missing target search, and case investigation. For example, in the missing object search field, it is used to find the missing object based on the image of the missing object. [0003] At present, in the related art, target re-identification is mainly based on deep learning technology. Specifically, the Yolo detection algorithm is used to detect each image in the multi-frame images included in multiple video files, and then crop and save to form a historical image database; The feature extraction network extracts the feature vector of each image in the cropped historical image library; finally, the image in the historical...
