Pedestrian re-recognition interactive retrieval method and system based on camera position

Abstract

The invention provides a pedestrian re-identification interactive retrieval method based on a camera position, which comprises the following steps: initializing a target pedestrian picture list, each target pedestrian picture comprising the position and time information of a target pedestrian; initializing a camera distance matrix and a shooting time range thereof to determine a retrieval range; in the time range, shooting being carried out through a plurality of cameras to obtain a video list; obtaining a reference pedestrian image list according to the video list, and inputting the target pedestrian picture list and each reference pedestrian image into a trained pedestrian re-identification model to obtain a retrieval result; and carrying out manual screening on the retrieval result to obtain a final retrieval result. According to the pedestrian re-recognition interactive retrieval method based on the camera position, retrieval can be carried out in a larger range, the accuracy of the result is improved, and the method can adapt to changes of the environment, illumination and the clothes of the target pedestrian.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method and system for interactive retrieval of pedestrian re-identification based on camera positions. Background technique [0002] Person Re-Identification (ReID) can be regarded as an image retrieval problem: given an image of a person captured by a camera, we need to find images of this person under other cameras. Algorithms can restore a person's behavior trajectory on the back, side or under the condition of blurred faces, and realize the identification, retrieval and tracking of the target person. It can be used to track suspects. According to the photos of suspects, go to the surveillance video library to collect video segments where suspects appear, connect the tracks of suspects in various cameras, and assist the police in sorting out clues and solving cases. Similarly, it can be used for intelligent tracing in shopping malls and stations. [0003] In practical applic...
