Pedestrian re-identification top view image selection method, storage medium and electronic equipment

Abstract

The invention provides a pedestrian re-identification top view image selection method, a storage medium and electronic equipment, and the method comprises the steps of obtaining a video of a top view angle through an image capturing device, and extracting a top view image mother set of pedestrians in the video; performing pedestrian detection on the top view image mother set, obtaining an advancing track of a target pedestrian P in the pedestrians, and extracting a top view image subset; obtaining a head center point score and a foot center point score of the target pedestrian P; and according to the screening condition and the selection condition, selecting an optimal overlook pedestrian snapshot image block from the plurality of overlook image blocks as a basis for performing feature extraction on the target pedestrian P. The problem that in the technical field of image processing and pedestrian recognition in the prior art, top view images cannot be efficiently used as model image samples to be input in the pedestrian re-recognition technology, that is, an optimal image cannot be selected from numerous top view images, so that use limitation exists in an existing pedestrian re-recognition method is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing and pedestrian recognition, in particular to a method for selecting a bird's-eye view image for re-identification of pedestrians, a storage medium and electronic equipment. Background technique [0002] At present, many public places are equipped with monitoring devices for personnel statistics; for example, shopping malls or stores usually install cameras for passenger flow statistics at the entrance and exit of personnel, so as to facilitate the macro-control of the number of people entering and leaving the mall or store , It is also convenient to accurately match the needs of personnel through big data, and improve the intelligence and convenience of shopping malls or store services. [0003] Existing cameras used for passenger flow counting are often installed vertically on the top of the building in a built-in or protruding manner. The effective body area of ​​the pedestrian...

Problems solved by technology

[0006] The main purpose of the present invention is to provide an overhead image selection method for pedestrian re-identification, a storage medium and electronic equipment to solve the problem that in the existing image processing and pedestrian recognition technology field, the overhead image cannot be efficiently used in pedestrian re-identification technology As a model image sample input, it is impossible to select the optimal image from numerous top-view images, which leads to the limitation of the existing pedestrian re-identification methods.
