Group behavior recognition method and system

Abstract

The invention belongs to the technical field of behavior recognition, and provides a group behavior recognition method and system. The method comprises the steps: obtaining a to-be-recognized video; determining a group motion area of the to-be-recognized video; determining feature points through a target detection algorithm, tracking the feature points, connecting the feature points in space, and obtaining a spatial-temporal feature body description operator containing group interaction information; inputting the spatial-temporal feature body description operator into a behavior recognition model, and outputting a behavior recognition result, wherein the process of determining the feature points comprises the steps of extracting global features of each pedestrian and Upper features of the upper half face from the group motion area, fusing the global features of each pedestrian and the Upper features of the upper half face to obtain fused features of each pedestrian, and determining the feature points representing the pedestrians in the group motion area according to the fused features. The accuracy of group behavior recognition is improved.

Description

technical field [0001] The present disclosure relates to the technical field of behavior recognition, in particular to a group behavior recognition method and system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In recent years, with the rapid development of intelligent monitoring system and image processing technology, intelligent monitoring equipment has been widely installed in the field of public security, and the number is increasing year by year. At the same time, with the rapid development of the global economy, rapid social progress, and the continuous improvement of the comprehensive national strength of various countries, social security problems are becoming more and more serious, ranging from large public areas such as shopping malls and stations to small residential areas and school dormitories. The demand for real-time r...

Problems solved by technology

[0004] The existing group behavior recognition method mainly recognizes the behavior of the group by extracting the behavior characteristics of a single pedestrian. The inventors of the present disclosure found that in a complex scene, pedestrians block each other or block each other to target segmentation, Target tracking brings great difficulties, so the effect on group behavior recognition is limited
