Abstract

The invention provides a multi-target tracking and behavior analysis method and system and a storage medium, and belongs to the technical field of target tracking. The method comprises the following steps: detecting a first target in a video image by adopting a pre-trained first target detection model; detecting a second target in the video image by adopting a pre-trained second target detection model; under the condition that one of the first target detection model and the second target detection model detects the corresponding first target or second target, generating a first target detection result; under the condition that the other one of the first target detection model and the second target detection model detects the corresponding first target or second target, generating a secondtarget detection result; extracting features of space-time interest points of the first target and the second target according to the first target detection result and the second target detection result; projecting space-time interest points; and intercepting a sequence of the spatio-temporal interest points according to a set time window so as to analyze behaviors of the first target or the second target.

Description

technical field [0001] The present invention relates to the technical field of target tracking, in particular to a method, system and storage medium for multi-target tracking and behavior analysis. Background technique [0002] With the rapid development of social economy, the application of video surveillance system in various industries is gradually maturing, and the number of cameras built and put into use is increasing rapidly. Since the monitoring system collects a large number of videos, real-time monitoring of these videos has gradually become a big problem. It is difficult for users to keep on the alert if they keep staring at the screen, and it is impossible to analyze subsequent data loss. Therefore, it is necessary to adopt an intelligent analysis system to analyze the video while collecting it. [0003] In the prior art, in the related research fields of computer vision and pattern recognition, multi-view human behavior analysis has always been one of the most a...
