Abstract

The invention relates to visual detection technology, and discloses an abnormal behavior analysis method based on the intelligent linkage of multiple video cameras, which includes: performing frame-by-frame processing and key frame screening on video data of multiple video cameras to obtain a target frame image; Reconstructing the background image and stripping the background to obtain the behavior and abnormal behavior library of the moving object; according to the correlation weight of the moving object and the multi-video cameras, extract the behavior collection of the moving object from the target frame images corresponding to the multi-video cameras, according to the behavior collection The behavior characteristics and skeleton characteristics of each behavior are calculated to obtain the motion behavior and limb behavior of the moving target; the abnormal behavior of the moving target is determined according to the abnormal behavior library for the motion behavior and limb behavior. The invention also provides an abnormal behavior analysis device based on the intelligent linkage of multiple video cameras. The present invention can improve the accuracy of abnormal behavior detection and the flexibility of detection in different environments.

Description

technical field [0001] The invention relates to the technical field of visual detection, in particular to a method and device for analyzing abnormal behavior based on intelligent linkage of multiple video cameras. Background technique [0002] With the vigorous development of artificial intelligence and computer vision, vision-based abnormal behavior detection has become a research hotspot. At present, the identification and detection of abnormal human behavior has been widely used in social production and life. In the field of medical monitoring, through abnormal behavior recognition and detection technology, real-time monitoring of unsupervised patients or the elderly can be realized, to determine whether the target has fallen or other accidents, and to call for help in time to ensure that they receive treatment and help in the first time. ; In the field of traffic safety, the abnormal behavior detection technology can monitor abnormal conditions inside and outside the ve...
