Abstract

The invention relates to a visual inspection technology, and discloses an abnormal behavior analysis method based on intelligent linkage of multiple video cameras, which comprises the following steps of: performing framing processing and key frame screening on video data of the multiple video cameras to obtain a target frame image; background image reconstruction and background stripping are carried out on the target frame image to obtain behaviors of the moving target and an abnormal behavior library; according to the association weights of the moving target and the multiple video cameras, extracting a behavior set of the moving target from the target frame images corresponding to the multiple video cameras, and according to the behavior feature and the skeleton feature of each behavior in the behavior set, calculating to obtain a moving behavior and a limb behavior of the moving target; and according to the abnormal behavior library, determining the abnormal behavior of the motion target for the motion behavior and the limb behavior. The invention further provides an abnormal behavior analysis device based on intelligent linkage of the multiple video cameras. According to the invention, the accuracy of abnormal behavior detection and the flexibility of detection in different environments can be improved.

Description

technical field [0001] The present invention relates to the technical field of visual detection, in particular to an abnormal behavior analysis method and device based on intelligent linkage of multiple video cameras. Background technique [0002] With the vigorous development of artificial intelligence and computer vision, abnormal behavior detection based on vision 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, it is possible to realize real-time monitoring of unattended patients or the elderly, determine whether the target has fallen or other accidents, and call the police in time to ensure that they receive treatment and help in the first place ; In the field of traffic safety, abnormal behavior detection technology can be used to monitor abnormal conditions inside ...
