Abstract

The invention discloses a human body abnormal behavior recognition alarm system and method under panoramic monitoring based on posture estimation, and belongs to the technical field of intelligent monitoring systems. 360-degree video acquisition is realized by using a panoramic camera, and bone key point coordinates of a human body are extracted as feature input of a human body behavior recognition algorithm based on a deep learning human body posture estimation algorithm; a space-time diagram model containing space information and time sequence information is formed through coordinates, multi-stage space-time diagram convolution operation is carried out on a space-time diagram, advanced features are extracted, finally behavior classification is carried out through a SoftMax classifier, a behavior result is obtained, and whether the behavior is an abnormal behavior or not is judged. The system and the method have the advantages of being wide in collection view field range and free of blind areas, human body abnormal behavior detection under the panoramic monitoring system can be processed in real time, local alarm can be given in time when abnormal behaviors just happen, a remote manager can obtain alarm short messages in time, and meanwhile field conditions can be checked in real time through a mobile phone.

Description

Technical field

[0001] The present invention relates to a human abnormal behavior identification alarm system and method under the panoramic monitoring of posture estimation, belonging to the technical field of intelligent monitoring system. Background technique

[0002] In recent years, violence in public places has made the community to realize the necessity of security monitoring. In the 21st century, with the development of hardware technology and machine visual technology, the monitoring industry has risen quickly in my country, such as public places, such as railway stations, shopping malls, campus, banks and other populations. It has been installed with a camera for security monitoring. Such measures not only guarantee the safety of the people's personal property, but also make a prominent contribution to safeguard social security and combating illegal crimes.

[0003] Most of the traditional monitoring system is a single-graphic camera. The main function is to play and st...
