Title:
VIOLENT BEHAVIOR DETECTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/051547
Kind Code:
A1
Abstract:
A violent behavior detection method, comprising: obtaining a scene image by means of a camera; inputting the scene image into a feature pyramid network, and obtaining a target human body from the scene image; performing human body pose estimation on the target human body by using a cascaded pyramid network to obtain a human body pose estimation result, wherein the cascaded pyramid network comprises a GlobalNet network and a RefineNet network; and matching the human body pose estimation result with violent behavior human body poses stored in a database so as to determine whether a violent behavior exists in the scene image according to a matching result, and classifying the violent behaviors. Embodiments of the present application further provide a violent behavior detection system, a computer device, and a readable storage medium. By means of the embodiments of the present application, human body key points can be successfully positioned, the identification accuracy is greatly improved, and a calculation amount is reduced.
