Document Type and Number:
WIPO Patent Application WO/2022/067606
Kind Code:
A1
Abstract:
A method and system for detecting an abnormal behavior of a pedestrian, and a terminal and a storage medium, which belong to the technical field of pedestrian mode recognition. The method comprises: extracting human skeleton key point information of each pedestrian from all video frames under multiple monitoring videos, and acquiring three-dimensional space coordinate information of each skeleton key point under the same coordinate system (S20); constructing a pedestrian skeleton key point space-time diagram in a cross-video scenario according to three-dimensional space information of each skeleton key point (S30); and inputting the human skeleton key point space-time diagram of each pedestrian into a space-time diagram neural network model, performing calculation to obtain an abnormal score value of each pedestrian, and determining whether a pedestrian behavior is abnormal according to a set abnormal score value threshold (S40). By means of the method, the loss of camera projection information can be reduced, the capability of detecting details of a pedestrian action can be improved, and an abnormal behavior of a pedestrian can be more effectively recognized.
