Pedestrian abnormal behavior detection method based on human skeleton

Abstract

The invention provides a pedestrian abnormal behavior detection method based on a human skeleton, and the method comprises the following steps: 1, carrying out the pedestrian detection of an image, carrying out the framing through a detection frame, and obtaining a pedestrian detection frame; 2, extracting human skeleton information from the pedestrian detection box obtained in the step 1 to obtain a human skeleton information picture, and performing background removal preprocessing on the picture; and 3, performing pedestrian abnormal behavior detection on the preprocessed human body skeletoninformation picture in the step 2 by using a multi-scale information fusion recognition network based on residual errors to obtain a four-dimensional vector corresponding to four types of actions ofhuman body abnormal behaviors; according to the method, the skeleton information and the multi-scale information are effectively utilized, the detection accuracy of the algorithm is greatly improved,the robustness of the algorithm is enhanced, and the application of the algorithm is not limited by scenes.

Description

technical field [0001] The invention belongs to the field of intelligent video monitoring, and in particular relates to a method for detecting abnormal behavior of pedestrians based on a human body skeleton. Background technique [0002] In recent years, with the development of computer technology and the increase of security requirements, intelligent video surveillance has increasingly become a research hotspot in the field of computer vision. It is very different from traditional monitoring systems in terms of intelligence. The traditional monitoring system uses cameras to record, and people are the main body to monitor and identify video content. This method not only consumes a lot of manpower and material resources, but also has a very serious problem: when people are engaged in the same job for a long time, it is easy to Fatigue and ignore some details of the information. The intelligent video surveillance system endows the machine with the ability to make autonomous d...
