Method and system for pedestrian monitoring and behavior recognition

Abstract

The invention relates to the related technical field of behavior analysis simulation, and discloses a method of pedestrian monitoring and behavior recognition. The method comprises the following steps: S1, video acquisition is carried out on a somatosensory video device, and a corresponding depth image data stream and a color image data stream are acquired; S2, a system spatial coordinate-ground coordinate conversion matrix is calculated, ground projection is carried out on the depth information, a single human body is effectively segmented in the case of occlusion entering of multiple bodies, and non-human body targets are eliminated according to the ground projection; S3, three-dimensional depth information of a target body is acquired, and three-dimensional coordinates of 15 joints of the human body are positioned according to the depth information; S4, a human body three-dimensional model is built; S5, motion parameters of the human body are acquired; and S6, behavior features of the human body are acquired, and a processing result is fed back. The method and the system of the invention have the beneficial effects that the mounting is convenient and flexible; the pedestrian in-out conditions in a specified area is monitored and detected in a real time mode; and tracking and behavior recognition is carried out on a pedestrian entering.

Description

technical field [0001] The invention relates to the technical field of behavior analysis and simulation, in particular to an Xtion-based method and system for pedestrian monitoring and behavior identification in a bank lobby. Background technique [0002] At present, with the expansion of banking business, people are more and more concerned about the safety measures and protection in the bank. How to effectively prevent and avoid emergencies in the bank lobby is an urgent problem to be solved. Most of the current video surveillance in banks does not have intelligent analysis functions, cannot respond to emergencies, and cannot be quickly checked after an event occurs, which has caused great trouble to the security of the bank. [0003] Compared with color cameras, somatosensory cameras can obtain more useful information and expand two-dimensional plane images to three-dimensional. The somatosensory camera was first applied to the game field, using the movements of the body ...
