Abstract

The present invention provides a reconstruction method of human posture based on the geometrical skeleton, including:determining human skeleton pattern; obtaining 3D human skeleton pattern, pre-processing image; obtaining bianry image of separation of the background and the human; acquiring human geometrical skeleton; obtaining linear geometrical skeleton; labelling articulare of the start frame; bonding the manual labelling articulare on the geometrical skeleton, shortening the initial error; tracing the articulare by light stream method; obtaining the new position by the light stream method; processing error judgement and position correction to the new articulare obtained by the trace with the combined geometrical skeleton; processing line correction calculated by the light stream method; re-constructing the human posture; converting the two-dimensinal coordinate of the articulare to the 3D skeleton pattern by the parameter evaluating method of the proportion orthogonal projection model. The invention improves accuracy of the posture reconstruction, obtaining a high processing efficiency, capable of processing stable and effect human posture reconstruction in the intelligent video monitor system.

Description

technical field [0001] The invention belongs to the technical field of intelligent video monitoring, and in particular relates to a method for reconstructing a human body posture based on a geometric skeleton. Background technique [0002] In an intelligent video surveillance system, human pose reconstruction is the second stage. Through human body posture reconstruction, the posture of the human body in the surveillance video can be determined, and the degree of danger of the posture can be judged by retrieving the human body posture in the posture database, so as to take certain early warning measures. Human pose reconstruction is a basic problem in computer vision and pattern recognition, and it is applied to many fields, such as video surveillance, sports analysis, and auxiliary clinical medical diagnosis. Effective human pose reconstruction can expand the functions of the video surveillance system and enable computers to learn, analyze and understand human actions and ...
