Pedestrian head-shoulder detection and appearance capturing method based on main and subsidiary cameras

Abstract

The invention discloses a pedestrian head-shoulder detection and appearance capturing method based on main and subsidiary cameras. A main and subsidiary camera system is constructed, a self-made calibration board is utilized to calibrate the linkage between the main and subsidiary cameras, an improved ViBe algorithm is adopted to detect a moving object area in a scene, the problem of dead zones occurring in a traditional ViBe algorithm is solved, a pedestrian head-shoulder detection algorithm based on two stages is adopted to detect the head and shoulders of a pedestrian of the moving target area, and the problem that a traditional head-shoulder detection algorithm is high in false detection rate is solved. The pedestrian head-shoulder detection and appearance capturing method has the advantages that the moving pedestrian in the monitoring area can be detected in real time, and the distinct appearance of the moving pedestrian is obtained.

Description

technical field [0001] The invention relates to a pedestrian head and shoulder detection and appearance capture method based on a master-slave camera, and belongs to an improved method for a moving target detection algorithm and a pedestrian head and shoulder detection algorithm. Background technique [0002] During the construction of the "Safe City Project", video surveillance in public areas is becoming more and more important. The widespread application of video surveillance systems has brought great help to the criminal investigation work of the public security system, and it can even be said that it has changed the way the public security system handles cases. For example, the "Zhou Kehua armed robbery case" that was successfully solved in 2012 was solved by using a large number of surveillance videos of the crime scene for analysis and detection. Nowadays, public places such as schools, supermarkets, and stations have installed a large number of monitoring camera equ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a pedestrian head and shoulder detection and appearance capture method based on the master-slave camera, build a master-slave camera system, use a self-made calibration board to calibrate the linkage between the master-slave cameras, and use the improved ViBe algorithm to realize the scene. The detection of the moving target area overcomes the problem of "dead zone" in the traditional ViBe algorithm, and adopts a two-stage pedestrian head and shoulders detection algorithm to detect the head and shoulders of pedestrians in the moving target area, overcoming the high false detection rate of the traditional head and shoulders detection algorithm The problem
