Cross-camera suspicious pedestrian target tracking system for rail transit panoramic monitoring

Abstract

The invention provides a cross-camera suspicious pedestrian target tracking system for rail transit panoramic monitoring, which comprise a module for suspicious pedestrian target detection in single-camera rail transit video, a module for suspicious pedestrian target tracking in single-camera rail transit video, a module for target matching among multiple cameras, and a module for target transferring among multiple cameras, and is characterized in that the module for suspicious pedestrian target detection in single-camera rail transit video is used for recognizing a moving suspicious pedestrian in the single-camera rail monitoring video; the module for suspicious pedestrian target tracking in single-camera rail transit video is used for marking a moving suspicious pedestrian target in the single-camera rail transit video in real time; the module for target matching among multiple cameras is used for performing feature matching on the target pedestrian in the current monitoring camera and the pedestrian target in monitoring video of associated cameras; and the module for target transferring among multiple cameras is applied to a condition of a multi-camera visual field region, predicts a moving track of the suspicious pedestrian according to a matching result of the target between adjacent cameras, the moving direction of the pedestrian in the single camera and the topological structure of the cameras, and judges a coverage area in which the suspicious pedestrian target steps after walking out of the current region.

Description

technical field [0001] The invention belongs to the field of computer vision, and in particular relates to a cross-camera suspicious pedestrian target tracking system for panoramic monitoring of rail transit. Background technique [0002] With the development of society, video surveillance plays an increasingly important role in ensuring public safety and maintaining social stability. At present, a large number of surveillance cameras are installed in major public places across the country. According to statistics, from 2010 to 2014, the total number of cameras in my country has increased by 20% per year. In recent years, with the development of the transportation industry, rail transit has become more and more popular, which not only greatly facilitates the travel of citizens, but also facilitates some people who violate the law and discipline. Rail transit has become the first choice for many criminals due to its fast, concealed, and crowded characteristics. Therefore, i...

Problems solved by technology

As far as the current situation of intelligent monitoring is concerned, there are two deficiencies: on the one hand, the shooting area based on a single camera is limited, and it cannot achieve long-term continuous and effective tracking of moving targets; on the other hand, the range of intelligent monitoring is very wide, but the coverage of the camera itself However, the field of view is limited; moreover, due to economic reasons, the number of cameras is limited, so that the cross-shooting area in rail transit is almost zero

In view of these two major problems, continuous and effective monitoring of large-scale scenarios cannot be achieved
