Monitoring system using multiple pick-up cameras

Abstract

Provides a security solution that reduces the burden on surveillance personnel and is not troublesome for users in a system that monitors a target space with multiple cameras. Use image recognition technology to extract moving objects from images captured by each camera, and compare them between cameras. Then, the moving path of the moving body is obtained, and whether or not the restricted area is entered is judged, and an alarm is displayed to the supervisor. Whether you have permission to enter restricted areas is judged by individual-specific institutions such as combination card authentication and camera monitoring and tracking. In addition, by analyzing the moving track and path to determine whether it is an unknown person, an alarm warning is also issued. As a basis for the above-mentioned processing, a monitoring space database is built, and the processing is carried out in transit.

Description

technical field [0001] The present invention relates to a monitoring system for identifying, comparing or tracking photographed moving objects, such as people and cars, through multiple cameras installed in the object space. Background technique [0002] In order to cope with social chaos such as the low crime reporting rate, and to maintain and improve the security level, the number of cameras installed to monitor unknown persons and unknown vehicles has been increased. In the initial stage of introduction, surveillance personnel visually observe the images captured by the camera in the surveillance room, dispatch police or guards to the scene under abnormal circumstances, and store the images in the video recorder, which is useful for searches after crimes occur, etc., using direct and indirect It is helpful to prevent crimes in advance and respond to them afterwards. However, the rapid increase in the number of installations, not only the increase of cameras, but also th...

Problems solved by technology

In this way, in order to ensure the level of security, it is necessary to restrict access by adding surveillance cameras and locking. However, since excessive system introduction will lead to cost increases and inconvenience to users, it is necessary to be able to set Highest level of safety, flexible combined system

[0005] According to the requirements for the above-described system, well-known techniques are studied. As described in Patent Document 1, the image of the moving object after comparison is displayed on the monitor using the overall feature information, or the method of specifying the moving object to be tracked by the monitor In this case, it is necessary for the surveillance personnel to judge whether it is a suspicious behavior or not, and it is not enough to reduce the monitoring burden by inferring the moving path of the target moving object in the surveillance space.

In addition, there is no unspecified majority, and when entering a specific area (such as a hallway in a building, etc.), it is unrealistic to follow all personnel in terms of the number of appearances, and it is limited to those that can be applied. scene
