Multi-camera intelligent monitoring method and device for monitoring moving target

Abstract

The invention provides a multi-camera intelligent monitoring method and device for moving target monitoring, and the method comprises the steps: enabling a monitoring system with m cameras (m is greater than 1), and monitoring whether a moving target exists in a target region or not during monitoring; if yes, the distance between the camera and the moving target is measured, the size of the movingtarget is calculated, and the information is transmitted to other cameras; each camera determines whether the camera is one of the first n (n is smaller than m) cameras closest to the moving target or not through a judgment algorithm according to the distance information, and if yes, a lens moving and focusing instruction is generated according to the position and size information of the moving target and executed; and when the moving target is moved out of the monitoring range, the camera returns to the initial working state. The device comprises a data acquisition module, a communication module, a processor module and an execution module. According to the invention, the camera can automatically complete a moving target monitoring task, and the robustness of the monitoring system is enhanced by adopting a switching network topology structure.

Description

technical field [0001] The invention relates to the field of monitoring, in particular to an intelligent focusing method and device for multiple cameras oriented to the monitoring of moving objects. Background technique [0002] In recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance has become an important part of the security system. Video surveillance is widely used in many occasions due to its intuitive, accurate, timely and rich information content, and has achieved remarkable results in public security prevention and control, urban management, and social governance. The camera is a data acquisition device for video surveillance, which completes the acquisition of video image signals. However, the camera in the traditional video surveillance system fixes the focal length by manual focusing during installation, so that the area that the camera can capture is also limited. For moving targets that ...
