Problems solved by technology

At present, video monitoring through cameras mostly relies on video analysis methods. Video analysis needs to consume large bandwidth traffic and generate high traffic costs; if monitoring video is used when the network is busy, it needs to occupy a lot of network resources, and video Screen freezes, jitters and delays cannot meet the viewing and operation requirements of video surveillance and affect the monitoring effect

Abstract

The embodiment of the invention provides a method and system for judging whether a camera is abnormal or not. The method comprises the steps that: basic features of a plurality of cameras and an association relation among the plurality of cameras are obtained, the basic features of the plurality of cameras comprise at least one of camera flow change, camera angle data, camera zoom data and camera white balance data, and the association relationship among the cameras comprises at least one of relative angles between the cameras and distances between the cameras; the basic features of the plurality of cameras and the association relation among the plurality of cameras are input into a judgment model, wherein the judgment model is a GNN model; and whether the plurality of cameras are abnormal is determined based on an output result of the judgment model.

Description

technical field [0001] This specification relates to the communication field, and in particular to a method and system for judging whether a camera is abnormal. Background technique [0002] Video surveillance is an important part of the security system. With the rapid development of security, there are more and more applications of video surveillance. At present, video monitoring through cameras mostly relies on video analysis methods. Video analysis needs to consume large bandwidth traffic and generate high traffic costs; if monitoring video is used when the network is busy, it needs to occupy a lot of network resources, and video Screen freezes, jitters, and delays cannot meet the viewing and operation requirements of video surveillance and affect the monitoring effect. [0003] Therefore, in order to perform video surveillance efficiently and at low cost, there is an urgent need for a method and system for judging whether a camera is abnormal.
