Multi-camera cooperative relay monitoring method based on known orbit

Abstract

The present invention discloses a multi-camera cooperation relay monitoring method based on known tracks. The method is applied to a track network connected and formed by a plurality of tracks, wherein a plurality of mobile nodes are randomly distributed in the track network, and each mobile node can move in any track and on any vertex, each mobile node can only monitor the targets at its edge and vertex, and each track of the network topological structure formed by the track network corresponds to one side of the network topological structure map and the junction points of the tracks correspond to the vertexes of the network topological structure map. The method reduces the cost of mobile monitoring, improves the monitoring range and security, and has a wide range of applications.

Description

technical field [0001] The invention belongs to the field of video monitoring, and specifically relates to a method for realizing continuous monitoring of mobile users through cooperative relay of multiple mobile cameras under the scenario of known track. Background technique [0002] In recent years, with the development of video processing technology and network technology, video surveillance technology has been widely used in people's life and work. Video surveillance is used to collect data and monitor suspicious behaviors and events. The "9.11" incident in the United States and the British subway explosion and other terrorist attacks have made the demand for video surveillance systems all over the world unprecedentedly high. With the strong growth of global demand for video surveillance applications, the upsurge of the development of the Internet of Things has greatly matched and expanded the research and development space of video surveillance.

Problems solved by technology

However, this method has the following defects: 1. The monitoring range of a single deployed monitoring node is limited; 2. A large number of monitoring nodes (i.e., monitoring cameras) are required to achieve full coverage of the monitoring area, and the resource cost is high; 3. Fixed deployment Nodes are easy to be "stepped on" in advance, and then deliberately avoided by criminals, which has poor security

In the mobile video surveillance system, due to the mobile monitoring, the monitoring range is larger and more thorough, and the number of nodes to be deployed will be greatly reduced; and the movement of the camera is flexible and changeable, and it is impossible to predict its position at the next moment in advance. And constantly change the monitoring angle to carry out all-round and multi-angle monitoring, making criminal suspects hard to guard against

At present, mobile video surveillance is limited to restrictive mobile surveillance, which means that although the surveillance camera can be moved, the movement route is restricted by the track. The movement track of the surveillance camera is single and fixed, and the next target location of its movement can be predicted; for example, In the monitoring system of the museum, the mobile camera is generally installed on the track of the ceiling. In this situation, the mobile camera can only move along a single track. There are still dead spots in the monitoring area, the monitoring track does not change, or there are still "stepping on the spot" In addition, there is currently a mobile monitoring method that only considers the free movement of mobile nodes, and does not take into account the limitations of the actual environment
