Method and system for navigation of moving object in building based on video monitoring network

Abstract

The invention provides a method and a system for navigation of a moving object in a building based on a video monitoring network. The method comprises the following steps that a navigation server obtains final position information of the moving object and sends an image sample of the moving object to a network video monitoring system; the network video monitoring system captures a target video image according to the image sample, obtains current position information of the moving object according to the target video image and sends the current position information to the navigation server; and the navigation server generates global navigation path information according to a topological structure diagram of the building, the current position information and the final position information, sends a motion adjustment command to the moving object according to the global navigation path information and adjusts a motion direction of the moving object according to the position of the moving object until the moving object arrives at the destination. According to the method, the navigation server realizes navigation of the moving object in the building through the network video monitoring system, so that the moving object arrives at the destination quickly, and the intelligence level of the building is improved.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and system for moving objects in a building based on a video surveillance network. Background technique [0002] When people need to find a certain room in a building that they feel unfamiliar with, although the floor distribution diagram of the building can provide some guidance and help, it is poorly readable, not intuitive enough, and easy to forget. When a mobile robot in one room needs to reach another room in the building to complete the work, since the robot's vision sensor can only acquire local images around it, it cannot plan the correct global path. The above problems all require a real-time navigation technology that covers the whole building and can be solved. [0003] At present, people have done a lot of research on the navigation technology of outdoor mobile objects and have produced mature applications, such as road vehicle navigation base...
