Abstract

The invention provides a rapid video tracking method based on road network data. The method comprises the following steps of S101, establishing a geographic information database of video monitoring, wherein the geographic information database includes a road-network geographic information database and a camera information database; S103, designing a space algorithm, wherein the space algorithm includes a video monitoring scope algorithm and a video retrieval algorithm based on a path; and S105, using the space algorithm to find a path which a target passes through in the road-network geographic information database, retrieving the camera information database, and predicting the path of the target. According to the rapid video tracking method based on road data, based on a geographic information system, the rapid video tracking method and a system based on the road network data are constructed, a monitored video can be rapidly retrieved, an escape route of the target can be rapidly predicted and seamless tracking of the target is realized.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video fast tracking method based on road network data. Background technique [0002] Safe City is a key business system in the construction of my country's e-government in recent years. The urban alarm and monitoring system is the core of the construction of a safe city and an important part of the social security prevention and control system. With the rapid development of social economy, the social security situation is becoming more and more complicated, and it is directly related to the development of the whole city. City video surveillance system is an important means. [0003] The biggest difference between GIS and other systems is the ability to store and analyze spatial data. For the video surveillance system based on the geographic information system, when a major case or emergency occurs, it can accurately determine the alarm point and the on-site location...
