Video geographic information system and method for urban areas

Abstract

The invention discloses a video geographic information system and method for urban areas. The system comprises a video acquisition Agent, a video server and a geographic information system (GIS) positioned in the server, wherein the Agent is composed of a video transmission module and a video image projection transformation module; and the video server is composed of a video image and map registering module, a video projection and geographic information integrating module and a dynamic video GIS display module. The system of the invention is independent, data of the system comes from video monitoring cameras in the urban area, the instantaneity is high, lots of cameras can be simultaneously connected to the system, a lot of continuous monitoring data can be simultaneously read from one map, and visual whole-city running states and a target continuously searching and tracking service are provided for the city managers and decision makers.

Description

technical field [0001] The present invention relates to a video surveillance system and a geographic information system and method, in particular to an intelligent video geographic information that integrates metropolitan-oriented video surveillance and a GIS system for real-time monitoring of a large area under the same coordinate system and the same viewing angle (GIS) system, which belongs to the field of computer vision. Background technique [0002] With the development of the world economy and the popularization of video surveillance, the demand for computer vision in various applications is also increasing, and computer vision has received more attention. Computer intelligent video surveillance is an emerging application direction and a frontier subject that has attracted much attention in the field of computer vision. At the same time, geospatial expression is also an important content in the field of geographic information science, and it is also a major challenge ...
