Integration and application of video surveillance system and 3DGIS

With the rapid development of spatial information technology, the combination of video surveillance system with GIS platform that has powerful spatial analysis capabilities has become an important trend of video surveillance system. Based on Video on Terrain technology of the software Skyline, this paper puts forward an integration solution of 3DGIS and video surveillance system that sets videos in the three-dimensional spatial scene, and designs the architecture of the integrated system. It also discusses the key technologies such as video data transmission and coding, alarm processes of video surveillance, network analysis and database structure, and introduces in details the process of creating the three-dimensional scene. Finally, an example of the integrated system of video surveillance and 3DGIS is given and advantages of it are analyzed.
