Design And Realization Of3D Visualization System Of Civil Defense

The rapid development of social economy, urbanization is accelerating, the scale andutilization of civil air defense engineering also develope rapidly.At the same time, theevolution of modern science and technology and the rapid development of information warfarealso put forward higher requirements of construction, management, operation, maintenanceand use of civil air defense.Because of the particularity of the underground civil air defenseengineering, the3D visualization of civil air defense is a new way to use and manage civil airdefense which combines with geographic information system,3D visualization technology andnetwork transmission technology.The research realizes the production and network release of civil air defense engineering3D visualization scene, using the Internet of things, GIS and3D visualization technology,based on the remote sensing image, DEM,3D model and the civil air defense engineeringbusiness data, with the aid of the Skyline technology platform for the global leading. At thesame time, according to the principle of the system development, combined with therequirements of3D visualization of construction of civil air defense engineering, we determinethe technical route of this system is B/S structure, using J2EE system design and Skyline3Dsoftware Terra Explorer Pro SDK library for the secondary development of3D GIS on theplatform of Java2. The main achievements are as follows:(1)Production and network release of civil air defense engineering and3D visualizationsceneFusion of remote sensing image data and DEM data, generate the civil air defenseengineering of3D terrain model; the network publishing of terrain model, vector data and3Dmodel; set network after the release of the terrain model, vector data and3D model, finallyfinished the production of civil air defense engineering3D visual scene, for WEB procedurecall.(2)Integrated the multi-source information of civil air defense With the help of Skyline3D visualization platform, realized the integrated display ofimage data, the civil air defense engineering elevation data, vector data and attributedata,which can offer a better serve to civil air defense management.(3)Real time monitoring of civil air defense engineering internal environment andfacilitiesWith the help of network transmission technology, sensing device is placed in keyposition in civil air defense works, the program will monitor the data access system, real-timemonitoring of underground environment quality and equipment running status, realize theintelligent management of civil air defense engineering.Finally, the paper takes Beijing city civil air defense engineering visualization as anexample, on the development of the system are discussed, which performances good.
