摘要
本文对虚拟现实技术(VR)在基于GIS的城市消防指挥系统中的应用进行了研究,解决了在系统实现过程中遇到的:基于城市电子地图的海量建筑物三维建模:多源数据的融合和虚拟场景的表现与控制等关键技术。并在此基础上开发了综合运用GIS和VR的消防指挥系统。文中介绍了这些关键技术的解决方案和实现过程。
The research on fire fighting commanding system based on geography information system (G1S) and virtual reality (VR) is carried out. Some key problems are solved by the authors. It means that a huge amount of data is treated while the 3D modeling of a lot of buildings in urban area. The other two problems are the amalgamation of data from variable sources and the visualization and controlling of virtual world. At last, a fire fighting commanding system, in which GIS and VR are integrated and used, is developed. It is found that the solutions and development details of the problems are presented in the paper.
