【摘要】：随着世界城市化进程的飞速发展，越来越多的军事行动将集中在城市，城市将成为21世纪的主战场。城市作战是目前各国关注的重点，获取战场信息优势，争取战场环境透明也成为各国测绘部门的当务之急。城市战场环境建设在信息技术的推动下孕育新的内涵，应用虚拟现实技术研究战场环境成为当前研究热点，作为虚拟城市战场环境的基础，城市战场环境三维建模的方法显得越来越重要。本文对城市战场环境的构成和城市空间信息的内容进行了深入分析，从构建三维城市战场环境的应用出发，提出了三维城市战场环境需要表达的内容：探讨了城市三维建模的相关技术，系统研究了城市空间信息的获取和数据模型。在此基础之上，研究了城市战场环境三维建模的方法，探讨了GIS空间分析在三维城市战场环境空间分析中的应用，提出了三维城市战场环境空间分析的分类体系，实现了基于DEM的地形分析，市区交通分析，，雷达探测范围分析及分析结果可视化，基于属性数据库实现了三维图形和属性数据的双向查询等分析功能。设计并实现了一个“城市战场环境三维建模与空间分析”原型系统。
[Abstract]:With the rapid development of urbanization in the world, more and more military operations will be concentrated in cities, which will become the main battlefield in the 21st century. Urban warfare is the focus of national attention at present. Obtaining battlefield information superiority and striving for battlefield environment transparency also become the top priority of surveying and mapping departments in various countries. Under the promotion of information technology, the construction of urban battlefield environment has given birth to new connotations. The application of virtual reality technology in battlefield environment research has become the current research hotspot, as the foundation of virtual city battlefield environment. The method of 3D modeling of urban battlefield environment is becoming more and more important. This paper deeply analyzes the constitution of urban battlefield environment and the content of urban space information, and starts from the application of constructing 3D urban battlefield environment. This paper puts forward the contents that need to be expressed in 3D urban battlefield environment. The related techniques of 3D urban modeling are discussed, and the acquisition of urban spatial information and the data model are systematically studied. On this basis, the 3D modeling method of urban battlefield environment is studied, the application of GIS spatial analysis in 3D urban battlefield environment spatial analysis is discussed, and the classification system of 3D urban battlefield environment spatial analysis is put forward. Terrain analysis based on Dem, urban traffic analysis, radar detection range analysis and visualization of analysis results are realized. Based on attribute database, bidirectional query of 3D graphics and attribute data is realized. A prototype system of "3D modeling and spatial analysis of urban battlefield environment" is designed and implemented.
