【摘要】：在计算机与信息化科技日新月异的背景下,三维仿真系统逐渐得到普遍应用,它不但被应用于城市的规划与管理中,而且还在城市的辅助决策工作上起到一定的作用。文章围绕着出现于三维城市建设工作里的数据机构与标准为中心,并建立在三维数字城市建设与实际应用的基础上,展开对于城市三维模型数据标准的制定与应用的论述。文章首先围绕着所要研究的目标展开分析与探索,对于城市地下与地表的空间数据进行了分析与总结;紧接着开始围绕着软件与硬件体系、城市数据模型以及系统功能等方面展开结构的设计工作。此外,文章还对存在于现代社会里的可视化模型进行了论述,并进一步做出了关于城市地物数据结构的解释,从而详尽地论述了文章里所采用的模型。最后文章对于出现于城市建模里的技术要领作了具体的总结,并建立在一个实际例子的基础上使文章所研究的技术与思想得到了认证。文章经过研究证实,构建城市三维仿真系统有利于开展城市其他方面的工作,如旅游外宣、城市规划以及智能交通等,而且还可以更好地服务于现代信息化社会。
[Abstract]:With the rapid development of computer and information technology, 3D simulation system has been widely used. It is not only used in urban planning and management, but also plays a certain role in urban decision-making. This paper focuses on the data institutions and standards that appear in the construction of 3D cities, and discusses the formulation and application of the data standards for 3D models on the basis of the construction and practical application of 3D digital cities. Firstly, the paper analyzes and explores the spatial data of urban underground and surface, and then begins to analyze and summarize the spatial data of urban underground and surface. Then, it begins to focus on the software and hardware system. The design of urban data model and system function is carried out. In addition, the paper also discusses the visualization model existing in modern society, and further explains the data structure of urban features, so as to discuss the model used in this paper in detail. Finally, the technical essentials of urban modeling are summarized, and based on a practical example, the techniques and ideas studied in this paper are verified. Through the research, it is proved that the construction of the city 3D simulation system is beneficial to other aspects of the city, such as tourism publicity, urban planning and intelligent transportation, and can better serve the modern information society.
