摘要:针对当前数字城市三维精细模型建设方法的特点和成本,该文提出一种城市三维快速建模方法,作为对精细三维模型建模的补充。该方法的主要思路和技术特点是充分利用现有城市测绘信息资源的前提下,通过研究各种模型要素的特点,设计出一种自动化程度非常高的技术来实现城市建筑的三维快速建模。该方法保证城市三维模型的逼真效果和浏览速度,极大的提高了三维城市建模的效率,在城市三维建模中具有很好的推广和应用价值。

ABSTRACT: Just as features and cost for city construction method of the current three-dimensional detailed model, this paper presents a three-dimensional modeling of urban rapid method which can be regarded as plement to the three-dimensional modeling. Studying the characteristics of the various elements of the model and using the existing urban mapping information of resources, this approach devises a very high degree of automation technology to achieve three-dimensional fast modeling of urban architecture. This approach guarantees realistic effects and browsing speed of three-dimensional model, which greatly improves the efficiency of the 3D city modeling, with good promotion and application value in three-dimensional modeling of the city.
Keywords: City 3D modeling; 3D GIS; Fast modeling.
