摘要
分析了建筑物的结构 ,提出了对简单建筑物半自动提取的策略以及对复杂建筑物顾及其空间三维拓扑结构的建模模型 ,用实例论证了模型的正确性和高效性。
This paper firstly presents state-of-the-art of 3D modeling of building and analyses the structure of 3D building, then gives a method of 3D building classification. Finally, this paper presents a strategy to the semi-automation extraction of complex building and puts forward a topological data model of 3D building, and 3D modeling of building is achieved.
