摘要: 城市作为人类生活的重要聚集地,是三维GIS应用的主要领域。本文结合房屋的二维轮廓数据与屋顶的基本信息(倾斜角度、屋顶高度、纹理属性),以“骨架线提取-房屋模型构建”为框架,提出了一种基于多边形骨架线自动生成简单房屋模型的算法,详细描述了该方法的基本思想,并在试验结果的基础上证实了该算法的有效性。

Abstract: City, as an important place of human life, is the main field of 3D GIS application. A method to automatically generate the roof model based on straight skeleton of polygon is presented, with skeleton line extraction-housing model as the framework, based on 2D contour data of housing and the basic information of the roof (angle, roof height, texture attributes). At last the basic idea of the method is described and the effectiveness of the algorithm is verified by experimental results.

Key words: polygon, straight skeleton, roof model, visualization
