一种结构化的三维建筑房顶分类与识别方法

摘要

Roof is an important part of 3D building model. The recognition of building roof is the preconditionin of 3D building generalization and spatial distribution pattern cognition of city building. Characteristic of building roof is analyzed in this paper and buildings are classified by different roof type. Different types of roof are described by a structured method, then surface of building roof is picked up and roof types are recognized. Experiment is done to prove that proposed approach is of accuracy and may fulfill with the deep application requirement.%房顶是三维建筑的重要组成部分，房顶结构的识别是三维建筑综合算法实现和进行城市建筑空间分布模式分析的基础。分析了建筑房顶结构特点，提出了一种三维建筑分类的实用方法，针对不同房顶类型设计了相应的结构化表达方法，在此基础上提出了三维建筑房顶面信息提取算法，并进一步实现了房顶类型的识别。实验证明，该方法识别的准确性较高，能够满足进一步应用的需求。
