摘要
提出了顾及多面片建筑物模型拓扑关系的边界提取方法。针对多面片建筑物的特点并基于最小二乘法,设计了一套适合多面片建筑物的边界规则化方法,并生成了3维建筑物模型。实验证明,本文方法对于多面片建筑物模型的3维自动重建都是可行和有效的。
This paper presents an edge extraction method considering the Topo-relation of multi-parcel building model. Considering features of multi-parcel building and using the Least Square Refine method, a suit of edge regularization method suiting for multi-parcel building model are designed, and 3D building models are generated. The experiment indicates the method to reeonstruct multi-parcel building model automatically is feasible and available.
