摘要
提出了一种以扫描点云为数据源的古建筑综合建模方法。针对复杂部位,采用Delaunay四面体剖分算法构建三角网模型,而对于规则部位,以点云为参考直接构建实体模型,并借助建筑信息模型的特点,实现了古建筑模型的信息化管理。试验表明本文的三维重建方法能以较小的数据量重建出古建筑的精细模型,本文的信息化管理方法可以分阶段对古建筑的几何和属性信息进行持续高效地管理。
This paper puts forward a comprehensive modeling method for ancient buildings based on scanning point cloud.For irregular or complex parts, triangular mesh models are constructed by Delaunay triangulation.On the contrary, for relatively simple and organized features,the entity models are directly built under the reference of the point cloud. With the advantages of the BIM, informational management of the models of ancient buildings are realized.Experiments show that the proposed 3D reconstruction method for ancient buildings can reconstruct a detailed model with smaller data, and the informational management method can provide sustainable and efficient management of ancient buildings＇ geometry and attribute information in stages.
