doi:10.13474/j.cnki.11-2246.2018.0187

Abstract

Abstract: 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.

Key words: point cloud, ancient buildings, triangular mesh model, entity model, informational management
