点云建模技术在部件级古建筑构件三维可视化中的应用
Application of point cloud modeling technology in three-dimensional visualization of ancient building components
摘要
Abstract
The protection of ancient buildings is an important issue in the inheritance and development of traditional culture.The construction of precise three-dimensional(3D)models of ancient buildings plays an irreplaceable role in the protection of ancient buildings.Ancient wooden buildings have complex structures,and it is difficult to obtain data of building structure details and models and construct models.To address these issues,this paper processed the obtained multi-element point cloud data by means of point cloud coordinate transformation,registration,and segmentation while combining a stationary 3D laser scanner with a handheld 3D laser scanner,so as to obtain the structural data of abutment,wooden frame,and roof components of ancient wooden buildings.On this basis,the 3D model of each component of ancient wooden buildings was constructed,and the ancient buildings with complete structures were modeled by assembling the models.By taking Langrun Garden as an example,this paper constructed a 3D model of three buildings in the center,which complied with the building structure with high accuracy.Therefore,it can be proven that the application of 3D laser scanning technology in ancient building surveying and mapping is feasible,featuring low cost,high efficiency,and high precision,and it can provide basic data for the maintenance and repair of ancient buildings,as well as the reconstruction of antique buildings and serve as a complete spatial information basis for the establishment of a comprehensive system for the protection of cultural relics.关键词
