摘要
通过三维激光扫描、手持式SLAM扫描、机载LIDAR、倾斜摄影测量等多种测量方式对历史建筑进行数据采集,并对空地多源数据进行融合,阐述多源点云数据融合方法及精度情况。以浙江省宁波市某历史建筑的点云融合为例,概述了空地多源数据融合建模在历史建筑数字化营造中的应用,并结合实例进行了多种空地多源数据融合建模方式的精度评比。
Data collection of historical buildings is carried out by means of three-dimensional laser scanning,hand-held SLAM scanning,Airborne Lidar,oblique photogrammetry and so on,the method and accuracy of multi-source point cloud data fusion are described.Taking the point cloud fusion of a historical building in Ningbo,Zhejiang Province as an example,this paper summarizes the application of multi-source data fusion modeling of open space in the digital construction of historical buildings,and analyzes the accuracy of various modeling methods for multi-source data fusion of open space and ground with examples.
