基于多种三维激光点云获取技术的历史建筑测绘研究

Research on Historical Building Surveying and Mapping Based on Multiple 3D Laser Point Cloud Acquisition Technologies

三维激光点云获取技术能快速、精确、多方位获取物体的三维信息,为历史建筑测绘提供新思路。本文从三维激光点云获取技术特点及测绘历史建筑的适用性出发,介绍点云数据采集、多种数据融合处理的流程。以常州市历史建筑普查为例,论述常州市历史建筑三维激光点云获取到处理关键技术,点云成果精度符合历史建筑测绘要求,也为后续历史建筑保护和修缮提供了数据支撑。

3D laser point cloud acquisition technology can quickly,accurately and multi-directional acquisition of 3D information of objects,providing a new idea for surveying and mapping historical buildings.Based on the characteristics of 3D laser point cloud acquisition technology and the applicability of surveying and mapping historical buildings,this paper introduces the process of point cloud data acquisition and multiple data fusion processing.Taking the historical buildings survey in Changzhou as an example,this paper discusses the key technologies of obtaining and processing the 3D laser point cloud of historic buildings in Changzhou.The accuracy of the point cloud results meets the requirements of historical building mapping and provides data support for the subsequent protection and repair of historic buildings.
