摘要
三维激光扫描技术已成为建筑物三维模型构建的重要测量手段,其三维激光点云数据获取主要通过架站式或手持移动式三维激光扫描仪。本文简要介绍了两种三维激光扫描仪的工作原理及三维激光点云的数据处理流程,并以项目工程实例详细阐述了基于三维激光扫描技术的建筑物三维模型构建方法,并以解析法实测部分建筑物角点进行精度验证。结果表明该方法能满足室内空间大且场景复杂建筑物的三维模型构建。
3D laser scanning technology has become an important means of measurement for 3D model construction of buildings,and its 3D laser point cloud data is mainly obtained through the standing or handheld mobile 3D laser scanner.This paper briefly introduces the working principle of two 3D laser scanners and the data processing process of 3D laser point cloud,and expounds the construction method of building 3D laser scanning technology based on the project engineering example,and verifies the accuracy of some building corner points by analytical method.The results show that this method can meet the 3D model construction of buildings with large indoor space and complex scenes.
