摘要
三维激光扫描技术以其高精度、全自动、适合各种复杂测量环境的特点,已成为当前空间信息数据获取的重要途径。以某钢铁厂防空洞为研究对象,阐述了三维激光扫描仪快速获取防空洞表面的激光点云数据,对多站点云数据进行拼接去噪配准后,获得整个防空洞内部的完整激光点云数据。结果表明,利用三维激光扫描仪获取该防空洞点云数据,构建防空洞的三维模型,据此计算防空洞体积具有较高的精度,可以代替传统全站仪断面法测量。
Three-dimensional laser scanning technology has become an important way to obtain spa-tial information data because of its high precision,automatic and suitable for various complex measurement environments.Taking the bomb shelter of a steel plant as the research object,this paper expounds that the 3D laser scanner can quickly obtain the laser point cloud data on the surface of the bomb shelter.After splic-ing and denoising the multi-site cloud data,the complete laser point cloud data inside the whole bomb shel-ter are obtained.The results show that the 3D laser scanner is used to obtain the point cloud data of the bomb shelter,and the 3D model of the air-raid shelter is constructed.Based on this,the calculation of the volume of the bomb shelter has high accuracy and can replace the traditional total station section method.
