| 摘 要： | 人防工事狭长且内部环境复杂,对其保护利用需要提供丰富多样的基础资料和成果。三维激光扫描技术突破了传统单点精确测量的局限,可以大面积地获取被测对象表面的三维坐标数据,具有连续、快速、非接触、自动、全天候工作等优势。本文以某段人防工事为例,研究了三维激光扫描的工作流程,并以点云数据为基础进行三维模型的重构和测绘图的制作,完成对点云质量的分析评价。

| Abstract: | Air defence fortificationsis is long and the internal environment is complex. Three dimensional laser scanning technology has broken through the limitations of traditional single point precise measurement. 3D laser scanning can measure the three dimensional coordinate in large area, and break through the limitations of traditional single point precise measurement. It has the advantages of continuous, fast, non-contact, automatic and all-weather work. The article takes a section of air defence fortifications as an example, studies the work flow of 3D laser scanning, makes model reconstruction and surveying and mapping based on point cloud data, completes the analysis and evaluation of the quality of the point cloud. |
