摘要
轨道交通的日益增多以及其运行速度的有效提升,无疑对轨道建设工程的质量提出了更高水平的要求。基于此,提出三维激光扫描技术支持下的地铁工程测量实施方法。在地物的提取与绘制基础上,完成点云数据采集,使得隧道中心线自动生成,进而实现精细三维建模。根据实验结果的对比可知,本文提出的地铁工程测量实施方法相比于传统方法而言,在测量精确度上占有较大优势,实验证明,本文方法具备较高的实用性和有效性。
The increasing number of rail transit and the effective improvement of its running speed undoubtedly put forward higher requirements for the quality of rail construction projects.Based on this,a method of metro engineering measurement supported by 3D laser scanning technology is proposed.On the basis of ground object extraction and rendering,point cloud data collection is completed to automatically generate the center line of the tunnel,and then fine 3D modeling is realized.According to the comparison of experimental results,the metro engineering measurement implementation method proposed in this paper has a greater advantage in measurement accuracy compared with the traditional method.The experiment proves that the method proposed in this paper has higher practicability and effectiveness.
