三维激光扫描仪在变形监测中的研究与应用

An Applied Study on the Three-dimensional Laser Scanner Used in the Deformation Monitoring

随着测量技术的快速发展,三维激光扫描技术在测量方面的应用日益流行.以某隧道项目为例,研究了三维激光扫描仪在变形监测中的应用.通过ScanStation2脉冲式三维激光扫描仪对该隧道进行点云数据采集,采用Geomagic软件进行3D分析,得到的变形监测结果与传统变形监测结果基本一致.同时,将两种方法结合使用,可以从微观、宏观两方面对隧道变形进行全面分析,效果良好.

In recent years,with the rapid development of the measurement technology,the three-dimensional laser scanning technology is more and more popular. Taking one tunnel project for example, the three-dimensional laser scanner used in the deformation monitoring is studied here. First, the cloud data of the tunnel is collected by ScanStation2 pulse three-dimensional laser scanner. Secondly,the 3D analysis is made using the Geomagic software. Thirdly,after being compared with the traditional results,our monitoring results are almost the same. With the new and the traditional leveling monitoring methods,the tunnel can be monitored both on macro and micro levels and with good results.
