摘要
针对常规的地铁隧道限界测量方法检测效率低下、易漏测的情况,该文采用基于三维激光扫描技术的限界检测方法进行检测。实验证明,该方法能够在短时间内获得大量的点云数据,极大地提高了外业效率;使用点云数据可以进行局部限界分析和整体限界分析,保证了限界分析的全面性;与全站仪法进行对比分析,三维激光扫描技术限界检测法测量的结果准确可靠。
In view of the low detection efficiency and easy missing detection of the conventional subway tunnel boundary measurement method,this paper uses the boundary measurement method based on 3D laser scanning technology to detect.The experiments show that this method can obtain a large number of point cloud data in a short time and greatly improve the field efficiency;Using the point cloud data,the local boundary analysis and overall boundary analysis can be carried out,it ensures the comprehensiveness of boundary analysis;Compared with the total station method,the boundary measurement result of 3D laser scanning method is accurate and reliable.
