基于移动三维激光扫描的隧道结构 监测方案研究与应用

Application and research of tunnel structure monitoringsolution based on moving 3D laser scanning system

地铁运营监测存在诸多困难,文中利用移动式三维扫描以推行扫描方式获取狭长隧道结构点云数据,逐环提取环片结构变化信息实现隧道结构变化监测;构建数据管理平台对各项监测成果进行管理和分析,实现隧道变化精准监测。该方案具有强大的效率优势,促进了地铁运营监测行业的发展。

There were many difficulties in subway operation monitoring,in this paper,the moving 3D scanning was used to obtain the point cloud data of narrow and long tunnel structures by implement scanning,and the ring structure change information was extracted ring by ring to realize the tunnel structure change monitoring.Data management platform was built to manage and analyze the various monitoring results to achieve the accurate monitoring of the tunnel changes.This solution promoted the development of the subway operation and monitoring industry with the strong efficiency advantages.
