摘要
针对某地铁线路工程隧道测量真实情况不完整、数据采集效率较低等问题,对三维激光扫描技术在隧道测量中的应用进行了研究.研究结果显示:不同三维激光扫描测量设备具有大致相同的测量精度,且三维激光扫描技术作业效率高;投入人员较少,虽然会产生微小误差,但是该误差多由测量方式和测量环境所引起,在实际测量时加以控制可以进一步提高测量精度.由此说明:三维激光扫描技术可以应用于竣工验收阶段的测量工作,能提高检测精度并减少测量验收人员的工作量.
Abstract
Aiming at such problems as incomplete tunnel condition and low data acquisition efficiency in a certain subway line project,the application of 3D laser scanning technology was studied in the tunnel surveying.The research results show that:different measuring equipment of 3D laser scanning has roughly the same measurement accuracy,and 3D laser scanning technology is of high operation efficiency and with insufficient personnel input.Although it will have small errors which are mostly caused by the measurement method and the measurement environment,the measurement accuracy can be further improved by controlling them in the actual measurement.Therefor it shows that the 3D laser scanning technology can undertake the measurement work in the completion and acceptance stage,improve the detecting accuracy and reduce the workload of the measurement and acceptance personnel.
