三维激光扫描技术在隧道横纵断面测量中的应用研究

Application Research of Three-Dimensional Laser Technology in the Transect and Vertical Section Surveying of Tunnels

为解决传统测量手段在隧道测量中遇到的空间小,变化大,断面获取不灵活等问题,现采用三维激光扫描测量技术实现隧道横纵断面图的绘制.数据成果主要包括隧道横纵断面图及隧道走向图.研究结果表明,该方法由于其完整的隧道点云模型,可以准确地绘制横纵断面图,并且根据实际需要,可以灵活绘制横断面图.

Traditional methods may meet the problems such as small space,large changes of elevation and less flexibly in plotting the transect in vertical section survey.In order to solve these problems,according the real condition of the tunnels,the three-dimensional laser scanning technology to acquire the transect and vertical section is used in the paper.The data results include the transect and vertical section as well as the tunnel trend chart.The research results show that the transect and vertical section can be plotted flexibly and correctly based on integrated tunnel point-clouds model.
