| 摘 要： | 传统的断面测量方式工作效率较低,外业测量人员工作强度大,其测量的密度精度不高,速度很慢,对于一些要求高密度、危险无法到达的地段就无法测量。三维激光扫描技术的特点是扫描速度快、分辨率高、非接触式测量,利用三维激光扫描技术可以快速地获取被扫描物体表面的纹理和色彩,在市政道路工程断面测量中应用三维激光扫描技术,不仅能提高外业作业效率,减少外业测量人员的工作强度、避免危险情况发生,也能提升工程项目的内涵。本文利用LEICA P40三维激光扫描仪扫描道路获取道路点云,研究利用道路点云数据绘制道路纵横断面的作业流程、方法。

| Abstract: | The traditional cross-sectional measurement method is inefficient,and the work intensity of the field surveyors is large.The density accuracy of the measurement is not very high,and the speed is slow.It is impossible to get the high-density point clouds data and the data of dangerous areas.The 3D laser scanning technology with fast scanning speed,high resolution,non-contact measurement,can quickly record of the measured complex texture surface,The 3D laser scanning technology will be smoothly done and easily solved these difficulties.In this paper,we get point clouds data by using the laser 3D scanning technology,and discuss the process and method of plotting cross section using point clouds data. |
