摘　　要：针对高速公路改扩建勘测的特点与精度要求,本文研究车载LiDAR测量技术在高速公路改扩建勘测中的应用。首先利用车载LiDAR系统沿高速公路往返测量获取路面点云数据,然后用采集的高速路两侧立柱平面位置和水准测量的路面高程点分别对点云平面坐标和高程进行改正、拟合,使点云精度和密度满足高速路改扩建勘测设计需求。该技术在京藏高速银川段改扩建工程中得到了应用,成果精度完全满足要求。In view of the characteristics and precision of the highway reconstruction and extension surveying,this paper puts forward the Mobile LiDAR measurement technology.In order to meet the point cloud precision and density requirements of the expressway reconstruction and extension,first of all,the Mobile LiDAR system surveyed to and fro along the highway to obtain the surface point cloud data,then the plane coordinates of point cloud is corrected by the stand column and the elevation is fitted by the levelling control points on both sides of the hard shoulder of highway.The technology has been applied in the reconstruction and extension project of Yinchuan section of Beijing Tibet Highway,and the results meet the requirements completely.
