摘　　要：三维激光扫描技术作为目前测绘领域的新技术之一,具有非接触测量、采集速度快、数据精度高等特点。它是继GPS后的又一项测量技术革新。本文以三维激光扫描仪在道路工程中的应用分析为例,选取甘肃省兰州市某一新建环城路为分析对象,对其进行实地三维扫描,详细地介绍了点云数据拼接、坐标转换以及利用三维激光扫描数据生成道路图的整个过程,并进行两种数据的精度分析,对比得到其测量精度。Three-dimensional laser scanning technology is one of the new technologies which has the advantage of noncontact measurement,acquisition of high speed,accurate dates.It is yet another measure technological innovations after GPS.In this paper,it introduces the three-dimensional laser scanner application in Road project,choose a road of LanZhou as an object.It describes the splice point cloud data,coordinate transformation to the resulting road map of the whole process,analyses and compare the accuracy of the two kinds of data,then get the final measurement accuracy.
