摘　　要：传统的道路测绘方式,主要使用GNSS、全站仪与水准仪来完成,数据格式只能是单个点的坐标或高程,存在一定的概括误差。为了提高道路测绘的数据完整性、流程简单性、作业安全性,笔者测试了地面静态三维激光技术的实践和应用。本文重点介绍天宝Realworks点云处理软件、TBC高级版软件结合SLAM移动扫描仪在道路测绘中的应用,对其外业测量工作流程方法与精度控制手段进行探讨。并通过处理和分析点云,对道路进行三维测量、DEM建模、等高线绘制、纵横断面生成等测绘生产。后期对数据成果的精度进行检核。结果表明,天宝Realworks点云处理软件结合SLAM移动扫描仪以及TBC数据处理软件,能够满足公路测设中的外业数据采集、内业数据处理以及外业道路放样的需要,值得在公路测设中推广和应用。The traditional way of road surveying and mapping mainly uses GNSS, total station and level. The data format can only be a single point of coordinate or elevation, and there is a certain general error. In order to improve the data integrity, process simplicity and operational safety of road mapping, we tested the practice and application of ground static 3D laser technology. This paper mainly introduces the application of Trimble Realworks point cloud processing software, TBC advanced version software combined with SLAM mobile scanner in road surveying and mapping, and probes into its external measurement workflow nlethod and precision control means. Through processing and analyzing the point cloud, the road survey, DEM modeling, contour drawing, vertical and horizontal section generation and other surveying and mapping production are carried out. In the later period, the accuracy of the data results is checked. The results show that Trimble Realworks point cloud processing software, combined with SLAM mobile scanner and TBC data processing software, can meet the needs of external data collection, internal data processing and external road layout in highway surveying and setting. It is worth popularizing and applying in highway survey.
