摘要
目前道路断面测量多采用传统的RTK、全站仪或者架站式扫描仪进行测量,存在数据采集效率低,覆盖面窄的情况。本文介绍一种利用机载激光雷达进行道路断面测量的方法,可实现高效率采集及内业成图。该方法主要涉及三个关键技术问题,即点云如何精确分类、断面点云截取参数如何确定和断面点云高精度拟合。本文针对这三个关键技术问题的解决思路进行详细的阐述。最后利用该方法与传统RTK测量方法进行对比,验证该方法的精度可靠性。
Traditional road cross-section measurement methods,including RTK(Real-Time Kinematic),total stations,or stationary scanners,are confronted with defects such as low data collection efficiency and limited coverage.This study presents an aerial LiDAR(Airborne Light Detection and Ranging)method for achieving high-efficiency data gathering and post-processing mapping in road cross-section measurement.On this basis,it thoroughly explains the proposed method's solution to the three main technological issues,including accurate point cloud categorization,determination of cross-section point cloud extraction parameters,and high-precision fitting of cross-section point clouds.Finally,the proposed method is compared with the traditional RTK measurement method to verify its accuracy and reliability.
