摘要
本文针对道路工程测量的难点问题,采用SZT-R1000车载激光雷达测量系统,进行道路数据采集.对该方法应用于道路工程测量中的关键问题进行了探讨,同时提出了基于距离将误差值反向加权平差的方法对点云数据进行精度优化.经对比分析:该方案不仅数据采集效率高,而且数据精度可靠.经精度优化后的点云数据平面精度可以达到5cm以内,高程精度可以达到3cm以内,在道路工程项目中有广阔的应用前景.
Abstract
The paper utilizes the SZT-R1000 vehicle LiDAR measurement system to collect road data according to challenging issues in road engineering measurement.It discusses the key problems associated with this method in road engineering survey and proposes a distance-based reverse weighted adjustment approach to have the accuracy of point cloud data optimized.Through comparative analysis,it is demonstrated that this scheme not only achieves high efficiency in data acquisition but also ensures reliable data accuracy.After precision optimization,the planar accuracy of point cloud data can be improved up to less than 5 cm,while the elevation accuracy can reach 3 cm or less.Consequently,it exhibits promising prospects for application in road engineering projects.
