应用三维激光扫描技术的某道路大修工程测量研究

Research on a Road Overhaul Engineering Survey by Using 3D Laser Scanning Technology

该文从市政道路大修工程对测绘的需求出发,探讨了三维激光扫描技术在市政道路工程测量中的外业作业方法与内业成图方法。结果表明,与传统地形测量手段相比,三维激光扫描技术可以快速获取海量点云数据,极大地提高了外业测量工作效率,降低外业测量工作的强度,将工作重点转移到内业。另外,该文通过将扫描仪测图与全站仪测图成果进行对比分析,发现三维激光扫描仪的精度完全可以满足地形图测绘的要求。

Staring from the requirements of surveying and mapping in municipal road overhaul engineering,this paper discusses the field operation method and internal mapping method of 3D laser scanning technology in municipal road engineering surveying.Results show that compared with traditional topographic survey methods,3D laser scanning technology can quickly obtain massive point cloud data,which greatly improves the work efficiency of field survey,reduces the intensity of field survey work,and shifts the focus of work to the internal work.In addition,through the comparative analysis of the mapping results of the scanner and those of the total station,it is found that the accuracy of 3D laser scanner can fully meet the requirements of topographic mapping.
