背包式三维激光扫描仪在村庄地籍调查工作底图测量中的应用

Application of Backpack 3D Laser Scanner in Surveying and Mapping of Cadastral Survey Base Map in Villages

村庄地籍调查工作底图测量面临环境复杂、信号不佳等问题,传统GPS+全站仪和测距仪的方法不能满足目前地籍测量的需求。深入研究了徕卡背包式三维激光扫描仪的原理和应用。利用徕卡背包式三维激光扫描仪在实验区域进行外业扫描,基于获取的点云开发三维成图软件,最终绘制村庄地籍调查工作底图。对背包点云和传统测量技术进行了平面位置和相对长度的对比分析。结果表明,徕卡背包式三维激光扫描仪能满足村庄地籍调查工作底图测量的要求,提高了测量效率,解决了隐蔽点测量难题,为村庄地籍调查工作底图测量提供了一种新的技术手段。

The traditional GPS+total station and rangefinder can’t meet the needs of cadastral survey due to the complex environment and poor signal.In this paper,we studied the principle and application of Leica backpack 3D laser scanner in detail.We used Leica backpack 3D laser scanner for field scanning in the experimental area,developed 3D mapping software based on point cloud,and drew the working base map of village cadastral survey.We compared the plane position and relative length of backpack point cloud with traditional survey technique.The results show that Leica backpack 3D laser scanner can meet the requirements of village cadastral survey base map,improve the village cadastral survey efficiency,solve the concealment point measurement problem,and provide a new technical means for the base map survey of village cadastral survey.
