| 摘 要： | 目前,对于城市1∶500数字化地形图数据的获取与更新中,全野外数字测图仍是主要的测绘方式。如何利用新的测量手段提高生产效率和降低劳动强度,是值得关注的问题。文中阐述无人机和地面三维激光扫描仪新技术在城市基本地形图测绘中的应用,利用无人机航测生产的1∶500正射影像图成果,辅助进行全野外测图;利用地面三维激光扫描仪,将快速获取的三维点云数据加以处理,用于测绘成果质量检查。通过这些新技术,对提高1∶500城市基本地形图的生产效率进行有益的尝试,对同类工程具有借鉴意义。

| Abstract: | At present,for the city 1:500 digital topographic map data acquisition and update,the whole field digital mapping is still the main method.How to use new technique to improve production efficiency and reduce labor intensity is a matter of concern.This paper states the exploration and application of new technology in surveying and mapping of basic topographic maps of cities,including the making use of 1:500 digital orthophoto map produced by unmanned aerial survey which assists in the whole field mapping, and the making use of three dimensional point cloud produced by terrestrial laser scanner which checks the quality of surveying and mapping results.Through these new technologies,it is helpful to build the new model of the basic topographic mapping of the city. |
