无人机航测技术在丘陵地区大比例尺测图的应用研究

Application of UAV Aerial Survey Technology in Large-scale Mapping in Hilly Area

随着省市县镇村国土空间规划的全面铺展,大比例尺地形图对时效性的要求越来越高,如何快速获取高精度大比例尺地形图成为一个难题。本文以丘陵地区为研究区域,采用无人机倾斜摄影测量和立体测图技术结合的方法,完成地形地貌复杂的大比例尺地形图测绘项目。

With the development of five level land space planning of provinces,cities,counties,towns and villages in China,the planning and design of key areas require high-precision large-scale topographic map.How to quickly and accurately obtain large-scale topographic map has become a difficult problem.In this paper,the complex topography of hilly areas as the research area,comprehensive oblique photogrammetry and traditional UAV mapping advantages and disadvantages,it solves the difficult problems such as the contour line drawing of the terrain in the hilly area,the high precision of houses and the connection of electric poles.Finally,the combination of UAV′s oblique photogrammetry and traditional photogrammetry technology forms a set of UAV aerial survey technology scheme to obtain large-scale topographic map quickly and accurately.
