基于丘陵地形无人机测绘大比例尺地形图精度分析

Precision Analysis of Mapping Large Scale Topographic map by UAV Based on Hilly Terrain

本文利用无人机对丘陵地形中的项目区域进行航拍,通过野外像控点布设、空三加密、三维立体建模等流程生产1∶1000大比例尺地形图,并在地形图上选取若干地物点实地采集三维坐标进行精度验证,以此证明在丘陵地区利用无人机进行大比例尺地形图测绘的可行性、高效性。

In this paper, drones are used to take aerial photography of the project area in the hilly terrain. Through the process of field image control point layout, aerial three-dimensional encryption, and three-dimensional modeling, a 1∶ 1000 large-scale topographic map is produced, and several sites are selected on the topographic map. The three-dimensional coordinates of the object points are collected on the spot for accuracy verification, which proves the feasibility and efficiency of large-scale topographic map surveying and mapping using drones in hilly areas.
