无人机低空倾斜摄影测量技术在大比例尺测图中的应用

The Application of UAV Low-Altitude Oblique Photogrammetry Technology in Large Scale Mapping

本文使用DJI Phantom 4 RTK无人机进行倾斜摄影数据采集,利用Context capture软件创建三维模型,并使用DP-modeler软件对模型进行纹理修复,且依靠清华山维EPS对三维模型进行1:500大比例尺地形图制作,地形图可应用于太阳湖公园的下步规划建设中,并进行了精度分析,对实践生产具有一定指导意义。

In this paper, DJI Phantom 4 RTK UAV was used for oblique photography data acquisition, Context capture software was used to create a three-dimensional model, and DP-modeler software was used to repair the geometric accuracy and texture of the model, and the three-dimensional model was carried out with Tsinghua Shanwei EPS. 1:500 large scale topographic map can be used in the next planning and construction of Sun Lake Park, which has certain guiding significance for practical production.
