无人机航测技术在数字测图的应用

The Application of UAV Surveying Technology in Digital Mapping

摘要: 文章使用DJI Phantom 4 RTK无人机进行航空摄影数据采集，利用Context Capture软件创建三维模型，使用DP-Modeler软件对三维模型进行纹理修复，3D模型方便DSM和OSGB的生产，CASS软件生产数字线划图。地形图可用于攀枝花学院本部校区下一步规划建设中，并且对此次实验进行精度分析，对生产实践有一定的指导意义。

Abstract: This paper uses the DJI Phantom 4 RTK drone to collect aerial photography data, creates a 3D model using context software, and performs texture repair on the 3D model using DP-Modeler software. The 3D model facilitates the production of DSM and OSGB, and CASS software is used to produce digital line maps. The topographic map can be used in the next planning and construction of the Panzhihua University main campus, and the accuracy analysis of this experiment is conducted, which has a certain guiding significance for production practice.
