摘要
针对目前复杂山区测图精度难以满足1∶500地形图规范要求的情况,本文通过分析飞马D2000多旋翼无人机的倾斜摄影测量作业流程及大比例尺航测的关键技术,结合实际测图实验,对三维模型数据与实地测量数据进行精度对比分析,结果表明,倾斜摄影测量技术能够满足山区1∶500地形图的精度要求,有效地提高了工作效率,可为山区内的大比例尺测图项目建设提供参考。
At present,the mapping accuracy of complex mountainous areas is difficult to meet 1∶500 scale topographic map specification requirements.In this paper,by analyzing the Feima D2000 multi-rotors Unmanned Aerial Vehicle(UAV)operation process and key technologies of large scale aerial photogrammetry,combined with the actual mapping experiment,the accuracy comparison analysis is carried out between 3D model data and field measurement data.The results show that oblique photogrammetry technology can meet the accuracy requirement of 1∶500 scale topographic map,which effectively improves the work efficiency and provides reference for the construction of large scale mapping projects in mountainous areas.
