无人机摄影测量在黄河宁夏河道工程中的应用

Application of low altitude UAV photogrammetry technology in the Yellow River Ningxia river project

以黄河宁夏河道工程地形图测绘为例,探讨了利用无人机低空摄影技术制作正射影像和地形图的作业流程和技术方法,论证了其可行性,并分析了无人机低空摄影测量的特点,以供参考。

Taking the the Yellow River Ningxia river engineering topographic mapping as an example,discusses the use of non operation process and technical method of making topographic altitude of photography,and its feasibility is analyzed,the characteristics of low altitude UAV photogrammetry,so as to reference.
