基于大重叠度影像无人机航测地形图技术方法研究

Research of UAV Aero-photogrammetry Technology based on high overlap images

为解决无人机航测大比例尺地形图精度问题,采用大重叠度影像无人机航测的技术方法,完成了陕西省A测区约50 km2,1:1 000地形图航测项目,统计分析了该项目的空中三角测量精度,检测了立体测图数据的平面和高程精度,文中论述了该技术方法的适宜性及其不足之处。

To solve the precision problem of large scale topographic map based on UAV aero- photogrammetry, thepaper completes the aero - photogrammetry of 50 km2 , 1 ： 1 000 topographic map in a test zone A in shangxi with thetechnique of the high overlap image. Also the precision of the aerial triangulation is analyzed. And the plane andvertical precision of the stereo mapping data is detected. What＇ s more, the paper discusses the suitability of thetechnology method and its shortcomings.
