| 摘 要： | 随着无人机技术的快速发展,无人机航空摄影测量的精度也大大改善,以无人机为平台低空摄影测量大比例尺地图成为可能。本文以旋翼无人机搭载非测量型相机,通过布设不同数量像控点进行分析和研究,得到无人机摄影测量在农村地区像控点布设规律。结果证明在合理像控点布设的情况下,无人机测图数字成果空中三角测量、平面和高程精度均可满足1∶500、1∶1000、1∶2000大比例尺地形测图的精度要求。

| Abstract: | With the rapid development of UAV technology,the accuracy of UAV aerial photogrammetry has been greatly improved.It is possible to use a UAV as a platform to measure large-scale maps at low altitude.In this paper,UAV is equipped with a non-measuring camera.The analysis and research are carried out by arranging different numbers of image control points to obtain the law of the control point of the UAV photogrammetry in rural areas.The results show that in the case of reasonable image control point layout,the aerial triangulation,plane and elevation accuracy of the digital results of the UAV can meet the accuracy requirements of 1∶500,1∶1000,1∶2000 large scale topographic maps. |
