摘　　要：大型河道类地形测绘项目测区呈长条带状且带宽狭窄,如果参照国家规范面状区域像控点布设方式,存在像控点数量多且野外布设不便利等缺点,针对该问题,文章研究了四种像控点布设方案并进行空中三角测量精度对比试验,得出一种适合带状测区无人机(UAV)测图控制点布设方案,在保证相应比例尺地形图精度要求的前提下,有效减少内外业像控测量的工作量。The survey area of large river topographic mapping project is long strip and narrow bandwidth.Referring to the national standard layout method of image control points in planar area,there are many shortcomings,such as the number of image control points is large and the field layout is inconvenient.In view of this problem,four image control point layout schemes were studied and the aerial triangulation accuracy comparison test was carried out to obtain a scheme suitable for the layout of unmanned aerial vehicle(UAV)mapping control points in the strip survey area.On the premise of ensuring the accuracy requirements of the corresponding scale topographic map,the workload of indoor and outdoor image control measurement could be effectively reduced.
