摘　　要：在地形起伏大的山区进行常规航空摄影测量,航空摄影要根据地形高差进行摄影分区,即便如此分区,仍会出现局部与分区基准面高差超限、地面分辨率相差较大、飞行质量和影像质量难以控制,同时影响飞行效率的问题。为控制地形起伏大的地区影像地面分辨率的差异对成果的影响,避免繁琐的航摄分区,提高飞行效率,本文首先论述了地面分辨率对测量成果的影响,然后提出了在地形高差大的山区,采用无人机飞行航迹与对应地形剖面线相似进行仿地飞行、不用航摄分区的方法。采用该方法应用于宿松县铜铃寨金多金属矿1∶1 000航空摄影地形测量项目中,成果经检验质量良好,工作效率高,该方法可靠、可行、可用。Conventional aerial photogrammetry should be zoned by mitigating differences in terrain elevations in sharp-relief mountainous areas.Even so,difference between local flight height and datum level of a specific zone will still exceed the set limit,difference in ground resolution is large,flight and image qualities are difficult to control,and flight efficiency is reduced.In order to control the effect of the difference in ground resolution on the measurement results in sharp-relief areas,avoid tedious zoning for aerial photography and improve flight efficiency,this paper firstly discusses the influence of the ground resolution on the measurement results,and then puts forward the method of UAV’s flight following the outline of landform without aerial photographic zoning in sharp-relief terrains.This method has been applied to the 1∶1000 topographic surveying project of the Tonglingzhai gold polymetallic ore deposit in Susong County,and proved good in the quality of work results,high in work efficiency,and workable and reliable itself.
