摘　　要：以某水库为例,探究了低空无人机遥感技术在水利工程测绘中的应用。选用KC1600固定翼无人机搭载SONY A7R高分辨率数码相机进行航测,规划5条航线。在设定航向和旁向重叠度、航高等参数后,开始进行低空测量;在校验相机文件后,进行影像快速拼接;布置像控点后,进行空中三角测量。根据测量结果,生成数字高程模型(Digital Elevation Model,DEM)格网,在DEM基础上,进行微分纠正和数字镶嵌,得到数字正射影像图(Digital Orthophoto Map,DOM),该图的平面中误差为0.355 m,满足《低空数字航空摄影测量内业规范》(CH/T 3003—2021)的精度要求。Taking a certain reservoir as an example,this paper explores the application of low altitude unmanned aerial vehicle(UAV)remote sensing technology in water conservancy engineering surveying and mapping.KC1600 fixed wing unmanned aerial vehicle equipped with SONY A7R high-resolution digital camera was selected for aerial surveying,and five flight routes were planned.Low altitude measurements were started after setting heading and lateral overlap,altitude and other parameters.After verifying the camera files,the images were quickly spliced;After arranging image control points,aerial triangulation was carried out.Based on the measurement results,Digital Elevation Model(DEM)grids were generated,and differential correction and digital tiling were performed on the DEM to obtain Digital Orthophoto Map(DOM)maps.The plane error of this map is 0.355 m,which meets the accuracy requirements of the"Code for Low altitude Digital Aerial Photogrammetry"(CH/T 3003—2021).
