摘　　要：水利工程项目常受限于水域与多变的气候条件,测量环境复杂多变。为满足规划、设计、运营管理的需求,此类项目需频繁进行大比例尺地形图测绘。文章以襄河口闸为例,探讨了免像控无人机摄影测量技术的应用。该技术能够快速获取水利工程项目地形图,其精度满足1∶500大比例尺测图的平面精度要求,极大地提升了水利工程项目的测量工作效率。Water conservancy projects are often constrained by water areas and variable climatic conditions,resulting in a complex and ever-changing measurement environment.To meet the needs of planning,design,and operational management,such projects require frequent surveying and mapping of large-scale topographic maps.Taking the Xianghe Estuary Gate as an example,this paper explores the application of Unmanned Aerial Vehicle(UAV)photogrammetric technology without image control points.This technology can quickly obtain topographic maps of water conservancy projects,and its accuracy meets the plane accuracy requirements of 1∶500 large-scale mapping,significantly enhancing the measurement efficiency of water conservancy projects.
