摘要
传统河道测量方法存在效率低、测量密度不足以及不适应复杂地形等问题,难以满足现代水利工程对高精度、高时效地形数据的需求。文章提出了一种基于无人机(UAV)航测的河道测量技术体系,并以湖南省蒸水中游为实证对象,构建了涵盖平台配置、航线规划、控制点布设、数据处理及断面分析的完整流程,并与实时运动测量技术(RTK)对比,验证无人机航测在精度可控前提下的高效率和高覆盖优势。差值分析结果揭示了河道主槽的迁移与堆积冲刷特征,表明该技术具备较强的水文地貌演变监测能力。
Traditional river measurement methods suffer from low efficiency,insufficient measurement density,and unsuitability to complex terrain,making it difficult to meet the demands of modern hydraulic engineering for high-precision and timely terrain data.In response to this issue,the article proposes a river measurement technology system based on unmanned aerial vehicles(UAV)aerial survey,and takes the middle reaches of the steamed water in Hunan Province as the empirical object to construct a complete process covering platform configuration,route planning,control point layout,data processing,and section analysis.And compared with real-time kinematic measurement technology(RTK),verify the high efficiency and high coverage advantages of unmanned aerial vehicle aerial surveying under the premise of controllable accuracy.The difference analysis results reveal the migration and accumulation erosion characteristics of the main channel of the river,indicating that this technology has strong monitoring capabilities for hydrological and geomorphological evolution.
