水工程体无人机贴近摄影和质量控制方法摘要：针对倾斜摄影方法和近景摄影测量方法在水工程体三维实景重建中均存在不足的情况，提出了一种水工程体无人机贴近摄影和质量控制方法。通过带有RTK的无人机进行四点定位，从而快速确定拍摄面并进行贴近摄影；再对拍摄影像空中三角测量后的初始点云进行智能化分析，自动确定影像覆盖不足区域并进行补充摄影，以保证水工程体建模效果的精细与完整。通过清江水布垭大坝的无人机摄影与数据处理实验证明，该方法可高效快速地实现水工程的完整精细实景三维建模。关键词：无人机；摄影航迹规划；四点定位；水工程体；质量控制中图分类号：P231文献标志码：B文章编号：1672-4623（2023）03-0010-05UAVNap-of-the-objectPhotogrammetryandQualityControlMethodofWaterEngineeringLEISuqi1,NIUZhuangqun2,XIKe2,WEILingyun3,YANGKaijun4,5,ZHANGXianhua6(1.Wan’anHydropowerPlantofJiangxiElectricPowerCo.,Ltd.,Wan’an343800,China;2.SchoolofRemoteSensingandInformationEngineering,WuhanUniversity,Wuhan430079,China;3.ChangjiangSpatialInformationTechnologyEngineeringCo.,Ltd.,Wuhan430010,China;4.TheFirstSurveyingandMappingInstituteofHunanProvince,Changsha410007,China;5.KeyLaboratoryofNaturalResourcesMonitoringandSupervisioninSouthernHillyRegion,MinistryofNaturalResources,Changsha410007,China;6.JiangxiInstituteofAppliedTechnology,Ganzhou341000,China)Abstract:Inviewoftheshortcomingsofbothobliquephotogrammetrymethodandclose-upphotogrammetrymethodintherealscene3Drecon-structionofwaterengineering,weproposedaUAVnap-of-the-objectphotogrammetryandqualitycontrolmethodofwaterengineering.ThroughtheUAVwithRTKforfour-pointpositioning,themethodcanquicklydeterminetheshootingsurfaceandimplementthenap-of-the-objectphoto-grammetry,thenintelligentlyanalyzestheinitialpointcloudafteraerialtriangulationoftheshootingimagestoautomaticallydeterminetheinsuf-ficientareaofimagecoverage,andimplementssupplementaryphotography,toensurethefineandcomplete3Dmodelingeffectofwaterengi-neering.TheUAVphotogrammetryanddataprocessingexperimentsofQingjiangRiverShuibuyaDamprovethatthismethodcanachievethecompletefinerealscene3Dmodelingofwaterengin...
