基于无人机遥感技术的矿山地质精细化测绘方法高霞飞（湖北省地质局第四地质大队，湖北咸宁437100）摘要：为提高地质测绘图像的清晰度，引进无人机遥感技术，设计矿山地质精细化测绘方法。根据无人机遥感测绘作业的需求，参照采用航空网络和地区网络的布局方式，利用航线网络，在各高程航线间设置适当数量的像控点；使用CGO技术，处理测绘中的网络平差数据，采集无人机遥感测绘信息；计算镜头误差的方式，建立一元线性回归方程，补偿并处理测绘数据；自动连接多个提取点，执行自动操作，转化成果文件；利用地质空间复合体模板，录入点、线、面等参照性数据，生成矿山地质测绘结果三维模型，实现对矿山地质的精细化测绘。以某地区大型矿山工程为例，设计对比实验，实验结果证明：设计的地质测绘方法，在矿山地质测绘时的实用性更强，可以确保测绘图像的清晰度在80%以上。关键词：无人机；测绘方法；精细化；地质；遥感技术；矿山中图分类号：P623.1文献标志码：A文章编号：1009-0797（2023）02-0010-04FinemappingmethodofminegeologybasedonUAVRemoteSensingTechnologyGAOXiafei（FourthGeologicalteamofHubeiGeologicalBureau,Xianning437100,China）Abstract:Inordertoimprovetheclarityofgeologicalmappingimages,theUAVremotesensingtechnologyisintroducedandtheminegeologicalfinemappingmethodisdesigned.AccordingtotherequirementsofUAVRemoteSensingSurveyingandmappingoperation,withreferencetothelayoutofaviationnetworkandregionalnetwork,anappropriatenumberofimagecontrolpointsaresetbetweenthealtituderoutesbyusingtheroutenetwork;UseCGOtechnologytoprocessnetworkadjustmentdatainsurveyingandmappingandcollectremotesensingsurveyingandmappinginformationofUAV;Themethodofcalculatingthelenserror,establishingalinearregressionequation,compensatingandprocessingthesurveyingandmappingdata;Automaticallyconnectmultipleextractionpoints,performautomaticoperations,andconverttheresultfiles;Byusingthegeologicalspacecomplextemplate,thereferencedatasuchaspoints,linesandplanesareinput,andthethree-dimensionalmodelofminegeologicalmappingresultsisgeneratedtorealizethefinemappingofminegeology.Takingalarge-scalemineprojectinacertainareaasanexample,acomparativeexperimentisdesigned.Theexperime...
