摘要
无人机航测技术可应用于陆地地形图的高效测绘,无人船单波束系统使水下地形图测绘变得更为便捷。针对水陆结合区域地形图测绘的难点,本文论述了将两者的优势进行互补的协同作业方法,可以更加快速高效地获取高精度的正射影像和三维模型,以及水陆一体化点云成果。在广西壮族自治区桂平市农(渔)光互补光伏发电项目中,应用该协同作业方法开展地形图测绘工作,与传统测绘方法相比,极大地缩短了外业测绘的时间。经过数据检查,无人机测得的陆地成果精度和无人船测得的水下成果精度均符合规范要求,证明该作业方法具有重要的应用价值。
Aerial surveys by unmanned aerial vehicles(UAVs)can be applied to efficient onshore topographic map surveying and mapping.The single-beam system of unmanned ships can make underwater topographic map surveying and mapping more convenient.In response to the difficulties of topographic map surveying and mapping in areas where water and land coexist,this paper explored a collaborative operation method that combined the advantages of the two.This method could more quickly and efficiently obtain high-precision orthoimages and three-dimensional(3D)models,as well as point cloud data of land and water integration.The collaborative operation method was applied to carry out topographic map surveying and mapping in the complementary photovoltaic power generation project of fishing and lighting in Guiping City,Guangxi Zhuang Autonomous Region.Compared with traditional surveying and mapping methods,it greatly shortened the time for field surveying and mapping.After data inspection,the accuracy of land results obtained by UAVs and underwater results obtained by unmanned ships were in line with specifications,which proved that the method has significant engineering significance.
