)基于无人机的城市局部区域三维测绘建模摘 要本文主要讨论了无人机在城市局部区域内三维测绘建模中的应用，从无人机的操作，传感器的选择，测绘系统，数据的处理与传输这几个方面详细介绍了无人机在区域三维测绘建模中所扮演的主要角色。由于航测的小型无人机以机动性高，灵活性强，飞行速度快，经济要求低等一系列的优点使得无人机在城市局部区域三维测绘建模或重点区域和小型小范围区域的航测上一步一步取缔了传统的人工地图测绘。无人机这种得天独厚的优势，使得无人机航测所带来的经济效益巨大并且使用无人机可以更加快速的获得高质量以及高分辨率的遥感影像。在无人机摄影方法的选择上，本文就传统的垂直航空摄影与倾斜摄影进行对比，分别使用航测无人机分别使用这两种方法来采集数据，最后绘制成图进行对比。最终得出相对于传统的垂直航空摄像，倾斜摄像能够比较真实的反映目标地物的周边情况，并且斜摄像的数据量小等优点。本文中对于无人机和无人机航空摄影方法以及无人机在城市局部区域三维测会中的应用都是以现有的技术下进行讨论研究，为以后探讨新的摄影方式做铺垫也为无人机在航测中的应用进行研究。关键词：无人机 航测 倾斜摄像 三维建模 I)××× UAV system design and productionABSTRACTThis paper mainly discusses the application of small four-axis UAV in 3D surveying and mapping modeling of local urban areas.
