无人机遥感系统应用与影像有效利用的探讨

Discussion of Deeper Use of the Digital Images which are Gathered by the UAV Remote Sensing System

无人机遥感系统是快速获取数字影像的重要途径之一。本文结合无人机遥感系统在自然地质灾害中的应用,探讨了专门为灾害应急服务的无人机数字影像如何有效利用的问题。文章首先介绍了无人机遥感系统的结构,及在洱源县泥石流灾害应急中的应用,包括影像数据获取和灾情评估。最后,通过分析多次灾害应急航摄影像的共同特点,探讨充分利用影像数据问题,通过加入影像坐标数据,对灾害进行定量分析;提高无人机航摄地面高程精度,使其成为制作4D测绘产品及大比例尺地形图的新数据源。

UAV （Unmanned Aerial Vehicle, UAV） remote sensing system is an important way to get the digital images. The article is about the deeper use of the digital images which are gathered by the UAV in the geological disasters. The article introduces about the structure of the UAV remote sensing system firstly. An example which is about Eryuan County ＂8.06＂ large torrential debris flows is given to introduce the apply of the UAV. Gathering the digital images of the disaster areas and disaster assessment are also introduced in this article. Finally,we get a way to do deeper use of the digital images which can be used to make 4D maps and so on.
