微型无人机遥感系统在汶川地震中的应用

Application of miniature unmanned aerial vehicle remote sensing system to Wenchuan earthquake

微型无人机遥感系统具有运行成本低、执行任务灵活性高等优点,是遥感数据获取的重要工具之一。首先介绍了微型无人机遥感系统的组成,并设计了微型无人机遥感监测的技术流程,最后应用微型无人机遥感系统对"5.12汶川大地震"的重灾区北川县城进行了航拍,获得了107张高清晰的航空照片。通过图像拼接和几何校正,对比震前的卫星影像,对灾区的受灾情况进行了初步评价,取得了较好的效果。

Miniature unmanned aerial vehicle remote sensing system（MUAVRSS） plays an important role in remote sensing data acquisition.It has many advantages,such as low operation cost,good running flexibility,and so on.First,this article introduces the system composition of MUAVRSS.Then it designs a technical process of monitoring serious natural disaster using MUAVRSS.Finally,we utilized MUAVRSS for taking photos of the town of Beichuan County,which is a heavy disaster area of Wenchuan earthquake.Hundred and seven clear aerial photos were acquired.According to image mosaic and geometry correction,we preliminarily evaluated the suffering condition by comparing to the spaceborne images before the strong earthquake.Better efforts were realized.
