无人机遥感系统在风暴潮灾害损失评估中的应用初探

Preliminary Application of UAV Remote Sensing System in Storm Surge Disaster Loss Assessment

无人机遥感系统由于具有响应迅速、起降方便、可低空作业、分辨率高等优点,在自然灾害调查及应急救援中有广泛的应用。文章在台风"苏力"登陆后,利用无人机遥感系统及时获取台风登陆点附近25km^2范围的高分辨遥感影像,通过对遥感影像进行分析处理,提取研究区域典型风暴潮承灾体的灾害损失信息并对其进行统计分析,为风暴潮灾害损失评估提供数据支持;对无人机低空遥感系统在风暴潮灾害调查及灾害损失评估中的应用作初步探索。结果表明,无人机低空遥感系统在风暴潮灾害调查中的应用具有一定的可行性且取得一定成果,但受制约的方面也较多,今后还需结合风暴潮灾害特点作进一步的应用探索。

UAV remote sensing system has the advantages of rapid response,easy takeoff and landing,low operation,high resolution,and has been widely used in natural disaster investigation and emergency rescue.After the typhoon ＂Su Li＂landed,UAV remote sensing system was used to obtain high resolution remote sensing images in the range of 25km^2 near the typhoon landing point in time.The disaster loss information of typical storm surge disaster bearing body in the study area was extracted and analyzed statistically,which provided data support for storm surge disaster assessment,through the analysis and processing of remote sensing images.The preliminary application of low altitude UAV remote sensing system in storm surge disaster investigation and disaster loss assessment was explored.The results showed that the application of low altitudeUAV remote sensing system in the storm surge disaster investigation has certain feasibility and could achieve certain results,while with a lot of constraints.Further application and exploration are needed to be performed combining with the characteristics of storm surge disaster.
