【摘要】 无人机系统具有机动灵活、快速响应的优点,很适合自然灾害灾情监测和评估工作。首先介绍了无人机遥感系统的组成,以及在云南盈江地震灾害中的应急过程和数据处理流程。然后,利用获取的无人机遥感影像,对比灾前的高分辨率卫星影像,对盈江县城的房屋损毁、救灾帐篷和道路损毁及交通拥堵情况进行了监测评估,取得了较好效果。但无人机遥感系统还需要在数据处理效率、三维信息获取方面做进一步改善。更多还原

【Abstract】 Unmanned aerial vehicle(UAV) system has the advantage of flexible,rapid response.It is suitable for natural disaster monitoring and assessment.This paper introduced the composition of UAV remote sensing system,the emergency process and data process flow in Yingjiang,Yunnan earthquake disaster.Then,the UAV remote sensing image and pre-disaster high resolution satellite image were compared,housing damage,disaster relief tents,roads damage and traffic jam were monitored and assessed.It turned out that results are good.However,the data processing efficiency and the acquisition capability of three dimension information for UAV remote sensing system need to be further improved.更多还原
