无人驾驶飞机系统(Unmanned Aerial System),即无人机,是一种不需要飞行器驾驶员上机操控的,通过旋翼或固定翼产生拉力或升力,并在大气层内飞行的飞行器。若将遥感技术与无人机系统结合于一体,即构成无人机遥感系统(Unmanned Aerial Vehicle Remote Sensing System)。无人机遥感系统可搭载相机以及多光谱、热红外、激光雷达等多遥感传感器,以机动性能较好的无人机为载体,可以快速而有效率地获取照片、视频、以及光谱等各种所需数据资料。相比更为传统的航空、航天遥感系统,无人机遥感系统具有显著优势。无人机可以在低空飞行,在云层下成像,这很好的改善了传统航天遥感容易受到云层干扰的缺点;同时,无人机由于体积小,便携性高,具有随时监测,实时传输的能力,很好的弥补了航天遥感的周期性监测缺陷;且相比于航天遥感,无人机可以在小范围内高频率的出入进行监测,实时传输现场数据,这对于决策的制定具有重要的意义。……
