The invention discloses a sunlight-induced chlorophyll fluorescence acquisition system based on an unmanned aerial vehicle. The acquisition system comprises a non-imaging hyperspectral spectrometer, a spectrometer optical element, a global positioning system receiver, a laser ranging sensor, the unmanned aerial vehicle, a processor and a battery. The spectrometer optical element is connected with the spectrometer and is a core spectrum acquisition device, and the global positioning system receiver and the laser range finder provide accurate geographic position and height for the unmanned aerial vehicle. According to the system provided by the invention, the vegetation chlorophyll fluorescence with high spatial resolution in a specified area can be flexibly obtained by controlling the unmanned aerial vehicle. By using the system, the defect of insufficient observation area of a foundation acquisition system can be made up, and support verification can be provided for satellite remote sensing inversion data.

    本发明公开了一种基于无人机的日光诱导叶绿素荧光采集系统,该采集系统包括:非成像超光谱光谱仪、光谱仪光学元件、全球定位系统接收器、激光测距传感器、无人机、处理器和电池。光谱仪光学元件与光谱仪连接,是核心的光谱采集装置,全球定位系统接收器和激光测距器提供无人机精准的地理位置和高度。本发明提供的系统,通过操控无人机可以灵活地获取指定区域内高空间分辨率的植被叶绿素荧光。利用该系统可以弥补地基采集系统在观测面积不足方面的缺陷,也可以为卫星遥感反演数据提供支持验证。
