The invention relates to the technical field of plant measurement, and provides a multi-angle chlorophyll fluorescence measurement system and method based on unmanned aerial vehicle remote sensing, the system comprises an unmanned aerial vehicle, an undercarriage and an acquisition probe, the undercarriage comprises a plurality of strip-shaped frames which are uniformly distributed in the circumferential direction, each strip-shaped frame is provided with an extension piece in a clamping manner, and the extension pieces are connected with the unmanned aerial vehicle; each extension piece is provided with a ground supporting rod with adjustable length; a protective cylinder is arranged on the unmanned aerial vehicle body, one end of the protective cylinder is open and is provided with an adaptive cover plate, and the acquisition probe is arranged on the cover plate through a probe bracket in an angle adjustable manner; when the unmanned aerial vehicle lands, the whole undercarriage is unfolded, meanwhile, the cover plate is switched to the protection station so that the collection probe can move into the protection barrel, the dust blocking effect is achieved through the protection barrel, then the unmanned aerial vehicle is controlled to gradually land till the unmanned aerial vehicle keeps a certain height from the ground, and then each ground supporting rod extends to the end to make contact with the ground falling point. And finally controlling and stopping propellers of the unmanned aerial vehicle to realize stable landing.

    本发明涉及植物测量技术领域,提供了一种基于无人机遥感的多角度叶绿素荧光测量系统及方法,包括无人机、起落架以及采集探头,所述起落架包括多道周向均匀分布的条形框,每道所述条形框上均卡设有伸展件,每个所述伸展件上均设有长度可调的撑地杆;所述无人机机体上设有防护筒,所述防护筒一端敞口且设有适配的盖片,所述采集探头通过探头支架角度可调式设于盖片上;无人机降落时,起落架整体展开,同时,盖片切换至防护工位使得采集探头移至防护筒内部,通过防护筒起到挡隔灰尘的作用,然后操控无人机逐渐降落至与地面保持一定高度,接着每根撑地杆伸长至端部与地面落点接触即可,最后操控关停无人机螺旋桨实现平稳降落。
