The invention relates to the technical field of unmanned aerial vehicle information collection, in particular to an unmanned aerial vehicle
remote sensing information collection method and device, and the device comprises a terminal which generates a navigation
route according to a selection instruction and sends the navigation
route to a controller, the controller that controls the unmanned aerial vehicle to sail according to the sailing
route, the unmanned aerial vehicle provided with a lifting rod and a driving mechanism, a
detector fixedly arranged on the lifting rod and sending out a first
signal when entering the land, a plate body connected to the lifting rod in a sliding mode, and being able to float on farmland crops, and a distance measuring piece that collects a distance value between the
detector and the distance measuring piece when the
detector sends out the first
signal; the controller is further used for controlling the unmanned aerial vehicle to hover when the unmanned aerial vehicle arrives at the collection node and sending a landing instruction to the driving
assembly, and the driving
assembly drives the lifting rod to land in the first direction. The
crop height acquisition device has the effect of acquiring the
crop height of the farmland so as to know the
crop growth condition of the farmland.
