Problems solved by technology

[0004] Pre-collect the distribution information of the target vegetation, determine the height of the target vegetation and the size of the canopy, and set the route and speed of the drone to spray pesticides above the target vegetation. However, according to the known target vegetation information, set the route of the drone The method of automatic plant protection and speed requires precise control of the automation settings of the drone, and the need to frequently update the target vegetation information database and the orchard topographic feature database. drug wastage

[0047] see figure 1 , the embodiment of the present invention provides a method for controlling the flight height of a plant protection drone, at the current detection moment, including:

[0048] S101. Obtain the vertical height change of the plant protection drone relative to the target vegetation.

[0049] In this embodiment, the plant protection drone has a built-in millimeter-wave radar, and then the first vertical height of the plant protection drone from the target vegetation below it at the current detection moment and the plant protection drone at the last detection moment are collected by the millimeter-wave radar. The second vertical height of the drone from the target vegetation below it, and send it to the processor of the plant protection drone, and the processor obtains the vertical height of the currently detected plant protection drone relative to the target vegetation according to the first vertical height and the second vertical height Variety.

Abstract

The invention discloses a plant protection unmanned aerial vehicle, a flight height control method and a device thereof, and a storage medium, and the method comprises the steps: obtaining the vertical height change of a plant protection unmanned aerial vehicle relative to target vegetation at a current detection moment; acquiring the relative height change of the plant protection unmanned aerialvehicle relative to the ground at the takeoff moment; obtaining flight information of the current detection moment according to the flight information of the previous detection moment, the vertical height change and the relative height change; wherein the flight information comprises flight of the plant protection unmanned aerial vehicle above the ground, flight of the plant protection unmanned aerial vehicle above target vegetation, flight of the plant protection unmanned aerial vehicle from above the ground to above the target vegetation and flight of the plant protection unmanned aerial vehicle from above the target vegetation to above the ground; and adjusting the current flight height of the plant protection unmanned aerial vehicle in real time according to the flight information so as to realize vegetation plant protection at a preset height away from the target vegetation. Fixed-height flight of the plant protection unmanned aerial vehicle can be controlled, pesticide is accurately and evenly sprayed at the determined height above target vegetation, and plant protection operation is conducted.

Description

technical field [0001] The invention relates to the technical field of agricultural plant protection, in particular to a plant protection drone and its flight height control method, device and storage medium. Background technique [0002] The low cost and high flexibility of UAVs have enabled them to be used in more and more fields, such as the application of plant protection UAVs for automated pesticide spraying in the field of modern agricultural technology. However, most of the plant protection drones can only be used for self-service pesticide spraying on farmland with relatively flat terrain and relatively neat crops. For target vegetation areas with different heights and large intervals, due to the different heights and sparseness of the target vegetation, resulting in When doing self-service pesticide spraying, the spraying accuracy is not high, and the spraying concentration is not easy to control. [0003] Now there are technical flaws: [0004] Pre-collect the di...
