OPERATION PLANNING METHOD, SYSTEM, AND DEVICE FOR SPRAYING UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/081896
Kind Code:
A1
Abstract:
An operation planning method for a spraying unmanned aerial vehicle, the method comprising: obtaining 3D spatial information of a target crop area, the 3D spatial information at least comprising a 2D position and altitude, and a plurality of target crops are planted in the target crop area (S401); according to the 3D spatial information, determining a plurality of contour areas in the target crop area, the altitude of each contour area being within one altitude range, and the altitude range within which is the altitude of each contour area does not overlap with altitude ranges within which are the altitudes of other contour areas (S402); determining waypoints of sub-routes in each contour area (S403); and according to the waypoints of sub-routes in each contour area, obtaining waypoints of a route in the target crop area (S404). Therefore, the spraying unmanned aerial vehicle flies within the target crop area according to the route indicated by the waypoints, which complies with terrain features of terrains with different altitudes, reduces energy consumption during operation of the spraying unmanned aerial vehicle, and improves the spraying effect. Further disclosed are an operation system and device for a spraying unmanned aerial vehicle.
