Abstract: A control method includes obtaining three-dimensional (3D) spatial information of a target crop area planted with a plurality of target crops; determining spraying control information based on the 3D spatial information; and controlling a spraying unmanned aerial vehicle (UAV) to perform spraying on the plurality of target crops based on the spraying control information. The spraying control information includes a spraying mode for controlling the spraying UAV to perform spraying on one target crop of the plurality of target crops, and the spraying mode includes a flight mode.
