step S102, acquiring topographic information of an area to be sprayed with pesticide, wherein the topographic information is divided into three types: flat terrain, uphill terrain, and downhill terrain;

to flat topography, the gesture parameter is used for control unmanned aerial vehicle keep with flat topography is parallel, for uphill terrain, acquire the angle of uphill, according to the angle of uphill is confirmed unmanned aerial vehicle's gesture parameter, to downhill path topography, acquire the angle of uphill, according to the angle of downhill path is confirmed unmanned aerial vehicle's gesture parameter, uphill and downhill path correspond unmanned aerial vehicle's gesture parameter makes the pesticide sprinkler perpendicular to that unmanned aerial vehicle carried uphill or downhill path spray.

When the ascending slope or the descending slope comprises the ascending slope and the descending slope with different angles, the ascending slope and the descending slope with different angles are divided into different areas, and each area corresponds to different attitude parameters.

Step S104, dividing the area to be sprayed with the pesticide into a plurality of areas according to the topographic information, wherein each area only comprises one of the three types of topographic information;

acquiring geographical position information of a boundary of each of the plurality of regions, acquiring a current geographical position of the unmanned aerial vehicle, judging whether the unmanned aerial vehicle enters another region from one region or not according to the current geographical position of the unmanned aerial vehicle, and acquiring attitude parameters of the other region and sending the attitude parameters to the unmanned aerial vehicle if the judgment result is yes.

And dividing the plurality of regions into a plurality of groups, wherein the attitude parameters of each group are the same, and planning the flight path of the unmanned aerial vehicle, namely, after the unmanned aerial vehicle flies all the corresponding regions of one group, flying the next group of regions, so that the continuous adjustment of the flying attitude is avoided. If the regions within the group are not coherent regions, or the regions between the groups are not coherent regions, then no pesticide is sprayed while flying between the incoherent regions.

Step S106, when the unmanned aerial vehicle flies to a preset area in the plurality of areas, obtaining terrain information corresponding to the preset area;

step S108, acquiring attitude parameters according to the terrain information corresponding to the preset area, wherein the attitude parameters are used for adjusting the flight attitude of the unmanned aerial vehicle;

and step S110, sending the attitude parameters to the unmanned aerial vehicle.

For example, the unmanned aerial vehicle may include an attitude calculation unit, which is configured to generate a first output according to the attitude parameter; the attitude control unit is connected with the attitude resolving unit and comprises a PID controller and a robust controller, the PID controller is used for controlling the linear part of the first control quantity of the unmanned aerial vehicle attitude, and the robust controller is used for controlling the nonlinear part of the first control quantity of the unmanned aerial vehicle attitude; and the execution unit is connected with the attitude control unit and is used for driving the execution unit according to the first control quantity to control the attitude of the unmanned aerial vehicle, wherein the first control quantity is obtained according to the first output quantity.

The problem that the pesticide spraying amount is inaccurate due to the fact that the posture of the unmanned aerial vehicle is not considered in the prior art is solved through the steps, so that the posture of the unmanned aerial vehicle is adjusted according to the difference of the terrain, the purpose of controlling the pesticide spraying angle is achieved, and the pesticide spraying accuracy is improved.
