Embodiment 1

[0023] Such as figure 1 As shown, the embodiment of the present application discloses a method for controlling the ground imitation flight of a UAV, including: step 100 to step 120 .

[0024] Step 100, acquire the first distance between the UAV and the ground of the operation area, and the value of the adjustment factor.

[0025] During specific implementation, the measurement of the distance between the drone and the ground can be realized by installing sensors such as a distance sensor, an ultrasonic sensor, or a radar on the drone. For example, install an ultrasonic sensor on the UAV, and then determine the first distance between the UAV and the ground according to the time it takes for the ultrasonic waves emitted by the ultrasonic transmitter to meet the ground and then reflected to the receiving end. During specific implementation, other methods may also be used to obtain the first distance between the drone and the ground of the operation area, which is not limited in ...

Embodiment 2

[0034] Such as figure 2 As shown, the embodiment of the present application discloses a method for controlling the ground imitation flight of a UAV, including: step 200 to step 240 .

[0035] Step 200, acquire the first distance between the drone and the ground of the operation area, and the value of the adjustment factor.

[0036] During specific implementation, the adjustment factor may include: at least one of the horizontal flight speed of the drone and the distance between the drone and the top of the plant in the operation area. For the specific implementation manner of obtaining the first distance between the drone and the ground of the operation area and the value of the adjustment factor, please refer to Embodiment 1, which will not be repeated here.

[0037] Step 210, determine the control force for controlling the flight of the UAV according to the first distance.

[0038] During specific implementation, the desired distance between the drone and the ground can b...

Embodiment 3

[0085] Correspondingly, see Figure 4 , the application also discloses a UAV ground imitation flight control device, including:

[0086] The control factor acquisition module 400 is used to acquire the first distance between the drone and the ground of the operation area, and the value of the adjustment factor;

[0087] The first control force determination module 410 is used to determine the control force for controlling the flight of the UAV according to the first distance;

[0088] The control force fine-tuning module 420 is configured to adjust the control force according to the value of the adjustment factor, so that the UAV can fly in imitation of the ground under the effect of the adjusted control force.

[0089] During specific implementation, the adjustment factor may include: at least one of the horizontal flight speed of the drone and the distance between the drone and the top of the plant in the operation area.

[0090]Optionally, when the adjustment factor is th...

Abstract

The application provides an imitated flight control method and device for an unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The problems that in the prior art, an flight control method is limited in applicable operation area and low in safety are solved. The imitated flight control method and device for the unmanned aerial vehicle disclosed in the embodiment includes the following steps that first distance between the unmanned aerial vehicle and the ground of the operation area and a regulatory factor value are obtained; according to the first distance, the flight control force of the unmanned aerial vehicle is determined; according to the regulatory factor value, the control force is adjusted, so that unmanned aerial vehicle conducts imitated flight under the action of the adjusted control force. According to the disclosed imitated flight control method and device for the unmanned aerial vehicle, the distance between the unmanned aerial vehicle and the ground of the operation area serves as a first control factor, through the combination with a regulatory factor, the control force output by the first control factor is fine adjusted, the operation effect can be ensured, and under the conditions that the operation area is complex in topography and landform, the flight safety of the unmanned aerial vehicle can also be ensured.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a method and device for controlling unmanned aerial vehicle's ground imitation flight. Background technique [0002] In agricultural plant protection applications, such as pesticide spraying, drones have huge advantages over other agricultural machinery and have been widely used in recent years. By controlling the UAV to always keep a constant distance from the plant surface, the operation effect can be effectively improved. If the distance between the drone and the plant is too high, it will be difficult to spray the atomized medicine evenly on the plant surface; if the distance between the drone and the plant is too low, it will affect the operating efficiency of the drone. Considering the perspective, the safety factor of UAV operation is also low. Therefore, while improving the operating efficiency and effect of plant protection drones, and at the...
