Problems solved by technology

[0004] The ground imitation operation effect of the existing drones is poor, and it is difficult to adapt to the fluctuation of the terrain. Generally, GPS is used to fix the altitude and fly at a constant altitude, or artificially, but the operation is difficult and affected by the line of sight, resulting in Low operating efficiency

Abstract

The invention relates to a terrain-adaptation flight control method and system of a drone. The method includes the steps of firstly, acquiring the real-time relative altitude H of the drone relative to the ground; secondly, acquiring the vertical speed V of the drone, wherein the vertical speed V is the speed using altitude as the benchmark; thirdly, performing data fusion filtering on the real-time relative altitude H and the vertical speed V to obtain a false altitude Hf, and using the false altitude Hf to perform drone altitude control. By the terrain-adaptation flight control method, the flight altitude of the drone can be regulated according to the terrain, a certain distance can be kept between the drone and plants during plant protection, the operation efficiency of the drone and a plant protection spraying effect are increased, and the environment adaptation ability of the drone is increased.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for controlling the ground imitation flight of an unmanned aerial vehicle. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. At present, with the development of science and technology, drone technology is becoming more and more mature, and drones are widely used due to their fast speed and flexible operation. Especially in agriculture and forestry plant protection, agricultural plant protection drones have huge advantages over other agricultural machines. [0003] The operating sites of agricultural plant protection UAVs include plains and undulating terrains. Undulating terrains refer to hilly areas, mountains and terraced fields. It is necessary to keep a constant distance from the crops planted on the job site, that is, the UAV follows the groun...
