Unmanned aerial vehicle collision avoidance method and device, unmanned aerial vehicle and storage medium

Abstract

The invention relates to an unmanned aerial vehicle collision avoidance method and device, an unmanned aerial vehicle and a storage medium. The method comprises the steps that a first unmanned aerial vehicle acquires a second flight parameter broadcasted by a second unmanned aerial vehicle in the process of flying to a first destination; the first unmanned aerial vehicle judges whether collision occurs or not according to the second flight parameter broadcasted by the second unmanned aerial vehicle and the first flight parameter of the first unmanned aerial vehicle; if the collision occurs, the first unmanned aerial vehicle calculates the change speed according to the current quality parameter of the first unmanned aerial vehicle and the quality parameter of the second unmanned aerial vehicle; the first unmanned aerial vehicle flies for a preset time according to the change speed, and the current quality parameter of the first unmanned aerial vehicle is increased; when the first unmanned aerial vehicle judges that no collision occurs according to the second flight parameter broadcasted by the second unmanned aerial vehicle and the first flight parameter of the first unmanned aerial vehicle, the first unmanned aerial vehicle modifies the current speed of the first unmanned aerial vehicle to the initial speed of the first unmanned aerial vehicle; and adjusting the speed direction to the direction pointing to the first destination. The scheme can reduce the cost of the unmanned aerial vehicle.

Description

technical field [0001] The present application relates to the technical field of UAV control, in particular to a UAV collision avoidance method, device, UAV and storage medium. Background technique [0002] At present, UAVs have been widely adopted and applied in many fields, such as relay stations in the communication field, artificial rainfall in the agricultural field, and UAV distribution in the logistics field. In the near future, a large number of unmanned aerial vehicles will be invested in the above or wider fields, and will be encouraged to solve more difficult problems. In this application context, the use of a large number of drones and the resulting collision problems need to be solved urgently. [0003] Regarding the solution to the problem of UAV collision, based on the principle of whether there is a pre-designed avoidance route, there are now two solutions, namely the active avoidance method and the passive avoidance method. [0004] In the active avoidance...
