Embodiment Construction

[0089] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0090] In the prior art, the existing aircraft obstacle avoidance method usually adopts constructing a local map, so as to realize the trajectory planning of the aircraft obstacle avoidance according to the local map. However, since it takes a certain amount of time to construct a local map, the aircraft cannot avoid obstacles quickly and in real time during the obstacle avoidance process...

Abstract

The invention discloses an aircraft obstacle avoidance method. The method comprises the following steps: acquiring point cloud data in an advancing direction of an aircraft; performing gridding processing on the point cloud data to obtain gridding point cloud data; determining an aircraft obstacle avoidance mode according to the gridding point cloud data; and adjusting flight parameters of the aircraft according to the aircraft obstacle avoidance mode. In the obstacle avoidance process of the aircraft, an environment map does not need to be constructed, the obstacle avoidance mode of the aircraft can be determined only by obtaining the point cloud data in the advancing direction of the aircraft, and obstacle avoidance of the aircraft is achieved according to the obstacle avoidance mode of the aircraft, that is, compared with the prior art, the method provided by the invention does not need to consume a certain time to construct a local map, the obstacle avoidance time of the aircraft is shortened, the quick and real-time obstacle avoidance of the aircraft is realized, and the obstacle avoidance efficiency of the aircraft is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft obstacle avoidance method and device. Background technique [0002] Aircraft are in a stage of rapid development, especially drones. With the advancement of UAV technology, new technologies are continuously introduced, the number of sensors in UAVs has been greatly improved, and the number of flight tasks is also increasing. [0003] As the application fields of UAVs continue to increase, the task complexity and safety and reliability requirements are further enhanced. At present, drones are very mature in flight control, and have expanded more new application scenarios than before, such as: power inspection, emergency rescue, urban logistics and even manned aviation. In the face of ever-increasingly complex scenarios, the safety and reliability requirements of UAVs have also been greatly increased under the premise of ensuring the completion of tasks. At present,...
