Method and device for generating unmanned aerial vehicle route

Abstract

The embodiment of the present application provides a method and a device for generating an unmanned aerial vehicle route. The method comprises the following steps of: generating an initial route of anoperation area of the unmanned aerial vehicle; dividing the operation area into a two-dimensional grid; obtaining two-dimensional coordinate information and point position height information of eachintersection in the two-dimensional grid; determining three-dimensional coordinate information of the plurality of target waypoints corresponding to the plurality of waypoints on the initial route according to the two-dimensional coordinate information and the point position height information of each intersection in the two-dimensional grid; and generating a target route of the operation area according to the three-dimensional coordinate information of the plurality of target waypoints. According to the method and the device for generating an unmanned aerial vehicle route, in this embodiment,the elevation information of each waypoint in the operation area can be obtained in real time and accurately by obtaining the spatial characteristics of the ground terrain, and a target route parallel to the undulating terrain can be generated. When the unmanned aerial vehicle flies according to the target route, the flight altitude of the unmanned aerial vehicle can be quickly judged and adjusted to avoid flight accidents such as crash.

Description

technical field [0001] The present application relates to the technical field of drones, in particular to a method for generating drone routes and a device for generating drone routes Background technique [0002] Unmanned Aerial Vehicle (UAV) is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. UAVs have a wide range of uses and are often used in fields such as agricultural plant protection, surveying and mapping, and video shooting. [0003] Taking the application of drones in the field of agricultural plant protection as an example, when drones perform pesticide spraying and other plant protection operations, they are usually carried out along pre-generated routes. In order to ensure the operation effect, drones are generally required to spray 1 to 2 meters above the crops. However, due to the difference in altitude, the farmland is not level, so it is necessary to constantly adjust the flying height of the dro...

AI Technical Summary

Problems solved by technology

However, acoustic radar and optical radar have defects such as low precision, high power consumption, and easy interference

Once the feedback from the acoustic radar and the optical radar is not timely, it is easy to happen that the drone cannot adjust the flight altitude of the aircraft in time during the flight, which will cause flight accidents such as "bombing"
