Problems solved by technology

[0004] The disadvantage of the existing method is: because there are many high-rise buildings in the city, when the UAV is flying in the city, the GPS signal is easily blocked by the high-rise building, so that the GPS signal is prone to multipath effect during transmission, that is, no The GPS signal acquired by the man-machine may have drifted, so the positioning accuracy of the drone is not high. Therefore, a method for positioning the drone is urgently needed to improve the positioning accuracy of the drone

Abstract

The embodiment of the present invention provides a UAV positioning method, device, UAV and storage medium. The UAV is equipped with a camera. The method includes: obtaining the road image collected by the camera, the flying height of the UAV and the attitude information of the camera, wherein the road image includes a lane line area; determining the target lane line area in the road image; according to the flying height, the attitude information and the target lane line area, Calculating the relative distance between the UAV and the lane marked by the target lane area. Applying the technical solutions provided by the embodiments of the present invention can reduce the influence of GPS signal drift in the positioning of the drone, and improve the positioning accuracy of the drone.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a method and device for positioning an unmanned aerial vehicle, an unmanned aerial vehicle and a storage medium. Background technique [0002] In recent years, UAVs have become more and more widely used in cities. For example, UAVs are involved in environmental detection, news reports, agriculture, forestry and plant protection. In the process of performing tasks, UAVs usually need to use unmanned The machine positioning method is used for positioning to obtain its own position information. The position information can be absolute position information or relative position information relative to a certain reference object. [0003] At present, the UAV positioning method is mainly: to obtain the GPS (Global Positioning System, Global Positioning System) signal carrying the position information of the UAV, and to obtain the position of the UAV in the world ...
