Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0021] see Figure 1A with Figure 1B , which is a schematic diagram of the application scenario of UAV positioning in the embodiment of the present invention:

[0022] Figure 1A A schematic diagram of the flight state of a UAV is shown in . In this flight state, the roll angle and pitch angle of the UAV are both 0 degrees. Since the roll angle θ and the pitch angle Ф are both 0 degrees, so Figure 1A Not marked in . Among them, the pitch angle Ф is the angle in the left and right directions, and the roll angle θ is the inc...

Abstract

The invention provides a positioning method of an unmanned aerial vehicle and a device. The unmanned aerial vehicle comprises a first sensor. The method comprises the following steps: acquiring the motion speed of the unmanned aerial vehicle at the first coordinate system via a first sensor; determining the motion speed of the unmanned aerial vehicle at the second coordinate system according to the motion speed of the unmanned aerial vehicle at the first coordinate system; and determining the horizontal position of the unmanned aerial vehicle relative to the take-off point according to the motion speed of the unmanned aerial vehicle at the second coordinate system. Therefore, the speed of the unmanned aerial vehicle and the horizontal position relative to the take-off point can be measured precisely via the first sensor, and the unmanned aerial vehicle can be positioned rapidly and precisely.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a positioning method and device for an unmanned aerial vehicle. Background technique [0002] With the development of network communication technology, drones have also been widely used. The unmanned aerial vehicle is a kind of unmanned aerial vehicle operated by radio remote control equipment or its own program control device. It has a wide range of uses, but how to locate the unmanned aerial vehicle in flight has become a key problem. [0003] In the prior art, the UAV positioning method generally adopts a global positioning system (Global Positioning System, GPS) for positioning. If there is no GPS signal, the positioning of the drone cannot be completed. Therefore, the UAV positioning method in the prior art has a small application range, low positioning accuracy, and slow positioning speed. Contents of the invention [0004] The invention provides a UAV po...
