Embodiment 1

[0033] Embodiment 1 of the present invention proposes a control method for unmanned aerial vehicle autonomous landing, such as figure 1 As shown, the specific process is as follows:

[0034] Step 10: When it is determined through the first positioning method that the UAV reaches the predetermined area directly above the landing point, and the vertical height of the UAV from the plane where the landing point is located is greater than the preset height, control the UAV to land vertically to the preset height .

[0035] The first positioning method includes: detecting the position coordinates of the UAV through a Global Positioning System (GPS), and detecting the air pressure at the current location of the UAV through a barometer to determine the height of the UAV.

[0036] Among them, the positioning accuracy range of the global positioning system is about 3 meters in the horizontal direction (X, Y direction), and the vertical direction (Z direction) is generally between 5 and...

Embodiment 2

[0058] Embodiment 2 of the present invention proposes a control device 300 for unmanned aerial vehicle autonomous landing, such as image 3 As shown, the device includes a first positioning module 301 , a second positioning module 302 and a control module 303 , and the control module 303 is connected to the first positioning module 301 and the second positioning module 302 respectively. in,

[0059] The first positioning module 301 is used to determine whether the UAV reaches the predetermined area directly above the landing point through the first positioning method, and whether the vertical height of the UAV from the plane where the landing point is located is greater than the preset height;

[0060] The second positioning module 302 is used to determine whether the UAV can be positioned according to the second positioning method at a preset height, wherein the positioning accuracy of the second positioning method is higher than that of the first positioning method;

Abstract

The invention provides a method and apparatus for controlling the autonomous landing of an unmanned aerial vehicle (UAV), wherein the method comprises: controlling the UAV to descend vertically to a preset height when it is determined by a first positioning method that the UAV reaches a predetermined area right above a landing point and the vertical height of the UAV to a plane where the landing point is located is greater than the preset height; when it is determined that the UAV can be positioned at the preset height according to a second positioning method, leading the UAV by the second positioning method to horizontally move to a position right above the landing point, wherein the positioning accuracy of the second positioning method is higher than that of the first positioning method; controlling the UAV to vertically descend and land on the landing point according to the first positioning method and the second positioning method. The method and apparatus can make the UAV reach the predetermined landing point accurately and safely in the autonomous landing process by using different positioning methods.

Description

technical field [0001] The invention relates to the technical field of autonomous flight of unmanned aerial vehicles, in particular, to a control method and device for autonomous landing of unmanned aerial vehicles. Background technique [0002] At present, unmanned aerial vehicle (UAV) technology has a significant effect on electric power inspection. It is not limited by terrain and landform, and is especially suitable for line inspection in steep mountainous areas and landforms with many rivers. The airborne high-definition camera equipment can locate and monitor the transmission line online and send back the live situation in time, which is conducive to the discovery and elimination of line defects and major hidden dangers. The inspection efficiency is greatly improved, and a lot of manpower and material resources are saved. It is also particularly important to recover drones through accurate positioning. [0003] The existing navigation methods of UAVs in the landing pro...
