Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0061] The embodiment of the present invention can automatically guide the aircraft to land at the landing point according to the strength of the indication signal sent by the aircraft from the position of the landing point as the signal source, and whether there is a landing point mark in the ground image collected by the aircraft imaging device.

[0062] See figure 1 , is a schematic flow chart of an automatic landing method in an embodiment of the present i...

Abstract

An embodiment of the invention provides an automatic landing method and device and an air vehicle. The automatic landing method comprises the steps of determining the acquired ground image to be a target image when an automatic landing event of the air vehicle is detected; analyzing the determined target image, when the fact that no landing graphic object is included in the target image is determined after analysis, controlling the air vehicle to move in the direction of a signal source of an indication signal according to strength of the received indication signal, acquiring a new ground image after movement of the air vehicle, and after the new ground image is determined to be the target image, executing the step repeatedly until the fact that the target image includes the landing graphic object is determined after analysis; after the fact that the target image includes the landing graphic object is determined after analysis, executing landing control over the air vehicle according to the landing graphic object determined by analysis. By means of the automatic landing method and device, the air vehicle can be guided to land automatically, conveniently, quickly and accurately under the conditions of weak GPS signals, and demands on automatic and intelligent control over the air vehicle of an air vehicle user are met well.

Description

technical field [0001] The invention relates to the technical field of flight, in particular to an automatic landing method, device and aircraft. Background technique [0002] With the development of science and technology, various aircrafts have been manufactured to meet different user needs. Various rotorcraft with imaging functions, especially portable aircraft such as rotor UAV (Unmanned Aerial Vehicle, UAV), have been widely used to perform various tasks due to their ability to provide lightweight, flexible low-altitude, low-speed and hovering flight. Geographical surveying, aerial photography, etc. [0003] Existing rotorcraft is generally operated by the operator through the controller to operate the aircraft to land at a designated position. With the development of technology, the autonomous landing of the aircraft can be realized. The existing autonomous landing method is to use GPS (Global Positioning System, Global Positioning System) Positioning system) satelli...
