Embodiment 1

[0054] In an embodiment provided by the present invention, the landing sensor in the information collection module is two cameras, specifically a short-focus wide-angle camera and a long-focus camera, so that no The man-machine can continuously collect images of the landing beacons throughout the process for subsequent landing target recognition. The landing target point is an image marking landing sign painted on the landing point and carrying characteristic information.

[0055] The landing point identification module is used to process the images collected by the two cameras, and identify the landing target list in the images. When the UAV is flying at a high altitude, the image output by the short-focus wide-angle camera cannot identify the landing beacon, and only the image output by the telephoto camera can be used to identify and locate the landing beacon on the ground; When the height is lowered, the images taken by the short-focus wide-angle camera and the images tak...

Abstract

The invention discloses an unmanned aerial vehicle autonomous landing system and method and an unmanned aerial vehicle, belongs to the field of computer software, and aims at improving the starting height of unmanned aerial vehicle autonomous landing, improving the autonomous landing accuracy of the unmanned aerial vehicle and avoiding the problems that when autonomous landing is guided completely through a GPS or a single camera, the accuracy is low, and interference is likely to happen in the prior art. According to the invention, at least two landing sensors with different identification ranges, such as cameras with different focal lengths, are arranged to obtain landing target point information and control the unmanned aerial vehicle to land. When the height of the unmanned aerial vehicle is only suitable for a unique landing sensor, a landing target point is identified by utilizing landing related information acquired by the landing sensor; and when the environment where the unmanned aerial vehicle is located can be suitable for at least two landing sensors, landing related information collected by the at least two landing sensors is synthesized, a landing target point is identified, and finally the unmanned aerial vehicle is controlled to land.

Description

technical field [0001] The invention relates to the field of computers, in particular to an autonomous landing system and method for an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] With the rapid development of the UAV industry, the demand for UAV products is not limited to small consumer-grade rotary-wing UAVs, and the demand for large compound-wing manned or cargo-carrying UAVs in various industries is also increasing. The more prominent it is, and the requirements for the autonomy and precision of UAV landing are getting higher and higher. Due to the characteristics of GPS signals being easily interfered by obstructions and low accuracy, UAVs can only rely on GPS position information to achieve the accuracy of fixed-position landing, which cannot meet the current needs for autonomous and precise landing of UAVs. Therefore, in addition to using GPS information to assist in achieving autonomous and precise landing at a fixed locatio...
