Embodiment Construction

[0023] The invention provides a vision-based UAV return and landing method, which can realize automatic return based on a vision module. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to make it easier to understand and grasp.

[0024] Vision-based UAV return and landing methods, such as figure 1 As shown, the UAV includes a vision module. The vision module is an ultra-wide-angle single lens or composed of multiple cameras for recording images along the way. During the flight, the UAV uses the vision module to record the feature points along the flight. figure 2 As shown in the image feature trajectory, when the UAV returns to the voyage, the real-time image is obtained through the vision module, and the real-time image is compared with the feature point distribution of the image frame in the image feature trajectory to determine and adjust its own flight. In a preferred embodiment, the u...

Abstract

The invention discloses an unmanned plane return flight landing method based on visual sense. An unmanned plane comprises a visual sense module, which is formed by a super wide angle single lens or a plurality of cameras. During the flying process of the unmanned plane, the visual sense module is used to record characteristic points of a flight route to form an image characteristic track. During the return flight of the unmanned plane, the visual sense module is used to acquire a real-time image, and the own flight is determined and adjusted by comparing the characteristic point distribution of the real-time image and the characteristic point distribution of the image frame of the image characteristic track. The unmanned plane return flight landing method based on the visual sense is advantageous in that automatic return flight based on the visual sense module is realized; safe landing is realized by adopting optical flow; obstacles in a landing area are avoided; the safety performance of the unmanned plane is improved, and the accident rate of the unmanned plane is reduced.

Description

technical field [0001] The invention relates to a method for returning and landing an unmanned aerial vehicle, in particular to a method for returning and landing an unmanned aerial vehicle based on vision. Background technique [0002] The return of the UAV is generally controlled manually by the remote control terminal or automatically returned by the automatic return mechanism. The automatic return is generally realized after the return course is determined according to the satellite positioning system. [0003] In the prior art, during the flight of the UAV, the sensor components fail, the satellite positioning system has no signal, etc., and the return course cannot be determined. At this time, the remote control terminal and the automatic return mechanism cannot achieve effective return. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art that the UAV cannot determine the heading and re...
