Aircraft landing method and device

Abstract

The invention provides an aircraft landing method and device, the method comprising: acquiring the current image of the preset take-off and landing point collected by the aircraft during the landing process; acquiring the matching image of the preset take-off and landing point collected by the aircraft during the take-off phase and the aircraft pose information; perform feature matching on the current image and the matching image to obtain each matching feature point pair; calculate the feature transformation matrix between the current image and the matching image according to each matching feature point pair; obtain the light of the matching image according to the feature transformation matrix The center point is projected to the optical center projection point of the current image; the aircraft is controlled to land to the preset takeoff and landing point according to the coordinates of the optical center projection point. By implementing the present invention, a method for adjusting the landing command of the aircraft is realized, which guides the aircraft to land at the take-off and landing point, improves the landing accuracy of the aircraft, and can adjust the landing command only by successfully matching the collected images, avoiding Real-time tracking of the landing point is achieved, and the difficulty of precise landing of the aircraft is reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft landing method and device. Background technique [0002] With the continuous development of aircraft, the fields of application of aircraft are also becoming wider and wider. The aircraft with flight function can land according to the landing command sent by the terminal. Of course, some intelligent aircraft have the function of automatic return or one-key landing. At present, the common landing method of aircraft is to use GPS (Global Positioning System, Global Positioning System) Assisted landing is to send the GPS coordinates of the target area to the aircraft, and the control system of the aircraft controls the aircraft to land in the target area, and corrects its own landing position according to the GPS coordinates of the target area. However, due to the insufficient accuracy of GPS coordinates and the drift of the aircraft, it is difficult for the aircraft to...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the problem that in the prior art, GPS positioning is used to adjust the landing command of the aircraft to guide the aircraft to land. Due to the lack of accuracy of the GPS coordinates and the drift of the aircraft, the landing error of the aircraft is large and it is difficult to land on a smaller target. The problem of precise landing in the area
