Aircraft landing method and device

Abstract

The invention provides an aircraft landing method and device. The aircraft landing method comprises the steps of obtaining a current image of a preset take-off and landing point collected by an aircraft in the landing process; obtaining a matching image of the preset take-off and landing point collected by the aircraft in the taking-off stage and attitude information of the aircraft; matching characteristics of the current image and the matching image to obtain each matching characteristic dot pair; according to each matching characteristic dot pair, calculating a characteristic transformationmatrix between the current image and the matching image; according to the characteristic transformation matrix, obtaining an optical center projection point, projected to the current image, of an optical center point of the matching image; and according a coordinate of the optical center projection point, controlling the aircraft to land to the preset take-off and landing point. According to theaircraft landing method and device, an an aircraft landing instruction adjusting method is realized to guide the aircraft to land to the take-off and landing point so that the aircraft landing accuracy is enhanced; only by successfully matching the collected images, the landing instruction can be adjusted to avoid real-time tracking of the landing point and reduce the aircraft accurate landing difficulty 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
