Controlling method for all-weather precision landing of unmanned aerial vehicle

Abstract

The invention discloses a controlling method for all-weather precision landing of an unmanned aerial vehicle. The method comprises: step one, an unmanned aerial vehicle executes landing preparation instruction; step two, a camera shoots a base station and transmits information to an unmanned aerial vehicle flight control system; step three, according to a white light intensity value A of a shot image, the flight control system compares the white light intensity value A with a set light intensity value K; to be specific, step (3.1), if the A is larger than the K, a day mode is selected, landing is identified in a segmented mode based on the flight height, and a landing point is determined precisely; and step (3.2), if the A is smaller than or equal to the K, a night mode is selected, the number sent out by a signal transmitting terminal in the image and an infrared signal flicker frequency are determined, and a landing point is determined; and step four, the flight attitude of the unmanned aerial vehicle is adjusted continuously until the unmanned aerial vehicle lands on a landing platform of the base station precisely. On the basis of determination of the white light intensity value of the shot image by the camera, division of the day mode and the night mode is carried out, so that the unmanned aerial vehicle can fly automatically around the clock. Moreover, the unmanned aerial vehicle can land automatically and precisely and the intelligent degree is high.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and in particular relates to a control method for all-weather precise landing of an unmanned aerial vehicle. Background technique [0002] With the development of science and technology, drones are becoming more and more popular in many fields, and more and more market requirements point to drones. It is hoped that drones can replace people to complete dangerous operations and save labor costs. For example, power line inspection and express delivery business. At present, the landing of automatic flying drones cannot be precisely controlled, it is difficult to find base stations on the bottom surface, and the accuracy of landing position judgment is poor. Contents of the invention [0003] The purpose of the present invention is to provide a control method for all-weather precise landing of unmanned aerial vehicles, which solves the technical problems in the prior art th...
