The invention discloses a control method for all-weather precise landing of unmanned aerial vehicles, which includes: first, the unmanned aerial vehicle executes an instruction to prepare for landing; second, the camera shoots the base station and transmits it to the unmanned aerial vehicle flight control system; Take the white light intensity value A of the image, and compare the white light intensity value A with the set light intensity value K: 3.1), if A>K, select the daytime mode, identify the landing in segments according to the flight height, and finally accurately judge the landing point : 3.2), if the white light intensity value A≤K, then select the night mode, judge the number of signal transmitters in the image and the flicker frequency of the infrared signal, and determine the landing point; 4. Constantly adjust the flying attitude of the drone until there is no The man-machine precisely landed on the landing platform of the base station. By judging the white light intensity value of the image captured by the camera, it is divided into day mode and night mode to ensure that the drone can fly automatically in all weathers and land automatically and accurately, with a high degree of intelligence.
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...
