Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the relationship between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, if there are descriptions involving "first", "second" and so on in the...

Abstract

The invention discloses a precise landing control method for an unmanned aerial vehicle. The method comprises the following steps that S1, the unmanned aerial vehicle receives a landing instruction and flies to an overhead area of a landing platform; S2, the control terminal starts a positioning sensor group to control the unmanned aerial vehicle to reach a preset vertical area of the landing platform; S3, the horizontal position of the unmanned aerial vehicle is adjusted to be consistent with the landing area of the landing platform till the unmanned aerial vehicle receives a descending instruction of the control terminal; and S4, after it is detected that the unmanned aerial vehicle lands on the landing platform, driving of the unmanned aerial vehicle is stopped, and landing is completed. According to the method, obstacle avoidance and accurate landing are achieved without other auxiliary equipment, and the situation that the unmanned aerial vehicle collides with the landing platform in the landing process, damage is caused, and the service life of the unmanned aerial vehicle is affected can be avoided; and meanwhile, landing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a precise landing control method for unmanned aerial vehicles. Background technique [0002] With the rapid development of drone technology, more and more drones have entered people's lives. UAVs are available day and night, simple in structure, easy to use, low in cost, high in efficiency, and do not have to worry about casualties. Therefore, UAV operations are increasingly favored in high-level environments. It can be used for scene monitoring, meteorological investigation, highway inspection, surveying and mapping, flood monitoring, aerial photography, traffic management, forest fire, etc., and has extremely broad application prospects. . [0003] However, most of the existing UAVs need to rely on external auxiliary signs during the landing process, the landing vibration amplitude is relatively large, and the landing accuracy and efficiency are not high. C...
