A UAV-assisted landing platform and landing method based on machine vision

Abstract

The invention provides a machine vision-based unmanned aerial vehicle auxiliary landing platform and a landing method thereof, comprising a bearing base, a driving guide rail, a slider, a guide plate, a projection lamp, a reticle, a monitoring camera, a main guide lamp, an auxiliary guide Lamp and driving circuit, the reticle is embedded in the upper end surface of the bearing base, the projection lamp is embedded in the bearing base, the driving guide rail is wrapped outside the bearing base, the rear end surface of the guide plate is hinged with the front end surface of the slider, and the rear end surface of the slider is connected with the driving slider. The rails are slidably connected, the front end face of the guide plate is provided with a monitoring camera, the upper end face is provided with an auxiliary guide light, the main guide light is embedded in the upper end of the bearing base, and the drive circuit is embedded in the bearing base. Its use method includes two steps: system prefabrication and landing guidance. The invention can effectively meet the needs of the use of a variety of different structural sites; in operation, it can realize efficient and convenient landing guidance for the unmanned aerial vehicle, and has high guidance and positioning accuracy, convenient and reliable operation, and good networking operation ability.

Description

technical field [0001] The invention relates to a machine vision-based drone-assisted landing platform and a landing method thereof, belonging to the technical field of drones. Background technique [0002] At present, with the promotion and popularization of UAV technology, UAVs have been widely used in many fields, but in actual use, in the process of landing UAVs, in order to improve the accuracy and reliability of landing At present, the landing site is mainly selected, positioned and identified through satellite positioning and the drone's own camera system. However, in actual use, it is found that due to the influence of satellite communication signals and wireless control signal stability factors, the accuracy of drone landing control Relatively low, coupled with the influence of airflow, it has led to an increase in the difficulty of current UAV landing control, which has seriously affected the reliability and stability of UAV equipment. [0003] Therefore, in view ...

[0002] At present, with the promotion and popularization of UAV technology, UAVs have been widely used in many fields, but in actual use, in the process of landing UAVs, in order to improve the accuracy and reliability of landing At present, the landing site is mainly selected, positioned and identified through satellite positioning and the drone's own camera system. However, in actual use, it is found that due to the influence of satellite communication signals and wireless control signal stability factors, the accuracy of drone landing control Relatively low, coupled with the influence of airflow, it is more difficult to control the current UAV landing control, which seriously affects the reliability and stability of UAV equipment.
