Aircraft mobile landing system and mobile landing method

Abstract

The invention provides an aircraft mobile landing system and an aircraft mobile landing method using the system; the aircraft mobile landing system comprises a camera arranged on the aircraft and a landing target arranged on a landing platform; the landing target is provided with a light source sending lights with the preset wavelength; a controller controls the light source to flash according to a preset frequency; the camera comprises a filter sheet allowing the light with the preset wavelength to pass; the landing platform is provided with a first communication module; the aircraft is provided with a second communication module communicating with the first communication module; the system and method allow the aircraft to stably land in mobile, and the landing process has small external interferences.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a mobile landing system and a mobile landing method for multi-axis aircraft. Background technique [0002] At present, aircrafts such as multicopters usually land automatically through computer vision systems, use cameras to obtain images of landing targets, identify and align landing targets through computer vision, and land safely on landing platforms. Usually, computer vision uses color or shape to distinguish and identify objects. It is common to use infrared light sources as identification targets. However, under sunlight, it is susceptible to interference from ambient infrared rays, causing computer vision to be interfered by multiple identification objects when identifying targets. Furthermore, when the multicopter is close to the landing target, due to airflow disturbance or external interference, etc., the fuselage of the multicopter may shake, which in turn causes the ...

Problems solved by technology

Usually, computer vision uses color or shape to distinguish and identify objects. It is common to use infrared light sources as identification targets. However, under sunlight, it is susceptible to interference from ambient infrared rays, which leads to interference from multiple identification objects when computer vision identifies targets.

Furthermore, when the multicopter is close to the landing target, due to airflow disturbance or external interference, etc., the fuselage of the multicopter may shake, which in turn causes the camera to shake, and it is difficult for the computer vision system to identify and align the shaking landing target image. making it impossible to land stably on the landing platform

Further, when the landing target is on the moving landing platform, the landing target itself is also shaking, thus further increasing the landing difficulty of the multicopter, which may cause accidental damage to the aircraft
