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

Embodiment Construction
[0022] Such as figure 1 As shown, the aircraft 1 below is provided with a camera 10, and the camera 10 can include a camera 11 with the lens facing down as the first camera, a camera 12 as the second camera with the lens facing the front and bottom, and a camera 12 as the second camera with the lens facing the rear and the bottom. The camera 13 of the camera, preferably, three cameras are linearly arranged and located in the same vertical plane, and each camera is provided with a filter, wherein the filter is set to pass through light of a predetermined wavelength, such as infrared rays, etc. . When the aircraft 1 is flying straight ahead, the camera 12 can face forward and downward while the camera 13 can face rear and downward. The angle between the camera 12 and the camera 11, the angle between the camera 13 and the camera 11 are preferably set to be equal, the angle can be selected in the range of 0 to 90 degrees, further preferably, the angle can be Choose from the rang...

The invention provides an aircraft moving and landing system and a method for using the system to move and land an aircraft. The aircraft mobile landing system provided by the invention includes a camera device installed on the aircraft and a landing target installed on the landing platform. The landing target is provided with a light source that emits light of a predetermined wavelength. The control device controls the light source to strobe according to a predetermined frequency, and the camera The device includes a filter that transmits light of a predetermined wavelength, a first communication module is provided on the landing platform, and a second communication module that communicates with the first communication module is provided on the aircraft. The invention has the advantage that the aircraft can move and land stably, and the landing process is less affected by external interference.
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 ...
