METHOD AND DEVICE FOR AUTONOMOUS LANDING OF UNMANNED AERIAL VEHICLE Russian patent published in 2023 - IPC G06V20/17 G06V10/25 G06V10/56 B64C39/02 G08G5/00 

FIELD: unmanned aerial vehicle (UAV).
SUBSTANCE: controlling autonomous landing of an unmanned aerial vehicle (UAV). At least one auxiliary light source on the image of the landing area and at least one main light source emitting in a colour different from the auxiliary light source, are detected using colour segmentation in the HSV colour space; a group of detected light sources on the image are formed, the generated group of detected light sources is used to identify the location and orientation of the landing area based on the model of the location of light sources and their colours in the landing area known to the device for autonomous landing by solving the PnP problem; and movement towards the landing area is carried out based on the determined location and orientation of the landing area.

EFFECT: increasing the accuracy of autonomous UAV landing under difficult environmental conditions.
