An unmanned aerial vehicle landing system and method based on target platform attitude correction

Abstract

This invention discloses a UAV landing system and method based on target platform attitude correction, relating to the field of UAV landing. The invention selects capture information from non-collinearly arranged target laser emitting devices at the same capture time stamp as valid data sets through a processing unit. Based on the target platform's attitude angle at that target time, the original orientation angles of each laser emitting device are dynamically corrected to obtain the corrected orientation angles. Then, based on the corrected orientation angles and the spatial positions of each target laser emitting device, the three-dimensional position of the UAV relative to the target platform in a horizontal reference frame is calculated. This mechanism unifies laser pointing information to a stable reference frame through attitude correction, fundamentally eliminating the coupling effect of platform roll and pitch disturbances on the positioning reference, and effectively overcoming the positioning distortion problem caused by the reference swaying with the platform in traditional moving platform laser guidance systems.
