Research on Vision Positioning Algorithm of UAV Landing Based on Vanishing Point

Regarding the visual positioning of the autonomous landing of UAVs, this paper proposes a pose calculation method that uses the spatial geometric characteristics of the vanishing point of parallel lines and the principle of camera imaging to calculate the position and pose of the UAV. At the same time, a new symbol judgment mechanism is added to the original method to improve the accuracy of pose estimation and provide a new solution for UAV landing pose estimation.
