A computer-implemented method and system for generating a 3D trajectory to a landing location for an air vehicle

摘要

A system and a method for generating a 3D path from a source to a destination for an aerial vehicle is disclosed. The system comprises several units. A managing unit (102) selects a group of altitude layers including source and destination, generates a 2D horizontal scenario by identifying constraints to avoid at each altitude layer. A path computing unit (104) determines common constraints for the altitude layers of the 2D horizontal scenario and computes a 2D lateral path avoiding common constraints. The managing unit (102) generates a 2D vertical scenario based on a projection of the previously computed 2D lateral path onto the constraints at the altitude layers. The path computing unit (104) computes a 2D vertical path avoiding constraints of the 2D vertical scenario. The managing unit (102) composes 3D waypoints of a conflict-free 3D path according to the 2D lateral path and 2D vertical path.
