Stereo Vision Relative Navigation of Airborne Vehicles

摘要

An automated aerial formation (AAF) system includes an imaging device mounted on an imaging first aircraft that receives reflected energy from an imaged second aircraft. A controller is communicatively coupled to the imaging device and a flight control system of one of the first and the second aircraft. The controller generates a three-dimensional (3D) point cloud based on the reflected energy and identifies a target 3D model in the 3D point cloud. The controller rotates and scales one of a pre-defined 3D model and the target 3D model to find a 3D point registration between the target 3D model and the pre-defined 3D model. The controller steers the flight control system of the one of first and the second aircraft into formation based on the distance and the relative pose determined from the rotating and scaling.
