Abstract: Restrictions of conventional techniques for assisting navigation of a vertical takeoff and landing vehicle in circumstances where there is a possibility of the view being obscured, can be overcome by using a three-dimensional model in combination with image processing to determine which segments of a landing zone are visible and which segments are obscured. A pilot is provided with a view of the landing zone that is a combination of live images and simulated segments from the three-dimensional model. Whereas conventional techniques focus on generating better simulated views, an implementation of this invention includes generating a view of an obscured landing zone that includes live imager. Fusing live imagery with other sensor information to generate a view allows the pilot to use a much real information as possible, and facilitates increased pilot confidence that the pilot can proceed and execute a successful landing.
