Abstract :
A novel vision-based navigation algorithm is proposed. The gray levels of two images, together with a Digital Terrain Map (DTM), are directly utilized to define constraints on the navigation parameters. The feasibility of the algorithm is examined both under a simulated environment and using real flight data.
