Abstract
A new terrain matching algorithm is presented for use in a passive aircraft navigation system. A sequence of aerial images is matched to a reference digital map of the 3-D terrain. Stereo analysis of successive images results in a recovered elevation map. A “cliff map” is then used as a novel compact representation of the 3-D surfaces. The position and heading of the aircraft are determined via a terrain matching algorithm that locates the unknown cliff map within the reference cliff map. The robustness of the matching algorithm is demonstrated by experimental results using real terrain data.
