Abstract

Draping an aerial photograph over known elevation data enables simulated views of the same area from an arbitrary point of view. Doing this in software for a high resolution image could take days. Commercial hardware is available to do this in hours. This paper will present a method for doing it in seconds. Similarly, comparing two images of the same target which have been taken from different altitudes or directions requires one or both images undergo perspective correction. Perspective correction is a computation intensive process made even more complex when the images cover mountainous terrain. This paper will describe hardware that can in real time eliminate the perspective difference between two such images.
