Stereo Visualisation of Historical Aerial Photos as a Valuable Tool for Archeological Research

Historical aerial photos can benefit from being viewed in stereo and this can be useful as tool in archeological research. The main reason why stereo images are important is that they give a much better understanding of what is actually in the scene than single photos can. The important factor is the depth cue that helps understanding the content and adds the ability to distinguish between objects such as houses and trees and the ground as well as estimating heights of objects. There are however still challenges but also possibilities that will be discussed.
