Abstract

This paper describes the application of a stereomatching algorithm to the problem of geo-rectifying a set of declassified military air photos over Cat Tien National Park, Vietnam. A disparity model, related to topographic features, is first built and then co-registered to a geo-referenced elevation model to provide the transformation required to correct the air-photos. Accuracy of results is assessed through correlation coefficients between retrieved disparities and known elevations.
