Abstract

Machines that have been developed to determine the topography of a region from stereo-pair photographs are subject to correlation errors resulting in incorrect elevation calculations. In this paper, the determination of the location of the peak of the correlation function of two similar arrays of picture elements is modelled as a parameter estimation problem. The Cramer-Rao lower bound is considered as a possible tool for predicting the magnitude of correlation errors. Preliminary simulation results are included.
