Abstract

A collaborative project to understand the interaction of microwave altimeter and scatterometer signals from the ERS-1 satellite with short gravity-capillary waves is being undertaken. Part of this work involves deriving sea surface statistics, by the automated stereo-matching of stereo photographic pairs of water images, based on an adaptive least squares sheet growing algorithm. This approach avoids the manual processing of stereo images, which has until now limited the oceanographic application of stereo photography. Results of the automated matching process are presented together with the high frequency sea surface micro-topography and the corresponding power spectral density for a stereo photographic pair of images obtained by Holthuijsen (1983) from helicopter-mounted platforms.
