Stereophotogrammetric techniques were used for a study of snow avalanches. The contour lines of the avalanche slope were mapped from stereo-photographs taken before and after the occurrence of the avalanche. The outline of the avalanche front at cert

This paper discusses the various formulas in use for the computation of tree heights from parallax measurements in aerial photographs. The errors in the computed tree heights, caused by the various error sources, are derived for three different camer

Stereophotogrammetry was used for the first time to measure the local particle velocity vector and its turbulent components in two-phase solid-gas flow in a 10 cmc. I.D. vertical pipe. From the image counts on the stereophotographs, it has also been

The results in this paper have shown how precise geometrical information can be obtained from photographs taken with a camera that is not specifically designed for photogrammetric purposes. By referring the image coordinates to a system of targets in
