Paper Abstract

3-D data of wave patterns generated by a ship or ship model in running water are used for the computation of the wave resistance. The results are suitable to optimize the ship design. A series of investigations was carried out to determine the wave heights photogrammetrically. The water surface around a test model in an open channel was photographed with four simultaneously released partial metric cameras. The visibility of the wave surface was improved by scattering small particles onto the water. Stereopairs were measured on an analytical plotter in order to obtain a 3-D point cluster. Digital object models and various follow-up products such as perspective representations, contour maps and profiles were derived with the DTM program system HIFI-88.
