PHOTOGRAPHIC STEREOSKETCHES MADE AS MEASURING STEREOGRAMS FOR CARTOGRAPHIC-GEOLOGICAL PURPOSES

Summary

The article presents a method of making photographic stereosketches used as a photogrammetric survey. For this purposes, a fragment of terrain (lanslide, exposure) with the sygnalled points should be photographed, using the same camera, from two positions: left position – S1 and right position Sp Then, the length of the basis (i.e. the distance between S1 and Sp) should be measured from both positions, as well as horizontal angles (beta) and vertical angles (gamma), measured to the signals in the terrain, be read off. The signalled points and their radial displacements are then presented on vertical projection plane po. The transformation of the left and right photographic stereosketches into a normal photogrammetric survey is made by co-ordinating the points signalled and presented as those with radial displacements by means of analytical and graphical methods (Figs 1–4).
