stereophotogrammetric recovery
Polytechnic of Bari (Italy)

from the volume 1985-1995: the finalized project
Photogrammetry and protection of the territory

When the photographed surface is not flat, the simple photographic shooting with a camera is no longer reliable, in fact, in the schematic representation (left), the ABCD surface is projected into the flat surface EF. In this case, it is necessary to use a second chamber, whose beam of projecting rays allows the spatial reconstruction of the surface (the points are obtained by the intersection of the corresponding rays).
