Il ruolo di Guido Hauck nello sviluppo teorico della fotogrammetria d'architettura

Guido Hauck's role in the theoretical development of Photogrammetry as applied to Architecture One of the most fascinating subjects of research in the field of Photogrammetry and the practical application of Descriptive Geometry is that concerning the restitution of "non-metrical" Photograms or photograms for which we are unware of the internal orientation. If probable hypotheses - always arbitrary to a certain degree - are not introduced like, for example, the orthogonality of two pairs of straight lines etc., the internal orientation cannot be reconstructed and the usual restitution proceedings cannot be applied. There remain however, a way to obtain the restitution of photograms through the use of two or more homologous images that a little improperly, could be defined as "not oriented", and such an occasion, as can be easily imagined, is offered to us by Projective Geometry. With the discovery of the KERNPUNKTE at the end of the nineteenth century, Guido Hauck laid the foundations for all future research. This article illustrates the importance of his contribution and also gives a synthesis of the various scientific studies done to date.
