Dalla realtà al modello e ritorno

More and more accurate methodologies and automatic tools are now available in the field of geometric survey and image processing, constituting a fundamental instrument for cultural heritage knowledge and preservation; on the other side, very smart and precise numerical models are continuously improved, in order to simulate masonry structure mechanical behaviour. Despite the high accuracy and automation level reached by both technologies, the transfer of data between them is not easy and defining the most reliable way to exchange information without data loosing is still an open issue. The analysis of this complex translation process from the very precise information obtainable by the modern survey methodologies for historic buildings, into their very simplified (may be too much) structural schemes is the final aim of this paper.
