Abstract
In relation to the latest earthquakes and disasters, the centrality of survey and representation of heritages are some of the most important methods to protect history, to preserve the assets of memory, culture and collective identity. In this scenario photomodelling, one of the contemporary frontiers of research applied to the conservation of Cultural Heritage, leads to the creation of 3D models starting from the simple acquisition of photographs. Laser scanner and structured light 3D scanner are two examples of the several measurements techniques proposed for the digitalization of reality. This new technique is extremely economical and fast. The aim of the research is to understand the full potential ofered by photomodelling and dedicated software, analyzing the reliability of each instrument, with particular attention to freeware ones. An analytical comparison between photomodelling and structured light 3D scanner, tested in the survey of the “Doccione di fontana” of Galleria Nazionale dell’Umbria in Perugia, guarantees a irst measure of the reliability of instruments. Two diferent criteria explained the comparison between 3D models, a spatial one and a surface one, comparing reference and test meshes and extrapolating data relating to the distribution of deviations between elements that compose models. Photomodelling is a suited technique, capable to duplicate and preserve the historical legacy, by promoting an innovative form of communication and spread of culture.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
