Three-dimensional underwater survey: representing the past with new tools for musealization

3D models derived from digital survey techniques have increasingly developed and focused on many fields of application, from urban survey and landscapes to individual objects of cultural heritage. The high detailed content and accuracy of such models makes them attractive and useful for a wide range of purposes. The present paper focuses mainly on the combined use of 3D survey techniques of small and medium objects, using the conventional scanner Artec, with ScubaLibre, a 3D stereoscopic scanner system developed by the Suor Orsola Benincasa University team. This paper presents the results obtained during the underwater excavation of a ship that sank near Marzamemi, southeast Sicily, in the 6th century AD. The data collected and processed offers the basis for new analysis of contexts and artifacts found and the development of new forms of musealization of cultural heritage through innovative technologies for augmented reality and immersive environments.
