Multimedia digital solutions from image and range based models for ancient landscapes communication

The paper presents the results of an interdisciplinary project which aimed at the dissemination of some archaeological remains producing multimedia contents from multisensor surveyed 3D data. The scope of this application pertained to the use of 3D detailed models as a base for some video-installations with the aim to arouse the visitors’ emotions and improve their museum experience. This work has been applied to the Arch of Augustus located in the archaeological site of Susa and to two ancient Roman marble statues, found in the city of Susa in 1802 and now displayed in the Archaeological Museum of Turin. The Arch of Augustus is in a remarkable state of conservation. Its decorated frieze tells about the peace between the Romans and the Celts but it is difficult to see for visitors at the ground level. A multisensor 3D survey, by means of laser scanning technique and photogrammetric method, made it possible to process a detailed 3D textured model, which provided the base for the creation of a life-size model to be placed in the Museum of Susa on which a designed didactic video map is projected, which explains the meaning of the frieze. The two statues, known as ‘busti loricati di Susa’ and representing two Roman emperors, were surveyed with a photogrammetric method with the aim of processing two 3D models representing the statues before the 19th century restoration, on the basis of archival sources. These models provided the base for a video installation for the museum which simulates a holographic projection and explains the different armour parts highlighting them in sequence. Nowadays modern metric survey technologies allow us to collect and process very detailed 3D models able to satisfy a wide variety of applications field, from specialized representation to didactic final uses in museums exhibitions.
