Digital models of architectural models: from the acquisition to the dissemination

Antiquities and works of art preserved in museum collections represent an invaluable evidence of our history. A proper three-dimensional metric survey and digitisation of these assets (which are intrinsically fragile and for this reason need a continue and careful documentation) allow to increase significantly their resilience and they offer a valid contribution for the management of these objects belonging to movable heritage. This work takes place during a research experience carried out in the framework of B.A.C.K. TO T.H.E. F.U.T.U.RE. (BIM Acquisitions as Cultural Key TO Transfer Heritage of ancient Egypt For many Uses to many Users REplayed) during which a collection that consists of fourteen wooden models belonging to Museo Egizio of Torino has been digitised using both imagebased and range-based modeling techniques. In addition to geometric and radiometric data, provided by textured model, information of various nature related to the considered asset has been integrated. The main aim of the research, starting from the digital 3D models, is the creation of threedimensional databases (with alphanumeric and multimedia informations about historical, artistic and management aspects), useful for several purposes: 3D visualisation, communication, dissemination and data management. In this paper 3D metric acquisition strategies have been evaluated and the followed methodology as regards data enrichment have been illustrated.
