A COMBINED STUDY OF ART WORKS PRESERVED IN THE ARCHAEOLOGICAL MUSEUMS: 3D SURVEY, SPECTROSCOPIC APPROACH AND AUGMENTED REALITY

Abstract. The renewed interest, in the context of international museological studies, for historical installations such as museographic devices (able to give shape to a space duly dialoguing with the user), is due today to their communicative immediacy. In recent years the availability of libraries and tools for the use of augmented reality (AR) content has undergone an important increase. AR innovation represents a new method for enhancing the presence visitors into the museum industry despite its use leads to an increase in costs and instrumental investments. In this regard, in a wider work of valorisation and dissemination of archaeological heritage, we are working on the development of an app for tourism purposes. The aim of this paper is the application of some techniques (3D modelling, spectroscopy, virtual reality) to study, record and make available information about archaeological artefacts preserved in the Regional Museum of Lipari (clay masks) and in the National Archaeological Museum of Reggio Calabria (the statue Kouros and the Amphoras). The three-dimensional models produced are well suited to applications of augmented reality for the promotion and dissemination of information on the archaeological /architectural/cultural heritage.

Moreover, the integration of the information about characterization of materials are essential in order to identify both geographic area of provenience and manufacturing historic period. Some pigments or medium, and in general all materials, can be indeed connected to a determinate historic time or to a specific artist; to this particular purpose spectroscopic methods are valid approach for their non-destructive nature.
