Geomatics Techniques for Cultural Heritage Dissemination in Augmented Reality: Bronzi di Riace Case Study

Abstract

The Riace Bronzes are two full-size bronzes cast around the 5th century BC, located at the ‘Museo Archeologico Nazionale della Magna Grecia’ in Reggio Calabria; they truly represent significant sculptural masterpieces of Greek art in the world due to their outstanding manufacture. This paper describes the methodology for the achievement of a 3D model of the two sculptures lead by the Geomatics Laboratory of the Department of Civil, Energetic, Environmental and Material Engineering (DICEAM) of the Mediterranean University of Reggio Calabria. 3D modeling is based on the use of imaging techniques such as digital photogrammetry and computer vision. The achieved results demonstrate the effectiveness of the technique used in the cultural heritage field for the creation of a digital production and replication through 3D printing. Moreover, when considering renewed interest in the context of international museological studies, augmented reality (AR) innovation represents a new method for amplifying visitor numbers into museums despite concerns over returns on investment. Thus, in order to further valorize and disseminate archaeological heritage, we are developing an app for tourism purposes. The created app allows the user, in real time, to obtain additional information on the object of investigation, even allowing them to view the 3D model in AR.
