The authentication and sustainability of cultural heritage monuments are of great importance due to their uniqueness. Recent accidents and natural disasters have taught us that all monuments, even the most protected such as the cathedral Notre-Dame de Paris, can be destroyed by an unexpected event. For these reasons, it is of paramount importance the creation of a monument database containing fusion data not only of the accurate 3D model and precise representation of the artifacts/monuments but also about the condition and procedures of restoration and preservation and the structural health of the antiquities by means of quantitative non-destructive techniques, such as Infrared Thermography. The 3D model of a monument would guarantee the accurate restoration of the monument in case of a catastrophic disaster, while the 3D model of an artifact together with the entire related metadata would provide a digital identity, therefore guaranteeing the sustainability of the item. Also, in case of a movable artifact, it will be a useful tool towards the validation / authentication of the artifact in case it is damaged or missing.
This study aims in developing an advanced 3d digitization and nondestructive evaluation methodology that will serve as a baseline to advanced Augmented Reality (AR) and Virtual Reality (VR) applications of sites with archaeological interest in order to enhance not only the on-site experience for the visitors and the visitors via internet but as well to provide a useful tool for the preservatives, through improved supervision processes during maintenance. To this regard, a consolidated database is being created by the use of the best combination of state-of-the-art techniques of 3D digitization not only of the archaeological site itself but also of archaeological findings that at this time are presented in the museum. All the aforementioned data, created a database of the monument that aims to provide an augmented and virtual experience which is beyond the state of the art not only to the visitors but also to the preservative teams and it will help definitely towards the sustainability of the monument.
