Visiting Heritage Sites in AR and VR

Abstract

Advances in digitization technologies have made possible the digitization of entire archaeological sites through a combination of technologies, including aerial photogrammetry, terrestrial photogrammetry, and terrestrial laser scanning. At the same time, the evolution of computer algorithms for data processing and the increased processing power made possible the combination of data from multiple scans to create a synthetic representation of large-scale sites. Finally, post-processing techniques and the evolution of computer and mobile GPUs and game engines have made possible the exploitation of digitization outcomes to further scientific study and historical preservation. This route was opened by the gaming industry. In terms of research, the exploitation of these new assets in conjunction with new visual rendering technologies, such as virtual and augmented reality, can create new dimensions for education and leisure. In this paper, we explore the usage of large-scale digitization of a heritage site to create a unique virtual visiting experience that can be accessed offline in VR and AR and on-site when visiting the archaeological site.
