The Taormina Theater: The Digital Survey System of Knowledge Open in Time

Abstract

In Sicily there are 19 show venues including ancient theaters and theatrical architectures. Many of these structures are fully functional and subject to visitor flows such as the theater of Syracuse and that of Taormina. They are object of interest and curiosity, revealed in the eighteenth century during the grand tour by travelers and landscape painters, in the last twenty years they have become reasons for study in various scientific areas as from acoustics to archeology, always passing through digital surveying. Studied through classical photogrammetry, structure from motion (SFM), 3D laser scanner, their representation as well as by increasingly refined and detailed two-dimensional graphics, makes use of 3D representations and techniques of virtual reality (VR) and augmented reality (AR). Due to their particular geometry, the need for studies and research is considered essential to deepen the methods of the surveys and plan their developments. Examples and problems for the archaeological survey are reported with the aim of critically evaluating the current state of the art of 3D survey, the potential and possible future developments, in the present study the results obtained for the survey of the Taormina theater (ME) and in-depth analysis of the versure environments.
