Augmented Reality Applied to the Diagnostics and Fruition of Cultural Heritage

Lucio Colizzi, Andrea Martini, Francesco Chionna

Abstract


The term “Augmented Reality” (AR) is used to define integrated hardware and software technologies, designed to mix video footage taken by a camera with three-dimensional virtual objects. The result is a mix between real reality and virtual reality. Many applications of this technology are being
developed for use in the field of cultural heritage and are being introduced for use in specialized contexts such as in certain phases of the diagnostic process or fruition. The basic algorithmic approach for augmented reality, starts from a video stream analysis that incorporates a real scene. Within the same scene are scattered a set of known geometric images called
“markers”. When the software module in charge of the video flow analysis identifies a marker within the scene, it tries to position it in relation to a reference system integral with the chamber which performs the video shoot, and then replaces it in real time, overlapping with a 3D model achieved through a virtual modeling software. The aim of this article is to evaluate the state of the art augmented reality and then examine several experiments involving its application to cultural heritage.
