3D Scan and Augmented Reality for Cultural Heritage Carlo Battini, DICCA - University of Genoa Andrea Caridi, Darts Engineering LOGO IMPRESA/ENTE Introduction Objective of the Presentation • 3D scanning makes it possible to obtain high- resolution digital reproductions of monuments, historic buildings and works of art • High-resolution 3D models can be useful, not only in cataloging, preservation and dissemination, but also in the touristic context, thanks to Augmented Reality • In this presentation we will see how 3D scanning and Augmented Reality can work together, also showing a demo on a famous chapel in Florence Santa Maria Novella Basilica di Santa Maria Novella Santa Maria Novella Santa Maria Novella Cappellone degli Spagnoli It is situated at the north side of the green Cloister (Chiostro Verde) It was commissioned by Buonamico (Mico) Guidalotti as his funerary chapel. • 1343 – 1355: built by Friar Iacopo Talenti • 1365 – 1367: Andrea Bonaiuti painted the surfaces • 1540: the chapel was called "Spanish Chapel", because Cosimo I assigned it to Eleonora of Toledo and her Spanish retinue Santa Maria Novella Cappellone degli Spagnoli • The four-part vault contains scenes of • The frescoes on the other walls Christ's resurrection, the navicella, the represent scenes from the lives ascension, and Pentecost of Christ and Saint Peter on the entry wall (mostly ruined due to the later installation of a choir), The Triumph of Saint Thomas Aquinas and the Allegory of Christian Learning on the left wall, and the large "Crucifixion with the Way to Calvalry and the Descent into Limbo" on the archway of the altar wall Santa Maria Novella Cappellone degli Spagnoli Symmetrical Reflective EDM point A B A’ Phase shift D 2D Santa Maria Novella Cappellone degli Spagnoli Santa Maria Novella Cappellone degli Spagnoli • Intensity map multi-hue • Points: 169’820’663 Santa Maria Novella Cappellone degli Spagnoli Santa Maria Novella • Cappellone degli Spagnoli Santa Maria Novella • Cappellone degli Spagnoli Santa Maria Novella • Cappellone degli Spagnoli Santa Maria Novella • Cappellone degli Spagnoli Santa Maria Novella Cappellone degli Spagnoli Santa Maria Novella Cappellone degli Spagnoli AR in Cultural Heritage • Belvedere: – AR geo-localised information on POI – 3D reproduction of the territory • City Centers and Monuments: – POIs’ 3D reproduction in AR – Distributed museum organized in categories • Natural parks and marine reserves: – User GPS position retrieving – AR reproduction of sea floor, flora and fauna • Typical products: – Automatic recognition of products – Commercial and technique information in AR New Frontiers: 3d Tracking • Details’ description • 3d reconstruction Open Sky AR Museums • Information based on: – GPS position – Image recognition – 3d tracking • Superimpositions on the target: – 2d in depth information – 3d objects • Examples: – Architectural details – Fountains – Votive aedicule – Low reliefs – Trompe l'oeil Sustainability • Integrated touristic ecosystem (App + CMS): – Information about museums, POIs and handicraft – Advertisement and m-Marketing => optimisation of visit planning and costs • Tailor made touristic experiences: – Best experience to valorise a particular asset – Development of ad-hoc m-Tourism solutions => maximisation of visit enjoyment • Complementarity between physical and virtual: – Maps, guides, orientation tables – Augmented Reality App => added value and immersive visit Scan 3D + AR An example: Cappellone degli Spagnoli • Frame the 2D plant of the chapel and explore it in 3D, thanks to Augmented Reality! Strengths • ICT solution for a Mobile Smart Tourism: – Valorisation of touristic-cultural resources – Improvement of the accessibility of cultural heritage • Valorisation of reliable data: – Contents created and validated with pro
