3D Scan and

Augmented Reality for

Cultural Heritage

Carlo Battini, DICCA - University of Genoa Andrea Caridi, Darts Engineering

Introduction

• 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

Objective of the Presentation

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 frescoes on the other walls

represent scenes from the lives

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

• The four-part vault contains scenes of

Christ's resurrection, the navicella, the

ascension, and Pentecost

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 professional instruments

• Success and optimisation of the touristic experience: – Complete, multimedia and interactive visit assistance ecosystem

– Multilingual and personalised information

– Qualified virtual guide

• Exploitation of mature and promising technologies: – Contactless technologies and image recognition to access services

Opportunities and Results

• Opportunities: – Digitalisation of the tourism resources

– Incentive to the sustainable tourism

– Increasing of the quality of services

– Global vision of the territory and its history, traditions and culture

• Possible results: – Approach young people to culture

– Optimisation of visits planning

– New interests to citizens

– Increase the flux of international tourism

– Creation of an integrated system of culture and tourism

Conclusions

Proposal:

• Obtain a high-resolution 3D scanning of local POIs

• Design Augmented Reality (and, in general, immersive)

experiences using the obtained models

• Implement an innovative project for the valorization of the

territory
