VIRTUAL REALITY FOR HISTORICAL ARCHITECTURE
2019
Abstract. This article shows a first step in the development of an immersive virtual tour of the Cathedral of Palermo, entering the fields of Digital Cultural Heritage and Edutainment. Its purpose is to help people to gain knowledge about the site, highlighting the complex stratifications that have characterized its history.The development of the project has been possible thanks to different phases of work: surveys were initially carried out by laser scanning, then assembled and processed to obtain the 3D model of the current state; at the same time, the model of reconstruction was processed in several phases, based on historical, archival and iconographic sources; both models were, later, …
The ‘Archaeological Map of Lilybaeum’
2021
The ‘Archaeological Map of Lilybaeum’ is the result of the long-standing scientific cooperation in Marsala between Palermo and Hamburg Universities. This paper investigates the various methods of field research used to gather the necessary data for the archaeological map of ancient Lilybaeum. There will be a particular focus on the topographic survey and photogrammetric aerial survey by Remotely Piloted Aircraft System (RPAS) conducted in the years 2017–2019. The aim of the work is to highlight the impact of the results on already existing research hypotheses and the ways in which the resulting map enhances our knowledge of the ancient city of Lilybaeum.
3D survey and modelling of the main portico of the Cathedral of Monreale
2018
3D survey and modelling of Cultural Heritage allow to store a great deal of 3D data that can be managed for different purposes. 3D models can be used for documentation, restoration and knowledge of historic architectures and monuments. In this work, a 3D survey of the main portico of the Cathedral of Monreale (Palermo, Italy) was carried out. The paper presents the data acquisition process and the 3D modelling phase. The work is aimed to reconstruct a 3D model that could be used also to set up an HBIM (Heritage or Historic Building Information Modelling) of the main portico. The result of this study could be considered as a first test to implement an HBIM platform for the whole monumental c…
Ricostruzione virtuale dei resti archeologici: sperimentazione di approcci integrati innovativi per lo studio e la valorizzazione dell’area sacra del…
2022
Il progetto di cui si presentano i risultati è rivolto all’ambito delle Scienze applicate al Patrimonio culturale e, nella fattispecie, all’applicazione di metodologie e tecnologie innovative di ricostruzione virtuale di supporto allo studio, alla valorizzazione e alla fruizione innovativa dei beni archeologici. Esso ha richiesto, per l’acquisizione delle competenze necessarie alla sua conduzione, lo svolgimento di uno stage presso la Virtutim srl in Roma, per la formazione all’uso delle tecniche di rilievo 3D e dei software di grafica e modellazione virtuale con cui sono stati realizzati i contenuti multimediali presentati di seguito, nonché un periodo di studio all’estero, presso l’Instit…
The Virtual Reconstruction of the Aesculapius and Hygeia Statues from the Sanctuary of Isis in Lilybaeum: Methods and Tools for Ancient Sculptures’ E…
2022
Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawi…

Abstract · Topographic Atlas of Soknopaiou Nesos : 3D Survey of the town. Methodologies of data acquisition and detection systems for the archaeological documentation (Season 2019) · The article concerns the topography research project of the city of Soknopaiou Nesos in Fayyum. In particular, the goal of the project is the realization of a digital knowledge and conservation plan of the entire archaeological the site using innovative digital survey techniques and then the creation of a topographic atlas necessary for the realization of a ceramic intrasite survey of the site. In particular, this article illustrates the methodologies adopted for the 3D survey and the results achieved in the 20…
3D mosaics survey: analysis of photogrammetric/computer vision approach in a metrological context
2016
The goal of the paper is evaluate photogrammetric/computer vision approach in a metrological context for 3D mosaics survey. The aim of the mosaics survey is the production of a full-scale representation (scale 1:1) useful for the documentation and for the restoration processes. In order to evaluate the optimal photogrammetric/computer vision workflow in this work three different surveys have been done for three mosaics with different size and location. Two of these are stored at Regional Archaeological Museum “Antonino Salinas” in Palermo (Italy) and the other one is stored at Regional Archaeological Museum “Baglio Anselmi” in Marsala (Italy). The research has allowed to show the potentiali…
Mappe stellari e geometria sacra nel disegno delle città medioevali di Sicilia. Un’ipotesi archeoastronomica su Erice
2020
Already in his studies on the Middle Ages cities E. Guidoni suggested the possibility of an urban design governed not only by precise astronomical alignments, but by a figurative conception, of a zoomorphic or anthropomorphic type, whose aim was to reproduce on the ground the zodiacal constellations. The envelopes and sinuosities of the plots that distinguish the medieval cities would be dictated by an iconographic program in which certain emergencies (churches, towers, domes) and the main connection roads would be arranged in a mirror-or perspective-view of the celestial maps with respect to certain observation points at the meridian or on the horizon of the place. Some examples would be e…
THE MAIN PORTAL OF THE CATHEDRAL OF MONREALE: FIRST GEOMETRIC ANALYSIS AND INTERPRETIVE ASSESSMENT OF ARCHITECTURAL FEATURES
2017
Abstract. Nowadays, 3D documentation of architectural assets is becoming a demanding task for the valorisation of Cultural Heritage especially after a restoration project. The 3D documentation can be used for detailed analysis of specific elements, for monitoring the state of conservation and for valorisation actions. The paper describes the results of the 3D close-range photogrammetry survey of the main portal of the Cathedral of Monreale (Palermo, Italy). The Cathedral is one the most important monumental complexes in Sicily that, for its high historical and artistic importance has been inscribed on UNESCO’s World Heritage List since 2015. The main portal of the Cathedral has been recentl…
AN EXPERIMENTAL WORKFLOW FOR THE VIRTUAL RECONSTRUCTION OF ANCIENT STATUES
2021
The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were car…
