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…
Soknopaiou Nesos project 2019. Il survey 3D e il survey ceramologico
2020
In 2019, in the framework of the Soknopaiou Nesos Project (University of the Salento, Lecce, Italy), two research teams began a multidisciplinary survey atDime es-Seba. One team conducted a 3D survey with a view to generating a digital model of the entire site using Camera Scanner-based techniques while the other undertook a survey in order to obtain knowledge of the spatial and chronological development of the settlement. The survey aims to create a Topographical Atlas which will support the acquisition of evidence for addressing specific archaeological problems concerning the city. The project will also contribute to the protection, conservation and monitoring of the site.

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…
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 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…
GEOMATIC METHODOLOGIES FOR THE STUDY OF TEATRO MASSIMO IN PALERMO (ITALY)
2017
Abstract. This work illustrates the use of geomatics techniques for the documentation of Teatro Massimo in Palermo (Italy), one of the most important and big in Italy and in Europe. The theatre is characterized by a very complex structure and is realized also using innovative solution, studied at the time of the project specifically for this building; for example, an original system was realized for a natural air-conditioning system of the auditorium. Due to his complexity, the documentation of the Teatro Massimo requires studying specific survey solutions for the different parts of the building. In this paper, some studies on two of the most representative parts of the building were descri…
THE INTEGRATED 3D SURVEY for UNDERGROUND ARCHAEOLOGICAL ENVIRONMENT
2019
Abstract. The task of documentation and conservation of Cultural Heritage defines the challenges that geomatics techniques have to overtake in order to provide different solutions that combine the automation of processes with accurate results. The employment of integrated technologies allows improving the documentation of Cultural Heritage from a quantitative and qualitative point of view. The use of range and image-based techniques ensures the possibility to completely record articulated structures such as building with underground environments. The latter present often problematic survey conditions that imposed well planned and appropriate solutions. In this context, the paper presents th…
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…
