Il Portico meridionale della Cattedrale di Palermo: sperimentazioni di rilievo attraverso l’utilizzo di tecniche Structure from Motion
2014
Structure from Motion (SfM) techniques constitute a very fertile field of investigation within the research of the surveying sector and that of the representation of architecture. They allow us to reach higher levels of reliability and accuracy, both metric and graphical, extremely quickly and with lower costs than other methods, including the laser scanner. In this study, we report the results of some experiments carried out on the southern Portico entrance of the Cathedral of Palermo through the use of the SfM techniques later validated by comparison with the point cloud obtained from laser scanning.
Sperimentazione di una procedura per la creazione di un atlante digitale per la documentazione dei soffitti lignei dipinti di Sicilia
2021
The naves of churches and the halls of noble palaces. The paintings that decorate these ceilings are precious evidence of the wide cultural connections that linked Sicily to Europe and to the Mediterranean area. The paper reports the results of research aiming at the development of a workflow for the creation of a digital atlas of these ceilings. Digital representation overcomes one of the main obstacles to the study, the preservation and the dissemination of these works of art, i.e. the traditional dichotomy between photographic images and drawings. The chosen case study is the ceiling that covers the main hall of the Steri in Palermo, a 14th-century palace that today hosts the offices of …
Lo studio ricostruttivo della Torre Mozza nel castello Carlo V di Lecce: dall'analisi dei dati materiali alla restituzione in 3D
2022
The multi-year research activity, carried out under the direction of the Chair of Medieval Archaeology of the University of Salento, has allowed the realization of this work of digital survey and virtual reconstruction of the so-called Tower Mozza in the castle of Charles V in Lecce
iHERITAGE Project : AR/VR for the enhancement and accessibility of the norman architecture of the Unesco site of Palermo
2023
In the context of conservation and dissemination of cultural heritage, noninvasive technologies for the generation of digital models have produced exponential growth in the quality of the data acquired. The digital contents processed allow the use of architectural contexts that no longer exist or sites that are di cult to access, thanks to the visualisation of high-resolution and immersive products. However, the process from acquisition to visualisation requires optimisation strategies and specific operational choices, depending on the design goals. The study describes some results of a broader research within the iHERITAGE Project funded by the ENI CBC MED Program 2014-2020, critically des…
Atlante di Soknopaiou Nesos: piano di conoscenza e di conservazione digitale
2018
Atlas of Soknopaiou Nesos: project of knowledge and digital preservation. 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 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.
Surveying Ancient Maya Buildings in the Forest
2017
During the last few decades, 3D scanning devices and 3D digital image generating technology has been developed to the point where they significantly reduce errors and time during data collection thus making them highly appropriate tools in the field of archaeology. With regards to surveying, terrestrial laser scanning and digital photogrammetry, they are a viable alternative to traditional methods for measuring. Nevertheless, these technologies are rarely used in projects in the Maya region, even though they offer a wide range of applications, which could be explored and utilised in this subtropical environment. This paper presents the results of digital surveying involving two Maya archaeo…
