It is a structure that represents one of the oldest and best preserved thermal buildings with retrograde path in Sicily. Taking into account the typological, structural and decorative peculiarities that characterize the site, it was necessary to operate through integrated digital survey methods (laser scanning and SFM), obtaining a 3D model which describes the building in its entirety. The thermal building was inserted in the first century AD in a residential block dating back to the Hellenistic period. It is located in the South-Eastern part of the orthogonal area that marks the urban area and is bounded by two major east-west arterial roads (decumani), intersected perpendicularly by narrow streets (cardines) in the South-North direction. The thermal baths are located on the south terrace of insula IV and are composed of a central body with a peristyle overlooked by two exedras, while the aligned rooms, where you can see different phases of construction and decoration, consist of: an apodyterium, a frigidarium with a basin, a tepidarium, a destrictariume and, finally, a calidarium. The geometric and formal characteristics of the surveyed spaces have led to the choice of topographic surveying techniques such as 3D Laser Scanning and the reconstruction of high quality textured meshes through SFM techniques to document floor mosaics and walls features. The digital model obtained has allowed for a better understanding of the archaeological complex and has provided a digital document useful for the graphic representation of the site (plan, elevations, sections and orthophotos) and for further multidisciplinary investigations aimed at the conservation of the asset and its enhancement

The article focuses on two digital survey campaigns carried out respectively in 2014, laser scanning, and 2019, Structure from Motion. Starting from the point cloud by laser scanner, the most recent, low cost and user-friendly photogrammetric tools (GoPro camera and software Agisoft Metashape) have been used during the 2019 campaign in order to update and to improve the previous dataset, which was used as a grid for georeferencing and scaling the new virtual model. Special attention was addressed to the comparison of the two datasets and to the reuse of the first one for georeferencing and scaling the second one. Furthermore, the research has been focused on the opportunity to exploit the obtained virtual model both for scientific purposes and f...

The aim of the research was to experiment and verify a single process of digital acquisition, elaboration and communication, and to investigate the potential of shifting from 3D to 2D for the creation of metrically and geometrically reliable orthophotos (so called new photogrammetry). In particular, this kind of application has not been widely used by the archaeological teams working in Sicily, especially when the Computer Vision is not aimed at the reconstruction or the dissemination of the results. The site of Calicantone represented an ideal context for a multiple experimentation of image-based modelling. Indeed, the construction of a methodolo...

The studied balustrade adorns and protects the steps of Villa Cerami garden, which is a suggestive example of 18th century ‘urban villa’, located in the very core of the Baroque Catania. Sadly, these stunning steps, whose magnificence and placement characterises the out-door environment of the building, at present suffer from bad degradation conditions, and the decorative details adorning the baluster are affected by irreversible damage. The causes of this ongoing degradation process are: material features, humidity, pollution and the consumption caused by the activities performed in the building. Since 1957 it has been the location of the Faculty of Law of the University of Catania. In this study, three balusters affected by the main weathering forms (biological colonization, black cr...

This chapter focuses on the use of new technologies aimed at the documentation and communication of Knowledge, with the objective of involving the community through a participatory and immersive approach. Technologies, visualization, and fruition are, therefore, the key terms of the work in progress conducted by a team from the University of Catania and aimed at the documentation, safeguard, and communication of the ecclesiastical architectural heritage of Acireale, built after the earthquake of 1693.

The aim is to find common (invariant) and uncommon (variant) features in terms of identification of architectural parts and their relationships, geometrical rules, dimensions and proportions, construction materials and measure units, in order to model archetypal shapes from which it is possible to derive all the style variations. At this regard, a set of 14<sup>th</sup> - 16<sup>th</sup> century gothic portals of the catalan-aragonese architecture in Etnean area of Eastern Sicily has been studied and used to assess the feasibility of the identified workflow.<br><br> This approach tries ...
