... In recent years, digital technologies and serious games have widely affected the cultural heritage sector, offering incredible opportunities to enhance the experiential value of heritage assets and improve cultural activities. In this respect, we know that many museums have already used 3D scanning and modelling techniques to create virtual tours of their attractions [1], which could thus also be enjoyed through apps or websites. Not only that but in [14,13] we see how virtual reality can even allow users to interact with museum attractions or reproductions of ancient artefacts through mobile devices. ...
... In the last decades, most of the musealization processes took the advantage of 3D modelling and scanning. In (Alberghina et al., 2017), Morgantina Silver Treasure is acquired and analysed; then, 3D models and analysis results are made available through an ad-hoc web platform. In , the authors conduct a study about Kouros of Lentinoi and propose a web application to make it accessible to the users. ...
Nowadays mineralogical and petrographic sciences represent important resources for the understanding of natural and cultural heritage. Indeed, the implication in economic and social scenario, from the exploitation of geo-resources to the natural stone application in architecture, involves the whole society. In this context, scientific museums are called to enhance society awareness about the importance of minerals and rocks, while facilitating their understanding. It is well-known that the majority of the population is still left out from the museum fruition, usually because of problems of cultural accessibility. In order to find a solution, the Museum of Mineralogy, Petrography and Volcanology of the University of Catania implemented a new communication system based on the visitor’s personal experience. The idea is to give to all users, regardless of their educational level, the possibility to learn by playing. The collaboration among geologists, conservators and computer scientists led to the implementation of a web application called I-PETER: Interactive Platform to Experience Tours and Education on the Rocks. The application, interacting with a database, offers to the public two different modes of exploring the museum’s collections. The visitor can decide to observe the rocks or minerals from the sample exposed to the internal structure and then explore their external application on monuments, or he/she can choose to make a tour in the interactive map, focusing on a particular monument and from there make the virtual reverse path from the macro to the micro scale. Furthermore, thanks to the effort made to construct the knowledge base at the base of I-PETER web app, a labelled dataset of images of rocks and minerals can be easily released for future petrological investigations based on machine learning. Thanks to this pilot project, the museum’s scientific knowledge can promote cultural tourism by making it more accessible to a wide public, as well as support scientific research on petrography and mineralogy.
... The investigation process implemented on physical models is called "Reverse Engineering", while the technique employed is that of "3D Scanning". This non-destructive method is based on the acquisition of the spatial position of points making up the surface of a physical object, then outputting a 3D digital model with a high grade of geometrical fidelity to the starting object (Alberghina M. et al., 2016;Inzerillo L. et al., 2013) (Fig. 11). The specific system employed falls within the "structured light" scanning category (3D Scanner used: Artec Spider), which employs light as a mean of investigation to output a 3D scan of a physical object. ...
We propose here a multidisciplinary approach to the study of a unique historical landmark, currently in a state of great disrepair the “Edicola dell’Averinga”. It was built in 1587 by the Senate of Palermo to protect the Ayn Rutah (Arabic for “Averinga”) spring: from here, the water would then be collected and funnelled towards fertile gardens and dwellings near the city walls. The study of this cryptic artefact was possible thanks to a number of fundamental processes, such as the historical and architectural investigation, the retrieval of documentation both iconographic and archival, the analysis of constructive methodologies and building materials employed, and the application of current surveying and representation systems. It was then possible to propose a series of guidelines for intervention aimed to conciliate the conservation practice with an opportunity for valorisation and promotion.
... The structured light system works with a light source projecting a series of light patterns on the object to be scanned (blue LED). The reflected image is captured by cameras, and from the analysis of the distortion of the pattern, the position is evaluated on each point of the surface to be scanned (Alberghina, et al., 2016). To obtain a complete 3D model, it is sufficient to move around the object and film it from various angles (angular field of view, H × W, 30 × 21 deg). ...
The research focuses on the contribution of the integrated application of Computer Aided Restoration digital procedures as a means to guide the integration measure of an artifact, innovating and implementing the traditional investigation methods. The aim of the study was to provide effective geometrical-formal investigation tools in the frame of the conservation work of Zeus enthroned from Soluntum, conserved in the Archaeological Museum " A. Salinas " of Palermo. The paper describes the workflow of the 3D acquisition and graphical modeling with non-invasive digitalization and high information density techniques to assist the conservation of the legs of the throne, especially the integration of the missing part. Thanks to the technique of the digital fabrication it has been reconstruct the two missing parts following the theoretical criteria as: recognisability, compatibility and retractability. This innovative application of 3D digital technologies have showed as the integrated use of the new technology can be a useful tools for improving the conservation of a work of art.
... In the field of conservation, diagnosis and restoration of Cultural Heritage (CH) (Inzerillo, Dalli Cardillo 2013), several and consolidated procedures have been started by museum institutions, supervisors and specialized agencies that use computerized and automated processes to enhance their traditional research tools. The use of 3D printing systems is now consolidated, specially, in the field of 3D artworks reproduction for exhibitions in museum itineraries or for reconstructions of missing parts, resulting from destruction or damage (Alberghina, et al. 2016;Arbace, et al. 2012). It is known that the traditional approach of producing rubber molds for replication of plaster or resin copies requires a molding procedure on the original work, which is, in fact, an invasive operation that could cause irreversible damage. ...
In In the last years there has been an increasing use of digital techniques for conservation and restoration purposes. Among these, a very dominant rule is played by the use of digital photogrammetry packages (Agisoft Photoscan, 3D Zephir) which allow to obtain in few steps 3D textured models of real objects. Combined with digital documentation technologies digital fabrication technologies can be employed in a variety of ways to assist in heritage documentation, conservation and dissemination. This paper will give to practitioners an overview on the state of the art available technologies and a feasible workflow for optimizing point cloud and polygon mesh datasets for the purpose of fabrication using 3D printing. The goal is to give an important contribute to confer an automation aspect at the whole processing. We tried to individuate a workflow that should be applicable to several types of cases apart from small precautions. In our experimentation we used a DELTA WASP 2040 printer with PLA easyfil.

In recent years, digital technologies and serious game have widely affected the cultural heritage sector, offering incredible opportunities to enhance the experiential value of heritage assets and improve cultural activities. Due to pandemic and the closure of museums the demand for new digital remote solutions for Cultural Heritage has seen a great increase. Thanks to a collaboration between University of Catania, the Museum of Mineralogy, Petrography and Volcanology and a local SME iInformatica S.r.l a serious game for dissemination of mineralogic and petrographic science was developed. The idea behind the project is to give to all the possibility to learn by doing. Through the simulator, users can assume the role of researchers in mineralogy and petrography and, thus, study the minerals constituting the rocks. Within the game a player can learn how to use a petrographic microscope and how to recognise a rock by analysing the single minerals that constitute it and, therefore, to identify the rock itself.KeywordsCultural HeritageMuseumsMineralogyPetrographySerious Game
The research focuses on the digital Computer Assisted Restoration procedures to guide the measure of integration of an artefact, innovating and implementing traditional research methods. Non-invasive 3D Digitalization techniques with high-performance devices allow the generation of applications for high-resolution visualization of three-dimensional environments with the possibility of navigating, analyzing and consulting virtual models in real time. The innovative application of 3D digital technologies has demonstrated that the integrated use of the new technology can be a useful tool to improve the entire process of collecting, storing and consulting information and data related to diagnostic and restoration work. However, even today, in the field of Cultural Heritage conservation, expert restorers are initiating conservation projects, relying exclusively on 2D technical drawing and thematic maps associated with textual legends. Based on these discussions and comparison with colleagues in the field of restoration, it was considered important to define effective support procedures to implement and improve analysis, data interrogation and control of geometry.
