High-Resolution 3D Surveying to Support Museum Inclusiveness Strategies

In recent years, there has been a notable increase in attention and efforts directed toward enhancing inclusivity in the dissemination of cultural heritage. This trend is being observed across museums and cultural institutions worldwide, which are actively adopting a variety of innovative strategies to make their collections and assets more accessible to diverse audiences. A wealth of examples has emerged showcasing facilities that have been specifically designed for individuals with disabilities, highlighting a growing commitment to inclusiveness in cultural spaces. In particular, within the context of visual impairment, museums have successfully implemented tactile replicas of artworks and archaeological artifacts. These replicas enable visitors to touch and engage with the physical forms, allowing them to perceive the geometry, texture, and materials of an object in ways that foster greater understanding and appreciation. This study proposes an innovative and forward-thinking approach that leverages high-resolution geomatic surveys, employing structured light projection scanning technology, to reconstruct significant archaeological artifacts digitally. By utilizing these advanced methods, the aim is to provide museums not only with digital models but also with the means to create physical, high-fidelity replicas using cutting-edge 3D printing technologies. This initiative is part of a broader museum inclusivity project being collaboratively executed by the municipalities of Rimini and Riccione in Italy. Through this innovative endeavor, we aim to bridge the gap between cultural heritage and accessibility, ensuring that all visitors, regardless of their physical abilities, can engage with and experience the richness of our shared past in a meaningful and inclusive manner.

3D modelling for the historical reconstruction of an archaeological site: the temple of Iuvanum

This paper proposes an integrated methodology for the 3D reconstruction of ancient structures, based on the geometric analysis of archaeological remains and the use of historical sources. The case study that analysed is the archaeological site of Iuvanum (Italy), with particular focus on the reconstruction of temples, within the Lip3D project - Living forever the Past through a 3Digital world. The approach adopted allowed the development of realistic, historically and architecturally consistent 3D models, contributing to the enhancement and understanding of the site. The integration of geometric survey and historical documentation proved crucial in filling the gaps due to the fragmentary state of the existing structures, offering a plausible reconstruction of a place of great historical significance.

Active Thermography Analysis of Wall Paintings in the Early Christian Basilica Complex of Cimitile (Italy)

This study investigates the use of active thermography (AT) in the mid-wave infrared (MWIR) range to assess the conservation state of wall paintings within the Early Christian basilica complex of Cimitile (Italy). The research focused on paintings in the Basilicas of San Felice and San Giovanni, affected by issues such as pigment loss, detachment, and moisture-related degradation. Controlled thermal stimulation was applied to generate differential thermal maps (DT), enabling the identification of subsurface anomalies, weakened adhesion zones, and potential moisture accumulation. Conducted as a pre-restoration diagnostic survey, the analysis provided essential, non-invasive insights into fragile mural surfaces without physical contact. The results confirmed the diagnostic value of AT in detecting hidden defects and guiding the planning of targeted conservation strategies. This thermographic approach delivers critical data to support preservation efforts of Cimitile’s mural heritage and facilitates the early detection of deterioration processes in comparable historic contexts.

Optical methods for violin diagnostics

Wooden musical instruments are objects that require careful construction and maintenance and are subject to wear. The possibility of having diagnostic techniques available is useful for their restoration. In this work, the use of optical techniques for the diagnostics of an early 1900s violin is tested. In particular, the results obtained with shearography, thermography and 3D scanning will be shown and discussed.

Spectroscopic and Micro-Elemental Analysis of some 20th-Century Paintings: Identifying Diagnostic Pigments

This study addresses the challenges of authenticating early 20th-century paintings, a period marked by the introduction of new artistic materials and techniques. Non-destructive and micro-destructive analytical methods were employed to identify possible forgeries, including Raman Spectroscopy, Diffuse Reflectance Spectroscopy, and SEM-EDX, by analyzing the molecular and elemental composition of artworks. These techniques helped to determine whether the materials used were consistent with those historically available. The results of some investigations highlighted the presence of phthalocyanine pigments, commercially introduced only after the 1930s, casting doubt on the authenticity of the artworks. In contrast, other paintings contained materials typical of the early 20th century, suggesting their authenticity. Overall, the study underscores the importance of an integrated scientific approach in combating art forgery, particularly in modern and contemporary works.

Mineralogical and petrographic analyses of a complex finishing plasters stratigraphy from a 17th century Sardinian Church

The work concerns the study of the original layers of mortar and finishing used in two historical phases of the Church of Madonna d'Itria in Orani (central Sardinia, Italy) which was built in the 17th century. The aim is to analyse the finishing pigmented layers that were superimposed between the 17th and 20th centuries. Furthermore, the study includes the analysis of the mortar substrate on which the pigmented layers were applied, to study their adhesion, mechanical resistance and composition. The general aim of the work is to highlight the techniques and raw materials used for made the finishing plasters and the presence of chemical-physical alteration processes aimed at restoration interventions.

Chemical degradation and mineralogical transformations on based lime blue pigment

The aim of the study is to explain the process of chemical degradation in short times of the ultramarine blue pigment [Na₃Ca(AlSi₃O₁₂)S] when used mixed with lime in a highly basic environment for applications on the outside of stone supports or mortars. For the study, mixtures were produced with only lime and commercial ultramarine blue and also with the red pigment based on ferric oxide (hematite). The mixtures were studied and analysed by optical microscopy and Raman to define the transformations of the original crystalline phases into any new secondary phases.

Multitemporal SAR data for prospection, monitoring and preservation of Cultural Heritage

The present research proposes an interdisciplinary approach that integrates traditional archaeological investigation with advanced satellite remote sensing techniques, through the use of Synthetic Aperture Radar (SAR) data acquired from Sentinel-1 and COSMO-SkyMed missions. The objective is to assess the effectiveness of Earth Observation technologies in preventive archaeology developing a non-invasive methodology for the identification and prospection of buried remains, with the aim of identifying areas of potential archaeological interest for future monitoring activities to ensure the conservation of Cultural Heritage. The study area encompasses the territory of the lower Calore Valley in the Benevento province, with a focus on the site of the Roman city of Telesia Vetere (San Salvatore Telesino), and the Norman bell tower of Telese (Telese Terme). Through multitemporal processing and interferometric analysis of SAR data, the research aims to develop appropriate urban and infrastructural planning, through the creation of potential and risk maps to preserve and promote potential archaeological sites. The proposed model is intended as an operational tool to support public authorities to mitigate the impact of anthropogenic transformations on the historical landscape, while also reducing intervention time and costs. In parallel, the use of interferometric (InSAR and Persistent Scatterer Interferometry) techniques enables the monitoring of the structural condition of above-ground archaeological remains, facilitating the detection of structural instabilities and the activation of preventive measures. The integrated approach thus constitutes a concrete contribution to the advancement of sustainable practices for the protection and enhancement of archaeological heritage.

Structural Investigation through Digital Modelling of Two Domes by Ferdinando Crivelli

Domes were one of the features that made religious buildings grandiose and, with their imposing presence, often defined city skylines. However, before the development of modern construction science, building domes presented a significant challenge to builders, often resulting in numerous designs and revisions that delayed completion by decades, if not centuries. The vulnerability of these structures means they remain one of the most delicate aspects of restoration and consolidation work. For this reason, it is particularly important to understand how they behave. The study of two 19th-century domes designed by Ferdinando Crivelli in Bergamo - the cathedral dome and the church of S. Andrea dome - demonstrates how three-dimensional digital modelling can be used as a valuable preliminary tool in assessing the behaviour of these structures.

Augmented Reality for Knowledge Transfer of Historical Masonry Vaulting Techniques

New technologies and the need to preserve historical heritage are leading to renewed interest in masonry. Despite ongoing efforts in architectural and construction research, the restoration and construction of vaults and domes remain complex, presenting several challenges, including high construction costs, a shortage of skilled labour, and low productivity. Encoding highly efficient historical construction practices, such as the thin-tile vaulting technique (a scaffold-free vaulting method using thin tiles), is crucial for preserving knowledge. Generally, mastering this technique requires years of practical training under the guidance of a master mason. This paper reports the initial findings of a project aimed at evaluating how Augmented Reality can facilitate the transfer of practical knowledge. Through a case study involving the construction of a lowered vault, the impact of adopting Augmented Reality on accuracy was assessed.
