디지털 헤리티지 관점에서 홀로그래피 기술의 적용과 활용

Hologram is a 3D image technology that can realize a three-dimensional effect and a sense of realism, called a 'screenless display'. If the characteristics of a hologram that allows you to enjoy three-dimensional content and an interactive element that induces audience participation are combined, cultural heritage can be shown in three dimensions from multiple angles, making up for the limitations of existing realistic content. Currently, holography technology is developing, but holograms have not yet been discussed in Digital Heritage. In this paper, we look at how holograms can be applied in the field of digital heritage, and define 'hologram heritage' as a field of digital heritage from the point of view of digital utilization of cultural heritage.

WHAT COMMUNICATION ABOUT HERITAGE CONSERVATION? A CHALLENGE FOR DIGITAL DOCUMENTATION CONTENT

Abstract. The technological methods for digital documentation and the experimental best practice standards used to document and describe the many artistic objects determine the challenges and the numerous uses of today’s cultural heritage.Because of this, it's crucial to preserve heritage by documenting it consciously and using conservation techniques that don't diminish or affect its worth. The study examines the issues we faced in disseminating all of the technical content we have, rather than focusing on the general importance of digital data for the technical staff. To share our heritage, we must make the digital legacy we have built over the last twenty years accessible. Starting from practical examples of dissemination projects in the context of conservation items, the analysis discusses an investigation into the findings and disciplinary culture that have resulted from research conducted by academics in the field of digital heritage on papers, conferences and EU projects produced and conducted between 2018 and 2022. The paper reviews the digital cultural heritage framework outlined by research up to this point.Our findings demonstrate that, despite the fact that the DCH area is constantly changing, we still primarily consider the technical side of digital without considering it as a genuine possibility for openness and sharing.

Finding the Best Lighting Mode for Daguerreotype, Ambrotype, and Tintype Photographs and Their Deterioration on the Cruse Scanner Based on Selected Methods.

In the digital heritage field, the accurate reproduction of hard-to-photograph items, such as daguerreotypes, ambrotypes, and tintypes, is an ongoing challenge. Industrial contactless sensors offer the potential to improve the quality of scanned images, but their capabilities and limitations have not been fully explored. In our research, a dataset of 48 scans was created using the hi-tech industrial contactless sensor CRUSE. Moreover, 3 rare original photographs were scanned in 16 different modes, the most suitable images were determined by specialists in the restoration, and validated through experiments involving eye-tracking, multiple computer vision, and image processing methods. Our study identified the Cruse scanning modes, which can be utilized to achieve the most accurate digital representation of scanned originals. Secondly, we proposed several methods for highlighting the degradation and minor scratches on photographs that otherwise might not be detected by the restorer's naked eye. Our findings belong to four overlapping areas, i.e., image understanding, digital heritage, information visualization, and industrial sensors research. We publish the entire dataset under the CC BY-NC 4.0 license. The CRUSE sensor shows promise as a tool for improving the quality of scanned images of difficult-to-photograph items. Further research is necessary to fully understand its capabilities and limitations in this context.

Reconstruction of 3D digital heritage objects for VR and AR applications

ABSTRACT Constructing the 3D objects based on geometric modelling and graphical techniques is a well-known research activity applied in computer graphics. Techniques to process graphical models are widely used in the field of digital heritage and 3D game. Virtual reality (VR) and Augmented Reality (AR) are technical trends nowadays that can be studied and used in digital high-tech fields like medical training, digital heritage, entertainment industry, digital tourism and museum, etc. In this research, we present a new proposed method for reconstructing the 3D objects of tangible cultural heritages in the virtual environment based on the combination of geometric modelling, computer graphics, VR and AR technologies. The method consists of the following steps: we first collect data of a real object by using a 3D scanner. After processing obtained data, the output is a 3D point cloud. In the next step, we remove noisy data and triangulate the object surface. The novelty point focuses on reconstructing the 3D object by filling the holes. At the end, we build VR and AR applications for visualizing a virtual museum. The contribution of this research leads to open the door for applying in other fields such as 3D Game industry or digital tourism.

A LAYERED-WEB INTERFACE BASED ON HBIM AND 360° PANORAMAS FOR HISTORICAL, MATERIAL AND GEOMETRIC ANALYSIS

Abstract. The latest information technology developments in the field of digital heritage (DH) have enabled the creation of novel virtual experiences favouring information-sharing connected to the 3D digital reconstruction of historical and existing buildings. In recent years, Building Information Modelling for historic buildings (HBIM) projects are the most applied methods to transmit the richness of built heritage from both the geometrical and informative points of view, but they are not always adequate to ensure a simple reading of different type of information for not-expert users. For this reason, further investigations were performed, following a novel SCAN-to-BIM process based on novel Grades of Generation (GOG 9 and 10) in order to digitally represent one of the most complex structure of the Basilica of Sant’Ambrogio in Milan. It is composed of arches supported by pillars, characterised by a double-wave curve, both on its vertical and horizontal axis. The information coming from the previous studies, such as historical documentation, as-found drawings, building archaeology analysis (materials and brick surface texture) and decay data (crack patterns, material discontinuity), was integrated with a novel webimmersive solution able to display 360° pictures, video and HBIM simultaneously. A detailed comparison of the 360 multimedia data of the current arrangement with the one of the HBIM historical phases allow experts and not-experts to analyse the transformation of the arch structures in a new immersive environment with different devices such as laptops, mobile phones and latest virtual and augmented reality (VR-AR) headset.

Digital Heritage Interpretation: Learning from the Realm of Real-World

Heritage interpretation is often used to indicate the storylines adapted to help visitors to engage with and understand historical sites or artefacts. However, until now we hardly find any noteworthy scholarly works, charter, and critical discourse on the theory and methodology of interpretation in the field of Digital Heritage. Praxis limited by such theoretical underpinning, and at the same time the unwitting obsession with technology as a way out for better interpretation is leading most of the digital heritage projects to become descriptive and ocular-centric. Although technologies and tools like game-engines, multi-player virtual environments, haptic devices, augmented visualizations and immersive displays are being used to accentuate experience and visual fidelity, nevertheless, many scholars argue that technology alone can only provide partial interpretation. This paper raises the demands for an interpretive method for digital heritage and proposes some guidelines based on interpretation theories and scholarly materials from the real-world heritage domain.

A SURVEY ON TOPICS, RESEARCHERS AND CULTURES IN THE FIELD OF DIGITAL HERITAGE

Abstract. Digital heritage comprises a broad variety of approaches and topics and involves researchers from multiple disciplines. While the use of digital methods in the text-oriented disciplines dealing with cultural heritage is widely discussed and canonized, an up-to-date investigation on cultural heritage as a scholarly field is currently missing. The extended abstract is about a three-stage investigation on standards, publications, disciplinary cultures as well as scholars in the field of digital heritage, carried out in 2016 and 2017. It includes results of a workshop-based survey involving 44 researchers, 15 qualitative interviews as well as an online survey with nearly 1000 participants. As an overall finding, a community is driven by researchers from European countries and especially Italy with a background in humanities, dealing with topics of data acquisition, data management and visualization. Moreover, conference series are most relevant for a scientific discourse, and especially EU projects set pace as most important research endeavours.
