Ontological Entities for Planning and Describing Cultural Heritage 3D Models Creation
ArXiv, 2021
In the last decades the rapid development of technologies and methodologies in the eld of digitization and 3D modelling has led to an increasing proliferation of 3D technologies in the Cultural Heritage domain. Despite the great potential of 3D digital heritage, the "special eects" of 3D may often overwhelm its importance in research. Projects and consortia of scholars have tried to put order in the dierent elds of application of these technologies, providing guidelines and proposing workows. The use of computer graphics as an eective methodology for CH research and communication highlighted the need of transparent provenance data to properly document digital assets and understand the degree of scientic quality and reliability of their outcomes. The building and release of provenance knowledge, consisting in the complete formal documentation of each phase of the process, is therefore of fundamental importance to ensure its repeatability and to guarantee the integration and...
VIRTUAL ARCHAEOLOGY (Methods and benefits), 2015
The paper presents the challenges in the research field of computer based 3D reconstruction of lost and/or not realized art and architecture. The increasing amount of 3D documentation and 3D reconstruction projects (3D data sets) on the one hand, and still not solved problems of e-documentation and long-term preservation of the knowledge „within and around“ the 3D models on the other hand request enforced efforts in the interdisciplinary field of Spatial Humanities and Virtual Archeology. The presentation brings insight into a complex discipline and introduces new approaches in data acquisition, geometry modeling, semantic data modeling (domain ontology), preservation (RDF-Triple-Store) and visualization (WebGL-Technology) of the knowledge models.
Embedding Knowledge in 3D Data Frameworks in Cultural Heritage
At present, where 3D modeling and visualisation in cultural heritage are concerned, an object’s documentation lacks its interconnected memory provided by multidisciplinary examination and linked data. As the layers of paint, wood, and brick recount a structure’s physical properties, the intangible, such as the forms of worship through song, dance, burning incense, and oral traditions, contributes to the greater story of its cultural heritage import. Furthermore, as an object or structure evolves through time, external political, religious, or environmental forces can affect it as well. As tangible and intangible entities associated with the structure transform, its narrative becomes dynamic and difficult to easily record. The Initial Training Network for Digital Cultural Heritage (ITN-DCH), a Marie Curie Actions project under the EU 7th Framework Programme, seeks to challenge this complexity by developing a novel methodology capable of offering such a holistic framework. With the integration of digitisation, conservation, linked data, and retrieval systems for DCH, the nature of investigation and dissemination will be augmented significantly. Examples of utilisating and evaluating this framework will range from a UNESCO World Heritage site, the Byzantine church of Panagia Forviotissa Asinou in the Troodos Mountains of Cyprus, to various religious icons and a monument located at the Monastery of Saint Neophytos. The application of this effort to the Asinou church, representing the first case study of the ITN-DCH project, is used as a template example in order to assess the technical challenges involved in the creation of such a framework.
Culto: An Ontology-Based Annotation Tool for Data Curation in Cultural Heritage
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
This paper proposes CulTO, a software tool relying on a computational ontology for Cultural Heritage domain modelling, with a specific focus on religious historical buildings, for supporting cultural heritage experts in their investigations. It is specifically thought to support annotation, automatic indexing, classification and curation of photographic data and text documents of historical buildings. CULTO also serves as a useful tool for Historical Building Information Modeling (H-BIM) by enabling semantic 3D data modeling and further enrichment with non-geometrical information of historical buildings through the inclusion of new concepts about historical documents, images, decay or deformation evidence as well as decorative elements into BIM platforms. CulTO is the result of a joint research effort between the Laboratory of Surveying and Architectural Photogrammetry "Luigi Andreozzi" and the PeRCeiVe Lab (Pattern Recognition and Computer Vision Lab) of the University of Catania, * Corresponding author. This is useful to know for communication with the appropriate person in cases with more than one author.
An ontology for 3D cultural objects
… Symposium on Virtual Reality, Archaeology …, 2006
3D cultural objects are digital 3D replicas of objects having a cultural value, as models of artefacts, reconstructions of buildings, sites and landscapes. As such, they have a twofold nature, and inherit properties both from their digital nature, like the shape and texture, and from the cultural content, for instance to be used for scholarly purposes or communication to the public. In some cases, one of the natures prevails on the other. This may be the case because the object is being processed, e.g. visualized on a computer, or scrutinized by heritage scholars for review. In a few others, it is unfortunately the user's narrow-minded attitude that leads to take into account only one nature of such an object and neglect the other. It is therefore necessary to explore a way of documenting 3D cultural objects that keeps together all the relevant information, both the cultural and the digital one. In this paper we propose an ontology for such complex objects that owns the following important properties: i) it is sufficiently general to encompass very different artefacts, from pottery sherds to historical landscapes; ii) it fully complies with international standards for heritage, in this case CIDOC-CRM, of which it can be shown to be a specialization/extension; iii) it is sufficiently simple to be used and understood by heritage practitioners and professionals with moderate computer skills, and documents items in a plain, human readable and understandable way; iv) items documented as instances of this ontology can be efficiently processed for the most frequent purposes, as computer visualization, retrieval of cultural information or storage in a database; v) it is ready for compliance with other important requirements, as for instance the proposed charter on credibility known as London Charter.
Semantically rich 3D documentation for the preservation of tangible heritage
2012
Traditionally, 3D acquisition technologies have been used to record heritage artefacts and to support specific tasks such as conservation or provenance verification. These exercises are usually a one-off as the technology and resources required are cost intensive. However, there is a recent impetus on the creation of 3D collections to document heritage artefacts which are semantically enriched by using annotations. A requirement of these solutions is the ability to support several representations of a heritage artefact recorded through time. This paper will propose an infrastructure to systematically enrich 3D shapes in a collection by using propagated annotations. In addition, it will describe the mechanisms for annotating, propagating and structuring the annotations using the CIDOC-CRM ontology. The results of this research have the potential to support heritage organisations in making their semantically rich 3D content available to a wider audience of professionals.
3D Documentation and Semantic Aware Representation of Cultural Heritage: the INCEPTION Project
2016
As part of 3D integrated survey applied to Cultural Heritage, digital documentation is gradually emerging as effective support of many different information in addition to the shape, morphology and dimensional data. The implementation of data collection processes and the development of semantically enriched 3D models is an effective way to enhance the dialogue between ICT technologies, different Cultural Heritage experts, users and different disciplines, both social and technical. The possibility to achieve interoperable models able to enrich the interdisciplinary knowledge of European cultural identity is one of the main outcome of the European Project "INCEPTION - Inclusive Cultural Heritage in Europe through 3D semantic modelling", funded by EC within the Programme Horizon 2020. The project ranges from the documentation and diagnostic strategies for heritage protection, management and enhancement, to the 3D acquisition technologies. The development of hardware, software...
Virtual heritage system: modeling, database & presentation
2001
This paper addresses three research issues for virtual heritage system, 3D modeling, 3D media asset database management, and interactive presentation through networks. We first show an overview of our virtual heritage system. Then, our approaches on each research issue are introduced. We develop 3D modeling environment using both of two emerging techniques, i.e., image-based 3D modeling and 3D laser scanning-based 3D modeling techniques. Each technique captures range data of 3D objects using 3D input devices and uses 3D mesh modeling scheme. Our test results from both of these trials are shown. One of the important tasks for virtual heritage system is how to manage the various kinds of cultural heritage assets. For this goal, our approach for an asset management is descibed, which includes the system configuration and asset creation method. Finally, we address how to present virtual heritages. Here, we show two approaches, web-based and virtual reality theater-based system. We also address the networking issues for transcontinental cutural heritage exchange and our future plan for 3D cyber museum through Trans-Eurasia Information Network.
