Abstract. In recent years, there has been a trend towards synergies among cultural heritage institutions, such as GLAM (Galleries, Libraries, Archives & Museums) collaborations in the field of information resource management. These institutions have been actively promoting the construction of digital humanities projects. Such projects primarily target data resource construction and digital humanities services, which are in line with the service functions of GLAM institutions. With the development of networking and digitisation, museums have been making more prominent contributions to knowledge sharing and dissemination.Digital technology has brought about profound changes in the academic research environment. The expansion of traditional research and the emergence of new questions in the digital environment have promoted novel perspectives, thinking, and methods. With the increase in digitisation of cultural heritage, the scale of data has grown rapidly, and the types of data available have been continuously enriched, from knowledge aggregation to knowledge organization and even knowledge transmission. Therefore, it is necessary to examine the tools of digital humanities, which constitute an important means of knowledge production, and to work with traditional GLAM institutions to promote digital thinking and interdisciplinary knowledge integration methods. At the technical level, methods such as knowledge graphs and ontologies are used to construct a multi-layered and systematic knowledge system. This paper presents a review focused on three cultural heritage models, CIDOC CRM, Europeana and the Sampo Model, and reflects on three aspects of the current models: technical framework construction, digital resources, and service systems.
Understanding the issues in cultural heritage preservation and digital heritage begins with knowledge exchange and the education of present and future stakeholders in the sector. Therefore, an innovative integration of digital technologies into museum practice and professional development courses is of great importance. In this article we describe three case studies involving knowledge exchange between universities and cultural heritage institutions. All three projects involved interdisciplinary expertise and the use of novel digital technologies which allow the recording of highly accurate 3D data for the purposes of archiving, research, preservation and public engagement. The first case study is a collaboration between The Postal Museum, the London Museum Group and UCL's Civil, Environmental and Geomatic Engineering (CEGE) department, which delivered a feasibility study as to the use of 3D technologies for the documentation of metal objects. The second is a project involving UCL CEGE, UCL Digital Humanities and The Wellcome Trust in London, consisting of a training workshop, the development of a new low cost 3D imaging kit and outreach activities. The final study, initiated by the German Maritime Museum together with the Jade University of Applied Science in Oldenburg, is developing a 3D acquisition protocol for monitoring the Bremen Cog, a 14th century ship. Concluding the article are reflections on the lessons learnt and recommendations for fostering capacity building and knowledge exchange. Further conclusions are drawn on the importance of introducing museum and heritage professionals to the latest developments in digital technologies, with examples of learning opportunities in workshops or academic curricula.
ABSTRACT:Polished metallic surfaces exhibit a high degree of specularity, which makes them difficult to reproduce accurately. We have applied two different techniques for modelling a heritage object known as the Islamic handbag. Photogrammetric multi-view stereo enabled a dense point cloud to be extracted from a set of photographs with calibration targets, and a geometrically accurate 3D model produced. A new method based on photometric stereo from a set of images taken in an illumination dome enabled surface normals to be generated for each face of the object and its appearance to be rendered, to a high degree of visual realism, when illuminated by one or more light sources from any angles. The specularity of the reflection from the metal surface was modelled by a modified Lorentzian function.
A new master's degree commenced in 2017 at the University of Bamberg. The purpose of the M.Sc. Digital Technologies in Heritage Conservation is to impart theoretical and practical knowledge and develop competence in critical assessment and object-oriented solutions. The aims, curriculum and methods of teaching will be discussed in this paper.
