The article deals with the description of the methodology for determining the prices of construction work used most often in the reconstruction of historic buildings. The procedure is based on parametric estimating of buildings and on traditional tools and principles of pricing. The historic building is divided into structural parts and technological units. Structural elements are individually valued at the unit price, which was created on the basis of sub-budget. Very strict rules are set for the financing of cultural monuments and the method of valuation is based on the price systems’ methodology. The research also included an analysis of market prices and a subsequent comparison with indicative prices. Proper estimate of historic buildings’ reconstruction cost is also an important input for the decision-making process regarding the actual implementation of the project, its method of execution and its life cycle cost determination.

“…Therefore, the advantages of different sensors are integrated to strengthen the data characteristics. In the 3D digitization field of Tech Heritage (TH), the Gyrolog project (Fritsch et al, 2018;Fritsch et al, 2021) funded by the Federal Ministry of Education and Research of Germany, has innovatively introduced different methodologies, such as Photogrammetry, Computed Tomography (CT) as well as Endoscopy for the 3D digitization of the gyroscopic instrument collection of the University of Stuttgart. The combination of photogrammetry and CT has been discussed frequently in the medical field (Bolandzadeh et al, 2013), however, has not yet been applied often in TH digitization applications (Zhan et al, 2020).…”

Abstract. In this paper we propose a virtual control point based method for the registration of photogrammetry and computed tomography (CT) data. Because of the fundamentally different two data sources, conventional registration methods, such as manual control points registration or 3D local feature-based registration, are not suitable. The registration objective of our application is about 3D reconstructions of gyroscopes, which contain abundant geometric primitives to be fitted in the point clouds. In the first place, photogrammetry and CT scanning are applied, respectively, for 3D reconstructions. Secondly, our workflow implements a segmentation after obtaining the surface point cloud from the complete CT volumetric data. Then geometric primitives are fitted in this point cloud benefitting from the less complex cluster segments. In the next step, intersection operations of the parametrized primitives generates virtual points, which are utilized as control points for the transformation parameters estimation. A random sample consensus (RANSAC) method is applied to find the correspondences of both virtual control point sets using corresponding descriptors and calculates the transformation matrix as an initial alignment for further refining the registration. The workflow is invariant to pose, resolution, completeness and noise within our validation process.

The metaverse has gained popularity recently in many areas including social media, healthcare, education and manufacturing. This work explores the use of the metaverse concept for cultural heritage applications. The motivation is to develop a systematic approach for the construction of a cultural heritage metaverse and to offer, potentially, more effective solutions for tourism guidance, site maintenance, heritage object conservation, etc. We propose a framework for this cultural heritage metaverse with an emphasis on fundamental elements and on characterization of the mapping between the physical and virtual cultural heritage worlds. Efforts are made to analyze the dimensional structures of the cultural heritage metaverse. Specifically, five different dimensions, linearity, planarity, space, time and context, are discussed to better understand this metaverse. The proposed framework and methodology are novel and can be applied to the digitalization of cultural heritage via its metaverse development. This is followed by a detailed case study to illustrate the tangible procedure, constructing a cultural heritage metaverse with a complex and dynamic nature which can be used for different applications, including heritage conservation.
