Cultural Heritage Objects

Preservation of cultural heritage is associated with their fixation by performing measurements. They are very effective when we use the terrestrial laser scanning method, as a means of obtaining the most complete and reliable information on the geometry of the object at a particular time. However, the method of laser scanning is not so widely represented in the technical literature, for instance, on Totalstation- or theodolite surveys due to the relatively recent introduction in geodetic practice, especially for the purposes of fixing monuments. There are many questions on application of this technology for the above mentioned aim, they focus on ensuring the required regulatory or its accuracy. The authors discuss a geodetic method for ensuring the precision of laser scanning surveys including the design and estimating the fixed control points’ exactness, as well as the tie ones. The influence of angular and linear measurements over the laser positioning accuracy is shown. The technique is demonstrated, including modeling design schemes and their comparison with actual data. The research results are confined to the world-class cultural heritage site of Baalbek temple complex in Lebanon.

The three main methods of digitization can be broadly defined as contact digitization, image-based digitization (photogrammetry), and geometry-based digitization (laser scanning). With the development of the latter two digitization methods, and advanced rendering technologies, virtual displays and museums can now be used widely. (Hung, 2007) Furthermore, recent developments in interactive 3-D computer graphics technology have seen an increased interest in, and use of, 3-D digitization for cultural heritage objects. (Muller-Wittig, Zhu, & Voss, 2007) Technologies for reconstructing or remodeling physical components in 3- D formats are not new in the engineering field, in particular within manufacturing engineering. However, 3-D digitization used for the preservation and archiving of cultural artifacts is relatively recent.

Cultural Heritage Preservation

Abstract. Cultural heritage preservation via 3D digitization is becoming more and more important. Besides conventional buildings and landmarks, many technical instruments and artifacts, which belong to tech heritage (TH), are also of great importance, historically and didactically. Gyroscopes, which can be dated back for 200 years, are fascinating instruments with complex structures and different working principles. With such properties, any 3D digitization of Gyroscopes could not be realized by simply using conventional solutions of photogrammetry or laser scanning. In our work, we introduce photogrammetry, endoscopy and computed tomography (CT) for an integrated 3D digitization solution. Though photogrammetry has been widely used for the purpose of cultural heritage preservation, 3D reconstructions using the other two sensor systems have their own challenges. For an endoscope, a pre-calibration solution has been put forward and the Structure-from-Motion (SfM) process has been optimized to deal with the drift caused by a long imaging trajectory. Regarding the CT 3D reconstruction, we mainly focus on the 3D representation’s completeness and the denoising process. In the section of data integration, we designed different methods according to the characteristics of the objects as well as the 3D models from different sonsors. In case of limited overlap between the pair of point clouds, the Gauss-Helmert model with manually picked control points is applied for the estimation of the transformation matrix. CT point clouds, which hold only the intensity values representing the material attenuation, could be integrated with photogrammetry data via a surface color mapping method using the photogrammetric images or the primitive based corresponding virtual control points. Through our research, the concept of integrating photogrammetry, endoscopy and CT for 3D digitization of Gyroscopes is validated. Furthermore, advantages and disadvantages involved in the complete process are discussed and a solid foundation has been laid for further research.

The aim of this article is to present the influence of detector selection for the image-based Terrestrial Laser Scanning (TLS) registration method. The presented results are the extended continuation of investigations presented in the article, ‘The Influence of the Cartographic Transformation of TLS Data on the Quality of the Automatic Registration’. In order to obtain the correct results of the TLS registration process, it is necessary to detect and match the correct tie points, which are evenly distributed across the entire area. Commonly, for TLS data registration manually or semi-manually corresponding points are detected. However, when large, complicated cultural heritage objects are investigated, it is sometimes impossible to place marked control points. The only possibility of resolving this problem is the use of image-based TLS data registration. One of the most important factors that influences the quality and ability to use it correctly, is accurate selection. For this purpose, the authors decided to test three blob detectors ASIFT, SURF, CenSurE, and two point detectors FAST and BRISK. The results indicated that selection depends on two factors: if the time required for data processing is not important, the ASIFT algorithm should be used, which allows for full registration, but if not, a combination of other algorithms with results supervision should be considered.

The process of transformation of communicative practices of interpretation and popularization of cultural heritage in the framework of the accelerating dissemination and integration of digital technologies in all spheres of human activity is considered. The rhizomorphism of modern digital culture is analyzed, which inevitably aff ects the nature of the representation of monuments in virtual space. It is hypothesized that, despite the variety of approaches presented for creating digital avatars of cultural institutions and cultural heritage objects in a virtual environment, none of the currently existing solutions for Saint-Petersburg makes it possible to represent a cultural heritage object in the context of its retrospective visualization and connection with other culturally signifi cant objects, such as events and personalities. Conceptual grounds are proposed for a deeper understanding of the cultural monument as a subject of representation. An attempt is made to comprehend the representative capabilities of digital instruments, moreover, the question of the need to develop a full-scale and multi-functional digital platform for representing cultural heritage sites is raised.

Tourism proved to contribute to the acceptance of local revenues and plays a role in alleviating poverty. Tourism also plays a role in efforts to improve the nation's identity and encourage awareness and community pride of the natural and cultural wealth. With tourism, a country or more specifically of local government where it is located will get revenue from the income of each tourism destination. Potential tourism attraction in Sangiran, Sragen has not been fully optimally managed, so that the existence of a tourism asset has not received the maximum response from visitors in the form of tourist visits.The problem in this research is how the potential of cultural tourism Sangiran site and what strategies are applied to the future development of Sangiran Site as a tour. This research aims to find the strategies in Sangiran tourism development according to the character as a world heritage site. This research uses SWOT analysis, to find strengths weaknesses factors, opportunities and challenges faced in the development of these attractions. This research is qualitative which look at research as a process, in order to gain a deep understanding with regard to community interaction in the area of research, Sangiran Site, Kalijambe, Sragen, Central Java Province.The results show that as rated the world's cultural heritage, tourism development positions Sangiran located in a strategic position if it is able to use optimally the power and opportunities that it has. One strength of tourist objects is because of the uniqueness and rarity, as shown by a collection of objects on display in the Museum of Ancient Man Sangiran. The cultural heritage objects, dating from prehistoric times, either in the form of early human fossils millions of years old, as well as other antique objects which the old is hundreds of years old is very important to understand the life of the ancestors of Indonesia in the past.Efforts to prevent the theft of Sangiran Site’s fossils, so in addition to the ongoing elucidation of the importance of cultural heritage, legal sanctions should be enforced, due to the exploitation of fossil violating Republic Act No. 11 the Year 2010 About the Cultural Heritage. Therefore, it is considered important and urgent, in order to be formed Awareness group as one component in society which have an important role and contribution in the development tourism of the Sangiran Site.

Strong cultural heritage management relies on a thorough evaluation of the threats faced by heritage sites, both in the present and in the future. In this study, we analysed the changes in the position of Hiorthhamn shoreline (Svalbard), which is affecting coastal cultural heritage sites, for a period of 93 years (1927–2020). Shoreline changes were mapped by using maps, ortophotos, drone images, terrestrial laser scanning (TLS), and topographic surveys. Also, TLS was used to 3D document the endangered coastal cultural heritage sites. Detailed sedimentological and morphological mapping was made in the field and from the newly acquired drone images in order to understand shoreline-landscape interaction and to depict changes occurring from 2019 to 2020. Short-term (2019–2020) and long-term (1927–2020) shoreline erosion/accretion was made with the help of the Digital Shoreline Analysis System (DSAS) and prompted a subdivision of three sectors, based on change pattern. Compared to a previous long-term analysis (1927–2019), this year’s average erosion rate analysis (expressed by the EPR parameter) for the 93-year period is −0.14 m/yr. This shift in mean development is due to a newly formed spit-bar in Sector 2. Referring strictly to Sector 1, where the protected cultural heritage objects are located, the erosion rate increased from the previous analysis of –0.76 m/yr to −0.77 m/yr. The shoreline forecast analysis highlights that half of the protected cultural heritage objects will likely disappear over the next decade and almost all the cultural heritage objects analysed in this study will disappear in roughly two decades. This shows the great danger the Arctic’s cultural heritage sites is in if no mitigation measures are undertaken by the local authorities.
