Cultural Heritage is recognized as a priceless asset of human being, which exposes the humanity's achievements over centuries. The need for documentation and preservation of cultural heritage is well known worldwide. Digital surveying techniques are playing a catalytic role towards recording and documentation of cultural heritage. This chapter describes the methodological and technological aspects of image-based recording and documentation approaches acting as the vehicle for the digital surveying of cultural heritage. The chapter not only describes the different technologies and techniques used but also goes to the extent of clarifying several applied implementation issues. Three different examples and application case studies from a small, a medium and a large-scale cultural heritage objects are provided to demonstrate the developments.

Recently, we proposed stochastic point-based rendering, which enables precise and interactive-speed transparent rendering of large-scale laser-scanned point clouds. This transparent visualization method does not suffer from rendering artifact and realizes correct depth feel in the created 3D image.In this paper, we apply the method to several kinds of large-scale laser-scanned point clouds of cultural heritage objects and prove its wide applicability.In addition, we prove better image quality is realized by properly eliminating points to realize better distributional uniformity of points. Here, the distributional uniformity means uniformity of inter-point distances between nearest-neighbor points.We also demonstrate that highlighting feature regions, especially edges, in the transparent visualization helps us understand 3D internal structures of complex laser-scanned objects. The feature regions are highlighted by properly increasing local opacity of the regions.

Cultural Heritage Objects

Cultural heritage professionals are becoming increasingly concerned about the lack of care being taken by municipalities for their cultural heritage objects which include works of art in public places. They have therefore begun to ask the public to help take care of “their” cultural heritage through so-called public participation projects. Cultural heritage professionals tacitly assume that if they “teach” the public to treasure such objects of “their” heritage, the public will become more proactive in helping to conserve them. However, research being conducted by the authors is showing that a majority of the general public often has a completely different awareness and/or feeling about cultural heritage objects in their neighborhoods than the cultural heritage professionals think they have, or think they should have. Three recent case studies carried out by the authors show that these differences are most noticeable during so-called “value moments” at the beginning and at the perceived end of an object’s life. These are the two moments when decisions are made, usually by cultural heritage professionals, to place an object in a neighborhood or have it significantly changed or removed, often to the surprise and disagreement of the residents. Between these two moments lay many moments when an object is taken for granted, grudgingly accepted, or not even noticed. Given the fact that cultural heritage professionals often make the ultimate decisions and do not always consider or outright ignore public opinion, it should not be surprising that there is an increasingly negative public perception of what they do. The results of the case studies illustrate the need for professionals to consider and accept as valid, public feelings about cultural heritage objects in their neighborhoods.

Learning can be done by anyone and anywhere. Cultural heritage provides an alternative interestinglearning resource. It is just that not many people understand the benefts that can be obtained fromcultural heritage. Tis Community Service by FIB UGM in 2018 made an effort so that peoplewould be more familiar with learning resources from cultural heritage objects. Te objects used inthis study are reliefs which depict a music group from the Borobudur Temple. Tis choice is basedon Gardner's theory which states that every human being has a different intelligence. Among thenine intelligences presented by Gardner, musical intelligence is one of them. By applying Gardner'stheory, especially musical intelligence, the introduction of objects of relief about people playing musicfrom Borobudur reliefs to people who like music is expected to be able to facilitate them to capturethe message conveyed.Reliefs about people playing music from Borobudur Temple is introduced to a group of musicians,namely the Pesantian Wisnu Sakti Tambakan group located in Tambakan Village, JogonalanDistrict, Klaten Regency. Te way to do this is to look at and imitate body movements such as thosedepicted on the reliefs of musicians playing musical instruments at Borobudur Temple. Te resultof the observations show that the participants feel the beauty of the movements and feel the sound ofthe music produced with the position of the hands and the appropriate instruments so as to producebeautiful and unique sounds. From the process of the activities carried out, this group was able toproduce several pieces of music. Te music produced also make the participants feel happy and planto use the results of this learning for various activities.

We propose a method for the precise 3D see-through imaging, or transparent visualization, of the large-scale and complex point clouds acquired via the laser scanning of 3D cultural heritage objects. Our method is based on a stochastic algorithm and directly uses the 3D points, which are acquired using a laser scanner, as the rendering primitives. This method achieves the correct depth feel without requiring depth sorting of the rendering primitives along the line of sight. Eliminating this need allows us to avoid long computation times when creating natural and precise 3D see-through views of laser-scanned cultural heritage objects. The opacity of each laser-scanned object is also flexibly controllable. For a laser-scanned point cloud consisting of more than 10<sup>7</sup> or 10<sup>8</sup> 3D points, the pre-processing requires only a few minutes, and the rendering can be executed at interactive frame rates. Our method enables the creation of cumulative 3D see-through images of time-series laser-scanned data. It also offers the possibility of fused visualization for observing a laser-scanned object behind a transparent high-quality photographic image placed in the 3D scene. We demonstrate the effectiveness of our method by applying it to festival floats of high cultural value. These festival floats have complex outer and inner 3D structures and are suitable for see-through imaging.

In the article the results of research works of a large-scale object of cultural heritage of the Earth mound of the Krasnoyarsk fortress with application of aerial photography from the unmanned aerial vehicle are presented. The Krasnoyarsk fortress is a unique monument of military fortifi cation architecture of Russia of the fi rst half of the XVIII century and one of the largest defensive lines in Russia, created for protection of the southeastern edge of the European Russia against att acks of nomads. The results of vertical and oblique aerial photography allow to reveal the general architectural and planning composition of the Earth mound of fortress as well as to see all the area of a complex and to defi ne the territorial unity with other fortifi cation constructions. The methods of use of unmanned aerial vehicles give materials about the object in study and allow to bind its spatial location to the coordinate system of the terrain, to create three-dimensional model of the area, to compare the received images with the available historical cards and plans, which will signifi cantly facilitate the task of registering the Fortress with the security authorities and withdrawing its territory from economic use.

The purpose of the research work is to analyze the norms of Federal laws, as well as the laws of the Russian Federation's constituent entities, devoted to the definitions and classification of the concepts “cultural heritage”, “historical and cultural monuments”, “cultural values”. Conclusions obtained in the course of the research: based on the study of current legislation, it is concluded that the definitions of “cultural values”, “cultural property”, “objects of cultural inheritance” contained in various normative legal acts differ in content. Based on the research, the author proposes the concept of “cultural values”.
