In this paper, the authors briefly review the state of the art of the 3D acquisition and digitizing techniques applied to heritage. The main focus is on motivations, issues and technical specification of the 3D digitizing of heritage artworks. Different digitizing technologies currently available for this specific application have been evaluated and tested, with application to a pair of case studies, showing that 3D digitizing technologies are sufficiently developed for extensive application in the field of cultural heritage. 相似文献

In the last few years the improved performances of graphics hardware and the growing availability of broadband internet connections have eventually led to effectively adding a third dimension to web interfaces, achieving what is commonly referred to as Web3D. Nevertheless, these technologies are not yet widespread, especially in the cultural sector, for at least two factors: technological limitations, mostly in the lack of coherent and effective metaphors to visualize and interact with digital cultural assets using the third-dimension as an added value rather than as a stylish gadget, and communication issues, as, despite the principles stated in the London Charter aimed at ensuring technical and intellectual rigor for the digital visualization of cultural heritage, a proper way to deal with relevant and sustainable 3D information is not yet completely established. For this reason this paper focuses on identifying and analyzing the aspects that may contribute to a more efficient use of Web3D technologies to access cultural content, in order to set up a set of development standards aiming to encourage web-based learning and guaranteeing systems accessible and usable by the widest possible audience. 相似文献

Precise documentation of cultural heritage status is essential for its protection and scientific studies carried out during the restoration and renovation process. The close range photogrammetry has been used successfully for documentation of cultural heritage. With recent developments in computer and information technologies, this well-known traditional method has been replaced with digital close-range photogrammetry. This new method offers us new opportunities such as automatic orientation and measurement procedures, generation of 3D vector data, digital ortho-image and digital surface model. Terrestrial laser scanning is another technology that in recent years has become increasingly popular for documentation which provides very dense 3D points on an object surface with high accuracy. In addition, the 3D model and digital ortho-image can be easily generated using generated 3D point cloud and recorded digital images. 相似文献

Historic buildings are of great cultural, research and aesthetic value, and they can reveal past events and developments. Tianjin, an ancient city originated from Yuan dynasty, is famous for its Group-living Yards. Derived from settlements in foreign concession districts, these Yards exhibit different building styles and are now an integral part of Tianjin's cultural heritage. However, many of these buildings disappeared due to the ravages of frequent fire disasters. To protect Group-living Yards and to alleviate fire losses, fire hazard survey was conducted. Then corresponding control and mitigation methods were proposed. Yuan Residence, one of the typical Group-living Yards, was employed as an example to demonstrate the availability of the methods proposed by using fire dynamics simulator. Finally, comprehensive suggestions and disaster mitigation methods were given for Group-living Yards in Tianjin, which gives guidance on developing policies and procedures for incorporating fire prevention and protection features into these buildings. 相似文献

Roads built by civil or military engineers from the 18th century onwards form an essential part of our heritage, but currently considered on a very infrequent basis. They represent one of the main turning points in the development of the transport system and serve to gain a better understanding of the historic construction of many landscapes and their current arrangement and operation. Their consideration as heritage has to be made on a territorial scale. This approach regards landscape as a cultural artifact, which is undergoing constant design, construction and transformation, where the road is considered as an axis that shapes the landscape and that contains individual elements such as associated structures or buildings. One of the most important characteristics of historic roads undoubtedly lies in the fact that they are a heritage that is still in use. Many of the roads built for carriages or the first automobiles have, in fact, served to trace the current network of roads and motorways. For this reason, many historic routes have undergone considerable modification and a large percentage of their heritage has disappeared. Likewise, their original or more intact sections, that is to say those that were replaced during their gradual adaptation to the automobile in the 20th century, are not always easy to identify. The distinction and undoubted documental value of historic roads, together with the neglect and vulnerability of these assets, makes it essential to define specific strategies with some degree of urgency in order to appraise this heritage. In this respect, the purpose of this article is to establish a methodology with which to identify sections of historic roads that were replaced by new alignments. The decision to focus the work on these sections is based on the fact that the infrastructure of these and particularly the older sections, have undergone a smaller degree of change and subsequently retain their original routing and geometry and a far higher number and variety of heritage elements more intact. This has made it possible to ascertain the diversity of elements composing the heritage of historic roads and enables the classification of the same. The identification methodology has been applied to a significant proportion of the Spanish main road network on selecting some 15 sections of historic roads of very different characteristics. Files have been prepared for each of these sections on the basis of cartographic analysis and detailed field work, these files including data related to location, characteristics and inventory of historic elements forming the road's heritage and will subsequently include references to road layout (both longitudinal and cross-sectional), structures (essentially drainage works), auxiliary elements (signalling) and associated buildings (inns, roadworkers’ houses…). Finally, and on the basis of the experience gained during the research, an initial proposal is laid out for the heritage assessment of these assets, considering aspects such as historic, technological and documental singularity which will depend on the degree of transformation and definition of the section in question. 相似文献

The cultural content of ancient sites highlights the importance of light, which is an essential tool for the correct appreciation of the historical value and memory of cultural heritage. This should be a new way to highlight significance of fragments in compliance of the surrounding, which has not the same characteristics, to signal a visual path, creating itineraries that involve the context. Light plays a very important role in creating emotion, suggestion, evocation and supporting the visitor experience. Innovative technological solutions should be designed taking into account the kind of landscape and morphological characteristics of the site. This paper presents the study of a sample of Italian and international case studies, seen in their historical, archaeological and museological aspects. The emphasis is on what should be the most effective lighting system for the monumental sites, one respecting the ruins and the authenticity of the site, while at the same time bringing out their architectural, historical and symbolic significance. 相似文献

Cultural heritage sites and artefacts get a significant added value from high-resolution 3D models. These models are increasingly available due to improvements in technology and to higher integration of survey techniques such as laser scanning and photogrammetry. In this paper we present a case study on the development of a web-based application for user access and interactive exploration of three-dimensional models by providing integrated geometrical and non-geometrical information into an intuitive interface. The main feature of this interactive system is to provide the user with a completely new visit experience based on a free interactive exploration interface of the object (i.e., not constrained by any predefined pathway) and on the opportunity to get more detailed information on specific parts of interest. A parallel aim achieved was to use, in data processing and in the architecture, open source tools and free software, thus providing full transparency on adopted methodology and data processing methods, and a cost effective solution both for server and client. Furthermore, the aspect of data size has been considered using a segmentation and simplification scheme and server-side data management to keep transmission size to a minimum, thus improving access speed. 相似文献

The design approaches of new exterior additions to historic buildings have been among the ongoing debates in the field of architectural conservation. The aim of this study is to develop an assessment method, which can be used to determine the compatibility in architectural expression of the new addition in relation to the characteristics of a historic building. This method is based on the architectural analysis, which includes environmental relations, building-lot relations, mass relations and the facade composition of the historic building both before and after the new addition in relation to the value of a historical building. In this study, a selected group of historic buildings in ?zmir, Turkey with new exterior additions was analysed with regard to their exterior architectural characteristics in order to evaluate the compatibility of the new addition, by employing the use of contemporary conservation principles. The importance of this study is to guide architects to form the basis of a decision for developing an integrated approach in designing new additions in the course of the actual design process. On the other hand, the proposed method can be evaluated as a contribution to the emerging field of heritage impact assessments as well as scientific assistance to local governments to criticize specific projects of cultural heritage assets submitted for appraisal. Analysis results showed that the value of the historic building should first clearly be identified and a new addition should bear the identity of its own period. However, instead of altering the scale or form of the historic building, a new addition should complement and contribute to the sense of proportion, disposition and historical pattern. 相似文献

Historical heritage is proving an ideal field to apply contingent valuation for estimating individual as well as collective preferences as goods tend to be non-market and publicly owned. Yet despite this, findings are seldom used to draw up cultural policies or assess cultural heritage related projects. The current paper thus posits an approach which merges contingent valuation and cost-benefit analysis to design a cultural policy aimed at restoring the urban cultural heritage of the city of Valdivia (Chile). Contingent valuation is used to estimate the expected benefits from heritage for both local residents and tourists visiting Valdivia. We then apply cost-benefit analysis to the findings to evaluate a project to restore the historical ensemble through a non-profit foundation. The originality of the proposal lies in its merging the two approaches and may prove appealing to developing countries in which much of the heritage has been neglected and left to deteriorate, and where few or no resources have been devoted and a lack of effective institutional schemes to address the situation is evident. 相似文献

Virtual restoration of cultural heritage (CH) artefacts is an important task that aims to digitally recreate the original appearance of damaged items. In this paper, a method that can be used for virtual restoration of faces appearing in damaged Byzantine icons is presented. Given a damaged face, the complete three-dimensional (3D) geometry of the face is reconstructed using data from the non-damaged facial parts and the texture of the damaged areas is restored. A key aspect of the proposed method is the use of a customized 3D deformable face model suitable for representing the geometry of Byzantine faces, the so-called Byzantine Style Specific Model (BSSM). A BSSM is generated by enforcing rule-based constraints on a deformable model trained using 3D scans of human faces. The use of a BSSM ensures that the Byzantine style is preserved during the process of shape restoration. 相似文献

Conserving architectural heritage usually requires a multidisciplinary approach involving a variety of professionals and organizations. Since the evaluation of the state of conservation of historical buildings using destructive techniques should be avoided to prevent the integrity of the cultural heritage, the development of non-destructive and non-contact techniques is very important. InfraRed (IR) thermography is a non-destructive powerful tool for fast and accurate building diagnostics. In the investigation of historical structures, where a restoration or conservation treatment can cause irreversible damage to the structure, it is considered to be of most importance. A campaign of thermographic surveys were conducted on a large part of the historical cultural heritage of L’Aquila and its surroundings. In this paper we present the results of the study for the Church of Santa Maria ad Cryptas (XIII century), one of the most ancient buildings in the surroundings of L’Aquila and one of the best examples of Gothic art in Abruzzo, with the aim to evaluate the correspondence between the damage induced by the earthquake and the previous thermographic results, in order to validate the effectiveness of thermography and its role in preventive diagnosis. 相似文献

This paper explores the use of three different forms of valuation and measurement by or on behalf of brands and branded organizations: financial brand valuation; brand equity measurement; and internal social or environmental evaluations. These systems, it is argued, are sites at which possible relationships between economic and other values are explored, and at which understandings of what is valuable emerge in tandem with the means for acknowledging and measuring it. By tracing the contexts and workings of these systems the paper shows how they allow aspects of the social world, including relationships and affects, to be partially absorbed into the brand as values. We argue that in an environment in which ‘value’ is imagined to be diffuse but omnipresent, the proliferation of valuation systems evidences both a requirement for new forms of measurement (capable of capturing multiple forms of value) and a search for novel ways of linking measurement and valuation. The paper concludes with an exploration of how these new ways of linking measurement and valuation may allow economic agency to be recognized and distributed. 相似文献

The aim of this work is to analyse the evolution of the concept of cultural heritage in West European states. In the last decades of the 20th century, the term “heritage” was characterised by expansion and semantic transfer, resulting in a generalisation of the use of this word, frequently used in the place of another, such as, monument and cultural property. However, all these terms are not able to cover the same semantic field. Starting by the reflection on the semantic evolution of the notion of cultural heritage in France, we approach to the international definition of heritage given by the directives, charters and international resolutions in order to define a global outline of the meaning of heritage that is not just limited to a particular national dimension. From a purely normative approach, one went to a less restrictive approach, one based on the capacity of the object to arouse certain values that led the society in question to consider it as heritage and therefore, to a further step in which heritage is no longer defined on the basis of its material aspect. This development has also made it possible to recognise intangible cultural heritage, which was ignored for a long time, as heritage to be protected and safeguarded. 相似文献

Academic studies concerning how climate influences Asian heritage are rare. The object of this study was to utilize the concept of heritage climatology together with a spatial analysis approach that includes respective climate parameter risks to cultural heritage sites. The study area, Tainan City, Taiwan, is in a subtropical zone south of the Tropic of Cancer. Tainan has nearly 300 hundred years of rich history and a multicultural background. This study used maps to gain information about potential climactic threats to Tainan's cultural-historical legacy. There are four kinds of map that use ArcGIS to analyse and demarcate regions not only by climate parameters but also by risk to heritage. These four types of map are climate maps, heritage climate maps, heritage maps and heritage risk maps. Climate maps give the short- to medium-term general status of the climate in Tainan City and thus served as the foundation of the other maps used in this study. Heritage climate maps give data concerning index factors that influence wood and stone materials. Heritage maps show locations of cultural heritage sites on an administrative map and categorize them according to their historic value. Heritage risk maps use accumulated calculations to superimpose the heritage climate map onto the heritage map in order to evaluate the risks to heritage sites in certain areas and categorize the levels of risk. Heritage sites in mountainous areas generally need to be protected from heavy rain, whereas downtown city environments, due to the urban heat island effect, require better protection against heat and cracking. By comparison of our field study results and climate risk maps, we found that in urban areas wooden materials have a higher risk of structural cracking, colour fading and bio-degradation, while coastal areas have a higher risk of weathering of stone materials. 相似文献

Given the civic and social commitments of urban local bodies in developing countries, renovation and maintenance of all heritage buildings and sites is a financially non-viable proposition. Urban planners, therefore, need to take decisions on which heritage sites are to be protected (either in their original form, or with suitable modifications that permit commercial use without destroying their architectural integrity) and the sites to be pulled down, ensuring more efficient land use. Such selection can generate considerable dispute between policy makers and various stakeholders unless the selection process is transparent, consistent and incorporates views of stakeholders. The difficulty in creating an analytical framework to be used for grading is the multiple (often qualitative) attributes of heritage sites. How to combine the performances of heritage structures with respect to these attributes into an aggregative index is a major concern for urban planners and conservationists. This paper argues that the Multicriteria Decision Making (MCDM) method may be a relevant method for grading heritage sites. The application of this method is illustrated for several heritage buildings in Calcutta, India. 相似文献
