Research Results

<p>Digital technologies are now mature for producing high quality digital replicas of Cultural Heritage (CH) artefacts. The research results produced in the last decade have shown an impressive evolution and consolidation of the technologies for acquiring high-quality digital 3D models (3D scanning) and for rendering those models at interactive speed. Technology is now mature enough to push us to go beyond the plain visualization of those assets, devising new tools able to extend our insight and intervention capabilities and to revise the current consolidated procedures for CH research and management. The paper presents a few recent experiences where high-quality 3D models have been used in CH research, restoration and conservation. These examples constitutes a broad review of different uses of digital 3D<br />assets in the CH domain.</p>

AbstractHistorical costumes are part of cultural heritage. Unlike architectural monuments, they are very fragile, which exacerbates the problems of their protection and popularisation. A big help in this can be the digitisation of their appearance, preferably using modern techniques of three-dimensional representation (3D). The article presents the results of the search for examples and methodologies of implementing 3D scanning of exhibited historical clothes as well as the attendant problems. From a review of scientific literature it turns out that so far practically no one in the world has made any methodical attempts at scanning historical clothes using structured-light 3D scanners (SLS) and developing an appropriate methodology. The vast majority of methods for creating 3D models of clothes used photogrammetry and 3D modelling software. Therefore, an innovative approach was proposed to the problem of creating 3D models of exhibited historical clothes through their digitalisation by means of a 3D scanner using structural light technology. A proposal for the methodology of this process and concrete examples of its implementation and results are presented. The problems related to the scanning of 3D historical clothes are also described, as well as a proposal how to solve them or minimise their impact. The implementation of the methodology is presented on the example of scanning elements of the Emir of Bukhara's costume (Uzbekistan) from the end of the nineteenth century, consisting of the gown, turban and shoes. Moreover, the way of using 3D models and information technologies to popularise cultural heritage in the space of digital resources is also discussed.

Digital technologies offer a new way to communicate and experience cultural heritage. It is now becoming possible to virtually recreate the original appearance of cultural monuments and enable the users to take virtual walks exploring interactive 3D models of objects preserved only in remains. Virtual Reality (VR) is a technology that transfers the users to a different place and time through devices called Head Mounted Displays (HMD) and enables a total immersion in another reality.

Metric surveys are a key component in Cultural Heritage. Metric surveys are in fact a basic input for a wide range of activities, from documentation to study, from restoration to valorization, that rely on the current condition of the monument. In recent years, laser scanning and, more recently, digital photogrammetry offered new perspectives, widening the perspectives of 3D Cultural Heritage recording. Digital technologies provide new ways to collaborate, record excavations, and restore artifacts, and in such a way they are transforming the way Cultural Heritage practitioners (researchers, archaeologists, curators) work. This paper attempts to review the methods for 3D digitization that are today available and discuss the possible use of 3D models beyond the pure extraction of reliable and accurate measures.

AbstractRomania, due to its historical background, has many vestigial belongings to the cultural heritage, out of which the most noticeable (by number, age, architecture, symbolism and representation) are the wooden churches. Under these circumstances the role of the current study is to emphasize certain practical aspects (focused on the need to assess, preserve, restore and valorize) regarding the use of modern technology based on photogrammetry and 3D scanning. The case study was represented by the “Saint Martyrs Constantin Brȃncoveanu and His Sons” wooden church from Oradea Municipality, Bihor County, Romania; the edifice being included on the list of historical monuments ever since 2010. The final goal being to create 3D models for both the exterior and interior of the monument for research, restoration in case of need, sharing for education, entertainment, tourism purposes etc.

Metric surveys have a key role in managing Cultural Heritage. They are needed for a wide range of activities like documentation, study, restoration, and valorization. The importance of the 3D description of objects is widely accepted considering costs/benefits ratio and the opportunities it offers. In recent years, laser scanning and digital photogrammetry offered new perspectives, widening the options in 3D CH recording. Scientific research tends to see their integration as the best approach to CH description. 3D surveys are offering extra opportunities respect to the traditional production of metric supports as 3D models are the ideal base for true 3D information systems and open the way to immersive virtual reality environments. Digital technologies provide new ways to collaborate, record excavations, and restore artifacts in such a way, they are transforming the way CH practitioners work. This chapter attempts to review the methods for 3D digitization that are today available and discuss the possible use of 3D models beyond the pure extraction of reliable and accurate measurements.

In the recent years, mature technologies for producing high quality virtual 3D replicas of Cultural Heritage (CH) artefacts has grown thanks to the progress of Information Technologies (IT) tools. These methods are an efficient way to present digital models that can be used with several scopes: heritage managing, support to conservation, virtual restoration, reconstruction and colouring, art cataloguing and visual communication. The work presented is an emblematic case of study oriented to the preventive conservation through monitoring activities, using different acquisition methods and instruments. It was developed inside a project founded by Lombardy Region, Italy, called “Smart Culture”, which was aimed to realise a platform that gave the users the possibility to easily access to the CH artefacts, using as an example a very famous statue. The final product is a 3D reality-based model that contains a lot of information inside it, and that can be consulted through a common web browser. In the end, it was possible to define the general strategies oriented to the maintenance and the valorisation of CH artefacts, which, in this specific case, must consider the integration of different techniques and competencies, to obtain a complete, accurate and continuative monitoring of the statue.

Numerous software solutions that implement the Structure-from-Motion/Multi-View Stereo (SfM/MVS) 3D reconstruction approach have been made available during the last decade. These allow the production of high quality in terms of geometry and colour information 3D models with the use of unordered image collections that depict a static scene or object from arbitrary viewpoints. Nowadays SfM/MVS-based 3D reconstruction approaches constitute a popular solution in a variety of applications within the cultural heritage domain. As with all 3D reconstruction approaches it has its limitations and application challenges. In this work, the authors attempt to compose a set of guidelines that are based on the important outcomes of important published works that propose solutions that overcome the various challenges introduced by non-friendly surface types.

3D Digitisation

In the era of the global pandemic caused by the COVID-19 virus, 3D digitisation of selected museum artefacts is becoming more and more frequent practice, but the vast majority is performed by specialised teams. The paper presents the results of comparative studies of 3D digital models of the same museum artefacts from the Silk Road area generated by two completely different technologies: Structure from Motion (SfM)—a method belonging to the so-called low-cost technologies—and by Structured-light 3D Scanning (3D SLS). Moreover, procedural differences in data acquisition and their processing to generate three-dimensional models are presented. Models built using a point cloud were created from data collected in the Afrasiyab museum in Samarkand (Uzbekistan) during “The 1st Scientific Expedition of the Lublin University of Technology to Central Asia” in 2017. Photos for creating 3D models in SfM technology were taken during a virtual expedition carried out under the “3D Digital Silk Road” program in 2021. The obtained results show that the quality of the 3D models generated with SfM differs from the models from the technology (3D SLS), but they may be placed in the galleries of the vitrual museum. The obtained models from SfM do not have information about their size, which means that they are not fully suitable for archiving purposes of cultural heritage, unlike the models from SLS.
