  1. Virtual reassembly and completion of a fragmentary drinking vessel

    Tsiafaki, Despoina; Koutsoudis, Anestis; Arnaoutoglou, Fotis; Michailidou, Natasa
    [EN] A key issue in the study of cultural assets is theiroften fragmentary condition. This causes serious problems and questions regarding theirstudy and presentation. Pottery fragments are the most numerous findings in every excavation. Furthermore, pottery plays an essential role for the reconstruction of the past, since it providesinformation for all aspects of life (private, public, religion, death, economy, society, trade,etc.). Therefore,a thorough study and presentation of pottery fragments contribute to a better knowledge of the past.The focus of this work is the visualisation of an ancient Greek drinking vase, a kantharos, which was unearthed during the excavations at the...

  2. Technical study of Germolles’ wall paintings: the input of imaging technique

    Degrigny, Christian; Piqué, Francesca; Papiashvili, Nutsa; Guery, Julien; Mansouri, Alamin; Le Goïc, Gaëtan; Detalle, Vincent; Martos-Levif, Dominique; Mounier, Aurélie; Wefers, Stefanie; Tedeschi, Cristina; Cucchi, Marco; Vallet, Jean-Marc; Pamart, Anthony; Pinette, Matthieu
    [EN] The Château de Germolles is one of the rare palace in France dating from the 14th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime in the 19th century, the paintings were rediscovered and uncovered in the middle of the 20th century and partly restored at the end of the 1990s. No scientific documentation accompanied these interventions and important questions, such as the level of authenticity of the mural decorations and the original painting technique(s) used in the...

  3. Some notes on the digitalization and the virtual reconstruction of San Chuis Hillfort (Allande, Asturias, Spain)

    Molina Salido, Juana; Jordá Pardo, Jesús F.
    [EN] With the firm conviction that current archaeology needs to use all the tools that computer science provides, we have developed a project for digitising and structuring all the information gathered from the different excavation campaigns carried out in San Chuis hillfort (Allande, Asturias, Spain). In order to do it, we have developed the Spatial Data Infrastructure (SDI) of the hillfort, in order to proceed subsequently to its virtualization. To implement the SDI, we have reinstated the archaeological record in its original coordinates based on the information that we had. This restitution has allowed us to perform the spatial analysis...

  4. From the archaeological record to ArchaeoBIM: the case study of the Etruscan temple of Uni in Marzabotto

    Garagnani, Simone; Gaucci, Andrea; Gruška, Bojana
    [EN] The digital reconstruction of the recently discovered Tuscanic temple of Uni in Marzabotto gave the chance to test the application of the Building Information Modeling (BIM) process to the combined fields of Archaeology and Engineering. In addition to the traditional historic and archaeological analysis, a new methodology in Experimental Archaeology is proposed; it proved to be original and innovative in the examination of the buried building, taking advantage of technologies focused on the architectural reliability validated by inferred digital models. The peculiar aspect of the research involves the elements at the beginning of the process, which consist of foundations...

  5. Evaluation of the effectiveness of HDR tone-mapping operators for photogrammetric applications

    Suma, Rossella; Stavropoulou, Georgia; Stathopoulou, Elisavet K.; van Gool, Luc; Georgopoulos, Andreas; Chalmers, Alan
    [EN] The ability of High Dynamic Range (HDR) imaging to capture the full range of lighting in a scene has meant that it is being increasingly used for Cultural Heritage (CH) applications. Photogrammetric techniques allow the semi-automatic production of 3D models from a sequence of images. Current photogrammetric methods are not always effective in reconstructing images under harsh lighting conditions, as significant geometric details may not have been captured accurately within under- and over-exposed regions of the image. HDR imaging offers the possibility to overcome this limitation, however the HDR images need to be tone mapped before they can be...

  6. Digital Segusio: from models generation to urban reconstruction

    Spanò, Antonia; Chiabrando, Filiberto; Dezzani, Livio; Prencipe, Antonio
    [EN] The reconstructive study of the urban arrangement of Susa in the 4th century arose from the intention to exploit some resources derived from local studies, and survey activities, fulfilled by innovative methods from which the modelling of architectural heritage (AH) and virtual reconstructions are derived. The digital Segusio presented in this paper is the result of intensive discussion and exchange of data and information during the urban landscape documentation activities, and due to the technology of virtual model generation, making it possible to recreate the charm of an ancient landscape. The land survey has been accomplished using aerial and...

  7. Development of a platform recommending 3D and spectral digitisation strategies

    Wefers, Stefanie; Karmacharya, Ashish; Boochs, Frank
    [EN] Spatial and spectral recording of cultural heritage objects is a complex task including data acquisition, processing and analysis involving different technical disciplines. Additionally, the development of a suitable digitisation strategy satisfying the expectations of the humanities experts needs an interdisciplinary dialogue often suffering from misunderstanding and knowledge gaps on both the technical and humanities sides.Through a concerted discussion experts from the cultural heritage and technical domains currently develop a so-called COSCHKR platform (Colour and Space in Cultural Heritage Knowledge Representation) which will give recommendations for spatial and spectral recording strategies adapted to the needs of the cultural heritage application....

  8. 3D visualization tools to explore ancient architectures in South America

    Pierdicca, Roberto; Malinverni, Eva Savina; Frontoni, Emanuele; Colosi, Francesca; Orazi, Roberto
    [EN] Chan Chan is a wide archaeological site located in Peru. Its knowledge is limited to the visit of Palacio Tschudi, the only restored up to now, whilst the majority of the site remains unknown to the visitors. The reasons are manifold. The site is very large and difficult to visit. Some well-conserved architectures, such as Huaca Arco Iris, are very far from the core centre. Furthermore, there are heavy factors of decay, mainly caused by illegal excavations, by marine salt and by the devastating phenomenon of El Niño. For these reasons, the majority of the decorative elements are protected...

  9. 3D visibility analysis as a tool to validate ancient theatre reconstructions: the case of the large Roman theatre of Gortyn

    Manzetti, Maria Cristina
    [EN] With the diffusion of Virtual Archaeology, many projects in the field of Cultural Heritage attempt to virtually reconstruct historical buildings of different types. Unfortunately, some of these 3D reconstructions still have as principal aim to impress the external users, while the correct interpretation of the buildings modeled is much more important in the domain of archaeological research. Still more critical is the situation when we have to encounter a reconstruction of a monument which is not visible anymore, or which consists only of few architectural remains. The main purpose of this paper is to introduce an innovative methodology to...

  10. 3D virtual reconstruction of the choir of the Convent of Santa Clara in Toro (Zamora): recovering a medieval space of female devotion through photogrammetric recording and rendering techniques

    Gutiérrez Baños, Fernando; Morillo Rodríguez, Francisco M.; San José Alonso, Jesús I.; Fernández Martín, Juan José
    [EN] The Convent of Santa Clara in Toro (Zamora) was founded in the mid-13th century. After destruction during the Castilian civil struggles of the last years of this century, its fabric was rebuilt and it was inhabited again by the Clarissan nuns, who still occupy it. Its architecture corresponds for the most part to its early-14th century rebuilding, even though it is concealed by works carried out from the 16th to the 18th centuries, so that it is apparently a Baroque complex. In the 1950s, in the choir of this Medieval hidden structure, a set of wall paintings of the...
