As can be deduced from the work carried out in different projects, the objective of our 3D modelling laboratory is to examine the capacity of 3D laser scanner systems to model archaeological artefacts and compare the results to those obtained by photogrammetry, and to optimise registration by combining and innovating in both technologies. Another archaeological area which we have begun to investigate...
The Lorsch Abbey World Heritage Site is a good example for a detailed London Charter implementation guideline. The information system attempted here strives for a combination of architectural 3D-models based on physical remains with historical and recent source materials. It needs to be suited for sites with heterogeneous and sparse sources, which heavily rely on the interpretation and the possible...
This paper describes the 3D digital documentation of a highly significant cultural heritage object from the Melanesian Southwest Pacific, held in the ethnographic collections of the British Museum. The object, which dates from about 1910, is a large plank-built war canoe from the island of Vella Lavella in New Georgia, Solomon Islands. 3D laser scanning is paired with anthropological research, which...
Virtual restoration of Cultural Heritage (CH) artefacts is an important task that aims to re-create the original appearance of damaged items. In this paper we describe a method that can be used for virtual restoration of faces appearing in cultural heritage artefacts. Given a damaged face appearing in a 2D image we estimate the complete 3D shape of a face using data from the non-damaged face and we...
In this paper we describe part of the MediaEvo project on a Digital Heritage application aimed to serve as an edutainment tool. Visitors are able to virtually explore the reconstructed heritage environment of Otranto town and learn about the medieval world through a virtual experience. The project aims to identify the methodologies related to interactive learning and an approach oriented to the instructive...
On the eve of the great earthquake of 1st November 1755, Lisbon was one of the most populated cities in Europe, a major sea port, international trading station and the political heart of an empire that extended from India to Brazil. Portrayed by some travellers and foreign residents as a mixture of abject misery, extreme religious devotion and baroque opulence and extravagance, the old Lisbon became...
We reconstructed a three-dimensional tableau from a single realist painting-Scott Fraser's Three way vanitas (2006)-based on multiple stereo reconstruction applied to the direct image and the images in three plane mirrors depicted within the painting. The tableau contains a carefully chosen complex arrangement of objects including a moth, egg cup, and strand of string, glass of water, bone, and hand...
This paper presents some experiments on different image processing techniques combined and adapted to define a procedure aimed at improving the readability of ancient degraded documents. The focus is on documents affected by the bleed-through effect, which significantly reduces readability. The availability of the recto and verso scans of any single page is assumed. The proposed procedure is composed...
As the number of cultural institutions' Websites which present their digitised collections online is increasing, users are expecting and demanding more sophisticated information from these presentations. The use of these resources has not been sufficiently tested yet with any systematic research study. This paper presents the results of an ongoing research analysing the real use of the digital resources...
The Macao Museum of Prehistoric Art and Sacred is developing a strategy which sees the space of the museum as a place of interactivity. More than an audience we are interesting in developing the role of users, who through practice and a engaging visit build their own learning. In these terms we are interconnecting elements that relate with heritage, IT technology, and Intermedia art. All this terms...
We present a visual computing effort to realistically and interactively simulate and visualize aspects of human motion behavior in virtual 3D environments. It allows virtually changing the infrastructure of a layout and assessing the consequences in terms of motion paths and visibility (where will people look at?). We first create a virtual 3D model of an infrastructure with photogrammetric reconstruction...
Cultural heritage presentation is a topic we at CTU Prague deal with for more than ten years. In this paper we present our experience with user interface design where serious games paradigm has been utilized. The survey of selected projects represents various technologies and approaches for cultural heritage data handling that includes data acquisition, presentation, interaction and educational issues...
In this paper we are presenting Cultural Heritage Layers, an approach that enables the visualization of historic media like drawings, paintings and photographs of buildings and historic scenes seamlessly superimposed on reality via video see through using X3D. This enables simple, inexpensive and sustainable Augmented Reality applications in the cultural heritage and architectural area based on industry...
This paper discusses a virtual world (VW) environment, called travel in Europe (TiE), aimed at promoting a meaningful interaction with artistic heritage. TiE is based on contents collected by cultural experts, which are offered to the user through an online 3D VW. In TiE users live challenging and compelling experiences by interacting with virtual representations of the European heritage. The paper...
