In recent years, high-resolution recording of heritage sites has stimulated a lot of research in fields like photogrammetry, computer vision, and computer graphics. Numerous algorithms and methodologies have been proposed in the literature for heritage recording from photogrammetry and laser scanner 3D data. In practice, what a 3D photographer needs for(More)
This paper presents a summary of the 3D modeling work that was accomplished in preparing multimedia products for cultural heritage interpretation and entertainment. The three cases presented are the Byzantine Crypt of Santa Cristina, Apulia, temple C of Selinunte, Sicily, and a bronze sculpture from the 6 century BC found in Ugento, Apulia. The core of the(More)
This paper presents the work that was accomplished in preparing multimedia products for cultural heritage interpretation and entertainment. Data fusion techniques were applied to three cases: the remains of Temple C of Selinunte, Sicily, the Byzantine Crypt of Santa Cristina, Apulia and a bronze sculpture from the 6th century BC found in Ugento, Apulia. It(More)
This paper presents a summary of the 3D modelling work that was accomplished in preparing multimedia products about the Byzantine Crypt of Santa Cristina, Apulia and some partial results on an ongoing project to re-build temple C of Selinunte, Sicily. An effective approach based upon high-resolution photo-realistic texture mapping onto 3D models generated(More)
The Grotta dei Cervi is a complex and fragile Neolithic cave where human presence left a large number of unique pictographs and petroglyphs. Detailed documentation necessitates recording it at different levels of details or spatial resolutions. A general approach would entail a combination of 3D data from different 3D sensors and information from different(More)
Digitally reconstructing a large and complex heritage site, for example a medieval castle, for documentation and virtual reality simulation is a challenging task that requires combining models created by different data sets from several digitisation technologies. Our approach resembles the level of detail (LOD) concept used in visualization of complex(More)
The National Research Council of Canada (NRC) has collaborated with numerous Canadian and international heritage institutions on the development of a complete suite of 3D imaging technologies for archival quality imaging, analysis and display of 3D models of museum objects and heritage sites including ancient crypt and grottos. The technology includes(More)
This paper presents the work that was accomplished in preparing a multimedia CDROM about the history of a Byzantine Crypt. An effective approach based upon high-resolution photo-realistic texture mapping onto 3D models generated from range images is used to present the spatial information about the Crypt. Usually, this information is presented on 2D images(More)
