The National Research Council in Canada (NRCC) has created a framework for gleaning information from very large TLS and imagery datasets, an evolution demonstrated in the Erechtheion project. Cultural heritage has been a central factor in the NRCC research and development program in 3D technologies. Erechtheion is on the Acropolis, next to the Parthenon in Athens, Greece, whos refurbishment began in 1987. The 'Porch of the Maidens' is on the north side and consists of six draped female figures. NRCC has created algorithms for 3D-image processing, management and real-time visualization as part of Atelier3D.ca, a general framework evolved for acquisition, processing, modeling, analysis and visualization of very large 2D/3D datasets created from 3D point-clouds and imagery. Atelier 3D.ca allows view-dependent, real-time visualization of multi-resolution models. Algorithms have been created for displaying these datasets interactively at full resolution on inexpensive laptops or desktop computers. |
