High-Resolution 3D Imaging, Modeling and Visualization Research at the National Research Council of Canada

Guy Godin
Senior Research Officer
Visual Information Technology Group
National Research Council of Canada
Ottawa, Ontario, Canada

November 2, 2005
Sage 3510 - 4:00 p.m. to 5:00 p.m.
Refreshments at 3:30 p.m.


The continued increase in capability for gathering high resolution images and models through optical measurement methods opens new applications territories as well as new research problems in 3D imaging and modeling. In this talk, we will provide and overview of recent research results aimed at the acquisition, transformation, and visualization of detailed models. The acquisition of 3D range images using laser-based triangulation has received significant attention over the years, with successful designs and applications gaining acceptance in several application areas. The talk will review a number of key issues in the design and usage of the technology, as well as some limitations of the current techniques. We will also cover techniques for the acquisition and modeling of moving 3D objects using adaptive scanning. The size and complexity of 3D models continues to increase, and requires that issues of interactive data manipulation and display be addressed. The talk will also cover recent work in the interactive display of huge colored and textured models, as well as in foveated stereoscopic displays. Examples of results from recent projects will be shown to illustrate the use of these new methods in the field of 3D cultural heritage documentation.
