The advent of fast and accurate laser range scanning has brought the promise of automatic creation of 3D models of large structures.
However, there is much manual effort required to move from a 3D point cloud to a complete, texture-mapped model. At the Columbia Robotics
Laboratory, we have been developing methods that are aimed at automating many parts of the 3D modeling pipeline, including
range-range registration, range-image registration, fusion of sensor data (images, range scans, GIS data, video), viewpoint and
lighting independent texture mapping, and mobile robot data acquisition. Our research is being used to assist art historians,
archaeologists and urban planners in building geometrically and photometrically accurate 3D models of large-scale sites, along with visualization
tools that can be used by researchers to explore and understand a site. We present results from modeling historic and archaeological
sites in New York, France, Sicily and South Africa.
Peter K. Allen is Professor of Computer Science at Columbia University. He received the A.B. degree from Brown University in
Mathematics-Economics, the M.S. in Computer Science from the University of Oregon and the Ph.D. in Computer Science from the
University of Pennsylvania, where he was the recipient of the CBS Foundation Fellowship, Army Research Office fellowship and the
Rubinoff Award for innovative uses of computers. His current research interests include real-time computer vision, dextrous
robotic hands, 3-D modeling and medical robotics. In recognition of his work, Professor Allen has been named a Presidential Young
Investigator by the National Science Foundation.
