		- New Opportunities in 3D Scene Modeling"

ABSTRACT:

The talk describes a general approach for scanning and visualizing
panoramic (360 degrees) indoor or outdoor scenes. It combines range data
acquired by a laser range finder with color pictures acquired by a
rotating CCD line camera. The talk describes the stereo architecture of
the panoramic camera and its calibration, coordinate systems of both
sensors, specifies the fusion of range and color data acquired by both
sensors, and reports on three alternatives for visualizing the generated
3D data set.

The preferred approach utilizes an improved method for calculating the
spatial (geometric) correspondence between laser diode of the laser range
finder and the focal point of the rotating CCD line camera.

Examples in the talk illustrate outdoor scenes in Auckland/New Zealand,
and a major project on 3D documentation of the castle Neuschwanstein in
Bavaria/Germany.

Biography:

Professor Reinhard Klette is with the Department of Computer Science and
the Center for Image Technology and Robotics (CITR) at The University of
Auckland (New Zealand), where he teaches classes in picture processing,
analysis, and computer vision. Prior to 1996 he was professor for computer
vision at the Technical University of Berlin, and prior to 1990 professor
at the Academy of Sciences in Berlin. He held visiting positions at the
University of Maryland at College Park, the Mathematical Center "Stefan
Banach" at Warsaw, the International Computer Science Institute at
Berkeley, the University of Otago at Dunedin, the University of Western
Australia (Perth), the University of Western Ontario (London), Kiel
University, and G?ttingen University. He is co-author of the book "Digital
Geometry - Geometric Methods for Digital Picture Analysis" (with Azriel
Rosenfeld), the "Handbook of Image Processing Operators" (with Piero
Zamperoni) and of the book "Computer Vision - Three-Dimensional Data from
Images'' (with Karsten Schl\"uns and Andreas Koschan). Dr. Klette has
published papers in digital geometry for more than twenty years and his
projects in that area have often been published jointly with colleagues
from different groups worldwide.  He contributed to early studies on
parallel picture analysis, theoretical fundamentals of digital geometry,
and algorithm design and analysis, and particularly to evaluations of
algorithms in digital geometry, applying multigrid convergence as a
theoretical and experimental criterion. He contributed to several
applications of computer vision or picture analysis technologies, and to
basics and applications of panoramic imaging.
