2: Obtaining 3D Models With a Hand-Held Camera
Sunday, Tutorial, 10 am - noon
Room 408

How 3D models can be obtained from images acquired with a hand-held camera. The approach is based on advanced automatic techniques that avoid camera calibration and a priori scene knowledge, which gradually retrieve more and more information about the image, the cameras, and the scene. Applications range from archaeology to planetary exploration.

This tutorial is accessible to a wide audience with diverse backgrounds. It requires basic understanding of 3D geometry and perspective projection. A full appreciation of the course requires some knowledge of projective geometry, computer vision, and image-processing techniques.

Feature point extraction and matching, multi-view relations, robust matching, projective structure and motion recovery, self-calibration, bundle adjustment, image-pair rectification, dense stereo matching, multi-view matching, 3D surface modeling, and applications.
