Image Transformation And Synthesis Methods

US Patent:
6393144, May 21, 2002
Filed:
Oct 15, 2001
Appl. No.:
09/977407
Inventors:
Peter R. Rogina - Martinsville NJ
Michael Ehrlich - Steamboat Springs CO
David MacIntosh - Inverkeithing, GB
Assignee:
WorldScape, L.L.C. - Martinsville NJ
International Classification:
G06K 900
US Classification:
382154, 382276
Abstract:
In a telepresence system, a scene is captured by recording pixel data elements, each associated with a pixel ray vector having a direction and an intercept on an known locus in the frame of reference of the scene. Each pixel data element includes data representing the illumination along the pixel ray vector. For example, the pixel data elements may be captured by operating numerous video cameras pointing in different directions on a spherical locus. A virtual viewpoint image representing the image which would be seen from an arbitrary viewpoint, looking in an arbitrary direction, can be synthesized by determining the directions of synthetic pixel ray vectors from each pixel of the virtual viewpoint image through the virtual viewpoint and the intercepts of these vectors on the locus. Recorded pixel data elements having pixel ray vector directions and intercepts close to those of the synthetic pixel ray vector can be copied or interpolated to provide data representing illumination in the synthetic pixel.
