Geometry-Corrected Light Field Rendering for Creating a Holographic Stereogram (bibtex)

by Jurik, Joel, Burnett, Thomas, Klug, Michael and Debevec, Paul

Abstract:

We present a technique to record and process a light ﬁeld of an object in order to produce a printed holographic stereogram. We use a geometry correction process to maximize the depth of ﬁeld and depth-dependent surface detail even when the array of viewpoints comprising the light ﬁeld is coarsely sampled with respect to the angular resolution of the printed hologram. We capture the light ﬁeld data of an object with a digital still camera attached to a 2D translation stage, and generate hogels (holographic elements) for printing by reprojecting the light ﬁeld onto a photogrammetrically recovered model of the object and querying the relevant rays to be produced by the hologram with respect to this geometry. This results in a signiﬁcantly clearer image of detail at different depths in the printed holographic stereogram.
