Refractive Height Fields from Single and Multiple Images
Abstract: We propose a novel framework for reconstructing homogenous,
transparent, refractive height-fields from a single viewpoint. The height-field is imaged
against a known planar background, or sequence of backgrounds. Unlike existing
approaches that do a point-by-point reconstruction – which is known to have intractable
ambiguities – our method estimates and optimizes for the entire height-field at the same
time. The formulation supports shape recovery from measured distortions (deflections) or
directly from the images themselves, including from a single image. We report results
for a variety of refractive height-fields showing significant improvement over prior art.
