Abstract in LaTeX format:
Objects with mirroring optical characteristics are left out of the
scope of most 3D scanning methods. We present here a new automatic
acquisition approach, shape-from-distortion, that focuses on that
category of objects, requires only a still camera and a color
monitor, and produces range scans (plus a normal and a reflectance
map) of the target.

Our technique consists of two steps: first, an improved
environment matte is captured for the mirroring object, using the
interference of patterns with different frequencies in order to
obtain sub-pixel accuracy. Then, the matte is converted into a
normal and a depth map by exploiting the self coherence of a
surface when integrating the normal map along different paths.

The results show very high accuracy, capturing even smallest
surface details. The acquired depth maps can be further processed
using standard techniques to produce a complete 3D mesh of the
