Single-Shot Photometric Stereo by Spectral Multiplexing (bibtex)
by Graham Fyffe, Xueming Yu, Paul Debevec
Abstract:
We propose a novel method for single-shot photometric stereo by spectral multiplexing. The output of our method is a simultaneous per-pixel estimate of the surface normal and full-color reflectance. Our method is well suited to materi- als with varying color and texture, requires no time-varying illumination, and no high-speed cameras. Being a single- shot method, it may be applied to dynamic scenes with- out any need for optical flow. Our key contributions are a generalization of three-color photometric stereo to more than three color channels, and the design of a practical six- color-channel system using off-the-shelf parts.
