Exploiting Mirrors in Interactive Reconstruction
with Structured Light

Emric Epstein, Martin Granger-Piché, and Pierre Poulin
Proc. Vision, Modeling, and Visualization 2004, November 2004


This paper describes how a mirror can be integrated as another view and another source of light patterns in an interactive reconstruction system with structured light, where the object, the camera, and the mirror can move. We show how a single pass of structured light can provide 3D points to accurately estimate the pose of a mirror, while also reconstructing 3D points on the object. We develop new structured light patterns that are unaffected by the reversed order created by some mirror configurations. We also describe hardware rendering support to avoid conflicting emitted/captured light patterns, and demonstrate how all the proposed realizations extend naturally for multiple mirror configurations. We finally conclude with results, discuss limitations, and suggest further improvements.
