Abstract
A method is proposed for obtaining surface orientations of transparent obje cts by use of polarization in highlight. Since the highlight, the specular component of light; reflected from objects, is observed only near the specu lar direction, it reveals only limited parts of an object's surface. To obt ain the orientations of the whole surface of an object, we employ a spheric al extended light source. We report the experimental apparatus, a shape rec overy algorithm, and a performance evaluation.
