One-shot color mapping imaging system of light direction extracted from a surface BRDF
Hiroshi Ohno
Abstract
The bidirectional reflectance distribution function (BRDF) describes several features of a material surface. A one-shot imaging system is proposed here to obtain an in-plane color mapping of light direction corresponding to surface BRDF distribution. Measurement of a surface inclination angle distribution and detection of microstructure on material surfaces are shown to be attainable by the proposed imaging system.
