Abstract

A lighting device that emits illumination light from two or more angular directions onto a sample surface to be measured, an imaging optical lens, and a monochrome two-dimensional image sensor are provided. This configuration provides a method and an apparatus that take a two-dimensional image of the sample surface to be measured at each measurement wavelength and accurately measure multi-angle and spectral information on each of all pixels in the two-dimensional image in a short time. In particular, a multi-angle spectral imaging measurement method and apparatus that have improved accuracy and usefulness are provided.

Description

TECHNICAL FIELD

[0001] The present invention relates to any fields, such as paint, coating, textile, printing, and plastic, in which colors of surfaces of objects are measured and to a multi-angle spectral imaging measurement method and apparatus used in measurement and evaluation, and manufacturing based on the measurement and evaluation.BACKGROUND ART

[0002] Design aesthetic is one of the very important added-values of industrial products today. Accordingly, there are many products that have various kinds of texture and surface structures. For example, the outer coating materials of automobiles contain various kinds of effect materials and accordingly their surfaces have extremely minute glitter reflective and granular texture. Furthermore, colors significantly change according to variations in combinations of effect materials, pigments and other materials, layer structures of coating, and geometrical conditions of lighting and observation directions. In particular, the advent of inte...
