Complex color non-uniformity and surface texture
Original language description
The article explains the basic concepts of colorimetry and deals with issues of assessment reflectance quality of special plaster coatings in accordance with current methods of measuring spectral reflectance of the International Commission on Illumination (CIE). The results demonstrate that in the case of coatings with high gloss values (more than 70 GLS in the geometry 60) leads to a linear increase of specific purity depending on the specific increase luminance in the case of measuring devices fitteddiffusion geometry. Conversely, if the angle-measuring instrument fitted geometry values of specific purity correlated with values of specific brightness. Analysis BRDF, respectively BSRDF function showed that the previously used dichromatic spectral reflectance model must be extended by an additional parameter explaining the correlation between chroma and lightness at the diffusion measurement geometry.
