Title:
ILLUMINATION SPECTRUM GENERATION METHOD AND APPARATUS, SPECTRUM MATCHING METHOD AND APPARATUS, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/179221
Kind Code:
A1
Abstract:
The present application belongs to the technical field of illumination. Provided are an illumination spectrum generation method and apparatus, a spectrum matching method and apparatus, and a device and a medium. The illumination spectrum generation method comprises: performing, by means of a preset HSB color model, primary color division on HSB information for which matching is to be performed, and determining uniquely corresponding primary color information; forming a color sample set from a plurality of color samples of the primary color information; collecting sample parameters corresponding to the color sample set, so as to obtain a first spectral power distribution function; acquiring a second spectral power distribution function under a fitting light source, and a preset regression function threshold value; performing similarity fitting processing on the first spectral power distribution function and the second spectral power distribution function, so as to obtain a similarity value; and performing similarity determination on the similarity value, so as to determine an illumination spectrum formulation which uniquely corresponds to the primary color information. In the present application, spectrum matching is performed on HSB information by means of an established spectrum formulation library and spectrum matching rule library, so as to determine a unique and high-quality illumination spectrum formulation of an illuminated object.
