Abstract

The invention provides a metamerism spectrum generating and evaluating method and system for light source detection. Sampling and screening is performed in a large spectral library, a color science related calculation formula and a single light source based metamerism degree evaluation method are used to achieve metamerism spectrum generation. Sampling is performed on the basis of a standard object color spectrum library; due to the large amount of data, it is possible to screen out a metachromatic color with higher reference value, and the accuracy of a metamerism set is improved. In terms ofgeneration, implementation is convenient. The metamerism evaluation is performed based on a single light source, higher independence is achieved, the dependence on the test light source is lowered, the requirements to evaluate various light sources can be satisfied, and the efficiency of light source evaluation is improved.

Description

technical field [0001] The invention belongs to the technical field of printing light source detection, and in particular relates to a method and system for generating and evaluating metameric spectra for light source detection. Background technique [0002] In the field of color reproduction and light source control, metamerism refers to a pair of colors with different spectral stimuli, which have the same color performance under the same viewing conditions (such as light source or observer), and when one or more of them When these conditions change, the color will change, and there will be a phenomenon that the two colors no longer match. [0003] With the development of the lighting source market, there are many types of light sources nowadays, and it is difficult for the human eye to directly distinguish the quality of the lighting source. We need a scientific and effective method that can help to screen the lighting source. In addition, in the color production industry...
