Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific embodiments.

[0029] figure 1 It is a diagram of the relationship between the parameters of the color space. In CIE 1976 (L * a * b * ) color space, L * is the lightness in the color space, a * is the red / green magenta index value in the color space, b * is the yellow / blue magenta index value in the color space, C * is the chroma value of the color space, h * is the hue angle value of the color space.

[0030] L * 、C * 、h * Chromaticity values ​​are from CIE 1976 (L * a * b * ) color space derived, therefore, a color can be used L * 、a * , b * Indicates that L can also be used * 、C * 、h * express. Use L * C * h * In line with the habit of describing colors in daily life, color correction is easier to understand, more intuitive and easier to control.

Abstract

The invention provides a three-dimensional color space L*C*h* measurement and quantification method for the color of grape wine. The color of the grape wine can be digitally described by using the principle of a color space CIE 1976 (L*a*b*) (also called a CIELAB color space) method; the three physical variables L* value, C* value and h* value are combined to mark the color of any grape wine. Compared with an existing measuring and grading method, the grading method for the color of the grape wine, which is provided by the invention, has the advantage that by use of values of a 'three-dimensional digital coordinate' of the color of the grape wine, the combination of three-dimensional parameters replaces a conventional expression method of 'visual impression, thinking and judgment and language description' of the color.

Description

technical field [0001] The present invention relates to the technical field of detection, more specifically, the present invention relates to a three-dimensional color space L of wine color * C * h * Measurement Quantification Methods. Background technique [0002] With its beautiful body, pleasing color, and remarkable nutritional and health benefits, wine has become a healthy drink that consumers prefer more and more. Color is one of the important quality indicators in wine tasting and grading. It includes information such as anthocyanin and phenolic content, storage age, grape variety, quality and flavor, etc. The quality of wine color will directly affect its overall quality. evaluate. [0003] Generally, according to the color of wine, it can be divided into the following three types: red wine, the color of the wine is purple red, ruby ​​red, garnet, etc.; white wine, the color of the wine is lemon yellow or golden, and it is made of white grape varieties; pink wine...
