HSV gridding model construction and chromatography visualization method

Abstract

The invention relates to HSV grid model construction. Based on an HSV color space of a regular hexagonal prism, decomposing the HSV color space into six regular triangular prism color general models; constructing a gridding model capable of performing double coupling association on three dimensions such as hue angle, chroma and lightness by gridding three bottom edges and edge heights of the regular triangular prism color general model; and the eight-primary-color HSV gridding model is constructed through integration and expansion. Based on the eight-primary-color HSV gridding model, digital expression of color values of all grid points of the HSV color model is achieved through grid point coordinates, and construction of a grid point array model and a matrix of an equal-brightness surface, an equal-hue surface and an equal-chroma surface of an eight-primary-color HSV color space is efficiently achieved through the eight-primary-color HSV gridding model. Therefore, the digital expression and visualization of the eight-primary-color HSV equal-brightness surface, equal-hue surface and equal-chroma surface grid point chromatography are realized.

Description

technical field [0001] The invention relates to the construction of an HSV grid model and a chromatogram visualization method, and belongs to the technical field of spinning chromatogram. Background technique [0002] HSV in the HSV color model is Hue, Saturation, Value. The HSV color model is a model that uses the hue circle as the circumference, the chroma as the radius, and the lightness as the height of the cylinder. The shape of the HSV color model is a cylinder composed of space colors, and its schematic diagram is as follows figure 1 shown. The HSV color space is a cylinder, the lightness value of the top surface is 1, and the lightness value of the bottom surface is 0. When the lightness value changes from 1-0, the lightness value of each hue on the top surface gradually decreases from 1 to 0. During the process, everything turns black, and on the central axis of the cylinder, it gradually changes from white to black during the process from the center of the upper...
