hsi网格化模型构建及其等明度等彩度等色相色谱的可视化方法
技术领域
1.本发明涉及hsi网格化模型构建及其等明度等彩度等色相色谱的可视化方法，属于纺纱色谱技术领域。


背景技术：

2.hsi(hue、saturation and intensity)颜色模型属于强度/饱和度/色调(intensity/saturation/hue)型颜色空间，它从人的视觉系统出发，用色调(hue)、色饱和度(saturation或chroma)和色亮度(intensity或brightness)来描述颜色。如图1所示，hsi颜色空间是以色相环作为圆周，彩度作为半径，明度作为高的双圆锥模型，其中色度的取值范围是0
°
～360
°
，彩度取值范围是0～1，明度取值范围是0～1。标准八基色rygcbmwk的rgb值及其在hsi颜色空间的颜色值如表1所示。

[0004][0005]
hsi空间全色域色彩的可视化对于运用色彩变化规律进行色彩设计是非常重要的，并且hsi颜色空间符合人对色彩的视觉感受因而被广泛运用。但现有hsi颜色空间理论存在以下问题：
[0006]
1、虽然基于极坐标体系定义了hsi颜色模型的色相角、彩度和明度及其取值范围，但未建立hsi颜色模型的网格化理论，缺少从色相角、彩度和明度等三个维度对hsi颜色模型色彩分布规律的定量分析；
[0007]
2、虽然基于rgb颜色模型推演了hsi颜色模型，但未构建能将色相角、彩度和明度相互关联的hsi网格化颜色模型，无法对hsi颜色空间的全色域色谱进行数字化表达。
[0008]
3、虽然基于hsi颜色模型定义了等明度面、等色相面和等彩度面，但未给出hsi颜色模型等明度面、等色相面和等彩度面上网格点阵列色谱的计算方法。
