【摘要】 用机器视觉分析、处理图像在农产品加工的分类和控制或遥感的测量中有诸多的应用价值，颜色的分类就是其中之一。本文根据ＣＩＥ色度学理论，研究在不同照明系统下，两色混合图像中，颜色分类的通用测量方法，利用这种方法测量两种颜色之比，并达到一定的精度。研究结果表明，根据图像色调的分布，自动选取颜色的阈值，能部分地消除非标准光源对测量结果的影响。更多还原

【Abstract】 おith respect to CIE chromatics theory, a classifying color means, which would be for general color measurement under different illumination, is discussed in the paper. By this means and a machine vision system certain precision to measure the ratio of two colors can be attained. The results show that the influences of unstandard illumination would be diminished partly by automatically selecting threshold value, according to hue distribution of the image.更多还原
