HSL Chromaticity Characteristic of Green Jadeite Jade

  • 摘要: 目前的翡翠市场暂时未建立起评价绿色翡翠颜色的统一标准。基于HSL色度学的绿色翡翠颜色分级理论与技术,本研究拟采用机器视觉法。根据色度学原理,以HSL颜色空间模型为理论基础,在色温5 500 K白光光源下,通过彩色数码摄像头采集绿色翡翠样品的色彩,对每个样品图像颜色进行HSL值分析,从而量化绿色翡翠颜色的参数指标,并将所得到的HSL数值按不同色相(H)投点到二维的SL图像上,得到翡翠绿色色彩的HSL分布区间及其色度学特征,确定绿色翡翠各种色彩类型的HSL值边界,从而区分和确定绿色翡翠的色调,划分绿色翡翠的颜色浓度和明亮度,量化绿色翡翠的色彩类型。
    Abstract: The colour of jadeite jade is one of the important linkages for evaluation of quality and value of jadeite jade. In recent years, scholars have carried out many studies on the evaluation of jadeite jade colour and have made certain achievements. However, these achievements have obviously not been applied or promoted in the market, because these evaluations are based on instrument indexes. This research is based on the principle of colorimetry, using the HSL colour space model as the theoretical basis. Under the 5 500 K white light source, the authors collected photos of green jadeite jade samples by colour digital camera, and analyzed the HSL value of each sample. The authors quantified the green jadeite colour parameters in HSL value and got the HSL distribution. Based on these analysis, the authors obtained the threshold of HSL value of 9 kinds of green jadeite jades:melon green, emerald green, bright green, yellow green, bean green, light bean green, light green, pale green and grey green, and the chromaticity characteristics of these green jadeite jade are determined. The authors expect to find out a simple, convenient and scientific method for the evaluation and grading of colour of green jadeite jade.
