摘　　要：应用数字色彩传感器和微控制器设计一种油脂颜色检测实验装置,检测输出油脂颜色的三基色(红、绿、蓝)信号,即RGB值。为避免RGB模型的缺点,将油脂颜色检测值转换到与设备无关的CIE表色系统,完成由RGB值向CIE–XYZ值、CIE–L*a*b*值的转换,并采用颜色检测组件HDJD–JD02对颜色模型转化公式进行校正。结果表明,油脂颜色可以基于光学和色度学理论进行描述,并可以转换到其它颜色空间。We designed a kind of oil color detection experimental device with digital color sensor and MCU, the detection output three primary colors of oil （ red, green, blue ） signal, i.e. RGB values. To avoid the disadvantages of the RGB model, oil color detection values were converted to a deviceindependent CIE color system, to obtain the CIE-XYZ values and CIE-L^＊a^＊b^＊ values which were conversion formula.The results showed that the oil color could be described based on optical and color theory, and could be converted to other color spaces.
