基于机器视觉的单组分染液浓度快速检测方法

针对印染行业的单组分染液浓度的检测需求,提出一种基于机器视觉的对单组分染液浓度进行快速检测的方法.该方法采用颜色亮度可调的背光光源和彩色工业相机搭建机器视觉检测平台,将质量浓度范围在0～0.4 g/L的单组分染液样品通过玻璃皿置于背光光源上进行图像采集和处理,获取染液颜色特征值(R、G、B值),拟合不同光源条件下的R、...

Rapid detection method of single-component dye liquor concentration based on machine vision

A method based on machine vision was proposed to detect the concentration of dye liquor with a single-component for the printing and dyeing industry.With this method,a machine vision detection platform was built with a color adjustable backlight source and an industrial color camera.The single-component dye liquor sample with a concentration range of 0-0.4 g/L was placed on a backlight light source through a glass dish for image acquisition and processing,in order to obtain the color characteristic values of the dye liquor,and to get the relationship between the RGB value and concentration of dye liquor under different light source conditions.Based on Lambert-Beer law,the relational model between the RGB value and dye liquor concentration was built to predict the concentration of dye in the dye liquor.It is verified by experimental fact that for the DRA-3R dye liquor,the minimum value model established under the condition of blue light intensity 50 has the highest prediction accuracy.The absolute value of the average relative error of the results is 3.35%.Experiments show that the method offers fast detection speed and low cost,which provides a certain research base for industrial application of on-line detection of dye liquor concentration.
