Development of an Integrated Measurement System for Cotton Impurity Rate and Color Based on Raspberry Pi
摘要
Abstract
In order to solve the problem of low-cost measurement of cotton impurity rate and color by a single instrument,a Raspberry Pi-based integrated measurement system of cotton impurity and chromaticity is designed and developed.A CMOS camera is used to collect the images of cotton test samples and realize the measurement of impurity quantity and impurity rate(impurity area)of cotton test samples through the visual image-based method.The AS73211 novel XYZ color sensor is used to collect the spectral tri-stimulus values of cotton,which are calibrated by a spectrophotometer,and finally the measurement of the two chromaticity values of the cotton(reflectivity Rd and yellowness+b)under the chromaticity space of Nickerson-Hunter is realized.At the same time,a measurement software interface corresponded by cotton color and impurity is designed to display the results of cotton impurity rate and chromaticity measurement data in real time.The experimental results show that the measurement error of the impurity rate of the system is not more than 0.5%,and the mean value of the color difference between the three stimulus values of the color does not exceed 5,which realizes a low-cost cotton color and impurity measurement system.关键词
