Portable On-line Measurement of the Yarn Quality Using CCD Sensors
In this paper, the method of portable on-line measurement of the yarn quality using CCD image sensors is introduced. The obtained coefficients of variation in the yarn diameter through computer and digital image processing techniques are compared with those of using off-line USTERII evenness tester. To a certain extent, avoiding affection of the incident light intensity, the CCD sensors overcome the shortcomings of the conventional photoelectric sensors. Combined with modern control theory, intelligent algorithm is designed to collect and process real-time data of the measuring device. The results of on-line measuring show that the error accuracy is less than 6.5％ in the study. In addition, it is also found that the achieved data from the online device are coherent and correlative with USTER statistical bulletin 2001. Therefore, the development of the portable, higher cost-effective measuring device has a positive role in promoting the textile industry and improving the quality of the yarn.
