Measuring the Appearance Diameter of Yarns Using Visual Information

Abstract

The diameter of the yarn has been defined in the relationship between length and weight of the yarn. However, the diameter of the yarn is different by the convergence condition of the fiber that constitutes the yarn. Then, the new filter is made for the purpose of measuring the appearance diameter of the yarn. In this study, weighting filter to the differential image got by dividing the differential histogram values by the lightness histogram values was made. The measurement method of the appearance diameter of the yarn using this filter was proposed.
