Yarn break detection using an optical method in real time

摘要

In the process of the production of yarn, the breakage rate is an important index of the quality of the yarn. In this paper, an optical method to detect breakage of moving yarns automatically in the weaving process is proposed. With a line laser illuminating the moving yarns, a linear CCD camera is used to capture the images. Then the original captured image is converted to a binary image, and the number of the connected component is calculated. By analyzing the connected component number, the yarn break is detected, and then the yarn break situation is obtained. Experiments have been performed, and the results proved that the proposed method is effective. (C) 2017 Optical Society of America
