Abstract:

In the process of production of yarn, the breakage rate is an important index of the quality of yarn. In this paper, an optical method to detect the break of the 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 break yarn situation is obtained. Experiment works have been performed, and the results proved that the proposed method is effective.
