Automatic weave diagram construction from yarn positional information of weft-knitted fabric

In this paper, a novel automatic construction method of a weave diagram using yarn positional information of a weft-knitted fabric is proposed. The yarn positional information is a sequence of the center points of the yarn in this study, which is obtained using a yarn tracing method proposed in my previous study. Constructing a weave diagram corresponds to identifying the stitch type at each stitch of the knitted fabric. For constructing a weave diagram, first, the position of each stitch is detected by investigating the cross points between the yarns. Then, the types of stitches are identified by investigating which stitch the stitch intersects with. The validity of the proposed automatic weave diagram construction method is confirmed by experimentally applying the method to yarn positional information of a plain knitted fabric.
