Automatic Weave Diagram Construction from Yarn Positional Data of Woven Fabric

We propose a novel automatic weave diagram construction method from yarn positional data of woven fabric. In this work, a set of yarn positional data implies a sequence of center points of a yarn obtained using the yarn tracing method proposed in our previous study. For constructing the weave diagram, the sets of yarn positional data are first divided into warp and weft based on the gradient of a line, which approximates the yarn positional data. The intersections between warp and weft are then calculated using the approximated lines. Then the weave diagram is constructed by comparing the warp positions with the weft positions at all the intersections. The effectiveness of the automatic weave diagram construction method is confirmed by experimentally applying this method to the yarn positional data of a double-layered woven fabric.
