Abstract:

In order to reduce the impact of fabric skew on automatic detection, fabric skew and texture direction are detected by Radon transform for fabric image. Firstly an image of plain fabric is simulated by computer programming with same parameter value of yarn diameter and yarn space. Then the simulated image is transformed by Radon projection. The relationship between direction of yarn and texture and projection curve peaks is analyzed. Finally, for images of ten fabric sample, the direction of warp yarn and weft yarn, texture direction, the angle between warp yarn and weft yarn are analyzed. Comparison with results by visual testing shows the method in this paper is more favorable.
