Abstract: ince the skew was inevitable during the fabric image collecting,a new method using the texture of fabric to rectify the skew of fabric image was proposed.Based on the principle that the direction of the yarn clearance is accordant with that of the yarn,the skew of the complete fabric image can be correctly rectified when performing rectification of the skew of the yarn clearance.The relation between the rectified angle and the discrete degree of projection brightness of fabric image,and the measurement of the weft density are used to validate the effect of the rectification of the fabric image.The experiments show that an ideal result has been obtained by this method as the precision of rectification reaches 0.05,° and this has laid a foundation for the automatic recognition of the fabric density and the fabric structure.
