摘要： Technique for calculating cord parameters of a textile reinforced rubber sheet moving in the machine direction includes: (a) illuminating an area on a side of the sheet with radiation; (b) obtaining a digital image of an illuminated area; (c) generating a digital image of the outer surface; and (d) calculating cord parameters. The elongated textile cords are preferably parallel to each other the elongated textile cords are orientated in a cross direction which is perpendicular to the machine direction. Scanning or static camera with a light source can be employed; the light is directionally perpendicular to the plurality of cords. The digital image comprises a 2D profile, 3D map, or gray scale profile or map and the images are analyzed typically with Fast Fourier transform or sinusoidal fitting techniques. Cord count per unit length, cord spacing, the presence of missing cords, and/or the presence of shifted cords can be determined.
