Abstract
A method and system are provided for automatically detecting characteristic points of a herringbone fabric with a view to automatically cutting pieces. The herringbone patterns are formed by V-shaped features with vertices that are aligned along a plurality of parallel axes. The method proceeds with a step of acquiring an image of a segment of the fabric, a detection initialization step including, on the basis of predefined parameters or on the basis of the image, acquiring geometric parameters of the herringbone patterns and defining lines of operation perpendicular to the axes of the herringbone patterns, and a step of determining, in the image, coordinates of points of passage of axes of the herringbone patterns along lines of operation via the optimization of a criterion of symmetry of two mirror sub-images acquired along lines of operation.
