<p>The present invention concerns a method and an apparatus for determining the distortion angles of a moving textile fabric, cloth or the like. Method consisting of forming a real image of the textile, fabric or cloth, illuminated by at least one light source, sampling the said image to form images of successive rectangularly shaped areas, transverse to the moving direction of the textile, fabric or cloth digitizing and storing the corresponding image signals, dividing the said images into rectangular shaped tiles, performing then weft texture modellization and local distortion angles estimation by way of bi-dimensional image transformation of at least part of the aforesaid tiles and determining the global distortion angles of the textile fabric by weighting the local distortion angles estimated on each said tile taken into account. <IMAGE></p> |
