METHODE DE PRE-TRAITEMENT D'UNE IMAGE TRI DIMENSIONNELLE DE LA SURFACE D'UN PNEUMATIQUE A L'AIDE DE DEFORMATIONS B-SPLINE SUCCESSIVES |
摘要 |
<p>A method for inspecting a tyre surface involves comparison with an image of a three-dimensional ("3D") reference surface. The method includes: extracting contours of graphic elements of an image of a 3D profile of a tyre surface to be inspected; locating characteristic points on the image of the tyre surface, and pairing the characteristic points with corresponding reference characteristic points on the image of the reference surface; associating a first reset B-spline surface with the reference surface by associating the reference characteristic points of the image of the reference surface with control points of the first reset B-spline surface; and deforming the reference surface by moving the control points of the first reset B-spline surface so as to superpose the control points on the characteristic points of the tyre surface, in accordance with the reference characteristic points of the reference surface paired with the characteristic points of the tyre surface.</p> |
