Title:
タイヤのトレッドデザインを形成する基本的パターンを識別すると共に規定する方法
Document Type and Number:
Japanese Patent JP5868987
Kind Code:
B2
Abstract:
A method for inspecting tire tread, having circumferentially juxtaposed elements separated by identically shaped boundaries and having patterns arranged in a predetermined sequence, includes: acquiring an image of a surface of the tire tread, the image including pixels associated with a light-intensity level; transforming the image by circumferentially offsetting pixels located axially at a same distance (x1, x2) from a given circumferential reference (OY), by an inverse (−y1, −y2) of a circumferential offset (y1, y2) with respect to an axial line (OX) of a point (P1, P2) located on a boundary line of known shape at the same axial distance (x1, x2) from the circumferential reference (OY), such that boundaries between elements appear as straight traces orientated in an axial direction; and analyzing the image to identify points located on an axially orientated straight line, the points being treated as points located on a boundary line between two elements.
