Abstract
A method for checking tyres. A shift is determined along an acquisition direction between an acquisition point on a surface of a tyre to be checked and a position occupied by the acquisition point following a rotation of the tyre about its rotation axis. A linear laser beam is projected on a linear portion of surface of the tyre, and propagates in a direction parallel to the acquisition direction. A matrix image of a matrix portion of surface of the tyre containing the linear portion of surface is acquired; the image containing a laser line reflected by the linear portion of surface. A sub-portion of the matrix image is determined as a function of the determined shift, containing the reflected laser line. The sub-portion of the matrix image is then processed to determine an elevation profile of the linear portion of surface.
