<p>This is a process of the type according to which, by using a contact sensor (12) intended to follow the shape to be scanned (read), this contact sensor (12) is pressed against the article in question with a force (F) of a determined value capable of provoking a local deformation of this article and the coordinates of the contact sensor (12) are recorded at the corresponding moment. According to the invention, two successive coordinate determinations are systematically carried out, one for a first set-point of the application force (F), the other for a second set-point of the latter, and from these two coordinate determinations are deduced mathematically the coordinates corresponding to a set-point value of zero for the application force (F). Application, in particular, to the contour scanning (reading) of circles or of rims of a spectacle frame. <IMAGE></p> |
