摘要
The invention relates to a method characterized in that it comprises—a step (E1) of calibrating a device, whereby—a galvanometric head illuminates along two axes a calibration plate, situated at a depth, in order to illuminate a plurality of determined points of the calibration plate, while a camera observes said calibration plate, a control unit establishing a relationship between, on the one hand, the position of illumination of each of the illuminated points of the calibration plate at the depth, and, on the other hand, the position observed by the camera of the illuminated points; the calibration plate being successively positioned at a plurality of depths during the calibration step so as to allow a plurality of illuminations by the head, of observations by the camera and of relationships to he established by the control unit; the control unit establishes a correspondence relationship,—a step (E2) of determining the three-dimensional shape of the surface that is to be ablated, from the calibration step (E1), by triangulation, and—a step (ES) of ablating the three-dimensional surface whereby the control milt controls the galvanometric head as a function of the determined shape of the surface in order to focus and to direct, along axes that define a plane and to a depth, the beam onto the surface that is to be ablated. The invention also relates to a device for implementing an aforementioned method,
