A CONTOUR EXTRACTION METHOD AND A GEOMETRIC CONTROL METHOD INTEGRATING THIS METHOD; CONTOUR EXTRACTION DEVICE AND GEOMETRIC CONTROL DEVICE INTEGRATING THE EXTRACTION DEVICE

摘要

A contour extraction method comprising the steps of: a) providing an initial image showing an outline; b) using a computer, a refined image is calculated by interpolation of the initial image, using a "sinus cardinal" interpolator; and c) using a computer, the contour is determined from the refined image. Geometric control method of an object incorporating such a method. Contour extraction device for implementing the contour extraction method, and geometric control device incorporating such a contour extraction device.
