Title (EN) METHOD OF INSPECTING AN OBJECT WITH A VISION PROBE
(FR) PROCÉDÉ D'INSPECTION D'UN OBJET À L'AIDE D'UNE SONDE VISUELLE
Abstract:
(EN) A method of inspecting a hole in an object with at least one camera probe mounted on a coordinate positioning machine. The method comprises: for a plurality of different viewpoints obtaining at least one image of a silhouette of the hole from a first end of the hole, so as to obtain a set of silhouette images of the hole, the hole being backlit so as to form said silhouette, and using said set of silhouette images of the hole to infer at least part of the boundary of the hole at a given height.
(FR) L'invention concerne un procédé d'inspection d'un trou dans un objet à l'aide d'au moins une sonde de prise de vues installée sur une machine de positionnement par coordonnées. Le procédé comprend les étapes consistant à : pour une pluralité de différents points de vue, obtenir au moins une image d'une silhouette du trou à partir d'une première extrémité du trou, de manière à obtenir un ensemble d'images de silhouette du trou, le trou étant rétro-éclairé à de manière à former ladite silhouette, et utiliser ledit ensemble d'images de silhouette du trou afin de déduire au moins une partie de la limite du trou à une hauteur donnée.
