Title (EN) A METHOD OF DETERMINING THE POSITION OF AN OPTICAL LENS MEMBER
(FR) PROCÉDÉ PERMETTANT DE DÉTERMINER LA POSITION D'UN ÉLÉMENT DE LENTILLE OPTIQUE
Abstract:
(EN) Method implemented by computer means, for determining the position of an optical lens member having a surface placed on a lens blocking ring, the blocking ring comprising a bearing zone arranged to bear at least partially a placed known surface of the optical lens member when said known surface of the optical lens member is placed on the lens blocking ring and hold by a force applied on the optical lens member, the method comprises finding a trio of points of the bearing zone that forms a triangle comprising the projection on the main plane of the point of application of said force; and a position of the optical lens having a virtual contact between the placed known surface and the ring at the location of said trios of points.
(FR) L'invention concerne un procédé mis en œuvre par un moyen informatique, destiné à déterminer la position d'un élément de lentille optique présentant une surface placée sur une bague de blocage de lentille, la bague de blocage comprenant une zone de support agencée pour soutenir au moins partiellement une surface connue placée de l'élément de lentille optique, lorsque ladite surface connue de l'élément de lentille optique est placée sur la bague de blocage de lentille et maintenue par une force appliquée sur l'élément de lentille optique, le procédé comprenant la recherche d'un trio de points de la zone de support qui forme un triangle comprenant la projection sur le plan principal du point d'application de ladite force ; et une position de la lentille optique présentant un contact virtuel entre la surface connue placée et la bague à l'emplacement desdits trios de points.
