Abstract[English]
A method (6) for inspecting an ophthalmic lens (2), in particular a contact lens such as a soft contact lens (2), in an automated lens manufacturing process is disclosed. The method comprises the steps of acquiring (60) a plurality of images containing the ophthalmic lens (2) to be inspected as an imaged ophthalmic lens (2), wherein each image (4) of the plurality of images is of a different image type, registering (63) the plurality of images by applying a registration function to each image (4) of the plurality of images to obtain registered images, determining (64), based on the registered images, whether the ophthalmic lens (2) complies with predetermined specifications, and updating (62) the registration function to compensate for possible changes in the acquisition of the plurality of images. Updating (62) the registration function is performed during the automated lens manufacturing process.[French]
L'invention concerne un procédé (6) d'inspection d'une lentille ophtalmique (2), en particulier d'une lentille de contact telle qu'une lentille de contact souple (2), dans un procédé de fabrication automatisée de lentille. Le procédé comprend les étapes consistant à : acquérir (60) une pluralité d'images contenant la lentille ophtalmique (2) à inspecter en tant que lentille ophtalmique imagée (2), chaque image (4) de la pluralité d'images étant d'un type d'image différent; enregistrer (63) la pluralité d'images en appliquant une fonction d'enregistrement à chaque image (4) de la pluralité d'images pour obtenir des images enregistrées; déterminer (64), sur la base des images enregistrées, si la lentille ophtalmique (2) est conforme à des spécifications prédéterminées; et mettre à jour (62) la fonction d'enregistrement pour compenser des changements possibles dans l'acquisition de la pluralité d'images. La mise à jour (62) de la fonction d'enregistrement est effectuée pendant le processus de fabrication automatisée de lentille.
