Abstract

Titre : Détermination d'au moins un paramètre optique d'une lentille optique La présente invention concerne un procédé (210), un programme informatique et un dispositif (110) de détermination d'au moins un paramètre optique (220, 220‘, …) d'une lentille optique (112) ainsi qu'un procédé de détermination d'au moins un paramètre optique (220, 220‘, …) d'une paire de lunettes (118), en utilisant le procédé de détermination des paramètres optiques (220, 220‘, …) de la lentille optique (112). Le procédé (210) comprend en l’occurrence les étapes suivantes : a) capture d'au moins une image (234) d'un motif (124) à travers une lentille optique (112), et b) détermination d'au moins un paramètre optique (220, 220, 220‘) de la lentille optique (112) à partir de l'au moins une image (234) du motif (124), où à partir de l'au moins une image (234) du motif (124) présentant une variation observable optiquement, on extrait au moins deux jeux de données (242, 244, 246) de valeurs caractéristiques différentes entre elles de la variation, et on détermine au moins un paramètre optique (220, 220‘, …) de la lentille optique (112) à partir des au moins deux jeux de données (242, 244, 246). La présente invention permet de déterminer avec une précision supérieure au moins un paramètre optique (220, 220‘, …) de la lentille optique (112). De plus, on peut déterminer au moins deux paramètres optiques (220, 220‘, …) de la lentille optique (112) aussi simultanément que possible, de sorte que des modifications qui peuvent survenir entre deux mesures individuelles ne soient pas prises en compte lors de l'évaluation des résultats de mesure, afin d’accélérer ainsi l'évaluation des résultats de mesure et d’obtenir une plus grande précision des résultats de mesure. Figure 1Title: Determination of at least one optical parameter of an optical lens The present invention relates to a method (210), a computer program and a device (110) for determining at least one optical parameter (220, 220',... ) of an optical lens (112) as well as a method for determining at least one optical parameter (220, 220', ...) of a pair of spectacles (118), using the method for determining the optical parameters (220, 220', …) of the optical lens (112). The method (210) in this case comprises the following steps: a) capturing at least one image (234) of a pattern (124) through an optical lens (112), and b) determining at least an optical parameter (220, 220, 220') of the optical lens (112) from the at least one image (234) of the pattern (124), where from the at least one image (234) of the pattern (124) exhibiting an optically observable variation, at least two sets of data (242, 244, 246) with different characteristic values of the variation are extracted, and at least one optical parameter (220, 220', ... ) of the optical lens (112) from the at least two sets of data (242, 244, 246). The present invention makes it possible to determine with greater accuracy at least one optical parameter (220, 220', ...) of the optical lens (112). In addition, at least two optical parameters (220, 220', ...) of the optical lens (112) can be determined as simultaneously as possible, so that changes which may occur between two individual measurements are not taken into account when evaluation of the measurement results, thereby accelerating the evaluation of the measurement results and achieving higher accuracy of the measurement results.
