Technique antérieure Prior art
On connaît, dans le domaine de la lunetterie, différents procédés et appareils destinés à déterminer les paramètres physiologiques d'un patient en regard d'une monture de lunettes. Certains de ces appareils permettent d'assurer l'enregistrement automatique des mesures au moyen d'une caméra et à la détermination des mesures appropriées résultantes à l'aide de moyens de traitement des images obtenues. Les mesures effectuées permettent ensuite à un opticien de fabriquer des verres correcteurs en fonction du patient . There are known, in the field of eyewear, various methods and apparatus for determining the physiological parameters of a patient in relation to a spectacle frame. Some of these devices make it possible to ensure the automatic recording of the measurements by means of a camera and to the determination of the appropriate measures resulting from this by means of processing the images obtained. The measurements made then allow an optician to manufacture corrective lenses depending on the patient.
Les dispositifs les plus perfectionnés permettent également de mesurer les paramètres physiologiques de l'œil par rapport à une monture dans le cas de verres correcteurs permettant une vision de loin et une vision de près. Ils permettent également de mesurer d'une part la distance existant entre la partie frontale de chacun des globes oculaires du patient et la face interne de chaque verre de lunettes et d'autre part le bon positionnement angulaire des verres par rapport à la verticale. The most advanced devices also make it possible to measure the physiological parameters of the eye with respect to a frame in the case of corrective lenses allowing distant vision and near vision. They also make it possible to measure, on the one hand, the distance between the front part of each of the patient's eyeballs and the inner face of each glass of glasses and secondly the good angular positioning of the glasses relative to the vertical.

L'invention a également pour but de proposer un procédé comprenant l'utilisation dudit dispositif. L'invention a également pour but de proposer un procédé pour modifier les dispositifs de mesure de l'art antérieur pour les adapter aux verres teintés. Résumé de l'invention The object of the invention is to overcome the drawbacks of the prior art and to propose a device making it possible to measure the physiological parameters of the eye of a wearer of tinted lenses.

Description des modes de réalisation Description of the embodiments
On décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence aux dessins annexés.  An embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the accompanying drawings.
En figure 1 est présenté un patient portant une paire de lunettes 1 sur laquelle est placée un élément positionneur 2. L'élément positionneur comporte un pont 3 sensiblement horizontal dont les extrémités sont chacune pourvues d'une première branche contre laquelle la face antérieure d'un verre correcteur 4 vient en appui et une deuxième branche qui s'appuie sur la face postérieure du verre correcteur 4. L'élément positionneur comporte au moins un repère 5.  FIG. 1 shows a patient wearing a pair of spectacles 1 on which a positioner element 2 is placed. The positioner element comprises a substantially horizontal bridge 3 whose ends are each provided with a first branch against which the anterior face of FIG. a corrective glass 4 comes into abutment and a second arm resting on the rear surface of the corrective glass 4. The positioning element comprises at least one mark 5.
Dans le cadre de la présente invention, les verres correcteurs 4 sont teintés.  In the context of the present invention, corrective lenses 4 are tinted.
Le dispositif selon l'invention 6 comprend un moyen de saisie 7, par exemple une caméra ou un appareil photo monté sur une colonne 8 formant un moyen de déplacement ajustable en hauteur. Pour déterminer l'orientation du repère 5 de l'élément positionneur 2 lors de la vision de loin, le dispositif comporte un élément de référence visuelle pour le patient. Cet élément de référence visuelle est par exemple placé juste au-dessus ou juste au-dessous du moyen de saisie 7. Il pourrait aussi être de type annulaire encerclant la lentille du moyen de saisie 7. Il n'est pas nécessairement à proximité du moyen de saisie 7 mais pourrait, par exemple, être fixé à un mur se trouvant derrière le moyen de saisie 7. The device according to the invention 6 comprises an input means 7, for example a camera or a camera mounted on a column 8 forming a means of displacement adjustable in height. To determine the orientation of the marker 5 of the positioner element 2 during far vision, the device comprises a visual reference element for the patient. This visual reference element is for example placed just above or just below the gripping means 7. It could also be of the annular type encircling the lens of the gripping means 7. It is not necessarily close to the means 7 but could, for example, be attached to a wall behind the gripping means 7.
Avantageusement, ledit élément de référence visuelle se confond avec la source de rayonnement apte à irradier ladite cornée dudit patient. On peut ainsi envisager un moyen apte à émettre de la lumière visible, servant de référence visuelle, et également apte à émettre un rayonnement infrarouge de courte durée (de type flash) . L'exposition au rayonnement infrarouge est avantageusement limitée à la durée de la prise d'image.  Advantageously, said visual reference element merges with the radiation source capable of irradiating said cornea of said patient. It is thus possible to envisage a means capable of emitting visible light, serving as a visual reference, and also capable of emitting short-lived infrared radiation (of the flash type). Exposure to infrared radiation is advantageously limited to the duration of the image.
Le dispositif 6 comprend en outre un moyen de traitement d'image, avantageusement sous la forme d'un logiciel qui va être apte à calculer les différents paramètres physiologiques de l'œil du patient. Ce calcul utilise les repères 5 de l'élément positionneur 2 comme référence. La distance entre ces différents repères 5 étant préalablement connue, le moyen de traitement d'image peut calculer les différents paramètres comme l'écart pupillaire, la hauteur pupillaire, l'angle pantoscopique, l'écart de vision de près et la distance verre/œil à partir de la position du reflet de la source de rayonnement à la surface de la cornée du patient.  The device 6 further comprises an image processing means, advantageously in the form of software that will be able to calculate the various physiological parameters of the patient's eye. This calculation uses the markers 5 of the positioner element 2 as a reference. The distance between these different marks 5 being previously known, the image processing means can calculate the various parameters such as the pupillary distance, the pupil height, the pantoscopic angle, the near vision deviation and the distance between the lens and the lens. eye from the position of the reflection of the radiation source on the surface of the patient's cornea.
Le dispositif 6 peut cumuler plusieurs moyens de saisie 7 capables de saisir le rayonnement infrarouge et/ou la lumière visible en fonction des besoins. Ce mode de réalisation permet au dispositif de traiter indifféremment les porteurs de verres transparents et les porteurs de verres teintés. The device 6 can accumulate several input means 7 capable of capturing the infrared radiation and / or visible light as needed. This embodiment allows the device to treat indifferently carriers of transparent glasses and tinted glass carriers.
Le dispositif 6 selon l'invention peut également comprendre un moyen d'affichage (e.g. un écran LCD) avantageusement placé au dos de la colonne permettant à l'opticien de visualiser la prise de vue et le résultat des calculs. Ce moyen d'affichage est préférentiellement un écran tactile qui permet à l'utilisateur d' interagir avec le dispositif 6 selon l'invention.  The device 6 according to the invention may also comprise a display means (e.g. an LCD) advantageously placed on the back of the column allowing the optician to view the shooting and the result of the calculations. This display means is preferably a touch screen that allows the user to interact with the device 6 according to the invention.
Le dispositif 6 selon l'invention peut également comprendre un moyen d' impression et/ ou un moyen de stockage de l'information permettant de stocker les images saisies et les paramètres mesurés.  The device 6 according to the invention may also comprise printing means and / or information storage means for storing the captured images and the measured parameters.
Comme indiqué à la figure 2, le patient porteur de verres teintés 2 et de l'élément positionneur 3 va se placer face au dispositif 6 selon l'invention. Le moyen de saisie 7 va être déplacé de façon à se placer à la hauteur des yeux du patient. Le patient va fixer la référence visuelle, puis le dispositif 6 va déclencher le rayonnement infrarouge et la saisie de l'image du visage du patient.  As indicated in FIG. 2, the patient carrying tinted lenses 2 and the positioner element 3 will face the device 6 according to the invention. The grasping means 7 will be moved so as to be at eye level of the patient. The patient will set the visual reference, then the device 6 will trigger infrared radiation and capture of the image of the patient's face.
L'opticien va pouvoir contrôler, grâce au moyen d'affichage, la qualité de l'image saisie, la présence des reflets cornéens et le repérage des différents repères 5. Si besoin, la position des repères 5 et des reflets cornéens peut être corrigée par l'opticien via l'écran tactile .  The optician will be able to control, thanks to the display means, the quality of the image captured, the presence of corneal reflections and the marking of the different markers 5. If necessary, the position of the markers 5 and corneal reflections can be corrected by the optician via the touch screen.
Une fois l'image saisie validée, l'opticien va pouvoir déclencher la phase de calcul des paramètres physiologiques de l'œil du patient, les stocker en mémoire et/ou les imprimer. Alternativement le dispositif 6 selon l'invention peut être portatif (voir figure 3 et 4) et se présenter sous la forme d'une tablette tactile 9 ou d'un ordiphone, comprenant un moyen de saisie 7 et une source de rayonnement infrarouge 10 placés sur la face avant (figure 3) et/ou sur la face arrière (figure 4) de ladite tablette tactile 9. Once the captured image is validated, the optician will be able to trigger the phase of calculating the physiological parameters of the patient's eye, store them in memory and / or print them. Alternatively, the device 6 according to the invention can be portable (see FIG. 3 and 4) and be in the form of a touch pad 9 or an ordi phone, comprising an input means 7 and an infrared radiation source 10 placed on the front face (FIG. 3) and / or on the rear face (FIG. 4) of said touch pad 9.
Ce dispositif 6 peut être aisément obtenu en modifiant les tablettes tactiles disponibles commercialement. Cette modification peut notamment consister à enlever le filtre infrarouge placé devant les capteurs du moyen de saisie 7 et à ajouter une source de rayonnement supplémentaire 10. Cette source de rayonnement 10 peut être avantageusement celle décrite dans la demande FR2993997 (modifiée pour émettre dans l'infrarouge). On peut également envisager de coupler les tablettes tactiles (incluant les ordiphones) actuellement disponibles avec un moyen de saisie externe. Ce moyen de saisie externe peut être relié au reste du dispositif via une liaison filaire ou non filaire (par exemple les caméras wifi) .  This device 6 can be easily obtained by modifying commercially available touch pads. This modification may notably consist in removing the infrared filter placed in front of the sensors of the gripping means 7 and in adding an additional radiation source 10. This radiation source 10 may advantageously be that described in patent application FR2993997 (modified to transmit in FIG. infrared). One can also consider coupling the touch pads (including the devices) currently available with an external input means. This external input means can be connected to the rest of the device via a wired or non-wired connection (for example the wifi cameras).
Le positionnement sur la façade avant ou sur la façade arrière des moyens de saisies et de la source de rayonnement dépend de l'utilisation souhaitée. Une disposition sur la façade avant permet une manipulation par le patient qui maintient le dispositif 6 entre ses mains. Un positionnement sur la façade arrière permet une utilisation par l'opticien qui va tendre le dispositif 6 en direction du patient.  Positioning on the front or rear facade of the input means and the radiation source depends on the desired use. An arrangement on the front panel allows manipulation by the patient who holds the device 6 in his hands. A positioning on the back cover allows use by the optician who will stretch the device 6 towards the patient.
