Abstract

La présente invention comprend les étapes consistant à : obtenir une photo de référence et une pluralité de photos en proche infrarouge par capture du visage d'un sujet à mesurer par l'intermédiaire d'une caméra proche infrarouge incluse dans un appareil de mesure de sinus tandis que le sujet à mesurer porte un embout buccal pour une émission orale dans la bouche ; mesurer la pente de la photo de référence à partir du visage du sujet à mesurer capturé dans la photo de référence ; corriger horizontalement la pluralité de photos en proche infrarouge par rotation de la pluralité de photos en proche infrarouge par l'amplitude de la pente mesurée ; calculer un indice d'évaluation pour la posture du sujet à mesurer à l'aide de chacune de la pluralité de photos en proche infrarouge ; sélectionner une ou plusieurs photos en proche infrarouge ayant une valeur de pixel à un premier point dans une certaine plage, et sélectionner une photo en proche infrarouge ayant la plus grande valeur de pixel parmi la ou les photos en proche infrarouge sélectionnées ; et calculer chacun des indices de sinus gauche et droit pour la photo en proche infrarouge sélectionnée.
