Abstract

La présente invention a trait à des lunettes AR ainsi qu'à un système de suivi associé. Les lunettes AR comprennent un corps de lunettes AR (1) et une pluralité d'éléments de marquage (2). Les éléments de marquage (2) se trouvent sur le corps de lunettes AR (1) et se situent dans un plan horizontal. La distance entre deux éléments de marquage (2) n'est pas toujours la même. Ces éléments de marquage (2) servent à renvoyer vers l'extérieur des signaux représentant des informations de localisation. Grâce à la disposition desdits éléments de marquage (2) sur le corps de lunettes AR (1) pour obtenir des informations de localisation des lunettes AR en temps réel, et grâce à l'intégration des informations de localisation dans une image tridimensionnelle chirurgicale entière, lorsqu'un médecin porte ces lunettes AR, avec le mouvement de sa tête, une image virtuelle affichée sur lesdites lunettes AR peut être superposée avec précision à un site chirurgical réel d'un patient dans l'environnement véritable, afin d'offrir une meilleure aide lors d'une chirurgie.
