Title
(EN) SYSTEM AND METHOD FOR VISUALISING ELEMENTS RELATING TO A PATIENT'S JOINT
(FR) SYSTÈME ET PROCÉDÉ DE VISUALISATION D'ÉLÉMENTS RELATIFS À UNE ARTICULATION D'UN PATIENT
Abstract
(EN)
The invention relates to an augmented reality visualisation system for presenting visual elements according to a spatial relationship between a first limb and a second limb joined by a joint, by: -determining, by means of a single locating device, a measurement of the spatial position of the locating device relative to an acquisition device, an angular measurement of the locating device relative to a vertical axis, and the spatial relationship between the limbs by considering the second limb as immobile, and, depending on the angular measurement of the locating device relative to the vertical axis, and a first hypothesis of positioning between the limbs; -presenting, on a display module, at least one visual representation of the limbs, depending on the spatial relationship between the limbs and the spatial position of the location device relative to the acquisition device.
(FR)
L'invention concerne un système de visualisation, en réalité augmentée, pour présenter des éléments visuels en fonction d'une relation spatiale entre un premier membre et un deuxième membre joints par une articulation, en: -déterminant, au moyen d'un unique dispositif de localisation, une mesure de la position spatiale du dispositif de localisation relativement à un dispositif d'acquisition,une mesure angulaire du dispositif de localisation relativement à un axe vertical, et la relation spatiale entre les membres en considérant le deuxième membre comme immobile, et en fonction de la mesure angulaire du dispositif de localisation relativement à l'axe vertical, et d'une première hypothèse de positionnement entre les membres; -présentant, sur un module afficheur, au moins une représentation visuelle des membres, en fonction de la relation spatiale entre les membres et de la position spatiale entre le dispositif de localisation relativement au dispositif d'acquisition.
