Title
(EN) SYSTEMS AND METHODS FOR ANATOMY-CONSTRAINED GAZE ESTIMATION
(FR) SYSTÈMES ET PROCÉDÉS D'ESTIMATION D'UN REGARD LIMITÉ PAR L'ANATOMIE
Abstract
(EN)
The disclosure relates to systems, methods and programs for anatomically-constrained gaze estimation. More specifically, the disclosure is directed to systems, methods and programs for providing a point of reference (PoR) in a 3D field and/or 2D plane, based on 6 DOF head pose constrained by the eyeball center being fixed in a common 3D coordinate system.
(FR)
La présente invention concerne de manière générale des systèmes, des procédés et des programmes d'estimation d'un regard limité anatomiquement. Plus spécifiquement, l'invention concerne des systèmes, des procédés et des programmes de fourniture d'un point de référence (PoR) dans un champ 3D et/ou un plan 2D, sur la base d'une pose de tête 6 DOF limitée par le centre du globe oculaire qui est fixé dans un système de coordonnées 3D commun.
