Abstract[English]
The present invention relates to a method for determining information concerning quantities relating to a face captured by at least one camera, comprising - detecting at least one face in at least one image captured by the at least one camera - adjusting a model of a reference face on which key points are located, based on an estimate of a morphological typing of the detected face; - on the detected face, localizing key points corresponding to at least a first subset of the key points of the reference face, and obtaining the location, relative to the camera, of the at least one detected face relative to the at least one camera in a length measurement system, said location being obtained based on a focal length of the camera, pixel coordinates of at least a second subset of the key points located on the at least one detected face, and coordinates in the length measurement system of the key points of the first subset located on the adjusted modelled reference face.[French]
La présente invention concerne un procédé de détermination d'informations de grandeurs relatives à un visage capturé par au moins une caméra comprenant - une détection d'au moins un visage dans au moins une image capturée par ladite au moins une caméra - un ajustement d'une modélisation d'un visage de référence, sur lequel sont localisés des points-clés, à partir d'une estimation d'un typage morphologique dudit visage détecté; - une localisation, sur ledit visage détecté, de points-clés correspondant à au moins un premier sous-ensemble desdits points-clés dudit visage de référence et, - une obtention d'une localisation par rapport à la caméra, dans un système de mesure de longueur, dudit au moins un visage détecté par rapport à ladite au moins une caméra, ladite localisation étant obtenue à partir d'une distance focale de ladite caméra, des coordonnées en pixels d'au moins un second sous-ensemble desdits points-clés localisés sur ledit au moins un visage détecté, des coordonnées dans ledit système de mesure de longueur des points-clés dudit premier sous-ensemble localisés sur ledit visage de référence modélisé ajusté.
