Abstract

Habitacle de véhicule comprenant un dispositif pour estimer une masse et/ou une taille d’au moins une partie du corps d’un passager et procédé s associé s L’invention concerne un habitacle (12) de véhicule (10) comprenant un dispositif (20) pour estimer une masse et/ou une taille d’au moins une partie du corps d’un passager (14) à l’intérieur du véhicule (10), le dispositif (20) comprenant : - un dispositif d’imagerie (22) pour acquérir au moins une image tridimensionnelle d’une partie du corps du passager (14) dans le véhicule, - au moins une unité de calcul (28) pour calculer : la masse de la partie du corps du passager (14) à partir d’un volume de la partie du corps du passager (14) et d’une densité moyenne associée à ladite partie du corps du passager (14), ledit volume étant calculé à partir de l’image tridimensionnelle de ladite partie du corps, et/ou la taille de la partie du corps du passager (14) à partir de l’image tridimensionnelle. Figure pour l'abrégé : Figure 1Vehicle interior comprising a device for estimating a mass and/or size of at least one part of a passenger's body and associated method s The invention relates to a vehicle interior (12) (10) comprising a device ( 20) for estimating a mass and/or a size of at least a part of the body of a passenger (14) inside the vehicle (10), the device (20) comprising: - an imaging device ( 22) for acquiring at least one three-dimensional image of a part of the passenger's body (14) in the vehicle, - at least one calculating unit (28) for calculating: the mass of the part of the passenger's body (14) at from a volume of the passenger's body part (14) and an average density associated with said passenger's body part (14), said volume being calculated from the three-dimensional image of said body part, and/or the size of the passenger's body part (14) from the three-dimensional image.
