Claim 11:
12. A system for estimating mass of one or more occupants in a vehicle cabin, said system comprising:
a sensing device comprising:
an illumination module comprising one or more illumination sources configured to illuminate said vehicle cabin;
at least one imaging sensor configured to capture a sequence of two-dimensional (2D) images and three-dimensional (3D) images of said vehicle cabin; and
at least one processor configured to:
apply a pose detection algorithm on each of the captured sequences of 2D images to yield one or more skeleton representations of said one or more occupants;
combine one or more of the 3D images of the sequence of 3D images with the one or more skeleton representations of said one or more occupants to yield at least one skeleton model for each one or more occupants, wherein the at least one skeleton model comprises information relating to a distance of one or more key-points in the at least one skeleton model from a viewpoint;
analyze the at least one skeleton model to extract one or more features of each of the one or more occupants; and
process the one or more extracted features of the at least one skeleton model to estimate said mass of each of said one or more occupants.
