The invention relates to a method for constructing a model of the face of a person which comprises the following steps: locating (L), by means of an acquisition apparatus and at each time of a plurality of acquisition times, a single plurality of characteristic points of said face of the person such as to form a corresponding plurality of specific models of said face of the person each including the positions of said characteristic points of the face of the person at the time associated with the specific model in question; adjusting (A) by determining, for each specific model of said face of the person, a model adjusted relative to a reference model of said face of the person, the adjusted model being obtained in accordance with the specific model in question such that the distance between the adjusted model and the reference model is minimal according to a given metric; and constructing (C), from the adjusted models obtained during the adjustment step (A), said model of the face of the person. The invention also proposes methods and devices for posture analysis using such a constructed model. |
