摘要： A method of determining at least one behavioral parameter of a wearer for designing an ophthalmic eyeglass lens includes: a) acquiring a first data set from a first representation of the head of the wearer in three dimensions; b) determining the relative position in space of at least three particular points of the head based on the data set; c) acquiring a second data set from a second representation of the head in a natural posture, including at least one image of each of the three particular points; d) identifying the image of each of the particular points from step b) on the representation of step c); e) deducing information relating to the position and/or to the orientation of the head of the wearer during the determination of the second representation from this identification; and f) determining the behavioural parameter of the wearer based on the information from step e).

摘要： Disclosed is a method for constructing a model of a face, including: locating (L) a single plurality of characteristic points of the face, forming a corresponding plurality of specific models of the face each including the positions of the 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 the face, a model adjusted relative to a reference model of the 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), the model of the face of the person. Also disclosed are methods and devices for posture analysis using such a constructed model.

摘要： Disclosed is a method of determining at least one visual behavior parameter of an individual, including: determination of the position of the center of rotation of at least one eye of the individual in a first reference frame tied to the head of the individual; capture, with the aid of an image capture device, of at least one image of at least one part of the body of the individual in a second reference frame, determination of the position and the orientation, in the second reference frame, of the first reference frame tied to the head of the individual, by searching for the position, in the second reference frame of a distinctive zone of the part of the body of the individual; determination of the position of the center of rotation of the eye in the second reference frame; and determination of the sought-after visual behavior parameter.
