METHOD OF DETERMINING AT LEAST ONE BEHAVIOURAL PARAMETER

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).

1. A method for determining at least one behavioral parameter of a wearer with a view to designing an ophthalmic lens for a spectacle frame of this wearer, including the following steps:
a) acquiring a first dataset corresponding to a first representation of the head of the wearer in three dimensions, b) determining, from this dataset, the relative position in space of at least three particular points of the head of the wearer, c) acquiring a second dataset corresponding to a second representation of the head of the wearer in a natural posture, comprising at least one image of each of the three particular points of the head of the wearer, d) identifying, in said second representation of step c), the image of each of said particular points of the head of the wearer the relative positions in space of which were determined in step b), e) deducing from this identification information relating to the position and/or orientation of the head of the wearer during the determination of said second representation, f) determining, from the information deduced in step e), said behavioral parameter of the wearer.
