A method for determining a value of at least one geometrico-morphological parameter of a subject wearing an eyewear. The method including obtaining at least one image of a head of the subject wearing the eyewear, identifying simultaneously, on the at least one image obtained, a set of remarkable points of the image of the eyewear and a set of remarkable points of the image of the head of the subject, using an image processing algorithm determined based on a predetermined database comprising a plurality of reference images of heads wearing an eyewear, the image processing algorithm being based on machine learning, and determining at least one value of a geometrico-morphological parameter taking into account the sets of remarkable points of the image of the eyewear and head of the subject identified.

Geometrico-morphological parameter of a subject wearing an eyewear

A method for determining a pupillary distance of an individual, includes the following steps: &#x2014;displaying an object on a screen located in front of the individual, the displayed object being positioned at a location in front of one eye of the individual; &#x2014;instructing the individual to look with at least the eye at the displayed object; &#x2014;acquiring at least an image of a part of the body of the individual including the eye; &#x2014;determining the location of a plurality of specific features in the acquired image, one of the specific features being a pupil of the eye of the individual; and &#x2014;calculating the pupillary distance based on the location of the plurality of specific features. A corresponding system is also described.
