Abstract
A method for automatically determining at least one parameter associated with an ophthalmic device selected by an individual, said device comprising a frame referred to as selected frame, said determination being carried out from an acquired image of the face of the individual wearing the selected frame or a frame of a second ophthalmic device. The method includes the steps of: detecting at least one characteristic point of at least one eye of the individual the acquired image and estimating the three-dimensional position of the one or more characteristic point(s) detected; detecting the frame worn and estimating the three-dimensional position of the frame worn by aligning a three-dimensional representation of the frame worn with the frame worn in the acquired image; and determining the one or more parameters from the relative position of the eyes with respect to the three-dimensional representation of the selected frame.
