Abstract
A method of measuring morpho-geometrical parameters of a person wearing eyeglasses includes causing the person to observe a point situated in front at infinity while holding the head naturally on a direction () that is substantially horizontal, acquiring a first image of the position of the frame () in this first posture, causing the person to observe the target () placed in a known position relative to the image acquisition system, by adopting a position that is natural and comfortable and that involves at least a tilting movement of the head; acquiring a second image of the position of the frame () in this second posture, determining the positions of the eyes () from one of the two images, computer processing of the two images obtained in order to determine the morpho-geometrical parameters of the person, and delivering the results of the measurements.
