摘要:
The invention relates to a method of measuring morpho-geometrical parameters of a person wearing eyeglasses (21), fitted with position-identification means (22), the method making use of an independent computer device (1, 10) comprising a screen, a target (8, 18), a compact image acquisition system (7, 17) having means for determining its angle of inclination, and a computer. The main characteristic of a method of the invention is that it comprises the following steps: causing the person to observe a point situated in front at infinity while holding the head naturally on a direction (24) that is substantially horizontal; · acquiring a first image of the position of the frame (21) in this first posture; causing the person to observe the target (8, 18) 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 (21) in this second posture; determining the positions of the eyes (27) 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.
