Abstract
The invention relates to a method for measuring the geometric morphometric parameters of a person wearing glasses (21), said method implementing an independent computing device (1, 10) comprising a screen, a target (8, 18), a compact image acquisition system (7, 17) which is provided with a means of determining the inclination thereof, said system (7, 17) being connected to said screen, and a computer for controlling the image acquisition system (7, 17) and processing the images obtained. The main feature of a measuring method according to the invention is that it comprises a step in which the person observes the target (8, 18) placed in a position known to the image acquisition system (7, 17), by rolling his or her head in an upward direction while keeping his or her eyes fixed on the target (8, 18).
