摘要
A method of capturing a substantially front-view image of the face of a wearer wearing at least one frame (10), the image being captured by an image-capture appliance (1), and calculating the geometrico-physiognomic parameter (H, TETA) by processing the captured image. The calculation of the geometrico-physiognomic parameter (H, TETA) includes identifying in the image the image of a predetermined remarkable point (RC) that is directly or indirectly associated with the wearer's face or with the frame, and it takes into consideration a magnitude representative of the absolute vertical angle of observation (GAMMA) formed between firstly an observation line (DO) connecting the pupil (7) of the image-capture appliance (1) to the remarkable point (RC), and secondly its projection onto a horizontal plane (PF).
