摘要

Procedure for measuring at least one geometric-physiognomic parameter (H, TETA) of implanting a frame (10) of glasses for visual correction on the face of a user with a view to the assembly and / or custom calculation of the corrective lenses associated with this mount, which includes an operation to capture a substantially frontal digital image of the user's face equipped with at least the mount (10), by means of an image capture apparatus (1), and a parameter calculation operation geometric-physiognomic (H, TETA) from a treatment of the captured image, characterized in that the calculation of the geometrical-physiognomic parameter (H, TETA) includes an identification on this image, of the image of a predetermined remarkable point (RC ), directly or indirectly associated with the user's face or the mount, and takes into consideration a representative magnitude of the absolute vertical observation angle (GAMMA) that forms an observation line tion (OD), which joins the pupil (7) of the image capture apparatus (1) and the remarkable point (RC), with its projection on a horizontal plane (PF).
