METHOD OF MEASURING AT LEAST ONE GEOMETRIC/PHYSIOGNOMIC PARAMETER FOR FITTING THE FRAME OF VISION-CORRECTION SPECTACLES TO THE FACE OF A WEARER

摘要

The method comprises a step of capturing a substantially frontal digital image of the face of the wearer provided with at least the frame (10), by means of a camera (1), and a step of calculating the geometric/physiognomic parameter (H, THETA) based on the processing of the captured image. The calculation of the geometric/physiognomic parameter (H, THETA) comprises the identification, on this image, of the image of a predetermined noteworthy point (RC), directly or indirectly associated with the wearer's face or with the frame, and takes into consideration a quantity representative of the absolute vertical angle of observation (GAMMA) that makes a line of observation (DO), connecting the pupil (7) of the camera (1) to the noteworthy point (RC), with its projection on a horizontal plane (PF).
