Method of measuring at least one geometrico-physionomic parameter for positioning a frame of vision-correcting eyeglasses on the face of a wearer
First Claim
1. A method of measuring at least one geometrico-physionomic parameter (H, TETA) concerning the positioning on the face of a wearer of a frame (10) for vision-correcting eyeglasses, the method comprising capturing at least one digital image of the wearer'"'"'s face wearing the frame (10) by using an image sensor such as an image capture appliance (1;

Abstract
The method includes capturing at least one digital image of the wearer'"'"'s face with a portable image capture appliance (1) and processing the captured image to determine a geometrico-physionomic parameter. Before capturing the image, the operator positions the image capture appliance manually in a first configuration in which an observation line connecting the pupil (7) of the image capture appliance with a predetermined remarkable point associated with the wearer'"'"'s face or with the frame is substantially horizontal. Image capture is performed in a second configuration of the image capture appliance such that the altitude of the image capture appliance is identical to its altitude in the first configuration. The calculation of the geometrico-physionomic parameter includes identifying on the image, the image of the predetermined remarkable point.
