/ METHOD FOR DETERMINING AT LEAST ONE GEOMETRIC/PHYSIOGNOMIC PARAMETER ASSOCIATED WITH THE MOUNTING OF AN OPHTHALMIC LENS IN A SPECTACLE FRAME WORN BY A USER

摘要

The present invention provides a method comprising the steps of: a) placing an accessory on a user's head, said accessory comprising at least one brightness correction element comprising at least two contrasting areas; b) capturing an image of a user's head where the accessory is located using an image capture device; c) determining the position of the image of the luminance correction component of the accessory on the image captured in step b); d) determining a measured value of luminance of at least a portion of the image of the luminance correction element or of at least a portion of the image located proximate to the luminance correction element; e) modifying a parameter for adjusting an optical image acquisition condition of the image capture device in accordance with the measurement value to improve the contrast of the image of the contrasting area of the correction element; f) capturing another image with a modified parameter for adjusting the optical image acquisition condition; And g) determining a desired geometric / impressive mounting parameter based on the other image.
