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 |
<p>Method includes: (a) placing on a user's head an accessory including at least one brightness calibration element having at least two contrasted zones; (b) capturing an image of the user's head with the accessory thereon with a device; (c) determining the position of the image of the brightness calibration element of the accessory on the captured image; (d) determining a measured value of the brightness of one part of the image of the brightness calibration element or of the image located close to the brightness calibration element; (e) modifying a parameter for adjusting the optical image-acquisition conditions of the device as a function of the measured value to improve the contrast of the image of contrasted zones of the calibration element; (f) capturing another image with the modified parameter for adjusting the optical acquisition conditions; and (g) determining the required geometric/physiognomic mounting parameter on the basis of the other image.</p> |
