摘要：
Method includes: (a) placing on a users head an accessory including at least one brightness calibration element having at least two contrasted zones (b) capturing an image of the users 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.
