摘要:
A method for estimating an eye/spectacles distance (VG) includes the steps of: a) acquiring at least two images of the wearer (1), in which the head (10) of the wearer exhibits various angular positions b) determining, for each image acquired, an angle of inclination (&alpha301) of the head of the wearer with respect to the image sensor c) acquiring at least two simulated values (VG1, VG2, VG3) of the eye/spectacles distance sought d) calculating, for each image acquired and with each simulated value, a morphological distance (EG1301, EG2301, EG3301) between the eye of the wearer and a median plane of the head of the wearer, having regard to the angle of inclination and e) selecting, from among the simulated values, the one closest to the eye/spectacles distance of the wearer, as a function of the head/plane distances calculated in step d).
