The invention concerns a method for estimating an eye-glasses distance (VG) comprising steps of: a) acquiring at least two images of the wearer (1), on which the head (10) of the wearer has different angular positions, and b) determining, for each acquired image, a tilt angle (α301) of the head of the wearer relative to the image sensor. According to the invention, the following steps are also included: c) acquiring at least two simulated values (VG1, VG2, VG3) of the eye-glasses distance being researched, d) calculating, for each acquired image 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, taking said tilt angle into consideration, and e) selecting, from the simulated values, that which is closest to the eye-glasses distance of the wearer, on the basis of the head-plane distances calculated in step d). |
