METHOD FOR HELPING DETERMINE THE VISION PARAMETERS OF A SUBJECT

摘要

The invention concerns a method for helping determine the vision parameters of a subject (100), comprising the following steps: —taking (120) two images (11, 12) from two different angles of the face of the subject by means of a camera (10), the subject (S) being in a natural distant vision position, —determining (130) the inclination of the camera (10) relative to the ground at the time when the images are taken, —deducing therefrom (140) the inclination and the direction of the face of the subject (S), characterised in that the camera is arranged outside a foveal area of the subject when the images (11, 12) are taken (120).

1. A method for helping determine the vision parameters of a subject (100), including the following steps:
capture (120) two images (I1, I2) at two different angles of the subject's face by means of an image capturing device (10), the subject (S) being in a natural distant vision posture, determine (130) the inclination with respect to the ground of the image capturing device (10) at the time of image capture, deduce therefrom (140) the inclination and the cap angle value of the face of the subject (S), characterized in that the image capturing device is positioned outside a foveal area of the subject at the time of capture (120) of the images (I1, I2).
