    摘要： A method of measuring morpho-geometrical parameters of a person wearing eyeglasses includes causing the person to observe a point situated in front at infinity while holding the head naturally on a direction (24) that is substantially horizontal, acquiring a first image of the position of the frame (21) in this first posture, causing the person to observe the target (8, 18) placed in a known position relative to the image acquisition system, by adopting a position that is natural and comfortable and that involves at least a tilting movement of the head; acquiring a second image of the position of the frame (21) in this second posture, determining the positions of the eyes (27) from one of the two images, computer processing of the two images obtained in order to determine the morpho-geometrical parameters of the person, and delivering the results of the measurements.

    摘要： The invention relates to a method for determining the position of a target drill hole (210; 250) to be formed on a target correction lens (200) having a target outline (220) after trimming and from a reference lens (100) having reference outline (120) and at least one reference drill hole (110; 150), said method comprising the following steps: acquiring an image of the reference lens (100); acquiring at least one characteristic of the curve (ALPHA100; ALPHA150) of the reference lens (100); determining, in the acquisition plane (P1; P2), the distance in a reference projection (R1; R4) between the projection (MO1; MC1 ) of a reference anchoring point (O1; C1) of the reference lens (100) and the projection (MC1; MC5) of a reference drill point (C1; C5) of the referent drill hole (110; 150); calculating the reference three-dimensional distance (R2; R5) between the reference anchoring point (O1; C1) and the reference drill point (C1; C5) based on said characteristic of the curve (ALPHA100; ALPHA150) of the reference lens (100) and on the determined distance in a reference projection (R1; R4); determining the position of the target drill point (C10; C15) of the target drill hole (210; 250) o the target correction lens (200) based on the calculated reference three-dimensional distance (R2; R5).

    摘要： The invention relates to a method for measuring a distance (D) separating a camera (CAM) from a reference object (12) comprising a predetermined number of corners (20) arranged in a pattern and at least two reference points (P1, P2) separated by a reference length (L). The method comprises steps of:
    - acquiring an image comprising the reference object with the camera,
    - detecting corners in the image,
    - attributing a class (+X, +Y, -X, -Y) to each corner, based on an orientation of the corner,
    - detecting the reference object in the image based on the corners and attributed classes,
    - placing the reference points in the image based on the corners of the reference object and measuring an imaged length separating the reference points, and
    - comparing the reference length to the imaged length and obtaining the distance separating the camera from the reference object.
