Method for determining at least one geometric postural parameter when fitting a corrective spectacle frame on the face of a wearer in the anatomical posture thereof
A method includes:a) defining position-identification elements for identifying the position of a first frame of reference associated with a wearers head in a second frame of reference associated with an image-capture device and for identifying the angle of inclination of the first frame of reference in the sagittal plane of the wearers head about a center of rotation of the headb) capturing a series of at least two images of the wearers headc) determining, in the second frame of reference, a position of the center of rotationd) identifying, in each image, the image of a first anatomical point of the wearers facee) determining, in each image, the angle of inclination relative to a reference plane of an anatomical plane that is perpendicular to the sagittal plane and that contains the center of rotation and the first anatomical pointf) comparing the angle with a predetermined value andg) determining the geometrical-and-postural parameter as a function of the comparison.
