摘要：
The present invention relates in general to taking geometrico-morphological measurements on a subject. More particularly, the invention relates to a method of measuring the position of a remarkable point of the subject's eye. The method includes amongst others, the steps of capturing images in different relative postures (APIV1, APIV2, (O1,X1,Y1,Z1), (O2,X2,Y2,Z2)) of a subject, identifying reference points of the eye ((RCG1, RCD1), (RCG2, RCD2)), and calculating the remarkable point (CROD, CROG) as a function of the captured images. The values of the posture parameter (APIV) are obtained by a position-identification element (60, 70, 80, 700, 800) having at least one known geometrical characteristic that is placed on the subject's head. Each captured image contains a representation of the position-identification element (60, 70, 80, 700, 800). The posture parameter is thus calculated as a function of these images and of the known geometrical characteristic.
