More Information
Summary:The invention relates to a method for determining a position, particularly a coronal position of an eye (10) relative to a coronal plane (15) of the head (10) of a person, with a handheld 3D-surface scanning device, the method comprising the steps of : Acquiring a digital data set comprising information about a three- dimensional surface and texture of at least a portion of the face of the person, the portion of the face comprising both eyes (10); Determining from the data set for each eye (10) a three-dimensional center position (10-1, 10-2) of the center of the pupil of the eye (10); Determining from the data set for each eye (10) a three-dimensional rim position (11-, 11-2) that corresponds to the anterior lateral orbital rim of the eye (10); Determining a connecting line (11-3) between the two rim positions (11-1, 11-2); Determining for each center of the pupils (10-1, 10-2) a distance to the connecting line (11-3), said distances corresponding to the coronal position of each eye (10) relative to the coronal plane (15) of the head (1).
