<p>The method involves recording an image (12) of a face wearing a reference frame (50) at a scale, and processing the image displayed at the scale to determine a datum giving a vertical position of the reference frame on the face. An image of a virtual frame is superimposed on another image of the face using the datum such that the relative vertical position of the virtual frame and the vertical position of the reference frame correspond to each other exactly. Independent claims are also included for the following: (1) a system for on-line selection of a virtual eyeglass frame (2) a device for determining a vertical position of an eyeglass frame.</p> |
