Abstract

A method for the on-line selection of virtual eyeglass frames, of the type in which the virtual frame is an image designed to be superimposed on a first image of a face, is provided wherein the images being recorded at the same scale as each other in order to be displayed simultaneously in such a way as to produce a representation of the face wearing the virtual frame. The method includes the steps of a second image of the face wearing a reference frame is recorded, the second image displayed at the scale is processed to determine a datum giving the vertical position of the reference frame on the face, and the image of the virtual frame is superimposed on the first image of the face using the datum, so that the relative vertical positions of the virtual frame and the face on the one hand, and of the reference frame and the face on the other, correspond exactly.

Dependent claims

Method for the on-line selection of a virtual eyeglass frame from among a plurality of virtual frames, said method comprising:

generating an image giving a representation of a face wearing a selected virtual eyeglass frame, said image being constituted by superimposition of an image of said virtual eyeglass frame and a first image of a face without a frame recorded at the same scale as each other in order to be displayed simultaneously on a screen in such a way as to produce a representation of said face wearing the virtual eyeglass frame;
recording a second image of said face wearing a reference frame at said scale;
processing said second image displayed at said scale to determine a datum giving a vertical position of said reference frame on said face;
adjusting the position of said image of said virtual frame relative to said first image of said face according to said datum determined from said second image of said face;
and
wherein processing said second displayed image comprises drawing a horizontal line passing approximately through a center of the eyes of said face, projecting horizontally onto a plane of said second image a reference element of predefined length displayed at said scale, between two parts of said reference frame which fit over a nose of said face, which parts are separated by said predefined length, and measuring in the plane of said second image a distance between said horizontal line and said reference element of predefined length, said measured distance forming said datum.

System for the selection of a virtual eyeglass frame, comprising:

image capture means for providing a first image of a face and a second image of said face wearing a reference frame;
first processing means connected to said image capture means for formatting said first and second images to a single scale;
said first processing means being configured to determine, from said second formatted image, a datum for a vertical position of said reference frame on said face;
first storage means for storing said first formatted image and information about said face including at least said datum;
second storage means for storing a plurality of virtual eyeglass frame images at said scale;
and second processing means for positioning a selected virtual eyeglass frame image virtually on said face, by superimposing the selected virtual eyeglass frame image on said first image of said face using said datum so that relative vertical positions of said selected virtual eyeglass frame image and said face and of said reference frame and said face correspond exactly.
