Method allowing an individual to realistically try on a pair of spectacles virtually

Method for generating a final image of an individual from an initial image of the individual acquired by a real camera, the image being a still or contained in a video stream, recorded or in real time, said method comprising steps of:

• a) detecting the face of the individual in the initial image;
• b) realistically positioning a virtual frame on the face of the individual detected in the initial image, the frame comprising at least one ophthalmic lens characterized by an optical correction and/or an optical treatment;
• c) calculating a representation of the scene perceived from the virtual camera through the ophthalmic lens or lenses according to the refraction of the ophthalmic lens or lenses and of a depth map of the initial image;
• d) generating an overlay that is superimposed on the initial image, the overlay comprising a representation of the scene calculated in the step c);
• e) generating the final image by merging the overlay generated in step d) with the initial image.
