Title: METHOD, DEVICE AND COMPUTER PROGRAM FOR VIRTUALLY ADJUSTING A SPECTACLE FRAME
Abstract:
Disclosed are methods, computer programs and devices for a virtual try-on process for spectacles, using approximate- and precise adjustment. Provided for this purpose are 3D models of a head and a spectacle frame and head metadata based on the model of the head and frame metadata based on the model of the frame. The head metadata comprises placement information, in particular a placement point, which can be used for the approximate positioning of the spectacle frame on the head, and/or a placement region which describes a region of the arm of the frame for placement on the ears of the head. A rapid and relatively simple computational positioning of the spectacle frame on the head and a more accurate positioning using a subsequent precise adjustment can be achieved with the aid of metadata of this type.
