  • Patent number: 11262597
    Abstract: A virtual try-on process for spectacles includes an approximate positioning and a fine positioning of a spectacle frame on a head of a user. Provided for this purpose are 3D models of the head and the spectacle frame, as well as head metadata based on the model of the head and frame metadata based on the model of the frame. The head metadata contains 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 earpiece part 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 the metadata.

  • Publication number: 20200233239
    Abstract: A method for virtual spectacle adjustment and a corresponding computer program and computing device are disclosed. First measurement points are defined on a 3D model of a person's head, and a model of a frame is adjusted on the basis of the first measurement points. Defining the first measurement points includes defining second measurement points on a parametric head model, adjusting the parametric head model to the 3D model of the person's head, and determining the first measurement points on the basis of the second measurement points and the adjustment. In this way, the second measurement points only have to be defined once on the parametric model so that the first measurement points can be defined for a plurality of different 3D models of different heads.
