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.
