Embodiment Construction

[0106] figure 1 An exemplary embodiment of an apparatus for virtually fitting a pair of eyeglasses according to an exemplary embodiment is shown. figure 1 The apparatus comprises computing means 11 comprising a processor 12 and a memory 13. Memory 13 is used to store data, and in figure 1 In an exemplary embodiment, the memory includes random access memory (RAM), read only memory (ROM), and one or more mass storage media (hard disk, solid state disk, optical drive, etc.). A program is stored in the memory 13 for, when executed on the processor 12, implementing the method for virtually fitting a pair of spectacles as already described above or as will be explained in more detail below.

[0107] figure 1 The device further comprises a display 16 which, when the computer program is executed on the processor 12, displays the person's head together with the spectacle frames. For example, user input may be achieved through one or more input devices 17 (eg, keyboard and mouse...

Abstract

The invention relates to a method for virtual spectacle adjustment, a device and a computer readable recording medium. 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. According to the invention, defining the first measurement points comprises 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.

Description

[0001] This application is a patent application with an application date of July 3, 2018, an application number of 201880057588.0, an international application number of PCT / EP2018 / 067914, and an invention title of "Method, device and computer program for virtual fitting spectacle frames" divisional application. technical field [0002] The present application relates to methods, devices and computer programs for virtually fitting spectacle frames. Background technique [0003] Spectacle frames according to DIN ESO 77998:2006-01 and DIN ESO 8624:2015-12 are understood here to mean frames or holders on which spectacle lenses can be worn on the head. In particular, the term used herein also includes rimless spectacle frames. In layman's terms, spectacle frames are also called spectacle frames. Within the scope of this application, virtually putting on a spectacle frame means fitting a model of the spectacle frame to a model of the head on a computing device, usually on a dis...
