Problems solved by technology

[0017] In general, the problem with the approach described in this document, as well as in the other aforementioned documents, is that manufacturers often specify certain fit guidelines for fitting spectacle frames that primarily define the aesthetics of the frame fit Criteria, such as the position of the frame rims relative to facial features such as eyes or eyebrows
In the above method, it is not easy to take into account that the fitting guideline assigned to the corresponding spectacle frame

Embodiment Construction

[0088] 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.

[0089] 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 provides a method, a device and a computer readable storage program for the virtual fitting of a spectacle frame. The invention relates to a method for adjusting spectacles in which a virtual fitting process of a parametric frame model of a spectacle frame on a 3D model of the head of a person, to whom the spectacles are to be fitted, is divided into two fitting processes. In a first fitting process, the parametric frame model is adjusted to the 3D model of the head to meet specific fitting guidelines for the parametric frame model. Fitting guidelines of this nature may be specified by a frame manufacturer in order to comply with aesthetic criteria in the fitting. Anatomic fitting is then performed in a second fitting process.

Description

[0001] This application is a patent application with an application date of July 5, 2018, an application number of 201880057583.8, an international application number of PCT / EP2018 / 068222, 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...
