Abstract

A method and system for evaluating fitness between a wearer and eyeglasses worn by the wearer, the method comprising steps of: generating facial attribute data associated with the wearer; generating attribute data of the eyeglasses; establishing wearer model based on the facial attribute data; establishing eyeglasses model based on the eyeglasses attribute data; comparing the wearer model and the eyeglasses model and evaluating the fitness there between; and generating a rating score information indicative of to which extent the eyeglasses improves the wearer visage based on the fitness evaluation result. By means of this method, the wearer of the eyeglasses can easily learn the matching/fitness degree of the eyeglasses worn by the wearer with his or her face, so as to help the wearer to decide whether or not to purchase or use the eyeglasses.

Claims

1. A method for evaluating fitness between a wearer and eyeglasses worn by the wearer, the method comprising steps of:

generating facial attribute data associated with the wearer;

generating eyeglasses attribute data of the eyeglasses;

establishing a wearer model based on the facial attribute data;

establishing an eyeglasses model based on the eyeglasses attribute data;

comparing the wearer model and the eyeglasses model and evaluating the fitness there between; and

generating, based on a result of a fitness evaluation, a rating score information indicative of an extent the eyeglasses improves wearer visage.

2. The method of claim 1, wherein the step of generating the facial attribute data comprises steps of:

capturing at least one image of the wearer, wherein the image has at least two dimensions;

detecting a face in the image; and

characterizing facial attributes of the wearer.

3. The method of claim 1, wherein the wearer receives information including at least one image of the wearer fitted with the eyeglasses along with a corresponding rating score information.

4. The method of claim 3, wherein said information is sharable via social network.

5. The method of claim 3, wherein the wearer receives a recommendation of other eyeglasses which would bring higher rating score.

6. The method of claim 5, wherein at least one of the eyeglasses and a recommended glasses is linked to an on-line store that provides the at least one of the eyeglasses and the recommended eyeglasses for the wearer to purchase.

7. The method of claim 1, wherein the step of establishing wearer model comprises a step of establishing metadata of the wearer, the metadata of the wearer at least comprising:

metadata on face shape of the wearer; and

metadata on eye shape of the wearer.

8. The method of claim 7, wherein the step of establishing eyeglasses model comprises a step of establishing metadata of the eyeglasses which includes characters of a frame and lens of the eyeglasses.

9. The method of claim 8, wherein the step of comparing the wearer model and the eyeglasses model and evaluating fitness there between comprises steps of:

pre-evaluating the wearer model and the eyeglasses model in a kernel database;

comparing and evaluating the metadata of the wearer in the kernel database;

comparing and evaluating the metadata of the eyeglasses in the kernel database; and

generating an evaluation matrix based on the steps of pre-evaluating the wearer model and the eyeglasses model, comparing and evaluating the metadata of the wearer, and comparing and evaluating the metadata of the eyeglasses.

10. The method of claim 9, wherein the kernel database at least comprises a database of wear models and a database of eyeglasses models which are obtained by big data analysis and is adapted to be updated by adding at least one of new wear models and new eyeglasses models when said models are not included in the kernel database.

11. The method of claim 9, wherein the step of creating a rating score further comprises a step of creating weighted scores based on the evaluation matrix.

16. The method of claim 2, wherein the wearer receives information including at least one image of the wearer fitted with the eyeglasses along with a corresponding rating score information.

17. the Method of claim 2, wherein the step of establishing the wearer model comprises a step of establishing metadata of the wearer, the metadata of the wearer at least comprising:

metadata on face shape of the wearer; and

metadata on eye shape of the wearer.

12. A system for evaluating fitness between a wearer and eyeglasses worn by the wearer, the system comprising:

an attribute data generating module for generating facial attribute data associated with the wearer and eyeglasses attribute data;

a model establishing module for establishing a wearer model based on the facial attribute data and an eyeglasses model based on the eyeglasses attribute data;

an evaluating module for comparing the wearer model and the eyeglasses model and evaluating fitness there between; and

a rating score generating module for generating and indicating a rating score associated with an extent the eyeglasses improves wearer visage based on a result of a fitness evaluation.

13. The system of claim 12, wherein the system further comprises an image capture device for capturing at least one image of the wear, and the system further comprises a displaying device for displaying at least one image showing how the wearer would appear wearing the eyeglasses along with a corresponding rating score.

14. A system for evaluating fitness between a wearer and an eyeglasses frame intended to be fitted by the wearer, the system comprising:

a processor for executing computer-executable instructions;

a computer readable storage media having stored thereon computer-executable instructions for;

generating facial attribute data associated with the wearer;

generating eyeglasses attribute data;

establishing a wearer model based on the facial attribute data;

establishing an eyeglasses model based on the eyeglasses attribute data;

comparing the wearer model and the eyeglasses model and evaluating fitness there between; and

generating, based on a result of a fitness evaluation, a rating score associated with an extent the eyeglasses improves wearer visage.

15. A method for evaluating fitness between a wearer and a head-worn device worn by the wearer, the method comprising steps of:

generating facial attribute data associated with the wearer;

generating attribute data of the head-worn device;

establishing a wearer model based on the facial attribute data;

establishing a head-worn device model based on the attribute data of the head-worn device;

comparing the wearer model and the head-worn device model and evaluating the fitness there between; and

generating, based on a result of a fitness evaluation, a rating score information indicative of an extent the head-worn device improves wearer.

18. The method of claim 15, wherein the step of generating the facial attribute data comprises steps of:

capturing at least one image of the wearer, wherein the image is a two-dimensional or three-dimensional image;

detecting a face in the image; and

characterizing facial attributes of the wearer.

19. The method of claim 18, wherein the wearer receives information including at least one image of the wearer fitted with the head-worn device along with a corresponding rating score information.

20. The method of claim 15, wherein the wearer receives information including at least one image of the wearer fitted with the head-worn device along with a corresponding rating score information.
