Abstract

Systems and methods are disclosed for best fitting a subject to a one of a plurality of object variations by capturing images of a user anatomical portion and a reference object from a plurality of angles using a mobile camera; creating a 3D model of the user anatomical portion from the images with dimensions based on dimensions of the reference object; and selecting a best-fit physical object from the plurality of object variations based on the 3D model.

Claims

1. A method for best fitting a subject to a one of a plurality of object variations, comprising:

capturing images of a user anatomical portion and a reference sheet from a plurality of angles using a mobile camera;

creating a model of the user anatomical portion from the images with dimensions based on dimensions of the reference sheet by;

identifying predetermined points of interest on the user anatomical portion;

selecting from a plurality of templates an anatomical template matching the predetermined points of interest;

morphing points on the anatomical template to match the points of interest;

generating in advance of image capturing one or more 3D deformable models for the user anatomical portion, and generating the model of the user anatomical portion by selecting a closest 3D deformable model to the user anatomical portion and warping points on the model to one or more predetermined points on the user anatomical portion; and

selecting a best-fit physical object from the plurality of object variations based on the model of the anatomical portion with the morphed points.

2. The method of claim 1, wherein the mobile camera comprises a smart phone or a portable camera.

3. The method of claim 1, wherein the user anatomical portion comprises a foot and the object variations comprises footwear, comprising matching the foot to the footwear or shoe based on selected sections and girths of the foot.

4. The method of claim 1, comprising monitoring user health using the model of the anatomical portion.

5. The method of claim 1, comprising analyzing the user anatomical portion as a body and selecting a best fit from apparel variations.

6. The method of claim 1, wherein the user anatomical portion comprises a face and the object variations comprises facial makeup products.

7. The method of claim 1, wherein the user anatomical portion comprises a head and the object variations comprises hairstyles.

8. A system for fitting a subject from a plurality of object variations, comprising:

a scanner to scan an anatomical portion of the subject using a camera, an infrared laser and an infrared camera, wherein the camera captures images while the infrared laser and camera determine distance between objects or to separate objects on different planes;

a processor coupled to the scanner for capturing images of a user foot portion on a reference sheet from a plurality of angles and creating a 3D model of the user anatomical portion using the one or more images and distance data from infrared images, the processor fitting the 3D model to a best-fit physical object selected from the plurality of object variations, and, generating in advance of image capturing, one or more 3D deformable models for the user foot portion, and generating the 3D model of the user foot portion by selecting a closest 3D deformable model to the user anatomical portion and warping points on the model to one or more predetermined points on the user foot portion.

9. The method of claim 8, comprising:

identify the subject'"'"'s current best fitting shoe products;

match the best fitting shoe product'"'"'s inside dimension with dimensions from the 3D model plus a predetermined gap;

correlating different manufacturer'"'"'s shoe sizes and creating correspondences among different manufacturer shoe products; and

recommending a new shoe for the subject by looking up the correspondences among different manufacturer shoe products.

10. A method for best fitting a subject to a one of a plurality of apparels, comprising:

capturing images of a user anatomical portion and a reference sheet from a plurality of angles using a mobile camera;

creating a model of the user anatomical portion from the images with dimensions based on dimensions of the reference sheet;

generating in advance of image capturing one or more 3D deformable models for the user anatomical portion and generating the model of the user anatomical portion by selecting a closest 3D deformable model to the user anatomical portion and warping points on the model to one or more predetermined points on the user anatomical portion; and

selecting a best-fit physical apparel from the plurality a apparel variations based on the model.

11. A method for best fitting a subject to a one of a plurality of object variations, comprising:

retrieving a pre-generated standard foot model;

capturing images of a user foot portion on a reference sheet from a plurality of angles using a mobile camera;

creating a user foot model from the images with dimensions based on dimensions of the reference sheet and morphing points on the pre-generated standard foot model to predetermined points of interest on the user foot portion;

generating in advance of image capturing one or more 3D deformable models for the user anatomical portion and generating the user foot model of the user foot portion by selecting a closest deformable model to the user foot portion and warping points on the model to one or more predetermined points on the user foot portion; and

selecting a best-fit physical object from the plurality of object variations based on the model of the anatomical portion with the morphed points.

12. The method of claim 11, comprising selecting a best-fit shoe based on the shoe'"'"'s inside dimension and a predetermined gap.

13. The method of claim 11, comprising:

selecting from a plurality of templates an anatomical template matching the predetermined points of interest;

morphing points on the anatomical template to match the points of interest.

14. The method of claim 11, comprising:

correlating different manufacturer'"'"'s shoe sizes and creating correspondences among different manufacturer shoe products; and

recommending a new shoe for the subject by looking up the correspondences among different manufacturer shoe products.

15. A method for best fitting a subject to a shoe, comprising:

capturing images of a user foot portion and a reference sheet from a plurality of angles using a mobile camera;

creating a model of the user foot portion from the images with dimensions based on dimensions of the reference sheet and predetermined points of interest on the user foot portion;

generating in advance of image capturing one or more 3D deformable models for the user anatomical portion, and generating the model of the user foot portion by selecting a closest 3D deformable model to the user foot portion and warping points on the model to one or more predetermined points on the user foot portion; and

selecting a best-fit physical shoe from the plurality of shoe variations based on the model.

16. The method of claim 15, comprising generating a 2D model of the foot.

17. The method of claim 15, comprising

selecting from a plurality of templates an anatomical template matching the predetermined points of interest;

morphing points on the anatomical template to match the points of interest; and

generating a multi-dimensional model of the foot.

18. The method of claim 15, comprising:

correlating different manufacturer'"'"'s shoe sizes and creating correspondences among different manufacturer shoe products; and

recommending a new shoe for the subject by looking up the correspondences among different manufacturer shoe products.
