Abstract

Techniques for extraction of body parameters, dimensions and shape of a customer are presented herein. A model descriptive of a garment, a corresponding calibration factor and reference garment shapes can be assessed. A garment shape corresponding to the three-dimensional model can be selected from the reference garment shapes based on a comparison of the three-dimensional model with the reference garment shapes. A reference feature from the plurality of reference features may be associated with the model feature. A measurement of the reference feature may be calculated based on the association and the calibration factor. The computed measurement can be stored in a body profile associated with a user. An avatar can be generated for the user based on the body profile and be used to show or indicate fit of a garment, as well as make fit and size recommendations.

First claim

What is claimed is:

1. A method comprising:
accessing, from a database by a computer system, a three-dimensional model descriptive of a garment, the three-dimensional model having a model feature identifying a characteristic of the garment;
accessing, by the computer system, a corresponding calibration factor for the three-dimensional model, the calibration factor indicating a size of the model feature of the garment;
accessing, from the database by the computer system, a plurality of reference garment shapes for a plurality of reference garments of different types of garments;
comparing, by the computer system, the three-dimensional model descriptive of the garment to the plurality of reference garment shapes for the plurality of reference garments of different types of garments;
selecting, by the computer system, a garment shape from the plurality of reference garment shapes corresponding to the three-dimensional model descriptive of the garment based on the comparison of the three-dimensional model descriptive of the garment with the plurality of reference garment shapes, the selected garment shape having a plurality of reference features identifying characteristics of the selected garment shape;
comparing, by the computer system, the model feature of the three-dimensional model descriptive of the garment to the plurality of reference features of the selected garment shape to determine a reference feature of the plurality of reference features of the selected garment shape that is similar to the model feature of the three-dimensional model descriptive of the garment;
associating, by the computer system, the determined reference feature from the plurality of reference features of the selected garment shape with the model feature of the three-dimensional model descriptive of the garment;
computing, by the computer system, a measurement of the reference feature based on the model feature using the calibration factor indicating the size of the model feature;
storing, by the computer system, the computed measurement of the reference feature in a body profile associated with a user that comprises one or more computed measurements of reference features; and
generating an avatar for the user based on the body profile including the computed measurement of the reference feature.

2. The method of claim 1 , wherein generating the avatar further comprises:
selecting a first avatar from a database of reference avatars based on the body profile, the first avatar having a feature measurement less than the computed measurement of the reference feature;
selecting a second avatar from the database of reference avatars, the second avatar having a feature measurement more than the computed measurement of the reference feature; and
generating the avatar for the user by interpolating the first avatar and the second avatar.

3. The method of claim 2 , wherein selecting the first avatar comprises:
computing a difference vector for each of a subset of avatars in the database of reference avatars, each difference vector being based on the computed measurement of the reference feature and the feature measurement of each avatar in the subset of avatars; and
selecting the first avatar from the subset of avatars based on the difference vector of the first avatar being less than the difference vector of remaining avatars in the subset of avatars.

4. The method of claim 2 , wherein the interpolating the first avatar and the second avatar includes:
linearly interpolating between the feature measurement of the first avatar and the feature measurement of the second avatar.

5. The method of claim 1 , wherein the body profile includes a rise measurement, an inseam measurement, a waist measurement, a chest measurement, a thigh measurement, or a calf measurement.

6. The method of claim 1 , wherein the body profile includes a gender indicator that corresponds to the user, and wherein measurements stored in the body profile differ based on the gender indicator.

7. The method of claim 1 , wherein the three-dimensional model further includes material properties, the method further comprising:
presenting, on a display of a device, the three-dimensional model with a fit map based on the material properties and the body profile, the fit map having force data associated with a fit of the garment.

8. The method of claim 1 , further comprising:
presenting, on a display of a device, the three-dimensional model draped on the avatar for the user.

9. The method of claim 1 , wherein the three-dimensional model is based on multiple photographs of the garment, and the calibration factor is generated based on an object of a pre-determined size in a photograph from the multiple photographs.

10. The method of claim 9 , wherein the size for the model feature is calculated by measuring the model feature in a photograph from the multiple photographs, and multiplying the measured model feature by the calibration factor.

11. The method of claim 1 , wherein the calibration factor is different for different zones of the garment.

12. The method of claim 1 , wherein the three-dimensional model is based on multiple photographs of the garment, and the calibration factor is based on a photograph from the one or more photographs having a tiled background with a pre-determined size of tile.

13. The method of claim 1 , further comprising:
determining a size from a set of sizes for another garment based on the body profile associated with the user.

14. The method of claim 1 , wherein the body profile includes a fit preference based on a purchase history of the user.

15. The method of claim 1 , wherein the generating of the avatar is performed by a graphics processing unit in the machine.

16. The method of claim 1 , wherein the accessing of the reference garment shapes is performed by a wireless transceiver.

17. A system comprising:
one or more processors; and
a non-transitory machine-readable storage medium comprising instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
accessing a three-dimensional model descriptive of a garment, the three-dimensional model having a model feature identifying a characteristic of the garment;
accessing a corresponding calibration factor for the three-dimensional model, t calibration factor indicating a size of the model feature of the garment;
accessing, from a database, a plurality of reference garment shapes for a plurality of reference garments of different types of garments;
comparing the three-dimensional model descriptive of the garment to the plurality of reference garment shapes for the plurality of reference garments of different types of garments;
selecting a garment shape from the plurality of reference garment shapes corresponding to the three-dimensional model descriptive of the garment based on the comparison of the three-dimensional model descriptive of the garment with the plurality of reference garment shapes, the selected garment shape having a plurality of reference features identifying characteristics of the selected garment shape;
comparing the model feature of the three-dimensional model descriptive of the garment to the plurality of reference features of the selected garment shape to determine a reference feature of the plurality of reference features of the selected garment shape that is similar to the model feature of the three-dimensional model descriptive of the garment;
associating the determined reference feature from the plurality of reference features of the selected garment shape with the mode
