Abstract

Techniques for generating and presenting a three-dimensional garment model are presented herein. A communication interface can be configured to receive images, where all visible parts of the garment may be captured by the received images. A garment creation module can be configured to generate partial shapes of the garment based on the received images. Additionally, the garment creation module can determine a type of garment by comparing the generated partial shapes to a database of reference garment shapes. Furthermore, the garment creation module can generate a three-dimensional garment model by joining the partial shapes based on the determined type of garment, and can tessellate the generated three-dimensional garment model. A user interface can be configured to present the tessellated three-dimensional garment model on a three-dimensional body model.

Claims

1. A system comprising:

one or more processors;

a communication interface configured to;

receive a first image depicting a first view of a garment; and

receive a second image depicting a second view of the garment;

a garment creation module that configures at least one processor among the one or more processors to;

generate a first partial shape of the garment based on the received first image;

generate a second partial shape of the garment of the garment based on the received second image;

determine a type of garment by comparing the generated first and second partial shapes to a database of reference garment shapes;

generate a three-dimensional garment model by joining the first partial shape and the second partial shape based on the determined type of garment, the generated three-dimensional garment model including a first group of vertices; and

tessellate the generated three-dimensional garment model by adding a second group of vertices to the generated three-dimensional garment model; and

a user interface configured to present the tessellated three-dimensional garment model on a three-dimensional body model, the tessellated three-dimensional garment model being presented based on a simulated force.

2. The system of claim 1, wherein the garment creation module configures the one or more processors to tessellate the generated three-dimensional garment model by tessellating the generated three-dimensional garment model into triangles, wherein vertices in the triangles correspond to points that are interior to the generated three-dimensional garment model.

3. The system of claim 2, wherein overlaps and gaps do not exist between the triangles of the tessellated three-dimensional garment model.

4. The system of claim 2, wherein a triangle among the triangles of the tessellated three-dimensional garment model has a minimum angle, and wherein the garment creation module further configures the one or more processors to tessellate the generated three-dimensional garment model by maximizing the minimum angle of the triangle.

5. The system of claim 1, wherein the garment creation module configures the one or more processors to apply a texture map to the tessellated three-dimensional garment model by assigning a color to a vertex in the second group of vertices based the received first image.

6. The system of claim 1, wherein the garment creation module configures the one or more processors to determine actual dimensions of the garment using a reference object placed near the garment in the first image.

7. The system of claim 1, wherein the simulated force includes at least one of a gravitational force, a frictional force, or aerodynamic drag.

9. The system of claim 1, wherein the garment creation module configures the one or more processors to generate the first partial shape of the garment by:

calculating a difference in color between a pixel and its adjacent pixels within the first image; and

determining that the pixel is on a first edge of the first partial shape of the garment based on the difference transgressing a predetermined threshold value.

10. The system of claim 9, wherein the garment creation module configures the one or more processors to join the first and second partial shapes by aligning the first edge of the first partial shape with a second edge of the second partial shape.

11. The system of claim 9, wherein the garment creation module configures the one or more processors to smooth the first edge of the first partial shape into a smoothed curve by removing artifacts in the first image, wherein the artifacts is due to a lighting effect in the first image and an image compression of the first image.

12. The system of claim 1, wherein the garment creation module configures the one or more processors to generate a first flat-panel as the first partial shape and a second flat-panel as the second partial shape.

13. The system of claim 12, wherein the garment creation module configures the one or more processors to generate the three-dimensional garment model by joining at least a portion of the first flat-panel with at least a portion of the second flat-panel.
