Abstract

A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. The system provides three-dimensional previews of their designs on a mannequin, using light projection techniques.

First claim

The invention claimed is:

1. A method comprising:
providing a garment previewing tool that allows previewing on a computer screen of a garment base customized by a user with a finishing pattern, wherein the garment previewing tool includes
providing an option for the user to select the garment base and upon the user's selection, showing a first garment preview image on the computer screen comprising a jeans base image for the selected garment base,
providing an option for the user to select a wear pattern from a menu of wear patterns, wherein each wear pattern is associated with a laser input file to be used by a laser to produce that wear pattern onto a jeans garment,
after the wear pattern is selected, showing a second garment preview image on the computer screen comprising the selected wear pattern in combination with the jeans base image, wherein the second garment preview image replaces the first garment preview image,
in the second garment preview image, allowing the user to select the wear pattern and modify a sizing of the wear pattern relative to the jeans base image, wherein as the user makes changes, the modified sizing of the wear pattern is displayed to the user in response to selecting the wear pattern,
in the second garment preview image, allowing the user to select the wear pattern and modify a position of the wear pattern relative to the jeans base image, wherein as the user makes changes, the modified positioning of the wear pattern is displayed to the user in response to modifying the position of the wear pattern, and
showing a third garment preview image on the computer screen comprising the jeans base image and selected wear pattern, with modified sizing or modified positioning, or a combination;
applying a distortion to the third garment preview image, wherein the distortion approximates how the jeans base image and selected wear pattern, with modified sizing or modified positioning, or a combination, needs to be modified to appear on a three-dimensional mannequin;
projecting, using a light projector, onto the three-dimensional mannequin the distorted garment preview image;
receiving a first captured image of the distorted garment preview image as projected onto the three-dimensional mannequin;
refining, based on the first captured image, the distorted garment preview image;
providing a target garment corresponding to the garment base selected by the user; and
based on a laser input file associated with a selected wear pattern with modified sizing or modified positioning, or a combination, using a laser to create a finishing pattern on an outer surface of the target garment.

2. The method of claim 1 comprising before projecting, using a structured light technique to determine contours of the three-dimensional mannequin.

3. The method of claim 1 wherein the third garment preview image includes at least one of a label, fastener, buckle, embellishment, embroidery, grommet, heat transfer pattern, lace, patch, printing, foil, ribbon, tab, foil, rivet, sequin, pocket, thread, or zipper.

4. The method of claim 1 wherein the step of refining the distorted garment preview image is repeated using subsequent captured images.

5. The method of claim 1 comprising:
before refining the distorted garment preview image, comparing the first captured image and the third garment preview image without distortions to calculate a difference ratio, wherein the step of refining the distorted garment preview image is in response to determining the difference ratio is higher than a threshold ratio.

6. The method of claim 1 wherein refining the distorted garment preview image comprises modifying the distorted garment preview image based on at least one of a contour of the three-dimensional mannequin, warp, brightness level of the first captured image, color balance, saturation level, or hue.

7. The method of claim 1 wherein the three-dimensional mannequin comprises legs.

8. The method of claim 1 wherein the three-dimensional mannequin comprises a full-body.

9. The method of claim 1 wherein the third garment preview image is generated before using the laser to create the finishing pattern.

10. The method of claim 1 wherein a method of manufacturing the target garment comprises:
assembling the target garment from fabric panels of a woven first material comprising a warp comprising indigo ring-dyed cotton yarn, wherein the fabric panels are sewn together using thread.

11. The method of claim 1 wherein based on the laser input file, the laser removes selected amounts of material from the surface of a material of the target garment at different pixel locations of the garment, and
for lighter pixel locations of the finishing pattern, a greater amount of the indigo ring-dyed cotton warp yarn is removed, while for darker pixel locations of the finishing pattern, a lesser amount of the indigo ring-dyed cotton warp yarn is removed.

12. The method of claim 1 wherein when using the laser to create a finishing pattern, different laser levels are obtained by varying an output of the laser beam by altering a characteristic of the laser comprising at least one of a frequency, period, pulse width, power, duty cycle, or burning speed.

13. The method of claim 1 wherein the target garment is made of at least one of a twill material or a cotton twill material.

14. The method of claim 1 wherein the garment base corresponds to a base fit fabric and the base fit fabric includes known characteristics regarding the suitability of the base fit fabric for finishing using the laser.
