FIG. 1 is a diagram showing a virtual fitting system 10. FIG. 2 is a flowchart showing a procedure for generating and registering physical property data and appearance image data of clothing in the virtual fitting system 10.

FIG. 3 is a flowchart showing a procedure in the virtual fitting system 10 for confirming how the user virtually tried on clothes selected at the virtual store.

The virtual fitting system 10 is a system that allows a user to check how a user virtually tried on clothes selected at a virtual store. The virtual fitting system 10 includes a body shape data generation unit 12, a fitting data generation unit 14, a display unit 16, a physical characteristic measurement unit 18, an imaging unit 20, and a storage unit 22.

The virtual fitting system 10 is in a state of being connectable to the user terminal 2 via the Internet. The user terminal 2 is a terminal such as a smartphone, a tablet terminal, or a personal computer.

The user uses the user terminal 2 or the like to input two-dimensional image data relating to the user and selects clothing to be tried on at a virtual store such as an EC site.

Clothes are clothes worn by the user, and include T-shirts, knits, sweaters, trainers, jeans, slacks, skirts, and the like. Of course, these are examples, and include not only outerwear but also underwear, and not only casual clothes but also formal clothes such as suits.

Here, the “real store” means a store that actually sells products side by side. On the other hand, the “virtual store” is a store in a virtual space (virtual space) and means a so-called online shop.

The body shape data generation unit 12 has a function of generating three-dimensional body data (for example, OBJ format) of the user based on a plurality of two-dimensional image data (for example, digital photograph data) for the user. Specifically, the three-dimensional body shape data of the user is obtained by using two or more pieces of photograph data of the photograph data of the user as seen from the front and the photograph data of the user as seen from the side.

In order to generate more accurate three-dimensional body shape data, it is preferable to use photograph data of the user's front, back, plane, bottom, left side, and right side in six directions, but the six directions are required. is not.

The fitting data generation unit 14 has a function of taking out clothing data regarding clothing selected by the user from the storage unit 22 and generating fitting data (fitting data) in which the clothing data is attached to the three-dimensional body shape data.

The clothing data has physical property data such as mass, elasticity, material thickness, friction coefficient, flexibility, tensile property, flexibility and resilience together with appearance image data of the clothes.

The clothing data is stored in the storage unit 22 after being generated using the physical characteristic measuring unit 18 and the image capturing unit 20 described later. For example, as shown in FIG. 2, the physical characteristic measuring process is performed using the function of the physical characteristic measuring unit 18 (S10), and the image capturing process is performed using the function of the image capturing unit 20 (S12).

The physical characteristic measuring unit 18 includes a fixed clamp and a movable clamp, and has a function of measuring the physical characteristic data while sandwiching the cloth of the clothing and applying a force to the cloth by using these clamps. Specifically, the cloth of the clothing to be registered in the storage unit 22 is cut out in the longitudinal (L), lateral (W), and bias (B) directions with respect to the ground stitch (texture).

Then, the sample taken out is weighed per m ² using a weighing function or the like. Then, the material sandwiched by the movable clamp approaches and contacts the fixed clamp to measure the material thickness, and the movable sample and the fixed clamp are loaded and fixed with the L sample in a long dimension.

Next, by sliding the movable side, the action and reaction value when the L sample hangs down and restores, and the resistance value generated when the movable clamp pulls the fabric with a predetermined force, the sensor built into the machine. Detected and digitized.

Then, the L sample is attached and fixed to the movable clamp and the fixed clamp with a short dimension, and the movable side slides, so that the movable sample has a predetermined sag, a restoring action and a reaction value in the convex and concave directions of the L sample. The resistance value generated when the fabric is pulled by the force of is measured and quantified.

By performing these steps for each of the W sample and the B sample, it is possible to quantify the physical properties of the fabric (fabric thickness, friction coefficient, flexibility, tensile property, resilience). Is stored in the storage unit 22.

The imaging unit 20 images the appearance (shape, pattern, color or combination of these) of the cloth of the clothing to be registered in the storage unit 22 and stores it as appearance image data.

The display unit 16 has a function of displaying a three-dimensional fitting image generated based on fitting data. Here, since the fitting data generated by the fitting data generation unit 14 includes redundant data including colors, patterns, physical parameters, body shape data, etc., only the appearance configuration data is left and the others are excluded. The filtered 3D fitting image is output and uploaded to the cloud service.

The three-dimensional try-on image output in this manner is confirmation data that can be visually recognized by rotating 360°. The display unit 16 has a function of notifying the URL for displaying the confirmation data of the fitting image on the cloud service on the web browser of the user terminal 2.

Next, the operation of the virtual fitting system 10 having the above configuration will be described with reference to the flowchart of FIG.

The user uses the user terminal 2 to perform a body shape data generation process (S20). Specifically, a plurality of pieces of photograph data relating to the user are registered, and the function of the body shape data generation unit 12 is used to generate three-dimensional body data in the OBJ format. In addition, the user selects clothing to be tried on on the EC site.

Next, a fitting data generation process is performed using the function of the fitting data generation unit 14 (S22). Specifically, the clothing data that the user desires to try on is attached to the user's three-dimensional body shape data generated in step S20 to generate the fitting data.

Then, the fitting data is dropped only to the data necessary for the user to visually recognize, and the three-dimensional fitting image rotatable by 360° is uploaded to the cloud service. Then, the URL for visual recognition is notified by the web browser of the user terminal 2 (S24).

Next, a fitting image display process is performed using the function of the display unit 16 (S26). Specifically, a three-dimensional fitting image is displayed so that the user terminal 2 can be used for confirmation by a web browser. Then, if necessary, it can be rotated 360° to check the rear view and the side view.

As described above, according to the virtual fitting system 10, the user can easily confirm, using the user terminal 2, the three-dimensional image data in which the clothing data desired to be tried on is attached to the three-dimensional body shape data of the user. it can.

Here, since the clothing data includes physical properties such as fabric thickness, friction coefficient, flexibility, tensile strength, and resilience, whether or not the clothing that is tried on suits the user (for example, there are not too many wrinkles. Whether the length is too short or not too long).

Further, since the three-dimensional image data is stripped of useless data and can be browsed on the cloud service so as to be rotatable by 360°, the user can enjoy the try-on more easily.

As described above, according to the virtual fitting system 10, in a virtual store such as an EC site, it is possible to easily confirm whether or not the clothes that one wants to wear look good, so that the user can more easily and easily store clothes in the virtual store. It has the remarkable effect that it can be purchased at.
