Description

[0001] VIRTUAL FITTING SYSTEM [0002]

The present invention relates to a virtual fitting system for synthesizing clothing data to a virtual body of a user using virtual body data and clothing data.

Modern people who emphasize personality have become popular to use the Internet as means of acquiring information to find the fashion that is trendy and the fashion that suits them. Due to this trend, a variety of shopping malls have emerged on the Internet, and one of the most popular areas is clothing and fashion goods including those. Users purchasing fashion goods using the Internet make full use of the temporal and spatial freedom provided by the Internet, purchasing desired products without using any physical effort at a desired time.

When the user confirms the image provided on the web page of the fashion product mall and is interested in the image of the posted product, the user can select the image and confirm the detailed information and purchase the product.

In the case of fashion products, in the case of fashion products, when a product that looks good in the image is received, it often receives a different feeling from the image. As a result, the product is returned or returned, , Resulting in financial damages.

To solve such a problem, there is a fashion information providing method through the Internet. The method of providing fashion information through the Internet may include providing a coordination service that displays user information in a database and compositing the product and the body form, or creates a virtual model input by the user to generate image data of clothing items, such as clothes, glasses, shoes, There is a method of providing a coordinated solution by pre-fitting a product selected by the user.

However, since the coordination service on the Internet uses a virtual model in cyberspace rather than the real one, when the user actually wears a fashion product such as clothes or hats on his / her body, he or she can use the entirety of his or her taste, body characteristics, skin, It is not possible to confirm that the harmony is correct. Therefore, after the purchase of the product, the product was not satisfied with the product and the product was frequently returned.

In addition, the consumer may go to an offline department store or a shopping mall to see the clothes on their body and then judge whether they are suitable for themselves. There are many cases where clothes are returned or exchanged.

Consumers buy offline and buy a fashion product, but they also return it. As a matter of fact, consumers' satisfaction with fashion products purchased on the Internet is much lower.

Due to these problems, online shopping service is still inferior in reliability and satisfaction to consumers.
