Description

Virtual fitting system {VIRTUAL FITTING SYSTEM}

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 generally used the Internet as a means of obtaining information to find current fashion and fashion that suits them. Due to this trend, various shopping malls have been created on the Internet, and one of the most prominent fields is clothing and a fashion goods mall including the same. Users who purchase fashion products using the Internet make full use of the time and space freedom provided by the Internet to purchase and use the desired products without physical effort at the time they want.

When a user checks an image provided on a web page of a fashion product mall and is interested in an image of a posted product, the user selects it to check detailed information and a purchase is made.

In the case of a fashion product, the fashion product often receives a different feeling from the image when the product that looked good in the image is actually received, which causes the product to be returned or returned, resulting in a timely response to the mall operator, product producer, and buyer. There is a problem that causes financial damage.

Invented to solve this problem is a fashion information providing method through the Internet. The fashion information providing method through the Internet provides a coordination service that displays a database of user information, synthesizes a product and a figure, or creates a virtual model input by a user, thereby providing image data on clothing products such as clothes, glasses, shoes, and hats. There is a way to provide Cody solution by pre-coating the product of your choice.

However, the provision of coordination services on the Internet uses virtual models in cyberspace rather than the real ones, so when the body actually wears fashion products such as clothing and hats, the overall coordination with taste, physical characteristics, skin and hair color It was not possible to confirm that the harmony was correct and accordingly, after the purchase of the product, the product was not satisfied with the product and returned frequently.

In addition, consumers may go to an offline department store or shopping mall, take a look at their clothing, and do not decide whether it suits them on the spot, but buy it after they buy it or try to listen to other people's opinions. As a result, clothing is often returned or exchanged.

When consumers wear clothes offline and buy fashion products and return them, it is natural that fashion products purchased on the Internet have a much lower satisfaction.

Due to these problems, the online shopping service is inevitably deteriorated in the reliability and satisfaction of the consumer.
