Description

[0001] BODY MEASURING SYSTEM USING POINT GROUP [0002]

The present invention relates to a system for measuring a user's body, and more particularly, to a body measurement system using a point cloud.

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.

The virtual coordinate investigation unit 10 emits a point cloud PG composed of a plurality of points P1. The virtual coordinate investigation unit 10 can display a point cloud PG on the user's body 120 using a scanner including a projector.

The virtual coordinate investigation unit 10 can irradiate the user's body 120 with a point group PG consisting of a plurality of points P1 arranged at predetermined intervals. The virtual coordinate survey unit 10 may include a shape control module 11 and a quantity control module 12. [

The shape control module 11 can check the user's body of the point cloud PG having a different shape according to the measurement position and the user's body size. The shape control module 11 can irradiate the point group PG of the t-shirt shape by arranging the points P1 in a T-shape as shown in FIG. 2 when irradiating the point group PG on the upper body. In addition, the shape control module 11 can arrange the points into a pants shape when irradiating a point group (PG) on the lower body.

Meanwhile, the shape control module 11 can control the shape of the point group PG in consideration of the user's key and weight input. For example, the shape control module 11 can emit a point cloud (PG) having different sizes in the case of an adult male and a child. The shape control module 11 can control the size of the point group PG to be basically smaller than the size of the body.

The quantity control module 12 controls the number of points P1 forming the point group PG according to the shape of the point group PG. In addition, the quantity control module 12 can control the number of points P1 according to the accuracy of the body dimensions to be measured. The quantity control module 12 can control the number of points from several hundreds to several thousands.

The reference position measuring unit 20 measures the position of the points P1 projected on the user's body.
