The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the drawings for explaining a method of generating an avatar according to a user's body according to embodiments of the present invention.

1 is a flowchart illustrating a method for generating an avatar according to a user's body according to a preferred embodiment of the present invention, and FIG. 2 is a segment unit of a method for generating an avatar according to a user's body according to a preferred embodiment of the present invention. An embodiment showing the morphing technique.

The present invention relates to a technology for changing an avatar's body shape to a user's actual size during the development of a three-dimensional fashion show display system for a store that can reflect a user's avatar face, body type, hairstyle, accessories, and clothing in real time.

At this time, the body shape change technology of the avatar is a technology that can finely adjust not only the entire body shape of the avatar, but also detailed areas such as height, waist circumference, chest circumference, hip circumference, leg length, arm length, etc. It is to develop technology.

First of all, man and woman have to make a precise three-dimensional model of skinny, normal and obese body shape, and the basic vertex morphing technique so that the slide bar can be adjusted by the user to select the appropriate body shape among the three body types. The three body models are interpolated to produce representative models.

Here, the morphing technique is a technique of gradually changing an image, and the morphing implementation requires two or more images, such as an original image and an image to be changed, and transforms an image by finding a corresponding point between the plurality of images. It is mainly used in the back and can express extremely natural image processing technology.

Next, in order to allow the user to fine-tune the main body segments (segments) such as waist, chest, thighs, and calf through the slide bar, it is necessary to divide the avatar into segments. It is desirable to define a set of all points received.

Here, the segment refers to one continuous area of the storage device separated from each other.

At this time, when the slide bar is adjusted by the user, the positions of the three representative model segments are interpolated with each other to determine the position.

In order to allow natural morphing at the joints between the segments, the segments must overlap each other. For example, it is desirable to set the segment area so that the thigh and calf overlap the knee parts. This results in one point being affected by several segments and positioned by the settings of the various slidebars. The next step is to determine the degree of impact from the various segments.

This degree of influence can be calculated using the Heat Diffusion method used to obtain the skinning weight as shown in FIG.

At this time, Figure 2 is an example using the head diffusion method to obtain the skinning information in the game overgrowth, heat is generated in the center of the segment (left picture) and then transferred through the mesh (middle picture), all segments After applying this process to, we calculate the skinning weights as a percentage of the heat received from each segment (Figure 1).

Each segment is regarded as a heat generating body and heat is transferred from the center of the segment using the Heat diffusion equation. The heat diffusion equation is solved by Jacobi relaxation. After completion of constant iteration, the heat diffusion equation can be obtained. Here, the degree of influence from the segment on each point in the overlapping segment area is calculated by the ratio of rows received from each segment.

In the method for generating an avatar according to a user's body type according to a preferred embodiment of the present invention, first, a 3D model is generated for each body type of a man and a woman and stored in the avatar model DB (S100).

At this time, in the step (S100), it is preferable that the male and female three-dimensional models generated by being divided into a lean body type, a normal body shape, and a fat body type are stored in the avatar model DB, respectively.

Next, the avatar generation server extracts a three-dimensional model selected by the user from among the three-dimensional models stored in the avatar model DB in step S100, and uses the extracted model as an arm, a chest, a waist, a hip, a thigh, and a calf. When each of the body parts is adjusted by the user by subdividing the body parts of the deformation model to which the adjusted value is applied (S200).

Next, the avatar generation server generates an avatar by superimposing a deformation model applying a value of the body part adjusted by the user to the three-dimensional model extracted in step S200 by a morphing technique (S300). ).

In this case, the morphing technique is a technique of gradually changing the image by finding the corresponding points of the three-dimensional model that is the original image and the deformation model to which the body part value adjusted by the user, which is the image to be changed, is applied. to be.

Next, the avatar generated in step S300 is output (S400).

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
