The keypoint generator 210 may display a plurality of keypoints for each body part on the front image and the side image received from the receiver 100 . Each keypoint may be displayed at the center of the body part where the corresponding keypoint is displayed, but is not necessarily limited thereto.

A plurality of key points may be displayed on at least one of the user's eyes, neck, shoulders, chest, waist, hips, elbows, wrists, knees, and ankles.

For example, the plurality of keypoints include a first keypoint (1) displayed on the user's eyes, a second keypoint (2) displayed on the user's neck, a third keypoint (3) displayed on the user's shoulder, and a user's chest. 4th keypoint (4) displayed on the user's waist, 5th keypoint (5) displayed on the user's hip, 6th keypoint (6) displayed on the user's elbow, 7th keypoint (7) displayed on the user's elbow, user The eighth keypoint 8 displayed on the user's wrist, the ninth keypoint 9 displayed on the user's knee, and the tenth keypoint 11 displayed on the user's ankle may also be included.

Meanwhile, the keypoint generator 210 uses various known image analysis algorithms such as Harriscorner detector, Shi & Tomasi, SIFT (Scale Invariant Feature Transform), SURF, BRIEF, etc. to extract a plurality of keypoints from the front image and the side image. available.

The image mapping unit 220 may enlarge or reduce the front image or the side image so that the key points of the front image and the side image are positioned at the same height. Accordingly, the front image and the side image may be adjusted to the same size even though they are images taken at different distances.

In particular, when the image mapping unit 220 uses the keypoints located at the eyes and ankles of the front image and the keypoints located at the eyes and ankles of the side image during image mapping, it is confirmed that the mapping precision is the highest. For example, the image mapping unit 220 places the first keypoint 1 of the front image and the first keypoint 1 of the side image at the same height, and then places the tenth keypoint 11 of the front image and the first keypoint 1 of the side image. The front image or the side image may be enlarged or reduced until the 10th keypoint 11 of is located at the same height.

The image segmentation unit 230 may separate the user's body region from the background region in the front image and the side image.

Therefore, a boundary line may be formed along the boundary of the user's body region of the front image and the side image, and this may be used to calculate the circumference of each body part as will be described later.

Meanwhile, the image segmentation unit 230 may use various known image segmentation algorithms for body region separation.

In addition, the image segmentation unit 230 may smoothly transform the boundary line of the body region using OPEN CV's erosion/expansion technology during image segmentation.

Image processing by the keypoint generating unit 210, the image mapping unit 220, and the image segmentation unit 230 is not limited to the order shown in the drawings and may be performed in various orders.

First, the image analysis unit 240 may measure or calculate the body size from the front image and the side image.

For example, the image analyzer 240 may measure a body size, for example, an arm length or a leg length, by measuring distances between a plurality of key points.

As another example, the image analyzer 240 may calculate the circumference for each body part using the following equation.

In the above equation, C may mean the circumference of each body part, a may mean the width of the corresponding body part in the front image, and b may mean the width of the corresponding body part in the side image.

For example, the image analysis unit 240 may select two key points (4, 6) closest to the top and bottom of the waist in the frontal image when obtaining the waist circumference, and select the two selected key points (4, 6). 6), a point with the smallest width of the body region can be extracted. As a result, the waist width (a) in the front image can be obtained by measuring the width of the body region at the extracted point, and the waist width (b) in the side image is the width of the body region at the same height as the extracted point. It can be obtained by measuring the width.

For another example, the image analysis unit 240 may select two key points (2, 5) that are closest to the top and bottom of the chest in the side image when obtaining the chest circumference, and select the two selected key points (2). , 5), an inflection point of the body region boundary, for example, a point where the slope of the left boundary of the body region changes from a positive value to a negative value as it goes downward, may be extracted. As a result, the chest width (b) in the side image can be obtained by measuring the width of the body region at the extracted inflection point, and the chest width (a) in the front image is the width of the body region at the same height as the extracted inflection point. It can be obtained by measuring the width.

For another example, the image analysis unit 240 may select two key points (5, 9) closest to the top and bottom of the hip in the side image when obtaining the hip circumference, and select the two key points ( 5 and 9), an inflection point of the boundary of the body region, for example, a point where the gradient of the right boundary of the body region changes from a negative value to a positive value as it goes downward may be extracted. As a result, the chest width (b) in the side image can be obtained by measuring the width of the body region at the extracted inflection point, and the chest width (a) in the front image is the body region at the same height as the extracted inflection point. can be obtained by measuring the width of

Meanwhile, various image analysis techniques may be used when obtaining an inclination at a body region boundary to extract an inflection point.

For example, after calculating image weights in the x-direction and y-direction using Sobel's x-direction filter and y-direction filter at each pixel located at the boundary of the body region, the inclination point is calculated by calculating the tilt angle at the corresponding pixel. this can be extracted.

As another example, the neck, thigh, arm, and leg circumferences may be calculated using a circle circumference formula after measuring the diameter in a front image or a side image.

Next, the image analysis unit 240 may calculate a conversion ratio by comparing the body size measured or calculated as described above with the key information received from the receiver 100,

The actual body size may be detected by multiplying the calculated conversion ratio by the measured or calculated body size.

For example, if the height calculated by the image analysis unit 240 is A cm and the height received by the receiver 100 is B cm, the conversion ratio may be B divided by A, that is, B/A. .

More specifically, as shown in FIG. 10 , when processing clothes for an avatar whose size has been changed, a collision area through which the clothes are pierced may occur.

In order to prevent and correct this, the collision correction processing unit includes a collision mesh detection unit that predicts and detects a collision mesh generated when the synthetic avatar is generated, an exception range setting unit that sets an exception range corresponding to the collision mesh, and the exception range. to the fitting unit, and a dressing processing unit processing clothes corresponding to the 3D synthesized avatar, and a masking correction unit masking and correcting a collision region generated in the dressing processing.

More specifically, a 3D object starts with a point form of vertices, creates a plane, and finally displays it on the screen as a model.

Considering this, as shown in FIG. 11, the collision mesh detector approaches the position value of the vertices of the avatar and generates a ray (line) capable of detecting collision in the normal (vertical) direction from that position to the inside of the avatar. If the Ray (line) collides with the mesh of the clothing, the masking correction unit can set a masking value that makes the triangles (polygons) of the avatar mesh invisible.

However, as shown in FIG. 12(1), when a collision is detected using only the location values of vertices rather than planes, a portion that cannot be masked may occur.

Therefore, as shown in FIG. 12(2), the exception range setting unit according to the embodiment of the present invention expands the detection range from Ray (line) to Sphere (spherical shape) after step 1 to detect the non-collision part. As a result, all values within the sphere can be masked.

And, as shown in FIG. 12(3), the exception range setting unit according to the embodiment of the present invention generates a masking portion of the avatar mesh up to the boundary between the clothes and the avatar during the masking process in the form of a sphere.

A pointing unit, a side rotation angle calculator calculating a side rotation angle using the first pointing point and the second pointing point, and a correction application unit correcting the front image or the side image based on the side rotation angle do.

More specifically, the chest measurement method using two pictures (front and side) is calculated using the front and side lengths. If the measurement of the front or side length is incorrect, the chest circumference calculation becomes inaccurate. As a condition for accurate circumference calculation, it is important to accurately measure the length of the front and side. Usually, body rotation rarely occurs during frontal shooting, but body rotation often occurs when looking at the camera during side shooting.

Therefore, the profile correction unit 250 according to an embodiment of the present invention obtains a rotation angle of a person when photographing a side profile in order to accurately measure a side length, and calculates an accurate side length using the rotation angle and the front length.

To this end, the profile correction unit 250, as shown in FIG. 16, calculates each pointing position of the body using deep learning (Human Pose Estimation) in the front and side photos, and uses this position to You can find the angle of rotation.

More specifically, if x1 calculated based on deep learning from the first pointing points is the length of both shoulders on the front image, and x2 calculated based on deep learning from the second pointing points is the length of both shoulders on the side image, The lateral rotation angle is calculated as in Equation 2 below.

And, as shown in FIG. 17, the side length can be calculated as an accurate value using the rotation angle of the person calculated based on the side rotation angle, and the calculation formula for this is as shown in Equation 3 below. .

Here, X1 is the front length, X side is the measured side length, X2 is the actual side length, θ is the side rotation angle obtained by Equation 2, and adj is the rotation angle correction value. This is a value calculated using a correction value statistics table according to body shape and rotation angle through analysis of measurement values of a large number of people.
