The present invention relates to a method for determining a measurement point for each human body type (parts) and a recording medium that is programmed therein. More specifically, the human body dimension enables the production of personalized clothes by measuring the human body dimension more precisely. The present invention relates to a method of determining a measurement point for each body type (parts) for determining a body shape, and a recording medium that includes a program.

In general, it is of utmost importance to determine anthropometric points in custom-made garments. To this end, the automatic recognition method of anthropometric points can be divided into three types.

The first is to attach the marker to the subject before scanning and use image processing by color or brightness to detect the marker. This method requires a high resolution scanner to detect the marker, and has the disadvantage that the marker must be accurately attached to the human body before scanning, but has the advantage of good reliability. If it takes a lot of time to manually landmark before scanning in this way, the benefit of the speed gained from using a scanning system is reduced. In other words, the first method was not fast.

Secondly, there is a method of creating a deformable template model that is marked with a measurement point in advance and deformed according to each human scan data. In this case, a statistical method may be used to limit model deformation in a manner of matching the features of the human body shape. Using statistical numbers reduces the likelihood of producing the worst error because feature points will always be found in the correct position.

For example, using geometrical methods, a general feature model of the mannequin on the torso was created in advance, and then compared to this three-dimensional point cloud. Compute and align the center of gravity and the principal axis of the general feature model and the three-dimensional coordinate values to place the three-dimensional coordinate values on the general feature model, and then create a facet model from the general feature model and the three-dimensional coordinate city. Analyze the slope to recognize the breast point. The feature points of the general feature model and the three-dimensional coordinates are matched and the set of size factors is estimated. This method has a limitation that it is applied only to the form similar to the general feature model that has been set in advance. Therefore, it is difficult to apply the method as it is because the human body has a great individual difference and various body types exist. In other words, the second method was difficult to apply to various body types.

Thirdly, the pattern recognition method detects features based on the surface shape of each part of the human body while using contextual properties. This is usually accomplished by partitioning the area and creating a feature detection function based on local shape features such as curvature. This approach provides flexibility in that each feature detector can be modeled using a different expressive form. Input attributes can be of any type (shape, non-shape, local, global), and various shape description methods can be used.

For example, image analysis is performed on the cross-sectional shape of the human body, which is measured using a sliding gauge, and the section from the human neck to the upper part of the thigh is divided into 20 stages. The dog's radius data were obtained and reconstructed into an anatomical model on a cylindrical coordinate system. In addition, Fourier transform of point data in a cylindrical coordinate system can be used to create horizontal and vertical contour lines, and the main feature points can be detected by finding the maximum, minimum, maximum, minimum, or inflection points on the contour line.

However, it is not applicable to all humans with various shapes, and the Fourier transform does not provide an appropriate conversion rate by verifying the actual scan data value and the difference according to the degree of conversion. In addition, there was a problem that only the torso area was excluded except for the actual limb data.

On the other hand, there are programs such as BMS (U.S.A), DigiSize (U.S.A), Bodyline Manager (Japan), ScanWorks (Europe) that automatically measure the dimensions from the three-dimensional scan data using the above-described method. However, the measurement points or the measurement paths suggested in such a program are often inaccurate. Therefore, there is a problem that it is difficult to use the measured dimensions in these programs accurately and correctly for the user's purpose.

The present invention has been proposed to solve the above problems, and determine the measurement point based on the geometric forming features such as cross-sectional or silhouette line, surface slope or curvature on the human body surface or find a unique shape according to individual body features In case of difficulty, the object of the present invention is to provide a method for determining a measurement point for each body type (parts) for determining a measurement point using correlation with other measurement points, and to provide a recording medium in which the program is recorded.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, like elements are designated by like reference numerals.

1 and 2 are diagrams for explaining a method and a measurement point for determining the body point (by region) measurement point for determining the human body size according to an embodiment of the present invention.

According to an embodiment of the present invention, a method for determining a measurement point for each human body type for determining a human body size may be performed in a three-dimensional manner to be used in a human body measurement item such as height, circumference, length, and width to be measured according to characteristics of each human body part. x, y, z) is obtained from human body data. Three-dimensional (x, y, z) human body data is also referred to as three-dimensional human body scan data because it uses a scanner. Before the measurement point is set in the 3D human body scan data, a preprocessing process is performed.

The preprocessing of the 3D human body scan data consists of a process of uniformly editing the scan data surface, rotating the human body to face the front face, and dividing the arm, torso, and leg of the human body.

The reason why the scan data surface is uniformly edited is to give wrong information when trying to grasp the slope and curvature of the 3D data for automatic recognition in the 3D data, and as a result, the measurement point setting may fail. In addition, the reason why the human body is rotated to face the front exactly may not be exactly found when looking for the maximum minimum position of the front, back, left and right in the cross section if the human body is at an angle without looking directly at the front. In addition, even when measuring the thickness or width of each cross section, the front and rear or left and right gaps are not accurately determined, but the oblique gaps are obtained, so that they may be measured differently from the actual width. In addition, the reason for dividing the arm, torso, and leg of the human body is that the measurement time can be shortened and the accuracy can be improved by narrowing the search range of each measuring point through the human segmentation. On the other hand, as shown in Figure 1, the coordinate system of the three-dimensional human body scan data is the x-axis of the human body, the z-axis in the front and rear directions, the y-axis in the height direction.

In particular, the method of determining the measurement point for each human body type for determining the human body size according to an embodiment of the present invention includes a three-dimensional human body of three-dimensional (x, y, z) human body data to determine the measurement point for each human body type (part). Body shape or front shape, neck stiffness, shoulder tilt, shoulder pull that determine the measurement point based on geometric shape features such as cross section, side view, silhouette, surface tilt and curvature on the surface or divided into underweight, normal and overweight The measurement point is set by a regression equation using correlation with other measurement points on the 3D human body data when the individual differences are severe due to body factors divided into accuracy, lumbar frontal shape, and degree of bulge.

Here, the measurement points to be measured through the human body, as shown in Fig. 2, hair ridge point, hip protrusion point, spank furrow point, calf protrusion point, 딴 point, wrist side point, side copy point, armpit point, nipple point, lower breast point, Throat point, neck point, neck point, shield cartilage point, shoulder point, middle shoulder point, axillary front point (back wall point), ventral point, waist point and waist point (back waist point).

The head ridge is a point located on the head and points to the top of the midline of the head when the head level is maintained.

The point below the cartilage of the shield, the back of the neck, the front of the neck and the point of the neck are located at the neck. The neck point is the position where the neck line intersects the median midline at the circumference of the neck, and the lateral point indicates the position where it meets the upper front edge of the back quadriceps at the neck.

If you look at the point on the body, the shoulder point is where the front line along the length of the shoulder bone meets the line connecting the clavicle peak at the lateral point, and the axilla is the lowest position of the axillary fold line. The anterior wall point is located in the middle of the distance between the shoulder point and the armpit point, and the axillary point is located in the middle of the distance between the shoulder point and the armpit point, and the nipple point is the front of the bra cup for women with bras. Protruding into the nipple position in men.

Also, the lower breast point (female) is the lowest point where the breast is connected to the torso, and the lower lateral point is the most in the right side contour of the torso as seen from the front, or 1/2 of the distance between the tenth rib and the buttocks Waist front point is where the midline meets with the midline at the waist, Waist point is where the midline at the waist meets, and the ventral point protrudes forward from the abdomen. From the side, it protrudes to the rear of the buttocks, and the focal point (apical coupling point) indicates the middle of the genital and anal areas.

The measurement point set only by the geometrical features of the three-dimensional body surface is a point where the setting order does not matter, for example, the axillary point, nipple point, hip protrusion point, calf protrusion point, lower breast point point, inner wrist You can have a point, a wrist point, a blow furrow point. Examples of measuring points which are set only by such geometrical features of the three-dimensional body surface will be described in detail later.

The detection of the measurement point by the regression equation using the correlation with the other measurement points may be set after the reference measurement point is first set, for example, the neck point, neck point, neck point, waist point, fold out You can have points, shoulder points, axillary front points, and points. Examples are described in detail later.

Hereinafter, a method of searching (determining) a measurement point based on the aforementioned geometric shape features or regressively from three-dimensional human body data will be described.

3 to 5 are diagrams for explaining a method of setting the axillary point of the measuring point according to an embodiment of the present invention.

The scan data of the armpit area according to the embodiment of the present invention does not scan well, and the arm and the body meet from far below the actual axle in the case where the body is obese and the chest is small. As a result of measuring the height difference between the actual axillary point and the position where the arm and the torso begin to stick, it reaches 200mm in the case of normal body and 50mm in case of obesity. This is shown in Table 1.

                              Table 1

         Junction height-direct armpit height difference of arm and torso               female               male Body type (person)       Mean        SD       Mean       SD   Low weight (10)       -9.9       7.5       -9.7       5.2   Normal weight (10)      -27.5       16.3      -18.2       11   Overweight (10)      -45.5       20.5      -40.0       21.4

* SD: Standard Deviation

Therefore, the point where the arm and the body meet can not find the axillary point, first find the axillary junction. As shown in Figure 3, the front arm apart point (Front arm aparting point, Back arm aparting point) refers to the part where the inner side of the arm gradually disappears and the arm and torso start to separate from the arm. The axillary bifurcation point is different from the front, rear height according to the shape of the shoulder, as shown in Figure 3, the front of the arm can be high, as shown in Figure 3b, the arm can be high, as shown in c of FIG. The arms may be similar in height before and after.

Based on this, the method of setting the axillary point is first made a front silhouette between the arm and the torso. After that, the point where the height (y-coordinate value) is the highest in the silhouette is found, and this point is called a temporary armpit point as shown in d of FIG. 3. In other words, the temporary axillary point means that the 3D human body data is divided into a torso and an arm. Then, a cross section is made at a height interval of 2 mm starting from the height of the temporary axle. Thereafter, the concave point is obtained from each cross section, and as shown in FIG. 4A which shows a cross section under the axillary branch point, the concave point (Arm-Torso pit point) may be displayed as two points.

Then, as shown in b of FIG. 4 showing a cross section of the armpit bifurcation, the arm and torso separates the arm and torso when the arm data is inward from the arm indentation point in each cross section to the arm-torso aparting point. You can decide. At this time, the front and rear heights of the axillary branch point are different depending on the direction of the arm, so a reasonable setting should be made. For example, if the height of the axillary branch point is 90mm and the rear height is 80mm, the height of 85mm is a reasonable setting. In other words, as shown in FIG. 5, there is a midpoint that intersects the middle segment of the front and rear axillary junctions and the middle height of the front and rear axillary junctions, which is an armpit point.

6 and 7 are views for explaining a method of setting the wrist side point and the side copy point of the measurement point according to an embodiment of the present invention.

Referring to Figure 6, the measuring point according to the embodiment of the present invention is the wrist side point and the inner point of the wrist is a reference point of the arm length, the wrist side point is the side, the wrist inner point is inward in the palm facing forward position In the posture of the three-dimensional scan data used in the present invention, the wrist points to the inside of the side point. Based on this, the method of setting the wrist point is first made of the front silhouette of the arm, and then the middle height point of the hand's end and the armpit in the thumb point and the inner silhouette of the arm, In other words, find the line segment between the fingertip and the armpit.

Subsequently, when a point farthest from the line segment is found among the inner points of the silhouette arm, this point may be set as a wrist point.

Referring to Figure 7, the side of the measurement point in accordance with an embodiment of the present invention is the most protruding toward the side in the side copy, when comparing the x coordinate to find the most side silhouette point at the instep or calf height is the most It is preferable to narrow the range where the side copy point can be located (search height area, search depth area) and compare the x coordinates within the range before the x coordinate is compared.

Based on this, the method of setting the side radiation point is to first make a leg front silhouette. Then, a line segment having two points, the height of the inferior leg and the statistical minimum (μ-3δ), is created among the outer points of the silhouette. Find the point Max distance pt farthest from the vertical line.

Then, if the rightmost point (X minimum point, minimum X pt) is found from the silhouette from the height of the Max Distance pt to the height of the inferior leg, this point may be set to the lateral malleus. .

8 and 9 are views for explaining a method for setting the nipple point and the lower breast point of the measurement point according to an embodiment of the present invention.

Bust point according to an embodiment of the present invention, when setting the height, there are two ways.

That is, as shown in a of FIG. 8 which shows that the bust point is not the most protruding point of the side silhouette, the side slope symbol is not changed at the method and the method of setting the maximum protruding point from the side silhouette to the front. As shown in b of FIG. 8, which does not show, there is a method of using a point in which the slope changes to + while going from top to bottom in the side silhouette.

The first method does not fit well with poor chests, back obesity, or abdominal obesity because it protrudes more than the bust point. The second method works well for most women, but not for men. In other words, men often do not protrude most nipples, and the slope does not change to + is difficult to find.

Accordingly, it is preferable that the female is set in the second method, and the male is set to the position statistical values in Table 2 as follows, rather than searching for the geometrical features.

                                  TABLE 2

(Nipple point- 샅 height) / (Two point- 샅 height) man 0.678 (0.023) μ ± 2δ 0.633-0.723

In addition, the nipple point (Bust point) according to an embodiment of the present invention is not toward the front of the human body rather than toward the front of the human body when looking at the silhouette points from the left and right positions tend to be slightly outwards Therefore, the point that protrudes from the side forward may be the inner part of the nipple point, not the nipple point.

In particular, the more obese, the more nipple point is located on the inner side of the proximal point, the more obese the more the direction of the breast toward the outside. Therefore, in the embodiment of the present invention, it is preferable to adjust the left and right positions of the nipple point to be at the statistical average position. The formula for adjusting the nipple point left and right position to the statistical average position is as follows.

Female = right and left center at nipple height ± (chest width × 0.26), male = left and right center at nipple point height ± (chest width × 0.307). Through the above equation, the statistical mean of the ratio of the interval between the nipple points to the width of the breast is shown in Table 3 as follows.

                              TABLE 3

gender Item Horizontal length between nipple points Horizontal length / thickness ratio between nipple points female Average 156 mm 0.520 μ ± 3δ 113 mm to 199 mm 0.403-0.637 male Average 199 mm 0.614 μ ± 3δ 132mm to 265mm 0.491-0.736

Referring to FIG. 9, the lower breast point according to the embodiment of the present invention creates a sagittal section at Nipple passing through the nipple point. Then, in this cross section, the point (a), which is down from the nipple point (b) up and the nipple point (b), is lowered by the average + 3d + 5cm of the height difference between the nipple point and the breast. Make a line through point (a, b). The maximum distance pt is the furthest distance from the segment and can be set as the breast inferior pt.

10 is a view for explaining a method of setting the butt protrusion point and blowing furrow point of the measuring point according to an embodiment of the present invention.

The hip protrusion point of the measuring point according to the embodiment of the present invention is the point which protrudes most backward between the waist and the height of the waist, and the method of setting the hip protrusion point first makes a side silhouette. Then find the backmost point (the z-coordinate minimum) in the side silhouette and set it as the buttock protrusion. Referring to FIG. 10, the blowing furrow point of the measuring point according to the embodiment of the present invention creates a longitudinal section passing through the buttock protrusion.

Then, the back point (a) at the lowest height at which the blowing furrow can be located from the hip protruding point is determined using the statistics of 'hip height-blowing furrow height difference'. Then, find the point b that contacts the hips up from the thigh back point a. Make a line segment consisting of the two points a and b. Among the longitudinal points, find the maximum distance pt that is the longest vertical distance from the line segment, and set this point as the Gulute Fold.

11 to 15 are diagrams for explaining a method for setting the neck point of the measurement point according to an embodiment of the present invention.

Referring to Figure 11, the neck point of the measuring point according to an embodiment of the present invention is the most concave part where the neck and shoulder meet formally, the slope is sharply changed, the method of setting the height of the neck point first, the head Create a front silhouette between the head tip point and the shoulder point. When making a straight line from the top, the shoulder point that is the lower reference can be obtained by taking the average value of the height difference between the armpit point and the shoulder point and raising the mean value from the armpit point height.

Then, in the silhouette, make a straight line connecting two points, the shoulder point and the head repair point height. We then find the point where the vertical distance to the straight line in the silhouette is the furthest distance (Max Distance pt), which is the temp SNeck. Subsequently, the temp SNeck, which is a concave point when the upper point of the diagonal line is used as the head repair point, is found, and the vertical distance between the point and the head repair point is called 'the neck distance'. Next, make a diagonal line with the points on the diagonal line that are 1/4 (0.25), 1/2 (0.5), and 3/4 (0.75) high from the temporary neck point. Obtain and compare with actual neck point height.

As a result of the experiment, as the upper diagonal line is closer to the head parietal point, the concave point is about 5 to 6 mm higher than the actual neck point, and as the upper diagonal line goes down, it becomes closer to the actual neck point.

In other words, the point that is 1/4 and 1/3 of the neck distance from the temporary neck point shows a similar difference, but since the 1/4 point is smaller than the neck point directly, the point above the oblique point is the neck from the first neck point. The height raised by a quarter of the distance would be appropriate.

In addition, look at how to set the side position of the neck point as follows. The neck point is the intersection with the shoulder sloping line around the neck. The neck circumference is a factor that determines the front position of the neck point, and the shoulder sloping line is a factor that determines the side position of the neck point. At this time, the shoulder inclination line is composed of points forming a front silhouette, the points forming a front silhouette are left and right end points in each cross section. Looking at the points forming the front silhouette from the side, as shown in FIG.

Referring to FIG. 12, since the shoulder inclination line is formed of the front silhouette, the neck point may be in the front silhouette. Therefore, since the neck point serves as a reference for measuring the width of the neck, it is reasonable to have the neck point on the front silhouette line which is the left and right end points in each cross section. The point at the neck point on this front silhouette line is hereinafter referred to as the 'silhouette SNeck point'. However, since the silhouette neck point is different from the actual neck point depending on the body shape, as shown in FIG. 13, the bowed body shape or the obese body type has a silhouette silhouette point (silhouette SNeck pt) behind the actual neck point (Real SNP). Can be formed.

In the present embodiment, in order to determine whether the above-mentioned neck stiffness and obesity figure body factors actually affect the difference between the silhouette neck point and the direct point, the difference in the side position between the direct landmark of the neck point and the silhouette point is determined. This study compares the differences between groups according to the degree of slumbering and obesity.

To do this, first, a criterion for judging the degree of necking is needed. Therefore, the criterion of the degree of necking is the one that has the most correlation with the "side positional difference between the silhouette neck and the direct point" among the angles related to the neck. Here, the direct point refers to a measurement point for manually designating a landmark displayed on the three-dimensional scan data.

As shown in Fig. 14, the neck-related angles are a total of five, the neck angle (Fa) is the angle of the line segment consisting of the front point and the inside of the jaw point, neck back angle (NBa) is a line segment consisting of a point 26mm above the back point from the neck point Angle of the back, Ba is the angle of the line segment consisting of the mid-high point of the neck and the back of the neck, and B-NBa is the middle of the neck and the back of the neck. The angle of the line segment consisting of raised points and the front and back mean angle (FBa) are the average angles of the front and back angles.

As described with reference to FIG. 15, the angles related to the neck are all defined on the median sagittal plane, because the shape of the spine associated with the neck is best reflected in the medial sagittal plane. On the other hand, because the side silhouette follows the protruding shape of the shoulder blade, the side silhouette is often different from the shape of the back center, so it is not reflected well.

                                Table 4

  BMI   Neck angle (Fa) Neck angle (NBa) Angle of Angle (Ba)  Backward angle of angle (B-NBa) Average angle around the neck (FBa) Correlation coefficient  0.353     0.02 -0.486  -0.145    -0.243      -0.277

Accordingly, as shown in Table 4, as a result of examining the correlation between the lateral position difference between the silhouette neck point and the direct point and the neck angles, the back neck angle has the highest correlation, and the front angle or the back angle has a correlation. It appears to be missing. The neck angle is irrelevant because the neck point or the lower jaw, which is a measure of the neck angle, is easily fixed and does not reflect the actual tilt of the neck.

Based on the result that the difference between the silhouette neck and neck is directly related to the back of the neck, the degree of necking is divided into three groups according to the back of the neck, and the degree of obesity is divided into three groups according to the BMI. Find out how much the difference in lateral position from the point is between groups.

As shown in Table 4-1, the classification according to the degree of throating was done according to the percentile of the neck angle measurement of 150 women aged 20-69 years as measured in this example, and the left neck was less than 17.2 ° (25%). Were classified as 17.2 ° to 28.6, which ranged from 25 to 75%, and the tree was classified based on over 28 °, which is 75%. Men were also classified using this criterion.

*. The alphabets (a, b) represent groups with significant differences at the Dunkun test result of MAD (absolute difference) at P = 0.05, with the letters M, a, b, and c in larger order. Will.

As shown in Table 4-2, which is the result of experiment through the above classification, the lateral position between the silhouette neck point and the direct point differs according to the group of the bower's neck, and the silhouette neck point is formed behind the actual neck point as the head gets closer. Can be. In the human body type, the deviation also tends to be large. The Duncan test results show that only the Baptist group remained at the significance level of 0.05. Depending on the degree of obesity, there was no clear difference between groups and only slightly overweight groups.

On the other hand, in the embodiment of the present invention, as a method of setting the neck point, the method using the average and the standard deviation of the ratio value is located between the neck point and the neck point on the side. First, determine the range of the lateral position of the neck point and move it into the range if the neck point on the silhouette is outside this range.

The statistical values of the ratio between the neck point and the neck point are shown in Table 4-3. The location ratio of the neck point is not different between the sexes. Generally, it is regarded as an outlier when it is outside the average ± 3δ range, but the position of an anthropometric point is not beautiful when it is out of the average too much, so it is judged as an outlier when it is outside the average ± 2δ range, When adjusting, adjust to the nearest position within the 'mean ± 1δ' range.

The results of the difference in the lateral position of the lateral point and the direct point using the statistical range limitation method are shown in Table 4-4.

                                Table 4-4

      Lateral position (z) differences by group      Lateral position (z) difference by obesity group   Mean   MAD    SD  Comparison between body types  Mean   MAD     SD Comparison between body types Sleeping tree (20 people) -1.3   1.7  2.9       a   Low weight (20)  -0.8  1.4 2.5      a Right neck (20 people) -0.9   1.8  2.9       a  Normal weight (20)  -0.4  0.8 1.7      a Lean neck (20 people) -0.7   1.2  2.3       a    Overweight (20)  -0.8  1.8 3.5      a

Comparing these results with the lateral position results in Table 4-1, which did not limit the range, it was found that the difference was small in the lean and obese body. In the tree, the body size decreased from 3.1mm to 1.7mm, and in the obese body, it decreased from 2.8mm to 1.6mm. In addition, it can be seen that there is no significant difference between body types.

16 and 17 are diagrams for describing a method of setting a front point among measuring points according to an exemplary embodiment of the present invention.

As shown in Figure 16, look at the shape of the front of the neck in order to set the neck point of the measuring point according to an embodiment of the present invention, as shown in Figure 16a, the general side shape of the neck portion of the neck front point is the most concave, neck point Starting from the front of the neck upwards and then bent forward from the chin. The neck concave point (minZ pt) is equal to the neck point (FNeck). However, as shown in b of FIG. 16, as the weight increases, the fat is deposited on the center of the clavicle, and the concave point becomes unclear and concave upward from the height of the clavicle. In addition, fat is deposited in the lower jaw, so the jaw inner pt moves downward. Therefore, as the weight increases, the shorter point between the minZ pt and the jaw inner pt becomes shorter and the height of the two points may be the same.

Therefore, in the body without fat deposit on the clavicle, the neck point (FNeck) can be set as the most concave point in the side silhouette of the human body.However, if the fat is deposited in the front part of the neck, the concave point is much higher than the neck point. You can't do it as a forefront.

The height difference between the concave point and the actual neck point is 1.9mm, which is similar to the actual neck point, but the fat is located in front of the neck. The body shape is 10.4mm and there is a big difference. In addition, as shown in Figure 13c, even if the body does not deposit fat on the clavicle area may have a concave neck upper portion than the clavicle.

Based on the form of the neck point described above, the front position setting method of the neck point according to the embodiment of the present invention determines the x coordinate of the neck point as the middle of the x coordinate of the left and right neck points. At this time, the left and right neck points are defined as the most concave points in the front silhouette line between the height of the axillary point and the height of the head fixation point.

In addition, before setting the height of the neck point, it is determined whether or not there is a possibility of body shape. In the embodiment of the present invention, the bust circumference / key 'obesity degree reflecting the upper body circumference is used for this determination, and if this value belongs to the low body weight, it is determined that there is no possibility of a frontal fat body shape. If you belong to more than normal weight, I think there is a possibility of body fat. Here, the reason for using the 'breast girth / height' obesity is that the neck is more affected by the upper body obesity. According to this 'breast circumference / height' obesity degree, set the neck concave point to the neck point at low weight, and if it is over the normal weight, apply the same method as the method of designating the neck point after putting the neck chain around the neck at the time of direct measurement. Set the neck point.

Thus, as shown in Figure 17, the height setting method of the neck point in accordance with an embodiment of the present invention uses the cross-sectional polymerization degree of the coronal plane (xy plane) in the neck in order to create a neckline in the three-dimensional data. First, the cross-sections cut in the xy plane of the human body data between the neck point and the neck point described above are made 5 mm apart. Then, find the pit points of the neckline in each section and connect these points with a Bezier spline curve (BSpline) to create a natural neckline. Accordingly, the point located in the center of the neck while being on the neckline is set as the front neck.

18 is a view for explaining a method of setting the back and forth points of the measuring point according to an embodiment of the present invention.

Neck point of the measuring point according to an embodiment of the present invention has a correlation with the above-described difference in the height of the neck point, in particular, the highest angle is the angle associated with the neck, as shown in Table 5 below, The correlation was highest in the order of neck backward angle, back angle of neck angle, average angle of front and back of neck, angle of neck angle and neck angle.

In addition, in order to know the difference between the bowed neck, common neck, and the neck according to the neck back angle, the results of one-way batch analysis and Duncan test for the difference in the height of the neck and neck back are shown in Table 5. As shown in Table 6 and Fig. 18, at the significance level of 0.05, the flipped neck differs from other common trees and lean trees, and there is no significant difference between ordinary trees and lean trees, and the lean tree has a higher height difference than that of ordinary trees. The height difference between the neck and the back of the neck becomes greater as you go to the tree.

Accordingly, the method for setting the neck back point according to the embodiment of the present invention is based on the highest correlation between the neck back angle and the neck side back angle described above. Set the back point by using. Referring to FIG. 15, the angle between the lateral and posterior neck lines according to the neck back angle = 90.598 + (neck back angle × 0.461) was obtained by substituting the neck back angle of the subject and obtaining the 'Neck Side Back angle'. The point satisfying the Neck Side Back angle 'may be set as the neck back point.

Finally, by the regression equation of 'Neck Side Back angle' according to the back neck angle, the back neck angle affects the angle between the neck and back neck, and as the neck back angle increases, the angle between the neck and back neck becomes larger. have.

19 is a view for explaining a method for setting the shield cartilage below the point of the measuring point according to an embodiment of the present invention.

Referring to FIG. 19, the lower point of the shield cartilage among the measuring points according to the embodiment of the present invention uses the correlation between the aforementioned neck point (FNeck) and the jaw inner pt, which is where the neck is bent from the jaw. Point located between FNeck and jaw inner pt, and set so that the distance between FNack and jaw inner pt is divided by 6: 4. do. In other words, the thyroid pt is the distance between the neck and jaw inner pt in a straight line between the neck and the jaw inner pt. Is the furthest point toward the chin from the division by 6: 4.

20 to 22 are views for explaining a method for setting the shoulder point of the measurement point according to an embodiment of the present invention.

Among the measuring points according to the embodiment of the present invention, the shoulder point is a position bisecting the width of the upper arm when viewed from the front, and the position splitting the width of the upper arm when viewed from the side, or at the line and the neck point drawn forward along the width of the shoulder bone peak. It is the point where it meets the line connecting the clavicle peak.

Referring to FIG. 20, the height setting method of the shoulder point is set by using the correlation between the shoulder line protrusion point and the arm shoulder convex point. That is, as shown in the left figure of FIG. 20, first, the shoulder line protrusion point SP2 is found. The shoulder line point is the first point that meets the shoulder line when drawing a straight line from the side point to the shoulder. Then find the shoulder point of convexity. The shoulder shoulder convex point is the point where the vertical distance between the side line (Side Nack point) and the outermost point (point A) at the arm circumference is the longest (SP3, Cross SP) among the front silhouette points near the shoulder. .

Thereafter, as shown in the right figure of FIG. 20, a straight line parallel to the arm axis while passing through a shoulder line and a shoulder shoulder convex point P2, which is connected to the side Nack point and the shoulder line protrusion point SP2. arm line). At this time, the arm axis is set to a straight line consisting of the midpoint of the end face at the height of the axle, and the midpoint at the middle height end face of the armpit and the wrist point.

Then, find the point crossP where the two upper shoulder lines and the arm line intersect. Subsequently, when the intersection point between the cross point crossP and the armpit point line and the shoulder silhouette line is obtained, the intersection point becomes the shoulder point.

Thus, the height setting method of the shoulder point according to the present invention has the advantage that can reflect both the shape of the arm and the shape of the shoulder.

Referring to FIG. 21, as described above, after setting the height of the shoulder point, the method of setting the side position of the shoulder point is an arm thickness bisector (a FIG. 20 a) in which the arm thickness is bisected at the arm height. ) Or the silhouette point (b of FIG. 20) serving as the outermost point of the shoulder point height section.

In addition, referring to Figure 22, the method of setting the side position of the shoulder point may use the shoulder section bisector in the armed direction.

In other words, the bisection of the shoulder section in the armed direction is not divided into bilaterally by looking at the thickness of the arm when dividing the arm width in half, but by dividing the end of the shoulder section as viewed in a line perpendicular to the armed direction. Is bisected by the width of the shoulder when looking in the direction of the arm. Accordingly, the above-described method is effective when the arm is in the same direction as the shoulders, but the shoulders are different in the direction of the arm and the shoulder (the arm is starting to meet the body). When the vector is directed from the back arm fold pt to the front arm fold pt, when the vector faces the forearm, the back shoulder shape or the shoulder shape (the direction of the arm with the arm) The above-described method works well when the vector is in the form of a vector from the back arm fole pt where the body starts to meet to the front arm fold pt. Does not match. Here, the reason that the direction of the arm is different from the direction of the shoulder is because the scan posture is behind the palm of the hand, so the position is retracted and the arm is placed at the back, so that the back arm fold pt is inward. Arm fold pt) is formed outward. Therefore, it is desirable to maintain the correct shoulder with the palm toward the body during the scan.

23 is a view for explaining a method of setting the axillary front wall point of the measuring point according to an embodiment of the present invention.

Referring to FIG. 23, anterior circ and anterior midaxilla among measuring points according to an embodiment of the present invention serve as a reference for measuring anterior and posterior, and a shoulder pt. Since the correlation between the armpit point and the armpit point is used, it depends on the accuracy of the shoulder point and armpit point setting.

Accordingly, the front axillary point (the rear axle point) first sets the arm circumference line (Armscye Circ) and then the distance of the distance from the shoulder point to the front armpit point and back armpit point on the vibration line. Set it to the middle position.

24 and 25 are diagrams for describing a method for setting a zero point among measuring points according to an exemplary embodiment of the present invention.

Crop point of the measuring point according to an embodiment of the present invention is a reference point for dividing both the torso, the leg, and the leg, when the shape of the longitudinal section is divided into the front and the rear, the front is generally high and the rear is low. In some postures, the front of the back and lower abdomen is lower in the front, and vice versa in the lower back. Also, even in extreme obesity, the back of the ear is lower. Therefore, although the position of the lowest point in the end section is different, it is preferable that the lowest point be the height of the point for making the garment. The lateral position of the focal point is preferably a position that bisects the thigh thickness in consideration of the pants.

24 and 25, the method for setting the focus point among the measurement points according to the present invention has a preliminary step for recognizing the focus point. That is, the front silhouette inside the leg is made. Find the point with the highest height (y-coordinate) in the front silhouette and call this point Temp Temp.

Then, create a longitudinal cross section through the temp crotch and find the foremost point Pa in the hip height cross section. The point Pb, which is 1/3 the thickness of this section, is then found from the frontmost point Pa of the cross section of the Gluteal Fold below height. After that, make a straight line with two points, Pa and Pb. At this time, it is preferable that the z-coordinate of the height of the ridge groove is set to be 1/3 of the thickness of the ridge groove point.

Afterwards, the vertical distance from the straight line is the farthest point among the points in front of the vertical section, and this point is called 'front point'. Also, set the 'back point' in the same way as the front. However, in the case of poor scan of the back end section, the back end point may be set on the cut section by moving the end section slightly on the x-axis. At this time, the amount of movement is preferably 10mm because the maximum range that is not scanned in the rear center is 10mm.

26 and 28 are diagrams for describing a method of setting a waist side point among measuring points according to an exemplary embodiment of the present invention.

According to the embodiment of the present invention, the waist point is defined as a waist height when viewed from the front, but when observing the waist shape, there may be a number of body types in which the concave position cannot be found.

Lateral waist (lateral waist) according to an embodiment of the present invention, as shown in Figure 26, uses three points to determine the front type of the waist, the upper reference point (upPt), the lower reference point (downPt), We use the farthest point (concavePt) from these two points. As described above, when these three points are determined, the body shape can be determined as shown in FIG. 27.

In other words, the whole waist shape is divided into Y, H, and A types using SideAngle. If the SideAngle is larger than 90 degrees, the Y type is greater than 90 degrees. Judging by the sentence. Afterwards, the "upper back shape" is divided into X and H types using UpAngle. If UpAngle is less than 90 degrees, it is determined as X type, and if it is greater than or equal to 90, it is determined as H type. Examples of such a waist front type are shown in FIG. 28. After dividing the front type of the waist, the waist concave point (concaveP) can be defined as the waist point only when the 'upper back shape' is X type.

Here, the reason for dividing the frontal type of the waist is to know if there is a waist concave point, so the criterion should be set so as to reduce the risk of finding the concave point in the non-waist position as much as possible. For this reason, the heights of the upper and lower sides for determining the frontal type of the waist are different for women and men.

In other words, for women, the upper reference point (upPt) is the torso silhouette point at the height of the lower breast, and the reason is that if the reference is the height of the bust point or the bust point, the lower part of the breast This concave Pt is a lot of body shape, because the height point under the breast is likely to be mistaken as the waist point. The lower reference point (downPt) is determined by considering the statistical range where the waist is located between the lower breast point and the hip height. The reason for this is that if the hip height is used, the part tightened by the waistband under the measurement suit is likely to be mistaken as a concavePt.

For men, the upper reference point (upPt) is the axillary torso silhouette point, because it is difficult for a man to know the bottom of the breast and the position under the breast is hardly concave. The lower reference point (downPt) is determined by considering the statistical range where the waist is located between the neck back point and the height of the crotch.

Based on the above, the method of setting the lateral waist of the X-type waist sets the concavePt as the lateral point, even though the body determined as the X-type may have body types other than the waist lateral point. . This is because the definition of the direct measurement waist point is the waist concave point when viewed from the front, but in practice, the measurer sets it to a more appropriate position below that if the waist concave point is determined to be too high. The judgment of such a measurer is not based on the shape feature, it is desirable to set the average height of the waist point subjectively. Therefore, in the embodiment of the present invention, the height range in which the waist concave point (concavePt) can be viewed as the waist side point is determined, and when the waist concave point (concavePt) is out of this range, it is determined as the H type rather than the X type.

In addition, the above method of setting the waist point of the H type waist (body without waist concave point) may determine the bottom part of the rib as the waist point in the direct measurement method when the H type waist cannot be found at the front of the body. Also, the elbow height may be defined as the waist point.

In addition, the above-described waist point setting method of the H-type waist can be set by using an average value of the ratio with respect to the different height or distance of the waist point in the case of a body shape in which there is no constricted portion on the waist front. In this case, the average of the waist point and the waist point and the distance between the neck and the point of the neck (= torso distance) of the waist point is applied by applying an average of the two points. You can see that it is set closer.

The results can be expressed as shown in Table 7, which appears to be set closer to the waist when applying the ratio of the distance between the waist and the hip to the distance between the neck and the hip (= trunk). . Therefore, in the embodiment of the present invention, in the case of the H-type waist, it is preferable to set the waist point by a method of applying a ratio of (waist point- 샅 height) / (back-point- 샅 height).

29 is a view for explaining a method of setting a discharge protrusion point among measuring points according to an embodiment of the present invention.

Referring to FIG. 29, the abdomen point Pt among the measuring points according to the embodiment of the present invention is the maximum protruding point Pt protruding between the waist and the height of the waist, as shown in FIG. 29A. Although it can be set precisely in this clear body shape, as shown in b of FIG. 29, it is difficult to find a particularly protruding point, or as shown in c and d of FIG. 29, the most protruding point in a body in which a part other than the abdomen is more protruded. It's hard to find, and if it's not so clear, you have to set it subjectively.

Based on this, the method of setting the outgoing point of the measuring point according to an embodiment of the present invention as a protruding point (Protruding Pt) protruding from the front of the side silhouette, but for the neck-point- 샅 height distance (= trunk distance) It is advisable to obtain the statistics of pear height-to-height ratio (= (protrusion point-to-height) / (back-to-neck height) so that Abdomen Pt is within a certain range above and below the mean. Do. Here, the statistics on the position ratio of the body distance of the abdomen Pt can be expressed as shown in Table 8.
