Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an internal configuration of an obesity / body evaluation system according to an embodiment of the present invention. As shown in FIG. 1, the obesity / body evaluation system 100 according to the present embodiment includes a storage unit 110, an image input unit 120, a virtual marker generation unit 130, and a body size calculation unit 140. And obesity / body evaluation data generation unit 150.

The storage unit 110 stores and maintains standard body dimensions. Here, the storage unit 110 may store standard body sizes classified according to at least one of sex, age, and body parts. For example, pre-determined standard body dimensions such as gender of men and women, ages in their 20s and 60s, and body parts such as chest, waist, thigh, and calf, may be stored in the storage 110. Can be. In addition, standard body sizes, categorized by race or country, may also be used. In other words, in the case of Koreans, the standard body size for Koreans and in the case of Americans, the standard body size for Americans can be stored, and appropriate standard body size can be used according to nationality.

The image input unit 120 receives an image captured by the subject. In this case, the image captured by the subject may receive an image captured by the subject through a network such as a web or may be directly connected to a camera to receive an image of the subject measured by the camera. For example, the input image may be directly connected to a photographing means such as a web camera, a camcorder, a stereo camera, or connected to a device such as a computer storage device or a USB memory. In addition, when the image is input through the network, the result may also be provided to the subject through the network.

In this case, the virtual marker generator 130 may generate a virtual marker at a position selected from the measurer through a function provided to the measurer in the interface unit.

Also, in another embodiment, the virtual marker generator 130 may generate a virtual marker by searching for a specific position among body parts of the subject by analyzing the input image. Since a variety of methods are already known for finding feature points in the human body, detailed descriptions thereof will be omitted.

Body circumference calculation unit 140 calculates the body circumference dimension of the subject through the position of the generated virtual marker. In this case, as an example, the distance between the virtual markers may be used to calculate the body circumference of the subject. The input image may include an image in which the front and side surfaces of the subject are photographed, and the body size calculation unit 140 includes a plurality of virtual markers and side surfaces of the subject measured in the image of the front surface of the subject. The body circumference dimension of the body part of the subject may be calculated through the plurality of virtual markers generated from the captured image. For example, the virtual marker created in the "under the right armpit" position and the "under the left armpit" position in the image of the front part of the subject, and the "left papilla" position and the "left nipple" position in the image of the subject's left side. Virtual elliptic circumferences can be calculated from the virtual markers created at the "back-back" position parallel to the left nipple.

That is, when the "chest circumference" of a woman in her twenties is calculated, the calculated body circumference dimension can be compared with a pre-stored standard size dimension for the "bust circumference" of a woman in her twenties. The obesity / body evaluation data generation unit 150 may generate the obesity / body evaluation data according to the score range corresponding to the calculated body circumference dimension among a plurality of selected score ranges by adding or subtracting a predetermined value to the standard body size. Can be.

In addition, in order to calculate and evaluate the age corresponding to the measurement date, the age of the subject may be calculated based on the date of birth and the date of measurement of the subject. For example, even if the current age of the subject is 32 years old, when the age of the measurement is 28 years old, it can be compared with the standard body size of the 20s.

In addition, the body circumference dimension calculation unit 140 may further calculate the body length dimension of the subject through the position of the generated virtual marker, and the obesity / body evaluation data generation unit 150 may measure the body length dimension and the standard body size. Can be compared to further generate data as obesity / shape assessment data. For example, the obesity / body evaluation system 100 further stores a standard body size for a length such as “head vertical length” in the storage unit 110, and the position of the virtual marker in the body size calculation unit 140. When calculating the "head vertical length" of the subject through, the obesity / body shape evaluation data generation unit 150 compares the calculated "head vertical length" and the "head vertical length" of the stored standard body size with the obesity / body shape Further evaluation data can be generated. This body length dimension may be equally applied to other dimensions such as "height", "arm length", "leg length", and the like.

2 is an example of an image input to the obesity / body evaluation system according to an embodiment of the present invention. As shown in FIG. 2, the size of the actual background entered into the frame 210 of the input image may be preset. For example, the photographing means is fixed to the frame 210 of the image to match the basic board 220 having a known size, and the subject 230 is placed in front of the basic board 220 at a predetermined position. You can shoot. In this case, when the photographing means is fixed to match the frame 210 of the image and the base board 220, the base board 220 may be removed and the subject 230 may be photographed. One embodiment of the present invention can set the length of the horizontal and vertical corresponding to the size of the actual background to the value defined by the measurer, and when using the base board to make the reference board arbitrarily the size of the reference board to the size of the actual background Can be set to

3 is an example of a basic board used for capturing an image input to an obesity / body evaluation system according to an embodiment of the present invention. As described with reference to FIG. 1, the virtual marker generator 130 of the obesity / body evaluation system 100 described with reference to FIG. 1 uses an image of an input image using a size of an actual background and a resolution of an input image. The distance per pixel of can be calculated. In this case, the lengths of the horizontal (1.20m) and the vertical (2.00m) of the basic board 301 corresponding to the actual background shown in FIG. 3 are divided by the number of pixels of the input image, that is, the resolution (1600 * 1200). The distance can be calculated.

4 is an example of generating a virtual marker on the front of the subject of the image input to the obesity / body evaluation system according to an embodiment of the present invention. 4 illustrates an example in which virtual markers are generated at a plurality of positions in an image of a front surface of a subject to be photographed. At this time, the information on each virtual marker generated is shown in Table 1 below.

FIG. 5 illustrates an example of generating a virtual marker on a side of a subject of an image input into an obesity / body evaluation system according to an embodiment of the present invention. 5 illustrates an example in which virtual markers are generated at a plurality of positions in an image in which a left side of a subject is photographed. At this time, the information on each generated virtual marker is shown in Table 2 below.

6 is an example for explaining a method of calculating the body circumference dimension through the virtual marker in the obesity / body shape evaluation system according to an embodiment of the present invention. 6 shows four virtual markers needed to measure the "hip circumference". That is, in FIG. 6, the virtual marker [OA # 7] 611, the virtual marker [OA # 8] 612 in Table 1 of FIG. 4, and the virtual marker [OL # 7] 621 in Table 2 of FIG. 5. , Four markers of the virtual marker [OL # 8] 622 are shown. That is, the obesity / body shape evaluation system according to the present embodiment has a long axis as the distance between the virtual markers [OA # 7] 611 and the virtual markers [OA # 8] 612 through positions for each of the four markers. The circumference of the virtual ellipse which shortens the distance between the virtual marker [OL # 7] 621 and the virtual marker [OL # 8] 622 can be calculated as the body circumferential dimension as the "hip circumference". Since the method of calculating the circumference of the ellipse through the length of the long axis and the length of the short axis is already known, a detailed description thereof will be omitted.

7 is a table showing an example of a standard body size used in the obesity / body shape evaluation system according to an embodiment of the present invention. Table 700 shows standard body dimensions that can be pre-determined by gender, age and body part (measurement items) and can be stored in the obesity / body evaluation system. That is, the standard body size may be previously stored in the storage unit 110 of the obesity / body evaluation system 100 described with reference to FIG. 1 and used for comparison with the calculated body circumference size.

8 is a table showing an example of the scale used in the obesity / body evaluation system according to an embodiment of the present invention. In the table 800 shown in FIG. 8, "M" represents the body circumferential dimension calculated for the corresponding body part of the subject, and each% value is a value for adding or subtracting each% value to the standard body type index by age group / gender. It may mean. This table 800 shows an example of using a seven-point scale that determines "scale"-"normal"-"obesity" as seven values. For example, if the calculated body circumference is within the range of the maximum value minus the value "± 5%" of the standard body shape index, the body part corresponding to the calculated body circumference is "7" on the 7-point scale. It may correspond to the zero point which is a measure of "normal". In addition, when the calculated body circumference is included in the range exceeding the value "+ 20%" in the standard body index, the body part may correspond to four points of the "obesity" of the seven-point scale .

9 is a table illustrating an example of a criterion for evaluating a body shape through a drop dimension in an obesity / body evaluation system according to an embodiment of the present invention. In this case, the drop dimension may mean a value obtained by subtracting “thigh circumference” from “hip circumference”. As shown in FIG. 9, the first table 910 shows a body shape according to the age group of a droop, and the second table 920 shows a body shape according to the age group of a man. In this case, "D" shown in the first table 910 and the second table 920 may mean its own drop dimension. That is, in the case of a woman in her 20s with a drop dimension of "80", it may be determined that the woman has a normal standard body type of N-type as shown in the first table 910. As described above, the obesity / body evaluation system according to the present embodiment may generate comprehensive obesity / body shape evaluation data using drop size, height, and weight based on the body circumference size and provide the data to the subject. For example, Table 3 below shows an example of the criteria for determination by height available in the obesity / body evaluation system (in millimeters), and Table 4 shows an example of the criteria for determining body mass index available in the obesity / body evaluation system. Represent each.

That is, the obesity / body type evaluation system can receive the height and weight of the subject to generate more comprehensive obesity / body type evaluation data.

10 is a table showing an example of obesity / body shape evaluation data generated by the obesity / body shape evaluation system according to an embodiment of the present invention. The table 1000 shown in FIG. 10 shows overall results such as circumference determination comparing body circumference dimensions and standard body dimensions, height determination through extension, "BMI" determination as a body mass index, and body shape determination using a drop dimension. .

Figure 11 is an example showing the body circumference dimension and body length dimension that can be additionally measured in the obesity / body evaluation system according to an embodiment of the present invention. That is, in addition to the above-described body part, a virtual marker may be additionally generated in addition to the required body part to measure the circumference or length of the desired body part. In the example of FIG. 11, the virtual marker is created in the "head point" and the "jaw end point", respectively, in order to calculate the "head vertical length". That is, the "vertical head length" may be calculated through the distance between the virtual markers of the "head point" and the "chin point". In addition, the example of FIG. 11 shows body parts that can be added as needed, such as "neck circumference", "ankle circumference", and "upper circumference". In this case, the additionally measured site in the example of Figure 11 is shown in Table 5 below.

In this case, as described above, a virtual marker may be generated through front and side images of the subject, and body circumferential dimensions such as ankle circumference and upper arm circumference may be calculated through the position of the virtual marker.

12 is a table showing an example of a standard body size that can be additionally stored in one embodiment of the present invention. Table 1200 shown in FIG. 12 shows standard body size by gender and age for "head vertical length", ankle circumference "and" upper circumference "added in FIG.

FIG. 13 is an example illustrating the multiple ratio of the head vertical length to the total height using the calculated head vertical length. That is, in the example of FIG. 13, the model of 7.6 is shown on the scale which shows how much is the total height when the head vertical length is 1. Such ratio information may also be included in the overall result described with reference to FIG. 10.

14 is a table showing another example of obesity / body shape evaluation data generated by the obesity / body shape evaluation system according to an embodiment of the present invention. The table 1400 shown in FIG. 14 shows circumferential determination results such as "head vertical length", "ankle circumference", and "upper circumference" and a torso determination result which is a ratio of head length and height (height). These determination results may be included together in the overall result described with reference to FIG. 10.

That is, FIGS. 11 to 14 show that various body parts may be additionally measured as necessary in addition to the body parts described above. In addition, in the above-described description, only the differences according to gender / age band are used in the above description, but differences according to heights may be further applied. That is, the dimensions of each body part according to height may be further used for the evaluation of obesity / body shape. For example, Table 6 below shows the golden ratio of each body part according to height, and Table 7 shows the weight and dimensions according to the height corresponding to the golden ratio.

15 is a flowchart illustrating a method for evaluating obesity / body shape according to an embodiment of the present invention. The obesity / body evaluation method according to the present embodiment may be performed by the obesity / body evaluation system 100 described with reference to FIG. 1. In FIG. 15, the obesity / body evaluation method will be described by explaining a process in which each step is performed by the obesity / body evaluation system 100.

In step 1510, the obesity / body evaluation system 100 stores and maintains a standard body size. Here, the obesity / body shape evaluation system 100 may store the standard body size classified according to at least one of sex, age, body parts. For example, the pre-determined body size, such as gender of men and women, ages 20s to 60s, and body parts such as chest, waist, thigh, and calf circumferences, obesity / body evaluation system (100) Can be stored in. In addition, standard body sizes, categorized by race or country, may also be used. In other words, in the case of Koreans, the standard body size for Koreans and in the case of Americans, the standard body size for Americans can be stored, and appropriate standard body size can be used according to nationality. This step 1510 may be a preprocessing step that continues to use the standard body size stored and maintained, rather than being performed every time the obesity / body shape is evaluated.

In operation 1520, the obesity / body evaluation system 100 receives a photographed image of the subject. In this case, the image captured by the subject may receive an image captured by the subject through a network such as a web or may be directly connected to a camera to receive an image of the subject measured by the camera. For example, the input image may be directly connected to a photographing means such as a web camera, a camcorder, a stereo camera, or connected to a device such as a computer storage device or a USB memory. In addition, when the image is input through the network, the result may also be provided to the subject through the network.

In operation 1530, the obesity / body evaluation system 100 generates a virtual marker at a plurality of positions of the input image. In this case, the plurality of positions may include a specific position among body parts of the subject measured in the input image. For example, the virtual marker may be generated at the most protruding portion of the right waist of the subject or the most protruding portion of the left pelvis.

In order to generate such a virtual marker, the obesity / body evaluation system 100 may further include an interface unit (not shown) that provides a function for receiving a plurality of locations to the measurer. In this case, the obesity / body evaluation system 100 may generate a virtual marker at a position selected from the measurer through a function provided to the measurer in the interface unit.

In another embodiment, the obesity / body evaluation system 100 may generate a virtual marker by searching for a specific position among body parts of the subject by analyzing the input image. Since a variety of methods are already known for finding feature points in the human body, detailed descriptions thereof will be omitted.

In step 1540, the obesity / body shape evaluation system 100 calculates the body size of the subject through the position of the generated virtual marker. In this case, as an example, the distance between the virtual markers may be used to calculate the body circumference of the subject. The input image may include an image of the front side and the side of the subject, and the obesity / body evaluation system 100 may include a plurality of virtual markers and side surfaces of the subject. The body circumference dimension of the body part of the subject may be calculated through the plurality of virtual markers generated from the captured image. For example, the virtual marker created in the "under the right armpit" position and the "under the left armpit" position in the image of the front part of the subject, and the "left papilla" position and the "left nipple" position in the image of the subject's left side. Virtual elliptic circumferences can be calculated from the virtual markers created at the "back-back" position parallel to the left nipple.

To this end, the obesity / body evaluation system 100 may calculate the distance per pixel of the input image by using the size of the actual background and the resolution of the input image that have entered the frame of the input image, and use the distance per pixel. The distance between the plurality of virtual markers may be calculated from each of the front and side surfaces thereof, and the body circumference dimension may be calculated based on the calculated distance. In other words, in the above-described example, the distance between the virtual markers generated at the "lower armpit" position and the "lower armpit" position, respectively, and the "left nipple" position and the "left nipple" in parallel with the left nipple in the image of the subject. Using the distance between the virtual markers respectively created at the "back back" position, the virtual elliptic circumference can be calculated as the body circumference relative to the "chest circumference".

In operation 1550, the obesity / body evaluation system 100 may generate the obesity / body evaluation data by comparing the calculated body circumference dimension with the standard body size. In this case, the obesity / body evaluation system 100 corresponds to at least one of body parts corresponding to the sex, age, and calculated body circumference of the subject when the standard body size is classified according to gender, age, or body part. Obesity / body shape evaluation data can be generated by comparing the standard body size and the calculated body circumference size. That is, when the "chest circumference" of a woman in her 20s is calculated, the calculated body circumference may be compared with a pre-stored standard size dimension for the "chest circumference" of a woman in her 20s. The obesity / body evaluation system 100 may generate the obesity / body evaluation data according to a score range corresponding to a calculated body circumference dimension among a plurality of selected score ranges by adding or subtracting a predetermined value to a standard body size. .

In addition, in order to calculate and evaluate the age corresponding to the measurement date, the age of the subject may be calculated based on the date of birth and the date of measurement of the subject. For example, even if the current age of the subject is 32 years old, when the age of the measurement is 28 years old, it can be compared with the standard body size of the 20s.

In addition, the obesity / body shape evaluation system 100 can further calculate the body length dimension of the subject through the position of the generated virtual marker, and compares the body length dimension and the standard body size data as the obesity / body shape evaluation data. Can produce more. For example, the obesity / body evaluation system 100 further stores standard body dimensions for lengths such as “head vertical length” and calculates the “head vertical length” of the subject based on the position of the virtual marker. By comparing the "head vertical length" with the "head vertical length" of the stored standard body dimensions, it is possible to further generate obesity / body evaluation data. This body length dimension may be equally applied to other dimensions such as "height", "arm length", "leg length", and the like.
