4 to 7 are diagrams for explaining a process of calculating the separation degree for each posture evaluation item according to an embodiment of the present invention.

For example, if a teacher who is a measurer wants to evaluate a student's posture by using a PC 200 having a posture evaluation system installed thereon, the teacher first connects the camera 100 and the PC 200 and then leveles the camera 100 horizontally. Fit. Then, the attitude evaluation system installed in the PC 200 is executed. In the initial screen configuration as shown in FIG. 3, the teacher inputs the distance between the subject and the camera 100 through the distance input unit 140. If the system lacks the distance input unit 140, the system may be maintained by keeping the distance between the subject and the camera 100 as much as the recommended distance when using the system.

After inputting the distance, the teacher inputs student personal information through the personal information input unit 130. This is also optional. After entering the personal information, the teacher will place the student at a predetermined point and take a proper posture for each posture evaluation item. For example, when the posture evaluation is performed on the 'shoulder tilting', the camera 100 is stared at the front, and instructs the user to take a picture in a posture. When the student takes the correct posture, the teacher selects, for example, 'shoulder inclination' of the posture evaluation item input unit 110 on the display screen shown in FIG. 3 and clicks the measurement button or the 'capture' button. Then, an image as shown in FIG. 4A is displayed on the posture evaluation display window A. FIG.

In this state, the teacher can obtain the results of the posture evaluation on the degree of spinal flexion as well as the shoulder tilt of a student.

On the other hand, if the posture evaluation item is 'pelvic tilt', the teacher places the thumb of both hands on his upper pelvis (upper corner of the pelvis) and photographs the front face. Figure 4 (c) shows only the image of the waist portion with the thumb on the superior iliac pole. In the screen image of FIG. 4C, when the teacher marks the thumb as the posture evaluation points a and b, the distance calculation unit 120 uses the position coordinates of the posture evaluation point and the distance information between the pixels to posture evaluation point. The distance (e) between the extension line (d) connecting the fields (a, b) and the horizontal reference line (c) is calculated and transmitted to the evaluation result display unit 125. The evaluation result display unit 125 compares the calculated separation degree with the reference value for each posture evaluation item and displays the posture evaluation result in any one of normal, mild, and serious. This allows the teacher to obtain a posture evaluation result for the pelvic tilt.

This allows the teacher to obtain a posture evaluation result for cervical tilt.

6 (a) is a captured image for evaluating 'leg flexion'. The purpose of the leg flexion assessment is to examine whether the leg is bent or outward or skewed. In the screen image of FIG. 6A, when the teacher marks the center of the knee as the posture evaluation point i and marks the right and left edges of the leg as the posture evaluation points h and j, the separation degree calculator The reference numeral 120 calculates a separation degree (difference between m and n) between the posture evaluation points h, i, i, and j using the position coordinates of the posture evaluation point and the distance information between the pixels, and transmits them to the evaluation result display unit 125. . The evaluation result display unit 125 compares the calculated separation degree with the reference value for each posture evaluation item and displays the posture evaluation result in any one of normal, mild, and serious. This allows the teacher to acquire the results of the posture evaluation of the subject's leg flexion.

6B is a captured image for evaluating 'lean body tilt'. The purpose of this upper body inclination evaluation is to examine the degree of curvature of the back. In the screen image of FIG. 6 (b), the teacher marks the center of the shoulder as the posture evaluation point i, and also the edge of the chest area as the posture evaluation point h, and the edge of the dorsal muscle part of the dorsal region. Marking the posture evaluation point j, the distance calculation unit 120 calculates the distance between the posture evaluation points h and i, i and j (the difference between m and n) using the position coordinates of the posture evaluation point and the distance information between pixels. The calculation is then transferred to the evaluation result display unit 125. In this regard, the evaluation result display unit 125 compares the calculated separation degree with a reference value for each posture evaluation item and displays the posture evaluation result in any one of normal, mild, and serious states, and thus the teacher displays the detailed slope of the subject. The attitude evaluation result can be obtained.

Finally, (a) and (b) of FIG. 7 are descriptions for evaluating 'before and after the pelvic tilt', (a) is a view for showing the shape of the finger of the subject, and (b) is a captured image. The purpose of evaluating the pelvic tilt before and after is to examine whether the pelvis is tilted back and forth. For this test, the teacher asks the student as a subject to take a side view by placing the palm of his hand against the superior iliac spine as shown in (a). In the screen image of FIG. 7 (b), the teacher marks the thumb and middle finger as the posture evaluation points a and b. Accordingly, the separation degree calculator 120 uses the positional coordinates of the posture evaluation point and the distance information between pixels, and the separation distance e between the extension line d connecting the posture evaluation points a and b and the vertical reference line c. Calculate and pass to the evaluation result display unit 125. The evaluation result display unit 125 compares the calculated separation degree with the reference value for each posture evaluation item and displays the posture evaluation result in any one of normal, mild, and serious.
