A method for recognizing the acupuncture point using the above-described user apparatus 100 according to an embodiment of the present invention will now be described. 2 is a flowchart illustrating a method for recognizing the acupressure point according to an embodiment of the present invention. FIGS. 3 to 17 are examples of a screen for explaining a method for recognizing the acupuncture point according to the embodiment of the present invention.

2, in response to an input from the user through the input unit 120 or the display unit 130, the control unit 150 photographs the hand of a target to be searched for the myocardial point through the camera unit 110 in step S110, (Hereinafter abbreviated as "hand image"). Here, the hand image includes the hand and its surrounding background.

Next, the controller 150 specifies the skin region and the background region from the image including the hand in step S120. An example of such a screen is shown in Fig. 3 (a) shows a hand image. From the hand image, as shown in FIG. 3 (b), only the skin region can be detected to specify the skin region. When the skin region is specified, all remaining regions are specified as background regions. In more detail, in step S120, the hand image obtained by the controller 150 is one frame, and the hand image basically uses the RGB coordinate system. First, the controller 150 converts the pixel values of all the pixels of the hand image into the HSV coordinate system according to the following equation (1) in the RGB coordinate system.

The HSV coordinate system transforms the RGB coordinate system into Hue, Saturation, and Value, and the color ranges from 0 to 360 from red to purple. Saturation is a form in which the degree of intensity of each color is expressed in the range of 0 to 100, and the closer to 0, the darker the closer to 100 from achromatic. Brightness is a form in which the brightness of a color is expressed in a range of 0 to 100, and 0 is a blackness, and indicates the degree of brightness from 100 to white. Using the HSV coordinate system, only the desired color can be detected in the image. Since it searches for colors included in a range other than a single color, it shows a high detection rate even in the illuminance and noise environments. In addition, since all people commonly include red color, it is possible to detect skin regardless of skin color of yellow, white and black, which is advantageous for detecting skin area than RGB coordinate system. Accordingly, the controller 150 determines a hand region, which is a skin region, in the hand image by using a preset HSV value for detecting a skin region in a predetermined color, i.e., an HSV coordinate system, through the hand image transformed from the HSV coordinate system in the RGB coordinate system do.

Next, when the skin region is specified, the controller 150 extracts the contour point 40 of the hand from the skin region, i.e., the hand region, in step S130.

An example of such a screen is shown in Fig. As shown, the contour point 40 is a plurality of points that form the periphery of the hand region. The control unit 150 can extract the contour point 40 of the hand.

The control unit 130 gradually increases the range starting from any one point existing in the skin region, i.e., the hand region, and locates a point located at the outer periphery of the eight rooms, and finds the outer point immediately before leaving the hand region Repeatedly, contour points can be obtained. That is, the control unit 130 extracts a point (pixel) located on the outer periphery of the eight points of the point starting from one point (pixel) of the skin region (hand region) Points are extracted. In this way, the extraction of the outermost point is repeated until the outermost point in the entire skin area is extracted, and then the outermost point in the skin area is determined as the contour point.

The contour point derivation method will be described in more detail with reference to FIG. FIG. 5 shows a part of a hand image in pixel units, and shows pixels from pixel coordinates 701 and 678 to 709 and 686. FIG. The pixels denoted by P1 to P7 denote pixels of the skin region, i.e., a hand region, and portions denoted by E denote pixels of the background region. The control unit 130 searches for an outer edge point and increases the gradual range until a pixel E of the background area starts from any one point (pixel) P1 existing in the skin area, i.e., the hand area. For example, after P2 in the outer 8 room of P1 is found, the range is gradually increased in the order of P1 → P2 → P3 → P4 → P5 → P6 → P7 by finding P3 located in 8 rooms of each of the 8 P2 When a point (pixel) of the background area comes out, the pixel immediately before the background area is determined as the contour point.

Next, the control unit 150 extracts a first feature point that is a point located on the fingertip, that is, a fingertip point in step S140. To this end, the controller 150 first obtains a polygon having a maximum area of a polygon connecting a plurality of selected points by selecting a plurality of points out of the previously obtained contour points 40, and derives the vertices of the obtained polygon. In order for the polygon formed by connecting the contour points 40 to have the maximum area, all of the contour points 40 must be included in the polygon. The operation of the controller 150 will be described in more detail with reference to FIG.

(i) As shown in (l), (m) and (n) of FIG. 6, a plurality of points out of the contour points 40 are selected to form a polygon connecting the selected plurality of points.

(ii) As shown in Figs. 6 (1), 6 (m) and 6 (n), the area of the formed polygon is found.

(iii) As shown in FIGS. 6 (1), 6 (m) and 6 (n), the selection of a plurality of points is changed until the area of the polygon becomes the maximum, Repeat.

(iv) As shown in FIG. 6 (n), when the polygon having the largest area is obtained, the vertex of the polygon and the coordinates of the vertex are derived.

Then, the control unit 150 selects one vertex corresponding to one of the vertexes of the polygon according to a preset rule using the vertex coordinates of the polygon (i.e., the vertex coordinates of the vertex of the polygon) That is, a first feature point. The operation of the controller 150 will be described in more detail as follows.

(A) First, the control unit 150 obtains a plurality of vertexes having a Y value of the coordinates (X, Y) of the vertexes of the polygon less than the predetermined value y1, assuming that the finger is directed upward of the hand image . Assuming that the finger is pointing upward of the hand image, the vertices positioned at the fingertip will have a smaller Y value than the rest vertices. Accordingly, the controller 150 first selects some of the plurality of vertices based on the Y value of the vertex coordinates (X, Y) (i.e., the predetermined value = y1). An example of such a screen is shown in Fig. 8 (j). B, C, D, E, F (x, y) of the vertexes of the vertices of the polygon having the Y value of less than the predetermined value y1 as shown in Fig. 8 (j) , G, H, I, J and K were derived.

(B) Next, the control unit 150 assigns one vertex corresponding to each finger of the derived vertexes, that is, vertices A, B, C, D, E, F, G, H, I, End point, and extracts the first feature point.

The vertexes that can be fingertip points corresponding to any one finger are less than a predetermined distance from each other. For example, as shown in FIG. 7 (j), the vertices that can be fingertip points of the index are D and E, and the vertexes D and E are spaced apart from each other by a predetermined distance, that is, less than 2 cm. However, the remaining vertices are separated by more than 2 cm from vertex D or E. Therefore, the control unit 150 determines whether the vertex of the vertex has a Y value of less than a predetermined value y1 from the leftmost vertex or the rightmost vertex in a clockwise or counterclockwise direction And a vertex corresponding to each finger is derived according to the distance between the obtained vertexes. For example, referring to FIG. 7 (j), a vertex corresponding to each finger can be derived by obtaining the distance between neighboring vertexes sequentially in the clockwise direction from the leftmost vertex A. That is, the vertexes A and B are spaced apart from each other by a predetermined distance, while the vertices B and C are spaced apart from each other by a predetermined distance, and the vertexes C and D are spaced apart from each other by a predetermined distance. Therefore, it can be seen that the vertices B and C correspond to the thumb. Similarly, the vertexes C and D were spaced apart from each other by a predetermined distance, while the vertices D and E were spaced apart from each other by a predetermined distance, and the vertexes E and F were spaced apart from each other by a predetermined distance. Therefore, it can be seen that the vertexes D and E correspond to the index finger. Further, it can be seen that the vertexes E and F are spaced apart from each other by a predetermined distance, and the vertexes F and G are spaced apart from each other by a predetermined distance. Therefore, it can be seen that the vertex F corresponds to the stop. The vertexes F and G are spaced apart from each other by a predetermined distance, while the vertices G and H are spaced apart from each other by a predetermined distance. Further, the vertices H and I are spaced apart from each other by a predetermined distance. Therefore, it can be seen that the vertices G and H correspond to the index finger. Finally, vertexes H and I are spaced apart from each other by a predetermined distance, while vertices I and J are spaced apart from each other by a predetermined distance, and vertexes J and K are spaced apart from each other by a predetermined distance. Therefore, it can be seen that the vertices I and J correspond to the possession. Summarizing, the vertices B and C correspond to the thumb, the vertices D and E correspond to the detection, the vertex F corresponds to the stop, the vertices G and H correspond to the ring finger, and the vertices I and J correspond to the hand .

After deriving at least one vertex corresponding to each finger according to the distance between vertices, the controller 150 selects one of the vertices corresponding to each finger as a fingertip, that is, a first feature point do. That is, as shown in (k) of FIG. 7, the controller 150 selects one vertex corresponding to each finger and erases the remaining vertices. In this way, the controller 150 selects a rule for selecting one of the vertices corresponding to each finger. If there is one vertex corresponding to one of the fingers, the controller 150 selects the vertex as the fingertip, i.e., the first feature point. For example, according to (j) of FIG. 7, since the vertex corresponding to the stop is the vertex F, the vertex F becomes the first feature point. According to one embodiment, when there are a plurality of vertices corresponding to one finger, the controller 150 can select a vertex having the smallest Y value of vertex coordinates among a plurality of vertices. For example, C of the vertices B and C can be selected. According to another embodiment, when a plurality of vertices corresponding to one finger are plural, the controller 150 can select a vertex located at the center among the plurality of vertices. At this time, if the number of vertexes is odd, since the vertex located at the center is one, the vertex can be selected. For example, if there are three vertices, the second vertex can be selected. On the other hand, when the plurality of vertexes are even, the vertexes located at the center of the plurality of vertices are two. In this case, you can select a vertex close to the stop. For example, E of the vertexes D and E can be selected, and G of the vertexes G and H can be selected.

(C) If one vertex corresponding to each finger is selected, the selected vertex becomes the fingertip point, i.e., the first feature points T1, T2, T3, T4 and T5, as shown in Fig.

Next, in step S150, the controller 150 extracts a second feature point that is a fingertip point, that is, a point between fingers based on the first feature point. The point between the fingers is a point located in the bone between adjacent fingers, and is the same as V2 in Fig. At this time, the controller 150 firstly selects at least one point out of contour points between two neighboring first feature points and two first feature points, and calculates the area of the polygon connecting the selected point and the two first feature points Obtain the polygon that becomes the maximum. At this time, in order to maximize the area of the polygon, the polygon should include both contour points between two neighboring first feature points and two first feature points. Then, the controller 150 selects one of the vertexes of the largest polyhedron, and extracts the selected vertexes as the second feature point.

Hereinafter, the operation of the controller 150 will be described in detail.

(i) As shown in FIG. 9 (x), two straight lines are formed so as to penetrate the skin region in the downward direction from two neighboring fingertip points (first characteristic points), for example, T2 and T3, T2, and T3, a straight line connecting two adjacent fingertip points (e.g., T2, T3), and a straight line connecting the two adjacent fingertip points (e.g., T2, T3) .

(ii) As shown in (x), (y), and (z) in FIG. 9, at least one of the contour points in the limited area is selected and two adjacent fingertip points (first feature point) Forming a connecting polygon.

(iii) As shown in (x), (y) and (z) in FIG. 9, the area of the formed polygon is found.

(iii) As shown in (x), (y) and (z) in FIG. 9, the above-described steps (ii) and (iii) are repeated by changing the selection of the point until the area of the polygon becomes the maximum .

(iv) When a polygon having the largest area is obtained as shown in (z) of FIG. 9, the vertex of the polygon and the coordinates of the vertex are derived.

Then, the controller 150 selects one of the vertexes of the polygon according to a predefined rule using the vertex coordinates of the polygon (i.e., the pixel coordinates of the vertex of the polygon) Derive minutiae points. The operation of the controller 150 will be described in more detail as follows.

(A) First, assume that the polygon obtained for the point between the fingers is convex downward because the fingertip faces upward. Accordingly, the controller 150 obtains a plurality of vertexes whose Y values of the coordinates (X, Y) of the vertexes of the polygon are equal to or larger than the predetermined value y3.

Since the polygon for obtaining the point between the fingers has a convex shape downward, the vertexes which can be the points between the fingers to be sought will have a larger Y value than the other vertices. Accordingly, the controller 150 first selects some of the plurality of vertices based on the Y value (i.e., the predetermined value = y3) of the vertex coordinates (X, Y).

(B) Next, the controller 150 selects a vertex of one of the selected vertices as a point between fingers, and extracts the second feature point.

According to an exemplary embodiment, the controller 150 may set the vertex having the largest Y value of the pixel coordinates among the at least one vertex having the Y value of the vertex coordinates (X, Y) That is, the second feature point can be selected.

On the other hand, as in the case of obtaining the aforementioned fingertip point, when there are a plurality of vertexes that can be points between fingers, they are spaced apart from each other by less than a predetermined distance due to the shape between the fingers. Therefore, according to another embodiment, the controller 150 may calculate the distance between adjacent vertexes at a plurality of vertices having a Y value of the coordinates (X, Y) of the vertex having a predetermined value y3 or more, Can select any one of the plurality of vertexes less than the predetermined distance as the second feature point and erase the remaining vertexes.

For example, according to one embodiment, the controller 150 can select a vertex located at a center of a plurality of vertexes that are spaced apart from each other by less than a predetermined distance. At this time, if the number of vertexes is odd, since the vertex located at the center is one, the vertex can be selected. For example, if there are three vertices, the second vertex can be selected. On the other hand, when the plurality of vertexes are even, the vertexes located at the center of the plurality of vertices are two. In this case, you can select the stop and the vertex located on the far side.

(C) The control unit 150 may repeat the above-described method to derive a second feature point, which is a point between the thumb and the index, between the index and the stop, between the stop and the finger, and between the finger and the finger.

Next, in step S160, the controller 150 extracts both end points of the wrist wrinkles, that is, the third minutiae points.

10, the controller 150 sequentially measures the length of a horizontal line passing through the skin region from the top to the bottom of the skin region, and determines a predetermined section A1 in which the rate of change of the length is kept less than a predetermined value, . Depending on the shape of the hand, the rate of change of the length of the horizontal line across the skin area increases from the top to the wrist, and then the rate of change decreases from the wrist. For example, the rate of change of the lengths of L3 and L4 is smaller than the rate of change of the length of L1 and the length of L2. Therefore, the controller 150 can obtain a predetermined section A1 in which the rate of change of the length of the horizontal line is kept less than the predetermined value.

Next, as shown in FIG. 11, the controller 150 obtains the width of the skin area within the predetermined section A1, determines the position where the width of the skin area is the narrowest as the wrinkles of the wrist, To the third feature points W1 and W2. More specifically, the control unit 150 determines a right side or left side of the skin area within the predetermined section A1, and obtains the width of the skin area with respect to each of the contour points 40 on either side.

For example, when the contour point C1 on the right side of the skin region is taken as an example, the control unit 150 calculates a line segment that crosses the skin region from C1 to contour points on the other side (left side), for example, D1, D2, D3, The line segment having the shortest length is determined as the width of the skin region at the contour point C1. Here, in the case of C1, the line segment connecting C1 and D2 is the shortest line segment at the contour point C1, and the length of the segment connecting C1 and D2 may be the width of the skin region at C1. It should be noted that the width of the skin region is not a horizontal line. Similarly, in the case of C2, the line segment connecting C2 and D4 is the shortest line segment at the contour point C2, and the length of the line segment connecting C2 and D4 may be the width of the skin region at C2. In this manner, the controller 150 obtains the widths of the skin regions of the contour points on either of the left and right sides in the predetermined section A1, determines the line segment having the shortest length among the widths of the obtained skin regions as the wrinkles of the wrist , And extracts the two end points from the wrist creases as the third feature points W1 and W2.

Next, in step S170, the controller 150 extracts both sides of the finger, that is, the fourth feature point. As shown in FIG. 12, the two points S0 and S1 of the finger indicate the position S0 where the outer edge of the index finger meets the palm, and the position S1 where the outer edge of the pad and the palm meet. According to the embodiment of the present invention, the control unit 150 sets the length of a line connecting the point V2 between the detection and the stopping and the point V3 between the stop and the ring finger in the fingertip point (second characteristic point) Is determined as the width of

Then, the control unit 150 draws a horizontal line having the length of the finger (or a predetermined length longer than the finger width) determined in the detection direction at the feature point V2 between the detection and the stop. Here, the horizontal line may be a horizontal line on the hand image or a line parallel to the line connecting the third characteristic points, which are both ends of the wrinkles of the wrist. Then, the control unit 150 draws a straight line obtained by rotating the horizontal line by a predetermined angle in the downward direction (wrist direction) to the rotation axis (the imaginary line passing through the palm of the hand at the characteristic point V2 as the rotation axis). For example, a straight line is drawn in which the horizontal line is rotated by 5 degrees in the downward direction with the characteristic point V2 as the rotation axis. Accordingly, the control unit 150 determines one point S0 of both sides of the finger where a straight line rotated by 5 degrees in the downward direction and a contour point meet.

Likewise, a horizontal line having a finger width (or a predetermined length longer than the finger width) is drawn from the feature point V4 between the fingerprint and the base in the base direction. Here, the horizontal line may be a horizontal line on the hand image or a line parallel to the line connecting the third characteristic points, which are both ends of the wrinkles of the wrist. Then, the control unit 150 draws a straight line in which the horizontal line is rotated downward by a predetermined angle, e.g., Fig. 5, on the rotation axis (the imaginary line passing through the hand at the feature point V4 is the rotation axis). Then, the control unit 150 determines one of the points S1 and S2 at which the straight line and the contour point meet.

The first to fourth feature points (T1 to T5, V1 to V4, W1, W2, S0, S1) extracted according to the method described above in Fig. 13 are shown. In step S180, the controller 150 determines whether the hand is the left hand part or the right hand part, whether the hand is the hand part or the palm part in the image of the hand, and determines whether the hand is the left hand part or the right hand part based on the extracted first to fourth feature points It is possible to detect the acupoint according to whether or not the hand of the part is handed and predetermined rules. Here, whether the hand is a part may be input by the user through the input unit 120 or the display unit 130, or may be determined according to the degree of similarity between images using a hand image including a previously stored palm-shaped hand, The length of the nail and the presence of the nail can be identified and identified.
