It should be noted that the same reference numerals are used to denote the same or similar components in the drawings.

        1 is a configuration diagram of a pattern image of a light beam according to an embodiment of the present invention and a home golf simulator system using an optical sensor.

        The swing plate 110 includes a plurality of optical sensors 120, a club comparison plate 130, a light beam golf club 100, a swing information calculation unit 150, a screen golf simulation unit 160, And a display unit 170.

        The swing plate 110 swings the light ray golf club 100 as it passes over the swing plate 110 as the surface where the light ray golf club 100 swings. A golfer of a home golf simulator system using the light pattern image 140 and the optical sensor 120 of the present invention swings the light beam golf club 100 assuming that there is a virtual golf ball at the center point of the swing plate.

        The light ray golf club 100 is made of a light emitting device (not shown) coupled to the end of the gripper body and a fixed length of a golf club such as a wood or iron, and a light emitting device provided at the end of the gripper body The pattern image 140 is inspected.

        The light beam golf club 100 includes a club selection button 107 for setting a desired club, a function for wirelessly sending the set information to the swing information calculation unit, and a club display unit 108 for displaying set club information, have.

        When a golfer holding the light beam golf club 100 swings, a change in the light beam pattern image 140 is detected by five optical sensors located at the center, left, right, upper and lower sides of the swing plate 110, Allowing an electrical signal to be generated.

        In the swing plate 110 shown in FIG. 2, a club comparison plate 130 on which a club type is displayed is arranged on a line of the upper side perpendicular to the center point according to the size of a light ray pattern image for each club length.

        A central light sensor 122 is disposed at a center point of the swing floor 200 so that the golfer can recognize the golf ball as a virtual golf ball.

        The upper optical sensor 121 and the lower optical sensor 123 are vertically arranged with respect to the central optical sensor 122 and the left optical sensor 120 and the right optical sensor 124 are further arranged with four optical sensors horizontally The distance between the upper light sensor 121 and the lower light sensor 123 is shorter than the vertical length of the light pattern image 140 (FIG. 3 145), and the distances between the light sensors 121, 122 and 123 are arranged at the same distance, ), The central light sensor 122, and the right light sensor 124 are arranged at the same distance, but are arranged wider than the lateral length (Fig.

        The light ray pattern image 140 shown in FIG. 3 is irradiated with light of a rectangular shape having a length 145 longer than the width 144, and a diagonal portion 142 connecting the lower right corner from the upper left corner, The first light ray region 141 and the second light ray region 143 form a pattern of light rays separated from each other by the light rays.

        On the other hand, in another type of ray pattern image, the diagonal line is connected to the upper right side and the lower left side of the inside of the rectangle, or the ray pattern image in which the light is irradiated only at the diagonal portion and the diagonal portion, The same method can be applied to the calculation.

        Also, in the present invention, the light beam pattern image 140 will be described by taking a visible ray as an example, but it will be obvious that a laser beam, an infrared ray,

        The swing information calculator 150 receives an electrical signal such as a difference in sensing time interval and a difference in sensing holding time with respect to the light beam pattern image sent from the optical sensor and outputs swing information (swing speed, swing trajectory, Lie angle, sweet spot error distance) can be calculated.

        In addition, the swing information calculation unit 150 may be configured to allow the golfer to receive the type of the club selected by the radio signal, and to receive the unique characteristics (loft angle, sweet spot information per club, club type, etc.) The swing information received from the optical sensor can be summed and calculated.

        Hereinafter, a brief description of each element of the swing information (swing speed, swing trajectory, striking angle, club face angle, lie angle, and sweet spot error distance) and a method and an example of calculating using the light ray pattern image 140 do.

        1. Set the location for each club type

        Clubs have a number of unique characteristics depending on the type of shaft, lie angle, and loft angle.

        Gwangnyeong Golf Club is a club with a real shape, but in order to apply the unique swing information of each club, it is necessary to set the position of the golfer and golfer at the same distance as the actual club, It is possible to calculate and apply the swing information such as the lie angle and the swing trajectory.

        Using the size of the ray pattern image according to the distance from the ray golf club to the golf ball, the golfer sets his position and swings, and uses the measured value of the lie angle shown here as swing information.

        According to the embodiment, a club comparison plate (130 in FIG. 2) in which a size of a ray pattern image per club is displayed on a swing plate is set and a light pattern image is examined to set a position of a golfer .

        In FIG. 4, two clubs have been described, for example, in which the golfer sets the golfer's position differently for the club in order to use the club having a different shaft length.

        When the golfer irradiates and matches the light pattern image on the club comparative plate 130 disposed on the swing plate, the length D2 of the light pattern image of the club 100B corresponds to the length of the driver, It can be seen that the length D1 is confused with the 7 iron.

        2. Calculation of swing speed (head speed)

        The club's swing speed (head speed) is the factor that affects the distance of the hit golf ball.

In FIG. 7, light beam pattern images 140A and 140B are sequentially sensed on the optical sensor disposed on the right side 124 and the left side 120 with respect to the center of the swing plate as the light beam golf club passes over the swing plate. At this time, the head speed can be measured using the time interval (D) of the sensing point detected by each optical sensor (124, 120)

Can be calculated by the following equation (1).

[Equation 1]

Swing speed = distance between optical sensors / time interval between optical sensor detection (D)

       D: Time taken for the light beam pattern image to swing from the light sensor 124 to the light sensor 120

        3. Calculation of Swing Path Angle

        The swing orbit is shown in (A) of FIG. 13, which means a rotation curve of a path from the ball to the finish after the club head is moved away from the ball in the backswing, and is indicated by IN TO OUT, IN TO IN and OUT TO IN There are different types of swing trajectories and numerically represent the angle between the goal point and the straight line. It also affects the angle and direction of the ball along with the headface angle of the club during golf swing. Element.

        8D shows a light beam pattern image sequentially sensed by an optical sensor disposed at the right swing plate 124, the center 122, and the left 120 as the light beam golf club that performs the in-out swing passes the swing plate. Are detected while moving from the toe to the rear of the club head, such as 140A, 140B, and 140C, respectively. At this time, the length D1 of the first sensing holding time and the second sensing holding time length The swing trajectory can be obtained by measuring the change of the swing distance D2.

        In FIG. 8 (D), the angle 166 is an angle of the swing trajectory with respect to the swing trajectory of the club in contact with the line connecting the golf ball and the target point in a straight line, The angle of the swing trajectory 166 can be obtained by using the length of the straight line connecting and the movement interval 165 of the club head face detection point sensed by the optical sensors 124 and 120 during the swing.

        The movement interval 165 of the club head face detection point is a distance between the first sensing holding time length D1 and the second sensing holding time length D2 sensed by the optical sensor 124 before the striking and the optical sensor 120 after the striking There is a proportional relation with the amount of change and it can be calculated by the following equation (2).

&Quot; (2) "

The movement distance of club head face detection point (165) =

(Length of club head * D1 / (D1 + D2) ) - (length of club head * D1 / (D1 + D2) )

                       Detection value before hitting Detection value after hitting

☞ Length of Club Head: 145 of Figure 3

The first sensing retention time and the second sensing retention time: The first light ray region (FIG. 3 141) and the second light ray region

   (Fig. 3 (143)),

        The angle [theta] of the swing trajectory is calculated by using the movement interval 165 of the detection point calculated in [Equation 2]

 Can be calculated by the following equation (3).

&Quot; (3) "

TAN &thetas; = movement distance of the club head face detection point 165 / distance between the light sensor 124 and the light sensor 120

          ☞ θ: Angle of the swing orbit

       8A is a view for explaining a case in which the swing trajectory is in a state where a first sensing holding time length sensed by the optical sensor 120 after the striking via the optical sensor 122 at the striking by the optical sensor 124 before striking The length of the first sensing holding time and the length of the second sensing holding time that are sensed by the optical sensor after the striking, striking, and striking are not changed, Can be calculated as follows.

        [Detection time value before hitting = Detection time value after hitting = Detection time value after hitting]

This means that the same portion of the club head has been continuously sensed in the optical sensor 120 after the striking via the optical sensor 122 before the striking at the striking point.

         8B is a view for explaining a case in which the swing trajectory is in the out-of-focus state. In the case where the swing trajectory is in the out-of-focus state, the first sensing retention time length sensed by the optical sensor 120 after the striking, And the second sensing holding time length can be calculated by the above-described formula (2) as follows.

        [Detection point value before impact <Detection point value at impact <Detection point value after impact]

This means that the light sensor 122 is moved from the light sensor 124 before the batting to the light sensor 120 after the batting through the center of the club head in the heel direction sequentially from the toe of the club head But it is detected

have.

        8C is a view for explaining a case where the swing trajectory is out-to-out. In the case where the swing trajectory is out-of-sight, the first sensor holding time detected by the optical sensor 120 after the striking via the optical sensor 122 at the striking- The magnitude of the ratio of the length to the second sensing holding time length can be calculated by the above-described expression (2) as follows.

       [Detection time value before hitting> Detection time value when hitting> Detection time value after hitting]

This means that the light sensor 122 is moved from the light sensor 124 before the striking through the light sensor 122 at the striking point to the light sensor 120 after the striking sequentially from the heel of the club head through the center to the toe direction It can be seen that it was detected

        4. Calculation of attack angle

        The batting angle is classified into Up Blow and Down Blow according to the batting angle as shown in FIG. 13 (B) and added to the loft angle inherent to the club, so that the launch angle ) Is an angle between the swing plate (ground surface) and the swing orbit, and can be expressed numerically.

        In order to determine the angle of impact of a golf club during a swing, determine the distance from the optical sensor before striking and the distance from the optical sensor after striking relative to the golf club relative to the golf club. It is possible to calculate and calculate the batting angle using the following procedure.

        Step 1: Finding the distance between the golf club and the optical sensor

        6A, the light pattern image sensing and holding time of the light beam golf clubs 100C, 100B, and 100A during the swing detected by the light sensor 124 before the swing and the light sensor 120 after the swing is measured, A distance 201 to the optical sensor 120, and a distance 202 between the golf club and the optical sensor 124, respectively.

        5 is a diagram showing an example in which the light beam pattern image emitted by the light beam golf club 100 is detected by the light sensor 120 in order to calculate the distance between the swinging golf club 100 and the light sensor 120 Using the retention time and swing speed, the length 144 of the light pattern image sensed by the light sensor 120 can be known and the length 144 of the light pattern image can be used to determine the distance between the golf club 100 and the light sensor 120 The distance 201 can be found.

        5, the distance 201 between the golf club 100 and the optical sensor 144 can be calculated by the following equation (4).

&Quot; (4) &quot;

Distance between the club and the sensor = (length of the measured ray pattern image * 0.5) / TAN (? * 0.5)

   慮: Angle of irradiation of the beam pattern image emitted by the club (refer to 202 in FIG. 5)

        Step 2: The process of deriving the batting angle

        The distance 201 between the light ray golf clubs 100C, 100B, and 100A during swing and the light sensor 120 on the left side of the center of the swing plate in FIG. 6A, 124, the distance between the ball position and the golf club being swung can be determined by the middle line, since the ball is positioned at the center of the left and right optical sensors, It is possible to find the striking angle 200.

         FIG. 6B is a diagram for explaining a mathematical expression for calculating the batting angle using the middle line and the cosine second rule, and the theorem of the middle line is a theorem describing the relationship between the middle line and the three sides of the triangle, The distance of the ball and the club can be calculated by applying Equation (5).

C &lt; 2 &gt; + b &lt; 2 &gt; = 2 (L &lt; 2 &

           A / 2: distance between the left optical sensor 120 and the center optical sensor 122

           C: Distance between the golf club and the left optical sensor 120

           ☞ b: Distance between the golf club and the right optical sensor 124

           L: Distance between the golf club and the central light sensor 122

        The cosine second law calculates an angle using the length of three sides of the triangle, and the angle of attack can be calculated by applying Equation (6).

COS (θ + 90 °) = (L² + (a / 2) - c²) / 2 * L * (a / 2)

             ☞ θ: Striking angle

        9A shows the angle of the club in the upward blow and the length of the light ray pattern image sensed by the sensor. It is a detection of the light ray pattern image 140A sensed by the light sensor 124 before the strike, It can be seen that the sensing holding time D2 of the light beam pattern image 140B sensed by the optical sensor 120 after the striking is longer than the holding time D1.

         That is, the distance between the left optical sensor and the right optical sensor is longer than the distance between the left optical sensor and the right optical sensor based on the swinging golf club, and it can be seen that this is an upward blow, Can be obtained by the second law of the middle line and the cosine second rule by using the width of the light ray pattern image sensed by the left and right optical sensors as shown in Equation 4, Equation 5, and Equation 6.

         9B shows the length of the light beam pattern image sensed by the sensor when the club is struck perpendicularly to the swing plate. The detection and maintenance of the light beam pattern image 140A detected by the light sensor 124 before the striking It can be seen that the time D1 is the same as the detection holding time D2 of the light beam pattern image 140B sensed by the optical sensor 120 after the strike.

        That is, the distances from the left optical sensor and the right optical sensor are the same with respect to the golf club being swung, and when the above equations (4), (5), and (6) 0 is calculated.

         9C shows the angle of the club at the down blow and the length of the image of the light ray pattern sensed by the sensor. The detection of the light ray pattern image 140A sensed by the light sensor 124 before the strike It can be seen that the sensing holding time D2 of the light beam pattern image 140B sensed by the optical sensor 120 after the striking is shorter than the holding time D1.

        That is, the distance between the left optical sensor and the right optical sensor is shorter than the distance between the left optical sensor and the right optical sensor based on the swinging golf club, and it can be seen that this is a down blow, Can be obtained by the second law of the middle line and the cosine second rule by using the width of the light ray pattern image sensed by the left and right optical sensors as shown in Equation 4, Equation 5, and Equation 6.

        5. Calculation of the club face angle

        FIG. 13 (A) shows the angle of the club face, which is expressed by a numerical angle with respect to a straight line parallel to the swing plate connecting the ball and the target point. In the case of a square, It is divided into the case of being closed and whether or not the alignment of the club face is one of factors affecting the direction and deflection of the ball.

        The angle of the club face can be calculated by using the change of the light ray pattern image which appears during the swing of the golfer swinging to the ray golf club.

         FIGS. 10A, 10B and 10C are views showing a light pattern image when the light beam golf club passes the swing plate and a state (A) (Aim) state, and (C) shows a case of a closed state.

        The angle of the club face can be calculated by using the difference D between the sensing points of time when the light beam pattern images 140A, 140B and 140C are sensed between the upper light sensor 121 and the lower light sensor 122, (121) is detected first, the closed state lower light sensor (122) can be determined to be open if it is detected first

The angle can be calculated by the following equation (7).

TAN [theta] = D / the distance between the upper light sensor 121 and the lower light sensor 122

            ☞ θ: Angle of club face

           ☞ D: Difference in the time of detection of the upper and lower light sensor * Club speed

        It is obvious that the angle of the club face is measured differently depending on the angle of the lie, so that it is obvious that the calculated angle of the club face and the angle of the lie angle should be considered.

        6. Output of Lie Angle

        13 (C) shows the rake, in which the shaft of the golf club and the swing plate

(Ground), which means that the longer the shaft of the club is, the smaller the lie angle is, and each golf club has its own unique lyre.

        The Rayleigh golf club compares the changing lie angle of the swinging golfer's actual swing with the unique lie angle of each of the clubs selected by the golfer, so that accurate swing information can be calculated and applied.

        11A, 11B, and 11C illustrate examples of a club having an angle of 90 degrees, an intermediate-shaft-length club, and a long-shaft-length club, (D1, D2) are measured according to the following equation.

        That is, when the light pattern image 140C, 140B, 140A emitted from the light beam golf club during the swing is detected by the swing-plate upper light sensor 121 and the lower light sensor 123, D2) can be measured and the lie angle can be measured. The calculation method is the same as that for obtaining the above-mentioned batting angle.

        The distance between the golf club and the upper light sensor 121 and the distance between the golf club and the lower light sensor 123 are measured by measuring the sensing hold times D1 and D2 sensed by the upper light sensor 121 and the lower light sensor 123, The distance can be calculated and the distance between the golf club and the central optical sensor 122 (golf ball) can be calculated by the middle line theorem and the lie angle calculated using the cosine second rule.

        By substituting the values defined below in Fig. 6 (B), the lie angle can be calculated by the following equation (8).

COS (180 ° -θ) = (L² + (a / 2) - c²) / 2 * L * (a / 2)

            ☞ θ: Lie angle

The length 167, which is horizontally offset from the sweet spot of each of the ray pattern images 140A, 140B and 140C, Can be calculated by the following equation (9) by using the change depending on the holding time (D1) and the second sensing holding time (D2).

&Quot; (9) &quot;

Horizontal center error length (167) = (club head length / 2) - (club head length * (D1 / (D1 + D2))

           ☞ D1: 1st sensing hold time

           ☞ D2: 2nd detection hold time

           ☞ Length of club head: Figures 16 (A) and 16 (C) show 168

           ☞ Sweet Spot: Set the center of the club head (1/2 point)

&Quot; (10) &quot;

Horizontal center error rate [%] = 50 - (100 * D1 / (D1 + D2))

      ☞ D1: 1st sensing hold time

      ☞ D2: 2nd detection hold time
