Description

Golf Swing Analyzer

The present invention relates to a golf swing analyzer, and more particularly to a golf swing analyzer that is installed in a body or a club of a user who swings a golf swing, measures a swing locus, and displays a swing motion deviating from a swing locus determined as a reference plane by a pitch or length To a golf swing analyzer.

Golf is a game in which a golf club is rotated along the trajectory of a swing that matches the body of the golfer, and the ball is pitched in the direction and distance desired by the player. In golf, it is most important to realize the swing trajectory of a constant rotation surface that you have practiced each time. It is important to know whether the user is swinging as he or she has practiced in the past. Techniques for identifying the swing trajectory of the user are disclosed.

FIG. 1 is a diagram illustrating a configuration of a swing training system according to the related art, and FIG. 2 is a block diagram illustrating a swing trajectory calculating apparatus.

The prior art training system includes a swing locus calculating device 20, which is fixed to the golf club or the user's body. The swing locus calculating device 20 acquires the translational motion information and the rotational motion information of the club using a sensor module provided therein. Then, the obtained swing trajectory information is calculated by processing the exercise information of the club.

The console device 10 compares the pre-stored model swing locus information with the obtained swing locus information and outputs to the outside how much the swing similar to the exemplary swing locus has been performed.

The console device 10 informs the user whether the swing is consistent with the reference swing trajectory and the reference swing trajectory through the earphone 24 worn by the user or the bracelet 22 on the wrist.

The swing locator according to the present invention includes at least one acceleration sensor 200-a, 200-b, 200-c, at least one gyro sensor 300-a, 300-b, 300- A control unit 210, a communication unit 220, and a power supply unit 230.

The acceleration sensors 200-a, 200-b, and 200-c are three-axis acceleration sensors that sense dynamic forces such as acceleration, vibration, and impact. The gyro sensors 300-a, 300-b, and 300-c complement each other together with the acceleration sensors 200-a, 200-b, and 200-c to sense the swing trajectory, that is, the motion information of the club. The geomagnetic sensor 400 detects the direction of the magnetic field generated by the earth and detects the orientation like a compass. The movement direction of the club can be easily detected by using the geomagnetic sensor.

The control unit 210 calculates exercise information of the entire club based on measurement results from various sensors. The control unit 210 grasps the translational motion and rotational motion information of the club using the measurement results of the plurality of sensors. At this time, the controller 210 recognizes the swing information of the club including the horizontal (X), vertical (Y), depth (Z), pitch, yaw and roll information.

The trajectory information thus obtained is provided to the user, and the user can know only the fact that the swing trajectory itself does not match the pre-stored exemplary swing trajectory. That is, when the trajectory does not coincide with each other, sound or vibration is transmitted to the user, but the user can not specify which part of the swing is wrong.

According to an aspect of the present invention, there is provided a golf club system comprising a golf club, a golf club, and a golf club. The golf club includes: The golf swing analyzer according to the present invention is a golf swing analyzer.

The golf swing analyzer according to the present invention is a golf swing analyzer attached to a club head to measure a swing trajectory, which is a path on a space in which the club head moves, and to display a difference between the swing trajectory and a pre- A control unit (102) for generating a locus of the club head; A sensor 104 for grasping the position of the club head on the space and delivering it to the control unit 102; A scales conversion unit (106) for scoring the swing locus of the club head in a virtual place of business to generate a score; An acoustic output unit (108) for outputting the contents of the music score generated by the musical scale conversion unit (106) acoustically; And a memory 110 for storing information on the reference trajectory.

Hereinafter, a "golf swing analyzer" (hereinafter referred to as "analyzer") according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 3 is a view showing an installation position of a golf swing analyzer according to an embodiment of the present invention, FIG. 4 is an example of a swing trajectory of a club head represented by a three-dimensional line, FIG. As shown in FIG.

The analyzer (100) of the present invention is intended for use by a golfing user while wearing on his or her body. The user can maintain a constant swing trajectory by using the analyzer 100 when playing golf in a field or practicing in a practice field.

The analyzer 100 is mounted on the user's neck 1 or waist 2, the grip 3 of the club, the club head 4, etc., as shown in Fig.

The analyzer 100 measures the swing trajectory of the club head, wherein the swing trajectory refers to a path on the space in which the club head moves. When the golf swing is performed, it is preferable that the trajectory of the swing is formed to have a constant surface. The trajectory can be calculated by confirming the rotation surfaces of the neck, waist, grip, club head and the like. The most accurate and large swing trajectory can be grasped by mounting the analyzer 100 on the club head 4 in which the golf ball and hit are performed. In the present invention, it is assumed that the analyzer 100 is installed in the club head.

When the user rotates the club, the motion surface of the club head forms a locus close to the circle. The user tries to swing along the same trajectory every time, but the actual trajectory size and height may vary slightly. As shown in FIG. 4, when the trajectory of the swing moves up and down, it is possible to construct an imaginary laying ground having an upper boundary and a lower boundary as an outline. That is, when the flat sheet music sheet is rounded and laid along the locus of the club head, a substantially circular sash belt is formed. The trajectory of a user's repeated swing can vary from one to another, but it does not work well if there is a large difference between the upper and lower bounds. Therefore, the maximum and minimum boundaries can be determined to some extent through a number of practice swings.

When a three-dimensional sash belt which is generated in accordance with the rotation of the club head is spread on a plane, it is expressed as shown in Fig. The analyzer 100 continuously grasps the position of the club head while the swing of the user is performed, and combines the detected position information to grasp the overall swing trajectory. In the present invention, it is considered that the position of the club head where the analyzer 100 is installed can be grasped by grasping the position of the analyzer 100.

The internal structure of this analyzer 100 is shown in FIG. 6, which is a block diagram illustrating the internal components of the swing analyzer of the present invention.

The analyzer 100 comprises a control unit 102, a sensor 104, and other output means or input means.

The control unit 102 is formed in the form of a microprocessor and is responsible for all the signals generated by the analyzer 100 and for controlling the components.

The sensor 104 may comprise a velocity sensor 104a, an acceleration sensor 104b, and a gravity sensor 104c as means for grasping the current position, velocity, acceleration, direction, etc. of the analyzer 100. [

The speed sensor 104a is a sensing means for confirming how fast the analyzer 100 is moving at a current speed and the acceleration sensor 104b measures a moving acceleration of the analyzer 100. [ The gravity sensor 104c senses the gravitational acceleration and measures the direction or orientation of the analyzer 100. [ The components included in the sensor 104 of the present invention are merely examples and may be changed by other means as long as the apparatus can identify the position, movement path, height, and direction of the analyzer 100.

The control unit 102 generates a swing trajectory in which the club head moves based on the measurement value transmitted from the sensor 104. [

The scale conversion unit 106 plays a role of creating a score by recording the swing trajectory of the club head on a virtual score sheet as a note. To do this, a virtual laying line is first constructed based on the information on the reference trajectory previously input by the user, and the position and height of the club head relative to the inside of the line are analyzed to form a note. For reference, the reference trajectory defined in the present invention refers to a trajectory stored in advance by a user, and means a swing trajectory selected by the user as a swing trajectory most suitable for the user's body. The user finds an optimized swing trajectory through a plurality of practice swings, and stores the swing trajectory thus found in the analyzer 100 as a reference trajectory. The scale conversion unit 106 analyzes the difference between the stored reference trajectory and the actual trajectory, and notifies the user of the difference. And the imaginary laying line is configured to be perpendicular to the striking surface of the club head.

The sound output unit 108 is a means for acoustically outputting how much the trajectory of the actual swing is deviated from the reference trajectory when the user actually swings in a state in which the reference trajectory is set. To this end, the musical score content (melody, beat) generated by the musical scale conversion unit 106 is output as sound. The sound output unit 108 outputs such that the difference between the scales increases as the degree of departure increases, and decreases as the degree decreases.

The memory 110 includes positional information on the reference trajectory together with various information set by the user.

The input button 112 is used by the user to use the analyzer 100 or to store information about the reference trajectory. In order to perform a putting or a chip shot, the width of the front and rear swing of the club head may be predetermined. At this time, the input button 112 is also used to store information about the swing width (movement distance of the club head).

FIG. 7 is a conceptual view showing the position of the club according to the order of the golf swing. FIG. 8 is an example in which the swing direction is expressed by a causal out, and FIG. 9 is an example in which the direction of the swing is represented by a musical note.

As shown in Fig. 7, when looking at the movement of the club head in front of the swinging user, it can be seen that a large circle is drawn. In some cases, it may be an ellipse or a circle moving slightly to the left or right, but for convenience of explanation, it is assumed that the club head moves in a circular shape.

The movement of the club head in front of the right-handed user is preceded by a backswing movement that goes from the 6 o'clock position (address posture) clockwise through 9 o'clock to 12 o'clock (or beyond). Then, at the top, the downswing is turned counterclockwise, and when the club head passes the 6 o'clock point, the golf ball is hit. The club head that hits the golf ball is followed by the 9 o'clock point, and the swing stops at the final finish position.

In FIG. 8, the trajectory indicated by (2) is a straight swing, (3) is an in-out swing, (1) is an out-in swing . For example, if the locus of the club head due to the (1) burn-out-in swing is represented on the flat line in FIG. 5, it is expressed as shown in FIG. In other words, the position of the club head (the path descending from the right far position to the left near the position) can be drawn on the score sheet of the leader spread on the front bottom of the user. This is the swing trajectory scale on which the acoustic output of the present invention is based.

The position of the club head drawn on the line is recorded at regular time intervals. If the linear velocity of the club head is constant, the intervals of the notes drawn on the line are all equal. However, if the linear velocity of the club head is not constant, different lengths of notes are gathered together to create a melody, which allows the user to learn the rhythm of his swing speed.

FIG. 10 is an exemplary view showing the position of a club rotating at a constant speed on a line, and FIG. 11 is an exemplary view showing a position of a club rotating at a non-constant speed on a line.

As shown in FIG. 10, when the velocity of the club head is constant, all of the notes are represented by the same length. However, when the velocity is not constant as shown in FIG. 11, the length of the note varies. That is, notes in a fast section have a short length, and notes in a slow section have a long length. For example, in FIG. 11, if the interval (⑤-④-③-②-①) in the first half is composed of quarter notes, the interval (①②③④⑤⑥⑦⑧⑨) in the latter half is composed of eighth notes or similar notes shorter than quarter notes. Through the length of the note, the user can easily know which part of his swing is fast and which part is slow.

FIG. 12 is a conceptual diagram showing the difference between the reference trajectory and the actual trajectory, and FIG. 13 is a diagram exemplifying a situation in which the swing direction is changed to causal out.

As described above, the memory 110 stores information on the reference trajectory that the user recognizes and stores as being most optimized. The analyzer 100 analyzes the difference between the reference trajectory and the actual trajectory. have. In Fig. 12, the difference between these two trajectories is shown visually.

In general, the reference trajectory is a standardized trajectory that does not deviate downward from its swing. Therefore, if the swing moving along the reference trajectory is described as a note, it is disposed along the middle line ("Shi" in the case of the scale) of the line of sight (see FIG. 10). However, when the swing trajectory is shaken up and down because the actual swing is not constant As in 13, there will be cases where the scales deviate from the poem.

For reference, the numbers shown on the line in FIG. 13 are based on the position numbers of the club heads shown in FIG. That is, ① is defined as 9 o'clock at the end of the backswing, ⑤ is at 6 o'clock of the impact moment, and ⑨ is defined as 3 o'clock at the end of the follow swing.

13, in the first backswing section (⑤-④-③-②-①), the club head tends to descend downward. That is, it can be seen that the actual trajectory of the club head falls downward relative to the reference trajectory.

On the other hand, the club head tends to go up in the section where the swing is started and hit and follow (①-②-③-④-⑤-⑥-⑦-⑧-⑨). In other words, it can be seen that the actual trajectory rises toward the reference trajectory and rises further above the reference trajectory.

As a rough representation, in the backswing phase, it becomes the scale of "Si-la-soul-pa-mi." In this swing stage, the scale of "Mi-pa-sole-la-si-do- . ≪ / RTI > Based on the information about the swing trajectory transmitted from the control unit 102, the scale conversion unit 106 expresses the position of the club head with such a note.

The score indicated is output by the sound output unit 108 to the sound having the shortest length and the actual melody. The user can actually hear these sounds in real time while swinging. That is, the analyzer 100 rotates together with the club head, and the change due to the rotation is directly recorded as a note and outputted as sound, so that the user can hear the sound due to his / her swing each time he swings. If you swing in accordance with the reference trajectory, you can hear only the notes of "Scale" continuously, but when you swing that does not match the reference trajectory, you hear other scales. And when the trajectory of the swing is not flat and it is shaken up and down, you hear the sound with the change of scale, so you can clearly grasp the state of your swing.

The length of the note is optimized for your body. If the length of the note differs from the stored information, you can see that the speed of the club head has changed.

Information on the reference trajectory is stored in advance by the user. By operating the input button 112, information on the reference trajectory can be easily changed or updated. In some cases, the sensor 104 measures the trajectory information by performing a plurality of repeated swings, and the controller 102 may calculate and store the average value of the measured plurality of swing trajectory information as the reference trajectory.

On the other hand, FIG. 14 is an example of a boundary line set on the right and left sides in the putting operation on the line.

The analyzer 100 of the present invention may provide guidance to limit the swing width as well as the swing trajectory. In the case of putting or short-distance chip shots, you can control the distance by setting the amplitude of the club head. You can send the golf ball to the correct distance by pre-setting the left and right boundaries of the section where the club head reciprocates .

Before entering a putting or a chip shot, the input button 112 is pressed to switch to the borderline setting mode. In this state, the user moves the club head from side to side to determine the amplitude corresponding to the distance he or she is going to send. Then, when the club head reaches the boundary line by the backswing to the right, the input button 112 is pressed to designate the first boundary line on the right side. When the club head reaches the boundary by swinging to the left, the second boundary line on the left side is designated by pressing the input button 112 again. In this state, when the user performs a putting or a chip shot, the analyzer 100 detects if the club head exceeds two boundaries. If the backswing or follow is longer than initially determined, the club head will cross the first or second boundary. At this time, the sound output unit 108 sounds a warning sound to notify the user that the movement of the club head is excessive. When you swing, you are always careful not to sound, so you can always swing to the correct amplitude.

In some cases, the amplitude of the club head may be set to an angle without setting two boundary lines on the left and right sides. That is, if you set the club head amplitude to 10 degrees for a 5-meter putting, you will be alerted when a motion exceeds 10 degrees. Even when the amplitude at the time of 20-meter chip shots is 30 degrees, it is possible to monitor in real time whether an optimized swing is being performed by setting an angle in advance.

On the other hand, Fig. 15 shows an example in which the trajectory is expressed in multiple stages in a state in which the radius of the trajectory of the swing changes.

In the above example, it is assumed that the trajectory of the swing becomes one circular band, and a method of ringing the alarm when the club head moves up and down within one band has been described. However, there are cases where the radius of rotation of the circular band, which is the trajectory of the swing, may change. This means that the swinging circle is getting larger or smaller as the movement of the hand or arm holding the club changes.

Generally, in one swing, a trajectory increases in a certain portion, and a trajectory becomes smaller in a certain portion. In the case of amateur golfers, it is not always possible to constantly swing. In backswing, the trajectory becomes smaller, and in the downswing and follow, the trajectory may become larger.

Even if the swing locus's turning radius is small or large, it is not possible to correct the inaccurate swing by outputting sound considering only the club head height in the actual locus. When the swing radius is large, it is possible to set the tone to be one octave higher than that of the musical scale when moving along the reference trajectory, and to make one octave lower when the swing becomes smaller. The user can easily recognize that the swing trajectory of his or her own swing becomes smaller or smaller by confirming that the sound is remarkably higher or lower than the reference trajectory. The adjustment of the octave is performed under the control of the scale converter 106 in the process of generating the score.

In some cases, the octave of the swing trajectory may not be changed, but the user may be notified by changing the type of sound (musical instrument, electronic sound, frequency, etc.). The type of sound is changed by the sound output unit 108.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, As will be understood by those skilled in the art. Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
