[0027] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. It should be understood that the drawings include exaggerated representations and representations different from the dimensional ratios of the actual structures in order to facilitate understanding of the present invention. In addition, when there are multiple embodiments, the same or common elements are designated by the same reference numerals throughout the specification, and duplicated explanations are omitted.

[0028] FIG. 1 is a diagram showing the overall configuration of a golfer's posture calculation device 100 including a golfer's measurement device 1 of this embodiment.

[0029] [Overall configuration] The posture calculation device 100 of this embodiment is for measuring the posture of a golfer during play (for example, posture at the time of shot or address). In a preferred embodiment, the measured data is stored in a predetermined location and can be referred to by related parties including golfers when necessary. This allows, for example, a golfer to compare and analyze the posture during play with the result of the shot, and to use the data to improve his / her skills.

[0030] The posture calculation device 100 of this embodiment includes, for example, a golfer measurement device 1, a mobile terminal 30, and a golf club 40. Each component will be described in detail below.

[0031] [Golfer measurement device] The golfer measurement device 1 includes a pair of first sensor devices 10 for measuring the posture of golf shoes S including a pair of left and right first shoes SL and second shoes SR worn by the golfer, and a second sensor device 20 that can be attached to the golfer at a position higher than the golf shoes S worn by the golfer.

[0032] The first sensor device 10 includes a left first sensor device 10L that measures the posture of a first shoe SL worn on the golfer's left foot, and a right first sensor device 10R that measures the posture of a second shoe SR worn on the golfer's right foot.

[0033] In a preferred embodiment, the measuring device 1 further includes a first shoe SL and a second shoe SR, and the first sensor device 10 is attached to the first shoe SL and the second shoe SR in advance. Specifically, the left first sensor device 10L is attached to the first shoe SL, and the right first sensor device 10R is attached to the second shoe SR, respectively.

[0034] The first sensor device 10 may be built into, for example, a component (e.g., a sole, an inner layer, etc.) of the golf shoes S. In another embodiment, the first sensor device 10 may be removably attached to the golf shoes S using various attachment members (clips, belts, fasteners, etc., not shown).

[0035] Fig. 2 shows a perspective view of a first shoe SL, which represents a pair of golf shoes S, placed on a horizontal ground G. Fig. 3 is a front view of Fig. 2. As shown in Figs. 2 and 3, the first shoe SL defines an axis y in the shoe longitudinal direction. This axis y extends from the heel to the toe of the shoe. The axis y passes through the left first sensor device 10L of the first shoe SL and is parallel to the ground G.

[0036] The first shoe SL also defines an axis x that is perpendicular to the axis y and horizontal to the ground G, and an axis z that is perpendicular to the axes y and x. The axes x, y, and z intersect in the left first sensor device 10L and the right first sensor device 10R, respectively. The intersections are used as representative points that represent the positions of the first shoe SL and the second shoe SR.

[0037] Fig. 4 is a block diagram showing an example of an electrical configuration of the first sensor device 10. As shown in Fig. 4, the left first sensor device 10L includes, for example, an inclination sensor 11L and a battery 12L. Similarly, the right first sensor device 10R includes, for example, an inclination sensor 11R and a battery 12R. The inclination sensors 11L and 11R operate by receiving power from the batteries 12L and 12R, respectively.

[0038] The inclination sensors 11L and 11R can measure the postures of the first shoe SL and the second shoe SR, respectively. In this embodiment, the inclination sensors 11L and 11R measure the postures of the first shoe SL and the second shoe SR, respectively, by measuring the inclination angle θ L and θ R (See Figure 5) can be measured.

[0039] For example, when a golfer addresses the ball on a sloping surface (lie) with his / her left foot up, the first shoe SL and the second shoe SR generally tilt counterclockwise with respect to the axis y of the shoe longitudinal direction when viewed from the front. This tilt is measured by the tilt sensors 11L and 11R, for example, as a positive value (see +θ in FIG. 3). Conversely, when a golfer addresses the ball on a sloping surface (lie) with his / her left foot down, the first shoe SL and the second shoe SR generally tilt clockwise with respect to the axis y of the shoe longitudinal direction when viewed from the front. This tilt is measured by the tilt sensors 11L and 11R, for example, as a negative value (see -θ in FIG. 3).

[0040] As the tilt sensors 11L and 11R, for example, an acceleration sensor or a geomagnetic sensor is suitably used.

[0041] In addition, the left first sensor device 10L of this embodiment may further include a control unit 13L and a memory unit 14L. Similarly, the right first sensor device 10R of this embodiment may further include a control unit 13R and a memory unit 14R.

[0042] The control units 13L and 13R are configured with, for example, a CPU, a ROM, a RAM, etc. The control units 13L and 13R operate by receiving power supply from the batteries 12L and 12R, respectively.

[0043] The memories 14L and 14R are each composed of a storage device such as a rewritable flash memory. The memories 14L and 14R store and erase data by receiving power from the batteries 12L and 12R. The memories 14L and 14R store programs 14La and 14Ra, respectively. The CPUs of the control units 13L and 13R read out the programs 14La and 14Ra and perform predetermined processing. In this embodiment, the control units 13L and 13R, for example, calculate the tilt angle θ measured by the tilt sensors 11L and 11R at a predetermined sampling period. L and θ R The data in the storage units 14L and 14R are stored in chronological order in the storage units 14L and 14R.

[0044] [Second sensor device] As shown in FIG. 1, the second sensor device 20 is housed in, for example, a housing. In a preferred embodiment, the second sensor device 20 is provided in a wearing device W that can be attached to a golfer. The wearing device W in this embodiment is configured as a belt member that can be attached to, for example, the waist or abdomen of a golfer. The wearing device W can be attached directly to the golfer's body or indirectly via clothing, a hat, or the like. Instead of a belt member, the wearing device W may be configured as various attachment members such as a badge, a clip, a hook-and-loop fastener, or the like. The second sensor device 20 may also be a so-called wearable device.

[0045] 5 shows a front view of a golfer 200 wearing the second sensor device 20 at address. As shown in FIG. 5, the second sensor device 20 of this embodiment is worn on the abdomen or waist of the golfer 200. The second sensor device 20 is located at approximately the center of the golfer's abdomen in the left-right direction. The second sensor device 20 is located at a distance L from the second sensor device 20 to the first shoe SL and the second shoe SR. R and L L In addition, in FIG. 5, the symbol HL indicates the horizontal axis.

[0046] Fig. 6 is a block diagram showing an example of an electrical configuration of the second sensor device 20. As shown in Fig. 6, the second sensor device 20 includes, for example, two distance sensors 21L and 21R and a battery 22. The distance sensors 21L and 21R operate by receiving power supply from the battery 22. For example, an ultrasonic sensor or a radar sensor is suitable for the distance sensors 21L and 21R. A case where the distance sensors 21L and 21R are ultrasonic sensors will be described below.

[0047] The distance sensor 21L is positioned so as to face the first shoe SL when the second sensor device 20 is attached to the golfer 200. The distance sensor 21L can transmit ultrasonic waves toward the first shoe SL and can receive ultrasonic waves reflected by the first shoe SL. The distance sensor 21L can measure the distance L to the first shoe SL by measuring the time from transmitting the ultrasonic waves to receiving the reflected waves. L On the other hand, the distance sensor 21R is positioned to face the second shoe SR when the second sensor device 20 is attached to the golfer 200, and, like the distance sensor 21L, can measure the distance L to the second shoe SR. R can be measured.

[0048] The second sensor device 20 may further include, for example, a control unit 23 and a storage unit 24.

[0049] The control unit 23 is composed of, for example, a CPU, a ROM, a RAM, etc. The control unit 23 receives power supply from the battery 22 and operates.

[0050] The memory unit 24 is composed of a storage device such as a rewritable flash memory. The memory unit 24 receives power from the battery 22 to store and erase data. A program 24a is stored in each memory unit 24. The CPU of the control unit 23 reads out the program 24a and performs a predetermined process. In this embodiment, the control unit 23 stores the distances L measured by the distance sensors 21L and 21R at a predetermined sampling period. L , L R The data is stored in the memory unit 24 in chronological order.

[0051] [Operation of this embodiment] According to the measuring device 1 of the present embodiment configured as described above, the first sensor device 10 detects an inclination angle θ about the axis y of the first shoe SL in the shoe longitudinal direction with respect to the horizontal axis HL. L , and the inclination angle θ of the second shoe SR about the axis y in the shoe longitudinal direction. R These postures of the golf shoes S are useful for grasping the state of the lie on which the golfer is standing, particularly the slope of the lie, such as the left foot up or down.

[0052] In addition, in the measurement device 1 of this embodiment, the second sensor device 20 measures the distance L from a position higher than the golf shoes S worn by the golfer 200 to the first shoe SL and the second shoe SR. L and distance L R This distance L L and L R helps identify how the golfer's 200 upper body is oriented relative to the lie.

[0053] Figures 7(A) and (B) show two typical states in which a golfer 200 addresses the ball on a slope (lie) with the left foot up. In Figure 7(A), the upper body of the golfer 200 is oriented nearly perpendicular to the slope, i.e., leaning to the left from the vertical direction (hereinafter referred to as "first state"). On the other hand, in Figure 7(B), the upper body of the golfer 200 faces vertically regardless of the slope of the ground (hereinafter referred to as "second state").

[0054] Here, when comparing the first state with the second state, the inclination angle θ L and θ R Therefore, the postures of the first shoe SL and the second shoe SR of the golfer 200 (the inclination angle θ L and θ R ) alone makes it difficult to distinguish between these two states.

[0055] On the other hand, the measuring device 1 of this embodiment has a distance L from the second sensor device 20 to the first shoe SL and the second shoe SR. L and L R Since it is possible to measure the distance L in the second state of FIG. L and distance L R The difference between the distance L in the first state of FIG. L and distance L R Therefore, by examining the difference in distance (LL-LR), it is possible to identify whether the golfer tends to be in the first state or the second state.

[0056] As described above, the measurement device 1 of the present embodiment can acquire information that enables a golfer's posture to be identified in more detail, which has been difficult to do in the past.

[0057] 6, the second sensor device 20 may further include a tilt sensor 25. The tilt sensor 25 operates by receiving power from the battery 22. As the tilt sensor 25, for example, an acceleration sensor or a geomagnetic sensor is preferable.

[0058] 5, the inclination sensor 25 detects an inclination angle θ of a hip line 201 of the golfer 200 relative to a horizontal axis HL when viewed from the front of the golfer 200. W The waist line 201 means a horizontal axis passing through the waist of the golfer 200 when viewed from the front while the golfer 200 is standing upright. The inclination angle θ of the waist line 201 of the golfer 200 W serves as information for identifying the posture of the golfer 200 in more detail.

[0059] [Golfer posture calculation device] Next, an embodiment of the golfer's posture calculation device 100 will be described. As shown in Fig. 1, the posture calculation device 100 of this embodiment includes a measurement device 1 and a mobile terminal 30. The mobile terminal 30 can calculate the posture of the golfer 200 in more detail based on the data measured by the measurement device 1.

[0060] Fig. 8 is a block diagram showing an example of an electrical configuration of the mobile terminal 30. As shown in Fig. 8, the mobile terminal 30 of this embodiment includes, for example, a communication unit 31, a control unit 32, a storage unit 33, a display unit 34, an input unit 35, and a battery 36 for supplying power to these units. For example, a laptop-type personal computer, a tablet, a smartphone, or the like may be used as the mobile terminal 30.

[0061] The communication unit 31 receives the tilt angle θ measured by the first sensor device 10. L and θ R and the distance L measured by the second sensor device 20. L , L R and θ WThe communication units 31 are connected to the first sensor device 10 and the second sensor device 20. The communication units 31 are connected to the first sensor device 10 and the second sensor device 20. The communication units 31, 16L, 16R, and 27 are connected to the second sensor device 20 and the first sensor device 10. The communication units 31, 16L, 16R, and 27 are connected to the second sensor device 20 and the second sensor device 20. The communication units 31, 16L, 16R, and 27 are connected to ...

[0062] The display unit 34 is composed of, for example, a liquid crystal display, and can display necessary information such as the calculated posture of the golfer. The input unit 35 is composed of, for example, a touch panel, operation buttons, a mouse, a keyboard, etc. The golfer 200 can operate the input unit 35 to perform a predetermined operation on the mobile terminal 30.

[0063] The control unit 32 calculates the relative positions of the first shoe SL and the second shoe SR based on the attitude information, the distance information, and the like received via the communication unit 31.

[0064] The storage unit 33 is composed of a storage device such as a rewritable flash memory. A program 33a is stored in the storage unit 33. The program 33a records the processing procedure of the control unit 32 and a calculation procedure for calculating the above-mentioned relative position.

[0065] In this embodiment, the relative position is calculated using the posture of the golf shoe S measured by the measuring device 1, the distance from the second sensor device 20 to the golf shoe S, and a function. For this function, for example, a multiple regression equation is used in which the relative position is used as a response variable and the posture and the distance are used as explanatory variables.

[0066] In addition, the relative position of the first shoe SL and the second shoe SR desirably includes, for example, as shown in FIG. 5, the height difference H between the first shoe SL and the second shoe SR, the horizontal distance R between the first shoe SL and the second shoe SR (sometimes referred to as the stance width), and / or the inclination angle θ of the stance of the golfer 200 relative to the horizontal axis.

[0067] [Multiple regression equation for elevation difference H] In this embodiment, the height difference H between the first shoe SL and the second shoe SR is obtained as the vertical distance between the representative point of the left first sensor device 10L and the representative point of the right first sensor device 10R. This height difference H can be obtained, for example, by the following multiple regression equation (1). H = α0 + α1 LL + α2 LR + α3 θ W +α4·θ L +α5·θ R …(1) Here, α0 is a constant term, and α1 to α5 are partial regression coefficients. This multiple regression equation (1) is obtained in advance by multiple regression analysis, and is stored in the storage unit 33.

[0068] [Multiple regression equation for stance width R] In this embodiment, the horizontal distance (stance width) R between the first shoe SL and the second shoe SR is obtained as the horizontal distance between the representative point of the left first sensor device 10L and the representative point of the right first sensor device 10R. This horizontal distance R can be calculated, for example, by the following multiple regression equation (2). R = β0 + β1 · LL + β2 · LR + β3 · θ W +β4·θ L +β5·θ R …(2) Here, β0 is a constant term, and β1 to β5 are partial regression coefficients. This multiple regression equation (2) is obtained in advance by multiple regression analysis, and is stored in the storage unit 33.

[0069] [Stance inclination angle θ] In this embodiment, the stance inclination angle θ is obtained as the angle of a straight line connecting a representative point of the left-side first sensor device 10L and a representative point of the right-side first sensor device 10R with respect to a horizontal axis. This inclination angle θ is calculated by the following formula (3) using the height difference H and stance width R. This formula is stored in the storage unit 33 in advance. θ=tan -1 (H / R) …(3)

[0070] [Timing of golfer's posture calculation] Next, a description will be given of the timing at which the posture of the golfer 200 is calculated. The posture calculation device 100 of this embodiment is programmed to calculate, for example, the posture of the golfer 200 at the time of a shot (at the time of impact). This measurement timing is specified by the golf club 40.

[0071] 1, a golf club 40 includes, for example, a shaft 41, a golf club head 42 provided at one end of the shaft 41, a grip 43 provided at the other end of the shaft 41, and a third sensor device 44. In this embodiment, the third sensor device 44 is attached to, for example, an end of the grip 43.

[0072] Fig. 9 is a block diagram showing an example of an electrical configuration of the third sensor device 44. As shown in Fig. 9, the third sensor device 44 includes, for example, an impact sensor 45, a control unit 46, a storage unit 47, a communication unit 48, and a battery 49 for supplying power thereto.

[0073] The impact sensor 45 detects the large force, acceleration, etc., generated when the golf club head 42 hits the ball, and thereby can identify that a hit has been made with the golf club 40. For example, an acceleration sensor or an angular velocity sensor is suitable for such an impact sensor 45.

[0074] The control unit 46 is composed of, for example, a CPU, a ROM, and a RAM. The storage unit 47 is composed of a storage device such as a rewritable flash memory. A program 47a is stored in the storage unit 47. The CPU of the control unit 46 reads out the program 47a and performs a predetermined process. The communication unit 48 is configured to be able to communicate with the communication unit 31 of the mobile terminal 30.

[0075] When the impact sensor 45 detects a shot of the golf club 40, the control unit 46 transmits a signal indicating that the shot has been made to the mobile terminal 30 via the communication unit 48.

[0076] The control unit 32 of the mobile terminal 30 that has received the signal communicates with the communication units 16L and 16R of the first sensor device 10 via the communication unit 31, and determines the inclination angle θ of the first shoe SL and the second shoe SR. L and θ R In addition, the control unit 32 of the mobile terminal 30 communicates with the communication unit 27 of the second sensor device 20 via the communication unit 31, and acquires the distances L from the second sensor device 20 to the first shoe SL and the second shoe SR. L and L R The control unit 32 of the mobile terminal 30 can then calculate the posture of the golfer 200 based on the acquired data.

[0077] The portable terminal 30 can display information related to the calculated posture of the golfer 200 in the form of characters or images on the display unit 34. The portable terminal 30 can also store the calculated posture of the golfer 200 in the memory unit 33, and can also transmit the calculated posture to an external server 50 (FIG. 1) or the like for storage.

[0078] It should be noted that the posture of the golfer 200 can be calculated not only at the time of the shot but also at the time of the address. For example, when a shot is detected by the impact sensor 45, the tilt angle θ at a time several seconds before the time of the shot (i.e., the time can be considered as the address state) is calculated. L and θ R and distance L L and L R By acquiring the above, it is possible to calculate the posture in the address state of the golfer 200. Such an embodiment is useful for evaluating the posture of the golfer 200 before and after a shot.

[0079] [Variations] 10 is a perspective view showing a modified example of the second sensor device 20. In the previous embodiment, the second sensor device 20 is configured as a single device. In this example, the second sensor device 20 is configured as a pair including a left second sensor device 20L and a right second sensor device 20R which are attached to the left and right halves of the golfer's body, respectively.

[0080] In the example of Fig. 10, the second sensor device 20 is provided on a wearing tool W that can be attached to a golfer. The wearing tool W of this embodiment is configured as a belt member that can be attached to the golfer's abdomen or waist, for example. The wearing tool W can be attached directly to the golfer's body or indirectly via clothing, a hat, or the like. Instead of a belt member, the wearing tool W may be configured as various attachment members such as a badge, a clip, a hook-and-loop fastener, or the like.

[0081] Fig. 11 shows a front view of a golfer 200 wearing the first sensor device 10 and the second sensor device 20 of Fig. 10 at address. As shown in Fig. 11, the second sensor device 20 of this embodiment is worn on the abdomen or waist of the golfer 200. Of the second sensor devices 20, the left second sensor device 20L is worn so as to be located on the left waist of the golfer 200, and the right second sensor device 20R is worn so as to be located on the right waist of the golfer 200. The left second sensor device 20L and the right second sensor device 20R each have the same configuration as the block diagram of the electrical configuration shown in Fig. 6.

[0082] The distance sensors 21L and 21R of the left second sensor device 20L measure the distance L from the left second sensor device 20L to the first shoe SL and the second shoe SR. LR and L LL The inclination sensor 25 of the left second sensor device 20L measures the inclination angle θ WL can be measured.

[0083] The distance sensors 21L and 21R of the right second sensor device 20R detect the distance L from the right second sensor device 20R to the first shoe SL and the second shoe SR.
