Thus, the counting data of the number of strokes according to a predetermined format is generated and output to the count processing unit 20.

  Further, the data related to the swing state and the data related to the impact output from the swing detection unit 12 and the impact detection unit 14 are stored in the swing basic information 350 of the storage unit 30 with time information input from the GPS unit 50. The

  It is ideal that the acceleration sensor and the angular velocity sensor of the inertial measurement unit 110 are each mounted so that the three axes coincide with the three axes of the sensor coordinate system (b frame) based on the inertial measurement unit 110. Causes an error in the mounting angle. Therefore, the hit count value detection unit 16 uses the correction parameters calculated in advance according to the mounting angle error to send the data relating to the swing state and the data relating to the impact (acceleration data and angular velocity data) to the sensor coordinate system (b frame). To convert the data to. Note that the count processing unit 20 described later may perform the conversion process instead of the hit count value detection unit 16.

Vector), and GPS data with time information and positioning accuracy information added thereto is output to the count processing unit 20. In addition, since the method of calculating a position and speed and the method of generating time information using GPS are publicly known, detailed description is omitted.

  The geomagnetic sensor 60 detects each geomagnetism in three axial directions intersecting each other (ideally orthogonal), and counts a digital signal (geomagnetic data) corresponding to the detected magnitude and direction of the triaxial geomagnetism. 20 is output. However, the geomagnetic sensor 60 may output an analog signal. In this case, the count processing unit 20 may A / D convert the output signal of the geomagnetic sensor 60 to generate geomagnetic data. .

  The storage unit 30 includes various IC memories such as a ROM (Read Only Memory), a flash ROM, and a RAM (Random Access Memory), a recording medium such as a hard disk and a memory card, and the like.

  The swing reference data 370 and the impact reference data 380 are obtained from the output from the inertial sensor of the inertial measurement unit 110 by the swing detection unit 12 and the impact detection unit 14 when the hit count unit 10 performs the hit count processing. When detecting an impact, reference data such as a threshold value serving as a criterion for detecting whether or not the movement of the golf club 90 is a swing and whether or not there is an impact during the swing of the golf club 90. .

The hole data 390 is map data of the holes that the player rounds. By placing the positioning data acquired by the GPS unit 50 on the hole data 390, the player's position in the hall can be grasped, You can catch the rough movement of the.

  The geomagnetic data table 330 is a data table that stores the geomagnetic data (the detection result of the geomagnetic sensor) received from the geomagnetic sensor 60 by the count processing unit 20 in time series.

  The calculated data table 340 is a data table that stores the speed, position, and attitude angle calculated by the count processing unit 20 using the sensing data in time series.

  The swing basic information 350 includes time-series information in which time information input from the GPS unit 50 is added to data related to the player's swing state and impact data output from the swing detection unit 12 and the impact detection unit 14. Is remembered.

  From the information stored in the swing basic information 350 in time series, it is possible to recognize the characteristics of the player's swing and actions before and after the swing action (routing action and the like). Therefore, in counting the number of strokes by the counting system 1 referring to the swing basic information 350, the number of strokes calculated by recognizing the individual difference (癖) for each player is corrected to eliminate the count value error due to the individual difference. be able to.

  The count processing unit 20 is configured by, for example, a CPU (Central Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), and the like, and stores based on the hit count value acquired from the hit count counter 10. According to various programs stored in the unit 30, a process for generating an accurate number of hits of the player is performed. Specifically, the count processing unit 20 receives the striking count value counted by the striking count counting unit 10 based on the output from the inertial sensor of the inertial measurement unit 110 by the striking count count acquisition unit 21, and the GPS unit 50 and the geomagnetism. The GPS data and the geomagnetic data are received from the sensor 60, respectively, and an accurate hit number of the player is generated by the hit number generating unit 250 using these data. The count processing unit 20 includes a batting number adjusting unit 255 that adjusts the batting number generated by the batting number generating unit 250 as necessary. Then, the count processing unit 20 transmits the generated player hit number to the display device 3 via the communication unit 40, and the display device 3 outputs the received hit number information in the form of text, image, sound, vibration, or the like. .

  The communication unit 40 performs data communication with the communication unit 140 of the display device 3. The communication unit 40 receives the batting number information generated by the count processing unit 20 and transmits it to the display device 3. The received command (such as the count start / stop command for batting number and the start / end command for batting number adjustment processing) is received and sent to the count processing unit 20.

[2. Counting (counting) method (processing procedure)]
Next, a player's batting number counting method (hitting number calculating method) will be described with reference to the drawings. In the present embodiment, a counting method (batting number calculation method) for counting the number of hits in a round in which a player plays 18 holes, for example, will be described. FIG. 3 is a flowchart showing an example of the procedure of the batting number counting method (hitting number generating process) performed by the batting number calculating apparatus 2. The batting number calculating apparatus 2 executes the batting number calculating process according to the procedure of the flowchart of FIG. 3 by executing the batting number calculating program 300 stored in the storage unit 30. Needless to say, the present invention includes a program for executing the counting method described below using the above-described counting system 1.

  In FIG. 3, the batting number calculation device 2 starts the batting number counting method when receiving a batting count start command by the player operating the operation unit 150 of the display device 3 or the like. When the hit count method is started, first, it is determined whether or not the player has moved the hole based on the hole data 390 in the storage unit 30 and the current location information of the player by the GPS unit 50 (step S11).

  When it is determined that the hole has been moved (Yes in step S11), the batting number counting unit 10 and the count processing unit 20 of the batting number calculating apparatus 2 reset the counter (step S25). If the movement of the hole is not detected (No in step S11), the process stands by without doing anything until the swing detection 1 in step S12.

  The determination of whether or not there has been a hole movement is an indispensable step when moving to the second hole after moving to the second hole after the round of the first hole is completed, but is performed at the first hole immediately after the start of the round. You don't have to. In this case, the counter may be set so as to be reset when a strike count start command is received, or set so that the counter is zero when the strike count starts.

  After the count is reset, the swing detection unit 12 of the hit counting unit 10 acquires sensing data from the output of the inertial sensor of the inertial measurement unit 110. By performing calculations using the acquired sensing data, GPS data obtained from the detection result of the GPS unit 50, and geomagnetic data obtained from the geomagnetic sensor 60, a swing of the golf club 90 of the player ("Swing 1") is performed. When detected (step S12), the hit count value detection unit 16 counts the hit count value 1 based on the detection result of the swing, and the count value 1 is sent to the hit count value acquisition unit 21 of the count processing unit 20. Obtained and added to the sensing data table 310 of the storage unit 30 in time series.

  Next, the count processing unit 20 determines whether or not the count value 1 acquired by the hit count value acquisition unit 21 should be counted as the number of hits by the player. In other words, the count processing unit 20 determines whether or not the swing ("Swing 1") detected by the swing detection unit 12 in the swing detection 1 of step S12 and counting the count value 1 is the number of hits by the player. judge. In the present embodiment, whether or not the count value 1 is the number of hits is determined based on whether or not the follow-through stationary time in the player's swing detected by the swing detection unit 12 exceeds a threshold value. In other words, when “Swing 1” is a “shot” swing in which the number of hits is a strike, the follow-through rest time (holding time) is longer than when the “swing” swing is a simple swing. By setting a threshold value for the stationary time of the follow-through of the swing, the swing having the stationary time exceeding the threshold value can be determined to be a “shot” swing that can be counted as the number of hits.

  Here, the follow-through in the swing path can be detected by the inertial sensor of the inertial measurement unit 110 attached to the golf club 90. Here, the detection result by the inertial sensor is output with time information. Therefore, the follow-through holding time can be known from the time information attached to the detection data of the inertial sensor.

  When the rest time of the follow-through is longer than the threshold (Yes in step S13), the count processing unit 20 determines that the count value 1 is the number of hits by the player and counts plus one hit (step S14). If the stationary time is shorter than the threshold (No in step S13), the process proceeds to step S15 where the next swing is detected without adding the number of hits.

  Next, the swing of the player (“Swing 2”) is detected by performing an operation using the sensing data acquired from the output of the inertial sensor of the inertial measurement unit 110, the GPS data, and the geomagnetic data. Then (step S15), the hit count value detection unit 16 counts the hit count value 1 based on the detection result of the swing 2, and the count value 1 is acquired by the hit count value acquisition unit 21 of the count processing unit 20. And added to the sensing data table 310 of the storage unit 30 in time series.

  Next, as in step S13, the count processing unit 20 determines whether or not the swing 2 is counted as the number of hits by checking whether or not the follow-through rest time in the swing 2 of the player has exceeded a threshold value. Determine. When the follow-through rest time is longer than the threshold value (Yes in step S16), the count processing unit 20 determines that the count value 1 of swing 2 is the number of hits by the player and counts plus one hit (step S17). If the follow-through stationary time is shorter than the threshold (No in step S16), the process proceeds to step S20.

  Next, the count processing unit 20 detects the “swing 1” detected by the swing detection 1 in step S12 and is determined to be a shot in step S13, and the swing detection 2 in step S15. It is determined whether or not there has been a movement within a given condition range, specifically, whether or not a player has moved more than a predetermined distance between “swing 2” determined to be present (step) S18). If there is a movement of a predetermined distance or more between the swing 1 of the swing detection 1 and the swing 2 of the swing detection 2 (Yes in step S18), the process advances to the next step S19 while keeping the count of hits.

  When there is no movement of a predetermined distance or more between the swing 1 of the swing detection 1 and the swing 2 of the swing detection 2, and the swing 2 is performed at substantially the same position as the swing 1 (No in step S18), It can be determined that the golf ball is OB (Out of Bounds) due to the shot by swing 1, which goes out of the play area. In other words, it can be determined that the OB was re-attacked by the swing 2 from the same point as the swing 1 because of the OB. In the case of OB, a one-stroke penalty is given and one stroke is added, and swing 2 which is a re-attack of swing 1 is the third stroke. Accordingly, when there is no movement of a predetermined distance or more between swing 1 and swing 2 (when hitting at approximately the same position) (No in step S18), +1 hit is counted (step S26), and then step S19. Proceed to

  Next, in step S19, it is confirmed whether or not manual correction is required for the number of hits counted so far. For example, as a routine of the batting number calculation program 300, the player is notified by the character display, voice, vibration, etc. of the display device 3 when it is time to determine whether or not manual correction is necessary.

  The case where it is necessary to perform manual correction is, for example, when the swing 1 detected by the swing detection 1 in step S12 or the swing 2 detected by the swing detection 2 in step S15 is swung with a swing that is intended to be hit Or, when the ball moves after the address and continues to play after replacement, the above-mentioned steps S11 to S18 (step S26) cannot be counted correctly.

When it is necessary to perform manual correction (Yes in step S19), for example, the count value is added or subtracted (input of the count adjustment value) by the operation unit 150 of the display device 3 (count adjustment value input) (step correction). S27).
If it is not necessary to perform manual correction (No in step S19), the process proceeds to step S20.

  Next, in step S20, it is determined whether or not to finish counting the number of hits, that is, whether or not to end the play. When the play (counting of hits) is continued (No in step S20), the process returns to step S11. When the play (batting count) is to be ended (Yes in step S20), a series of hit counting methods (batting count calculation method) is ended.

As described above, according to the counting system 1 according to the present embodiment and the counting method (battage calculation method) using the counting system 1, the following effects can be obtained.
In this embodiment, the swing detection unit 12 uses the sensing data acquired from the output of the inertial sensor of the inertial measurement unit 110, the GPS data obtained from the detection result of the GPS unit 50, and the geomagnetic data obtained from the geomagnetic sensor 60. By performing the calculation, the player's swing of the golf club 90 (“Swing 1”) was detected, and the hit count value 1 was counted. In the same manner, the next swing “Swing 2” was detected, and the hit count value 2 was counted.

  Then, it is determined whether or not the player has moved a predetermined distance or more between the swing 1 and the swing 2, and when there is no movement more than the predetermined distance, the hit number adjustment unit 255 adjusts the hit number. It was. As a specific example of adjusting the number of hits, when the swing 2 is performed at substantially the same position as the swing 1, for example, an OB in which a golf ball goes out of the play area by a shot by the swing 1, Judging from the same point that swing 2 was re-attacked, one OB penalty was added to the number of strokes.

  According to this embodiment, based on the swing detection result detected by the inertial sensor and the GPS data including the positioning data at the time corresponding to the swing detection result, it is possible to accurately perform the operation such as inputting the count value. Thus, it is possible to provide a counting system 1 capable of performing accurate counting.

Further, according to the present embodiment, it is confirmed whether or not the follow-through holding time in the swing trajectory of the player exceeds a threshold value, and when the threshold value is exceeded, the swing is a “shot” in which the number of hits is a hit. In the case where the swing is below the threshold, the swing is determined to be “swing” that is not the number of hits.
According to this, it is possible to contribute to the accurate counting of the number of hits.

Moreover, the count system 1 of this embodiment has the display apparatus 3 as a display terminal provided with the display part 170 etc. which display a count result.
Thereby, it is possible to play while checking the counting result of the number of hits by the counting system 1 in real time.

  Further, the display device 3 includes an operation unit 150 that functions as an input unit that inputs an adjustment value of the number of strokes of the number-of-bats adjustment unit 255 of the number-of-bats calculation device 2.

And in this embodiment, it includes step S19 which confirms whether it is necessary to perform manual correction with respect to the counted number of hits, and when it is necessary to perform manual correction, addition of the count value or It is configured to perform count correction input (input of count adjustment value) for subtraction.
Thereby, the count value of the number of hits is adjusted when there is a given relationship between the position of the player at the time corresponding to the detection result of the swing detection 1 and the position of the player at the time corresponding to the detection result of the swing detection 2. In the counting system 1 of this embodiment, when an unexpected situation of the given relationship occurs, the adjustment value can be input manually. Therefore, even when an unexpected situation occurs, it is possible to provide the count system 1 that can leave an accurate count result of the number of strokes.

(Embodiment 2)
Next, a second embodiment of the method for counting the number of hits by the player will be described with reference to the drawings. FIG. 4 is a flowchart showing the procedure of a batting number counting method (batting number calculation method) according to the second embodiment. As in the first embodiment, the counting method using the counting system 1 shown in FIGS. 1 and 2 will be described. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and duplicated. The description to be omitted is omitted.

  In the method of counting the number of strokes of the second embodiment shown in FIG. 4, the determination method for determining whether or not to count the number of strokes in swing 1 performed after swing detection 1 in step S12 (step S33), and the number of strokes of swing 2 performed after swing detection 2 in step S15. The configuration is the same as the counting method of the number of strokes of the first embodiment shown in FIG. Therefore, the description will focus on the determination method for determining whether or not the number of strikes of the swing can be counted in steps S33 and S36.

  In step S <b> 12 shown in FIG. 4, the swing detection unit 12 of the batting number counting unit 10 performs an operation using the sensing data acquired from the output of the inertial sensor of the inertial measurement unit 110, GPS data, and geomagnetic data, When the player's swing ("Swing 1") is detected and the hit count value 1 is counted, the count processing unit 20 next determines whether or not the count value 1 should be counted as the player's hit count. Determine. In the present embodiment, whether or not the count value 1 is the number of hits is determined by whether or not there is an impact exceeding the threshold during the swing of the player detected by the swing detection unit 12. In other words, when “swing 1” is a “shot” swing in which the number of hits is the number of hits, a predetermined impact is detected at a predetermined timing during the swing of the golf club 90. On the other hand, since there is almost no impact or a very small impact (for example, the peak of the wind pressure applied to the club face of the golf club 90 or the shaft 93) at the time of a simple “swing” swing, it is detected at a predetermined timing during the swing. By detecting an impact equal to or greater than the threshold value, it is possible to clearly determine that the swing is a “shot” swing that can be counted as the number of hits.

  Here, the impact during the swing can be detected by the inertial sensor of the inertial measurement unit 110 attached to the golf club 90, and the timing of the impact during the swing is based on the time information attached to the detection data of the inertial sensor. I can know.

  When the impact exceeding the threshold is detected during the swing (Yes in Step S33), the count processing unit 20 determines that the count value 1 is the number of hits by the player and counts plus one hit (Step S14). If the impact during one swing is below the threshold or not (No in step S33), the process proceeds to step S15 where the next swing is detected without adding the number of hits.

  In a similar manner, during the swing of “Swing 2” detected by the swing detection 2 of step S15, depending on whether or not there is an impact exceeding the threshold, the swing of “shot” where “Swing 2” is the number of hits It can be determined whether or not there has been. When the impact exceeding the threshold is detected during the swing of swing 2 (Yes in step S36), the count processing unit 20 determines that the count value is the number of hits by the player and counts plus one stroke (step S17). If the impact during swing of swing 2 is below the threshold or not (No in step S36), the process proceeds to step S20.

  Note that a plurality of impact threshold values set in the above-described impact detection may be set as necessary. For example, since the impact detected when the swing is a swing is almost negligible or very small, if the impact threshold of the swing is set and the impact falls below that threshold, the swing is a swing Can be determined. Similarly, between the above-mentioned “shot” impact threshold and “impact” impact threshold, the “approach shot” impact threshold, which is weaker than the “shot” impact, and the “approach shot” By having in the impact reference data 380 of the storage unit 30 an impact threshold value of “Putter” that is even weaker than the impact threshold value, the type of shot is specified from the impact detection result by the impact detection unit 14. Can be remembered.

As described above, according to the batting number counting method of the second embodiment, when an impact exceeding a threshold is detected during a swing, it is determined that the swing count value is the batting number of the player and plus one hit is made. Counting is performed, and if the impact during the swing is below the threshold or not, it is determined that the swing is not counted in the number of hits.
According to this configuration, it is possible to accurately count the number of hits by excluding swings that are not counted, such as swinging, according to the strength and timing of impact in the swing of the golf club 90.

  The embodiment of the present invention made by the inventor has been specifically described above, but the present invention is not limited to the above-described embodiment, and various modifications are made without departing from the scope of the present invention. Is possible.

  For example, in the above-described embodiment, the number of hits in the golf round has been described in detail, but the present invention is not limited to this. For example, the counting system 1 and the counting method of the above embodiment can be applied to a golf competition that is not an official round or putter golf.

  Further, the counting system and the counting method of the present invention are not limited to application to golf. The present invention can also be applied to other sports that count hits with a hitting tool, and can be used, for example, to count the number of hits in baseball hitting practice.

  In the above embodiment, the time information from the GPS unit 50 attached to the data related to the state of the swing and the data related to the impact output from the swing detection unit 12 and the impact detection unit 14 is not necessarily the same as the detection time of the impact. Not. The time information may deviate from the impact detection time within the same swing period.

  In the above embodiment, the hit number information is displayed on the display device 3 of the player. However, the hit number information may be transmitted to the score management device and used for score management and recording. The score management device may be an independent device or may be integrated with at least one of the striking number calculation device 2 and the display device 3.

Moreover, in the said embodiment, although it was set as the structure which uses the GPS unit 50 as a positioning apparatus which measures the position of a player, it is not restricted to this.
For example, a counting system using a so-called beacon that performs positioning by receiving radio waves or electromagnetic waves emitted from a radio station or the like installed at a golf course by a receiver, or other positioning systems using short-range communication, etc. Can also be configured.

  Further, in the first embodiment, it is confirmed whether or not the follow-through holding time in the swing path of the player exceeds a threshold value. If the threshold value is exceeded, the swing is a “shot” in which the number of hits is a hit. Judged. In the second embodiment, when an impact exceeding a threshold is detected during a swing, the swing count value is determined to be the number of hits by the player, and plus one hit is counted. In the present invention, when the follow-through holding time exceeds the threshold value and an impact exceeding the threshold value is detected during the swing, the swing count value is determined to be the number of hits by the player, and plus one hit is counted. The structure to be included is included.
