It was necessary to keep it in a detectable state. However, despite the short swing time, golf rounds often last from half a day to one day. If the inertial sensor can always be detected for such a long time, the amount of wasted power (power consumption) required for measurement other than the actual swinging time may increase. There has been a problem that the measurement data measured by the inertial sensor becomes a huge amount of data.

FIG. 2 is a diagram illustrating a sensor unit as a motion measurement device and a swing analysis device as a motion analysis device according to the first embodiment. FIG. 3 is a diagram illustrating an example of the mounting position and orientation of the sensor unit.

  As shown in FIG. 1, the swing analysis system 1 of the first embodiment includes a sensor unit (an example of a motion sensor including an inertial sensor) 10 as a motion measurement device and a swing analysis device 20 as a motion analysis device. As shown in FIG. 1, the swing analysis system 1 includes a GPS satellite (position information output unit) 8 and a position information acquisition unit 43 (see FIG. 6) included in the swing analysis device 20. 8 includes a function of receiving information related to a position included in the radio wave (satellite signal) from 8 and performing positioning calculation (acquisition of position information). Communication between the sensor unit 10 and the swing analysis device 20 may be wireless communication or wired communication. As shown in FIG. 2, the swing analysis device 20 is a personal computer 20 a, a portable device 20 b such as a smartphone or a tablet, or various information such as a wearable terminal such as a head mounted display (HMD) or a wrist device. This is realized by a terminal (client terminal).

  The swing analysis system 1 may be configured to include a swing diagnosis device 30 separately from the swing analysis device 20. However, the swing diagnosis device 30 may be included in the swing analysis device 20. The swing diagnosis apparatus 30 may be realized by a server that processes a request from the swing analysis apparatus 20. The swing analysis device 20 and the swing diagnosis device 30 may be connected via the network 40. The network 40 may be a wide area network (WAN) such as the Internet or a local area network (LAN). Alternatively, the swing analysis device 20 and the swing diagnosis device 30 may communicate without going through the network 40 by, for example, short-range wireless communication or wired communication.

  The sensor unit 10 can measure, for example, accelerations in the directions of three axes that are orthogonal to each other, angular velocities around the axes of the three axes that are orthogonal to each other, and directions (directions) that the sensor unit 10 faces, for example. As shown in FIG. 2, it is attached to, for example, a golf club 3 as an exercise device. Based on the output of the sensor unit 10, the swing analysis apparatus 20 performs the state of the user 2, for example, “moving” moving to go to the next shot position in the round, or performing a swing (shot). It can be obtained as movement information (position information) such as “stopping” or “movement stop”.

  For example, as shown in FIG. 3, the sensor unit 10 has three detection axes (x-axis, y-axis, z-axis) intersecting each other (ideally orthogonal to each other) so as to be aligned with each other. One example) is attached to 3. In FIG. 3, for example, the y axis is aligned with the longitudinal direction of the shaft of the golf club 3 (longitudinal direction of the golf club 3), and the x axis is aligned with the target direction of the hit ball (the hit target direction). It is attached. Preferably, the sensor unit 10 is attached at a position close to a grip that is difficult to receive an impact at the time of hitting a ball and is difficult to receive a centrifugal force during a swing. The shaft is a portion of the handle excluding the head (striking portion) 3a of the golf club 3, and includes a grip. However, the sensor unit 10 may be attached to a part of the user 2 (for example, a hand or a glove), or may be attached to an accessory (portable device) such as a wristwatch.

  The user 2 performs a swing motion by hitting the golf ball 4 (shot) or a swing motion by swinging according to a predetermined procedure. Note that this swing motion is, for example, a swing motion performed at a practice field or a swing motion during a round at a golf course. In any case, such a swing operation is generally performed in a state in which the current position of the user 2 is not moving, that is, a so-called “stopped” state.

  FIG. 4 is a diagram showing a procedure of operations performed until the user 2 hits the ball in the present embodiment. As shown in FIG. 4, the user 2 first performs an input operation such as information related to the body of the user 2 and information (golf club information) regarding the golf club 3 used by the user 2 via the swing analysis device 20 ( S1).

  In step S1 of FIG. 4, the user 2 inputs information related to the body such as height, gender, age, country on the input screen (not shown), and the golf club such as club length (shaft length), count, etc. Enter the information. The information related to the body is not limited to this, and may include, for example, information on at least one of the length of the arm and the length of the leg instead of the height or together with the height. Similarly, the information included in the information on the golf club is not limited to this. For example, the golf club information may not include information on either the club head or the count, or may include other information. .

  Next, the user 2 performs a measurement start operation (operation for causing the sensor unit 10 to start measurement) via the swing analysis device 20 (S2). The user 2 receives a notification (for example, a voice notification) instructing to take the address posture (basic posture before the start of the swing) from the swing analysis device 20 (S3 is Y), and then the longitudinal direction of the shaft of the golf club 3 Takes the attitude of the address so as to be perpendicular to the target line (the target direction of the hit ball), and stops still for a predetermined time (S4). Next, after receiving notification (for example, notification by voice) that permits the swing from the swing analysis device 20 (S5 is Y), the user 2 performs a swing motion and hits the golf ball 4 (S6). The present embodiment is not necessarily limited to hitting a ball, but can also be applied to swinging and may have a function of detecting timing corresponding to a hit ball.

  When the user 2 performs the measurement start operation in step S2 in FIG. 4, the swing analysis apparatus 20 transmits a measurement start command to the sensor unit 10, and the sensor unit 10 receives the measurement start command and receives the measurement start command in the inertial sensor (motion sensor). Start measuring triaxial acceleration and triaxial angular velocity. The sensor unit 10 measures the triaxial acceleration and the triaxial angular velocity at a predetermined measurement sampling rate (for example, 1 kHz, in other words, a predetermined period of 1 ms), and sequentially transmits the measured data to the swing analysis device 20.

  The swing analysis device 20 notifies the user 2 of the permission to start the swing shown in step S5 of FIG. 4, and then the swing motion in which the user 2 hits the golf club 3 based on the measurement data of the sensor unit 10. (Step S6 in FIG. 4) is analyzed.

  As shown in FIG. 5, the swing operation performed by the user 2 in step S <b> 6 in FIG. 4 starts after the swing (back swing) is started from the address posture (stationary state), and then the shaft of the golf club 3 is leveled during the back swing. The halfway back, the top switching from the backswing to the downswing, and the halfway down in which the shaft of the golf club 3 becomes horizontal during the downswing, and the action to hit the golf ball 4 (hit) Contains. Then, the swing analysis device 20 generates swing analysis data including the time (date and time) when the swing was performed, the identification information and sex of the user 2, the type of the golf club 3, and information on the analysis result of the swing motion, and the network 40 (See FIG. 1) to transmit to the swing diagnosis apparatus 30.

  The swing diagnosis device 30 receives and stores the swing analysis data transmitted from the swing analysis device 20 via the network 40. Therefore, every time the user 2 performs a swing motion according to the procedure of FIG. 4, the swing analysis data generated by the swing analysis device 20 is stored in the swing diagnosis device 30, and a swing analysis data list is constructed.

  In the present embodiment, when the user 2 activates the swing diagnosis application via the operation unit 23 (see FIG. 6) of the swing analysis device 20, the swing analysis device 20 communicates with the swing diagnosis device 30, and the swing analysis device 20. A swing analysis data selection screen (not shown) is displayed on the display unit 25 (see FIG. 6). This selection screen shows the time (date and time), the type of golf club 3 used, and the analysis result of the swing for each swing analysis data of the user 2 included in the swing analysis data list stored in the swing diagnosis device 30. Contains some indicator values.

  In addition, the selection screen includes a check box associated with each swing analysis data, and the user 2 checks one of the check boxes by operating the swing analysis apparatus 20 to check the swing analysis apparatus. For example, an input data editing screen (not shown) to be subjected to swing diagnosis is displayed on the display unit 25 of 20. The input data editing screen includes, as initial values, values obtained on the basis of the selected swing analysis data for each gender, golf club 3 type (whether it is a driver or an iron), and each swing index. It is.

  On the input data editing screen, the input data including the gender, the type of the golf club 3 and each index value can be edited, and the user 2 can input via the operation unit 23 (see FIG. 6) of the swing analysis device 20. You can edit the data. Also, the user 2 can input, for example, a golf score for each hole as input data from the input data editing screen.

  The swing diagnosis apparatus 30 receives this input data (input result), and calculates the levels of a plurality of items using the input data. For example, the swing diagnosis apparatus 30 may calculate the level for each item of “V zone”, “rotation”, “speed”, “impact”, “swing tempo”, and “swing efficiency”. The “level” may be expressed by a score such as “1, 2, 3, 4, 5”, for example.

  The swing analysis device 20 receives information on the levels and total points of a plurality of items, and causes the display unit 25 to display a swing diagnosis screen. As an example of swing diagnosis, the user 2 can grasp the levels and total points of a plurality of items as diagnosis results for input data using the swing diagnosis screen. In particular, the user 2 can grasp the strengths and weaknesses of his / her swing from the swing diagnosis screen. In addition, the user 2 can grasp, for example, which index should be improved to overcome the weak point.

1-3. Swing analysis method 1-3-1. Form 1 of procedure related to swing analysis method
Next, Form 1 of the procedure relating to the swing analysis method will be described with reference to FIGS. 7 and 8. FIG. 7 is a flowchart showing a first form of the procedure of the swing analysis method. FIG. 8 is a timing chart relating to the change of the storage sampling rate in the first embodiment. Here, the above-described processing unit 21 executes the swing analysis process according to the procedure of the flowchart illustrated in FIG. 7, for example, by executing the swing analysis program 240 and the sampling rate control program 241 stored in the storage unit 24. Hereinafter, it demonstrates along the flowchart of FIG. In addition, the element which comprises the swing analysis system 1 mentioned above is demonstrated using a same sign.

  First, the processing unit 21 stands by until a measurement start operation by the user 2 (operation in step S2 in FIG. 4) is performed, and when the measurement start operation is performed, a predetermined measurement sampling rate (period of 1 ms in the above example) is performed. Then, measurement data measurement by the sensor unit 10 and reception of information relating to a position included in the radio wave (satellite signal) from the GPS satellite 8 are started. The measurement data measured here and the information related to the received position are transmitted to the data acquisition unit 210 and the exercise information acquisition unit 42.

  The exercise information acquisition unit 42 acquires the transmitted measurement data in the sensor unit 10 (step S110). The position information acquisition unit 43 acquires information related to the position included in the transmitted radio wave (satellite signal) from the GPS satellite 8.

  The data acquisition unit 210 acquires the transmitted measurement data and information related to the position, and measures at a storage sampling rate (for example, 32 Hz: 31.25 ms) lower than the measurement sampling rate (1 kHz: 1 ms cycle). Information related to data and position is stored (step S120).

  Next, based on the measurement data in the sensor unit 10 acquired by the exercise information acquisition unit 42 in step S110 and the information related to the position acquired by the position information acquisition unit 43, the movement information acquisition unit 28 acquires the position information of the user 2. Alternatively, the movement information is acquired (step S130) and transmitted to the processing unit 21.

  Next, based on at least one of the position information and the movement information transmitted from the movement information acquisition unit 28, the processing unit 21 is in a “movement stop” state in which the user 2 remains at a certain position. Is determined (step S140). In general, the swing motion in golf is often performed in a so-called “stopped” state in which the current position of the user 2 is not moving. Therefore, the state of “stopping”, that is, the state of “moving stop” in which the user 2 stays at a certain position means that, for example, during a round at a golf course, a shot will be performed from now on ( It can be assumed that this is a scene where a swing motion is performed) or a scene where a swing motion is performed in a practice field.

  Here, when it is determined in step S140 that the state is the “movement stop” (step S140: Yes), the processing unit 21 (sampling rate control unit 216) assumes that a shot (swing operation) will be performed from now. Then, as shown in FIG. 8, the data acquisition unit 210 is instructed to increase the storage sampling rate to, for example, (1 kHz: period 1 ms). The data acquisition unit 210 that has received an instruction from the processing unit 21 (sampling rate control unit 216) stores the transmitted measurement data at a storage sampling rate (1 kHz: period 1 ms) (step S150).

  Here, when it is determined in step S140 that the state is not “moving stop”, that is, “moving” (step S140: No), the processing unit 21 (sampling rate control unit 216) performs a shot (swing operation). It is determined that the state is not performed, and the process returns to step S110. Then, a series of procedures after the measurement data measurement at the sensor unit 10 at a predetermined measurement sampling rate and the reception of information relating to the position included in the radio wave (satellite signal) from the GPS satellite 8 are continued are repeated.

  Next, the processing unit 21 determines whether or not there is an instruction to end the measurement (step S160). When there is an instruction to end the measurement (step S160: Yes), the series of procedures is ended. If there is no instruction to end the measurement (step S160: No), the process returns to step S110 to measure the measurement data in the sensor unit 10 at a predetermined measurement sampling rate and to the radio wave (satellite signal) from the GPS satellite 8. A series of procedures after continuing reception of information relating to the included position is repeated, and when there is an instruction to end measurement (step S160: Yes), the series of procedures is terminated.

  According to the first form of the procedure relating to the swing analysis method described above, it is determined whether or not the vehicle is moving based on, for example, position information and / or movement information acquired by the movement information acquisition unit 28, and the determination As a result, the storage sampling rate at which the storage unit 24 stores the outputs of the inertial sensors (the acceleration sensor 12 and the angular velocity sensor 13) is changed. Accordingly, the storage sampling rate at which the storage unit 24 stores the output (output data) of the inertial sensor without setting the inertial sensor in motion to a state where detailed detection is always possible or a state where the detected data can be stored is set. When it is necessary to always store the output data of the inertial sensor at a high sampling rate in the state where the movement (swing movement) is actually performed, and the movement (swing) is actually performed This can be changed depending on the case where the output of the inertial sensor (output data) is not so necessary in the absence of power, reducing the amount of power required for measurement (power consumption) and reducing the amount of stored measurement data be able to.

1-3-2. Form 2 of procedure related to swing analysis method
Next, Form 2 of the procedure related to the swing analysis method will be described with reference to FIGS. 9 and 10. FIG. 9 is a flowchart showing the second form of the procedure of the swing analysis method. FIG. 10 is a timing chart relating to the change of the storage sampling rate in the second mode. Here, the above-described processing unit 21 executes the swing analysis process according to the procedure of the flowchart illustrated in FIG. 9, for example, by executing the swing analysis program 240 and the sampling rate control program 241 stored in the storage unit 24. Hereinafter, description will be given along the flowchart of FIG. In addition, the element which comprises the swing analysis system 1 mentioned above is demonstrated using a same sign.

  First, the processing unit 21 stands by until a measurement start operation by the user 2 (operation in step S2 in FIG. 4) is performed. When the measurement start operation is performed, a measurement sampling rate that is set low (for example, 32 Hz: cycle) 31.25 ms), measurement data measurement by the sensor unit 10 and reception of information relating to the position included in the radio wave (satellite signal) from the GPS satellite 8 are started. The measurement data measured here and the information related to the received position are transmitted to the data acquisition unit 210 and the exercise information acquisition unit 42.

  The exercise information acquisition unit 42 acquires measurement data in the sensor unit 10 that is measured and transmitted at a low measurement sampling rate (step S210). The position information acquisition unit 43 acquires information related to the position included in the transmitted radio wave (satellite signal) from the GPS satellite 8.

  In addition, the data acquisition unit 210 acquires the transmitted measurement data and information related to the position, and stores the measurement data and information related to the position at a low storage sampling rate (for example, 32 Hz: period 31.25 ms). (Step S220).

  Next, the movement information acquisition unit 28 is based on the measurement data in the sensor unit 10 acquired by the exercise information acquisition unit 42 in step S210 and the information related to the position acquired by the position information acquisition unit 43. Alternatively, the movement information is acquired (step S230) and transmitted to the processing unit 21.

  Next, as in the first mode, the processing unit 21 performs “movement stop” in a state where the user 2 remains at a certain position based on at least one of the position information and the movement information transmitted from the movement information acquisition unit 28. It is determined whether or not it is in the state (step S240). In addition, the description about the same content as the form 1 is abbreviate | omitted.

  Here, when it is determined in step S240 that the state is the “movement stop” state (step S240: Yes), the processing unit 21 (sampling rate control unit 216) assumes that a shot (swing operation) will be performed from now. Then, as shown in FIG. 10, the sensor unit 10 is instructed to increase the measurement sampling rate to, for example, (1 kHz: period 1 ms). Upon receiving the instruction, the sensor unit 10 performs measurement by increasing the measurement sampling rate to, for example, (1 kHz: period 1 ms), and acquires the output of the inertial sensor by the motion information acquisition unit 42 (step S250).

  Next, the exercise information acquisition unit 42 transmits output data measured at a high measurement sampling rate to the data acquisition unit 210, and the data acquisition unit 210 converts the transmitted measurement data into a high storage sampling rate (1 kHz: The data is stored with a period of 1 ms (step S260).

  Here, when it is determined in step S240 that the state is not “moving stop”, that is, “moving” (step S240: No), the processing unit 21 (sampling rate control unit 216) performs a shot (swing operation). It is determined that the state is not performed, and the process returns to step S210.

  Next, the processing unit 21 determines whether or not there is an instruction to end the measurement (step S270). If there is an instruction to end the measurement (step S270: Yes), the series of procedures is ended. If there is no instruction to end the measurement (step S270: No), the process returns to step S210, and the measurement data in the sensor unit 10 is measured at a predetermined measurement sampling rate, and the radio wave (satellite signal) from the GPS satellite 8 is transmitted. A series of procedures after continuing reception of information relating to the included position is repeated, and when there is an instruction to end measurement (step S270: Yes), the series of procedures is terminated.

  According to Form 2 of the procedure relating to the swing analysis method described above, the stored sampling rate can be easily changed by changing the measurement sampling rate measured by the inertial sensor in accordance with at least one of the position information and the movement information. can do. As a result, the storage sampling rate at which the output (output data) of the inertial sensor is stored in the storage unit 24 can be stored at a high sampling rate at all times while the exercise (swing operation) is actually performed. The power required for measurement can be changed depending on whether it is necessary to maintain a stable state, or when there is no need to memorize the output data of the inertial sensor when there is no actual movement (swing) The amount (power consumption) can be reduced, and the amount of measurement data stored can be reduced.
