[0022] An example of the present disclosure will be described below with reference to the accompanying drawings. The following description is merely exemplary in nature and does not limit the present disclosure, its applications, and uses. The accompanying drawings are schematic drawings, and the illustrated configuration and actual products may differ in dimensional ratios, etc.

[0023] A measurement system 1 according to one embodiment of the present disclosure is configured to measure the displacement of whips used by all jockeys and the positions of all horses in any horse race. Specifically, as shown in FIG. 1, the measurement system 1 includes a displacement measurement unit 10 and a position measurement unit 20.

[0024] In this embodiment, as shown in Fig. 1, the measurement system 1 includes a determination device 2 including an acquisition unit 30 and a determination unit 40, a communication device 3, and a display device 4. The display device 4 is an example of a notification unit. The determination device 2, the communication device 3, and the display device 4 may be configured as different devices connected via a communication network or the like, or may be configured as a single device that includes the functions of the determination device 2, the communication device 3, and the display device 4.

[0025] A position measurement unit 20 is provided on each of the horses 100. While FIG. 1 shows an example in which there are two horses 100, this is not limiting. Each horse 100 is ridden by a jockey. Each jockey uses a whip 110 equipped with a displacement measurement unit 10. Hereinafter, the two horses 100 will be referred to as a first horse 101 and a second horse 102, respectively, and the whip 110 used by the jockey of the first horse 101 will be referred to as a first whip 111, and the whip 110 used by the jockey of the second horse 102 will be referred to as a second whip 112.

[0026] Each whip 110 is provided with a communication unit 31, and each horse 100 is provided with a communication unit 32. The communication units 31, 32 are configured with a communication circuit or communication module for transmitting and receiving data to and from the communication device 3. The communication unit 31 is provided, for example, in the grip of the whip 110 or in a portion of the shaft adjacent to the grip. Hereinafter, the communication unit 31 capable of outputting the displacement amount of the whip 110 measured by the displacement measuring unit 10 of the first whip 111 may be referred to as the first communication unit 311, and the communication unit 31 capable of outputting the displacement amount of the whip 110 measured by the displacement measuring unit 10 of the second whip 112 may be referred to as the second communication unit 312. In other words, the measurement system 1 of this embodiment includes the first communication unit 311 and the second communication unit 312. The communication unit 32 is attached, for example, to the saddle or bib of the horse 100. The whip 110 is, for example, less than 77 cm in length and has a grip that is held by the jockey, a tip provided with a shock absorbing material, and a shaft connecting the grip and the tip.

[0027] The displacement measuring unit 10 is attached to a whip 110 used by the jockey and is configured to be able to measure the amount of displacement of the attached whip 110. The displacement measuring unit 10 is configured, for example, as a displacement measuring sensor and is fixed to the shaft of the whip 110 with adhesive tape or the like. The displacement measuring sensor is configured, for example, to be able to detect at least one of bending displacement and torsional displacement of the shaft. The measured amount of displacement of the whip 110 is output to the determination device 2 via the communication unit 32.

[0028] The position measurement unit 20 includes a position measurement sensor such as a GPS sensor, and is configured to be able to measure the position of the horse 100 ridden by the jockey when the displacement measurement unit 10 measures the displacement of the whip 110. The position measurement unit 20 is attached, for example, to the saddle or bib of the horse 100. The measured position of the horse 100 is output to the determination device 2 via the communication unit 31.

[0029] The determination device 2 includes, for example, a processor 201 and a storage unit 202. The acquisition unit 30 and the determination unit 40 are realized, for example, by the processor 201 executing a predetermined program stored in the storage unit 202. The processor 201 includes, for example, a CPU, an MPU, a GPU, a DSP, an FPGA, an ASIC, or a combination thereof. The storage unit 202 includes, for example, a non-transitory computer-readable storage medium constituted by an internal storage medium or an external storage medium. The internal storage medium includes a non-volatile memory, etc. The external storage medium includes a hard disk (HDD), a solid-state drive (SSD), an optical disk device, etc.

[0030] The acquisition unit 30 is configured to be able to acquire, via the communication device 3, the displacement amount of the whip 110 measured by the displacement measurement unit 10 and the position of the horse 100 measured by the position measurement unit 20.

[0031] The determination unit 40 is configured to be able to determine whether or not a "whipping action" has been performed, in which the jockey swings the whip 110 so as to hit the horse 100, based on the acquired displacement of the whip 110 (in other words, whether or not the whip has been used, or whether or not the whip has been applied), based on the position of the horse 100 measured by the position measurement unit 20. In this embodiment, the determination unit 40 calculates the position of the horse 100 when it is determined that a "whipping action" has been performed.

[0032] For example, the determination unit 40 is configured to be able to determine a "whipping motion," a "practice motion," and "no motion" from the acquired displacement amount of the whip 110. A "practice motion" refers to the motion of the jockey swinging the whip 110 so as not to hit the horse 100 (e.g., a show whip). A "no motion" refers to a state in which the jockey is not swinging the whip 110. The determination unit 40 determines a "whipping motion," a "practice motion," and "no motion" as follows from differential data D(i) = A(i+1) - A(i) (D(last) = 0, A(i) = acquired raw data of the displacement amount of the whip 110, i = zero or a natural number) calculated from the acquired displacement amount of the whip 110. FIG. 2 shows an example of raw data A and differential data D when a "whipping motion" is performed. FIGS. 3 and 4 show an example of raw data A and differential data D when a "practice motion" is performed. FIG. 5 shows an example of raw data A and differential data D when a plurality of "whip-clap actions" and a plurality of "practice swing actions" are performed. If the absolute value of D(i) is greater than the first threshold value th_h (|D(i)|>th_h), the determination unit 40 determines that a "whiplash motion" has been performed. If the absolute value of D(i) is equal to or less than the first threshold value th_h and A(i) is greater than the absolute value of the second threshold value th_s (|D(i)|≦th_h and |A(i)|>th_s), the judgment unit 40 judges that a “practice swing” has been performed. If the absolute value of D(i) is equal to or less than the first threshold value th_h and A(i) is equal to or less than the absolute value of the second threshold value th_s (|D(i)|≦th_h and |A(i)|≦th_s), the judgment unit 40 judges that neither a “whip action” nor a “practice swing action” is being performed (i.e., “no action”).

[0033] The determination unit 40 may be configured to determine that a "practice swing" has been performed based on multiple determinations. For example, when the determination unit 40 determines that a "practice swing" has been performed for the first time, it determines whether or not the determination regarding the initial "practice swing" is correct. Whether or not the determination regarding the initial "practice swing" is correct is determined, for example, by making the same determination regarding the initial "practice swing" again. At this time, for example, the amount of displacement of the whip 110 obtained after the determination regarding the initial "practice swing" is made may be taken into consideration, or the determination result before the determination regarding the initial "practice swing" may be taken into consideration. When the determination regarding the initial "practice swing" is determined to be correct, the determination unit 40 determines that a "practice swing" has been performed. On the other hand, when the determination regarding the initial "practice swing" is not determined to be correct, the determination unit 40 changes the content of the determination based on the result of the second determination regarding the "practice swing."

[0034] FIG. 6 shows an example of the displacement of the whip 110 obtained when the jockey uses the whip 110 as shown in Table 1 below. [Table 1]

[0035] When the determining unit 40 determines that a "whip action" has been performed, whipping information including the number of times that a "whip action" has been determined to have been performed during the race and the position of the horse 100 when it was determined that a "whip action" has been performed is output to the display device 4 via the communication device 3. The display device 4 notifies the whipping information in a manner such as that shown in FIG. 7, for example. FIG. 7 shows a display screen 401 of the display device 4. One area of ​​the display screen 401 (for example, the left area of ​​FIG. 6) displays a course 402 of the racecourse where the race is being held. The other area of ​​the display screen 401 (for example, the right area of ​​FIG. 6) displays one of the horses 100 running in the race. In addition to the course 402, one area of ​​the display screen 401 displays a trajectory 403 of the horse 100 displayed in the other area of ​​the display screen 401, and a position 404 where it was determined that a "whip action" has been performed. In a corner 405 of the other area of ​​the display screen 401, the number of times it was determined that a "whip action" was performed during the race (for example, six times) is displayed.

[0036] The communication device 3 is configured with a communication circuit or a communication module for transmitting and receiving data. In this embodiment, the communication device 3 is located at a camera that shoots patrol video of the race, and is connected to the judgment device 2, the display device 4, and each of the communication units 31 and 32 via wired or wireless communication.

[0037] The display device 4 is configured to be able to display the position of the horse 100 when the jockey performs the whipping action. The display device 4 includes, for example, a stationary display device installed at a racecourse, and a wearable display device that can be worn by a jockey or the like.

[0038] An example of the measurement process executed when measuring a whipping motion with the measurement system 1 will be described with reference to Fig. 8. The measurement process shown in Fig. 8 is carried out, for example, by the processor 201 executing a predetermined program stored in the storage unit 202.

[0039] As shown in FIG. 8, when the measurement process starts, the acquisition unit 30 acquires the displacement of the whip 110 and the position of the horse 100 measured by the displacement measurement unit 10 and the position measurement unit 20 (step S1).

[0040] When the measured displacement of the whip 110 and the position of the horse 100 are acquired, the determination unit 40 determines whether or not a whipping action has been performed (step S2).

[0041] If it is determined that a whipping action has been performed (step S2=YES), the determination unit 40 calculates the position of the horse 100 when the whipping action was performed (step S3). After step S3, information about the whipping action, including the position of the horse 100 when the whipping action was performed, is output to the display device 4 via the communication device 3 (step S4).

[0042] After step S4, or if it is not determined that a "whiplash motion" has been performed (step S2=NO), the measurement system 1 determines whether or not a termination condition for terminating the measurement process is satisfied (step S5).

[0043] If it is determined that the termination condition is met (step S5=YES), the measurement process ends. If it is determined that the termination condition is not met (step S5=NO), the process returns to step S1, and the measured displacement of the whip 110 and the position of the horse 100 are acquired. The termination condition includes, for example, receipt of a signal indicating the end of the race or receipt of a command from the user to end the process.

[0044] The measurement system 1 can achieve the following effects.

[0045] The measurement system 1 comprises a displacement measurement unit 10 capable of measuring the amount of displacement of a whip 110 used by a jockey, and a position measurement unit 20 capable of measuring the position of the horse 100 ridden by the jockey when the amount of displacement of the whip 110 is measured by the displacement measurement unit 10. With this configuration, it is possible to realize a measurement system 1 that can more accurately measure the use of the whip 110 and measure the position of the horse 100 when the whip 110 is used. By measuring the position of the horse 100 when the whip 110 is used, the number of times the whip 110 is used can be managed.

[0046] The measurement system 1 includes a determination unit 40 that can determine whether or not a whipping action has been performed based on the measured displacement of the whip 110. With this configuration, the use of the whip 110 can be measured more accurately.

[0047] The determination unit 40 is configured to be able to determine whether the whipping action is a whipping motion, a practice swing, or no motion from the amount of displacement of the whip 110. With this configuration, the use of the whip 110 can be measured more accurately.

[0048] The measurement system 1 includes a display device 4 that can notify that a whipping action has been performed. With this configuration, spectators of the race can be provided with a better viewing experience.

[0049] The display device 4 is configured to be able to notify the number of whipping actions performed during one race. With this configuration, it is possible to provide a better viewing experience for spectators of the race.

[0050] The display device 4 is configured to be able to display the position of the horse 100 when the whipping action is performed. With this configuration, it is possible to provide spectators of the race with a better viewing experience.

[0051] The measurement system 1 includes a first communication unit 311 capable of outputting the displacement amount of the whip 110 measured by the displacement measuring unit 10 of the first whip 111, a second communication unit 312 capable of outputting the displacement amount of the whip 110 measured by the displacement measuring unit 10 of the second whip 112, and a communication device 3 connected by wireless communication to the first communication unit 311 and the second communication unit 312. The first communication unit 311 is attached to the first whip 111, and the second communication unit 312 is attached to the second whip 112. This configuration makes it possible to more accurately measure the use of the whip 110 and more reliably realize a measurement system 1 capable of measuring the position of the horse 100 when the whip 110 is used.

[0052] The communication device 3 is located at a camera that shoots patrol video of the race. This configuration shortens the distance between the communication device 3 and the first communication unit 311 and the second communication unit 312. As a result, the communication device 3 can communicate with the first communication unit 311 and the second communication unit 312 using a wireless communication standard with a short communication distance, such as Bluetooth.

[0053] The measurement system 1 can be configured as follows.

[0054] The position measurement unit 20 may be configured in any way that allows it to measure the position of the horse 100 when the displacement of the whip 110 is measured. For example, the position measurement unit 20 may be configured to be able to measure the position of the horse 100 when a whipping action is performed based on the time that has elapsed since the start of the race until it is determined that a whipping action has been performed. This makes it possible to more accurately measure the use of the whip 110 and more reliably realize a measurement system 1 that can measure the position of the horse 100 when the whip 110 is used.

[0055] The determination unit 40 may be configured in any way that can determine whether a whipping action, a practice swing, or no action is being performed. For example, the determination unit 40 may be configured to determine whether a whipping action, a practice swing, or no action is being performed using a trained model created by machine learning the relationship between the measured displacement of the whip 110 and each of the actions of the whipping action, the practice swing, and no action. This allows for more accurate measurement of the use of the whip 110 and more reliably realizes a measurement system 1 that can measure the position of the horse 100 when the whip 110 is used.

[0056] The determination device 2, communication device 3 and display device 4 may be configured as different devices connected, for example, by a communication network, or may be configured as a single device that includes the functions of the determination device 2, communication device 3 and display device 4.

[0057] The communication device 3 may be configured to output information about the whipping action to an external device other than the judging device 2, the display device 4, and the communication units 31 and 32. The external device may include, for example, a PC such as a server, or a mobile terminal such as a smartphone or tablet. This can provide spectators of the race with a better viewing experience.

[0058] The notification unit is not limited to being configured with the display device 4 that can provide visual notification. The notification unit may be configured with other devices that can notify the user of the whipping action using other senses, including sight, hearing, and touch.

[0059] The embodiments and modifications of the present disclosure can be combined with each other, or with modifications, or with each other. Features included in the embodiments and modifications of the present disclosure can also be combined with each other.
