[0022] An example of this disclosure is described below with reference to the attached drawings. The following description is essentially illustrative and does not limit this disclosure, its applications, or its uses. The attached drawings are schematic, and the illustrated configuration and actual product may differ in dimensional ratios, etc.

[0023] A measurement system 1 in one aspect of this disclosure is configured to measure the displacement of the whips used by all jockeys and the positions of all horses in any horse race. Specifically, as shown in Figure 1, the measurement system 1 comprises a displacement measuring unit 10 and a position measuring unit 20.

[0024] In this embodiment, as shown in Figure 1, the measurement system 1 comprises 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 by, for example, a communication network, or they 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 measuring unit 20 is provided for each of the horses 100. Figure 1 shows an example where there are two horses 100, but is not limited to this. Each horse 100 is ridden by one rider. Each rider uses one whip 110 which has a displacement measuring unit 10. Hereinafter, the two horses 100 will be referred to as the first horse 101 and the second horse 102, the whip 110 used by the rider of the first horse 101 will be referred to as the first whip 111, and the whip 110 used by the rider of the second horse 102 will be referred to as the 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 and 32 consist of a communication circuit or communication module for sending and receiving data with the communication device 3. The communication unit 31 is provided, for example, on the grip of the whip 110 or on the part of the shaft adjacent to the grip. Hereinafter, the communication unit 31 capable of outputting the amount of displacement 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 amount of displacement 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 comprises a first communication unit 311 and a second communication unit 312. The communication unit 32 is attached, for example, to the saddle or saddlecloth 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 rider, a tip provided with shock-absorbing material, and a shaft connecting the grip and the tip.

[0027] The displacement measuring unit 10 is attached to the whip 110 used by the rider and is configured to measure the amount of displacement of the attached whip 110. The displacement measuring unit 10 consists of, for example, 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 to detect, for example, at least one of the 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 measuring unit 20 includes, for example, a position measuring sensor such as a GPS sensor, and is configured to measure the position of the horse 100 ridden by the jockey when the displacement of the whip 110 is measured by the displacement measuring unit 10. The position measuring unit 20 is attached, for example, to the saddle or saddlecloth 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, MPU, GPU, DSP, FPGA, ASIC, or a combination thereof. The storage unit 202 includes, for example, a non-temporary computer-readable storage medium consisting of an internal storage medium or an external storage medium. The internal storage medium includes non-volatile memory, etc. The external storage medium includes a hard disk drive (HDD), solid-state drive (SSD), or optical disc drive, etc.

[0030] The acquisition unit 30 is configured to acquire, via the communication device 3, the amount of displacement 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 determine, based on the acquired displacement of the whip 110, whether or not a "whipping action" was performed, which is the action of the rider swinging the whip 110 so that it hits the horse 100 (in other words, whether or not the whip was used, or whether or not the whip was applied). In this embodiment, the determination unit 40 calculates the position of the horse 100 when it is determined that a "whipping action" was performed, based on the position of the horse 100 measured by the position measuring unit 20.

[0032] For example, suppose the determination unit 40 is configured to determine "whipping action," "practice swing action," and "no action" from the acquired displacement amount of the whip 110. "Practice swing action" refers to the action of the rider swinging the whip 110 so as not to hit the horse 100 (for example, a show whip). "No action" refers to the state in which the rider does not swing the whip 110. The determination unit 40 determines "whipping action," "practice swing action," and "no action" as follows from the difference data D(i) = A(i+1) - A(i) (D(last) = 0, A(i) = raw data of the acquired displacement amount of the whip 110, i = zero and natural numbers) calculated from the acquired displacement amount of the whip 110. Figure 2 shows an example of raw data A and difference data D when "whipping action" is performed. Figures 3 and 4 show an example of raw data A and difference data D when "practice swing action" is performed. Figure 5 shows an example of raw data A and differential data D when multiple "whipping motions" and multiple "swinging motions" are performed. If the absolute value of D(i) is greater than the first threshold th_h (|D(i)|>th_h), the determination unit 40 determines that a "whiplash action" has been performed. If the absolute value of D(i) is less than or equal to the first threshold th_h, and A(i) is greater than the absolute value of the second threshold th_s (|D(i)| ≤ th_h, and |A(i)| > th_s), the determination unit 40 determines that a "practice swing" has been performed. If the absolute value of D(i) is less than or equal to the first threshold th_h, and A(i) is less than or equal to the absolute value of the second threshold th_s (|D(i)|≦th_h, and |A(i)|≦th_s), the determination unit 40 determines that neither the "whipping motion" nor the "swinging motion" is performed (i.e., there is "no motion").

[0033] The determination unit 40 may be configured to determine whether a "practice swing" has been performed based on multiple determinations. For example, if the determination unit 40 first determines that a "practice swing" has been performed, it determines whether the initial determination regarding the "practice swing" is correct or not. Whether the initial determination regarding the "practice swing" is correct or not is determined, for example, by performing the same determination again. In this case, for example, the amount of displacement of the whip 110 obtained after the initial determination regarding the "practice swing" has been performed may be considered, or the results of determinations prior to the initial determination regarding the "practice swing" may be considered. If the initial determination regarding the "practice swing" is determined to be correct, the determination unit 40 determines that a "practice swing" has been performed. On the other hand, if the initial determination regarding the "practice swing" is not determined to be correct, the determination unit 40 changes the determination based on the result of the subsequent determination regarding the "practice swing".

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

[0035] When the determination unit 40 determines that a "whipping action" has been performed, whipping information, including the number of times a "whipping action" was determined to have been performed during the race and the position of the horse 100 at the time the "whipping action" was determined to have 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 Figure 7. Figure 7 shows the display screen 401 of the display device 4. One area of ​​the display screen 401 (for example, the left area in Figure 6) displays the course 402 of the racetrack where the race is being held. The other area of ​​the display screen 401 (for example, the right area in Figure 6) displays one of the horses 100 participating in the race. Along with the course 402, the trajectory 403 of the horse 100 displayed in the other area of ​​the display screen 401 and the position 404 where the "whipping action" was determined to have been performed are displayed in one area of ​​the display screen 401. In the other corner 405 of the display screen 401, the number of times (for example, 6 times) in which a "whiplash motion" was determined to have occurred during the race is displayed.

[0036] The communication device 3 consists of a communication circuit or communication module for sending and receiving data. In this embodiment, the communication device 3 is located at the camera that takes race patrol video and is connected to the judgment device 2, the display device 4, and the respective communication units 31 and 32 by wired or wireless communication.

[0037] The display device 4 is configured to display the position of the horse 100 when the jockey performs a whipping motion. 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 jockeys, etc.

[0038] Referring to Figure 8, an example of the measurement process performed when measuring whiplash motion in the measurement system 1 will be described. The measurement process shown in Figure 8 is performed, for example, by the processor 201 executing a predetermined program stored in the storage unit 202.

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

[0040] Once the measured displacement of the whip 110 and the position of the horse 100 are obtained, the determination unit 40 determines whether or not a whipping motion was performed (step S2).

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

[0042] After step S4, or if it is determined that a "whiplash action" has not occurred (step S2=NO), the measurement system 1 determines whether the termination conditions for ending the measurement process have been met (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 obtained. The termination condition includes, for example, receiving a signal indicating the end of the race, or receiving a command from the user to terminate the process.

[0044] Measurement system 1 can achieve the following effects:

[0045] The measurement system 1 includes a displacement measuring unit 10 capable of measuring the displacement of a whip 110 used by a jockey, and a position measuring unit 20 capable of measuring the position of the horse 100 ridden by the jockey when the displacement of the whip 110 is measured by the displacement measuring unit 10. This configuration makes it 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 motion has been performed based on the measured displacement of the whip 110. This configuration allows for more accurate measurement of the use of the whip 110.

[0047] The determination unit 40 is configured to determine whether a whipping motion, a practice swing motion, or no motion is occurring based on the displacement of the whip 110. This configuration allows for more accurate measurement of the use of the whip 110.

[0048] The measurement system 1 includes a display device 4 capable of notifying that a whipping motion has occurred. This configuration provides race spectators with a better viewing experience.

[0049] The display device 4 is configured to notify the number of whip strikes performed during a race. This configuration provides spectators with a better viewing experience.

[0050] The display device 4 is configured to display the position of the horse 100 when the whipping action is performed. This configuration provides spectators with a better viewing experience.

[0051] The measurement system 1 comprises a first communication unit 311 capable of outputting the amount of displacement 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 amount of displacement of the whip 110 measured by the displacement measuring unit 10 of the second whip 112, and a communication device 3 connected wirelessly 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. With this configuration, the use of the whip 110 can be measured more accurately, and the measurement system 1 capable of measuring the position of the horse 100 when the whip 110 is used can be realized more reliably.

[0052] The communication device 3 is located at the camera that films the race patrol video. This configuration allows the distance between the communication device 3 and the first communication unit 311 and the second communication unit 312 to be shortened. 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 range, such as Bluetooth.

[0053] Measurement system 1 can be configured as follows:

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

[0055] The determination unit 40 can employ any configuration capable of determining whipping, swinging, and no movement. For example, the determination unit 40 may be configured to determine whipping, swinging, and no movement using a trained model created by machine learning the relationship between the measured displacement of the whip 110 and each of the whipping, swinging, and no movement. This makes it possible to measure the use of the whip 110 more accurately and to realize a measurement system 1 that can measure the position of the horse 100 when the whip 110 is used more reliably.

[0056] The determination device 2, the communication device 3, and the display device 4 may be configured as separate devices connected by, for example, a communication network, or they 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.

[0057] The communication device 3 may be configured to output information regarding the whiplash motion to external devices other than the judgment device 2, the display device 4, and the communication units 31 and 32. These external devices include, for example, PCs such as servers, and mobile terminals such as smartphones and tablets. This allows for a better viewing experience for race spectators.

[0058] The notification unit is not limited to a display device 4 capable of providing visual notification. The notification unit may also consist of other devices capable of notifying whipping motions using other senses, including sight, hearing, and touch.
