Description

The present invention relates to a number of strokes measurement system for measuring the number of strokes in golf.

A counting system that can more accurately count the number of hits made with a hitting tool has been disclosed (see Patent Document 1). The counting system described in Patent Document 1 uses time and position information to prevent miscounts caused by collisions between the golf club and objects other than the ball, which would otherwise not be counted in the number of strokes.

Japanese Patent Application Publication No. 2016-64101

Counting systems described in the prior art document count the number of balls hit during the play of golf. However, the additional number of at-bats due to a penalty under the rules such as OB is not the actual number of at-bats, so the only way to record it is as a separate number of at-bats. Also, according to the rules of golf, even if there is no collision between the golf club and the ball, such as when you intend to hit and miss, it must be counted as one shot, and an unintentional double hit is counted as two shots. Collisions will be measured, but there are no penalties under current rules. Therefore, it is desirable that the number of strokes other than those added as penalties be counted correctly.

The present invention has been made in view of these circumstances, and its purpose is to provide a technique for accurately counting the number of strokes during play in golf.

In order to solve the above problems, the number of strokes counting system for counting the number of strokes of the present invention includes an acceleration sensor that detects the movement of a golf club and outputs the detected result as swing information, and a biological body that detects the player's biological information. It includes a sensor, and a count determination unit that determines whether or not to count the number of strokes based on the swing information and the biological information, and the count determination unit determines whether or not the swing is started and the ball is hit based on the swing information. If the impact of hitting the ball is detected, it will be counted as one stroke, and if the swing has started and the impact of hitting the ball is not detected, the count determination unit will count it as one stroke based on the change in biological information immediately after the swing. It is characterized by determining whether or not to do so.

According to the present invention, it is possible to accurately count the number of strokes during a game of golf.

FIG. 1 is a block diagram showing the configuration of a number of strokes counting system according to an embodiment of the present invention. FIG. 1 is an external view showing a state in which a number of strokes counting system according to an embodiment of the present invention is implemented. It is a flow diagram showing the operation of counting the number of strokes of the number of strokes counting system according to the embodiment of the present invention. FIG. 2 is a flowchart showing operations related to cumulative number of strokes of the number of strokes measuring system according to the embodiment of the present invention.

In the present invention, the following two techniques are well known. The first is the technology of a swing analysis device attached to a golf club, which uses an acceleration sensor to detect the movement of the club during a swing, the timing of hitting the ball, etc., and visualizes the detection results as information. The visualized information includes the trajectory of the golf club during the swing, as well as indicators such as the speed, time, and angle of the club head and grip. Swing analysis devices are often used for the purpose of analyzing swings at practice ranges and lesson grounds, rather than as devices that are actually used for playing on golf courses. The second technology is a technology that uses biosensors to detect various biological information, and the technology that transmits that information and visualizes it in real time is a function that many current mobile devices have. be.

A number of strokes counting system according to Embodiment 1 of the present invention will be described with reference to FIG. The number of strokes measuring system according to the first embodiment of the present invention includes a number of strokes measuring section 10 and a biological information detecting section 20.

The number of strokes measuring section 10 includes an acceleration sensor 101, a count determination section 102, a communication section 103, a display section 104, and an operation section 105. The acceleration sensor 101 is a detector that detects the movement of the golf club in the swing analysis device described above, but it also detects the movement of the person holding the golf club. The detection of the swing movement by the acceleration sensor 101 and the detection of the impact when the ball is hit are well-known techniques, and detailed explanations thereof will be omitted. The count determination unit 102 determines whether or not to count as one stroke based on information such as “motion” and “impact” detected by the acceleration sensor 101 and biological information transmitted from the biological information detection unit 20, which will be described later. The number of strokes counted during play is accumulated. The display unit 104 displays the accumulated number of strokes and performs necessary display based on the operation of the operation unit 105. The operation unit 105 is a switch for performing operations necessary to turn on/off the power of the at-bat counting system, which is this device, and make various settings. Become. The communication unit 103 is configured to receive biometric information transmitted from a biometric information detection unit 20, which will be described later. The communication unit 103 is a short-range communication means, and is configured to perform communication using, for example, Bluetooth (registered trademark).

FIG. 2 is a diagram showing an example of a state in which the number of strokes measuring section 10 is installed. A in FIG. 2 is a diagram schematically representing a player, and shows an address posture. As for the shape and state of wearing of the number-of-strokes measuring section 10, as shown by X in FIG. 2, it is in the shape of a watch and is worn on the wrist that does not feel like it will interfere with the swing. Further, the number of strokes measuring section 10 includes an acceleration sensor 101 and a communication section 103. Alternatively, as shown in Y in FIG. 2, the glove may be shaped so that it can be attached to the back of the hand with a clip or the like, and the acceleration sensor 101 and the communication unit 103 may be provided inside.

Further, the number of strokes measuring section 10 does not necessarily need to be configured as one piece. For example, FIG. 2B is a diagram schematically showing a golf cart, in which a golf cart 50 and a caddy bag 60 are mounted on the rear thereof, and a golf club 70 is stored in the caddy bag 60. An acceleration sensor (101A, 101B, 101C, . . . ) may be provided for each golf club, and in that case, communication means may be provided between each of the acceleration sensors and the count determination unit 102. The communication means may be wired, but it is preferable to use wireless communication that does not hinder movement.

Regarding the number of strokes measuring section 10, the acceleration sensor 101 must be attached to the player or the club, but the other components, such as the count determination section 102, display section 104, and operation section 105, are attached to the golf cart 50 as the number of strokes measuring section 10A. You may be prepared. In this case, the acceleration sensor 101 and the communication unit 103 need to be integrated.

In recent years, golf carts have been equipped with tablet terminals that have a course layout display function (104A in Figure 2B) and a score (number of strokes) display and input function (104B and 105B in Figure 2B) as part of the golf course management system. It is often The tablet terminal provided in the golf cart 50 may include the number of strokes measuring section 10A including the count determining section 102, the communication section 103, the display section 104, and the operation section 105 according to the present invention. Conventionally, the score input function was manually input after each hole was played, but in the embodiment of the present invention, this score input can be automated by detecting the number of strokes. Note that the "number of at-bats" only refers to the number of balls hit, including penalties under the rules, and the score is information recorded based on the number of at-bats, but in the present invention, it can be interpreted as substantially the same. do.

Return to Figure 1. The biological information detection unit 20 includes a biological sensor 201 that detects biological information, and a communication unit 202 that transmits the detected biological information to the number of strokes measurement unit 10. Note that a plurality of biosensors (201A, 201B, . . . ) that detect different biometric information may be provided. In addition, in the case of the watch type shown previously with Often, biological information detected by the biological sensor 201 may be directly input to the count determination section 102.

The biosensor 201 detects biometric information of the player. In the present invention, the purpose of detecting biometric information is to detect psychological agitation of the player. For example, if a player starts to swing but does not hit the ball, is this a practice swing that he does before actually hitting the ball? It is difficult to judge just from the movement of the body and club. Therefore, the biosensor 200 of the present invention detects biometric information such as the player's heartbeat, blood pressure, body temperature, respiratory rate, brain waves, and electrocardiogram, and measures how the biometric information changes before and after the swing. The number of strokes measuring section 10 determines whether the ball is a missed swing or a practice swing, depending on the amount of change in the measurement result. If it is determined to be a missed swing, it will be counted as one stroke, and if it is determined to be a practice swing, it will not be counted as one stroke.

In the present invention, determination between a missed swing and a practice swing is performed as follows. In the case of the present invention, there is a fixed situation in which a swing is detected but a ball hit is not detected, so in this situation, the biometric information before the swing and the biometric information after the swing are compared, and the biometric information before the swing is compared. A threshold value is set for the degree of change (rate of change) between the value of biometric information and the value of biometric information after swinging.For example, after swinging, increase in blood pressure, increase in heart rate, increase in body temperature, amount of sweat If a change due to an increase in , etc. is observed, and the rate of change of one or more biological information exceeds the threshold,
It is judged as a “miss shot”. On the other hand, in the case of practice swings, the player's psychological state is that they are concentrating on the next hit and are swinging with the intention of not hitting the ball, so it is difficult for a player to swing and detect a ball hit. Even if not, if the biological information does not change before and after the swing, that is, if the rate of change of one or more biological information does not exceed the threshold value before and after the swing, it is determined that the swing is a "practice swing". A case in which the rate of change of one or more biological information exceeds the threshold value may be defined as "psychological agitation," and the rate of change of one or more biological information does not exceed the threshold value. In such cases, it may be defined as "no psychological agitation."

The shape of the biometric information detection section 20 may be any shape as long as it can accurately detect biometric information without causing any problems during golf play. It may be in the shape of a watch like the shape shown for the number of strokes measuring section 10, or the biosensor 201 and the communication section 202 may be mounted on the cap as shown in Z of A in FIG.

The operation of the number of strokes counting system according to the first embodiment of the present invention will be explained using FIG. 3. FIG. 3 is a flowchart for determining whether or not to count the number of strokes.

First, with reference to FIG. 3, the flow of the operation for determining whether or not to count a swing as the number of strokes will be explained. First, the acceleration sensor 101 detects whether the player and the club are stationary (step S101). The stationary state of the player and the club refers to the period from when the player takes the address position with the club held relative to the ball position until the player starts to swing. Although the actions from this state to the start of the swing differ from player to player, a common feature is a state in which the amount of movement or acceleration detected by the acceleration sensor 101 is below a predetermined value. This state is a state in which the detection information of the movement of the body and the club is significantly reduced, that is, there is almost no movement for a predetermined period of time, and in the present invention, this state is regarded as stationary.

In step S101, detection of stationary state is started, and it is determined whether or not the vehicle has been stationary for a predetermined period of time (step S102). Although an initial value is determined for this predetermined time, since the actual rest time varies depending on the player and is not constant, it is desirable that the result of the determination be fed back to the next determination. The explanation will proceed assuming that the device remains stationary for a predetermined period of time in step S102 (step S102: Yes).

If it is detected that the robot has been stationary for a predetermined period of time, the execution of a swing is detected (step S103), and it is detected whether or not the swing has been executed (step S104). The execution of the swing is detected by the acceleration sensor 101. If execution of a swing is not detected in step S104, it is determined whether the stillness is still continuing or has been canceled (step S105). If the stationary state continues, that is, the stationary state has not been canceled (step S105: No), the process returns to step S103 and swing detection continues. When the stationary state is released (step S105: Yes), the flow of measuring the number of strokes ends. As explained above, in the present invention, stationary means "substantially stationary" and means a state in which detected information about the movement of the body and club is significantly reduced. Therefore, "the stillness is released" is when a clear movement is detected, that is, when some kind of movement is performed, which may be a hand, a foot, a neck, or a club.

A case in which a swing is executed after coming to rest will be explained. If execution of a swing is detected in step S104 (step S104: Yes), a state is set in which a ball hit is detected (step S106), and it is detected whether or not the ball has been hit (step S107). Whether or not the player has hit the ball is determined by using the acceleration sensor 101 to detect the impact of the club hitting the ball while swinging the club. If an impact is detected by the acceleration sensor 101 (step S107: Yes), the count determination unit 102 counts as "1 stroke" (step S108), and ends the flow of measuring the number of strokes.

Next, a flow for determining whether a swing is executed but no ball hit is detected, that is, whether it is a practice swing or a missed swing, will be described. If the impact of hitting the ball is not detected (step S107: No), biological information from various biological sensors provided in the biological information detection unit 20 immediately after the swing is extracted (step S109).

Based on the biological information extracted in step S109, it is determined whether the change is a predetermined change. First, a case where the condition is not determined to be a predetermined symptom (step S110: No) will be described. For example, if the rate of change in heart rate, blood pressure, etc. is below a predetermined value immediately after a swing, it can be said that the player is maintaining a calm state. After addressing and coming to rest, you begin your swing, but if you don't hit the ball, but you don't hit it; in other words, if you remain calm immediately after your swing, it is considered a "practice swing," especially if you do not hit the ball. The flow of measuring the number of strokes ends without counting.

If it is determined that the change is a predetermined change (step S110: Yes), symptoms such as a sudden change in heart rate and blood pressure, a sudden rise in body temperature, and increased sweating appear immediately after the swing, and changes in the values of biological information before and after the swing occur. If the rate is above a predetermined threshold, it can be said that the person is clearly agitated. In this case, it is assumed that a predetermined symptom exists, and the process proceeds to step S108. In this state, after addressing and standing still, the player starts swinging with the intention of hitting the ball, but does not hit the ball, that is, it is a "missing swing", and the ball is counted as one hit in step S108, and the flow of measuring the number of hits ends.

The above is an explanation of the operation of counting the number of strokes as one stroke in the stroke count counting system according to the first embodiment of the present invention. Under the current rules, if a player hits the ball twice in one swing, there is no penalty for unintentionally hitting the ball twice. In the present invention, in the case of a double hit, the acceleration sensor 101 detects two hits of the ball during one swing. Furthermore, the acceleration sensor 101 may detect a situation called "scalping" in which the player hits the ground before hitting the ball and then hits the ball, as a symptom of being hit twice by the ball. However, in the present invention, even if the acceleration sensor 101 detects the impact multiple times during one swing, it is counted as one hit, so there is no particular problem.

A configuration for accumulating the number of strokes while playing a course will be explained. Since it is desirable to store information cumulatively for each hole on the course, a configuration is required to detect the number of the hole currently being played. This will be done using location information, but if the number of strokes counting system of the present invention is included as part of the golf course management system that includes the tablet terminal installed in the golf cart as described above, it can be shared. It is efficient with a lot of structure and information. Therefore, the number of strokes measuring system of the present invention includes the number of strokes measuring section 10, a position detection section 106 using GNSS (Global Navigation Satellite System), etc., and a storage section 107 that stores the layout of each hole of the golf course as position information. .

The golf course management system described earlier uses position information detection means for each golf cart to determine which hole is being played, and displays information about the hole being played on the display of the tablet terminal. do. The information displayed on the tablet terminal includes a layout diagram of each hole and a diagram showing pin positions on the green. The range shown in the layout diagram shall be the range of the hole. The number of strokes measurement system assumes that the hole being played is determined based on the position of the golf cart, and if the position of the cart is included in the range indicated by the layout diagram, the hole in the layout diagram is considered to be the hole being played. do. The number of strokes is recorded and reset based on the information that the hole where the cart is located has changed. In detail, the number of strokes is accumulated within the range of the hole currently being played, and when the position of the cart moves out of the range of the hole being played, the number of strokes for the hole that deviated is recorded, and the number of strokes is counted for a new hole. When the range is reached, reset the stroke count.

The operation related to the cumulative number of strokes according to the number of strokes counting system of the present invention will be explained using FIG. 4. In the present invention, the total number of strokes (scores) is recorded on a tablet terminal provided in a golf cart. The position of the golf cart is detected by the position detection unit 106 (step S201). Based on the hole layout information stored in the storage unit 107, it is determined whether movement across holes has been performed (step S202). Moving between holes means, for example, finishing the 8th hole and moving to the 9th hole, but when the position information of the cart 50 is out of the range indicated by the layout diagram of the 8th hole, It may be determined as a movement.

First, if movement between holes has not been performed (No in step S202), since that hole is still being played, the number of strokes count flow (step S204) is performed. The number of strokes count flow is a flow for determining whether or not to count the number of strokes shown in FIG. 3. If the number of strokes is detected in step S204, one stroke is added to the number of strokes (step S205), and the process returns to step S201.

On the other hand, if movement between holes is detected (Yes in step S202), it is determined whether the last played hole is the 9th hole, the 18th hole, or any other hole (step S203). ). In other words, when the hole that was being played up to that point has finished playing and the position information of the cart 50 has moved out of the range of the finished hole, and the finished hole is not the 9th hole or the 18th hole (step S203 (No), the number of strokes for the completed hole is recorded (step S206), and the number of strokes is reset in order to perform a new count for the next hole (step S207). Note that the number of strokes may be reset when it is detected that the position of the cart has entered the range of the hole to be played next. The process then returns to step S201.

If the last hole played is either the 9th hole or the 18th hole (Yes in step S203), the number of strokes for the completed hole is recorded (step S208), and the number of strokes for the completed hole is recorded (step S208), At the end of the process, the number of strokes for each completed hole is totaled and a score is calculated (step S209).

Note that the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the spirit.
