A speed detection unit that detects the speed of the dart thrown by the player toward the dart target using the speed data received from the speed sensor; and a display unit that displays the dart speed detected by the speed detection unit. [Effect of the invention]

According to the present invention, a dart game device capable of displaying a dart speed, a dart speed display method, and a program can be provided.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol has the same or the same structure.

<Overall Structure> FIG. 1 is an external perspective view of a dart game device according to an embodiment. As shown in FIG. 1, the dart game device 10 is formed in a rectangular parallelepiped shape, for example. The dart game device 10 provides a player with a dart game in which three darts are continuously thrown by one player in one round. The dart may be a soft dart or a hard dart, and is not particularly limited.

The dart game device 10 includes a dart target 12 and a display device 14. The dart target 12 is disposed at an approximate line of sight position of a player in front of the dart game device 10 in a standing posture. The display device 14 displays a still image or a moving image.

A coin insertion slot, a mode selection switch, and the like are provided on the front of the dart game device 10. The player puts the cost into the coin slot, presses the mode selection switch, selects the game mode, and plays a dart game. In this dart game, the player stands at a specific position in front of the dart game device 10, aims at a specific target of the dart target 12 and throws a dart. The end of the dart reaches the dart target 12 before reaching the dart target 12, and the coordinate position of the dart inserted is detected, and the score is displayed on the display device 14 according to the position of the dart.

FIG. 2 is a front view of the dart target 12. The speed sensor 16 is installed at the upper left of the dart target 12 to measure the speed of surrounding objects, and outputs speed data indicating the measured speed of the object. Moreover, the installation position of the speed sensor 16 is not limited to the position shown in FIG. 2. It can be installed at any position as long as the dart speed can be measured.

The disk surface 18 is divided into a plurality of segments with different scores. On the back of the disk surface 18, a segment sensor is installed which detects which of the plurality of segments is pressed. The segment sensor is composed of a switch group provided for each segment. By pressing the switch corresponding to the segment with the force applied when the dart is used to penetrate the segment, a specific dart is inserted into the segment. Section.

An impact sensor for detecting an impact applied to the dart target 12 is mounted on the back of the dart target 12. The impact sensor is used to detect, for example, which position on the entire dart target 12 during dart shooting. In the segment sensor, only a dart hit the disk 18 can be detected by the dart, but if it is an impact sensor, even when the dart shot deviates from the position of the disk 18, the Able to detect being hit by a dart.

In addition, the dart game device 10 may also be provided with a position detection sensor (not necessarily required, and the same will be described in the following description). The position detection sensor includes a plurality of light sources 24A, which are mounted on the dart target. 12; a plurality of light sensors 24B that detect the light intensity of the light emitted from the light source 24A; and a processing device that calculates the position of the disk surface 18 that is penetrated by the dart based on the light intensity. By having a position detection sensor, the dart game device 10 can determine the position where the dart penetrates into the disk surface 18 with a more detailed accuracy than the segment unit.

<Hardware Configuration> FIG. 3 is a diagram showing an example of a hardware configuration of the dart game device 10. The dart game device 10 includes a display device 14, a speed sensor 16, an impact sensor 20, a segment sensor 22, a light source 24A, a light sensor 24B, an operation device 26, and a control device 30. The control device 30 includes a CPU (Central Processing Unit) 32 and a memory 34 that control the entire system.

When the power of the dart game device 10 is turned on, the CPU 32 reads the game program according to the startup program stored in the memory 34 and outputs the game screen to the display device 14. In addition, a game mode desired by the player is made by a coin input signal from the operation device 26, an input signal from a selection switch, a game start switch, and the like.

<Functional Block Configuration> FIG. 4 is a diagram showing an example of a functional block configuration of the dart game device 10. The dart game device 10 includes a game execution unit 100, a speed detection unit 102, a display unit 104, and a violation detection unit 106. The game execution unit 100, the speed detection unit 102, the display unit 104, and the violation detection unit 106 can be implemented by causing the CPU 32 to execute processing of a program stored in the memory 34. The program can be stored on a recording medium. The recording medium storing the program may be a non-transitory recording medium that can be read by a computer. The non-transitory recording medium is not particularly limited, and may be, for example, a USB (Universal Serial Bus) memory and a CD-ROM (Compact Disc-Read Only Memory).

The game execution unit 100 has a function of performing various processes for executing a dart game. The various processes include, for example, performing a game mode selected by the player, determining that the dart is hitting the dart target 12, determining the position where the dart penetrates the disk surface 18, calculating a score, and displaying an animation for playing the dart game.

In addition, the game execution unit 100 determines the time when the impact is detected by the impact sensor 20 as the time when the dart hits the dart target 12. In addition, the game execution unit 100 may detect the point when the segment sensor 22 detects that any of the plurality of segments included in the dart target 12 is pressed, regardless of whether the impact sensor 20 detects an impact, or The time point when the position detection sensor receives the notification that the dart is pierced into the disk surface 18 is determined as the time when the dart hits the dart target 12. When the game execution unit 100 determines that the dart hit the dart target 12, the game execution unit 100 notifies the speed detection unit 102 that the dart has been hit the dart target 12.

The speed detection unit 102 has a function of detecting the speed of the dart thrown by the player toward the dart target 12 using speed data indicating the speed of the object output from the speed sensor 16. Here, the speed sensor 16 provided in the dart game device 10 may be a sensor that discretely outputs speed data indicating the speed of an object detected by the speed sensor 16. In this case, the speed detection unit 102 may also perform a period from the time point when the game execution unit 100 determines that the dart hits the dart target 12 to a time point earlier than that time by a specific time (hereinafter referred to as the “specific determination”). Period ii) The speed data received from the speed sensor 16 is detected as the dart speed.

The display unit 104 has a function of displaying the dart speed detected by the speed detection unit 102 on the display device 14.

The violation detection unit 106 has a function of determining whether or not a player has committed a violation. Specifically, when the game execution unit 100 determines that the dart has penetrated the disk surface 18 and the speed detection unit 102 has detected the speed of the dart, the violation detection unit 106 determines that the player has not performed a violation. When the game execution unit 100 determines that the dart has penetrated the disk surface 18 and the speed detection unit 102 has not detected the speed of the dart, the violation detection unit 106 determines that the player may have committed a violation. The illegal behavior of the player is due to the player pressing the zone and other operations, although the dart is not actually thrown, but it seems to have thrown the dart, thus causing the dart game device 10 to misjudge. It may be set that the game execution unit 100 does not count the score when the violation detection unit 106 determines that the player may have committed a violation. In addition, when the violation detection unit 106 determines that the number of times that a player may have committed a violation exceeds a predetermined number of times set in advance, the game execution unit 100 determines that the player has performed a violation without counting the score.

<Processing Procedure> (Regarding Speed Detection of Dart) Next, a specific processing procedure performed by the dart game device 10 will be described. The speed sensor 16 in this embodiment is, for example, a Doppler sensor, and is mounted on the dart target 12 so as to emit microwaves to the space between the player and the dart game device 10. The speed sensor 16 detects the speed of the object by using the difference between the frequency of the emitted microwave and the frequency of the microwave reflected by the moving object.

FIG. 5 is a diagram for explaining a processing sequence for detecting a dart speed. As shown in FIG. 5, the speed sensor 16 discretely outputs speed data indicating the speed of an object. The vertical direction in FIG. 5 indicates the speed (km / h), and the horizontal direction indicates the time (t). P1 to P6 in FIG. 5 are arranged in order of the time when the speed detection unit 102 receives the speed data output from the speed sensor 16.

Here, since the speed sensor 16 cannot determine whether the moving object is a dart, the speed data output from the speed sensor 16 includes the speed of the dart and the speed detected based on the movement of the player's wrist. Data, or speed data detected by a microwave reflected by a person walking around the dart game device 10.

Therefore, in order to appropriately select the speed data corresponding to the dart speed from the speed data received from the speed sensor 16, the speed detection unit 102 may also determine the following speed data as the speed data corresponding to the dart speed, that is, Among the one or more speed data received from the speed sensor 16 within a specific determination period, the time point closest to the time when it was determined that the dart hit the dart target 12 was received from the speed sensor 16 Speed data.

Here, the specific determination period refers to a time (for example, 1 second or 0.5) from the point in time when the game execution unit 100 determines that the dart hits the dart target 12 (T1 in FIG. 5) to the point forward from that point. Seconds, etc.) between the time points (T2 in FIG. 5). Therefore, the speed detection unit 102 determines the measurement data measured when the dart is about to hit the dart target 12 as the speed data corresponding to the dart speed, so that the speed detected by the player's movement of the wrist by mistake can be suppressed. Speed data such as data that has nothing to do with dart speed is determined as speed data corresponding to the dart speed, so that the dart speed can be detected with higher accuracy.

In addition, the speed sensor 16 may determine the speed data having the fastest speed in a specific determination period as the speed data corresponding to the dart speed. In the store where the dart game device 10 is placed, it is generally considered that there are no objects moving faster than the flying speed of the dart, so it is possible to suppress the erroneous determination of speed data corresponding to objects other than the dart as throwing. Speed data corresponding to dart speed, so that dart speed can be detected with higher accuracy.

Here, it is assumed that the speed data output from the speed sensor 16 does not reach the speed detection unit 102 within a specific determination period due to some factors, and the speed detection unit 102 cannot detect the dart speed. In order to cope with this situation, when the speed detection unit 102 does not exist in the speed data received from the speed sensor 16 within a specific determination period, it may be after the time when it is determined that the dart hits the dart target 12 The speed data received from the speed sensor 16 is determined to be speed data corresponding to the speed of the dart. More specifically, when the speed detection unit 102 does not exist in the speed data received from the speed sensor 16 within a specific determination period, the speed detection unit 102 may The speed data received from the speed sensor 16 during the period from T1) in FIG. 5 to a point in time (T3 in FIG. 5) is determined to be speed data corresponding to the dart speed. Even in the case where the speed data output from the speed sensor 16 is not delivered to the speed detection section 102 due to some delay, the speed detection section 102 can detect the dart speed.

(Correction about dart speed) The speed sensor 16 detects the dart speed using the Doppler effect. Here, when using the Doppler effect to detect the speed, if the microwave transmission direction and the moving direction of the detection target object are not on the same axis, the object speed will be detected as low, thereby causing a measurement error.

FIG. 6 is a graph showing an angle difference between a microwave emission direction and a dart moving direction. A1 indicates the position where the player throws the dart, and B1 and B2 indicate the position where the dart penetrates the disk surface 18. Track O1 represents an example of a player throwing a dart from the position of A1 to pierce the track of B1, and track O2 represents an example of a player throwing a dart from the position of A1 to pierce the track of B2. In addition, L1 is an example of an estimated position where the microwave emitted from the speed sensor 16 collides with a dart and is reflected. When the dart flies along the orbit O1, set the angle difference between the microwave traveling direction and the dart moving direction as θ ₁ , and when the dart flies along the orbit O2, set the microwave travel direction and the dart moving direction The difference is set to θ ₂ . In the case of FIG. 6, since θ ₁ <θ ₂ , the measurement error of the dart throwing speed of the former when the dart flying along the orbit O2 is larger than the case of the dart flying along the orbit O1.

Here, the dart track from the time when the dart is thrown to the time when the dart penetrates into the disk surface 18 will be variously changed according to the position where the player throws the dart, the speed of the dart, and the position where the dart penetrates the disk 18. However, if the position where the player throws the dart is set to be fixed, the dart track can be estimated based on the speed of the dart and the position where the dart penetrates the disk surface 18. The angle formed by the direction of the microwave emission and the direction of the dart movement of the detection object can be estimated by setting the position of the microwave reflection on the dart track to be fixed in advance.

Therefore, in this embodiment, in order to simplify the process of correcting the speed of dart throwing, the position where the player throws the dart throw (A1 in FIG. 6) and the position where the microwave collides with the dart throw (L1 in FIG. 6) can be estimated ) Is set to fixed. In this state, the speed detection unit 102 can also calculate based on the speed data determined as the speed data corresponding to the dart speed among the speed data received from the speed sensor 16 and the position where the dart penetrates the disk surface 18 The angle difference between the direction of travel of the microwave and the direction of dart throwing is used to correct the value of the speed data using the calculated angle difference, thereby detecting the corrected dart throwing speed. Furthermore, when the position of the dart piercing into the disk surface 18 is detected by the segment sensor 22, the speed detecting unit 102 may also regard the position of the dart piercing into the disk surface 18 as the center of the segment. In addition, when the position where the dart penetrates into the disk surface 18 is detected by the position detection sensor, the speed detection unit 102 may set the position detected by the position detection sensor itself as the position where the dart penetrates into the disk surface 18. .

As another method, the dart speed, the position where the dart penetrates into the disk surface 18, and the amount of change in the dart speed caused by the angle difference between the microwave traveling direction and the dart moving direction may be related. The table (speed correction table) is stored in the memory 34 and the like in advance. In addition, the speed detection unit 102 may search the table by using the speed data received from the speed sensor 16 and the position where the dart penetrates into the disk surface 18 as a key, thereby obtaining the variation amount of the dart speed, and using the The obtained change amount is multiplied by the speed data obtained from the speed sensor 16 to detect the dart speed. In the table, the position of the dart piercing into the disk surface 18 is in the disk surface 18, which can be divided by the unit of the section, or by a unit more detailed than the section.

(Modification) In this embodiment, instead of the Doppler sensor, a speed sensor using a stereo camera mounted on the dart target 12 may be used as the speed sensor 16. The speed sensor using a stereo camera, for example, uses two cameras to capture the dart thrown towards the dart target 12 to measure the distance between the dart target 12 and the dart thrower, and the movement of the dart thrower obtained from multiple measurement results. Distance and movement time, calculate the dart speed.

The embodiments described above are intended to make the present invention easier to understand, and are not intended to limit and interpret the present invention. Each element provided in the embodiment, its arrangement, materials, conditions, shape, and dimensions are not limited to those exemplified, and may be appropriately changed. In addition, the components shown in the different embodiments may be partially exchanged or combined with each other.

Moreover, in this embodiment, the so-called ｢部｣ does not only refer to the physical mechanism, but also includes the case where the functions of the ｢部｣ are realized by software. In addition, the functions of one cymbal ridge or device can be realized by two or more physical mechanisms or devices, and the functions of two or more cymbal ridges or devices can be realized by one physical mechanism or device.
