Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, what attached the same code | symbol in each figure has the same or same structure.

<Overall configuration>
FIG. 1 is an external perspective view of the dart game device according to the embodiment. As shown in FIG. 1, the dart game device 10 is formed in, for example, a vertical rectangular shape. The dart game device 10 provides players with a dart game in which one player continuously throws three darts, for example, in one round or the like. Darts are not particularly limited, such as soft darts and hard darts.

The dart game device 10 includes a dart board 12 and a display device 14. The dart board 12 is disposed in the front of the dart game device 10, at a position where the player stands in a substantially line-of-sight position in a standing posture. The display device 14 displays a still image or a moving image.

Further, on the front of the dart game device 10, a coin insertion slot, a mode selection switch, and the like are provided. The player puts a fee into the coin insertion slot, presses the mode selection switch to select the game mode, and plays the dart game. In this dart game, the player stands at a predetermined position in front of the dart game device 10, and throws a dart aiming at a predetermined target of the dart board 12. The dart reached to the dart board 12 is a hard dart, when the tip is stuck to the dart board 12, if it is a soft dart, the tip is made of resin and the dart board 12 target 18 is a dart Since a plurality of holes (not shown) are formed so that the ball is stuck and engaged, when the dart is engaged with the holes (hereinafter, these are collectively referred to as "dart stuck in dart board, etc." The coordinate position of the dart such as stabbed is detected, and the score is displayed on the display device 14 according to the stabbed position.

FIG. 2 is a front view of the dart board 12. The velocity sensor 16 is attached to the upper left of the dart board 12 to measure the velocity of the surrounding object and output velocity data indicating the measured velocity of the object. In addition, the attachment position of the speed sensor 16 is not limited to the place of FIG. It may be attached at any position as long as the dart speed can be measured.

The target 18 is divided into a plurality of segments having different scores, and a displacement sensor 22 (segment sensor) for detecting which of the plurality of segments is pressed is attached to the back of the target 18 .

An impact sensor 20 is attached to the dart board 12 for detecting an impact applied to the dart board 12. For example, as shown in FIG. 2, the impact sensors 20 are attached to four places at approximately the center, upper and lower sides, and left and right of the dart board 12, but the impact sensors 20 are not limited to the places and the number.

As the position detection sensor 24, a plurality of light sources 24A attached around the dart board 12 and a plurality of light sensors 24B for detecting the light intensity of light emitted from the light sources are attached. For example, as shown in FIG. 2, the light sources 24A and the light sensors 24B are attached to approximately the upper, lower, upper and lower four corners of the dart board 12, but the present invention is not limited to this location and number.

<Hardware configuration>
FIG. 3 is a view showing an example of the hardware configuration of the dart game device 10. As shown in FIG. The dart game device 10 includes a display device 14, a speed sensor 16, an impact sensor 20, an intention detection sensor (a displacement sensor 22, a position detection sensor 24), an operation device 26, a target camera 27, a player camera 28, an input / output interface 29 and A control device 30 is provided. In the dart game device 10, for example, the speed sensor 16, the target camera 27, the player camera 28, or the input / output interface 29 may be appropriately selected and provided. The control device 30 includes a CPU 32 and a memory 34 that control the entire system.

When the dart game device 10 is powered on, the CPU 32 reads the game program according to the boot program stored in the memory 34 and outputs the game screen to the display device 14. Further, the game mode desired by the player is advanced by the coin insertion signal from the operation device 26, the select switch, the input signal from the start switch, and the like.

The velocity sensor 16 is a sensor which is installed on the dart board and outputs velocity data indicating the measured velocity of the object. Also, the velocity sensor 16 may be, for example, a sensor that discretely outputs velocity data indicating the velocity of the object detected by the velocity sensor 16.

The speed sensor 16 is, for example, a Doppler sensor, and may be attached to the dartboard 12 so that microwaves are emitted toward the space between the player and the dart game apparatus 10. The velocity sensor 16 detects the velocity of the object using the difference between the frequency of the emitted microwave and the frequency of the microwave reflected from the moving object.

The impact sensor 20 detects an impact applied to the dart board. The impact sensor 20 is used, for example, to detect that the dart has hit any part of the entire dart board 12. The displacement sensor 22 can not detect that the dart has hit unless the dart has hit the target 18, but with the impact sensor 20, even if the dart has hit a location away from the target 18, , Can detect that the dart hit.

The displacement sensor 22 is a sensor that detects that an object has hit by measuring the rearward displacement of the segment of the target 18 of the dart board. The displacement sensor 22 is, for example, a segment sensor that is provided for each segment and configured by a switch group. The segment sensor identifies a segment such as a dart stuck by pressing a switch corresponding to the segment by a force applied when the dart sticks to a segment or the like. With such a configuration, the displacement sensor 22 can detect which of the plurality of segments has been pressed. By providing the displacement sensor 22, the dart game device 10 can easily specify the position of a dart or the like in segment units.

The position detection sensor 24 detects that an object has hit by measuring the light intensity around the dart board. The position detection sensor 24 may be configured of a plurality of light sources 24A and a plurality of light sensors 24B that detect the light intensity of the light emitted from the light sources. The dart game device 10 can determine the position of the dart stuck in the target 18 or the like by providing the position detection sensor 24 in more detail than in the segment unit.

Specifically, when the dart strikes the target 18, the position detection sensor 24 changes the brightness of light toward the light sensor 24B by shielding the light from the light source 24A by the dart, and at least two light sensors 24B Detects the light and dark of the light, these detection signals are sent to the control device 30, and the CPU 32 controls the light and dark (“peak” or “dart”) based on the output of the two light sensors 24B. "Shadow" may be specified, the direction of the dart shadow may be specified, and the position where the dart is pierced may be calculated using a triangulation method.

The displacement sensor 22 and the position detection sensor 24 are both sensors for detecting that an object has hit a segment of the dart board. The displacement sensor 22 and the position detection sensor 24 are generically referred to as the relevant detection sensor. The relevant detection sensor may be, for example, the displacement sensor 22, the position detection sensor 24, or both.

The target camera 27 is a camera for shooting a dart board target. The target camera 27 is installed to be able to shoot an image in which a dart hits a target. The target camera 27 outputs the captured still image or moving image to the image analysis unit 108.

The player camera 28 is a camera for photographing at least a part of the player. The player camera 28 is installed so as to be able to shoot an image in which a player throws a dart. The player camera 28 outputs the captured still image or moving image to the image analysis unit 108.

The input / output interface 29 has a function of mediating exchange of information with an external device. The external device is, for example, an input device such as a keyboard or a mouse, an output device for presenting information to the user, or a network such as the Internet. The dart game device 10 can communicate with various external devices via the input / output interface 29.

<Function block configuration>
FIG. 4 is a diagram showing an example of a functional block configuration of the dart game device 10. As shown in FIG. The dart game device 10 includes a game execution unit 100, a speed detection unit 102, an output unit 104, a fraud determination unit 106, and an image analysis unit 108. The dart game device 10 may be appropriately selected and provided to include the speed detection unit 102 and the image analysis unit 108.

The game execution unit 100, the speed detection unit 102, the output unit 104, the fraud determination unit 106, and the image analysis unit 108 can be realized by processing that a program stored in the memory 34 causes the CPU 32 to execute. . Also, the program can be stored in a recording medium. The recording medium storing the program may be a non-temporary recording medium. The non-transitory recording medium is not particularly limited, but may be, for example, a recording medium such as a USB memory and a CD-ROM.

The game execution unit 100 has a function of performing various processes for executing the dart game. The various processes include, for example, the progress of the game mode selected by the player, the determination that the dart has hit the dart board 12, the determination of the position of the dart being stuck to the target 18, the calculation of the score, the dart game It is an animation display etc. for producing.

The game execution unit 100 detects when the displacement sensor 22 detects the backward displacement of the target on the dart board 12 (for example, the timing when it detects that any one of a plurality of segments included in the target is pressed). Alternatively, it is determined that the timing at which the dart has hit the dart board 12 is determined as the timing at which the position detection sensor 24 notifies that the dart has pierced the target 18 or the like. In addition, the game execution unit 100 may determine, for example, that the timing at which the impact sensor 20 detects an impact is the timing at which the dart hits the dart board 12. When it is determined that the dart has hit the dart board 12, the game execution unit 100 notifies the speed detection unit 102 that it has been determined that the dart has hit the dart board 12.

The velocity detection unit 102 has a function of detecting the velocity of the dart thrown by the player toward the dartboard 12 using velocity data output from the velocity sensor 16 and indicating the velocity of the received object. In addition, the speed detection unit 102 is a period from the timing when the game execution unit 100 determines that the dart has hit the dartboard 12 to the timing before the predetermined timing from the timing (hereinafter referred to as “predetermined determination period” The velocity data received from the velocity sensor 16 may be detected as the velocity of the dart.

In addition to the speed of the dart, the speed sensor 16 detects the speed data detected by the player's arm waving motion, and the speed data output from the speed sensor 16 or the person walking around the dart game apparatus 10 The velocity data etc. which were detected by microwave reflection are also included.

The velocity detection unit 102 selects one or more velocity data received from the velocity sensor 16 within a predetermined determination period in order to appropriately select the velocity data corresponding to the velocity of the dart from the velocity data received from the velocity sensor 16. In the above, the selection may be made based on the timing when it is determined that the dart has hit the dart board 12. For example, the velocity detection unit 102 may determine that the velocity data received from the velocity sensor 16 at the timing closest to the determined timing is the velocity data corresponding to the velocity of the dart.

The predetermined determination period is a period from the timing when the game execution unit 100 determines that the dart has hit the dart board 12 to the timing before a predetermined time (for example, one second, 0.5 seconds, etc.) from the timing. It is. As a result, the speed detection unit 102 determines that the measurement data measured immediately before the dart hits the dart board 12 is the speed data corresponding to the speed of the dart, so that the player shakes his arm. It is possible to prevent that the speed data unrelated to the speed of the dart, such as the detected speed data, is erroneously judged as the speed data corresponding to the speed of the dart, and the dart speed with higher accuracy Can be detected.

The output unit 104 has a function of outputting the determination result of the game execution unit 100 or the fraud determination unit 106. The output unit 104 may output, for example, the velocity of the dart detected by the velocity detection unit 102 or the result of analysis by the image analysis unit 108, as well as the result of the determination. Here, "output" includes all output modes such as outputting to each functional unit, outputting to the input / output interface 29, outputting to the memory 34, outputting (displaying) to the display device 14, etc. .

The output unit 104 may output, for example, the result of the fraud determination by the fraud determination unit 106 described later. Specifically, the output unit 104 is (1) a result of throwing by the game execution unit 100 determined by the fraud determination unit 106 (for example, determination that a dart has hit the dart board 12, a dart is stuck to the target 18, etc. The result of the judgment of the position, the calculation of the score, etc. Output the fraud detection alert showing the warning that the fraud is detected, (2) same as the following, output the (3) throwing result Do not reflect it either, and re-do the corresponding throwing, (4) as a result of the throwing as a result that it is output as "OUT" indicating that the darts did not hit the target 18 and did not score. At least one determination result may be output.

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

The fraud determination unit 106 has a function of determining whether there is a possibility that the player has made a fraudulent act. In other words, the fraud determination unit 106 has a function of determining whether the player has correctly thrown a dart. The cheating by the game player means that the game player does not actually throw a dart, for example, by pushing a finger to press the segment or throwing an object other than a dart such as a brow or the like. It is an action that causes the dart game device 10 to misjudge as if throwing a dart in spite of that. In addition, the injustice may include an act (hereinafter referred to as “near throw”) in which the dart actually throws but the player does not throw from the correct predetermined position (slow line).

For example, the fraud determination unit 106 determines whether or not the impact sensor 20 is operating normally, and even if it is determined that the impact sensor 20 does not operate normally, the determination as to whether the first condition is satisfied is omitted. Good. For example, if the impact value is not output from the impact sensor 20 within the normality determination threshold time, or the impact value output from the impact sensor 20 is a default value (for example, “0 (zero)”) It may be determined that the sensor 20 may not operate properly. The normality determination threshold time refers to a normal time when it is detected that an impact is applied to the dartboard from the timing when the appropriate detection sensor detects that the object has hit the segment. According to such a configuration, when there is a possibility that the impact sensor 20 is not operating properly, the determination process can be omitted.

For example, when the fraud determination unit 106 satisfies the condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined reaction time (hereinafter, referred to as “second condition”), the player performs the fraudulent act It may be determined that there is a possibility. The predetermined reaction time is a value for determining whether or not it is the time of the detection signal due to improperly applying the object including the dart to the time of the detection signal of the determination target. For the predetermined reaction time, a threshold of a normal time when a dart is hit and hit may be set (for example, about 32 msec). According to such a configuration, it is possible to determine at an early stage that cheating (apparently long in time of the detection signal) in which cheating is clearly recognized as finger pressing is made.

For example, when the fraud detection unit 106 detects that the object has hit the segment, the fraud determination unit 106 determines that the shock value detected by the shock sensor 20 is smaller than a predetermined shock value (hereinafter referred to as “ If the first condition is satisfied, it is determined that the player may have misbehaved. The predetermined impact value is a value for determining the impact value due to the fact that the impact value to be determined is an incorrect object including a dart. For the predetermined impact value, a threshold value may be set as to whether or not the impact value is equivalent to the throwing of the dart.

In the case of a fraudulent act of finger pressing or the like, since the segment is directly pressed by the finger or the like, the impact applied to the dart board (particularly, outside the target) is smaller than when the dart is thrown as usual. From this, according to the configuration such as the fraud determination unit 106, the impact value due to finger pressing is less than the impact value due to throwing a dart correctly, and cheating is performed. Can be determined.

For example, when the fraud determination unit 106 satisfies the condition that the velocity of the object detected by the velocity detection unit 102 is not included in the predetermined range (hereinafter, referred to as “third condition”), the player performs fraud It may be determined that there is a possibility that The predetermined range is a value representing the range of normal velocity when the velocity to be determined is thrown from the player's hand toward the dartboard. For example, the upper limit value and / or the lower limit value of the normal speed range may be set in the predetermined range. According to such a configuration, for example, when a dart is thrown using a tool such as a brow or when a dart is thrown by so-called baseball throwing, an impact exceeding a predetermined impact value is applied to the dart board. Although there is a possibility that the condition is not satisfied, even in such a case, by detecting the speed exceeding the predetermined speed and satisfying the third condition, such an action can be detected and determined to be a fraud.

For example, the fraud determination unit 106 determines that the result of the analysis of the image analysis unit 108 indicates that the dart game is not correctly performed according to the predetermined standard within the first predetermined time (hereinafter referred to as “fourth condition”). If satisfied, the player may determine that there is a possibility of misconduct. The first predetermined time is a time during which a player should be thrown to a predetermined area described later when the player correctly throws a dart so that the dart game can be performed correctly. For the first predetermined time, for example, a time such as a few seconds (for example, 1 second or 0.5 second) before the time from the timing when the dart hit the target may be appropriately set.

According to the above configuration, for example, when the player moves from the predetermined position and inserts the dart directly into the target and performs an action such as a hit, it is analyzed that the player does not exist in the predetermined area. It is possible to detect such an act and determine that it is a fraudulent act.

For example, the fraud determination unit 106 determines that the analysis result of the image analysis unit 108 indicates that an object other than the dart is included in the image captured within the second predetermined time (hereinafter referred to as the “fifth condition”. If the player is satisfied with the above, it may be determined that the player may have misbehaved. The second predetermined time is a time during which the dart should be reflected in the image when the player correctly throws the dart. For the second predetermined time, for example, a time of several seconds (for example, 1 second, 0.5 second, etc.) before and after the timing when the dart hit the target may be appropriately set.

According to the above configuration, when an object other than a dart (for example, a player's hand or finger, etc.) is reflected, an action in which the player directly inserts the dart into the target with his hand, or an actual target to the target With a dart inserted by hand to a depth not detected, detect momentarily pressing momentarily from the back of the dart and detect an act etc. such as inserting until the end is detected, and judge it as cheating can do.

For example, if the fraud determination unit 106 determines that there is a possibility that fraudulent activity has occurred, the fraud detection count number may be updated to indicate the number of times the possibility of fraud is detected and determined. Specifically, the fraud determination unit 106 may update the fraud detection count number by incrementing it.

The fraud determination unit 106 determines that the fraud detection determination count number is a predetermined count number for each game or round (for example, the first predetermined number of times for each game, and the second predetermined number for each round) It is judged whether or not (1) the result of throwing by the game execution unit 100 (for example, the judgment that the dart has hit the dart board 12, the judgment of the position such as the dart stuck to the target 18, the calculation of the score etc. It means the result etc. (The same shall apply below) (2) Output a fraud detection alert indicating a warning that fraudulent activity has been detected, (3) Do not reflect anything on the result of casting, and cast the corresponding casting. It may be determined that at least one of (1) to (4) such as (4) outputting as “OUT” indicating that the target 18 did not hit the target 18 as a result of throwing, and (4) as a result of throwing.

For example, if the fraud detection determination count number for each game (hereinafter referred to as “the number of times of fraud detection determination (game)”) is less than the first predetermined number of times, the fraud determination unit 106 sets the above (1). When the number of detection determinations (games) is equal to or greater than the first predetermined number, and the fraud detection determination count number per round (hereinafter, referred to as “the number of fraud detection determinations (round)”) is less than the second predetermined number (2) and (3) above, and the number of fraud detection determinations (game) is equal to or greater than the first predetermined number, and the number of fraud detection determinations per round is equal to or greater than the second predetermined number If it is the case (4), it may be the above (4).

According to the above configuration, it is possible to give a range of the number of times that it is determined to be a fraudulent activity, and to target players who repeatedly perform fraudulent activities, not to score and not to re-do the cast, "OUT" And the like can be output, and the determination result to suppress the fraudulent activity can be output.

If it is determined in the fraud determination unit 106 that there is a possibility that the player has made a fraudulent act, the game execution unit 100 may not count the score. Further, in the game execution unit 100, if the number of times it is determined that there is a possibility that the player has made a fraudulent act by the fraud determination unit 106 exceeds the predetermined number of times set in advance, the player is fraudulent. It may be determined that the action has been taken and the score may not be counted.

The image analysis unit 108 has a function of analyzing a still image or a moving image. The image analysis unit 108 analyzes, for example, an image captured by the player camera, and determines whether the dart game is correctly performed according to a predetermined standard. The predetermined reference is a reference indicating that the dart game is being played correctly. For example, the player who should throw (the turn to throw) is, as usual, near the predetermined position in front of the dart game apparatus 10. Is a standard that indicates that the dart has been thrown. As an example in which the dart game is not played correctly according to the predetermined standard, specifically, the player of the turn to throw in the predetermined area of the photographed image where the player is not present in the predetermined area in the photographed image There is a person other than the person or the like, or a person who is not a player who should be thrown throws a dart. The predetermined area is an area where the presence of a dart can be confirmed when the player throws a dart from near a predetermined position in front of the dart game device 10. In addition, an area that may exist when the player is throwing from a predetermined position may be appropriately set in the predetermined area.

For example, the image analysis unit 108 extracts the feature of the captured image and matches it with a feature pattern indicating that the player is throwing a dart according to a predetermined reference registered in advance in the memory 34 or the like. In the image, it may be analyzed whether the player is throwing a dart according to a predetermined standard. In the analysis, conventional techniques such as person recognition may be used.

For example, the image analysis unit 108 analyzes an image captured by the target camera, and determines whether or not an object other than a dart appears in the image within a second predetermined time. The image analysis unit 108 extracts features of the captured image, for example, and matches the feature pattern representing at least a part of the darts registered in advance in the memory 34 or the like, whereby an object other than the darts is included in the image. You may analyze whether it is reflected. In the analysis, conventional techniques such as image recognition may be used.

<Operation>
5 to 8 are flowcharts showing an example of the operation of the dart game device 10. The operation of the dart game device 10 will be described with reference to FIGS. This operation is repeated for each dart throwing. In addition, the order of the process shown below is an example, Comprising: You may change it suitably.

5 to 6 show an example of an operation of detecting and judging a fraudulent act using the corresponding detection sensor and the impact sensor 20, and the flow chart shown in FIG. 5 and the flow chart shown in FIG. They are connected to each other by the shown connectors.

The dart game device 10 detects that an object has hit the target of the dart board (step S10).

The dart game device 10 determines whether or not the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined reaction time is satisfied (step S11).

When the dart game device 10 does not satisfy the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined reaction time (No in step S11), the dart game device 10 determines whether the impact sensor 20 is operating normally.
