<Overall composition>

FIG. 1 is a perspective view of the appearance of the dart game apparatus according to the embodiment. As shown in FIG. 1, the dart game apparatus 10 is formed in, for example, a vertical rectangular parallelepiped shape. The dart game apparatus 10 provides a dart game in which three darts are continuously thrown by one player in one round, for example. The darts are soft darts, hard darts, or the like, and are not particularly limited.

The dart game device 10 includes a dart board 12 and a display device 14 . The dart board 12 is disposed on the front surface of the dart game apparatus 10 at an approximate line-of-sight position of the player in the standing posture. The display device 14 displays still images or moving images.

In addition, a coin slot, a mode selection switch, and the like are provided on the front surface of the dart game device 10 . The player inserts the game fee into the coin slot, presses the mode selection switch, selects the game mode, and plays the dart game. In this dart game, the player stands at a specific position in front of the dart game device 10 and throws darts at a specific target of the dart board 12 . If the dart reaching the dart board 12 is a hard dart, when the front end pierces the dart board 12, if it is a soft dart, since the front end part is made of resin, and the target 18 of the dart board 12 is formed with a not-shown. The plurality of holes allow the dart to penetrate and engage. Therefore, when the dart is engaged with the hole (hereinafter, these are collectively referred to as "dart piercing into the dart board, etc."), the coordinate position of the dart such as the piercing dart is detected, The score is displayed on the display device 14 according to the position of the puncture or the like.

FIG. 2 is a front view of the dart board 12 . The speed sensor 16 is installed on the upper left of the dart board 12, measures the speed of the surrounding objects, and outputs speed data representing the speed of the measured objects. Furthermore, the installation position of the speed sensor 16 is not limited to the position shown in FIG. 2 . It can be installed in any position, as long as the speed of the dart can be measured.

The target 18 is divided into a plurality of sections with different scores, and a displacement sensor 22 (section sensor) for detecting which section of the plurality of sections is pressed is installed on the back of the target 18 .

The dart board 12 is provided with an impact sensor 20 that detects the impact applied to the dart board 12 . For example, as shown in FIG. 2 , the impact sensors 20 are installed at four locations, above and below, and on the left and right sides of the approximate center of the dart board 12 , but are not limited to these locations and the number.

As the position detection sensor 24, there are installed: a plurality of light sources 24A, which are installed on the periphery of the dart board 12; and a plurality of light sensors 24B, which detect the light intensity of light emitted from the light sources. For example, as shown in FIG. 2 , the light source 24A and the light sensor 24B are installed on the upper and lower sides of the approximate center of the dart board 12 and in the vicinity of the four corners, but are not limited to these positions and numbers.

<Hardware configuration>

FIG. 3 is a diagram showing an example of the hardware configuration of the dart game apparatus 10 . The dart game device 10 includes a display device 14 , a speed sensor 16 , an impact sensor 20 , a hit detection sensor (displacement sensor 22 , position detection sensor 24 ), an operation device 26 , and a target camera 27. Player camera 28, input/output interface 29 and control device 30. Furthermore, 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 provided as appropriate. The control device 30 includes a CPU 32 for controlling the entire system, and a memory 34 .

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 . Furthermore, the game mode desired by the player is performed by the coin insertion signal from the operation device 26, the selection switch, the input signal from the start switch, and the like.

The speed sensor 16 is provided on the dart board, and outputs speed data representing the speed of the measured object. Also, the speed sensor 16 may be, for example, a sensor that discretely outputs speed data representing the speed of the object detected by the speed sensor 16 .

The speed sensor 16 is, for example, a Doppler sensor, and can be installed on the dart board 12 in such a way that microwaves are radiated toward the space between the player and the dart game apparatus 10 . The speed sensor 16 detects the speed 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 the impact applied to the dart board. The impact sensor 20 is used, for example, to detect that a dart hits any part of the entire dart board 12 . The displacement sensor 22 cannot detect the dart hitting as long as the dart does not hit the target 18 , but if it is the impact sensor 20 , even when the dart hits a part far from the target 18 , it can detect the dart hitting .

The displacement sensor 22 is a sensor that detects an object hit by measuring the rearward displacement of the section of the target 18 of the dart board. The displacement sensor 22 is, for example, provided for each partition, and is a partition sensor composed of a switch group. The zone sensor depresses the switch corresponding to the zone by using the force applied when the dart pierces the zone, and the dart pierces the zone, and so on. With this configuration, the displacement sensor 22 can detect which partition is pressed among the plurality of partitions. The dart game apparatus 10 can easily specify a position such as a dart piercing in a divisional unit by including the displacement sensor 22 .

The position detection sensor 24 detects an object hit by measuring the light intensity around the dart board. The position detection sensor 24 may be configured to include a plurality of light sources 24A and a plurality of light sensors 24B that detect the light intensity of light emitted from the light sources. The dart game apparatus 10 is provided with the position detection sensor 24, and can determine the position, such as a dart piercing toward the target 18, in more detail than divisional units.

The position detection sensor 24 specifically, if the dart pierces the target 18, the light from the light source 24A is blocked by the dart, and the light and shade of the light toward the light sensor 24B changes, and at least two light sensors 24B Detect the brightness of the light, and transmit these detection signals to the control device 30, and the brightness ("peak" or "dart shadow") of the light based on the dart can be specified by the CPU 32 according to the outputs of the two light sensors 24B. ), specify the direction of the dart shadow, and use the method of triangulation to calculate the position where the dart penetrates.

Furthermore, any one of the displacement sensor 22 and the position detection sensor 24 is a sensor for detecting that the object hits the partition of the dart board. The displacement sensor 22 and the position detection sensor 24 are collectively referred to as a hit detection sensor. The hit 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 photographing the target of the dart board. The target camera 27 is configured to capture an image of the dart hitting the 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 portion of the player. The player camera 28 is provided so as to capture an image of the player (player) throwing darts. The player camera 28 outputs the captured still image or moving image to the image analysis unit 108 .

The input/output interface 29 has an intermediary function of intermediating the exchange of information with external devices. External devices are input devices such as keyboards and mice, which are used to The output device of the user prompt information, or the network such as the Internet. The dart game device 10 can communicate with various external devices via the input/output interface 29 .

<Function block composition>

FIG. 4 is a diagram showing an example of the functional block configuration of the dart game apparatus 10 . The dart game device 10 includes a game execution unit 100 , a speed detection unit 102 , an output unit 104 , a cheat determination unit 106 , and an image analysis unit 108 . In addition, in the dart game apparatus 10, the speed detection part 102 and the image analysis part 108 may be provided by selecting and providing them appropriately.

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

The game execution unit 100 has a function of performing various processes for executing a dart game. Various processes include, for example, performing the game mode selected by the player, determining that the dart hits the dart board 12, determining the position where the dart pierces the target 18, calculating the score, and displaying animations for demonstrating the dart game.

The game execution unit 100 detects the time sequence when the displacement sensor 22 detects the displacement of the target of the dart board 12 toward the rear (for example, detects the time sequence when any one of the plurality of partitions included in the target is pressed), Or it is determined that the dart hits the dart board from the timing when the position detection sensor 24 informs the dart to penetrate the target 18, etc. 12 timings. In addition, the game execution unit 100 may, for example, determine the timing when the impact sensor 20 detects the impact as the timing when the dart hits the dart board 12 . When it is determined that the dart hits the dart board 12, the game execution part 100 notifies the speed detection part 102 that it is determined that the dart has hit the dart board 12.

The speed detection unit 102 has a function of detecting the speed at which the player throws darts at the dart board 12 using the speed data representing the speed of the object received and output from the speed sensor 16 . In addition, the speed detection unit 102 may determine the period from the timing when the game execution unit 100 determines that the dart hits the dart board 12 to the timing earlier than the timing by a predetermined time (hereinafter referred to as "specific determination period") from The speed data received by the speed sensor 16 is detected as the speed of the dart.

In the speed data output from the speed sensor 16, in addition to the speed of the darts, the speed sensor 16 also includes the speed data detected by the action of the player swinging the arm, and the speed data detected by the dart game device. Speed data, etc. detected by reflected microwaves of people walking around 10.

In order to appropriately select the speed data corresponding to the speed of the dart from the speed data received from the speed sensor 16, the speed detection unit 102 may also receive one speed data from the speed sensor 16 within a specific determination period. Among the above speed data, selection is made based on the timing at which it is determined that the dart hits the dart board 12 . For example, the speed detection unit 102 may also determine the speed data received from the speed sensor 16 at the timing closest to the determined timing as the speed data corresponding to the speed of the dart.

The specific determination period is the period from the time sequence when the game execution unit 100 determines that the dart hits the dart board 12 to the time sequence before the specific time (for example, 1 second, 0.5 second, etc.) before the time sequence. borrow In this way, since the speed detection unit 102 determines the measurement data measured when the dart is about to hit the dart board 12 as the speed data corresponding to the speed of the dart, it is possible to suppress the speed that would be detected by the action of the player swinging his arm. Data, etc., speed data irrelevant to the speed of the dart is incorrectly determined as the speed data corresponding to the speed of the dart, and the speed of the dart can be detected with higher accuracy.

The output unit 104 has a function of outputting the result of the determination made by the game execution unit 100 or the cheat determination unit 106 . The output unit 104 may output, for example, the speed of the dart detected by the speed detection unit 102 or the result of analysis by the image analysis unit 108, in addition to the result of the determination. The "output" referred to here includes: output to each functional unit, output to the input/output interface 29, output to the memory 34, and output (display) to the display device 14, etc.

The output unit 104 may output, for example, the result of cheating determination by the cheating determination unit 106 described later. Specifically, the output unit 104 can output: (1) outputting the throwing result of the game execution unit 100 (for example, the judgment of the dart hitting the dart board 12 , the position where the dart pierces the target 18 , etc.) (2) outputting a cheating detection alarm indicating a warning that the subject of cheating has been detected; (3) no response to the throwing result, and the throwing is performed again; (4) ) as the throwing result to output at least one of the judgment results (1) to (4) of "OUT" indicating that the dart did not hit the target 18 and failed to score.

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 cheating determination unit 106 has the function of determining whether the player has a possibility of cheating can. In other words, the cheating determination unit 106 has a function of determining whether or not the player throws the darts correctly. The so-called cheating behavior by the player is, for example, by the player pressing the finger to press the partition by himself, or throwing an object other than darts such as a dart. 10 Mistakenly judged as having thrown a dart. In addition, the cheating behavior also includes the behavior that the player does not throw the dart from the correct specific position (throw line, throwing line) even though the dart is actually thrown (hereinafter referred to as "throwing over the line").

For example, the cheating determination unit 106 determines whether the impact sensor 20 is operating normally, and when it is determined that the impact sensor 20 is not operating normally, the determination of whether or not the first condition is satisfied may be omitted. The cheating determination unit 106, for example, can determine the shock feeling when the shock sensor 20 does not output the shock value within the normal judgment threshold value time or the output shock value is a preset value (for example, "0 (zero)", etc.). There is a possibility that the detector 20 may not operate normally. The so-called normal judgment threshold value time refers to the normal time from the time sequence when the hit detection sensor detects that the object hits the partition to when the impact is applied to the dart board. According to such a configuration, when there is a possibility that the impact sensor 20 may not operate normally, this determination process can be omitted.

For example, when the time of the detection signal from the displacement sensor 22 satisfies a condition that is longer than a specific reaction time (hereinafter referred to as the "second condition"), the cheating determination unit 106 can determine that the player has a possibility of cheating. . The so-called specific reaction time is the value of the time for determining whether or not the detection signal of the object including the darts is cheated to hit the detection signal. For a specific reaction time, a threshold value (for example, about 32 msec) of the usual time when a dart is thrown and hit can be set. According to such a configuration, cheating that is clearly determined to be a finger press (the time of the detection signal is obviously long) can be determined to be cheating at an early stage.

For example, when the hit detection sensor detects that an object hits the partition, the cheating determination unit 106 satisfies a condition that the shock value of the shock detected by the shock sensor 20 is smaller than a specific shock value (hereinafter referred to as "the first condition"). ”), it is determined that the player has the possibility of cheating. The so-called specific impact value is a value for judging whether or not the impact value of the judgment object is the impact value of the object containing the darts thrown fraudulently. For a specific impact value, it is possible to set whether it is the threshold value of the impact value of throwing darts.

In the cheating act of hitting by pressing the finger, etc., it is used to hit by directly pressing the partition with the finger, etc., so it is applied to the dart board (especially outside the target) compared with the case of throwing darts as usual. ) has a small impact. Therefore, according to the configuration of the cheating determination unit 106, the impact value of the hit by pressing the finger is smaller than the impact value of the hit by throwing the dart correctly, and it can be determined whether or not cheating has been performed.

For example, when the speed of the object detected by the speed detection unit 102 satisfies a condition that is not included in a specific range (hereinafter referred to as "third condition"), the cheating determination unit 106 may determine that the player has a possibility of cheating. The so-called specific range is a value representing a range in which the speed of the judgment object is the normal speed of throwing darts from the player's hand to the dart board. For a specific range, for example, an upper limit value and/or a lower limit value of the normal speed range can be set. With such a configuration, for example, when throwing darts using props such as blow arrows, or when throwing darts by so-called baseball throwing, an impact exceeding a specific impact value is applied to the dart board, and the first condition may not be satisfied. , but in this case, the third condition can also be satisfied by detecting the speed exceeding the specific speed, and such behavior can be detected as cheating.

The cheating determination unit 106 can determine the player, for example, when the result of the analysis by the image analysis unit 108 satisfies the condition that the dart game is not played correctly according to the specified criteria within the first specified time (hereinafter referred to as the "fourth condition"). There is a possibility of cheating. The so-called first specific time is the time when the player who should throw the dart should be located in the specific area described later when the player throws the dart correctly in order to correctly play the dart game. For the first specific time, for example, a time of a few tenths of a second (for example, 1 second or 0.5 second) before the timing when the dart hit the target can be appropriately set.

According to the above configuration, for example, when the player moves from the specific position and directly inserts the dart into the target and throws the dart, it is analyzed that the player is not located in the specific area, such behavior is detected and it can be determined as cheating behavior .

The cheat determination unit 106 can determine the game, for example, when the result of the analysis by the image analysis unit 108 satisfies the condition that an object other than the dart is reflected in the image captured within the second specific time (hereinafter referred to as the "fifth condition"). There is a possibility of cheating. The second specific time is the time when the dart should be reflected in the image when the player throws the dart correctly. For the second specific time, for example, a time period of a few tenths of a second (for example, 1 second or 0.5 seconds, etc.) can be appropriately set from the timing of detecting that the dart hits the target.

According to the above configuration, when an object other than the dart (for example, the player's hand or finger, etc.) is reflected, it is possible to detect the action of the player directly inserting the dart into the target with his hand, or when the dart is inserted into the target. When the depth of hitting the target is not reached, the moment when the hand is strong from behind the dart The act of hitting the ground and inserting it to the end to be detected as a hit, etc., is judged as cheating.

For example, when it is determined that there is a possibility of cheating, the cheating determination unit 106 may update the cheating detection count indicating the number of times that the possibility of detecting the cheating and the determination are made. Specifically, the cheating determination unit 106 can be updated by increasing the cheating detection count.

The cheating determination unit 106 may determine whether the cheating detection determination count is more than a specific count (for example, the first specific number of times in each game and the second specific number of times in each round) for each game or each round. (1) Output the throwing result of the game execution unit 100 (for example, the judgment of the dart hitting the dart board 12, the judgment of the position where the dart pierced the target 18, the result of calculation of the score, etc. The same applies hereinafter); (2) ) outputting a cheating detection alarm indicating a warning that the intent of cheating was detected; (3) repeating the throw without any response to the throwing result; (4) outputting as a throwing result indicating that the dart did not hit the target 18 and failed to hit the target 18 At least one of (1)~(4) of the subject of the score is "OUT".

For example, the cheating determination unit 106 may determine (1) above when the cheating detection determination count for each game (hereinafter referred to as "the number of cheating detection determinations (game)") has not reached the first specific number of times, and the cheating detection determination count will be determined as the number of cheating detection determinations in the above-mentioned (1). When the (game) is more than the first specified number of times, and when the count of cheating detection judgments per round (hereinafter referred to as "cheating detection judgment times (rounds)") does not reach the second specified number of times, it is determined as the above (2) and (3) ), when the number of cheating detection determinations (games) is equal to or more than the first specified number of times, and the cheating detection determination count per round is equal to or more than the second specified number of times, it will be determined as the above (4).

According to the above configuration, there can be a range of the number of times determined as cheating, and it can be used for multiple times The player who cheated can reduce the target, and output the result of "OUT" that does not score and re-roll, but can output the judgment result of suppressing the cheating.

When the cheating determination unit 106 determines that the player has a possibility of cheating, the game execution unit 100 may not count the points. When the cheating determination unit 106 determines that the number of times that the player has the possibility of cheating exceeds a predetermined number of times, the game execution unit 100 may determine that the player cheated without counting points.

The image analysis unit 108 has a function of analyzing still images or moving images. The image analysis unit 108 analyzes, for example, an image captured by the player's camera, and determines whether or not the dart game is being played correctly based on a specific reference. The so-called specific reference is a reference indicating that the dart game is performed correctly, for example, a reference indicating that the player who should throw (the current throw) generally throws darts from the vicinity of a specific position in front of the dart game apparatus 10. As examples of the dart game not being played correctly based on a specific standard, specifically, the player does not exist in a specific area in the photographed image, and there is a current-round throw in a specific area in the photographed image. Throwing darts, etc., by a person other than the player, or by a person who is not a player who should be thrown. The so-called specific area is an area where the presence of the player can be confirmed when the player throws darts from the vicinity of a specific position immediately before the dart game apparatus 10 . Moreover, as for the specific area, what is necessary is just to set suitably the area|region which allows a player to exist when throwing from a specific position.

The image analysis unit 108 can extract, for example, the feature of the captured image and match it with a feature pattern indicating that the player throws darts based on a specific reference pre-registered in the memory 34 or the like, and in the image , to analyze whether the player throws darts according to a specific benchmark. for this score For analysis, prior techniques such as person recognition can be used.

The image analysis unit 108 analyzes, for example, an image captured by the target camera, and determines whether or not an object other than a dart is reflected in the image within the second predetermined time. For example, the image analysis unit 108 can extract the features of the captured image, match it with a feature pattern representing at least a part of the darts pre-registered in the memory 34 or the like, and analyze whether or not any other than the darts is reflected in the image. object. For this analysis, prior techniques such as image recognition can be used.

<action>

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. 5 to 8 . Repeat this action each time you throw the dart. In addition, the order of the process shown below is an example, and it can change suitably.

FIGS. 5 to 6 show an example of the action of detecting cheating by using the hit detection sensor and the impact sensor 20 and making a judgment. The process shown in FIG. 5 and the process shown in FIG. 6 are represented by the same symbols. connectors are connected to each other.

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

The dart game apparatus 10 determines whether the time of the detection signal from the displacement sensor 22 satisfies the second condition longer than a specific reaction time (step S11).
