Description

The present invention relates to an unauthorized operation detection device and a program executed in an unauthorized operation detection system.

Conventionally, in a gaming machine such as a pachislot gaming device or a pachinko gaming device, for example, a foreign object such as a piano wire is inserted into a housing from a gap generated between a side portion of the upper door and a side portion of the lower door. It is a so-called goto that attempts to obtain a large number of game media illegally, such as an act of illegally operating a control board or the like, or an act of illegally exploiting a game medium by inserting a foreign object from a game medium discharge port. Action may be performed. If such an act is performed, not only will the profits of the amusement shop side be significantly reduced, but such an act is the object of theft and is not allowed in the first place.

On the other hand, there is conventionally a technique for detecting the operation of an apparatus or a person from an image captured by an imaging unit such as a monitor camera (see, for example, Patent Documents 1 to 5). In Patent Document 1 and Patent Document 2, an image of an operation that the robot should operate based on the shape of the robot and the position of the robot and the monitor camera is created, and this image is actually captured by the monitor camera. An apparatus is described for investigating differences compared to motion images. Patent Documents 3 and 4 describe an image pickup apparatus that performs image pickup by operating a shutter when the brightness of a preset mark changes beyond a threshold value. Further, Patent Document 5 compares a motion pattern of a person imaged by an imaging member with a preset motion pattern, and a signal corresponding to the matched motion pattern (for example, turning on / off a predetermined device) A life support device that outputs a signal for turning off) is described.

Conventionally, there is a technique for monitoring a goto action performed in a game hall with a monitor camera or the like (see, for example, Patent Documents 6 to 8). Patent Document 6 and Patent Document 7 describe imaging a blind spot that is easily formed between a pachinko machine and a player. Further, Patent Document 8 stores face data of a person who has performed an illegal act registered in advance, and collates it with the face data of the player imaged by a camera provided at the entrance of the game hall. A player verification system that outputs results to a host computer is described.

Surveillance cameras such as Patent Document 6 and Patent Document 7 are for detecting fraud by visual observation, and cannot detect fraud. Therefore, although it is possible to preserve the evidence of fraud by storing the video, there has been a problem that the store clerk and the like must always monitor the monitor and the like, and the labor cost increases. In addition, in order to detect fraud effectively, there is a problem in that it is necessary to take measures to provide a detector for goto in each gaming machine. In addition, if one such detector is provided for each gaming machine and this detector is periodically replaced with a new one, the number of parts increases and the labor cost for installation increases. There was a problem of enormous volume.
In addition, the player collation system of Patent Document 8 can only recognize the entry of a specific person registered in advance, and excludes a person who has not been registered in advance and tries to perform an illegal act using a conventional method. There was a problem that I could not do it.

The management device 60 includes a CPU 62, a ROM 64, a RAM 66, and a hard disk 68 as storage means.
The ROM 64 is a non-volatile memory, and stores programs executed by the CPU 62 (programs executed in the unauthorized operation detection system of the present invention), data used when the CPU 62 performs processing, and the like. The RAM 66 is a volatile memory, and temporarily stores data corresponding to the processing result of the CPU 62 and the like. The hard disk 68 stores general operation pattern data (see FIG. 5), candidate video data (see FIG. 8), and illegal operation pattern data (see FIG. 9) described later.

An imaging device 72 is connected to the CPU 62 via an input device 74, a display device 76, and an interface circuit 70.

The display device 76 can display an image based on the image data transmitted from the imaging device 72 or an image based on the candidate video data stored in the hard disk 68. The imaging device 72 functions as an imaging unit.

The CPU 62 calculates an optical flow, which will be described later, based on the image data received from the imaging device 72 (video data with 10 seconds of image data as one unit), and acquires optical flow data. The optical flow data corresponds to the change mode data in the present invention.

The CPU 62 is connected to the Internet 80 via the communication interface circuit 78. Based on the optical flow data, the CPU 62 determines whether or not there has been an unauthorized operation. If it is determined that there has been an unauthorized operation, the CPU 62 transmits a mail notifying that to the store clerk's mobile phone via the Internet 80. . At this time, the information included in the mail may include information regarding the date and time and the position of the imaging device 72 that is the transmission source of the video data determined to have been operated improperly.

FIG. 5 is a diagram illustrating an example of general operation pattern data.
The general operation pattern is a general operation that can be performed by the player in the game hall. For example, an operation of inserting a medal into the medal slot 22 of the pachislot gaming device 1, an operation of operating the start lever 6, and a stop button 7 The operation | movement etc. which operate (7L, 7C, 7R) can be mentioned. In the present embodiment, the general operation pattern data indicating the general operation pattern is optical flow data represented by an optical flow.
An optical flow is a velocity vector between pixels in an image. As a method of calculating the optical flow, first, a pixel block composed of a plurality of pixels is set in advance in the first image. Next, this pixel block is detected in the second image following the first image. Then, the movement of each pixel block in the two images is detected. Thereby, the optical flow of the object in the imaging region of the imaging device 72 can be calculated.

As shown in FIG. 5, the hard disk 68 stores general operation pattern data including stop operation pattern data, start operation pattern data, and medal insertion operation pattern data. Hereinafter, the stop operation pattern data A will be described with reference to FIGS. 6 and 7. The stop operation pattern data A includes stop operation pattern data a1, stop operation pattern data a2, stop operation pattern data a3, stop operation pattern data a4, and stop operation pattern data a5.

6 and 7 are diagrams for explaining the optical flow.
The diagram on the left side of FIG. 6A is a diagram illustrating the state of the pachislot gaming device 1 and the player's hand 40 imaged by the imaging device 72.
In the image obtained by the imaging device 72, the stop button 7 (7L, 7C, 7R) of the pachislot gaming device 1 and the player's hand 40 are displayed.

The diagram on the right side of FIG. 6A is a diagram showing an optical flow in the state of the diagram on the left side of FIG.
The imaging device 72 transmits image data to the management device 60 every 0.5 seconds. Then, the management device 60 calculates an optical flow every 0.5 seconds from each transmitted image data. In the diagram on the right side of FIG. 6A, the optical flow is not obtained. This indicates that the video has not changed from 0.5 seconds ago to the present time.

The diagram on the left side of FIG. 6B is a diagram showing a state after 0.5 seconds from the state of the diagram on the left side of FIG. 6A, and the diagram on the right side of FIG. It is a figure which shows an optical flow in the state of the figure on the left side of b).
6B, the left side of FIG. 6A except that the player's hand 40 has moved from the state of the left side of FIG. 6A to a position where the player presses the stop button 7L. It is the same as the figure.
In the diagram on the right side of FIG. 6B, an optical flow indicating that each pixel block P (P1 to P3) at the position where the hand 40 is displayed has been moved upward is obtained. This is because each pixel block P has moved upward from 0.5 seconds ago (the state in the left diagram in FIG. 6A) to the present (the state in the left diagram in FIG. 6B). It is shown that. The data indicating the optical flow corresponds to the stop operation pattern data a1.

6C is a diagram showing a state after 0.5 seconds from the state of the left diagram of FIG. 6B, and the diagram on the right side of FIG. 6C is FIG. It is a figure which shows an optical flow when it is in the state of the left figure of c).
6C, the player's hand 40 moves from the state of the left side of FIG. 6B to the front side of the stop button 7C (below the stop button 7C in the figure). Except for this, it is the same as the diagram on the left side of FIG.
In the diagram on the right side of FIG. 6C, an optical flow indicating that each pixel block P (P1 to P3) at the position where the hand 40 is displayed has moved to the lower right side is obtained. This is because each pixel block P is placed on the lower right side from 0.5 seconds ago (the state in the left diagram in FIG. 6B) to the present (the state in the left diagram in FIG. 6C). Indicates that it has moved. The data indicating the optical flow corresponds to the stop operation pattern data a2.

Similarly, FIG. 7A shows a state 0.5 seconds after the state of FIG. 6C, and FIG. 7B shows a state 0.5 seconds after the state of FIG. Shows a state 0.5 seconds after the state of FIG.

The series of operations from FIG. 6A to FIG. 7C is performed in 2.5 seconds as a whole. The operations from FIG. 6A to FIG. 7C include all of the stop operation patterns a1 to a. Accordingly, the series of operations from FIG. 6A to FIG. 7C are determined to be operations indicated by the stop operation pattern data A, and are determined to be general operations.
In the present embodiment, all of the optical flow data corresponding to the stop operation pattern data a1 to the stop operation pattern data a5 is included in the optical flow data (10 optical flow data) obtained from the video data of 10 seconds. If it is determined that the stop operation pattern data A1 to the stop operation pattern data a5 are detected in any order, it is determined that the stop operation pattern data A is the stop operation pattern data A. It may be determined that the stop operation pattern data A is obtained in the order of a1, a2, a3, a4, and a5. That is, in the present invention, when the general motion pattern data is composed of a plurality of motion pattern data, when the order in which the plurality of motion pattern data is detected is constant, the general motion pattern data is determined to be the general motion pattern data. Alternatively, if all of the plurality of operation pattern data are detected, the general operation pattern data may be determined regardless of the detection order.

The stop operation pattern data B shown in FIG. 5 is optical flow data corresponding to the case where the operation described with reference to FIGS. 6 and 7 is performed for 5 seconds. That is, the length of the optical flow vector indicated by the stop operation pattern data B is half that of the stop operation pattern data A. In addition, although not shown, data indicating a stop operation pattern that the player can perform in the stop operation is stored in the hard disk 68 as stop operation pattern data.

FIG. 8 is a diagram illustrating an example of candidate video data.
The hard disk 68 stores candidate video data as shown in FIG. The candidate video data is video data recorded on the hard disk 68 when the player performs an operation that does not match a general operation pattern and an illegal operation pattern described later. When the management device 60 determines that there is a change in the video imaged by the imaging device 72, video data for 10 seconds from that point is temporarily stored in the RAM 66. Then, optical flow data is acquired from the video data and compared with general operation pattern data and illegal operation pattern data described later. If there is an operation pattern that does not correspond to the general operation pattern or the illegal operation pattern in the 10-second image, this image data is stored as candidate image data.

FIG. 9 is a diagram illustrating an example of illegal operation pattern data.
The hard disk 68 stores illegal operation pattern data as shown in FIG. The unauthorized operation pattern data is data indicating an unauthorized operation pattern that can be performed by the player in the game hall. The administrator can play back the candidate video data described with reference to FIG. 8 to view the video, and if it is determined that the operation displayed in the video is an illegal operation, the administrator can register it. When there is a registration input, the management apparatus 60 acquires optical flow data from the candidate video data, and stores this optical flow data as unauthorized operation pattern data.

FIG. 10 is a flowchart showing a subroutine of the illegal operation detection process performed in the management device that constitutes the illegal operation detection device.
The imaging device 72 continuously captures an imaging range H (see FIG. 2), and image data is constantly transmitted from the imaging device 72 to the management device 60 every 0.5 seconds. Yes. Imaging the inside of the game hall with the imaging device 72 under the control of the management device 60 corresponds to an imaging step.

First, the CPU 62 acquires optical flow data based on the image data transmitted from the imaging device 72, and determines whether or not an operation has been detected based on whether or not an optical flow exists (step S10). If it is determined that no operation has been detected, this subroutine is terminated. Note that, in this embodiment, if an optical flow (vector) exists, a case where an operation is detected regardless of the vector length will be described. However, the present invention is not limited to this example. If there is a movement of 5 cm or more in 0.5 seconds, it may be determined that the operation is detected when the movement amount is a predetermined amount or more, such as determining that the operation is detected.

When determining that the movement is detected in step S10, the CPU 62 sets the elapsed time T = 0 and starts measuring the elapsed time (step S12).

Next, the CPU 62 temporarily stores the image data obtained by imaging by the imaging device 72 in the RAM 66 (step S14), and continuously repeats this until T = 10 (step S16: NO). If T = 10 (step S16: YES), the process proceeds to step S18.

In step S18, the CPU 62 acquires optical flow data from video data composed of image data obtained for 10 seconds. In this process, the CPU 62 obtains optical flow data by calculating an optical flow every 0.5 seconds from the video data. When executing the process of step S18, the CPU 62 functions as a change mode data acquisition unit. Moreover, the process of step S18 is corresponded to a change mode data acquisition step.

Next, in step S <b> 20, the CPU 62 determines whether or not the obtained optical flow data matches any of the general operation pattern data stored in the hard disk 68. When performing the process of step S20, the CPU 62 functions as a first determination unit. If it is determined that the optical flow data matches the general operation pattern data, this subroutine is terminated.
In the present specification, the optical flow data and the general motion pattern data (or the illegal motion pattern data) coincide with each other when the optical flow data and the general motion pattern data (or the illegal motion pattern data) digitized by a predetermined process. And the value is within a predetermined range (high similarity).

When determining in step S20 that the optical flow data does not match the general operation pattern data, the CPU 62 determines whether or not the optical flow data matches the illegal operation pattern data stored in the hard disk 68 (step S22). . If it is determined that the optical flow data does not match the illegal operation pattern data, the CPU 62 stores the video data temporarily stored in the RAM 66 in step S14 in the hard disk 68 as candidate video data for illegal operation (step S24). Exit the subroutine. When executing the process of step S22, the CPU 62 functions as a determination unit and a second determination unit. Further, the process of step S2 corresponds to a determination step and a second determination step. Further, when executing the process of step S24, the CPU 62 functions as a candidate video data storage control unit. Further, the process of step S24 corresponds to a candidate video data storage step.

If it is determined in step S22 that the optical flow data matches the illegal operation pattern data, the CPU 62 performs a process of sending a notification mail to the mobile phone owned by the store clerk via the Internet 80 (step S26), and ends this subroutine. To do. When executing the processing of step S26, the CPU 62 functions as a notification processing means. The process of step S26 corresponds to a notification step.

FIG. 11 is a flowchart showing a subroutine of registration processing performed in the management apparatus.
This process is executed when there is an input from the input device 74 to start the registration process by an operation of an administrator or the like.
First, in response to an input from the input device 74, the CPU 62 reproduces one of the candidate video data stored in the hard disk 68 in step S24 (see FIG. 10) (step S40).

Next, in step S <b> 42, the CPU 62 determines whether or not there is a registration input from the input device 74. If it is determined that there is a registration input, the CPU 62 acquires the optical flow data from the candidate video data (step S44), and stores this optical flow data in the hard disk 68 as the illegal operation pattern data (step S46). When executing the process of step S46, the CPU 62 functions as a setting means. Moreover, the process of step S46 functions as a setting step. When it is determined in step S42 that there is no registration input, or after the process of step S46, this subroutine is terminated.

As described above, according to the unauthorized operation detection device 100 and the program executed in the unauthorized operation detection device 100, the pachislot gaming device 1 is provided with a detector for detecting the goto action, or the number of shop assistants is increased to monitor the goto action. It is possible to detect the goto action without having to do it, and the store clerk at the amusement store recognizes that the goto action has occurred by sending a notification email to the mobile phone owned by the store clerk. Can do. Therefore, it is possible to detect the goto action more reliably without incurring labor costs.

In addition, since the goto action is discovered using the video data obtained by imaging by the imaging device 72, it is not necessary to newly provide a detector when installing the pachislot gaming device 1 anew. In addition, every time a new goto action is discovered, it is no longer necessary to inform the store clerk what kind of goto action has occurred. Therefore, even when a new pachislot gaming apparatus 1 is introduced, it is possible to detect the goto action more reliably without incurring labor costs.

In addition, when it is determined that no illegal operation has been performed, the video data is stored as candidate video data for illegal operation, and optical flow data acquired from the candidate video data is illegally operated by external input. Set to pattern data. Therefore, if the amusement store confirms the video and determines that it is an illegal operation, the optical flow data acquired from the candidate video data is illegally operated by operating the input device 74 and performing a predetermined input. Can be set to pattern data. As a result, new illegal operation patterns can be registered at any time, and it becomes possible to respond quickly to a new Goto method. In addition, since illegal operation is detected and stored based on the optical flow data and illegal operation pattern data obtained from the video data, the correspondence between the illegal operation and the video associated with the operation is clearly defined. Become. Therefore, it is possible to reduce the need to verify later whether or not the act performed on the captured image is an act that has been detected fraud, and prove the goto action without taking time. Is possible. In addition, since it is possible to store the video data when it is determined that no unauthorized operation has been performed, it is easy to investigate illegal activities by viewing the video. In particular, when illegal operation pattern data is set by viewing candidate video data, it is not necessary to check the video over a long period of time, compared to the case of always storing video data. Setting (registration) can be performed.

In addition, since the video data is data indicating a video having a length of 10 seconds and the amount of data when compared with the operation pattern data (illegal operation pattern data or general operation pattern data) is limited, the data is The comparison process can be easily performed.

In the present embodiment, the case where it is determined whether or not an illegal operation has been performed using the optical flow has been described. However, in the present invention, information on the operation of the player (person) is acquired from the video data, and this information is obtained. If it is determined whether or not an illegal operation has been performed based on the above, it is not limited to this example. As a method for detecting the movement of the person itself from the video data, a conventionally well-known technique can be adopted. For example, a method in which the person wears a marker and detects the movement of the marker can be mentioned. When using a marker, it is determined that there was an illegal action when a movement of something other than the marker was detected even though the movement of the marker was not detected. When it is detected that the movement other than the pattern is detected, it may be determined that there is no illegal operation. In this case, for example, it is necessary for the player to wear a marker on a finger or the like. When using a marker, it is preferable to arrange the imaging means so as to stretch around the room. This is because it is possible to prevent the marker from being hidden by the orientation of the person's body and to detect the movement reliably. Further, an infrared camera may be used as the imaging means, and a marker that reflects or emits infrared light may be used.
Furthermore, in the present invention, a transmitter generates a magnetic field in the room, and a person wears a magnetic sensor as a marker. It is good also as detecting the motion of a sensor by this.

However, in the present invention, the location where the imaging means is installed is not limited to this example. For example, between the gaming machine and the gaming machine It is good also as installing in what is called a sand machine in which a game medium is lent by being inserted into money. Further, in the present embodiment, the case where the imaging device 72 is provided in association with each one of the pachislot gaming devices 1 has been described. However, in the present invention, the imaging means is particularly capable of imaging the inside of the game hall. For example, one unit may be associated with each of a plurality of gaming machines or may not be associated with a gaming machine.

In the present embodiment, a case has been described in which a notification mail is transmitted to a mobile phone owned by a store clerk to notify that an unauthorized operation has been performed. However, the processing for notification in the present invention is notified to the outside. However, the process is not limited to this example. For example, a process for outputting a sound such as a warning sound or a warning message from a speaker provided in a gaming machine or a game hall (for example, a warning sound is output to a gaming machine). A process of transmitting a signal for output), or a process of providing a warning lamp in a gaming machine or amusement hall and blinking the warning lamp.

In the present embodiment, the case where the pachislot gaming apparatus 1 is installed in the game hall, that is, the case where the game hall is a game hall of a game shop related to the pachislot game has been described. However, the game hall in the present invention is not limited to this example, and is, for example, a game hall such as a game shop (pachinko shop) related to pachinko games or a facility (game center) in which a game device (video game device) is installed. Can be mentioned. When the game hall is a pachinko parlor game hall, the shooting means including the launch lever including the player's hand, the game ball slot, and the game ball payout port shall be imaged by the imaging means. In the case of a center game hall, it is preferable to take an image so that an imaging panel includes an operation panel on which operation levers, operation buttons, and the like are arranged, and a coin slot.
