Description

[Technical Field]

[0001] The present invention relates to a system for inspecting nails to be driven into pachinko gaming machines, and more particularly to a pachinko nail inspection system that can automatically determine from a photographed image whether or not a nail has been driven into an accurate position and output the result. [Background technology]

[0002] Devices have been developed and used to inspect the nails that are driven into pachinko machines. Since even a slight misalignment of the nails in pachinko machines can affect the number of balls dispensed, nails must be driven into the machine in the correct position and at the correct angle to ensure fairness.

[0003] For example, Japanese Patent Application Laid-Open No. 2014-117510 discloses a technology for inspecting nails in pachinko machines. The technology acquires nail state data, which numerically indicates the state of the game nails, and machine tilt data, which indicates the machine tilt angle of the target machine, based on an image of the game area captured from the front side of the target machine. It also acquires machine information data, which indicates the model name of the target machine, and stores the data as machine evaluation data. The technology then determines the evaluation value of the target machine based on the machine evaluation data. The technology discloses that it is possible to provide a nail state determination device that can accurately and quickly determine the state of the game nails.

[0004] While this technology certainly makes it possible to determine the condition of the game nails, there are problems such as difficulty in making an accurate determination depending on the photographing position and the angle at which the nails are driven, and the need to use specialized equipment for the photographing device, which makes it expensive.

[0005] Therefore, there was a need for the development of a nail detection system for pachinko machines that would be able to determine the state of the nails in pachinko machines simply by taking still images and videos using a smartphone or other device. [Prior art documents] [Patent documents]

When doing so , When the head position of a specific nail acquired by the nail position acquisition means is within the range of the corresponding accurate nail head position stored in the storage means, if the head position of another nail on the image is out of the range of the corresponding accurate nail head position stored in the storage means, a comparison is made to determine that the mutual nail head positions do not match, No match on video or image current Nail head position and accurate head position The accuracy of the pouring position is determined and evaluated by outputting the above information on the image.

[0010] Furthermore, the pachinko nail inspection system is equipped with an artificial intelligence system, which sequentially saves accurate nail head position information in the board information of the pachinko game machine and information related to whether the nail head positions acquired by the nail position acquisition means match or mismatch, and calibrates the head positions of each nail acquired by the calibration means using a learning function based on the saved information.

BEST MODE FOR CARRYING OUT THE INVENTION

[0013] The pachinko nail inspection system according to the present invention will be described in detail below with reference to the embodiments shown in the drawings. Fig. 1 is a schematic diagram of the pachinko nail inspection system, and Fig. 2 is a diagram showing the process of determining the nail driving position.

[0015] The photographing means 100 is a means for photographing the surface 12 of the pachinko game machine 10 from the front to obtain video or still images, and in this embodiment, it is configured to use a small portable photographing device such as a digital camera or a camera equipped on a smartphone or tablet device, but is not limited to this, and it is also possible to configure it so that the nail position can be calculated more accurately by using a dedicated photographing device capable of taking high-resolution photographs.

[0016] The storage means 200 is a means for storing and holding moving images or still images captured by the imaging means 100. In this embodiment, the storage means 200 is made up of a memory installed in a smartphone or a computer (not shown), and is configured to read and write data by issuing commands from a computing device (not shown) installed in these devices, thereby storing, saving, and reading out information, but is not limited to this configuration. For example, the storage means 200 may be configured to connect to an external device such as a server via the Internet or the like, and to read and write data from and to a storage device of the server or the like, thereby storing, saving, and reading out information.

[0017] The nail position acquisition means 300 is a means for acquiring the head position of each nail 14 driven into the board 12 from a video or still image of the board 12 of the pachinko gaming machine 10 captured by the imaging means 100, or for acquiring accurate information on the basic nail head positions by importing it from another device. In this embodiment, the nail position acquisition means 300 is made up of software, and an executable file is stored in a storage means 200 equipped in a smartphone or computer. The computing device reads the executable file from the storage means 200 and performs a comparison process to acquire the head position of each nail 14 driven into the board 12, but is not limited to this configuration, and the nail position acquisition means 300 may be configured using dedicated imaging equipment equipped with a storage means or the like.

[0018] The determination means 400 is a means for determining whether the head position of each nail 14 acquired by the nail position acquisition means 300 is accurate. In this embodiment, the determination means 400 is made up of software, and an executable file is stored in a storage means 200 equipped in a smartphone or a computer. The calculation device reads the executable file from the storage means 200 and executes it to determine whether the acquired head position of each nail 14 is accurate. However, the configuration is not limited to this, and the determination means 400 may be configured using a dedicated photographing device equipped with a storage means or the like. Also, for example, the determination means 400 may be configured to be connected to an external device such as a server via the Internet or the like, store the executable file of the determination means 400 in the storage device of the server, and have the calculation device of the server or the like execute the executable file.

[0019] In this embodiment, the storage means 200 stores the current board information of the pachinko gaming machine 10, and also stores the accurate head position information P of the nails 14 on the board 12 in advance. AThe current board information of the pachinko gaming machine 10 is acquired from video or still images captured by the imaging means 100. In addition, the accurate head position information of the nails 14 on the board 12 is previously input from the outside as image information of the board 12 of the corresponding pachinko gaming machine 10 on which the accurate nail positions are displayed, and is then stored.

[0020] The nail position acquisition means 300 performs image processing on the board information consisting of a moving image or a still image taken by the photographing means 100 to acquire the head position of each nail 14, and then outputs head position information P of the nail 14 as a video or image. T This is a configuration that holds the above.

[0021] When a video or still image is captured, a deviation occurs at the edge due to the distance and angle from the shooting point. There is also a possibility of distortion due to the influence of the lens. In this embodiment, image processing is performed to identify the nail position of the nail 14 located at the edge of the video or still image by taking into account the distance and angle from the shooting point and distortion caused by the lens. The calibration process for this data will be described later. In this embodiment, the head position is acquired by recognizing a part in the video or image that has a shape and color that can be recognized as the head of the nail 14 as the head position of the nail 14, and then superimposing it on the video or image to generate head position information P T However, the present invention is not limited to this configuration.

[0022] The determination means 400 is a means for inspecting and evaluating whether the nail 14 is accurately placed on the board surface 12. In this embodiment, the determination means 400 uses the current head position information P of the nail 14 acquired by the nail position acquisition means 300. T and accurate nail head position information P stored in the storage means 200. A The comparison method is to compare the current head position information P of the nail 14 on the video or image. T and accurate nail head position information P AThe system compares the images and determines whether the nail head positions match. After that, the mismatched nail head positions are output by highlighting them on the image, thereby determining and evaluating the accuracy of the nail driving positions.

[0023] This configuration makes it possible to inspect the installation position of nail 14 based on still images and videos taken using a device such as a smartphone, making it possible to obtain the accurate installation position of the nail with a simple configuration.

[0024] In this embodiment, the nail position acquisition means 300 is configured to include the calibration means 310, as described above. The calibration means 310 is a means for calibrating the acquired head position of each nail 14 by shifting it to a more accurate head position, and acquires the head position of each nail 14 recognized and acquired by the nail position acquisition means 300 and the angle and distance formed by the imaging means 100 as basic data D, then performs calculation processing and performs a process of shifting the acquired head position of each nail 14 to a more accurate head position for calibration. With this configuration, it is possible to acquire the accurate driving position of the nails.

[0025] Next, a description will be given of the determination process performed by the determination means 400. In this embodiment, the accurate nail head position information P A is configured from range information consisting of approximately circular shapes defined at locations corresponding to each nail. This makes it possible to determine the driving position of the nail 14 through simple processing.

[0026] Specifically, the determination means 400 first determines whether the head position of a specific nail 14 acquired by the nail position acquisition means 300 is within the approximately circular head position range of the corresponding accurate nail stored in the storage means 200. If it is determined that it is within the head position range, it then determines whether the head positions of other nails 14 are within the head position range of the corresponding accurate nail stored in the storage means 200. If it is determined that it is outside the head position range of the accurate nail, it determines that the head positions of the mutual nails do not match, and outputs on the image the head position of the current nail 14 that does not match the accurate head position. With this configuration, it is possible to partially inspect the board surface 12 of the pachinko gaming machine 10.

[0027] The pachinko nail inspection system 1 according to the present invention is configured to include an artificial intelligence system 20. In this embodiment, the artificial intelligence system 30 obtains accurate nail head position information P in the board information of the pachinko gaming machine 10. A and the nail head position information P acquired by the nail position acquisition means 300 A The system is equipped with a learning function that sequentially saves information related to whether the nails match or mismatch, and then calibrates the head position of each nail acquired by the calibration means based on that saved information. This configuration makes it possible to accumulate and learn calculation information related to nail driving positions, enabling more accurate calculation processing of driving positions.

[0028] The pachinko nail inspection system 1 according to the present invention can be configured to store the inspection results of each machine, as inspection data, in storage means 200 to determine whether the nail head position is within the correct range, and to include analysis means (not shown) that acquires business data such as the number of balls dispensed and the number of times each machine is used, and analyzes the correlation between the inspection data and the business data. The analysis means may be installed in a device such as a smartphone, or may be installed in an external computer. This configuration makes it possible to analyze how nail misalignment affects business performance, and this information can be used as basic information for conducting sound management.
