Abstract

To provide a firing training system that can conduct a training while adjusting a target position or a firing attitude in shooting of a next bullet by knowing an impact position in real time.SOLUTION: A target is projected to a rubber-type sensor 39 of a target device 3 with a projector 40 by sending image data of the target from a terminal 7 to the projector 40. A shooter conducts firing training relative to the target projected on the sensor. The terminal receives a firing training result conducted by the shooter as detection signals of the sensor, calculates an impact position, generates image data of the impact position and scores, and sends the generated image data of the impact position and scores to the projector. The projector superimposes the image of the impact position and scores to the target image and projects to the rubber-type sensor. The shooter can thus conducts the firing training while viewing the firing target and the firing result.SELECTED DRAWING: Figure 4A

Description

  The present invention relates to a shooting training system, and more particularly to a technique for displaying a landing result on a target in shooting training.

  Conventionally, systems for shooting training have been proposed. In these shooting training systems, when a trainee fires at a target and the target lands, the coordinates (X, Y) from a sensor that detects the landing position are acquired and installed near the commander or shooter. Display the result on the monitor of the terminal. For example, the shooting training system disclosed in Patent Literature 1 is a shooting training system using a laser gun, and performs scoring according to the position at which a light bullet emitted from the laser gun lands on a target plate. In the target device disclosed in Patent Literature 2, coordinate data of a bullet hole position of a hit bullet hitting a target surface is detected by a video camera. In the shooting training system using live ammunition disclosed in Patent Literature 3, the area detection sensor detects an impact in a wider range than the target.

  In the conventional system such as Patent Document 1, since the shooting result is displayed on the monitor of the terminal installed near the shooter and the commander, the shooter indirectly checks the impact point of the target by looking at the monitor of the terminal. And cannot directly know the impact position on the target. Therefore, it is difficult to improve the training efficiency by performing the training while sequentially correcting the target position and the shooting attitude when the next bullet is fired.

  An object of the present invention is to solve the above-described problems, and enable the shooter to directly know the impact position at the time of shooting training, thereby performing training while correcting the target position and shooting attitude at the time of firing the next shot. To provide a shooting training system.

  In order to achieve the above object, the present invention provides a shooting training system, which includes a target device including a detector for detecting impact on a target, a projector for projecting the target onto the target device, and a target device and a projector. And a terminal capable of communicating with the terminal, the terminal generates and transmits image data for projecting the target to the projector, and stores a score table corresponding to the target, and receives a detection signal of the detector. And a control unit for calculating a landing position and a score. The control unit generates image data for projecting the landing position and the score on the target device based on the calculated landing position and the score, and transmits the image data to the projector. In addition, the projector provides a shooting training system configured to project the impact position and the score by superimposing it on the target.

  By projecting the shooting result on the target, the shooter can shoot while looking at the target and the shooting result. Since the next shot can be fired while checking the shooting result displayed on the target, the target position and the shooting attitude can be corrected while keeping the line of sight fixed to the target.

FIG. 14 is a diagram illustrating an example of changing a color display of a projection image according to the second embodiment.

  Hereinafter, prior to describing an embodiment of the present invention, a configuration of a conventional shooting evaluation system will be described.

  FIG. 1 is a diagram showing an apparatus configuration of a conventional shooting evaluation system. The shooter 1 uses a firearm 2 such as a gun to fire a live ammunition toward a target 4 provided on a target device 3 to perform training. The impact position is detected by the detector 5 of the target device 3, and is notified to the terminal 7 installed near the shooter, so that the impact position is displayed on the monitor. In addition, the terminal 7 can set the training conditions of the information at the time of training (target used, used firearm, etc.). The terminal 7 is installed near the shooter 1, and the shooter 1 can check the landing position, the score, and the like even if there is a distance between the shooter 1 and the target 4. The terminal 7 and the control device 6 of the target device 3 input and output data wirelessly or the like.

  A configuration example of the target device 3 will be described with reference to FIG. FIG. 2 is a front view of the target device 3 shown in a side view in FIG. The target device 3 includes a target 4, a detector 5, and a control device 6. The target 4 has a plate-like shape such as a silhouette of a human, and the control device 6 controls the operation such as standing up / falling down. The detector 5 is installed in front of the target 4 and detects the impact of the shooting. The detector 5 can detect the impact on the detection area 21 wider than the target 4 and detect the impact on the detection area 21 irrespective of the impact on the target 4. The detection area 21 is an area on the same plane as the target 4, and an area wider than the target 4 is set. The detector 5 detects the position coordinates of the passing position of the detection area 21 and sets them as landing coordinates. For detecting the position coordinates of the live ammunition, a plurality of sensors for detecting a shock wave, a plurality of ultrasonic sensors, and the like are used. The impact coordinates converted into the XY coordinates in 21 are calculated.

  However, in the case of a firearm with a slow initial velocity, such as a beating gun, the impact position cannot be detected by a sensor that detects a shock wave. In such a case, a rubber type sensor as shown in FIG. 3 can be used. The front and back of the wooden frame 31 are sandwiched between rubbers 32 and 33, and a plurality of sensors 34 provided below the wooden frame detect the passage position of bullets. When the bullet passes through the rubber, the shock wave of the bullet is detected by a plurality of sensors such as an acoustic sensor and an ultrasonic sensor. Based on the time when the plurality of sensors detect the shock wave and the positional relationship between the sensors, the XY in the detection area 35 is determined. The impact coordinates converted into the coordinates are calculated. It is desirable that the rubbers 32 and 33 be made of a self-healing material capable of contracting and contracting a through hole when penetrating a bullet. As a target in this case, a target paper shaped like the target 4 is stuck on the rubber.

  At the time of impact, the impact position, time, score, and the like are displayed on the terminal 7, and the shooter can obtain a shooting result by looking at the monitor of the terminal 7. With respect to display on a monitor, one disclosed in Patent Document 3 is known. Scores are automatically calculated and the total score can be displayed. In Patent Literature 3, a score corresponding to the coordinates calculated by the landing position calculation unit is calculated. In such a shooting evaluation system, scoring according to the outer diameter of the bullet centering on the impact position can be performed based on the impact coordinates calculated from the detection result of the detector 5 and the caliber size of the firearm.

  However, in such a conventional shooting evaluation system, when the rubber type sensor of FIG. 3 is used, a target sheet is attached to the rubber, so that it is difficult to change the position of the target which is the shooting target. Also, since the result of the impact is displayed on the monitor of the terminal installed near the shooter or commander, the impact position on the target cannot be known directly, and the target position and It was difficult to carry out training while constantly correcting the shooting position.

  First Embodiment A first embodiment is an example of a shooting training system that projects a target using a projector that is a projection device. That is, the present embodiment is a shooting training system, a target device including a detector that detects impact on a target, a projector that projects the target on the target device, and a terminal that can communicate with the projector and the target device. The terminal has a storage unit that stores a score table corresponding to the target, and generates and transmits image data for projecting the target to the target device to the projector, receives a detection signal of the detector, and receives a landing position. And a control unit for calculating the score, based on the calculated landing position and the score, the control unit generates image data of the landing position and the score for projecting on the target device, and transmits the image data to the projector. 1 is an embodiment of a shooting training system that projects a landing position and a score by superimposing on a target.

  FIG. 4A shows an apparatus configuration of the shooting training system according to the first embodiment, and FIG. In the shooting training system of the present embodiment, the projector 40 is used to project a target image on the surface of the rubber type sensor 39 of the target device 3. Here, the rubber-type sensor 39 is obtained by adding a control device for transmitting and receiving data to and from the terminal 7 by radio or the like, in addition to the rubber-type sensor shown in FIG. As for the target image to be projected on the rubber type sensor 39, the terminal 7 transmits target image data and the like to the projector 40, and the projector 40 performs projection using the received image data and video data. Further, the terminal 7 transmits the created landing position and score image data to the projector 40.

  FIG. 4B is a block diagram illustrating one configuration of the terminal 7 of the present embodiment. The terminal 7 can be a PC (Personal Computer), a dedicated machine, or the like, and includes a display unit 41, a power supply unit 42, an input unit 43, a transmission / reception unit 44, a storage unit 45, and a control unit 46. The display unit 41 is an FPD (Flat Panel Display) such as a liquid crystal, and can display a control screen of the shooting system and information on impact. The power supply unit 42 supplies power to the terminal 7. The input unit 43 is a keyboard, a mouse, a touch panel, or the like, and receives an input from an operator of the terminal 7. The printing unit 46-1 is a printer or the like.

  The transmission / reception unit 44 is an interface for transmitting / receiving data between the control unit 46, the target device 3, and the projector 40. The storage unit 45 includes a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), and a nonvolatile memory such as a flash memory. In addition to the program executed by the control unit 46, data necessary for controlling the target device 3 and the projector 40, analyzing landing on the target device 3, and the like are stored. Here, a plurality of score tables 451, a caliber table 452, and a target wear table 453 used for scoring a landing are shown. In the caliber table 452, the caliber of the firearm used in the training is registered in advance. Further, the storage unit 45 stores a landing position, a score, and the like as a result of the past shooting training for each shooter.

  The control unit 46 is configured by a processor such as a CPU (Central Processing Unit), and executes various processing programs stored in the storage unit 45. Here, as a part of the function executed by the control unit 46, a target setting unit 461 that sets a target and generates a target image to be projected on the target device 3, and determines a landing position based on a detection signal received from the target device 3. A landing position calculation unit 462 that calculates and creates image data of a landing position is shown, and a scoring processing unit 463 that calculates a score based on the calculated landing position is shown. These are realized by executing the corresponding processing program. The score table 451 stored in the storage unit 45 corresponds to a target image projected on the rubber-type sensor 39 of the target device 3 and records a score corresponding to an impact point on the target image. The score table 451 is created for each type of target image projected on the target device 3, and the scoring processing unit 463 uses the corresponding score table based on the landing position calculated by the landing position calculation unit 463 to calculate the score. calculate.

  In the conventional configuration shown in FIG. 1, the landing position is displayed on the monitor of the terminal 7 when the target lands during training, but in the present embodiment, the projector 40 The target image, the impact position and the score are projected on the surface of the rubber type sensor 39 of the target device 3. That is, the control unit 46 of the terminal 7 transfers the image data of the landing position and the score in addition to the image data of the target from the transmitting / receiving unit 44 to the projector 40, and the projector 40 superimposes the landing position and the score on the target image. At the same time, it is projected on a rubber type sensor 39. At this time, the landing position calculation unit 462 of the control unit 46 converts the landing position into a circle centered on the calculated landing position coordinates on the target projected on the rubber type sensor 39 and having a size recognizable by the shooter. The converted image data is created, and the projector 40 projects the impact position on the rubber-type sensor 39 using the converted image data. That is, the landing position calculation unit 462 of the control unit 46 converts the landing position into image data of a size that allows the shooter to recognize the landing position on the target device 3 when generating the image data based on the calculated landing position. Is provided.

  FIG. 5 shows a display example of the converted image showing the landing on the projection target, and FIG. 6 shows a processing flow (S1 to S6) from the landing to the display on the projection target. FIG. 5A shows a display example on a monitor of the terminal 7 for comparison, and FIG. 5B shows a display example of a converted image to a rubber-type sensor 39 for projecting a target according to the present embodiment. I have. In the display of the landing position on the side of the rubber type sensor 39 which is the projection target in FIG. 3B, the number of the landing order is displayed, the display color of the last landing point is changed, and the color is determined by the score according to the landing position. May be changed. Also, as shown in (c) of the figure, the converted image of the landing point and the respective score points are displayed, and as shown in (d) of the figure, the converted image of the landing point and the total point are displayed. Alternatively, the landing order may be displayed as shown in FIG. Also, (b), (c), and (d) may be displayed in any combination. That is, when generating the image data of the calculated score, the control unit 46 can generate and display the image data of the total score of the plurality of scores. The display of the converted image of the impact point does not have to be a circular display as shown in (b), (c), (d), and (e), but uses symbols such as arrows, triangles, and crosses. May be displayed. At the end of shooting, a preview function is provided, and the landing positions may be displayed in the order of landing over time as shown in FIG. 7F, and the total score in that case may also be displayed. The preview can be displayed at double speed.

  With the configuration of the shooting training system of the present embodiment, the shooter does not check the impact point indirectly by looking at the monitor of the terminal 7 near the shooter, but is projected on the surface of the rubber type sensor 39 of the actual target device 3. The impact point, the score, and the total point can be directly known on the projected target, and the result of the shooting can be visually recognized on the actual target. Therefore, it is possible to check the habit of the shooter and the points to be noted when shooting while looking at the target. Further, before the start of the training, the impact position, the score, and the total point, which are the shooting results of the shooter in the past stored in the storage unit 45, are superimposed and projected on the projection target on the rubber-type sensor 39. By referring to the shooting results, it is possible to carry out shooting training after analyzing factors and habits of low scores in the previous shooting.

  The display of the shooting result can be performed even after the shooting, but according to the configuration of the present embodiment, the landing result can be displayed in parallel during the shooting. In addition, by using a projection target using the projector 40 instead of a fixed target such as a humanoid target or a target sheet, in one shooting training, training in which the shape and position of the shooting target are sequentially changed is performed. Can be implemented.

  As shown in FIG. 7, at each of 20 seconds, 21 to 40 seconds, 41 to 60 seconds, and 61 to 80 seconds elapsed from the start of the training, the target setting unit 461 of the control unit 46 sets the shooting targets registered in advance. The image frames of the projected image are sequentially projected to confirm the presence or absence of impact (S1). When there is an impact, the coordinates of the impact point are acquired from the sensor 52 (S2). Then, a point of impact is drawn on the target image during training. At the time of displaying the score, a score corresponding to the impact position is acquired from the score table corresponding to the shooting target, and the score is drawn and displayed near the impact position (S3). In other words, when generating the image data of the calculated score, the control unit 46 generates the image data for displaying the score near the impact position, so that the shooter can obtain the projected image on the surface of the rubber type sensor 39. Make it easier to recognize scores.

  As shown in FIG. 7, the score table stores tables A to D for each of the projection images displayed at each elapsed time from the start of the training, and sequentially acquires them. That is, the storage unit 45 stores a score table corresponding to each of the plurality of targets, and the control unit 46 sequentially changes targets to be projected on the target device 3 according to the elapsed time from the start of training, and the scoring processing unit. 463 calculates a score using a score table corresponding to the target that is changed sequentially.

  Similarly, when the target is made to perform the concealing operation with the video, a score table corresponding to the appearance and the extinction can be respectively provided. When a movable target is used, a projection image as illustrated in FIG. 7 may be used, or the same image may be used, and the center point of the display may be moved on the rubber-type sensor 39 and displayed. In this case, it is assumed that the scores in the score table are used by being shifted by the movement of the projection position. When a moving object such as a person, a vehicle, and a ship is targeted, a score table can be provided in accordance with the movement of the moving object that is the target.

  FIG. 8 shows an example of the score table corresponding to the projection image. The left side of FIG. 7 shows a projected image 47 displayed from the start of training in FIG. 7 until 20 seconds, and the corresponding score table 48 is shown on the right side of FIG. For example, a score table 48 of the target image to be displayed in units of 1 mm is generated. The projected image 47 is 30 mm × 30 mm, and has different score distributions in three concentric circles centered on the center, and five points, three points, and one point from the center. In addition, a landing that deviates from that point is scored as zero. The corresponding score table 48 is a table in which the detection area (30 mm × 30 mm) is divided by a 1 mm square frame, and the X coordinate is 0 to 29 and the Y coordinate is 0 to 29. Based on the shape and score of the projection image 47 as a target, a score at a position corresponding to each coordinate of the score table 48 is set.

  At this time, if a line representing the shape of the target (here, three concentric circles) slightly covers the 1 mm square, the higher score among the adjacent scores is set. For this reason, the thickness of the line (the concentric circle in this example) describing the shape of the target also affects the value of the score table 48. In order to consider the thickness of the target line, the score table 48 is generated as a higher score if the line is over 1 mm of the impact detection coordinates. The score table 48 is created in accordance with five points, three points, and one point displayed on the projection image as a target, and records the score corresponding to the landing point.

  Embodiment 2 Embodiment 2 is an embodiment of a shooting training system that updates and projects an image of a projection target itself according to a landing position and a score that are shooting results. That is, in the configuration of the present embodiment, as described in the first embodiment, in addition to displaying the projection image, the landing position, the score, and the total point thereof using the projector 40, the control unit 46 also controls the landing position, The image data of the target projected by the projector 40 on the target device 3 is changed according to the landing conditions such as the score and the total point. The target setting unit 461 of the control unit 46 updates the image of the projection target according to the landing position, the score, and the landing condition, so that the shooter can visually know the training status during the training.

  For example, as shown in FIG. 9, the colors of the projected images are represented by the images A, B, and C corresponding to the total points 0 to 5, 6 to 10, 11 to 15, and 16 to 20 of the shooter's scores. , D, and at the same time, the scores are calculated using the score tables corresponding to the images A, B, C, and D. That is, the control unit 46 changes the image data for the projector 40 to project on the target device 3 according to the calculated score. Preferably, the control unit 46 changes the color of the image data to be projected on the target device 3 according to the total score calculated so that the shooter can easily recognize his or her own training result. it can.

  When the target projected image is a person, such as the projected images of 41 seconds to 60 seconds and 61 seconds to 80 seconds from the start of training in FIG. 7, the data stored in the target wear table 453 is changed according to the landing position. By displaying the injured image using the image and, when the target image is a vehicle, a failed image reflecting the state of wear, a more realistic training can be performed. Furthermore, smoke and explosion hardening caused by impact of a bullet may be displayed at the impact point of the projected image by the projected image of the projector 40.

  According to the shooting training systems of the various embodiments described above, the shooter directly projects the shooting result such as the impact point and the score on the target image as the shooting target, so that the shooting is performed while always looking at the shooting target. Can be. As a result, the next shot can be fired while checking the impact position displayed on the target image. Therefore, even when shooting continuously, it is possible to correct the target while keeping the line of sight fixed to the target each time. Furthermore, by displaying the past shooting result of the shooter individually on the shooting target, it is possible to know his own landing tendency before the start of shooting, and it is possible to perform shooting training with the landing tendency in mind. Furthermore, by using a projection target, training using a movable target image is also possible, and by using a score table for each video frame of the projection target, scoring according to the image of the projection target can be performed. . Still further, shooting training can be performed without using an indicator for a shooter.

  Note that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail for better understanding of the present invention, and are not necessarily limited to those having all the configurations described. For example, the rubber type sensor of the target device is not limited to the rubber type, and may have another configuration as long as it is a sensor capable of projecting a target or a shooting result and capable of detecting a landing position. .

  Furthermore, each of the above-described configurations, functions, control units, and the like has been described mainly with respect to an example of creating a program that realizes some or all of them. However, some or all of them are designed by, for example, an integrated circuit. Needless to say, it may be realized by hardware. That is, all or some of the functions of the processing unit may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array) instead of a program.
