Description

The present invention relates to a shooting evaluation system, and particularly to a score calculation when giving a score according to a landing position on a target in shooting training with live ammunition.

Conventionally, a shooting system for shooting training has been proposed. These shooting systems are configured so that the trainee shoots at the target and scores based on its impact position. The shooting system disclosed in Patent Document 1 is a shooting system using a laser gun, and scores according to the position where a light bullet fired from the laser gun lands on the target plate. At this time, in live shooting, the target plate, the size and shape of the bullet holes differ depending on the competition event, so these are set according to the competition event, and the outer diameters of the bullet holes intersect from the landing position of the light bullet. The area where the points are located is obtained and the points are calculated. In the target device disclosed in Patent Document 2, the coordinate data of the bullet hole position of the hit bullet hitting the target surface is detected by a video camera. At this time, when the bullet holes of the hit bullets hit on the boundary lines having different points and straddle the two areas, the score is given by the higher score. In the shooting training system using live ammunition disclosed in Patent Document 3, the area detection sensor detects the impact in a wider range than the target.

The system of Patent Document 1 is intended for shooting training with a laser gun, and is not intended for shooting training with live ammunition. In Patent Document 2, it is possible to score by the outer diameter of the bullet by detecting the bullet hole of the hit bullet hitting the target surface from the video image, but only the bullet landing on the target surface can be scored. In Patent Document 3, the landing position is detected by an area detection sensor. Specifically, a shock wave detection sensor or an ultrasonic sensor is used to detect a value related to the position coordinate of the passage position of the bullet with respect to the area even if the bullet does not hit the target, and scoring is performed based on this. .. In the prior art, points corresponding to the positions (points) are scored from the coordinates (X, Y) from the sensor that detects the landing position. However, as described in Patent Documents 1 and 2, the scoring range is actually the place where the outer diameter of the bullet reaches. Therefore, when landing at the boundary position of the score, even if the landing passes through the high scoring range if the outer diameter of the bullet hole is, the landing position detected by the sensor passes through the lower scoring range. In that case, the score had to be lower than it should be.

In the present invention, the score is calculated based on the circle of the outer diameter of the bullet (caliber of the firearm) centered on the landing position, not based on the landing position coordinates (X, Y) detected by the area detection sensor. By doing so, it is an object of the present invention to provide a shooting evaluation system capable of calculating a score based on the size of a bullet hole.

The shooting evaluation system of the present invention can communicate with a target device including a target and a detector including a target and a detector for detecting the impact on a detection area set on the same surface as the target. A terminal is provided, and the terminal has a storage unit that stores a scoring table corresponding to a target and a caliber table in which a caliber for each firearm is registered, and a control unit having a scoring processing unit. The scoring processing unit has a caliber. Based on the table, the coordinates of the area of the caliber circle of the firearm used, centered on the landing position coordinates of the impact detected by the detector, are extracted and scored according to the score in the area.

According to the present invention, it is possible to provide a shooting evaluation system capable of calculating a score based on the size of a bullet hole.

Issues, configurations and effects other than those mentioned above will be clarified by the description of the following embodiments.

It is a figure which shows the apparatus configuration of the shooting evaluation system. It is a figure which shows the structure of the target device. It is a figure which shows the structure of the rubber type sensor. It is a block diagram of a terminal. It is a figure which shows the relationship between a target and a detection area. This is an example of a score table. This is an example of a caliber table. It is a flowchart of score calculation. This is an example of landing position coordinates. It is a figure explaining the appearance of a target at a close range. It is a figure which shows the example which changed the target display position.

The device configuration of the shooting evaluation system is shown in FIG. The shooter 1 uses a firearm 2 such as a gun to shoot live ammunition toward a target 4 provided in the target device 3 to carry out training. The landing position is detected by the detector 5 of the target device 3, and by notifying the terminal 7, the landing position is displayed on the display. In addition, training conditions for information during training (targets used, firearms used, etc.) can be set from the terminal 7. The terminal 7 is installed near the shooter 1, and even if there is a distance between the shooter 1 and the target 4, the shooter 1 can check the landing position, the score, and the like in real time. The terminal 7 and the control device 6 of the target device 3 input / output data wirelessly or the like.

The configuration of the target device 3 will be described with reference to FIG. Note that FIG. 2 is a front view of the target device 3 whose side view is shown in FIG. The target device 3 includes a control device 6, a target 4, and a detector 5. The target 4 has a plate-like shape such as a human silhouette, and the control device 6 controls the movement such as standing / falling. 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 which is wider than the target 4, and detects the impact on the detection area 21 regardless of the impact on the target 4. The detection area 21 is an area on the same plane as the target 4, and a wider area 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 the landing coordinates. A plurality of sensors for detecting shock waves, a plurality of ultrasonic sensors, and the like are used to detect the position coordinates of the live bullet, and the detector 5 uses the detection area based on the time when the plurality of sensors detect the shock wave and the positional relationship between the plurality of sensors. The landing coordinates converted into the XY coordinates at 21 are calculated.

However, in the case of a firearm with a slow initial velocity such as a pistol, the impact position cannot be detected by a sensor of the type 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 at the lower part of the wooden frame detect the passage position of the bullet. When the bullet passes through the rubber, the shock wave of the bullet is detected by a plurality of sensors (acoustic sensor, ultrasonic sensor, etc.), and from the time when the plurality of sensors detect the shock wave and the positional relationship between the sensors, in the detection area 35. Calculate the landing coordinates converted to XY coordinates. It is desirable that the rubbers 32 and 33 are self-healing materials having a stretchable ability and capable of shrinking the through hole when the bullet penetrates. As the target in this case, a paper having a shape like the target 4 may be attached on the rubber, or an image may be projected on the rubber.

At the time of impact, the impact position, time, score, etc. are displayed on the terminal 7, and the shooting result can be obtained visually. As for the display, the one disclosed in Patent Document 3 is known. The score is calculated automatically, and the total score can also be displayed. In Patent Document 3, a score corresponding to the coordinates is calculated from the coordinates calculated by the landing position calculation unit.

In this embodiment, it is possible to score according to the outer diameter of the bullet centered on the landing position from the landing coordinates calculated from the detection result of the detector 5 and the caliber size of the firearm. FIG. 4 shows a block diagram of the terminal 7.

The terminal 7 can use a PC (Personal Computer), a dedicated machine, or the like, and has 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 display, a printer, or the like, and displays a control screen of a shooting system or displays information on bullet 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 input from an operator. The transmission / reception unit 44 is an interface for transmitting / receiving data to / from the target device 3. The storage unit 45 is composed of a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disc Drive), a non-volatile memory such as a flash memory, and the like. In addition to the program executed by the control unit 46, data necessary for controlling the target device 3 and analyzing landing is stored. Here, a scoring table 451, a caliber table 452, and a target wear table 453 used for scoring landing are shown. The control unit 46 is composed of a processor such as a CPU (Central Processing Unit) and executes a program stored in the storage unit 45. Here, as a part of the functions executed by the control unit 46, the target setting unit 461, the landing position calculation unit 462, and the scoring processing unit 463 are shown. These are realized by executing the corresponding programs. Details of these will be described later.

The score table 451 stored in the storage unit 45 is created according to the scored target 4 displayed in the detection area 21, and records the score according to the landing point. Score tables are created for each type of target.

It is assumed that the relationship between the detection area 21 and the target 4 is as shown in FIG. 5A. In the example of FIG. 5A, the detection area 21 is 30 mm × 30 mm, and the scored target 4 has different score distributions in three concentric circles centered on the center of the detection area 21, and 5 points and 3 points from the center. It is said to be one point. In addition, 0 points will be given for landings that deviate from that. An example of the score table 451 created based on this is shown in FIG. 5B.

The score table 451 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. From the shape and score of the target 4 used for training, the score at the corresponding position is set for each coordinate of the score table. At this time, if a line (three concentric circles in this case) representing the shape of the target 4 covers a square of 1 mm square even a little, the higher score among the adjacent scores shall be set. Therefore, the thickness of the line (concentric circles in this example) that draws the shape of the target 4 also affects the value in the score table.

FIG. 5C shows an example of a diameter table 452 stored in the storage unit 45. In this way, the caliber of the firearm used in the training is registered in advance.

FIG. 6 shows a flowchart for score calculation. First, the target setting unit 461 selects the target 4 to be used for training and the like. At this time, also input the firearm to be used. Thereby, the scoring table and the caliber of the firearm used for scoring are specified (S61). When the shooting training is started (S62) and the landing notification is received from the target device 3 via the transmission / reception unit 44, the landing position calculation unit 462 calculates the landing position coordinates (S64). The calculation method is as described in relation to FIGS. 2 and 3. FIG. 7 shows an example of the landing position coordinates calculated by the landing position calculation unit. The landing position is the landing point (X coordinate, Y coordinate) detected by the sensor. In this example, it is assumed that there are three landings, and the landing positions 1 to 3 are (3, 5) (19, 11) (23, 19), respectively. Although the case where the landing position coordinates are calculated by the terminal 7 is described here, the landing position coordinates are calculated by the target device 3, and the calculated landing position coordinates are transmitted from the target device 3 to the terminal 7. You may do so.

The scoring unit 463 calculates the score based on the landing position coordinates and the caliber. The coordinates 51 to 53 shown in FIG. 5B are the landing position coordinates of the landings 1 to 3, respectively. In this embodiment, the score is calculated from the bullet holes at the time of impact according to the type of firearm used during the shooting training. Therefore, the coordinates of the circle area of the outer diameter (= caliber of the firearm) of the bullet being used are acquired with the landing coordinate position as the center (S65). For example, if the firearm used is firearm A, the coordinates are included in the circle 54, if the firearm used is firearm B, the coordinates are included in the circle 55, and if the firearm used is firearm C, the coordinates are included in the circle 56. .. Then, all the scores corresponding to the coordinate positions of the circle area are acquired from the score table, the score with the highest score is set as the score, and the score is displayed on the terminal (S66). As a result, if the firearm used is firearm A, the score is 1 point, but if the firearm used is firearm B or firearm C, the score is 3 points. In this way, when scoring with the landing position coordinates, it will be 1 point (the number of points of the landing position coordinates), but by scoring in consideration of the caliber, it is equal to the actual bullet hole (hole through which the bullet passed the target) 3 Since it becomes a point, it is possible to obtain a scoring result that matches the actual score.

Further, in shooting, the appearance of the target 4 from the shooter 1 differs depending on the shooting distance (distance between the shooter 1 and the target 4) and the shooting posture (standing, standing, lying down, etc.). If the shooting distance is short when performing shooting training by sleeping, the target will be looked up as shown in FIG. 8, and the training will be in an unnatural posture. In this case, it is desirable to use the target device 3'with the projection plate 91 to project the target image 92 onto the projection plate 91 so that the target image can be changed only in the height direction. Of course, the area on which the target image 92 is projected needs to be included in the detection area 21. It should be noted that the present invention is not limited to projection, and it is also possible to attach a paper indicating the target.

As shown in FIG. 9, only the height direction of the position where the target image 92 is displayed is changed depending on the shooting conditions (shooting distance, shooting posture). The score table is defined as a coordinate system in the detection area 21. Therefore, when the display position is changed, the score can be calculated according to the changed display position by reflecting the offset value 93 that moves the target position on the target score table. .. Also in this case, the score can be determined by whether or not the bullet hole is in the scoring area by determining the score by the circle with the caliber of the firearm used instead of the score in the landing position coordinates.

By projecting an image of a person, a vehicle, or an object as a target, or by attaching a piece of paper, the effect of landing can be imparted. For example, when the target is displaying a human, by reflecting the human data in the target wear table 453 of the storage unit 45 in the system, it is possible to make a judgment that has the effect of immobilizing the arm, or to make a fatal attack that cannot be counterattacked. It is also possible to determine that a target part has been hit. In the case of a vehicle, it is possible to accurately determine that the engine has been damaged and the vehicle has stopped.

In addition, by inputting data such as bullet and shooting target data, distance, and energy at the time of landing, it is possible to make a more realistic judgment in consideration of damage caused by landing.
