DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shooting training device,
In particular, the present invention relates to a shooting training device using a video target that can shoot live bullets and foster trainees' ability to determine the situation.

[0002]

2. Description of the Related Art There are two types of shooting training: basic shooting training for increasing the accuracy of a live ammunition, and applied shooting training for grasping when and when a shot can be taken. Typically, these shooting exercises fire at targets that are stationary, moving, or obscure,
A trainee or a judge visually recognizes the impact position of the target, and evaluates the hit accuracy and the situation judgment ability.

In order to safely identify the impact position without requiring any manpower, a sound wave caused by an actual bullet is detected by a plurality of acoustic sensors as described in Japanese Patent Application Laid-Open No. 53-121657, and a target is detected from a difference between these detection times. There is a shooting training device that obtains a landing position on a target, or a shooting training device that captures a target with a TV camera and processes images before and after the landing and obtains a landing position from a bullet hole as disclosed in Japanese Patent Application Laid-Open No. 5-196395. Further, as a shooting training apparatus capable of giving a change to a target, there is a slide target apparatus for targeting a projected image on a screen as disclosed in Japanese Patent Application Laid-Open No. 56-119499. In this apparatus, a strip-shaped conductive rubber plate for the X coordinate and a strip-shaped conductive rubber plate for the Y coordinate are overlapped with a gap in a lattice pattern, and a screen for image projection is arranged on the surface thereof. The conductive rubber for the X coordinate and the conductive rubber for the Y coordinate are brought into contact with each other by the impact pressure of the bullet shot toward the vehicle, and the impact coordinates are obtained. The landing position is displayed on the screen by the spot light.

As a shooting training device that shoots bullets and uses a projected image, there are other devices that use a transparent conductive film instead of conductive rubber as disclosed in Japanese Patent Application Laid-Open No. 2-61499, and Japanese Patent Application Laid-Open No. 1-1193600. There is a shooting training device that uses a transmissive target so that an image can be projected from the back side, arranges a transmissive pressure-sensitive resistive element and a photodiode according to a picture, and notifies the landing position by lighting the photodiode. However, each of these uses a slide target utilizing the impact pressure and uses a simulated bullet.

[0005] For applied shooting training for developing situation judgment ability, a shooting training device using a projection target is desirable. However, in the above-mentioned Japanese Patent Application Laid-Open No. 56-119499 using a projection target, first, when a real ammunition is used, a position detection mechanism using a conductive rubber, a conductive film, or a pressure-sensitive resistive element may be destroyed. There is. In fact, Japanese Patent Application Laid-Open No. 1-19360
No. 0 and Japanese Patent Application Laid-Open No. 2-61499 use a simulated ammunition instead of a live ammunition.

Second, the slide target is formed by laminating conductive rubber or conductive film in a grid pattern. For example, when a landing position is detected with an accuracy of 5 mm on a 2400 mm × 1800 mm screen, 480 × 360 = 172, 80
Zero conductive rubber plates must be stuck. This is a difficult task, and a live ammunition can be expensive and expensive, requiring replacement.

Third, in the case of a slide target, the landing position on the screen provided with the landing position detector is merely indicated by spot light or optical die auto, and is not related to each part on the image side. You cannot change the hit score with your head.

[0008]

FIG. 2 shows that the target screen 4 according to the embodiment of the present invention includes the acoustic sensor 15 and the temperature sensor 26.
It is an external view which shows the use condition of the shooting training device which has formed the target body 23 integrally with. The target screen 4 forms a target body integrally with the acoustic sensor 15 and the temperature sensor 26. This target body has a frame 20 that holds the edge of the target screen 4, and an acoustic sensor group including at least three acoustic sensors 15 is provided on each side of the frame 20. Further, a temperature sensor 26 for measuring a temperature near the acoustic sensor 15 is provided at at least one position of the frame 20.

In this embodiment, the size of the screen is as large as 2.4 m × 1.5 m, and the landing detection accuracy is improved by arranging the acoustic sensor group on each side.

Since the target screen 4 directly shoots a live ammunition, a soft rubber having a high elongation is used to minimize damage when the target screen 4 is hit.

Further, the recording / reproducing unit 24 stores a training state image synthesized by superimposition in real time,
This is a device that reproduces the stored video and outputs it to the projection device 3. Next, the operation of the present embodiment will be described. The operation mode of the data processing control unit 6 is switched by the input unit 25.
In the case of the learning mode, the data processing control unit 6 displays a display explaining what the training video of the regenerator 1 is to be projected on the target screen 4 from now on.
After that, the training video is projected on the target screen 4 by instructing the playback device 1 to start playback. After the start of the projection, when the frame of the shooting chance time comes, the data processing control unit 6 projects a display indicating the shooting chance time using the superimpose synthesizing device 2.

Next, the case of the training mode will be described. The data processing control unit 6 divides the target in the training video into two or more parts as shown in FIG. 11, selects one or more parts from the divided parts, and sets the selected part as a hit. In this embodiment, the training image is set to a target hand / foot (P0) other than the target (P0).
1), the target body (P2) and the target head / heart (P3) are divided into four parts, and stored in the storage device 7 as hit / miss data. The shooting instructor or shooting trainee uses the input unit 25 to select a part to be hit from the four parts shown in FIG. 11 and starts projecting the training image on the target screen 4.

Next, as shown in FIG. 2, a live ammunition is shot on the target screen 4 by the shooting trainee. FIG. 3 is an explanatory diagram showing a method of calculating a landing coordinate position on the target screen 4. Here, points S1, S2, and S3 are the mounting positions of the acoustic sensors 15, that is, three acoustic sensors 15 arranged on one side of the target screen 4.
Are shown. In this embodiment, it is assumed that each sensor is arranged on a side parallel to the X coordinate axis.

In this case, as shown in FIG.
The T ₁ time of the detection time to the detection time of the sensor 15b, time T ₂ of the from the detection time of the sensor 15c to detect the time of the sensor 15b, the distance between the distance between the sensors 15a-15b and sensors 15b-15c L, the landing coordinates are P (x, y), the coordinates of the sensor are S ₁ (−L, 0), S

The coordinates can be represented by the following mathematical expressions 1, 2, and 3.

It is assumed that

Equation 4] _{^{L 1 = {2L 2 -C 2}} (T 1 2 + T 2 2)} /

On the relationship between which is disposed in a direction, the calculation accuracy is poor than coordinate x _0. This has been confirmed by experiments, and the error of the coordinate y ₀ is more than twice as bad as the coordinate x ₀ . Therefore, only the coordinate x ₀ among the landing coordinates calculated by the above equation is used, and the coordinate y ₀
For the calculation method, as in the method of calculating the coordinates x _0, the screen of the right or left by using the y-direction of three or more acoustic sensors 15 provided on a straight line in the same manner as described above as Figure 2 The position y ₀ of the y coordinate can be obtained with high accuracy by calculation.

When there are four or more acoustic sensors on a straight line, of the four or more acoustic sensors, the sensor that detects earliest sound generated when a bullet passes through the target screen 4 and its sensor The landing position is calculated by the above formulas 2 and 3 using a total of three acoustic sensors of the two acoustic sensors closest to. In addition, as shown in FIG. 2, when there are acoustic sensor groups in the same axis direction (y direction) on both the right and left sides of the target screen, the calculation is performed based on the calculation result by another sensor group in the axial direction (x direction). Select the sensor group to be used for. That is, if the calculation result of the x coordinate by the x-axis direction acoustic sensor group is on the right side, the calculation in the y direction is performed from the right acoustic sensor group, and if the calculation result of the x coordinate by the x-axis direction acoustic sensor group is on the left side. , The calculation in the y direction is performed from the left acoustic sensor group.

If there are acoustic sensor groups on all four sides of the frame 20, the coordinates are determined by selecting the acoustic sensor groups on the left and right sides based on the acoustic sensor group having the acoustic sensor that detected the earliest sound. calculate. Also, in FIG.
The acoustic sensor 15 is arranged at the intersection of the two sides, and is shared by the acoustic sensor groups on the two sides. Thereby, the acoustic sensor 15
Can be reduced.

When two or more temperature sensors are used, the temperature detected by the temperature sensor closest to each sensor group may be used, or the average of the temperatures detected by each temperature sensor may be used as the actual temperature. Good. As described above, the data processing control section 6 sets the pause state in which the training video of the regenerator 1 is paused immediately after the landing, outputs the mark indicating the landing and the graphic image signal of the information message on the shooting chance time, and superimposes. A graphic image signal is synthesized with the training image stopped by the synthesizing device 2, and the synthesized image can be projected on the target screen.

Next, another operation of the data processing control section 6 will be described. The data processing control unit 6 also determines whether or not the bullet that has landed on the target screen 4 has hit the criminal on the image projected at the time of the landing. here,
FIG. 4 is a flowchart showing the hit / miss determination method. First, the data processing control unit 6 sets the target screen 4
Wait until there is an impact (S1, S2). Then, when there is an impact on the target screen 4, the impact coordinates calculated by the impact coordinate measuring unit 5 are input (S3). Thereafter, an address value in the storage device 7 in which the hit / miss data and the score corresponding to the impact coordinates in the training video projected at the time of impact are stored is calculated (S4). In this storage device 7, each frame of video (there are approximately 30 frames per second), and one frame is finely divided vertically and horizontally, and the hit / miss data and score are divided for each division. It is assumed that it is memorized. As a method for dividing one frame, for example,
There is a method of dividing into 80 and horizontal 512. If all the training video data is not stored in the storage device 7, the frame with the impact is converted into the corresponding frame stored in the storage device 7 (S3 '), and then the address value is changed. Perform calculations.

Thereafter, the data processing control section 6 reads out data on the calculated address value from the storage device 7 (S5). Then, a hit / miss judgment is made based on the selection state of the specific portion input in advance by the input unit 25, the data read from the storage device 7, and the landing position coordinates (S).
6). Here, in the case of a hit (S7), the video is reproduced from the frame in which the hit video is stored (S8). On the other hand, if the video is out of range (S7), the video is reproduced from the frame in which the video is stored (S9). These make it hit one hit /
The departure determination process ends (S10).

Further, the data processing control unit 6 calculates the time from the time when the shooting chance is reached to the time when the shooting is actually performed, scores the time as a shooting response time, and scores the score together with the hit / miss score. Is output to the printing device 8. Also, from the start of training to the end of training, the recording / reproducing unit 24 automatically records a video signal input to the projector 3 under the control of the data processing control unit 6.

There is a method of measuring the shooting reaction time from the difference between the starting frame number of the shooting chance and the frame number where the shot is actually made. If a continuous number is assigned to all the frames of the training image, and the starting frame number of the shooting chance is F0 and the frame number where the shot was actually made is F1, the shooting reaction time Th (second) can be calculated by Expression 5.

[0043]

Th = (F1-F0) / 30 On the other hand, the recording medium 16 storing the data on the training video and the storage device 7 storing the hit / miss score are in principle one-to-one. It corresponds to. When a different training video is created, data on the hit / miss score in the storage device 7 is created and exchanged with the recording medium 16 as a set in correspondence with the video, so that a new training video is created. Shooting training using is possible.

Here, the amount of data stored in the storage device 7 is as follows: (1) Image division per frame is vertically 480
(2) Score data per section is represented by 8 bits, and this score is divided into hit ranges. (3) Score data of hit / miss for 5 seconds per training video (4) Assuming that there are 15 types of training images, 480 dots x 512 dots x 8 bits x 5 seconds x 30 frames x 15 types / 8 bits $ 553
M bytes. Therefore, the storage device 7 can be constituted by a magnetic disk storage device or a magneto-optical disk storage device.

When the number of image divisions, the number of bits of score data, the training video time, or the type of training video is increased in the storage device 7, the amount of data to be stored increases, and the magnetic disk storage device or the magneto-optical disk storage device increases. May not be able to respond. In such a case, the hit / miss judgment is performed only at the shooting chance, and when the impact is detected other than at the shooting chance, the hit mark and the shooting chance are determined without performing the hit / miss judgment. By superimposing the training video with the training video by the superimpose synthesizing device 2 and displaying the superimposition, the data amount can be reduced.

The data amount in the storage device 7 can be further reduced by the following method. A first method is a method in which data on hits / misses recorded in the storage device 7 is not data for each frame but data for every two or more frames. For example, if data on hits / misses is set every two frames, the video will be 30
Since there are frames, the time per two frames is 1 second / 3
0 frames × 2 frames ≒ 66.7 ms.

If the amount of movement of the person in the training video at this time is within one section at the time of image division, the scoring result is the same as when data is set for each frame. Thus, if the target in the training video does not move,
Data of at least one frame may be stored in the storage device 7 during the shooting chance period. In this case, for example, the following method may be used as a method of handling the data of the frame in the storage device 7 with respect to the frame where the impact has occurred.

All training images are numbered with frames,
The frame stored in the storage device 7 is an even frame of the shooting chance period. If the hit frame is an even frame, the address of that frame on the storage device 7 is calculated. If the hit frame is an odd frame, the address of the next even frame on the storage device 7 is calculated. . As a result, the data to be stored in the storage device can be halved, and the storage device 7 having the same storage capacity can store twice as many types of training video hit / miss data.

The second method is a method of reducing the amount of data by limiting the movement of a person in a training video to a certain area. Next, a specific means for switching between the hit video and the video when the video is off shown in FIG. 4 will be described. FIG.
Is an explanatory diagram showing the contents of a training video. FIG. 6 is an explanatory diagram showing the start frame number and the like of each video in the training video.

The contents of the training video shown in FIG. 5 show the breakdown of the training per shooter, and 15 training videos are prepared for each training. FIG. 6 shows the start frame number and the end frame number of the training video recorded on the recording medium 16 reproduced by the reproducer 1. These pieces of information are stored in the storage device 7. First, when the first shooting training is started, the video of the “starting frame No. (m011) of the shooting chance for the first shooting training and the case where the bullet is disconnected (m011)” shown in FIG. 1 is reproduced, and the video is projected on the screen 4. here,
The reason why "the image outside the shooting chance" and "the image when the bullet comes off during the shooting chance" is treated as a series of images is that when changing from outside the shooting chance to during the shooting chance, the image is cut off This is to make the video smoother without any problem. This can be achieved by shooting the training video in uncut.

Thereafter, when the frame number of the reproduced video is "first
Start frame N of shooting chance video for round shooting training

However, in the shooting training device, the training result such as the timing of the impact and the impact position is stored in the data processing control unit 6. Memory 2
7, and does not use a dedicated recording / reproducing device.

In the training mode, the data processing control unit 6
The arithmetic unit 28 stores in the memory 27 the type of the training image, the frame number of the training image having the impact, and the impact position coordinates on the target screen 4 transferred from the impact coordinate measuring unit 5. Then, in the playback mode, the arithmetic unit 28 reads out the stored information from the memory 27 and then causes the playback unit 1 to play back the training video up to the frame where the hit occurs. When the training image reaches the frame where the landing is made, the arithmetic unit 28 projects the landing mark from the landing position coordinates stored in the memory 27 onto the target screen 4 via the superimposition synthesizing device 2. I do. At the same time, the shooting reaction time is calculated from the starting frame number of the shooting chance time stored in the storage device 7 and the number of the frame having the impact read out from the memory 27, and the calculation result is determined to be during the shooting chance time. The message is projected onto the target screen 4 via the superimpose synthesizing device 2 together with a message indicating the above. After that, as in the training mode, the hit /
A hit / off hit is determined from the hit data and the setting conditions of the specific portion, and a training video to be played by the playback device 1 is selected and played.

As a result, the present training apparatus does not require a recording / reproducing device, and can easily reproduce the training at any time. FIG. 10 is a block diagram showing a shooting training device according to a fifth embodiment of the present invention. In the above-described first to fourth embodiments, an image actually shot by a video camera or the like is used as a training image.
