Description

The present disclosure relates to a targeting system and a program, and particularly relates to a targeting system and a program that can increase the visibility of impact marks.

Conventionally, a soft air gun, which is a toy gun equipped with a mechanism that fires a plastic bullet (hereinafter referred to as a BB (Ball Bullet) bullet) using low-pressure compressed air, is used to shoot at a target, and the BB bullet is fired at the target. Shooting competitions are held in which players compete for scores based on the position of bullets when they land. In such shooting competitions, it is important to accurately detect the impact position of the BB bullet.

Therefore, the applicant has developed a target that can accurately calculate the impact position, velocity, energy, etc. of a BB bullet that has landed on a target plate by detecting the shock wave that is generated when a BB bullet hits the target plate. system has been proposed (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2014-25677

By the way, in general, in soft air guns, the gun barrel and the sight are fixed approximately parallel, so depending on the target distance, the difference (parallax) between the axis of the gun barrel and the optical axis of the sight, An error will occur between the targeted position and the impact position. In addition, since BB bullets fired from soft air guns fly in a parabola, the amount of BB bullets falling varies depending on the target distance, resulting in an error between the aimed position and the impact position. I will do it. Therefore, when shooting at a target distance, the sight must be adjusted according to the distance to avoid errors caused by parallax or falling BB bullets (hereinafter referred to as aiming error). There is a need to. Therefore, for example, if a soft air gun whose sight has been adjusted to prevent aiming errors at a distance of 15 to 20 meters outdoors is used indoors at a distance of about 5 meters, the sight must be readjusted. It had become.

In this way, conventionally, in order to accommodate aiming errors, it is necessary to adjust the sight depending on the target distance, and it is not possible to easily use a soft air gun that has been sighted at a given distance at a different distance. I couldn't.

<First configuration example of target device according to embodiment of the present invention>
FIG. 1 is a perspective view showing a first configuration example of a target device according to an embodiment of the present invention.

This targeting device 11 includes a mechanism for displaying a target for shooting using a soft air gun, a recovery mechanism for recovering BB bullets 12 fired at the target device 11, and a point of impact and impact speed when the BB bullets 12 land. It has a function to output a detection signal for detecting such things.

The one-dot chain arrow in FIG. 1 indicates an example of the path of the fired BB bullet 12, and the side where the BB bullet 12 is heading toward the target device 11 (lower right side in FIG. 1) is the target device. The front side of the target device 11 is the front side of the target device 11, and the opposite side (upper left side in FIG. 1) is the back side of the target device 11.

The back side of the target device 11 is equipped with a display 30 made of an LCD (liquid crystal display) or the like that displays an image representing a target (hereinafter referred to as a target image). The BB bullet 12 fired at the target image visible at the back of the target device 11 hits the transparent target plate 24 provided on the front side of the display 30 and is reflected or rolled inside the target device 11. Thereafter, the target device 11 is collected into a collection case 13 located on the left side when viewed from the front side.

As illustrated, the target device 11 includes a housing 21, a front plate 22, a back plate 23, a target plate 24, a collection plate 25, an outlet nozzle 26, acoustic sensors 27-1 to 27-4, and a signal processing board 28. , and a display 30.

The housing 21 has upper and lower surfaces and left and right side surfaces formed by assembling a top plate 21a, a right side plate 21b, a left side plate 21c, and a bottom plate 21d, and has a rectangular cylindrical shape with an open front and back sides. The top plate 21a is a plate-shaped member that forms the upper surface of the housing 21, and the right side plate 21b is a plate-shaped member that forms the right side of the housing 21. Further, the left side plate 21c is a plate-shaped member that constitutes the left side surface of the casing 21, and the lower surface plate 21d is a plate-shaped member that constitutes the lower side of the casing 21.

The front plate 22 is a plate-shaped member attached to the housing 21 so as to cover the vicinity of the lower side of the front opening of the housing 21.

The back plate 23 is a transparent plate-shaped member attached to the housing 21 so as to cover the entire rear opening of the housing 21.

The target board 24 is made of a plate-like member that allows the target image displayed on the display 30 to pass through and can receive the impact of the BB bullet 12 fired toward the target image by a soft air gun, and is generally flat. The upper and lower ends and the left and right ends are fixed to the inner surface of the casing 21 from the front side so that the casing 21 does not bend. For example, the target plate 24 is made of a material (specifically, a soft vinyl chloride resin with a thickness of 2.0 mm) that has a predetermined plasticity against impact (a material that has a slow recovery speed). By using a member made of such a material, when the BB bullet 12 lands on the target plate 24, it slowly restores its original shape, so it is possible to prevent the occurrence of ricochet that would reach the outside of the target device 11. can. Further, as described above, since the target plate 24 is attached from the front side, the target plate 24 can be easily replaced without removing the display 30 and the back plate 23.

By configuring the back plate 23 and the target plate 24 with transparent members, the user can visually recognize the target image displayed on the display 30 from the front side of the target device 11.

The collection plate 25 is a space inside the housing 21 on the front side of the target plate 24 and below the lower end of the front opening of the housing 21 (the upper end surface of the front plate 22). It is arranged in a space and is fixed so as to have an overall slope downward toward the rear side and downward toward the left side.

The discharge port nozzle 26 is attached to the outer surface of the left side plate 21c so as to cover the BB bullet discharge port formed on the left side plate 21c of the housing 21, and guides the BB bullets 12 exiting from the discharge port to the recovery case 13. .

The acoustic sensors 27-1 to 27-4, for example, acquire the impact sound generated when the BB bullet 12 lands on the target plate 24, and transmit an acoustic signal according to a change in the amplitude of the acquired impact sound to the signal processing board 28. supply to.

The acoustic sensors 27-1 to 27-4 are fixed inside the housing 21 on the back side of the target plate 24, close to the four corners of the target plate 24, respectively. For example, the acoustic sensor 27-1 is arranged near the upper end of the inward facing surface of the left side plate 21c, and the acoustic sensor 27-2 is arranged near the upper end of the inward facing surface of the right side plate 21b. Further, the acoustic sensor 27-3 is arranged near the lower end of the inward facing surface of the left side plate 21c, and the acoustic sensor 27-4 is arranged near the lower end of the inward facing surface of the right side plate 21b. Hereinafter, the acoustic sensors 27-1 to 27-4 will be collectively referred to as the acoustic sensor 27. Although the present embodiment has described a configuration using four acoustic sensors 27-1 to 27-4, the number of acoustic sensors 27 is not limited to four. For example, depending on the size or shape of the target device 11, a number of acoustic sensors 27 such as three, six, or eight that can appropriately measure the landing position and the like can be used.

The space in which the acoustic sensor 27 is arranged is closed on the front side by the target plate 24 , closed on the top and bottom and left and right sides by the casing 21 , and closed on the back side by the back plate 23 . That is, the acoustic sensor 27 is arranged in a closed space 29 that is closed from the outside by the housing 21, the back plate 23, and the target plate 24.

Here, the closed space 29 is not a completely sealed space, but has a structure in which an opening is appropriately provided. In this way, by configuring the closed space 29 to be partially opened by the opening, it is not completely open, and unlike a completely closed space, it is possible to properly reduce impact noise. The pressure rise is moderately suppressed while allowing the sound to resonate. Therefore, in the targeting device 11, since air can easily enter and exit the substantially closed closed space 29 through the opening, for example, the closed space due to the BB bullet 12 colliding with the target plate 24 The increase in pressure inside the tube 29 is appropriately suppressed.

As a result, even if the volume of the closed space 29 suddenly decreases due to, for example, the target plate 24 being deflected by the impact of the BB bullet 12, the air can be appropriately discharged through the opening, allowing the BB bullet 12 to It is possible to appropriately suppress the increase in pressure within the closed space 29 when the bullet lands. Therefore, the acoustic sensor 27 can stably acquire the impact sound. Therefore, in the target device 11, variations in the impact position and impact speed determined based on the acoustic signal output from the acoustic sensor 27 are suppressed, and as a result, the detection accuracy of the impact position and impact speed can be improved.

The signal processing board 28 is arranged in the space between the bottom plate 21d and the collection plate 25. The signal processing board 28 performs predetermined signal processing on the acoustic signal output from the acoustic sensor 27 when the BB bullet 12 lands on the target plate 24, so that the BB bullet 12 lands on the target plate 24. It outputs a detection signal to detect the point of impact and speed of impact when the bullet hits the target.

In the predetermined signal processing by the signal processing board 28, the acoustic signal is amplified and full-wave rectified, and a peak hold signal holding the peak value of the amplitude and a signal obtained by integrating the peak hold signal are equal to or higher than a reference value. An impact sound detection time signal indicating the timing at which this occurs is output as a detection signal. This detection signal is supplied to the PC 15 in FIG. 2, which will be described later.

In the target device 11 configured as described above, the fired BB bullet 12 lands on the target plate 24, and the area of the target plate 24 is shaped into an extremely shallow cone shape around the impact point according to the impact force. The impact caused by the collision of the BB bullet 12 is absorbed by the recess. The BB bullet 12, whose landing impact has been absorbed by the target plate 24, falls toward the collection plate 25, and rolls toward the back side and left side within the target device 11 according to the inclination of the collection plate 25. After that, it is discharged from the discharge port of the left side plate 21c, passes through the discharge port nozzle 26, and is collected in the collection case 13.

In this way, the target device 11 is configured such that the target plate 24 can absorb the impact of the BB bullets 12 and the BB bullets 12 fall toward the collection plate 25. The BB bullet 12 can be reliably and easily recovered without causing ricochet extending to the outside.

Further, the acoustic sensor 27 of the target device 11 is arranged in a closed space 29 where the acoustic environment is constant. Therefore, the acoustic sensor 27 can acquire impact sounds with higher reproducibility. In other words, the acoustic sensor 27 can acquire substantially the same impact sound if the impact point and impact speed of the BB bullet 12 are the same.

That is, the target device 11 has a configuration in which the rear opening with respect to the closed space 29 is covered by the back plate 23 and the front opening with respect to the closed space 29 is covered with the target plate 24. As a result, in the target device 11, like a musical instrument (for example, a drum or timpani) that produces sound by the vibration of a membrane stretched over the opening, the target device 11 can generate a reproducible impact by the vibration when the BB bullet 12 collides with the target plate 24. A sound is generated.

Therefore, for example, when the BB bullet 12 lands on a predetermined location on the target plate 24, the acoustic sensor 27 always produces the same impact sound under the same landing conditions (landing position, landing speed, and bullet weight). be obtained. Thereby, based on the acoustic signal output from the acoustic sensor 27, the impact point, which is the position on the target plate 24 where the BB bullet 12 landed, and the impact point, which is the velocity of the BB bullet 12 when it landed on the target plate 24, are determined. The bullet speed and the energy of the BB bullet 12 when it hits the target plate 24 can be detected with high accuracy.

Furthermore, by arranging the acoustic sensor 27 in the closed space 29, it is possible to prevent the acoustic sensor 27 from acquiring the firing sound when the BB bullet 12 is fired from the soft air gun, for example. This eliminates the need for processing to remove the emitted sound component from the acoustic signal output from the acoustic sensor 27, so that the impact point of the BB bullet 12, etc. can be calculated that much more quickly. In addition, the accuracy of calculations such as the point of impact can be improved.

<Target system configuration example>

Next, a configuration example of a target system using the target device 11 will be described with reference to FIG. 2.

As shown in FIG. 2, the target system 14 includes a target device 11 and a PC (Personal Computer) 15.

The user installs the PC 15 at hand, connects the signal processing board 28 of the target device 11 and the PC 15 with the signal cable 16, and connects the display 30 and the PC 15 with the video cable 17. Note that, for example, the target device 11 and the PC 15, and the display 30 and the PC 15 may be configured to be connected by wireless communication.

The user then operates the PC 15 to display an operation screen (for example, FIG. 3, which will be described later) on the display section of the PC 15, and display a target image (for example, FIGS. 9 to 13, which will be described later) on the display 30. Thereafter, the user points the barrel 18 of the soft air gun at the target device 11, looks into the sight 19 movably fixed along the barrel 18, and aims at the target image displayed on the display 30. You can shoot at the same time.

Here, as described above, depending on the parallax between the axis of the gun barrel 18 and the optical axis of the sight 19, the falling amount of the BB bullet which varies depending on the distance, etc., the position aimed by the sight 19 and the BB bullet 12 An aiming error will occur in the position where the bullet lands. For example, even if you use a soft air gun with a sight adjusted to 20 to 30 meters to aim at the target device 11 set at a distance of about 5 meters, you will not be able to make the BB bullet 12 land at the targeted location. .

Therefore, the targeting system 14 has a sight that corrects the display position of the impact mark displayed on the target panel 51 with respect to the impact position determined based on the detection signal detected when the BB bullet 12 hits the target plate 24. Correction processing can be performed. As a result, the targeting system 14 can easily reach the target position of the target device 11 installed at a distance of about 5 m without adjusting the sight 19 using a soft air gun with a sight adjusted to 20 to 30 m. A bullet impact mark can be displayed.

Furthermore, the targeting system 14 performs a landing delay process that delays the time from the detection timing when it is detected that the BB bullet 12 has landed on the target board 24 to the display timing when the landing mark corresponding to the landing position is displayed. I can do it. Thus, for example, when the targeting device 11 is installed at a distance of about 5 m, the targeting system 14 delays the display of the impact mark by the time the BB bullet 12 flies from 15 to 25 m, so that when the BB bullet 12 It is possible to give the user the same feeling as when a bullet lands after flying ~30m.

Settings for such aiming correction processing and impact delay processing can be performed using an operation screen displayed on the display section of the PC 15.

Next, FIG. 3 is a diagram showing an example of an operation screen displayed on the display section of the PC 15.

The operation screen 50 shown in FIG. 3 includes a target panel 51, a score panel 52, a bullet velocity meter panel 53, a command panel 54, a scoreboard 55, an aiming correction setting operation section 56, an X direction correction amount input section 57, a Y direction correction An amount input section 58, a landing delay setting operation section 59, and a delay amount input section 60 are displayed.

A selected target image is displayed on the target panel 51 when a shooting competition is held using the target system 14, and in the example of FIG. 3, a standard target is displayed. Further, on the target panel 51, a landing mark is displayed according to the landing position determined based on the detection signal detected when the BB bullet 12 lands on the target plate 24, and in the example of FIG. 3, the landing mark is Displayed in 5 locations.

The score panel 52 displays a score corresponding to a shooting competition using the target image displayed on the target panel 51. For example, in the example shown in FIG. 3, the number of times the BB bullet 12 has been detected, the number of times the BB bullet 12 has landed on the target, the score according to the impact position of the BB bullet 12, the total score, and the time remaining are displayed. ing.

The bullet velocity meter panel 53 displays the energy and bullet velocity when the BB bullet 12 hits the target plate 24. Further, the bullet velocity meter panel 53 displays the number of cycles, which is the number of times the BB bullet 12 has been detected to land in one second, and the bullet diameter and bullet weight input in advance.

The command panel 54 is used to input various setting items corresponding to a shooting competition using a target image displayed on the target panel 51.

The scoreboard 55 displays the score, the direction from the center toward the impact position, the time when the impact was detected, the energy, and the bullet speed each time the impact of the BB bullet 12 is detected.

The aim correction setting operation section 56 is operated when setting whether to enable or disable the aim correction process for correcting the display position of the impact mark according to the amount of correction. For example, the aim correction setting operation section 56 is a GUI of check boxes, and a check mark is displayed when an operation to enable aim correction processing is performed, and a check mark is displayed when an operation to disable aim correction processing is performed. It will be hidden.

The X-direction correction amount input section 57 and the Y-direction correction amount input section 58 input the X-axis direction used in the aiming correction processing when an operation to enable the aiming correction processing is performed on the aiming correction setting operation section 56. and a correction amount in the Y-axis direction. For example, the X-direction correction amount input section 57 and the Y-direction correction amount input section 58 are GUIs of text input boxes, and numerical values can be directly input using the keyboard of the PC 15 or the up and down buttons can be operated. By doing so, it is possible to input the correction amounts in the X-axis direction and the Y-axis direction, respectively.

The impact delay setting operation section 59 is operated to enable or disable the impact delay process that delays the display of the impact mark according to the amount of delay. For example, the impact delay setting operation section 59 is a GUI with checkboxes, and when an operation to enable impact delay processing is performed, a check mark is displayed, and when an operation to disable aiming correction processing is performed, a check mark is displayed. It will be hidden.

When the landing delay setting operation section 59 is operated to enable the landing delay processing, the delay amount used in the landing delay processing is input to the delay amount input section 60 . For example, the delay amount input section 60 is a GUI of a text input box, and the delay amount can be input by directly inputting numerical values using the keyboard of the PC 15 or by operating the up and down buttons. can. For example, the user determines the timing of impact during an actual competition based on the difference between the distance to the target during the actual competition and the distance to the target device 11 when using the targeting system 14. The delay amounts are determined so that they match and are input to the delay amount input section 60.

Such an operation screen 50 is displayed on the display section of the PC 15, and the user can enable or disable the aiming correction process, enable or disable the impact delay process, and input the correction amount and delay amount. can.

For example, the user can measure the distance between the centers of the gun barrel 18 and the sight 19, and input the measured value to the Y-direction correction amount input section 58 as the correction amount for the sight correction process. As a result, when the target device 11 is at a close distance (for example, about 1 m), the distance between the centers of the gun barrel 18 and the sight 19 appears as an aiming error, so the aiming error is corrected. The impact position can be displayed to match the target position.

Further, in the targeting system 14, in addition to inputting the correction amount used in the aiming correction process using the X direction correction amount input section 57 and the Y direction correction amount input section 58, for example, grouping (i.e. , can be input using the grouping function that measures bullet collection performance from multiple bullet impact marks).

With reference to FIG. 4, inputting a correction amount using the grouping function will be described.

FIG. 4A is a diagram illustrating a grouping function when a grouping center is set as a midpoint between the most distant landing marks among a plurality of landing marks to be grouped. FIG. 4B is a diagram illustrating a grouping function when the average position determined from a plurality of impact marks to be grouped is set as a grouping center.

In addition, in FIG. 4, the left side shows the target image and the impact mark displayed on the target panel 51, and the right side shows the grouping that is superimposed and displayed on the operation screen 50 when the grouping function is executed. A settings screen 61 is shown.

For example, when the grouping function is executed, a grouping center 62 and a grouping circle 63 are displayed on the target image. The grouping center 62 is determined from the intermediate position (between bullet holes) between the most distant impact marks among the plurality of impact marks to be grouped, as shown in FIG. 4A, or from the plurality of impact marks to be grouped, as shown in FIG. 4B. You can select either one. The grouping circle 63 is a circle whose diameter is a straight line connecting the most distant landing marks among the plurality of landing marks to be grouped.

For example, a grouping center 62 that is measured by grouping a predetermined number (12 in the example of FIG. 4) of detected bullet impact positions by repeatedly shooting a predetermined number of shots aiming at the center of the target. The difference (deviation) can be used as a correction value used in the aiming correction process. In particular, when the average position (FIG. 4B) determined from a plurality of grouped impact marks is selected as the grouping center 62, aiming errors can be corrected more accurately by repeating grouping to obtain such correction values. can do.

Furthermore, in the target system 14, it is possible to specify which of the intermediate position and the average position to use as the grouping center 62 using the grouping setting screen 61. Furthermore, using the grouping setting screen 61, it is possible to specify whether to display or hide the grouping circle 63, the color in which the grouping circle 63 is displayed, and the number of target bullets, which is the number of impact marks to be grouped.

Furthermore, the grouping setting screen 61 displays the diameter of the grouping circle 63 and the deviation value representing the amount of deviation from the center of the target to the grouping center 62 in the X direction and the Y direction. Then, when the apply button for aiming correction on the grouping setting screen 61 is operated, the inverse of this deviation value (a value that becomes 0 when added to the amount of deviation from the center) is used in the aiming correction process. It can be applied to the correction amount in the axial direction and the Y-axis direction. That is, the inverse of the deviation value displayed on the grouping setting screen 61 is input to the X-direction correction amount input section 57 and the Y-direction correction amount input section 58 in FIG. In this way, the deviation value is displayed on the grouping setting screen 61, and the inverse of the deviation value is displayed on the X-direction correction amount input section 57 and the Y-direction correction amount input section 58. is presented, the user can recognize the amount of deviation.

In this manner, the targeting system 14 uses the grouping function to aim at the center of the target, detects the impact of a plurality of BB bullets 12, and determines the grouping center 62 of their impact positions. Then, the inverse of the value of the deviation of the grouping center 62 from the center of the target in the X-axis direction and the Y-axis direction can be applied to the correction amount used in the aiming correction process. As a result, when a bullet lands on the grouping center 62, the landing position is corrected so that the deviation becomes zero.

Therefore, for example, the user can shoot several shots at the center of the target, group them based on their impact marks, and simply operate the Apply to Aiming Correction button on the grouping setting screen 61 to determine the amount of correction. The impact position can be corrected by aiming correction processing that applies the following. For example, when adjusting the sight 19 by grouping, the effect of the adjustment can be tested in advance before actually moving the sight 19.

In addition, when the aiming correction process is enabled in the aiming correction setting operation section 56 of the operation screen 50, when the apply button for aiming correction on the grouping setting screen 61 is operated, the distance between the grouping center 62 and the center of the target is The deviation is not used as it is as the correction amount, but is corrected to a value with the deviation added to the correction amount. Therefore, in this case, if you perform grouping aiming at the center of the target and operate the apply to aiming correction button on the grouping setting screen 61, the correction amount can be further corrected, so by repeating the same procedure, Very accurate aiming correction processing can be performed.

In this case, it is more effective if the average position is selected as the grouping center 62 because the position of the grouping center converges to the target center by repeating the above procedure. Further, for example, a function may be provided that automatically operates an application button for aiming correction every time a certain number of bullets land. This makes it possible to make extremely accurate aiming corrections by simply repeating the basic practice of aiming at the center of the target and shooting. Furthermore, for example, after shooting a larger number of bullets (for example, 100 shots), the button for applying aiming correction may be operated only once, and in this case as well, very accurate aiming can be achieved. Corrections can be made.

Furthermore, for example, when the number of clicks (turning angle) when adjusting the sight of the sight 19 can be calculated from the deviation value as in a scope like the sight 19, the sight adjustment of the sight 19 can be calculated from the deviation value. , by calculating and moving based on the inverse of the deviation values in the X and Y directions displayed on the grouping setting screen 61 (values that make the difference between the grouping center 62 and the center of the target 0), accurately at once. It can be carried out. In other words, the targeting system 14 has the advantage that the user can use it when adjusting the aim of the sighting device 19 just by displaying such a deviation. In addition to displaying the deviation using numerical values as shown in Figure 4, for example, the number of clicks required to aim should be calculated and presented, or the deviation may be presented to the user using audio or the like. Good too. Further, in addition to displaying both the deviation in the X direction and the deviation in the Y direction, only one of them may be displayed.

<Configuration example of impact detection display processing section>

FIG. 5 is a block diagram showing an example of the functional configuration of the impact detection display processing section.

As shown in FIG. 5, the impact detection display processing unit 71 includes a impact position detection unit 72, a impact mark display unit 73, a correction amount calculation unit 74, a correction amount acquisition unit 75, and a setting application unit 76. .

A detection signal output from the signal processing board 28 of the target device 11 is supplied to the impact position detection section 72 . Then, the impact position detection section 72 detects the impact position at which the BB bullet 12 hits the target plate 24 based on the detection signal, and supplies the impact position to the impact mark display section 73.

The impact mark display section 73 displays the impact mark on the display 30 at a display position based on the impact position detected by the impact position detection section 72 . At this time, if the aiming correction process is set to be valid, the landing mark display section 73 displays the landing mark at the display position where the landing position has been corrected according to the correction amount. On the other hand, when the aiming correction process is set to be disabled, the impact mark display section 73 displays the impact mark at a display position that matches the impact position.

Similarly, when the impact delay process is set to be valid, the impact mark display section 73 displays a display timing that is delayed according to the amount of delay from the detection timing when the impact of the BB bullet 12 on the target plate 24 is detected. Display the impact mark. On the other hand, when the impact delay process is set to be disabled, the impact mark display section 73 displays the impact mark in the shortest processing time, for example, without delaying the display timing from the detection timing.

As described with reference to FIG. 4, the correction amount calculation unit 74 performs a process of calculating the correction amount when inputting the correction amount using the grouping function. For example, the correction amount calculation unit 74 can be realized using one function of the grouping function, that is, the function of determining the grouping center 62.

The correction amount acquisition unit 75 acquires the correction amount calculated by the correction amount calculation unit 74 or the correction amount input using the X-direction correction amount input unit 57 and the Y-direction correction amount input unit 58 in FIG. Then, the acquired correction amount is supplied to the setting application section 76. Further, the correction amount acquisition section 75 acquires the input delay amount using the delay amount input section 60 and supplies the acquired delay amount to the setting application section 76 .

The setting application section 76 sets whether or not the aiming correction process is enabled or disabled in the impact mark display section 73 according to the user's operation on the aiming correction setting operation section 56 . Then, when setting the aiming correction process to be effective for the landing mark display section 73, the setting application section 76 supplies the correction amount acquired by the correction amount acquisition section 75 to the landing mark display section 73. Similarly, the setting application section 76 sets the impact mark display section 73 to enable or disable the impact delay process according to the user's operation on the impact delay setting operation section 59 . Then, when setting the impact delay processing to be effective for the impact mark display unit 73, the setting application unit 76 supplies the impact delay amount acquired by the correction amount acquisition unit 75 to the impact mark display unit 73.

The impact detection display processing unit 71 is configured as described above, and the impact mark display unit 73 enables or disables the aiming correction process to display the impact mark, or performs the impact delay process according to the settings made by the setting application unit 76. You can enable or disable it to display impact marks.

<Processing executed by the impact detection display processing unit>

Next, with reference to FIGS. 6 to 8, the processing executed in the impact detection display processing section 71 will be described.

FIG. 6 is a flowchart illustrating the impact detection display process.

For example, when the detection signal output from the signal processing board 28 of the target device 11 is supplied to the impact position detection unit 72, the process is started, and in step S11, the impact position detection unit 72 detects the BB The impact position where the bullet 12 hits the target plate 24 is calculated. Then, the landing position detection section 72 supplies the calculated landing position to the landing mark display section 73.

In step S12, the impact mark display section 73 determines whether the aiming correction process is set to be enabled or disabled, and if it is determined that the aiming correction process is set to be enabled, the process proceeds to step S13. .

In step S13, the landing mark display section 73 displays a message when the aiming correction process is enabled (for example, step S33 in FIG. 8, which will be described later) for the landing position supplied from the landing position detection section 72 in step S11. The display position to which the correction amount supplied from the setting application unit 76 is applied is calculated.

In step S14, the impact mark display unit 73 determines whether the impact delay process is set to be enabled or disabled, and if it is determined that the impact delay process is set to be enabled, the process proceeds to step S15. .

In step S15, the impact mark display unit 73 waits until the display timing according to the delay amount supplied from the setting application unit 76 when the impact delay process is enabled (for example, step S37 in FIG. 8, which will be described later). , when the display timing comes, the process proceeds to step S16.

On the other hand, if it is determined in step S12 that the aim correction process is set to be disabled, or if it is determined in step S14 that the impact delay process is set to be disabled, the process proceeds to step S16.

In step S16, the landing mark display section 73 displays the landing mark at a display position based on the landing position detected by the landing position detection section 72. At this time, if the display position has been calculated in step S13, the landing mark display section 73 displays the landing mark at the display position. After the process of step S16, the impact detection display process is ended.

FIG. 7 is a flowchart illustrating correction amount calculation processing using the grouping function.

For example, when the user operates the PC 15 in FIG. 2 to execute the grouping function, the process starts, and in step S21, the correction amount calculation unit 74 displays the grouping setting screen 61 as shown in FIG. 4 on the PC 15. section.

In step S22, the correction amount calculation unit 74 determines whether the grouping center 62 is set at the average position or between the bullet holes, according to the settings on the grouping setting screen 61.

If the correction amount calculation unit 74 determines in step S22 that the grouping center 62 is set at the average position, the process proceeds to step S23. In step S23, the correction amount calculation unit 74 calculates, as the grouping center 62, the average position determined from the impact marks of the target number of bullets to be grouped.

On the other hand, if the correction amount calculation unit 74 determines in step S22 that the grouping center 62 is set between bullet holes, the process proceeds to step S24. In step S24, the correction amount calculating unit 74 calculates, as the grouping center 62, the intermediate position between the most distant landing marks of the target number of bullets to be grouped.

After the process in step S23 or S24, the process proceeds to step S25, where the correction amount calculation unit 74 determines whether or not to apply the grouping center 62 calculated in step S23 or S24 to the correction amount used in the aiming correction process. . For example, when the apply button for aiming correction displayed on the grouping setting screen 61 in FIG. 4 is operated, the correction amount calculation unit 74 determines to apply the grouping center 62 to the correction amount.

In step S25, if the correction amount calculation unit 74 determines that the grouping center 62 is to be applied to the correction amount, the process proceeds to step S26, and the correction amount calculation unit 74 calculates the grouping center 62 calculated in step S23 or S24. The reciprocal of the obtained deviation value is supplied to the correction amount acquisition unit 75 as the correction amount used in the aiming correction process.

After the process in step S26 or if it is determined in step S25 that the grouping center 62 is not applied to the correction amount, the correction amount calculation process is ended.

FIG. 8 is a flowchart illustrating the aiming correction and impact delay setting application processing.

For example, the process starts when the operation screen 50 in FIG. or disabled.

In step S31, if the setting application unit 76 determines that the aiming correction process is set to be valid, the process proceeds to step S32. In step S32, the setting application unit 76 acquires the correction amount from the correction amount acquisition unit 75. For example, the correction amount acquisition section 75 uses the inverse number of the deviation value obtained as the grouping center 62 supplied in step S26 of FIG. 7 described above, or the correction amount input section 57 of FIG. The value input to the amount input section 58 is supplied to the setting application section 76 as a correction amount.

In step S33, the setting application unit 76 supplies the correction amount acquired in step S32 to the impact mark display unit 73, and sets the impact mark display unit 73 so that the aiming correction process is effective.

On the other hand, if the setting application unit 76 determines in step S31 that the aiming correction process is set to be disabled, the process proceeds to step S34. In step S34, the setting application unit 76 sets the impact mark display unit 73 so that the aiming correction process is disabled.

After the processing in step S33 or S34, the process proceeds to step S35, where the setting application unit 76 determines whether the impact delay processing is set to be enabled or disabled, according to the user's operation on the impact delay setting operation unit 59. .

In step S35, if the setting application unit 76 determines that the impact delay process is set to be valid, the process proceeds to step S36. In step S36, the setting application unit 76 acquires the delay amount from the correction amount acquisition unit 75. For example, the correction amount acquisition section 75 supplies the value input to the delay amount input section 60 in FIG. 3 to the setting application section 76 as the delay amount.

In step S37, the setting application unit 76 supplies the delay amount acquired in step S36 to the impact mark display unit 73, and sets the impact delay process to be effective for the impact mark display unit 73.

On the other hand, if the setting application unit 76 determines in step S35 that the impact delay process is set to be disabled, the process proceeds to step S38. In step S38, the setting application unit 76 sets the impact mark display unit 73 so that the impact delay process is disabled.

After the processing in step S37 or S38, the aiming correction and impact delay setting application processing is completed.

<Display example of target image>

Next, the target image displayed on the display 30 in FIG. 1 will be described with reference to FIGS. 9 to 13.

FIG. 9 shows an example of a target image displayed on the display 30 when a shooting competition using five targets is held using the target system 14. For example, the display 30 displays a target panel 51, a score panel 52, and a bullet meter panel 53, similar to the operation screen 50 in FIG.

Five targets T1 to T5 are displayed on the target panel 51 in different sizes and positions. Furthermore, on the target panel 51, any image can be selected and displayed in the background of the targets T1 to T5, and in the example of FIG. The image you created is displayed.

Further, the size and arrangement position of the targets T1 to T5 can be set according to the distance in the depth direction of the arrangement of the targets in an actual shooting competition. For example, in an actual shooting competition, a target that is placed toward the front is displayed as having a large size and is placed at the bottom, while a target that is placed toward the back in an actual shooting competition is displayed with a large size and is placed at the bottom. It is small and displayed with its placement position on the upper side.

Further, in this shooting competition, a stop target to be shot at last among targets T1 to T5 is specified, and in the example of FIG. 9, target T5 is specified as the stop target.

Then, when the start button on the command panel is pressed or when the first impact on the target plate 24 is detected, the timer starts, and when the impact on the target T5 is detected, the timer stops and the lower part of FIG. As shown, the time measured by the timer is displayed. However, if one of the targets T1 to T4 is missed and target T5, which is a stop target, is shot, a penalty of 3 seconds is added for each missed target.

Furthermore, in the target system 14, the sizes of the targets T1 to T5 displayed on the target panel 51 can be set arbitrarily. For example, the target displayed on the target panel 51 is based on the distance from the user to the target in an actual shooting competition and the distance from the user to the target device 11 when shooting using the targeting system 14. Set the sizes of T1 to T5. In other words, when the distance from the user to the target device 11 when shooting using the target system 14 is 1/6 of the distance from the user to the target in an actual shooting competition, the display is displayed on the target panel 51. The size of the targets T1 to T5 to be displayed is set to 1/6 of the actual target.

As a result, the size of the targets T1 to T5 displayed on the target panel 51 when viewed by the user can be made approximately the same size as the size when the user views the targets in an actual shooting competition. . Therefore, the user can perform more realistic practice using the target system 14.

At this time, if you use a soft air gun whose aim is adjusted based on the distance in an actual shooting competition and aim at the target device 11 at a distance of 1/6, the size of the target will be approximately the same. No matter how big it seems, if you make an aiming error, you won't be able to practice effectively. At this time, in the targeting system 14, by setting the above-mentioned aiming correction processing to be effective and using a correction amount according to the distance to the targeting device 11, the actual landing position has an aiming error. However, the impact mark can be displayed to eliminate the aiming error. Therefore, the targeting system 14 allows very useful practice.

Note that in the targeting system 14, the size of the impact mark can be set arbitrarily, but if the size of the impact mark is set according to the distance as described above, the impact mark may become too small and visibility may be impaired. It will get worse. Therefore, in the targeting system 14, it is preferable to display the impact mark in a large size.

For example, FIG. 10 shows a target panel 51 similar to that shown in FIG. 9, in which a bullet impact mark is displayed in a size similar to the distance in an actual shooting competition, and a target panel 51 is displayed to increase the visibility of the impact mark. A confirmation mark is displayed. In Figure 10, the confirmation impact mark is shown as a circle with gray hatching, and a small circle concentric with the confirmation impact mark is displayed in a size similar to the distance in an actual shooting competition. It shows the impact mark.

In this way, by displaying the impact mark and the confirmation impact mark in a double circle, the visibility of the impact mark can be increased, and the impact mark can also be used to determine whether or not the impact has hit the target. can be accurately confirmed. That is, it is difficult to accurately confirm on the screen whether or not the bullet has landed on the target just by displaying the confirmation impact mark.

Note that, for example, the confirmation impact mark may be displayed semitransparently. In this way, inputting the display size of the impact mark and confirmation impact mark, setting whether to display or hide the confirmation impact mark, inputting the transparency of the confirmation impact mark, etc. can be performed using the operations displayed on the display section of the PC 15. This can be done on the screen. Furthermore, although not shown in FIG. 10, numbers indicating the order in which the bullets were detected as shown in FIG. 9 may be displayed together with the bullet impact mark and the confirmation impact mark.

Further, in the target system 14, patterns such as display positions and shapes of the targets T1 to T5 can be arbitrarily set. Then, in the target system 14, by simply specifying a pre-registered pattern, targets T1 to T5 arranged according to that pattern can be displayed on the target panel 51.

For example, eight types of patterns are shown in FIG. 11 for each display position and shape of targets T1 to T5.

As shown in FIG. 11, circular or square targets can be placed as appropriate, and stop targets can be placed at arbitrary positions.

For example, in an actual shooting competition, it takes time and effort to change the placement positions of these targets, but with the target system 14, targets T1 to T5 can be easily changed by simply selecting a pre-registered pattern. The arrangement can be changed.

Next, FIG. 12 shows an example of a target image displayed on the display 30 when a mover competition is performed using the target system 14. For example, the display 30 displays a target panel 51, a score panel 52, and a bullet meter panel 53, similar to the operation screen 50 in FIG.

For example, in a mover competition, as shown in the upper part of FIG. 12, a line L is displayed along the horizontal direction approximately in the center of the target panel 51, and a mover target MT is displayed so as to be in contact with the upper side of the line L. Then, when the mover competition starts, the mover target MT moves left and right in the horizontal direction along the line L, and the user can target the moving mover target MT.

Further, when it is detected that the BB bullet 12 has landed at the display position of the mover target MT, a fixed target shadow MT' is displayed at the display position, as shown in the lower part of FIG. 12.

For example, if a competition that should normally be held at a distance of 10 m is held at a distance of 3.3 m to the target device 11, and the bullet speed is 80 m/s, the flight time of a 10 m bullet is 10/80 = 0.125 seconds. On the other hand, the flight time of 3.3m is 3.3/80=0.041 seconds. In other words, the bullet impact is detected 0.084 seconds faster than in the actual competition.

Therefore, if the width of the mover target MT is 60 mm and the mover target MT moves a distance of 1 m in 5 seconds, the display 30 will show that the width of the mover target MT is 20 mm and the mover target MT is 330 mm. By setting the distance to be traveled in 5 seconds, the user can practice under conditions equivalent to those of an actual competition.

As mentioned above, since the impact is detected 0.084 seconds faster than in the actual competition, the impact is shifted forward in the moving direction of the mover target MT by 330/5 x 0.084 = 5.54 (mm). It turns out. Therefore, in the targeting system 14, by setting the delay amount used in the impact delay process to 0.084 seconds, the impact mark is displayed after a delay of 0.084 seconds from the timing when the impact is detected (after the mover target MT moves in the forward direction). can do. This allows the user to predict the movement of the mover target MT and display the impact mark at the target.

Since the targeting system 14 is equipped with a bullet speed meter function, for example, by simply setting the shooting distance, the display size and bullet diameter of the mover target MT can be automatically set, and the bullet velocity can be determined based on the bullet speed at the time of impact. The amount of delay used in delay processing can be determined. In other words, the target system 14 can calculate an appropriate delay amount and execute the impact delay process by simply setting the shooting distance without inputting the delay amount into the delay amount input section 60.

Although not shown, in the mover competition as well, the image displayed in the background of the mover target MT can be arbitrarily selected, similar to the target image in FIG.

Next, FIG. 13 shows an example of a target image displayed on the display 30 when playing a plate competition using the target system 14. For example, the display 30 displays a target panel 51, a score panel 52, and a bullet meter panel 53, similar to the operation screen 50 in FIG.

As shown in FIG. 13, targets T1 to T8 are displayed on the target panel 51, of which targets T6 to T8 are blocked by a jammer J, which is a donut-shaped blocker. For example, one shot is fired at one target T and the shot lands on targets T1 to T5, and the competition ends the moment the shot hits the jammer J for targets T6 to T8.

Even in such a plate competition, as described above with reference to FIG. 9, by setting the sizes of the targets T1 to T8 according to the distance to the target device 11, more realistic practice can be performed. .

As described above, with the target system 14, various competitions can be played more realistically, and more useful practice can be performed by dealing with aiming errors without adjusting the sighting device.

<Second configuration example of target device according to embodiment of the present invention>
FIG. 14 is a perspective view showing a second configuration example of a target device according to an embodiment of the present invention.

For example, the target device 11 shown in FIG. 1 is configured to have a size that matches the display 30 of a predetermined monitor size. Therefore, for example, if the monitor size of the display owned by the user is different from the size of the target device 11, the user needs to obtain the display 30 that matches the size of the target device 11. Therefore, even if the target device 11 is sized to match the display 30 of a predetermined monitor size, it is possible to use displays of various monitor sizes in combination, thereby improving user convenience. be able to.

Therefore, the configuration of the target device 11A that can be used in combination with a display 30 of any monitor size will be described below.

As shown in FIG. 14, the targeting device 11A is arranged on the front side of the display 30 that displays a target image, and similarly to the targeting device 11 in FIG. Equipped with a function to output a detection signal for detecting.

The dashed-dotted arrow in FIG. 14 indicates an example of the path of the fired BB bullet 12, and the side where the BB bullet 12 is heading toward the target device 11A (lower right side in FIG. 14) is the target device. The front side of the target device 11A is the front side, and the opposite side (upper left side in FIG. 14) is the back side of the target device 11A. Then, the BB bullet 12 fired at the target image displayed on the display 30 is moved toward the lower side of the near side of the target device 11 after the impact force is absorbed by the deflection of the target plate 123 of the target device 11A. They fall onto the collection mat 130 placed at the top of the screen and are collected without scattering.

Here, the collection mat 130 is made of, for example, boa fabric or pile fabric, which absorbs the impact of the BB bullet 12 falling and has a low repulsion property (slow repulsion) that prevents the BB bullet 12 from rebounding. It is preferable to use a material that has the property of returning to its original shape. For example, by using a collection mat 130 that has soft protrusions such as hair or irregularities on its surface, the BB bullets 12 that have fallen onto the collection mat 130 are prevented from rolling, and the BB bullets 12 are more reliably scattered. can be prevented. Further, when collecting the BB bullets 12 scattered on the collection mat 130, for example, by lifting both ends of the collection mat 130 and narrowing it back and forth, the BB bullets 12 are placed in the center of the collection mat 130. can be collected and easily collected. More preferably, it has been confirmed that by using a thick so-called microfiber towel folded in half, the BB bullets 12 can be completely collected without scattering.

Furthermore, as will be described later, when a bag-shaped collection mat 130 of a size that can accommodate the rolled target device 11A is adopted, for example, when the target device 11A is transported, the collection mat 130 Target device 11 can be protected. Of course, the collection mat 130 is not limited to a bag-like one. Note that it is sufficient that the BB bullets 12 can be collected without scattering, and for example, a box-shaped collection tray (not shown) or the like may be placed in front of the target device 11A.

As shown in FIG. 14, the target device 11A includes an upper side fixing member 121, a lower side fixing member 122, a target plate 123, a back plate 124, side support members 125 and 126, acoustic sensors 127-1 to 127-4, and It is configured to include a control unit 128.

The upper side fixing member 121 is, for example, a member that has a U-shaped cross section when the target device 11A is viewed from the side, and has a length that is approximately the same as the width of the target plate 123 and the back plate 124. The upper side fixing member 121 has an elongated shape along the upper sides of the target plate 123 and the back plate 124, and is attached to the upper sides of the target plate 123 and the back plate 124 using a plurality of screws at predetermined pitch intervals. Fixed.

The lower side fixing member 122 has the same shape as the upper side fixing member 121, and is fixed to the lower sides of the target plate 123 and the back plate 124.

The target plate 123 is a transparent member that allows the target image displayed on the display 30 to pass through, and is made of a soft material that can deflect and catch the impact of the BB bullet 12 fired toward the target image by a soft air gun. A sheet-like member is used. For example, the target plate 123 is preferably made of a soft vinyl chloride resin with a thickness of 1.5 mm, which has a slow recovery speed against deformation due to impact. Further, the target board 123 is stretched substantially vertically in front of the display 30 and is flat as a whole, that is, in a planar manner so that no deflection occurs. It is fixed to the side surface on the front side, and the lower side is fixed to the side surface on the front side of the lower side fixing member 122.

The back plate 124 is made of a transparent and soft sheet-like member similar to the target plate 123, for example, a soft vinyl chloride resin with a thickness of 1.5 mm, and is formed on the back side of the target plate 123 (display 30 side as seen from the user). ). That is, like the target plate 123, the back plate 124 has an upper side fixed to the back side surface of the upper side fixing member 121 and a lower side fixed to the back side side of the lower side fixing member 122 in a planar manner.

In this way, the target plate 123 is fixed to the front side surfaces of the upper side fixing member 121 and the lower side fixing member 122, and the back plate 124 is fixed to the back side sides of the upper side fixing member 121 and the lower side fixing member 122. . Thereby, a space 129 is provided between the target plate 123 and the back plate 124 at an interval corresponding to the width of the upper surface of the upper side fixing member 121 and the width of the lower surface of the lower side fixing member 122. The space 129 is open on the left and right sides, so that the acoustic sensor 127 can stably acquire impact sounds, similar to the closed space 29 of the target device 11 described above with reference to FIG. It is possible to achieve the effect of

The side support members 125 and 126 are rod-shaped members (so-called threaded bolts) with threads formed on the side surfaces over the entire length, and are formed to be slightly longer than the vertical width of the target plate 123 and the back plate 124. be done. Further, when viewing the target device 11A from the front, the side support member 125 supports the left end portions of the upper side fixing member 121 and the lower side fixing member 122, and the side support member 126 supports the upper side fixing member 121 and the lower side fixing member. The right end of 122 is supported.

For example, two nuts (not shown) are screwed into the screws at the top of the side support members 125 and 126 so as to sandwich the top side fixing member 121, and screws at the bottom of the side support members 125 and 126 are screwed together. Two nuts (not shown) are screwed together to sandwich the lower side fixing member 122. Thereby, both ends of the upper side fixing member 121 and the lower side fixing member 122 are supported. Here, by adjusting the position of a nut (not shown), the interval between the upper side fixing member 121 and the lower side fixing member 122 can be adjusted, and a certain amount of tension can be applied to the target plate 123 and the back plate 124. .

Further, by supporting the upper side fixing member 121 and the lower side fixing member 122 using nuts, the side support members 125 and 126 can be easily removed. Then, with the side support members 125 and 126 removed from the upper side fixing member 121 and the lower side fixing member 122, the target plate 123 and the back plate 124 can be rolled up around the lower side fixing member 122, for example. . In this way, by rolling the target device 11A into a roll, it is possible to improve portability, storage properties, and the like.

Similar to the acoustic sensors 27-1 to 27-4 in FIG. 1, the acoustic sensors 127-1 to 127-4 acquire the impact sound generated when the BB bullet 12 lands on the target plate 123, and An acoustic signal according to the change in amplitude of is supplied to the control unit 128.

The acoustic sensors 127-1 to 127-4 are arranged on the back side of the target plate 123, close to each of the four corners of the target plate 123, and at the optimal position for acquiring impact sound. It is fixed in a space 129 between rear plates 124. For example, the acoustic sensor 127-1 is arranged near the left end of the downwardly facing surface of the upper side fixing member 121, and the acoustic sensor 127-2 is arranged near the right end of the downwardly facing surface of the upper side fixing member 121. . Further, the acoustic sensor 127-3 is arranged near the left end of the upper side of the lower side fixing member 122, and the acoustic sensor 127-4 is arranged near the right end of the upper side of the lower side fixing member 122. Note that, hereinafter, the acoustic sensors 127-1 to 127-4 will be simply referred to as acoustic sensors 127 when there is no need to distinguish between them.

In this way, the acoustic sensor 127 is placed in a space 129 between the target plate 123 and the back plate 124, which are fixed in parallel at a predetermined interval, so that impact sound is generated between the target plate 123 and the back plate 124. By resonating, a stable acoustic signal can be obtained.

Note that although this embodiment describes a configuration using four acoustic sensors 127-1 to 127-4, the number of acoustic sensors 127 is not limited to four. For example, depending on the size or shape of the target device 11A, it is possible to use a number of acoustic sensors 127 such as 3, 6, or 8 that can appropriately measure the landing position and the like. For example, when six acoustic sensors 127 are used, the acoustic sensors 127 are arranged not only at the four corners but also at the center of the top side and the center of the bottom side.

The control unit 128 houses the signal processing board 28 described above with reference to FIG. A signal line (not shown) for inputting signals is connected. Further, a signal cable 16 connected to the PC 15 in FIG. 2 is connected to the control unit 128.

Furthermore, the target device 11A can be used in a self-supporting state by attaching the self-supporting members 131 and 132 and the auxiliary fixing plates 133 to 136.

The self-supporting members 131 and 132, like the side supporting members 125 and 126, are rod-shaped members (so-called threaded bolts) having threads formed on the side surfaces over the entire length.

The auxiliary fixing plate 133 is a plate-shaped member for connecting the upper end portions of the side support member 125 and the self-supporting member 131, and the auxiliary fixing plate 134 is the upper end portion of the side support member 126 and the self-supporting member 132. It is a plate-shaped member for connecting. The auxiliary fixing plate 135 is a plate-shaped member for connecting the lower end portions of the side support member 125 and the self-supporting member 131, and the auxiliary fixing plate 136 is a plate-shaped member for connecting the lower end portions of the side support member 126 and the self-supporting member 132. It is a plate-shaped member for connecting.

In this way, the self-supporting members 131 and 132 are arranged at positions apart from the side supporting members 125 and 126 at intervals corresponding to the lengths of the auxiliary fixing plates 133 to 136. Thereby, the target device 11A can stand on its own on, for example, a table at four points, including the side support members 125 and 126 and the self-supporting members 131 and 132.

The target device 11A is configured in this way and can be used in a shooting competition in which the target image displayed on the display 30 is used as a target to compete for the accuracy of the impact position. That is, the target device 11A detects the impact sound when the BB bullet 12 hits the target plate 123 using the acoustic sensors 127-1 to 127-4, and accurately determines the impact sound based on the impact position determined based on the detection signal. At this time, a landing mark can be displayed on the display 30.

Here, for example, when using a 32-inch wide monitor-sized display 30, the target device 11A is configured using a target plate 123 of a size corresponding to the 32-inch wide screen. When the target device 11A is attached to the 32-inch wide display 30, the upper side fixing member 121 is arranged along the upper side of the display 30, and the lower side fixing member 122 is arranged along the lower side of the display 30. .

Therefore, in this case, the center of the detectable area on the target board 123 and the center of the display area of the display 30 are in an overlapping state so as to substantially coincide with each other. Here, the detectable area on the target plate 123 is an area other than the area where the upper side fixing member 121 and the lower side fixing member 122 are provided behind the target plate 123, and the target plate 123 is free when the BB bullet 12 lands. This is an area where it is possible to vibrate.

At this time, the targeting device 11A uses the coordinates of the impact position determined from the impact sound when the BB bullet 12 lands as the coordinates when displaying the impact mark on the display 30, so that the target device The impact mark can be displayed so as to overlap the impact position where the bullet 12 actually landed.

On the other hand, the target device 11A having a size corresponding to a 32-inch wide screen may be used in combination with a small display 30 that is 32 inches wide or less. However, in a configuration in which the display 30, which is smaller than the target device 11A, is arranged on the back side of the target device 11A, the center of the detectable area on the target plate 123 and the center of the display area of the display 30 may not match, and the target The target image ends up being displayed at a position away from the center of the board 123. Therefore, if the coordinates of the impact position determined from the impact sound when the BB bullet 12 lands are used as the coordinates when displaying the impact mark on the display 30, the BB bullet 12 actually hits the target plate 123. The impact mark is displayed at a different location than the original impact location.

Therefore, the target device 11A corrects the position of the center of the target image displayed on the display 30, which is shifted from the center of the detectable area on the target plate 123, by correcting the display position when displaying the impact mark on the display 30. It is necessary to perform center setting processing to set the center correction amount. The above-described aiming correction process can be applied to this center setting process. For example, in the center setting process, the position of the center of the target image displayed on the display 30 with respect to the center of the detectable area on the target plate 123 is determined as the deviation as described above, and the inverse of the value of the deviation is used for center correction. Set as amount.

Then, when displaying the impact mark on the display 30, the targeting device 11A uses the center correction amount set in the center setting process to mark the impact mark corresponding to the impact position determined from the impact sound when the BB bullet 12 lands. Correct the display position of. As a result, even when the target device 11A is used in combination with the small display 30, the impact mark is displayed on the display 30 so as to substantially match the impact position where the BB bullet 12 actually impacts on the target plate 123. can do.

<Example of use of target device>

FIG. 15 shows an example of a configuration in which a target device 11A having a size corresponding to a 32-inch wide screen is used in combination with a smaller 19.5-inch wide display 30.

As shown in FIG. 15, when viewing the target device 11A from the front, the user can see through the transparent target plate 123 and the back plate 124 the information displayed on the display 30 disposed on the back side of the target device 11A. The target screen 151 can be visually recognized.

Further, FIG. 15 shows a state in which the target screen 151 is displayed in full screen on the display 30. The target screen 151 has a display layout in which a target panel 51A is placed in the center, a vertically long score panel 52A is placed on the left side of the target panel 51A, and a vertically long bullet velocity meter panel 53A is placed on the right side of the target panel 51A. ing.

The target screen 151 can be displayed on the display 30 using the function of the sub-display included in the PC 15 in FIG. 2.

For example, an operation screen 50A (see FIG. 17) similar to the operation screen 50 described with reference to FIG. 3 is displayed on the display unit of the PC 15 installed at the user's hand, and the user can Various operations can be performed on the operation screen 50A. Then, when the user performs an operation to instruct display of the target screen 151, the target screen 151 is displayed as a sub-window for the operation screen 50A so as to overlap the operation screen 50A. Subsequently, the user performs an operation of dragging the target screen 151 on the operation screen 50A to move it to the display 30 functioning as a sub-display of the PC 15. Thereafter, the user performs an operation to instruct full-screen display of the target screen 151, so that the target screen 151 is displayed in full-screen on the display 30.

Here, in the example shown in FIG. 15, when the target device 11A is viewed from the front, the display 30 is placed on the lower right side of the entire target device 11A, and is located at a position offset from the center of the target plate 123. The target image is displayed. In this way, even if the target image is displayed at a position shifted from the center of the target board 123, the target device 11A can adjust the size of the display 30 by setting the monitor specifications of the display 30 and performing the center setting process. Shooting can be performed using the target screen 151 displayed according to the target, and the impact mark can be accurately displayed within the display range of the target panel 51A.

For example, the monitor specifications of the display 30 can be set using a size setting screen 161 as shown in FIG.

For example, the user can input a monitor size representing the size of the display area of the display 30 on the size setting screen 161. Further, the PC 15 can detect the number of dots (number of pixels in the horizontal direction x number of pixels in the vertical direction) of the display 30 used as a sub-display, and display it on the size setting screen 161 as the monitor specification of the display 30. I can do it. In the example of FIG. 16, the monitor size of the display 30 is input as 19.5 inches, and the number of dots on the display 30 is detected as 1600×900.

Then, the PC 15 recognizes the resolution of the display 30 and the width and height dimensions of the display area of the display 30 based on the monitor size of the display 30 and the number of dots of the display 30, and determines the monitor specifications of the display 30. It can be displayed on the size setting screen 161 as follows. At this time, the PC 15 calculates the resolution (for example, dpi: dots per inch) of the display 30 based on the number of dots on the display 30 and the diagonal dimensions of the display area of the display 30, and then calculates the width and height. Dimensions can be calculated.

Here, which monitor is set as the display 30 depends on whether or not the target screen 151 is displayed as a subwindow. For example, when the target screen 151 is displayed as a subwindow, the number of dots on the screen on which the subwindow is placed can be detected and the number of dots can be displayed on the size setting screen 161. On the other hand, when the target screen 151 is not displayed as a sub-window, the number of dots on the monitor displaying the operation screen 50A is detected, and when shooting at the target panel 51A of the operation screen 50, the impact mark is displayed. can be set to be displayed accurately. Then, when the OK button on the size setting screen 161 is operated, monitor specifications using the size setting screen 161 are set.

Note that if the number of dots that will not be displayed on the entire screen is selected on the size setting screen 161, the width and height dimensions calculated from the monitor size and the number of dots will be the width of the display area of the actual display 30. Dimensions and height dimensions will be different. In this case, the settings for the width and height dimensions can be changed by performing operations on the size setting screen 161 so that they match the width and height dimensions of the display area of the actual display 30. In response to the change, the PC 15 recalculates and sets the resolution corresponding to the change.

Furthermore, when the monitor size of the display 30 used in combination with the target device 11A is changed, the display magnification of the target panel 51 is automatically adjusted so that the display size fits within the display area of the display 30. For example, when the size of a standard target used in an actual shooting competition is taken as 100%, the target panel 51 is set so that it is displayed in a size that fits within the display area of the display 30 with a monitor size of 19.5 inches. The display magnification will be adjusted to 61.9%. That is, a change in the "monitor size" on the size setting screen 161 is automatically reflected in the "target size". Note that even if the "target size" on the size setting screen 161 is changed, it is not reflected in the "monitor size".

For example, when using a smaller display 30, the user may select a target panel 51 that is the same size as a standard target used in an actual shooting competition, rather than a small target panel 51 that fits within the display area of the display 30. You may want to display 51. In this case, by changing the "target size" on the size setting screen 161 to 100%, a portion of the target panel 51 will be displayed on the display 30 in the same size as a standard target used in an actual shooting competition. Ru.

Note that, for example, the target device 11A can perform shooting by using the target panel 51 displayed on the display 30 as a target, or by pasting target paper on which a target is printed on the back plate 124. In this case, the target mark is displayed only on the target panel 51A of the operation screen 50A displayed on the display section of the PC 15 in FIG.

At this time, the target can be reduced or enlarged and printed according to the size of the target paper, and by setting the reduction or enlargement magnification in "Target Size" on the size setting screen 161, the target can be printed on the target paper. It is possible to match the correspondence between the target panel 51A and the target panel 51A. For example, when the target panel 51 displayed in a size that fits on the 32-inch wide display 30 is reduced and printed on A4 paper, the reduction magnification is 39%. Note that the monitor size of a television receiver that is generally referred to as 32-inch wide is 31.5 inches, and 31.5 inches is set as the default value of the monitor size. Then, by setting the "target size" on the size setting screen 161 to 39% and operating the OK button, the correspondence relationship between the A4 size target paper and the target panel 51A on the operation screen 50A is matched. can be used.

Here, the width and height of the display area of the display 30, the number of dots, etc. may be manually set by the user using the size setting screen 161. Further, the position of the display 30, the position of the target paper, etc. may also be manually set by the user. Note that even if the target panel 51 protrudes outside the display area of the display 30 due to the specifications or settings of the display 30, the width and height of the display area of the display 30 may be set larger, or the target panel 51 You can respond by setting the size of the image to a smaller size. Such a relationship between the display area of the display 30 and the size of the target panel 51 can be handled by finely adjusting them, recognizing the resolution of the display 30, and performing center setting processing.

Next, the center setting process will be explained with reference to FIG. 17.

The operation screen 50A shown in FIG. 17, like the operation screen 50 shown in FIG. , an X-direction correction amount input section 57, a Y-direction correction amount input section 58, a landing delay setting operation section 59, and a delay amount input section 60 are displayed.

Note that the operation screen 50 in FIG. 3 has a display layout in which a horizontally long score panel 52 is displayed above the target panel 51, and a horizontally long bullet velocity meter panel 53 is displayed below the target panel 51. On the other hand, on the operation screen 50A, similarly to the target screen 151 in FIG. 15, a vertically long score panel 52A is arranged on the left side of the target panel 51A, and a vertically long bullet velocity meter panel 53A is arranged on the right side of the target panel 51A. The display layout is as follows.

For example, when performing center setting processing, the user performs an operation to instruct display of the target center correction screen 171, so that the target center correction screen 171 is displayed as a sub-window on the operation screen 50A so as to overlap with the operation screen 50A. Ru. Then, with the target center correction screen 171 displayed, the user aims a predetermined number of BB bullets 12 toward the center of the target panel 51A of the target screen 151 displayed as shown in FIG. conduct.

At this time, as shown in FIG. 15, if the center position of the target panel 51A of the target screen 151 is in the lower right direction with respect to the center of the target board 123, as shown in FIG. A predetermined number of impact marks are displayed at the lower right of the center position of 51A. Then, for these landing marks, a grouping circle 63 as described above with reference to FIG. 4) will be displayed.

Furthermore, the target center correction screen 171, like the grouping setting screen 61 in FIG. and a deviation representing the amount of deviation in the Y direction. Then, when the apply (correct the center) button on the target center correction screen 171 is operated, the inverse of this deviation value is calculated based on the impact position determined from the impact sound when the BB bullet 12 lands. This is set as a center correction amount for correcting the display position of the displayed bullet impact mark. That is, the reciprocal of the deviation value displayed on the target center correction screen 171 is used by the system as a correction value for the system to recognize the landing on the center of the target panel 51A as the landing on the center of the target plate 123. Set.

In this way, the targeting device 11A uses the grouping function to aim at the center of the target, detects the impact of a plurality of BB bullets 12, and selects the grouping center 62 of the grouping circle 63 at the impact position. can be found. Then, a landing mark is displayed based on the detected landing position, which is the inverse of the deviation amount of the grouping center 62 of the grouping circle 63 from the center of the detectable area on the target plate 123 in the X-axis direction and the Y-axis direction. It can be used as a center correction amount for the position. As a result, when a bullet lands on the grouping center 62 of the grouping circle 63 determined in the center setting process, the landing position is corrected so that the deviation becomes zero.

Therefore, for example, the user only needs to shoot several shots aiming at the center of the target, group them according to their impact marks, and operate the apply button (correct the center) on the target center correction screen 171. The impact mark can be displayed to match the actual impact position.

Note that if the landing position of the BB bullet 12 is outside the range of the target panel 51A, the grouping circle 63 is not displayed on the target panel 51A.

<Configuration example of impact detection display processing section>

FIG. 18 is a block diagram illustrating an example of a functional configuration of a landing detection display processing section that has a function of performing the center setting process as described above when using a display 30 that is smaller than the target device 11A.

The landing detection display processing section 71A shown in FIG. 18 includes a landing position detection section 72, a landing mark display section 73, a correction amount calculation section 74, and a correction amount acquisition section, similar to the landing detection display processing section 71 shown in FIG. 5 described above. 75, and a setting application section 76. In addition, the impact detection display processing section 71A includes a size setting processing section 77 and a center setting processing section 78.

The size setting processing unit 77 obtains the monitor size representing the size of the display area of the display 30 that is input using the size setting screen 161 as described with reference to FIG. 16 above. Furthermore, the size setting processing unit 77 can detect the number of dots (number of pixels in the horizontal direction×number of pixels in the vertical direction) of the display 30 on which the target screen 151 is displayed as a subwindow. Then, the size setting processing unit 77 recognizes the resolution of the display 30 based on the monitor size and the number of dots of the display 30, determines the width and height of the display area of the display 30, and displays the impact mark as the monitor specification. It can be set in section 73.

Furthermore, the size setting processing unit 77 can calculate the display magnification of the target panel 51 based on the monitor size of the display 30 and display it on the size setting screen 161, as described with reference to FIG. 16 above. can. Furthermore, when the display magnification of the target panel 51 is changed by performing an operation on the size setting screen 161, the size setting processing unit 77 causes the target panel 51 to be displayed on the display 30 in accordance with the display magnification. Configure the settings. Then, the size setting processing section 77 can set the display magnification of the target panel 51 to the impact mark display section 73.

When the target center correction screen 171 of FIG. 17 described above is displayed, the center setting processing unit 78 is supplied with the impact position detected by the impact position detection unit 72 based on the impact sound acquired by the acoustic sensor 27. be done. Then, the center setting processing unit 78 displays the position of the center of the target image displayed on the display 30 with respect to the center of the detectable area on the target plate 123 based on the impact position supplied from the impact position detection unit 72. This is set in the impact mark display section 73 as the center correction amount for the display position of the impact mark.

For example, like the correction amount calculation section 74, the center setting processing section 78 can calculate the center correction amount using the above-mentioned grouping function. That is, the center setting processing unit 78 detects the landing of a predetermined number of BB bullets 12 by repeatedly shooting at the center of the target a predetermined number of times, and determines the grouping center 62 of the landing positions of these shots. The inverse of the deviation value of the grouping center 62 from the center of the target in the X-axis direction and the Y-axis direction is calculated as the center correction amount. Thereby, the landing mark display section 73 can correct the display position of the landing mark according to the center correction amount.

The impact detection display processing section 71A is configured as described above, and by the center setting processing section 78 setting the center correction amount in the impact mark display section 73, the impact mark display section 73 can be set to the target plate 123. A landing mark can be displayed on the display 30 so as to substantially match the landing position where the BB bullet 12 actually landed.

By the way, in the above-described center setting process, the point on the target plate 123 is used as a reference point for aligning the impact position where the BB bullet 12 actually lands on the target plate 123 and the display position of the impact mark displayed on the display 30. The description is given assuming that the center of the detectable area and the center of the display area of the display 30 are used. In addition, as a reference point for this alignment, an arbitrary position in the detectable area on the target plate 123 and a predetermined position in the display area of the display 30 corresponding to the arbitrary position can also be used. In short, once the reference point is set, the impact mark can be displayed to approximately match the impact position of the BB bullet 12 as long as the positional relationship between the target plate 123 and the display 30 does not change.

Alternatively, in order to perform this alignment, the display 30 may be arranged so that the lower left end of the display area of the display 30 matches the lower left end of the detectable area on the target board 123. In this case, the reference point for detecting the impact position of the BB bullet 12 is the lower left end of the detectable area on the target plate 123, and the reference point for displaying the impact mark on the display 30 is the display area of the display 30. The lower left end of By setting the reference point in this manner, it is possible to associate the actual impact position of the BB bullet 12 on the target plate 123 with the display position of the impact mark displayed on the display 30.

In this way, the reference for this alignment is not limited to using the center of the detectable area on the target plate 123 and the center of the display area of the display 30.

The most important point when using the target device 11A in combination with displays 30 of various monitor sizes is to recognize the resolution (number of dots per unit length) of the display 30 used in combination with the target device 11A. It is to be. That is, by setting the resolution of the display 30, the impact mark display section 73 can associate the impact position of the BB bullet 12 with the display position of the impact mark, and can associate the impact position of the BB bullet 12 with the display position of the impact mark. Collision marks can be displayed as shown below.

As described above, the size setting processing unit 77 can detect the number of dots (number of pixels in the horizontal direction×number of pixels in the vertical direction) of the display 30. However, even if the number of dots is the same, there are displays 30 of various monitor sizes (for example, 21.5 inches, 23.6 inches, 23.8 inches, 24 inches, etc.). Therefore, the resolution of the display 30 cannot be specified only by the number of dots on the display 30, and the impact position of the BB bullet 12 and the display position of the impact mark cannot be correlated.

Therefore, when the user inputs the monitor size of the display 30 using the size setting screen 161 in FIG. 16, the size setting processing unit 77 can recognize the resolution of the display 30 according to the number of dots of the display 30. . For example, assuming that the pixels of the display 30 are arranged in a grid, the resolution dpi, which is the number of dots per inch, can be calculated using the following formula ( Calculated according to 1).

Then, by calculating, for example, the number of dots per 1 mm (= dpi/25.4) from this resolution dpi, the landing position (unit: mm) can be made to correspond to the display position, and the reciprocal of this is the dot pitch (unit: mm). Therefore, by multiplying this dot pitch by the number of dots in the horizontal direction and the number of dots in the vertical direction, the width and height (mm) of the display area of the display 30 can also be determined.

In this way, the size setting processing unit 77 recognizes the resolution of the display 30 and sets the resolution of the display 30 as well as the width and height dimensions of the display area of the display 30 in the impact mark display unit 73 as monitor specifications. do.

As a result, the impact mark display unit 73 displays a impact mark at the impact position of the BB bullet 12 detected by the impact position detection unit 72 based on the resolution of the display 30, regardless of the monitor size of the display 30. can be displayed accurately. That is, if the reference point for detecting the impact position of the BB bullet 12 and the reference point for displaying the impact mark on the display 30 match, the impact mark display section 73 will display the impact mark based on the resolution of the display 30. By using the landing position of the BB bullet 12 with respect to the reference point as the display position when displaying the landing mark, the landing mark can be displayed to match the landing position of the BB bullet 12.

<Example of use of notebook PC>

FIG. 19 shows an example of use in which the display section of a notebook PC 15 is used as a target instead of the display 30 in the target device 11A.

As described above, the target device 11A can use the display 30 as a sub-display of the PC 15, and can also be used without the display 30 by placing the display section of the PC 15 on the back side as shown in FIG. I can do it. Note that during actual use, the collection mat 130 shown in FIG. 14 is placed over the keyboard portion of the PC 15.

In this way, even when using the PC 15 equipped with a display unit smaller than the target device 11A, by performing target center correction using the target center correction screen 171, the impact mark can be adjusted to approximately match the impact position. can be displayed.

In addition to directly operating the PC 15, the user may also operate the PC 15 remotely using, for example, a tablet PC (not shown) connected to the PC 15 via wireless communication. It's okay.

As described above, the user can place the displays 30 of various sizes at arbitrary positions with respect to the target device 11A and perform shooting. At this time, as described above, even if the display 30 is not installed so that the center of the target panel 51A coincides with the center of the target plate 123 when the target device 11A is viewed from the front, the BB bullet 12 will land. The impact mark can be displayed to approximately match the position.

Note that even if the display 30 with a monitor size of 32 inches or more is used for the target device 11A configured with a size of 32 inches, by performing the above-mentioned center setting process, the impact position of the BB bullet 12 can be approximately adjusted. Impact marks can be displayed to match. However, in this case, it is preferable to protect the display 30, which is a portion outside the target device 11A, from the BB bullets 12.

Further, although the center of the display 30 does not need to be the center of the target panel 51A, since the center of the display 30 is set as the center of the system for detecting the impact position of the BB bullet 12, another target can be selected. It is expected that discrepancies will occur when changing settings. Therefore, it is desirable to set the monitor specifications of the display 30 as described above with the center of the display 30 and the center of the target panel 51A aligned.

In addition, the above-mentioned aiming correction processing, impact delay processing, and center setting processing can be applied not only to a shooting system using BB bullets 12 but also to an optical shooting system using laser light, infrared rays, etc. can. In such an optical shooting system, the position and orientation of the gun barrel 18 of a ray gun, etc. relative to the target are optically detected, and the impact position is determined according to the orientation and position of the gun muzzle at the time of firing. In the system as well, since shooting competitions are held by humans holding a ray gun or the like in their hands, it is unavoidable that the gun barrel 18 shakes. Therefore, adjusting the aim using the grouping function as described above is also effective in optical shooting systems.

Note that each process explained with reference to the above flowchart does not necessarily have to be processed in chronological order according to the order described in the flowchart, but rather processes that are executed in parallel or individually (for example, parallel processing or object processing). processing). Further, the program may be processed by one CPU, or may be processed in a distributed manner by multiple CPUs.

Further, the series of processes (information processing method) described above can be executed by hardware or software. When a series of processes is executed by software, the programs that make up the software execute various functions on a computer built into dedicated hardware or by installing various programs. The program is installed on a general-purpose personal computer, for example, from a program recording medium on which the program is recorded. Note that a program acquired through communication may be installed.

FIG. 20 is a block diagram showing an example of the hardware configuration of a computer that executes the above-described series of processes using a program.

An input/output interface 205 is further connected to the bus 204 . The input/output interface 205 includes an input section 206 consisting of a keyboard, mouse, microphone, etc., an output section 207 consisting of a display, speakers, etc., a storage section 208 consisting of a hard disk, nonvolatile memory, etc., and a communication section 209 consisting of a network interface, etc. A drive 210 that drives a removable medium 211 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory is connected.

In the computer configured as described above, the CPU 201 executes the above-described series by, for example, loading a program stored in the storage unit 208 into the RAM 203 and executing it via the input/output interface 205 and the bus 204. processing is performed.

The program executed by the computer (CPU 201) is, for example, a magnetic disk (including a flexible disk), an optical disk (CD-ROM (Compact Disc-Read Only Memory), DVD (Digital Versatile Disc), etc.), a magneto-optical disk, or a semiconductor disk. The information may be recorded on a removable medium 211, which is a package medium such as a memory, or may be provided via a wired or wireless transmission medium such as a local area network, the Internet, or digital satellite broadcasting.

The program can be installed in the storage unit 208 via the input/output interface 205 by attaching the removable medium 211 to the drive 210. Further, the program can be received by the communication unit 209 via a wired or wireless transmission medium and installed in the storage unit 208. Other programs can be installed in the ROM 202 or the storage unit 208 in advance.

Note that this embodiment is not limited to the embodiment described above, and various changes can be made without departing from the gist of the present disclosure.

For example, the invention may be applied to any competition or game in which a flying object is hit against a target, specifically, to a target system such as darts or blowguns. In this case, a dart or a blowgun arrow may be displayed on the target image instead of the bullet hole mark. Naturally, it is necessary to round off the tips of darts and blowgun arrows instead of BB bullets so that they do not pierce the target plate 24. Furthermore, by increasing the strength of the target plate 24, the present invention can also be applied to a target system for a real gun (air gun, etc.), which has stronger energy upon impact than a toy gun (soft air gun).
