Description

  The present invention relates to a shooting training system that performs shooting training by irradiating an image projected on a screen with a laser beam imitating an actual bullet.

  In the shooting training without using an actual bullet, a predetermined image, for example, a training image such as a target image is projected on a screen using a video projection device such as a projector, and a laser bullet (laser light) is emitted on the projected image ( Irradiation). That is, an image showing the landing point of a laser bullet fired on a screen is shot using a shooting device such as a CCD (Charge-Coupled Device) camera, and the target hit rate etc. using the shot image. Training is performed by determining Whether or not the laser bullet hits the target projected on the screen is determined based on the training video projected on the screen by the video projection device and the video showing the landing point photographed by the photographing device. This is determined by detecting the landing point of the laser bullet.

  Here, in the conventional shooting training device, in order to photograph the reference point projected on the screen in order to adjust the distance between the screen, the image projection device and the photographing device, and the landing point of the laser bullet In the case of photographing, photographing is performed without changing the state of the photographing device (see, for example, Patent Document 1). Therefore, in both the case of shooting the reference point and the case of shooting the landing point, it is affected by noise such as natural light and light from the room light, and the resolution at the time of shooting the reference point and the shooting point of the landing point are affected. Both resolutions can be reduced. Therefore, in the conventional shooting training apparatus, the shooting training apparatus is installed in a room darkened using a black curtain or the like to perform shooting training.

  By the way, when it is necessary to darken the room where the shooting training apparatus is installed by using a black curtain or the like, there is a problem that preparation takes time and effort. Even when the room is darkened and the reference point projected on the screen is photographed, for example, light based on a portion other than the reference point of the image including the reference point projected on the screen becomes noise, and the resolution It is difficult to obtain an image of a high reference point. Furthermore, even if the room is darkened and the impact point of the laser bullet is shot, for example, the training image projected on the screen becomes noise and it is difficult to obtain a high-resolution impact point image. There are problems such as.

  An object of the present invention is to perform a precise adjustment by eliminating the influence of noise in a shooting training using a laser beam imitating an actual bullet, which can be quickly installed and can detect a landing point with high accuracy. It is to provide a training system.

High shooting training can be realized.

  Hereinafter, a shooting training system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining an outline of a shooting training system according to an embodiment of the present invention. The shooting training system includes a projector (video projection device) 6, a CCD (Charge-Coupled Device) camera (imaging device) 8, and a control device 10 (illustrated in FIG. 1) arranged on a normal line extending from the approximate center of the screen 2. Is omitted, see FIG. 2). In FIG. 1, an alternate long and short dash line indicates an image projected by the projector 6, and a broken line indicates an image captured by the CCD camera 8. In addition, the projector 6 and the CCD camera 8 are arranged so that the optical axis direction of the projection lens of the projector 6 and the optical axis direction of the photographing lens of the CCD camera 8 coincide with each other, for example, the center of the projection lens and the photographing lens. It is arranged and integrated so that the center is located on the same vertical line. In FIG. 1, a person who performs a shooting training (shooter) uses a handgun (laser handgun) 4 that emits (irradiates) a laser bullet (laser light) and is projected on a screen 2 (training image). Shooting training is performed by emitting (irradiating) a laser bullet (laser light) to the target.

  Here, as the handgun 4, a handgun that can fire an actual bullet and a device (laser light emitting device) for emitting a laser bullet imitating the actual bullet is used. The laser bullet emitted from the handgun 4 is laser light having a wavelength in an invisible region, and the irradiation position of the laser light emitted from the handgun 4 to the target on the screen 2 cannot be seen by the gunner. It is like that. For example, infrared light is used as the laser light having a wavelength in an invisible region.

  FIG. 2 is a block configuration diagram of the shooting training system according to the embodiment of the present invention. As shown in FIG. 2, the shooting training system controls processing in the projector 6 that projects the training video, the CCD camera 8 that captures the landing point of the laser bullet (laser irradiation position), the projector 6, and the CCD camera 8. A control device 10 is provided. In the shooting training system, for example, a training video is projected on the screen 2 (see FIG. 1) by the projector 6 based on the control by the control device 10 constituted by a personal computer, and the CCD is based on the control by the control device 10. The irradiation position of the laser beam irradiated by the handgun 4 on the target in the training video projected on the screen 2 by the camera 8 is photographed.

  Here, as shown in FIG. 3, the CCD camera 8 includes a first optical filter 8a used when photographing an image having a color corresponding to a wavelength in the visible region, that is, an adjusted image, and a laser having a wavelength in the invisible region. A second optical filter 8b used for photographing a light irradiation position, that is, a laser light irradiation position emitted from the handgun 4 is provided. The first optical filter 8a is an optical filter that satisfactorily transmits light having a wavelength corresponding to the color of the adjustment image. For example, the first optical filter 8a favorably transmits light having a wavelength corresponding to green that is the color of the adjustment image. The second optical filter 8b is an optical filter that satisfactorily transmits light having the wavelength of the laser light emitted from the handgun 4. For example, the second optical filter 8b favorably transmits light having an infrared wavelength. In the CCD camera 8, the first optical filter 8 a and the second optical filter 8 b are exchanged by driving a filter driving unit (optical filter exchange means) 8 c based on control by the control device 10.

  FIG. 4 is a block configuration diagram of the control device 10 in the shooting training system according to the embodiment of the present invention. As shown in FIG. 4, the control device 10 includes a data control unit 20 that controls data processing in the control device 10. Connected to the data control unit 20 are a communication control unit 22 that controls communication between the projector 6 and the CCD camera 8 and a video data storage unit 24 that stores video data projected onto the screen 2 via the projector 6. ing. In addition, the data control unit 20 includes a shooting data storage unit 26 that stores shooting data shot through the CCD camera 8 and a data storage unit 28 that stores information used for adjusting the projected video and the shot video. It is connected.

  The video data storage unit 24 stores video data projected on the screen 2 by the projector 6, that is, adjustment image data projected on the screen 2 by the projector 6 and data indicating a training video. Here, the adjustment image refers to the adjustment for converting the coordinates of the video (captured video) taken by the CCD camera 8 into the coordinates of the video (projected video) projected on the screen 2 by the projector 6. It is an image having a color corresponding to the wavelength of the visible region to be used. For example, a green round image or the like is used. The training video is a moving image targeting a robber who escapes from a convenience store, for example. The moving image for one second is composed of several tens of frames (for example, 30 frames) of still images, and the video data storage unit 24 stores still images of all the frames constituting the moving images as training videos. ing. In addition, data indicating the position of the target (criminal) in each still image, for example, coordinates indicating the position of the target are stored in the video data storage unit 24.

  The photographing data storage unit 26 stores photographing data photographed by the CCD camera 8, that is, adjustment images photographed by the CCD camera 8 and data indicating the irradiation position of the laser light on the screen 2. Here, in the CCD camera 8, when the adjusted image is captured, the first optical filter 8 a that favorably transmits light corresponding to the color green of the adjusted image is captured based on the control by the control device 10. Mounted on the lens. Further, when photographing the irradiation position of the laser beam, the second optical filter 8b that favorably transmits light having the wavelength of the laser beam used as a laser bullet is attached to the photographing lens based on the control by the control device 10. Is done. Therefore, in the CCD camera 8, when taking the adjustment image, light having a wavelength other than the light corresponding to green is removed as noise. Further, when shooting the irradiation position of the laser beam, the training image projected on the screen 2 by the projector 6 is removed as noise, and only the point (landing point) indicating the irradiation position of the laser beam irradiated on the screen 2 is obtained. Is filmed.

  Further, the data storage unit 28 adjusts for coordinate conversion, that is, the coordinates of the xy coordinate system in the projected image projected onto the screen 2 by the projector 6 and the photographed image captured by the CCD camera 8. Setting information used to perform coordinate conversion that matches the coordinates of the XY coordinate system is stored. Here, the setting information will be described with reference to FIG.

  FIG. 5 is a diagram illustrating a state in which the adjustment image stored in the data storage unit 28 is projected onto the reference range and the reference position. In FIG. 5, the screen 2, the projector 6 and the CCD camera 8 face each other at a predetermined position, that is, on a normal extending from the approximate center of the screen 2 with a distance of, for example, 4 m. 2 shows a projected video 40 including an adjustment image 30 projected on the screen 2 by the projector 6 and a captured video 50 taken by the CCD camera 8 when installed in the projector. Further, as shown in FIG. 5, the center of the adjustment image 30, the origin (0, 0) of the xy coordinate system set for the projected video 40, and the origin (0, 0) of the XY coordinate system set for the captured video 50 The screen 2, the projector 6, and the CCD camera 8 are arranged at predetermined positions so that (0, 0) match. Here, the distance between the screen 2 and the projector 6 and the CCD camera 8, the data indicating the arrangement position of the projector 6 and the CCD camera 8 with respect to the screen 2, the reference range of the adjustment image 30, for example, the radius of the adjustment image 30 Data indicating the reference position of the adjustment image 30, for example, coordinates (0, 0) indicating the center of the adjustment image 30, coordinates (-30, 0) indicating the intersection of the adjustment image 30 and the X (x) axis, ( 30, 0), information including coordinates (0, 30) and (0, −30) indicating the intersection of the adjusted image 30 and the Y (y) axis is stored in the data storage unit 28 as setting information. Note that the radius of the adjustment image 30 is calculated using coordinates stored as data indicating the reference position of the adjustment image 30.

  Further, the data storage unit 28 stores correction data, that is, data indicating the amount of deviation between the aiming position and the landing point based on the reaction that occurs when actual bullet shooting is performed. Here, when shooting using an actual bullet, the muzzle is slightly upward due to the reaction that occurs during shooting, and the bullet hits a position slightly above the position where the aim is set. For this reason, a skilled shooter takes into consideration the reaction that occurs during shooting and shoots with aiming at a position slightly below the target in advance. However, when shooting training is performed using a laser handgun that emits a laser bullet imitating a real bullet, there is no reaction as when shooting a real bullet, so the laser beam is irradiated at the position where the aim is set, It is not possible to obtain an appropriate training effect assuming real shooting. In view of this, data indicating the amount of deviation between the aiming position based on the reaction that occurs when shooting with an actual bullet for each type of handgun and the landing point of the actual bullet is stored as correction data. Note that the amount of deviation between the aiming position and the landing point caused by the reaction in the case of actual bullet shooting differs depending on the caliber, type, range, and type of the actual ammunition. Therefore, by conducting a shooting experiment in which the caliber of the handgun, the type, the type of ammunition, and the range are combined in multiple patterns in advance, the amount of deviation between the aiming position and the landing point of the actual ammunition in each pattern is measured, and the measured data Is stored in the data storage unit 28 as correction data.

  Next, with reference to the flowchart of FIG. 6, the coordinate conversion process in the shooting training system according to the embodiment of the present invention will be described. First, as shown in FIG. 1, the projector 6 and the CCD camera 8 are arranged so as to be positioned on the normal line extending from the approximate center of the screen 2. At this time, the projector 6 and the CCD camera 8 are arranged and integrated so that the center of the projection lens of the projector 6 and the center of the photographing lens of the CCD camera 8 are located on the same vertical line. The camera 8 is arranged at an arbitrary distance from the screen 2 within a predetermined distance, for example, a range of 4 to 6 m.

  Next, the adjusted image is projected onto the screen 2 via the projector 6 based on the control by the control device 10 (step S10). That is, the green and round image data stored in the video data storage unit 24 is transmitted from the control device 10 to the projector 6 via the communication control unit 22, and the projector 6 displays the green color based on the received video data. A round adjustment image is projected onto the screen 2. The adjusted image is projected onto the screen 2 so as to be positioned at the center of the range in which the video is projected by the projector 6.

  Next, the adjustment image projected on the screen 2 is taken by the CCD camera 8 based on the control by the control device 10 (step S11). Here, in the CCD camera 8, the first optical filter 8 a is attached to the photographing lens based on the control by the control device 10, and the adjusted image is photographed through the first optical filter 8 a. That is, the adjustment image having a green color corresponding to the wavelength in the visible region is photographed through the first optical filter 8a that favorably transmits the light corresponding to the green color, whereby the adjustment image can be photographed with a high resolution. . Note that the shooting data of the adjustment image shot by the CCD camera 8 is transmitted from the CCD camera 8 to the control device 10. In the control device 10, the shooting data of the adjusted image transmitted from the CCD camera 8 is received via the communication control unit 22 and stored in the shooting data storage unit 26 of the control device 10.

  FIG. 7 is a diagram illustrating an example of an adjustment image photographed in the shooting training system according to the embodiment. As shown in FIG. 7, the adjustment image 32 is adjusted so that the center of the adjustment image 32 and the center of the projection video 42 coincide with each other, that is, the origin in the xy coordinate system set for the projection video 42. The image 32 is projected on the screen 2 so as to coincide with the center of the image 32.

  Next, the range (projection range) and position (projection position) of the adjustment image projected on the screen 2 are detected based on the adjustment image photographed in step S11 (step S12). For example, as shown in FIG. 7, an XY coordinate system with the center of the captured video 50 as the origin is set. Then, the coordinates indicating the center of the adjustment image 32 taken in the XY coordinate system of the photographed video 50, the coordinates indicating the intersection of the line segment passing through the center and parallel to the X axis, and the adjustment image 32, and the Y axis passing through the center. The coordinate indicating the intersection of the line segment parallel to the adjustment image 32 is detected. Then, based on the detected coordinates, the value of the radius of the adjustment image 32 is calculated as data indicating the projection range of the adjustment image 32 and stored in the data storage unit 28. Further, detected data such as a coordinate indicating the center of the adjustment image 32 is stored in the data storage unit 28 as data indicating the projection position of the adjustment image 32.

  Next, the adjustment image projection magnification is calculated based on the adjustment image projection range detected in step S12 and the adjustment image reference range included in the setting information (step S13). For example, “40” is stored as the radius of the adjustment image 32 (see FIG. 7) stored as the projection range in the photographing data storage unit 26, and the adjustment image 30 stored as the reference range in the data storage unit 28. It is assumed that “30” is stored as the radius of (see FIG. 5). In this case, “40/30” is calculated as the projection magnification. The calculated projection magnification is stored in the data storage unit 28. Further, the distance between the screen 2 and the projector 6 and the CCD camera 8 is calculated based on the projection magnification stored in the data storage unit 28, and the calculated distance is stored in the data storage unit 28.

  Next, the shift amount of the adjustment image is calculated based on the projection position detected in step S12 and the reference position of the adjustment image included in the setting information (step S14). For example, the coordinates (−150, 100) indicating the center of the adjustment image 32 (see FIG. 7) stored as the projection position in the photographing data storage unit 26 and the adjustment image stored as the reference position in the data storage unit 28 Using the coordinates (0, 0) indicating the center of 30 (see FIG. 5), the deviation amount “−150” in the X-axis direction and the deviation amount “+100” in the Y-axis direction are calculated. The calculated deviation amount is stored in the data storage unit 28.

Next, adjustment for converting the coordinates in the XY coordinate system of the video (captured video) taken by the CCD camera 8 into the coordinates in the xy coordinate system of the video (projected video) projected by the projector 6. Is performed (step S15). For example, when the projection magnification is “40/30” and the deviation amounts are “−150” in the X-axis direction and “+100” in the Y-axis direction, The projection magnification and shift amount with respect to the XY coordinate system in the video can be represented by the following mathematical formula (1).
(X, y) = {40/30 (X−150), 40/30 (Y + 100)} (1)
Here, (x, y) indicates coordinates in the xy coordinate system of the projected image, and (X, Y) indicates coordinates in the XY coordinate system of the captured image. Therefore, by using Equation (1), the coordinates in the XY coordinate system of the captured image can be converted to the coordinates in the xy coordinate system of the projected image, and both coordinate systems can be made to correspond accurately. The above mathematical formula (1) is stored in the data storage unit 28 as an adjustment result used in the coordinate conversion (step S16).

  Next, shooting training using the shooting training system according to the embodiment of the present invention will be described. First, as shown in FIG. 1, the screen 2, the projector 6, and the CCD camera 8 are arranged at predetermined positions, and the image projected on the screen 2 is processed by the same process as the process in the flowchart of FIG. 6. Adjustment is performed to convert the coordinates in the XY coordinate system set in the captured image captured by the above method into coordinates in the xy coordinate system set in the projected image projected onto the screen 2 by the projector 6.

  Next, the training video is projected onto the screen 2 by the projector 6. And a gunner performs shooting training using the handgun 4 (refer FIG. 1) with which the laser bullet (laser beam emission device) imitating a real bullet was mounted | worn. That is, as shown in FIG. 1, a laser beam having a wavelength in an invisible region is irradiated onto a target included in a training image projected on the screen 2 by the projector 6. When performing the shooting training, data indicating the type and caliber of the handgun 4 and the assumed type of actual ammunition are input to the control device 10 via an input unit (not shown).

  Here, the irradiation position of the laser beam irradiated to the target included in the training video is photographed by the CCD camera 8. In the CCD camera 8, a second optical filter 8 b that favorably transmits light having the wavelength of the laser light is mounted on the photographing lens in order to accurately record the irradiation position of the laser light. Therefore, in the CCD camera 8, only the irradiation position of the laser beam is photographed without taking the training video. In the CCD camera 8, the first optical filter 8 a mounted on the photographing lens is replaced with the second optical filter 8 b based on the control from the control device 10, and the irradiation position of the laser light imitating an actual bullet is changed. Shooting is performed. Further, the photographing data indicating the irradiation position photographed by the CCD camera 8 is transmitted to the control device 10 and stored in the photographing data storage unit 26 (see FIG. 4).

  Next, the control device 10 detects the landing point of the laser bullet in the training video. In other words, the projection of the training video by the projector 6 and the shooting of the irradiation position of the laser beam by the CCD camera 8 are performed in synchronization based on the control by the control device 10. Therefore, the training image projected on the screen 2 by the projector 6 and the image of the irradiation position photographed by the CCD camera 8 are associated with each other.

  Therefore, first, in the still images constituting the training video stored in the video data storage unit 24, the coordinates indicating the position of the target in the still image corresponding to the shot irradiation position and the captured data storage unit 26 are stored. The irradiation position of the laser beam in the training image is detected using the coordinates of the irradiation position indicated by the stored shooting data of the irradiation position.

Next, the coordinates of the irradiation position are converted into coordinates in the coordinate system in the still image using the adjustment result stored in the data storage unit 28. For example, when the above equation (1) is stored in the data storage unit 28 as an adjustment result, the coordinates (X _HP , Y _HP ) of the irradiation position are applied to (X, Y) in the equation (1). Then, it is converted into the coordinates (x _HP , y _HP ) of the irradiation position in the xy coordinate system with the center of the still image as the origin.

  Next, using the correction data stored in the data storage unit 28, the coordinates of the converted irradiation position are corrected. That is, it corresponds to the type and caliber of the handgun 4 and the type of the actual ammunition inputted when performing the shooting training, and the distance between the screen 2 stored in the data storage unit 28 and the projector 6 and the CCD camera 8. The correction data is extracted from the correction data stored in the data storage unit 28. Next, a correction for shifting the coordinates of the irradiation position is performed in correspondence with the amount of deviation indicated by the extracted correction data, and the corrected coordinates are detected as the landing point of the laser bullet.

  Next, when the coordinates of the detected landing point overlap with the position of the target indicated by the target coordinates, it is determined that the laser bullet has hit the target. When it is determined that the laser bullet hits the target, projection of the training video by the projector 6 is stopped, and an image showing the landing point on the still image is projected onto the screen 2 via the projector 6. Here, the landing point on the still image is indicated by displaying, for example, a red point or the like at a position corresponding to the coordinates of the detected landing point. The image showing the landing point on the still image is stored in the data storage unit 28 as the landing point detection result. If it is determined that the laser bullet is not hitting the target, the projector 6 continues to project the training video and performs the shooting training.

  According to the shooting training system according to the embodiment of the present invention, the adjustment image is taken via the first optical filter in the CCD camera. Therefore, when shooting an adjusted image, light other than the light corresponding to green, which is the color of the adjusted image, can be taken out as noise, and an adjusted image shot at a high resolution can be used. You can make adjustments. Therefore, it is not necessary to make preparations such as darkening a room or the like in which the shooting training system is installed using a black curtain or the like, and the shooting training system can be installed quickly and easily.

  Further, when photographing the irradiation position of the laser light emitted by the handgun in the CCD camera, the image is taken through the second optical filter that favorably transmits the light having the wavelength of the laser light emitted by the handgun. . Therefore, light having a wavelength other than the light having the wavelength of the laser light emitted by the handgun is excluded as noise, the landing point is photographed with high resolution, and whether or not the target has been hit is determined with high accuracy. Can achieve high quality shooting training.

  Moreover, according to the shooting training system according to the embodiment of the present invention, infrared rays, which are laser beams having wavelengths in an invisible region, are used as laser bullets. Therefore, the shooter cannot visually recognize the irradiation position of the laser beam, and is corrected using the amount of deviation between the aiming position based on the reaction that occurs in the case of actual bullet shooting and the landing point of the actual bullet The point displayed on is recognized as the landing point. Therefore, since the shooting training can be performed so that the aim is adjusted in consideration of the reaction that occurs when the actual bullet shooting is performed, an appropriate training effect can be obtained. Furthermore, since the shooter cannot visually recognize the irradiation position, it prevents the shooter from feeling uncomfortable with the mismatch between the landing point displayed and the irradiation position of the laser beam. it can.

  In the shooting training system according to the above-described embodiment, a round green image is used as the adjustment image. However, the shape of the adjustment image is not limited to the round shape, and the color of the adjustment image is also green. It is not limited to. That is, as long as the image has a color corresponding to the wavelength in the visible region, an image having another color may be used. In addition, infrared light is used as the laser light having a wavelength in the invisible region, but laser light other than infrared light may be used as long as the laser light has a wavelength in the invisible region.

  Further, although a projector is used as the video projection device, the video projection device is not limited to the projector. Further, although a CCD camera is used as the photographing device, the photographing device is not limited to the CCD camera. As the CCD camera, either a black and white CCD camera or a color CCD camera may be used. However, when a color CCD camera is used, the infrared cut filter provided as a standard is removed and then the laser is removed. Take a picture of the light irradiation position.

  In the shooting training system according to the above-described embodiment, the center of the projection lens of the projector and the center of the photographing lens of the CCD camera are arranged on the same vertical line, but the optical axis direction is fixed. As long as it is arranged in a state, it may be arranged in any way.

  In the shooting training system according to the above-described embodiment, since the reference range of the adjustment image and the projection range of the adjustment image are similar, the projected adjustment image (circle) is used as the reference range of the adjustment image. ) Is stored, but if the reference range of the adjustment image and the projection range of the adjustment image are similar, the other may be stored as the reference range. For example, the area of the projected adjustment image and the number of pixels of the projected adjustment image may be stored as the reference range.

  Moreover, in the shooting training system according to the above-described embodiment, the case where the projection of the training video is stopped at the stage where it is determined that the laser bullet hits the target is taken as an example, but shooting training is performed using other patterns. You may go. That is, a training image is projected on a screen for a predetermined time, for example, 15 seconds, and a laser bullet is emitted to a target included in the training image for a preset number of times while the training image is projected on the screen. . Then, after the projection of the training video is completed, the shooting training may be performed by detecting the landing point of the laser bullet and determining how many laser bullets hit the target.
