Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a target for shooting training, and more particularly to means for eliminating the consumption of a target used for shooting training, reducing costs, and improving safety.
[0002]
[Prior art]
Conventionally, a method has been adopted in which a solid target is driven by a motor to perform a hidden operation, or a target is projected onto a screen to perform a hidden operation.
[0003]
[Problems to be solved by the invention]
The conventional target of the above method has the following problems. (a) Solid targets or projection screens are severely damaged and deformed by the impact of bullets and must be replaced regularly. (b) In order to prevent bullets, metal materials cannot be used, and wood is mainly used, so quality varies. (c) An accident may occur when a supervisory person replaces a solid target or projection screen. (d) A place to store the replacement target or screen is required.
[0004]
An object of the present invention is to provide a target that is not damaged even when a bullet is landed, the deformation of the target image is repaired, and an exchange operation is unnecessary.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a projection device that directly projects a target image onto a slope of a breakwater, a target image monitoring camera that photographs a projected target image, and a target image that is photographed after landing. A projection target composed of a target image control device that corrects an image signal sent to a projection device so as to return to an original target image is proposed.
[0006]
More specifically, the target video control apparatus includes a target image memory that stores an image signal from the target image monitoring camera, a recognition circuit that recognizes a difference between a target image captured after landing and an original target image, Based on the recognition result, the control circuit corrects the projection image so that it becomes the original target image, and the projection image display unit reconstructs the corrected projection image and sends it to the projection apparatus.
[0007]
When the target is made non-consumable according to the present invention , the above problems (a) to (d) can be solved. That is, (a) since the projection target of the present invention projects directly onto the slope of the dam, it is not damaged by the bullet landing and does not need to be replaced. The deformation of the target image due to the shape change of the breakwater due to landing is taken by, for example, shooting the projected target image with a target image monitoring camera installed behind the shooter, correcting the projected image with the target video control device, and target by landing Correct the deformation of the image. (b) Since the projection target of the present invention does not exist as a real object on the slope of the breakwater, no consideration is required for preventing a bullet. (c) In the supervision at the time of shooting, the target part can be completely unmanned and automated, and it is not necessary for a person to replace a solid target or a projection screen, and there is no possibility of an accident occurring. (d) No place to store replacement targets or screens.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a projection target according to the present invention will be described with reference to FIGS.
[0009]
FIG. 1 is a side view showing a system configuration of an embodiment of a projection target according to the present invention. The projection target according to the present invention includes a projection device 1, a target image monitoring camera 4, and a target image control device 5. The projection device 1 is installed, for example, at the upper front portion of the shooting seat 6 and directly projects the target image 2 onto the slope of the breakwater 3. The target image monitoring camera 4 is installed, for example, in the upper rear part of the shooting seat 6 and captures the target image 2 projected on the slope of the breakwater 3. The target image control device 5 corrects the target image 2 by controlling the projection device 1 based on the target image photographed after landing from the target image monitoring camera 4.
[0010]
In order to solve the problems (a) to (d), it is basically sufficient to include the projection device 1 that directly projects the target image 2 onto the slope of the breakwater 3.
[0011]
In the embodiment of FIG. 1, the target image 2 is directly projected onto the slope of the breakwater 3 by, for example, the projection device 1 installed at the front upper part of the shooting seat 6, so that a target that is not consumed by bullets can be obtained.
[0012]
For the deformation of the target image 2 due to the shape change of the breakwater 3 due to landing, the projected target image 2 is photographed by, for example, the target image monitoring camera 4 installed behind the shooting seat 6, and the target image control device 5. The target image 2 to be projected is corrected by the above and the deformation of the target image 2 due to landing is corrected.
[0013]
When the target image 2 projected directly onto the slope of the pier 3 by the projection device 1 lands on the pier 3, the shape of the pier 3 changes when the shape of the pier 3 changes. The target image 2 whose shape has collapsed is photographed by the target image monitoring camera 4, corrected by the target video control device 5, and the deformation of the target image 2 is corrected. The appearance / disappearance of the target image 2 is controlled according to a control signal from the outside to the target image control device 5.
[0014]
FIG. 2 is a block diagram illustrating an example of a circuit configuration of the target video control device 5. The target video control device 5 includes a target image memory 7 that stores an image signal from the target image monitoring camera 4, a recognition circuit 8 that recognizes a difference between the captured target image 2 and the original target image, and a recognition result. The control circuit 10 corrects the target image 2 projected to become the original target image based on the above, and the projection image display unit 9 that reconstructs the corrected projection image and sends it to the projection apparatus 1.
[0015]
The target video control device 5 stores the image signal from the target image monitoring camera 4 in the target image memory 7. The recognition device 8 recognizes the difference between the target image 2 that has been captured and stored and the original target image. The control circuit 10 causes the projection image display unit 9 to reconstruct the target image 2 based on the recognition result, and sends the corrected image signal of the target image 2 to the projection device 1.
[0016]
FIG. 3 is a diagram illustrating an example of an image correction procedure. The target video control device 5 adds or deletes pixels in dot units for the captured target image 2 so as to become an original target image. Since the breakwater 3 is an inclined surface, the deformation of the breakwater 3 tends to have irregularities only in the vertical direction. Therefore, the normal target image 2 can usually be corrected only by correction in the vertical direction. . If the slope of the breakwater 3 is gentle and cannot be corrected by only the vertical correction, the horizontal correction is also performed.
[0017]
FIG. 3A shows image data of the target image 2 sent to the projection apparatus 1 before shooting. When landing on the slope of the breakwater 3 at the start of shooting, the slope is removed, so that the outer shape of the target image 2 photographed by the target image monitoring camera 4 becomes a worm-eaten state as shown in FIG. Therefore, as shown in FIG. 3C, opposite correction data is given so as to be opposite to the outer shape of the photographed target image 2, that is, the protruding portion is recessed and the recessed portion is protruding. As shown in 3 (D), the projected target image 2 is corrected to the shape before shooting.
[0018]
【The invention's effect】
According to the present invention, the following effects can be obtained. (a) Since the projection target of the present invention projects directly onto the slope of the breakwater, it is not damaged by the impact of bullets and does not need to be replaced. (b) Since the projection target of the present invention does not exist as a real object on the slope of the breakwater, no consideration is required for preventing a bullet. (c) In the supervision at the time of shooting, the target part can be completely unmanned and automated, and it is not necessary for a person to replace a solid target or a projection screen, and there is no possibility of an accident occurring. Consumables such as solid targets or projection screens are eliminated, reducing costs. (d) No place to store replacement targets or screens.
