Description

Technical Field

[0001] This invention relates to the field of simulated shooting technology, and more specifically, to a photographic intelligent simulated shooting launcher based on image comparison. Background Technology

[0002] The core risk of firearms used in traditional shooting training comes from the physical projectiles. Laser projection in optoelectronic shooting still poses certain safety hazards. Live-fire shooting uses real firearms (such as pistols and rifles) and ammunition (including bullets and gunpowder). The core risk is fatal safety hazards. It is the riskiest and most restricted of the three methods due to "high-threshold compliance, high cost, and strong scenario constraints." The cost is extremely high, with firearms, ammunition, and maintenance all being "high-consumption." The experience threshold is high, and the requirements for personnel's physical fitness and psychology are strict. Optoelectronic targets are mostly "sensor array + circuit board" structures, which are expensive (a single 10-meter target costs several hundred to several thousand yuan). After long-term use, the sensors are prone to failure due to dust and vibration, requiring regular replacement. The lifespan of the laser tube of the laser emitter is limited (about 1,000-5,000 hours). Frequent replacement is required in high-frequency use scenarios, resulting in high accumulated maintenance costs.

[0003] Therefore, there is an urgent need for an image comparison-based intelligent simulated shooting launcher to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an image comparison-based intelligent simulated shooting launcher. Equipped with a front sight, a high-precision camera, a power display screen, and a control motherboard, this invention uses neither lasers nor projectiles; aiming is achieved solely by "observing" the target image through the camera. There is no possibility of "projectile injury," making it safe for use in scenarios with extremely high safety requirements, such as home entertainment, youth shooting training, and shopping mall experience zones. This photographic shooting invention eliminates the need for electronic targets; only standard target paper is required for shooting training. It is portable, easy to deploy, and has lower maintenance costs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an image comparison-based intelligent simulated shooting launcher, comprising a simulated gun body, a simulated gun barrel fixedly installed inside one side of the simulated gun body, a high-precision camera fixedly installed at the end of the simulated gun barrel away from the simulated gun body, a front sight provided on the top of the high-precision camera, a front rail fixedly installed at the bottom of the front sight, a front rail fixedly installed on the top of the high-precision camera, a rear sight provided on the top of the simulated gun body, a rear rail fixedly installed at the bottom of the rear sight, a rear rail fixedly installed on the top of the simulated gun body, and a grip fixedly installed at the bottom of the simulated gun body. A cheek rest assembly is fixedly installed at the end of the gun body away from the simulated gun barrel. A shoulder rest assembly is fixedly installed on the side of the cheek rest assembly away from the simulated gun body. A battery display screen is located at the bottom of the simulated gun body. A push-button switch is located on the side of the battery display screen near the shoulder rest assembly. A Type-C charging port is located on the side of the push-button switch near the shoulder rest assembly. The push-button switch and the Type-C charging port are located at the bottom of the simulated gun body. A battery is fixedly installed inside the simulated gun body. A trigger assembly is located between the grip and the battery. A control motherboard is fixedly installed inside the simulated gun body. The control motherboard is a Raspberry Pi Zero 2W motherboard. A memory module is connected to the connection end of the control motherboard. The output end of the push-button switch is connected to the input end of the control motherboard. A Bluetooth module is connected to the connection end of the control motherboard. A tablet computer is connected to the connection end of the Bluetooth module. The trigger assembly is configured as a Hall sensor electronic trigger, and the output terminal of the Hall sensor electronic trigger is connected to the input terminal of the control motherboard.

[0006] In a preferred embodiment, the high-precision camera includes an OV5647 camera module and a 16mm 3MP lens.

[0007] In a preferred embodiment, the battery is configured as a 5V 4000mAh-3A-XH2.54 lithium battery.

[0008] In a preferred embodiment, the memory module is configured as a SanDisk 32GB memory card.

[0009] In a preferred embodiment, the front rail seat is disposed on the front rail, and the front rail seat is slidably connected to the front rail.

[0010] In a preferred embodiment, the rear track seat is disposed on the rear track, and the rear track seat is slidably connected to the rear track.

[0011] In a preferred embodiment, the input terminal of the control motherboard is connected to the output terminal of the battery, and the Type-C charging port is electrically connected to the battery.

[0012] In a preferred embodiment, the output terminal of the control motherboard is connected to the input terminal of the power display screen, and the connection terminal of the high-precision camera is connected to the connection terminal of the control motherboard.

[0013] The technical effects and advantages of this invention are as follows: This invention fixes a standard pistol / rifle target paper to a target bracket 10 meters away from the shooting position, or affixes it to a wall, and illuminates it. A tablet computer connects to the simulated rifle via Bluetooth. The user "aims" at the bullseye on the screen using a high-precision camera on the simulated rifle. The high-precision camera continuously captures images of the bullseye on the screen at a high frame rate. Pulling the trigger selects a frame as a calibration image to identify whether it is a pistol or rifle target. After successful identification, the image is used as a comparison benchmark model. The system performs high-speed comparison of each frame captured by the camera in real time with the "benchmark model," and calculates the lens offset (dx, dy), which directly represents the center of the lens optical axis on the X and Y axes. The system records the calculated physical offset distance d relative to the target center when the user pulls the trigger. Based on the preset target paper ring radius, the system determines the ring number corresponding to the distance d. If d exceeds the maximum ring radius, it is considered a miss. The current aiming offset is displayed in real time on the tablet screen in a graphical manner (such as a crosshair or a red dot). After "shooting", the calculated "impact point" is marked on the target center image on the tablet, and the ring number is displayed. This invention uses neither laser nor projectile; aiming is achieved solely by "observing" the target surface image through a camera. There is no possibility of "projectile injury". It can be safely used in scenarios with extremely high safety requirements, such as home entertainment, youth shooting training, and shopping mall experience areas. This invention's photo-based shooting does not require an electronic target surface; only standard target paper is needed for shooting training. It is easy to carry, deploy, and maintain.

[0022] The battery 13 is a 5V 4000mAh-3A-XH2.54 lithium battery.

[0029] The specific implementation method is as follows: When using this invention, a standard pistol / rifle target is fixed on a target support 10 meters away from the shooting position, or affixed to a wall, and illuminated. The tablet computer is connected to the simulated gun via Bluetooth. The user "aims" at the bullseye on the screen using the high-precision camera 5 on the simulated gun. The high-precision camera 5 continuously captures images of the bullseye on the screen at a high frame rate. Pulling the trigger assembly 12 selects a frame as a calibration image to identify whether it is a pistol target or a rifle target. After successful identification, the image is used as a comparison benchmark model. The system performs high-speed comparison between each frame captured by the camera in real time and the "benchmark model." Lens offset calculation yields the translational offset (dx, dy), which directly represents the center of the lens optical axis on the X and Y axes.

The system determines the number of rings corresponding to the distance d based on the preset target paper ring area radius. If d exceeds the maximum ring area radius, it is determined to be a miss. The current aiming offset is displayed in real time on the tablet screen in a graphical manner (such as a crosshair or a red dot). After "shooting", the calculated "impact point" is marked on the target center image on the tablet and the number of rings is displayed. This invention has neither laser nor projectile.
