Description

A method and apparatus for simulating shooting Technical Field

[0001] This invention relates to a method and apparatus for simulating shooting. Background Technology

[0002] With the improvement of living standards, people living in peacetime mostly experience realistic war scenes by watching military films and television dramas in theaters or on their sofas at home. While there's tension, the sense of immersion is far from the desired. Therefore, interactive shooting games have emerged. Players can control virtual weapons in the online world to engage in intense combat. However, this experience of playing games through a screen still falls short. Thus, starting around the 1950s, outdoor "real-life combat simulation shooting games" were developed. Because they can provide a tense and exciting real-life experience while ensuring safety, they have become a popular outdoor "field sport" and are recognized as a recreational and fitness activity by governments around the world.

[0003] Since its inception in 1979, laser tag has become a popular recreational and competitive shooting sport worldwide due to its high safety level, as it does not fire any objects directly at the target. As a recreational shooting sport, participants use infrared laser guns to fire beams at designated targets. Each player, in addition to their infrared laser gun, wears an infrared-sensitive signal device to register hits. These infrared-sensitive receivers are typically distributed across the participant's helmet, vest, or other equipment. For example, helmets currently have four receivers, and vests have two each on the front and back. When this equipment is integrated into the arena, it simultaneously registers hits and records scores. In the early 1980s, a system for shooting training using infrared beams (MILES) was developed. The MILES system uses the infrared beams or lasers on firearms to illuminate the "sensitive light receivers" of other participants, thereby automatically registering hits and recording scores.

[0004] Currently, laser tag has evolved into various forms of competitive games, including close-combat simulations, role-playing adventure games, and tactical drills with precise target acquisition. It is popular across all age groups. Laser tag competitions are held at local, regional, national, and international levels. As the demands for fairness and realism in various laser tag games and competitions continue to rise, the difficulty of accurately determining hits has increased significantly. Therefore, existing laser tag games and equipment have several shortcomings: for example, the dispersed distribution of sensitive light signal receivers on the participants' equipment greatly reduces the area for hit detection. For instance, shots to the chest or other areas without light signal receivers, or to the abdomen or legs, may not be considered hits, which is unfair and significantly reduces the realism experienced by the participants.

[0005] In addition, the sensitive light signal receiving devices equipped by participants are easily blocked, either by the participant's shooting or movement posture, or by deliberate obstruction, thus preventing them from hitting the light signal receiving devices.

[0006] Furthermore, because the sensitive optical signal receiving devices are installed on the participant's equipment, they are easily damaged during the participant's activities. For example, if a participant falls or collides with something, the optical receiving devices installed on the helmet and vest may be damaged or worn to varying degrees, thus failing to accurately transmit the hit information.

[0007] Meanwhile, participants will constantly change their body position during the action, and the shooter can only be considered hit if they are facing the light receiving device directly.

[0008] The aforementioned drawbacks stem from the limited availability of optical signal receiving devices on participants. However, addressing these drawbacks by adding more optical receiving devices is extremely difficult due to cost and the impact of equipment weight on participant mobility. To overcome these shortcomings, US Patent 8888491B2, "Optical recognition system and method for simulated shooting," discloses a solution. This solution involves mounting an optical system on the firearm, including a camera and an image processing computer. At the moment the firearm fires, the system captures an image. The image processing system uses the image to obtain the ballistic trajectory and identify whether the hit was a valid target, using this as the basis for hit determination. Clearly, this system suffers from excessive structural complexity and requires high-performance image processing equipment and software, significantly increasing the complexity and overall weight of the determination system. Furthermore, the firing speed of the firearm is limited by the speed of image processing and target recognition. The accuracy of image processing and target recognition is also limited by the capabilities of current software, leading to misjudgments or false triggers.

[0009] Invention Overview

[0010] The purpose of this invention is to provide a method and apparatus for simulating shooting, which increases the light signal receiving area, improves the accuracy of hit determination in simulated shooting, and thus enhances the realism of simulated shooting games.

[0016] In this invention, the wavelength range of the irradiation light source is set according to the response wavelength range of the fluorescent material.

[0017] In one embodiment of the present invention, the illumination source is a laser.

[0018] In another embodiment of the present invention, the illumination light source is an LED, an SLED, or a fluorescent light source.

[0019] In one specific embodiment of this example, the illumination light source is emitted through a lens or collimator to form a focused light source.

[0020] In this invention, the wavelength of the laser light source is set within a safe wavelength range.

[0021] In one embodiment of the present invention, the wavelength of the irradiation light source is set in the visible light range.

[0022] In another embodiment of the present invention, the wavelength of the irradiation light source is preferably set in the invisible light range.

[0023] In one embodiment of the present invention, the fluorescent material portion on the shooting target is set as an effective hit portion according to the game rules.

[0024] In one possible implementation of this embodiment, the portion of the target made of fluorescent material can be attached to the surface of that portion of the target with fluorescent material.

[0025] In another possible implementation of this embodiment, the entire structure of the shooting target composed of fluorescent material is composed of fluorescent material.

[0026] In another possible implementation of this embodiment, the local position structure of the firing target is made of fluorescent material.

[0027] In one embodiment of the present invention, the wavelength range of the illumination light source is different from the emission wavelength range of the fluorescent material.

[0028] In one possible implementation of this embodiment, the wavelength range of the irradiation light source is either less than or greater than the emission wavelength range of the fluorescent material.

[0029] In another possible implementation of this embodiment, the wavelength of the irradiation light source includes the wavelength range of the fluorescent material response.

[0030] In one embodiment of the present invention, the fluorescent material includes at least one response wavelength.

[0031] In another embodiment of the present invention, the fluorescent material comprises a combination of two or more fluorescent materials with different emission wavelength ranges.

[0032] In one embodiment of the present invention, the decay time of the fluorescence intensity of the fluorescent material is greater than the response time of fluorescence detection.

[0033] In one embodiment of the present invention, the fluorescence emitted by the fluorescent part of the target being hit is received by at least one detection device, and the target is determined to be hit.

[0034] In one possible implementation of this embodiment, the detection device receives wavelengths within the range of the emission wavelengths of the fluorescent material of the target.

[0035] In one possible implementation of this embodiment, the detection device is composed of a photoelectric sensor.

[0036] In one possible implementation of this embodiment, the detection device is composed of a photoelectric imaging device.

[0037] In one possible implementation of this embodiment, the detection device includes a filter.

[0038] In one possible implementation of this embodiment, the detection device is positioned within the range of the emission wavelength of the fluorescent material.

[0039] In one embodiment of the present invention, the detection device is disposed on the emitting device of the illumination light source to receive the fluorescence emitted by the fluorescent material of the target being hit.

[0040] In one possible implementation of this embodiment, the emitting device of the illumination light source is equipped with a collimating tube; the portion of the fluorescence emitted by the fluorescent material of the hit target that is parallel to the emitted beam is received by the detection device of the emitting device through the collimating tube; the emitting device determines the hit status of the target based on this and records the identity of the shooter.

[0041] In this invention, the detection device determines the target and / or the point of impact of the target based on the fluorescence emission wavelength of the target.

[0042] In this invention, the detection device starts the detection state at the initial emission state of the irradiation light source.

[0043] In one embodiment of the present invention, the portion of the target made of fluorescent material emits fluorescence in the visible light range, and the target's hit status is determined by the human eye.

[0044] The present invention provides a simulated shooting device according to any of the above-described simulated shooting methods, comprising at least a shooting firing device that emits an illumination light source toward a shooting target; the shooting target is at least partially composed of a fluorescent material; when the light emitted by the illumination light source hits the part composed of the fluorescent material, that part of the shooting target emits fluorescence, and it is determined that the shooting target has been hit.

[0045] In the simulated shooting device of the present invention, the shooting target can be composed of the equipment of a real-life simulated shooting game participant.

[0046] In the simulated shooting device of the present invention, the shooting target is composed of an unmanned vehicle from a simulated shooting game.

[0047] In the simulated shooting device of the present invention, different positions on the same shooting target are equipped with fluorescent materials with different emission wavelengths, and the status of the shooting target being hit is determined based on the different emission wavelengths.

[0048] The technical effects of this invention are significant:

[0049] First, in this invention, the target is at least partially composed of fluorescent material; when the beam of light strikes the portion composed of fluorescent material, that portion of the target emits fluorescence, thus determining that the target has been hit. In this invention, the target may be entirely or partially composed of fluorescent material, and the fluorescent material will emit fluorescence regardless of where it is struck (e.g., equipment used in simulated shooting games such as clothing, helmets, masks, shoes, and backpacks). Therefore, this invention overcomes the deficiency of a small hit detection area in existing technologies, thereby achieving a significantly increased hit detection area.

[0050] In this invention, the impact points on the target, as defined by rules, are made of fluorescent material. Therefore, the target itself can emit fluorescence immediately upon being hit, eliminating the need for sensitive light signal receiving devices on the target's equipment. This ensures accurate hit detection and further enhances the realism of the game experience for participants.

[0051] This invention effectively avoids the drawback of obstructed or damaged optical signal receiving equipment, which can lead to impaired reception of optical signals emitted after a target is hit. It ensures that the reception of optical signals emitted after a target hit does not affect the determination of the target's impact status.

[0052] This invention reduces the weight of participants' equipment to the minimum without affecting judgment in shooting games, thereby increasing participants' mobility in the game. Attached Figure Description

[0062] As shown in Figures 1-8, this invention provides a method for simulating shooting. A beam of light 3 is emitted from a emitting device 9 of at least one illumination light source 1 towards a shooting target 4. The shooting target 4 is at least partially composed of fluorescent material. When the emitted beam 3 hits the portion of the shooting target 4 composed of fluorescent material, that portion of the shooting target 4 emits target fluorescence 6, indicating that the shooting target 4 has been hit. The shooting target 4 in this invention can be a participant in a live-action simulated shooting game. With the popularization of civilian unmanned vehicles (such as robots, drones, unmanned vehicles and cannons, unmanned vessels, etc.), the promotion of games or competitions using unmanned vehicles has become possible. Therefore, the shooting target 4 in the simulated shooting game of this invention can also be composed of unmanned vehicles. For example, robot-simulated shooting games, or drones in drone-simulated air combat games. This invention can avoid physical damage to the shooting target, greatly reducing the wear and tear on the unmanned vehicles used in the game, and is conducive to the promotion of games or competitions using unmanned vehicles.

[0063] This invention is based on the principle that fluorescent materials fluoresce when irradiated with light of a specific wavelength, emitting scattered light (i.e., fluorescence) at wavelengths different from the incident light. In this invention, the areas of the target composed of fluorescent material will fluoresce upon impact, thus emitting fluorescence. Compared to existing scattered light signal receiving devices, this invention significantly increases the light signal receiving area. This improves the accuracy of hit detection in simulated shooting and enhances the realism of the simulated shooting experience.

[0064] As shown in Figures 1, 2, 5, and 6, in this invention, the wavelength range of the irradiation light source 1 is set according to the wavelength range of the response spectrum of the fluorescent material. Since the response wavelength of the fluorescent material is determined by the characteristics of the selected fluorescent material, a fluorescent material within a specific response wavelength range is selected to ensure that the fluorescent material responds and emits fluorescence when irradiated by the irradiation light source 1.

[0065] In a preferred embodiment of the present invention, the illumination light source 1 is a laser. Because laser light sources are easy to focus and their wavelengths can be relatively easily selected, they are a more ideal light source for illumination.

[0066] In other embodiments of the present invention, the illumination light source 1 can be an LED or an SLED, or a fluorescent light source. (The wavelength and wavelength range of the illumination light source meet the requirements for fluorescence emission from the fluorescent material on the target 4. Other light sources besides those mentioned above can also be used as the illumination light source of the present invention.) As shown in FIG3, the LEDs, SLEDs, or fluorescent light sources used in this embodiment are all non-focused light sources. In a preferred embodiment of this invention, the illumination light source 1 can be emitted through a lens or collimator 2, thereby constituting a focused light source. In the embodiment shown in FIG4, the non-focused illumination light source 1 is combined with a collimator 2 to focus the emitted light, thereby achieving the same effect as a focused illumination light source. Another preferred embodiment of this invention is to combine a lens to focus the emitted scattered light. (The structure of combining the illumination light source and the lens is a conventional technology, so it is not shown in the figure.)

[0067] In this invention, the wavelength of the laser source is set within a safe band. This is for the protection of the participants; the wavelength of the laser source used for irradiation should be selected within a range that will not cause harm to human skin and eyes. The safe band range described in this invention should be selected based on known technical standards. This embodiment is suitable for "real-person simulated shooting" games or competitions.

[0068] In one specific embodiment of the present invention, the wavelength of the illumination light source 1 is set in the visible light range. When using a non-focused illumination light source, the fluorescence emitted by the illumination light source 1 and any illuminated target 4 can be captured by the human eye and used as the basis for manual judgment of whether a hit has occurred. This embodiment is more suitable for scenarios where unmanned vehicles are used as shooting targets, such as "drone air combat simulation games," etc. This embodiment is also suitable for simpler "live-action shooting simulation games," where the human eye directly determines whether a hit has occurred. This simplifies the game rules and the difficulty of judgment, thereby reducing the cost of live-action simulation games.

[0069] In another specific embodiment of the invention, the wavelength of the illumination light source is preferably set within the invisible light range. In this embodiment, the beam emitted and illuminated by the emitter cannot be directly captured by the human eye. Especially when using a non-focused illumination light source, the beam emitted by the shooter will typically form a visible beam within the game or competition venue, thus revealing the shooter's position, or simultaneously forming a visible but interfering beam. Therefore, this embodiment is suitable for the requirements of game or competition rules where the shooter cannot be exposed.

[0070] In this embodiment of the invention, the fluorescent material portion on the shooting target 4 is set according to the effective hit points defined in the game rules. Alternatively, the location requiring illumination can be determined based on the importance of different positions on the target. For example, in a live-action shooting game, this could be the head, chest, back, arms, or legs of a person.

[0071] In one specific embodiment of this example, the portion of the shooting target 4 composed of fluorescent material can be a fluorescent material attached to the surface of that portion of the shooting target 4. For example, the surface coating of equipment (clothing, helmet, etc.) in human simulation shooting games, or the surface coating of unmanned vehicles such as robots and drones.

[0072] In another specific embodiment of this example, the parts of the shooting target 4 made of fluorescent material may also be entirely made of fluorescent material. Examples include vests made of textiles containing fluorescent material, helmets made of plastic, etc. Alternatively, unmanned vehicles (such as drones, robots, etc.) made of plastic or metal containing fluorescent material.

[0073] In another specific embodiment of this example, the local structure of the shooting target 4 can be made of fluorescent material. For example, fluorescent material could be used for the chest area of ​​the participant's equipment; or for the fuselage of a drone.

[0074] As shown in Figures 1, 2, 5, and 6, in one embodiment of the present invention, the wavelength range of the illumination light source 1 differs from the emission wavelength range of the fluorescent material. Since the basis for determining hit detection in this invention is the fluorescence emitted by the fluorescent material within its emission wavelength range, when other light with the same emission wavelength range as the fluorescent material appears in the scene (e.g., the wavelength of illumination light source 1, or the wavelength of other illumination light sources 1 overlaps with the fluorescent emission wavelength range of the target), it is impossible to determine whether this light is emitted by the fluorescent material of the hit object. Therefore, in this invention, the wavelength of illumination light source 1 should be different from the emission wavelength of the fluorescent material. This effectively avoids confusion regarding the determination of fluorescence hit, thereby ensuring the accuracy of the determination.

[0075] As shown in Figures 1 and 2, in this specific embodiment, the wavelength of the irradiation light source 1 is either less than or greater than the emission wavelength of the fluorescent material. To distinguish the wavelength of the irradiation light source 1 from the emission wavelength of the fluorescent material, the irradiation light source 1 can use any wavelength band that is less than or greater than the emission wavelength of the fluorescent material.

[0076] As shown in Figures 1 and 2, in another possible implementation of this embodiment, the wavelength of the irradiation light source 1 includes the response wavelength of the fluorescent material, which can ensure that the fluorescent material generates fluorescence to determine the impact after being irradiated.

[0077] In one embodiment of the invention, the fluorescent material used on the shooting target 4 includes at least one response wavelength (i.e., the invention includes at least one fluorescent material). This ensures that the fluorescent material emits fluorescence after the target is irradiated (or hit). In another embodiment of the invention, the fluorescent material comprises a combination of two or more fluorescent materials with different response wavelength ranges, used to distinguish different hit locations on the same shooting target 4. When the same shooting target 4 is composed of multiple fluorescent materials with different emission wavelength ranges, the different wavelengths of fluorescence emitted by the different fluorescent materials on the shooting target 4 can distinguish different parts of the target that have been hit. This embodiment can make corresponding judgments according to the game rules (such as elimination or restricted movement), thereby increasing the participants' sense of realism in the simulated shooting game.

[0078] In this invention, the decay time of the fluorescence intensity of the fluorescent material is greater than the response time for detectable fluorescence. The fluorescent material emits fluorescence after being excited by irradiation, but the fluorescence intensity decays over time after irradiation. The decay time of the fluorescent material is determined by the characteristics of the material itself. To effectively determine a hit, the fluorescence intensity of the selected fluorescent material should decay for a longer time than the response time for detectable fluorescence, allowing sufficient detection time for a judgment.

[0079] As shown in Figures 5 and 6, in one embodiment of the present invention, the fluorescence emitted by the fluorescent material portion of the shooting target 4 is received by at least one detection device 5; ensuring that at least one detection device 5 can receive the fluorescence emitted by the shooting target 4, and triggering a hit determination by the detection device 5. (The detection method and detection device 5 used in the present invention adopt any existing technology used in shooting games.) For example, some unobstructed locations in shooting game venues, or aerial drones used in larger shooting game venues.

[0080] In this embodiment, the receiving wavelength range of the detection device 5 is set within the emission wavelength range of the fluorescent material of the shooting target 4, ensuring that the detection device 5 receives the target fluorescence 6 emitted by the hit shooting target 4.

[0081] In one possible implementation of this embodiment, the detection device 5 is composed of a photoelectric sensor. The detection device 5 can be a photodetector that responds to a specific wavelength band, such as any photoelectric sensor in the prior art, including photodiodes and photomultiplier tubes. When the photoelectric sensor receives light within the wavelength range emitted by the fluorescent material, it generates a corresponding photoelectric signal and triggers a hit detection.

[0082] In another possible implementation of this embodiment, the detection device 5 is composed of a photoelectric imaging device. The detection device used in this scheme can be a photoelectric imaging device that responds to the fluorescence emission band, such as a CCD or CMOS camera. The presence of fluorescence in the image captured by the photoelectric imaging device serves as the basis for hit determination.

[0083] As shown in Figure 6, in a preferred embodiment of this invention, the detection device 5 includes a filter for receiving the emission wavelength of the fluorescent material. In this embodiment, when the wavelength range of the detection device 5 is too large (as shown in Figure 5), especially when the wavelength range of the irradiation light source 1 (the range of the dotted line) and the emission wavelength range of the fluorescent material (the range of the dotted line) are close to or partially overlap, the detection device 5 will simultaneously receive light signals emitted by the irradiation light source 1 and the fluorescent material (the range of the solid line). At this time, it is difficult for the detection device 5 to distinguish whether the received light signal comes from the emission wavelength of the fluorescent material, which is not conducive to the detection device 5 making an accurate hit judgment. Therefore, in this case, in order to achieve accurate judgment, the detection device 5 should only determine a hit within a pre-set receiving wavelength range. Specifically, in this embodiment, an optical filter is added in front of the detection device 5 to limit the spectral range received by the detection device 5 to the selected wavelength range (the solid line part in Figure 6). The light signal received within this wavelength range mainly comes from the emission band of the fluorescent material, which can largely eliminate the interference of stray light 7. This achieves the effect of improving the signal-to-noise ratio and reducing the interference of other light on the judgment, thereby improving the judgment accuracy of the detection device 5.

[0084] The present invention can be implemented by a computer program that pre-sets the receiving wavelength range in the detection device 5, based on the emission wavelength of the selected fluorescent material.

[0085] The working principle of this embodiment is that when using a essentially focused beam (e.g., laser) as the illumination source 1, the luminescent points of the fluorescent material on the target 4 roughly coincide with the hit range of the illumination source 1. Within this hit range, the fluorescent material undergoes a fluorescence reaction within its emission wavelength range. At this time, the detection device 5 receives the emission wavelength mainly from the fluorescent material, thus determining a hit. As shown by the solid line in Figure 6, a photoelectric sensor detection device is used. When the detection device 5 receives wavelengths mainly composed of the emission wavelengths of the fluorescent material with the highest light intensity, the accuracy of the hit determination can be achieved.

[0086] However, when using a non-focused light source, the irradiated area of ​​the light source 1 on the fluorescent material of the target 4 is larger than the hit range aimed at by the light source 1. Therefore, when the target 4 is close to the aiming point but not overlapping, the fluorescent material in other areas can also be irradiated by the light source and produce a fluorescent reaction. In this case, the detection device 5 uses existing technology to intercept the set effective hit area and determines whether fluorescence is captured in that area, and uses this as the basis for determining whether the target has been hit.

[0087] As shown in Figure 7, in this embodiment, the detection device 5 used is a photoelectric imaging device with fluorescence emission wavelength response (e.g., a CCD or CMOS camera). Its working principle is to use the photoelectric imaging device to capture the fluorescence appearing in the image of the aiming point and use it as the basis for determining a hit. Especially when using a non-focused light source, the illumination range of the light source 1 on the target 4 (the area within the dotted circle in Figure 7) is larger than the effective hit range on the target 4 (the central gray circle in Figure 7). At this time, fluorescent materials within the illumination range that are not determined to be effective hits will emit fluorescence (e.g., part of the arm of the person in Figure 7). To make a correct determination of a valid hit, in this embodiment, when the emitting device 9 is activated by the shooter, the detection device 5 (such as a CCD or CMOS camera) composed of photoelectric imaging equipment is triggered to capture an image of the point of impact of the emitted beam 3. When the framing range of the image (the area within the solid square in Figure 7) is larger than the preset effective hit range, the central area of ​​the fluorescent image is cropped as the effective determination range, and the presence or absence of fluorescence within the cropped effective determination range is used as the basis for determination.

[0088] In this invention, the detection device 5 is set within the emission wavelength range of the fluorescent material. For example, multiple detection devices 5 are installed at different locations in a simulated shooting game venue to receive whether a pre-set specific shooting target 4 has been hit; or to receive the fluorescence emitted by any shooting target 4 to determine whether the target has been hit; this embodiment adopts any known method for setting the receiving wavelength range of the detection device.

[0089] As shown in Figure 8, in one embodiment of the present invention, the detection device 5 is disposed on the emitting device 9 of the illumination light source 1 (Figure 8 omits the gun body of the emitting device 9, only showing the barrel 21), and is used to receive the target fluorescence 6 emitted by the fluorescent material of the hit target 4. In this embodiment, since the detection device 5 is disposed on the emitting device 9 of the shooter, the fluorescence emitted by the target 4 can be used to determine the shooter's identity and score. Since the detection device 5 and the emitting device 9 have the same firing direction, only when the shooter aims and emits illumination light towards the target 4 can the target fluorescence 6 received by the detection device 5 from the fluorescent material on the target 4 accurately determine the shooter's identity.

[0090] In this embodiment, since the fluorescence emitted by the fluorescent material of the hit target is scattered light, it may also be captured by the detection device 5 in any unobstructed direction. For example, if each shooter's firing device 9 is equipped with a detection device 5, the fluorescence emitted by the hit target 4 may be captured not only by the detection device 5 on the shooter's firing device 9, but also by the detection devices 5 on the firing devices 9 of other shooters. The fluorescence emitted by the fluorescent material captured by the detection devices 5 on the firing devices 9 of other shooters will not be recorded as the shooter's identity score, but can be used as tactical reference information for other shooters participating in the game.

[0091] As shown in Figure 8, in a preferred embodiment of this example, the emitting device 9 of the illumination light source 1 is provided with a collimating tube 2 that is parallel to the emitted beam 3 (i.e., parallel to the barrel 21); when the fluorescent material of the target 4 is hit, a small portion of the fluorescence 6 emitted and parallel to the emitted beam 3 is received by the detection device 5 on the emitting device 9 through the collimating tube 2. The detection device 5 of the emitting device 9 determines the hit status based on this, and at the same time establishes the identity of the shooter and scores the points.

[0092] The principle of this embodiment is that the collimating tube 2 is a slender tube with the same emission direction as the illumination light source 1. Only when the illumination light source 1 points to and hits the target 4 can a small portion of the fluorescence 6 emitted by the fluorescent material of the target 4 pass through the entire collimating tube 2 unobstructed and be received by the shooter's detection device 5. Meanwhile, light emitted by targets not hit by the shooter in the environment and other stray light 7 cannot reach the shooter's detection device 5 through the collimating tube 2, thus effectively preventing it from entering the shooter's detection device 5, correctly identifying the shooter and scoring.

[0093] In one embodiment of this invention, the detection device 5, mounted on the emitting device 9 of the illumination light source 1, can determine the location of different hit targets 4 and / or the impact point of the same hit target 4 based on the fluorescence emission wavelength of the hit target 4. The specific condition of the hit target 4 can be determined based on the different emission wavelengths of the fluorescent material of the target 4, such as whether the target 4 has completely lost its combat capability and has withdrawn from the game or competition; or whether its movement is restricted due to being hit, etc.

[0094] In a preferred embodiment of this invention, the detection device 5 activates its detection state when the illumination light source 1 is in the emission state. Especially in simulated shooting games or competitions, the detection device 5 mounted on the firing device 9 is only triggered when the firing device aims at the target and fires. This prevents fluorescence emitted from the target 4 struck by other illumination light sources 1 from entering the shooter's detection device 5, thus avoiding any impact on the participant's score or rating. Therefore, this embodiment is suitable for simulated shooting competitions and can accurately reflect the participants' scores.

[0095] In one embodiment of the present invention, the portion of the shooting target 4 composed of fluorescent material emits fluorescence within the visible light wavelength range, and the target's hit status is determined by the human eye. When the emission wavelength of the selected fluorescent material is visible light, the fluorescence generated when the target is hit can be captured by the human eye, and the hit determination can be made accordingly, without the need for additional detection devices. This embodiment is suitable for simple simulated shooting locations, reducing the cost of equipment and detection devices, and achieving the effect of reducing the complexity of shooting location equipment. This embodiment is also suitable for unmanned vehicle simulated shooting games in open spaces, overcoming the situation where it is difficult to determine the hit using the detection device 5 due to the large or uncertain nature of the game field, and can reduce the cost of simulated shooting games or competitions using unmanned vehicles as shooting targets 4.

[0096] The present invention provides a device for simulating shooting, comprising at least a shooting firing device 9 that emits an illumination light source 1 to a shooting target 4; the shooting target 4 is at least partially composed of a fluorescent material; when the illumination light source 1 hits the part composed of the fluorescent material, that part of the shooting target 4 emits fluorescence, thereby determining that the shooting target has been hit.

[0097] The shooting target 4 in this invention can be the equipment of the participants in a live-action shooting game, such as clothing, helmets, etc.

[0098] The shooting target 4 described in this invention consists of unmanned vehicles used in simulated shooting games. Because this invention does not cause physical damage to the unmanned vehicles used in shooting games, it can significantly reduce the wear and tear on these vehicles. Examples include robots in robot-simulated shooting games, or drones used in drone-simulated aerial combat.

[0099] This invention utilizes fluorescent materials with different emission wavelengths at different locations on the same shooting target 4. Based on these different emission wavelengths, it determines whether the target has been hit, making elimination decisions for hit targets, or determining whether movement is restricted due to partial injury to the participant or damage to the unmanned vehicle. This increases the realism of the simulated shooting game or competition, enhancing the participant's sense of realism.
