Description

Augmented Reality Shooting Simulator [0002]

The present invention relates to an augmented reality shooting simulator, and more particularly, to an augmented reality shooting simulator that allows a reaction force to be generated such as a shooting of an actual gun during a shooting process of a simulated gun to increase the sense of presence.

In recent years, with the development of multimedia technology and computer programming, the virtual experience of simulating the actual situation and experiencing it in the actual situation, have.

Particularly, in the virtual space simulating the actual situation, such as aircraft training and indoor driving practice are performed in the virtual space. Also, in the sports area, the training of the athletes is performed in the virtual space, have.

On the other hand, in the field of entertainment, multimedia experience and computer technology experience situations that can not be produced in a real situation through virtual experience.

In this way, the virtual reality experience by the simulator is used to cultivate the ability to cope properly when actual situation occurs by actually experiencing situations which are difficult to direct in actual situation.

In recent years, it has become possible to actively cope with real situations by using various multimedia and computer technologies to simulate real situations and to create various environments that can be practically generated in a virtual space, A video shooting training system has been researched and developed so that the field experience and the shooting skill can be polished.

In Korea, only authorized persons, such as police officers and soldiers, are allowed to use firearms.

Therefore, they are only allowed to use firearms in authorized areas, and firearms are limited to the use of firearms on fixed targets several times a year.

In addition to the standardized shooting training using guns for fixed targets as well as the lack of opportunities for training, if the use of firearms is actually permitted, There is a problem that I can harm innocent people.

In addition, when actual shooting training is performed, various complaints by the residents near the training site and temporal, spatial, and material constraints cause a problem in constructing an efficient training system.

In order to solve such a problem, a need has arisen for a video shooting training system as described above.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 2000-0063143 (published on November 6, 2000) discloses a technique in which, as triggered by a trigger of a simulated pistol as known in the art, A piston which is fixed to the interior of the simulated pistol body and which is open at the front of the muzzle and closed at the rear by a rear wall, a piston installed to reciprocate inside the cylinder, and a piston which is coupled to the opening of the cylinder, And a hose connected to an external air pump to provide a high pressure.

Accordingly, a simulated pistol reaction force generation device realizing a recoil impact by supplying high-pressure air of the air pump to the cylinder by the controller receiving the trigger signal makes the piston in the cylinder strike the cylinder rear wall by the air pressure.

That is, when the trigger of the firearm is pulled, a signal is transmitted to the controller to open the valve of the air pump to supply high-pressure air into the cylinder, and push the piston to the rear of the gun promptly according to the pressure. There is disclosed a reaction force generating apparatus technique which is configured to realize a reaction of impact and thereby to feel a sense of actually shooting.

However, such a simulation gun has been improved to some extent by the technique of the reaction force of the firearm such as the back reaction force through the reaction force generating device described above, but it is somewhat different from the actual firearm, There is a problem that it is weak, and there is a problem that it can not provide a reaction force of a firearm in accordance with a precise triggering time.

Particularly, when a plurality of firearms are simultaneously used (triggered) or when continuous shooting is performed, the capacity and the charging pressure of the air pump are not constantly controlled and the uniform reaction force can not be provided, .

As shown in the drawing, the augmented reality shooting simulator of the present invention includes a compressor 300 for compressing air, a pressure tank 310 for filling air compressed by the compressor 300, And a reaction force generating means (200) installed in the pressure tank (310) for generating a reaction force by compressed air supplied from the pressure tank (310).

1, the compressed air in the compressor 300 is charged into the pressure tank 310 through the first distribution line 410 and the compressed air charged in the pressure tank 310 is supplied to the branch line 420 The compressed air having passed through the electromagnetic solenoid valve 330 is moved to the electromagnetic reducing valve 320 through the second flow line 430 and then flows to the third flow line 440 Force generating means 200 to generate the reaction force of the trigger 120 of the simulated gun 1000, that is, the reaction force when shooting. Here, the structure of the reaction force generating means 200 and the description of the reaction force generation will be described later.

The compressor 300 is an air pump for compressing air, and the compressed air is charged into a pressure tank 310 connected to the first distribution line 410. The pressure tank 310 is formed of a pressure vessel having a predetermined inner volume so that a certain amount of air can be filled therein. When a predetermined amount of compressed air is charged by the pressure tank 310, a plurality of simulated guns 1000 are simultaneously fired A sufficient amount of compressed air is provided, and compressed air can be maintained at a constant pressure even when continuous shooting is performed.

The branch line 420 is connected to the outlet of the pressure tank 310 and the compressed air discharged from the pressure tank 310 is moved to the electronic solenoid valve 330 side via the branch line 420.

The electronic solenoid valve 330 is a kind of electronic opening / closing valve whose operation to open or close the flow path is controlled by an electric signal. The electromagnetic solenoid valve 330 opens the flow path by a signal according to the operation of the trigger 120 of the simulated gun 1000, The compressed air is supplied to the reaction force generating means 200 of the simulated gun 1000, so that a reaction force is generated when the compressed air is fired.

The compressed air circulated through the electromagnetic solenoid valve 330 is adjusted to a predetermined pressure by the electromagnetic reducing valve 320 through the second flow line 430 and then circulated to the reaction force generating means 200 side, The ducing valve 320 is a pressure regulating valve for allowing the circulating compressed air to flow at a predetermined pressure. The pressure regulating valve maintains the pressure of the compressed air supplied to the reaction force generating means 200 constant so as to generate a uniform reaction force .

Although only one branch line 420 may be formed, as shown in the figure, a plurality of mock firearms 1000 may be installed.

When the plurality of simulated guns 1000 are installed and the simulated guns 1000 are shot simultaneously, the supply of the compressed air is smoothly maintained by the pressure tank 310, and each of the simulated guns 1000 Since the pressure of the compressed air introduced into the reaction force generating means 200 is constantly controlled by the installed electronic reducing valve 320, a uniform reaction force is always generated at the time of shooting and a constant reaction force is provided at the time of continuous shooting You can get the same realism as shooting using real firearms.

2 to 4, the reaction force generating means 200 includes a cylinder 210 fixed inside the simulated gun 1000, a front cap 220 and a rear cap 230 which hermetically seal both ends of the cylinder 2100 And a piston 240 for generating a reaction force toward the buttocks 110 of the simulated gun 1000 by hitting the rear cap 230 in a reciprocating motion in the cylinder 210.

Only the structure in which a reaction force is generated toward the buttocks 110 of the simulated gun 1000 by hitting the rear cap 230 in the process of moving backward by the compressed air supplied to the piston 240 will be described, 240 may be moved forward to strike the front cap 220, so that a reaction force may be generated on the side of the muzzle.

The front cap 220 closes one side of the cylinder 210 to form one side pressure chamber S1 between the pistons 240. Compressed air is supplied from the electromagnetic reducing valve 320 to the front cap 220 And a rear cap 230 for sealing the other side of the cylinder 210 and forming the other side pressure chamber S2 between the pistons 240 is provided at the opposite side of the front cap 220 .

The piston 240 maintains a state in which the piston 240 is urged toward the front cap 220 by the coil spring 250 installed in the interior of the piston 240. However, The rear cap 230 is hit in the process of moving.

The hitting force generated by the piston 240 hitting the rear cap 230 has a very similar effect to the reaction force that the gun is pushed toward the buttocks when the actual firearm is fired so that the firing of the simulated gun 1000 Realistic feelings such as shooting a real firearm are reproduced as the reaction force like real firearm is implemented.

A piezoelectric impact sensor 260 may be installed in front of the rear cap 230. The piezoelectric impact sensor 260 generates an electrical signal when an impact is generated. When the piston 240 hits the rear cap 230, the piezoelectric impact sensor 260 transmits an electrical signal corresponding to the impact to the controller 700.

The control unit 700 calculates the amount of impact according to the electric signal received from the piezoelectric impact sensor 260. When the calculated amount of impact does not reach a predetermined set value, the control unit 700 sets the set pressure of the electromagnetic- So that the pressure of the compressed air supplied to the reaction force generating means 200 is increased so that the reaction force is increased.

On the contrary, when the amount of impact due to the electric signal received from the piezoelectric impact sensor 260 exceeds a predetermined set value, the control unit 700 sets the set pressure of the electromagnetic reducing valve 320 to a low level, So that the reaction force is reduced.

When the measured impact amount does not reach a preset value, that is, when the reaction force is not met, the set pressure of the electromagnetic reducing valve 320 is increased and the reaction force generating means The pressure of the compressed air supplied to the piston 200 is increased so that the reaction force is increased. When the impact amount of the piston 240 exceeds a predetermined value, that is, when the reaction force is greater than the reference, So that the reaction force is reduced in real time by lowering the set pressure of the combustion chamber 320, so that the shooter can always feel a uniform reaction force.

In addition, the augmented reality shooting simulator of the present invention not only imposes a reaction force that pushes the simulated gun 1000 backward while shooting, but also enhances the sense of presence at the time of shooting by allowing the gun to be heard. Hereinafter, muzzle shooting will be described in more detail.

Referring to FIG. 3, a spraying unit 600 for discharging compressed air to the outside is installed at the lower end of the shooting gun 100 on the side of the shooting gun 100. The spraying means 600 is a nozzle for spraying the compressed air to the outside, and the muzzle is lifted up by the compressed air thus sprayed, thereby increasing the sense of presence.

The injection means 600 communicates with the other side pressure chamber S2 of the reaction force generating means 200 through the compressed air discharge line 500.

As the piston 240 is moved toward the rear cap 230, the air in the other pressure chamber S2 is momentarily compressed and the compressed air is injected into the lower end of the barrel 100 through the compressed air discharge line 500. [ As a result, the muzzle is heard.

FIG. 4 shows another embodiment of the present invention. In the lower end of the gun 100, a spraying unit 600 for discharging compressed air to the outside is installed. The spraying means 600 is a nozzle for spraying the compressed air to the outside, and the muzzle is lifted up by the compressed air thus injected, thereby further enhancing the sense of presence.

The injection means 600 is connected to the compressed air bypass line 550 branched from the compressed air circulation line 400 so that a part of the compressed air flows in the course of the compressed air being circulated toward the reaction force generating means 200 And is injected through the compressed air bypass line 550 to the lower end of the gun column 100. As a result, when the muzzle is lifted up, the reaction force is generated, and the shooter can feel the reaction force and the muzzle simultaneously.

At this time, the compressed air bypass line 550 may be branched from any of the compressed air distribution lines, but branched from the third distribution line 440 connecting the electromagnetic reducing valve 320 and the reaction force generating means 200 More preferable.

The third distribution line 440 is provided with the compressed air at the same time as the reaction force generating means 200 and the muzzle lifting means 600 as the last formed flow path of the compressed air introduced into the reaction force generating means 200 There is an effect that the reaction force and the muzzle lifting can occur at the same time.

Hereinafter, the process of generating a reaction force and a bullet shape when shooting is described.

The shooter manipulates the trigger 120 to aim the target ahead and fire the trigger 120. At this time, the motion of the trigger 120 is converted into an electrical signal by the sensor 130 connected to the trigger 120 and transmitted to the controller 700 .

The control unit 700 opens the electronic solenoid valve 330 according to the operation signal of the trigger 120 to allow the compressed air to flow to the reaction force generating means 200. [ The compressed air thus circulated is adjusted to a predetermined pressure through the electromagnetic reducing valve 320 having the flow pressure set therein, and then introduced into the reaction force generating means 200 to generate a reaction force.

As described above, the reaction force is generated by pushing the piston 240 backward by the supplied compressed air and striking the rear cap 230. In this process, the piston 240 is instantaneously compressed The compressed air is discharged to the lower end of the total heat 100 through the compressed air discharge line 500 connecting the other side compression chamber S2 and the injection means 600 installed at the lower end of the total heat 100,

The compressed air can be circulated by the compressed air bypass line 550 branched from the third distribution line 440 in the injection means 600.

The impact generated by the piston 240 during the reaction force generated by the reaction force generating means 200 is sensed by the piezoelectric impact sensor 260 and output as an electrical signal, .

The control unit 700 calculates the amount of impact based on the received electric signal, determines that the reaction force is low when the calculated impact amount is smaller than a predetermined value, and adjusts the setting pressure of the electromagnetic type reducing valve 320 to a higher value It is determined that the reaction force is greatly generated when the impact amount is larger than a predetermined value, and the reaction force is controlled to be increased by setting the set pressure of the electromagnetic type reducing valve 320 to be higher. This allows the shooter to always feel a uniform reaction force.

Here, the control unit 700 may adjust the set pressure of the electromagnetic reducing valve 320 and the amount of the shock received from the piezoelectric impact sensor 260 according to the user's request so that the reaction force can be adjusted according to the user's request.

Accordingly, the reaction force can be adjusted according to the user's demand and the simulation situation.
