The liquid is sprayed downward from the nozzle 411a and is recovered in the recovery part 420a located below. Although FIG. 3A shows a configuration in which liquid is sprayed from top to bottom, liquid may be sprayed from bottom to top, left to right, right to left, or any combination thereof, May be simultaneously injected. The recovery unit 420a is configured to store the liquid by a water tank or a water tank. The liquid stored in the recovery section 420a may include not only those recovered after being jetted from the nozzle 411a but also those supplied from an external separate source (not shown). The liquid stored in the recovery section 420a is supplied to the spray section 410a by the supply section 430a. The supply part 430a includes a pump 431a and a supply pipe 432a and the liquid stored in the recovery part 420a is moved along the supply pipe 432a by the action of the pump 431a to be supplied to the spray part 410a . The liquid screen 400a can supply or shut off the liquid to the jetting section 410a by controlling whether the pump 431a is turned on or off via a separate control module so that liquid jetting from the jetting section 410a So that the screen membrane S can be formed by spraying the liquid only when necessary.

The liquid screen 400a described above is merely an example of one of various liquid screens applicable to the present invention, and the screen of the present invention is not limited to the liquid screen 400a described above.

When the liquid screen 400a as described above is used for screen golf, when the hit golf ball hit by the user hits the liquid screen 400a, the golf ball passes through the liquid screen 400a and moves to the rear of the liquid screen 400a do. In the conventional case, since the golf ball bounces on the screen and is scattered on the floor after being hit on the screen, there is a problem that the play environment is not pleasant as the play progresses. When the liquid screen 400a is used, Can be solved.

FIG. 4A is a view showing a configuration of a mist screen as an example of a screen that can be used in the virtual golf simulation apparatus of FIG. 1, and FIG. 4B is a diagram showing a detailed structure of a jetting portion of the mist screen of FIG. 4A.

Referring to FIG. 4A, a screen 400b according to the present embodiment includes a spraying unit 410b, a collecting unit 420b, and a supplying unit 430b, which displays an image through a screen membrane using fog. The jetting part 410b is for spraying mist and includes a jetting tube and a plurality of jetting ports 411b formed in the jetting tube 411b and a guide 412b protruding downward 4b). The guide 412b may be formed by inserting a spraying piece having a rounded shape into the discharge port 411b or fixing it to the discharge port 411b in order to guide the mist sprayed from the discharge port 411b. The shape and structure of the guide 412b are not limited to those shown in Fig. 4B, and the guide 412b may be omitted.

The fog screen 400b described above is merely an example of one of various fog screens applicable to the present invention, and the screen of the present invention is not limited to the fog screen 400b described above.

When the above-described fog screen 400b is used for screen golf, when the golf ball hit by the user hits the fog screen 400b, the golf ball passes through the fog screen 400b and moves to the rear of the fog screen 400b do. In the conventional case, since the golf ball bounces on the screen and is scattered on the floor after being hit on the screen, there is a problem that the play environment is not pleasant as the play progresses. When the fog screen 400b is used, Can be solved. In addition, the fog screen 400b can display a precise image as compared with a conventional screen, and can be installed easily in a narrow space.

In addition to the use of a liquid or fog screen, the virtual golf simulation apparatus can give a feeling that the golf ball hit by the user is sucked into the screen and displayed after the golf ball hits the screen. Hereinafter, A specific operation method for this will be described.

5 to 9 are views for explaining examples of various operation methods of the virtual golf simulation apparatus of FIG. Figs. 5A to 5C show the first operation method, Figs. 6A to 6C show the second operation method, Figs. 7A to 7E show the third operation method, Figs. 8A to 8C show the fourth operation method And Figs. 9A to 9C show the fifth operation mode.

<First Operation Method>

Referring to FIG. 5A, a screen golf player 1 (hereinafter, referred to as a screen golfer) 1 has a golf club 2 and is located on the striking plate 10, ) Has an actual golf ball (RB). For reference, in relation to the golf ball referred to in this specification, in order to avoid confusion between a real golf ball actually hit by a screen golfer and a virtual golf ball displayed on the screen 400, In the golf ball and virtual golf ball, different reference numerals (actual golf ball: RB, virtual golf ball: VB) are indicated.

In FIG. 5A, the golf club 2 is impacted on an actual golf ball RB, which represents a moment when the screen golfer 1 is about to hit or just hit to make a tee off.

Referring to Figs. 5B and 5C, the screen golfer 1 completes the swing, and the hit golf ball RB advances toward the front to collide with the screen 400. [ When an actual golf ball RB collides with the screen 400, a virtual golf ball VB is displayed on the screen 400 after collision. For reference, if a virtual golf ball VB is displayed at the same time as a collision, a virtual golf ball VB may be displayed with a collision with the naked eye. In the virtual golf simulation apparatus, a virtual golf ball (VB) may be selectively displayed simultaneously with or immediately after the collision. In this case, the virtual golf ball VB ) Or displaying a virtual golf ball (VB) immediately after the collision. Therefore, in the present specification, what is described as 'after collision' may be considered to include the concept of 'collision and simultaneous' in some cases.

The virtual golf ball VB is not displayed on the screen 400 immediately after the actual golf ball RB is struck (refer to FIG. 5B), and the actual golf ball RB is not displayed on the screen 400 The virtual golf ball VB is displayed on the screen 400 as soon as it collides with the virtual golf ball VB.

In other words, for convenience of explanation, a point in time at which an actual golf ball RB is hit is referred to as a first point of time T1, and an actual golf ball RB flies from the first point of time T1 to collide with the screen 400 (T2 = T1 + DELTA T) at which the actual golf ball RB collides with the screen 400 (or the point immediately after the collision) is referred to as a second time point T2 (T1,? T, and T2 are used in the same manner in other embodiments to be described below), the operational feature according to this embodiment is that the virtual golf ball VB is displayed on the screen 400 during the flight time? Is not displayed.

The effects of the above operation characteristics are as follows.

Screen golf can be seen as a mixture of real world and virtual world. That is, the screen golfer 1 actually hits the actual golf ball RB in the field of the outdoor and there is no difference in behavior, which can be regarded as a real world. On the other hand, the movement of the golf ball after the hitting is regarded as a virtual world in that it is not caused by the actual golf ball RB but by the virtual golf ball VB in the screen 400. If a virtual golf ball VB is displayed on the screen 400 during the flight time ΔT, the screen golfer 1 can determine how the actual golf ball RB will hit the actual golf ball RB It becomes indifferent to the movement and only focuses on the movement of the virtual golf ball VB displayed on the screen 400. That is, interest of the screen golfer 1 is suddenly changed from the real world to the virtual world around the moment of hitting the actual golf ball RB. As described above, when the interest of the screen golfer 1 is suddenly changed, the real world and the virtual world are disconnected from each other and the gap becomes large. Due to this gap, in the viewpoint of the screen golfer 1, It is difficult to feel the reality that you are playing.

However, if a virtual golf ball VB is not displayed on the screen 400 during the flight time? T as in the present embodiment, the screen golfer 1 can not see the actual golf ball RB even after hitting the actual golf ball RB And the actual golf ball RB collides with the screen 400, the eye line is naturally moved from the moment to the screen 400, Attention is paid to the movement of the virtual golf ball VB displayed on the display unit 400. [ As a result, the interest of the screen golfer 1 is naturally connected from the real world to the virtual world, so that the gap between the real world and the virtual world is reduced, and as a screen golfer 1, the reality You can feel strong.

Particularly, since the transmissive screen is used as the screen 400 according to the present embodiment, as shown in FIG. 5C, after the actual golf ball RB impacts the screen 400, it passes through the screen 400 And goes away from the screen 400 to disappear from the field of view of the screen golfer 1. In the case of using the above-described first operating mode while using the conventional screen, the golf ball bounces after colliding with the screen and remains in the field of view of the user. On the other hand, when the transmissive screen 400 is used, Since the virtual golf ball VB is displayed on the screen 400 while the golf ball RB collides with the screen 400 and the virtual golf ball VB is displayed on the screen 400, While being sucked into the screen 400 and displayed as a virtual golf ball (VB).

According to this operation method, since the virtual golf ball VB starts to be displayed after the actual golf ball RB hit the screen 400, the actual golf ball RB collides with the screen 400 It is necessary to detect that Therefore, it may be necessary to further detect a sensor (not shown in the figure) to detect that the actual golf ball RB collides with the screen 400. As the sensing sensor, a sensor that visually senses whether or not an actual golf ball (RB) collides with the screen 400 using a camera or the like may be used. Such a sensor can additionally detect not only whether the golf ball is in a collision, but also a colliding position and a direction in which the golf ball RB moves in the event of a collision, and such additional sensing information may be used in another operation method described later. However, it is also possible to calculate the information without using the sensor. For example, in order to simulate the trajectory of a virtual golf ball RB after the screen golfer 1 hits an actual golf ball RB, it senses the state of an actual golf ball RB such as a speed, a spin, From the sensed information, it is possible to calculate a point of time when an actual golf ball RB collides with the screen 400, a collision direction, a collision position, and the like.

This operation mode is based on the assumption that an actual golf ball RB will collide with the screen 400. If the golf ball RB hit by the screen golfer 1 does not hit the screen 400, The conventional method can be applied instead of applying the method.

<Second Operation Method>

Referring to FIG. 6A, at the first time point T1, the screen golfer 1 strikes an actual golf ball RB. Compared with FIG. 5A, there is a difference in that the actual golf ball RB lies directly on the strike mat 11, rather than the auto tee (see reference numeral 12 in FIG. 5A). In general, when tee-off is performed, the golf ball is struck by an actual golf ball RB in the auto tee, but strikes an actual golf ball RB on the striking mat 11 when the tee off is not performed. Compared with FIG. 5A, there is also a difference in that a virtual golf ball VB is displayed on the screen 400. FIG. 6A shows a state in which a golf course is already proceeding after tee-off. Therefore, the virtual golf ball VB can be displayed in various areas on a virtual golf course , Rough, bunker, etc.). As shown in FIG. 6A, when a virtual golf ball VB is displayed on the screen 400, the screen golfer 1 clearly displays the position of the golf ball VB on the current virtual golf course before hitting it .

6B, immediately after the screen golfer 1 hits the actual golf ball RB, the virtual golf ball VB disappears from the screen 400, and from the first point of time Tl to the actual golf ball VB, The virtual golf ball VB is not displayed on the screen 400 during the flight time [Delta] T until the ball RB collides with the screen 400. [

6C, when an actual golf ball RB impacts the screen 400, the actual golf ball RB passes through the screen 400, and simultaneously with the colliding second point of time T2, Or immediately after the second time point T2, the virtual golf ball VB is displayed on the screen 400 again. This is the same as the first operation mode shown in Fig. 5C.

According to the present embodiment, a virtual golf ball VB is displayed on the screen 400 before the actual golf ball RB is hit so that the virtual golf ball VB is displayed before the screen golfer 1 is hit It is possible to determine whether or not it is located. In addition, since the virtual golf ball VB is not displayed on the screen 400 during the flight time AT from the moment the hit is made, the screen golfer 1 immediately turns on the screen 400, Golf balls (RB) to attract attention. As a result, similar to the case of the first operation method, it is possible to reduce the gap between the real world and the virtual world and to give a reality as if playing in the outdoor field.

<Third Operation Method>

Referring to FIGS. 7A and 7B, the operation during the first time T1 and the flight time T is the same as the second operation. That is, the virtual golf ball VB is displayed on the screen 400 at the first point in time T1, but the virtual golf ball VB disappears from the screen 400 after the first point in time T1, DELTA T). The operation during the first time point T1 and the flight time period T is similar to the first operation mode so that the virtual golf ball VB is not displayed on the screen 400 from the first time point T1 .

Referring to FIG. 7C, when an actual golf ball RB impacts the screen 400, the actual golf ball RB passes through the screen 400, and simultaneously with the colliding second point of time T2 Or immediately after the second time point T2, the virtual golf ball VB is displayed on the screen 400 again. Here, the virtual golf ball VB starts to be displayed from the same point where the actual golf ball RB hit the screen 400 (in FIG. 7C, the two golf balls RB and VB overlap each other) So that the position of the virtual golf ball VB and the position of the actual golf ball RB do not completely coincide with each other so as to prevent any one from being hidden by the other.

As such, when a virtual golf ball VB appears on the screen 400 at the point where the actual golf ball RB hit the screen 400, an actual golf ball RB is displayed on the screen 400 And then sucked into the screen 400 to give a feeling of being displayed as a virtual golf ball VB. As a result, the gap between the real world and the virtual world is further reduced, making it possible to get a strong impression that is actually playing outdoors and maximize the reality.

7D and 7E each show a modification of the third operating mode.

Referring to FIG. 7D, at the second time point T2, the virtual golf ball VB starts to be displayed on the screen 400 from the vicinity of the point where the actual golf ball RB hit the screen 400. [ In order to give the impression that the actual golf ball RB is sucked into the screen 400 after collision with the screen 400, it is preferable that the virtual golf ball VB is displayed from the same point as the point of collision , It may not be easy to exactly match the collision point of the actual golf ball RB with the display start point of the virtual golf ball VB. Since the size of the golf ball is not large, even if a virtual golf ball VB is displayed near the collision point of the actual golf ball RB, even if the human eye correctly recognizes that the collision point and the display start point are different Is difficult. Thus, within a range where the person with normal vision can not recognize that the collision point and the display start point are different, a virtual golf ball VB is displayed near the collision point of the actual golf ball RB . As shown in FIG. 7D, if the radius of an actual golf ball RB is represented by 'R', there is a variation in the range where the collision point and the display start point are not recognized. It is preferable that the center of the golf ball RB is within a range of approximately 5R from the center of the golf ball RB, and more preferably within a range of approximately 3R.

Referring to FIG. 7E, the background screen of the screen 400 may be viewed as a horizontal or vertical movement starting from the second time point T2. The virtual golf ball VB at the second time point T2 in the third operating mode is displayed on the screen 400 from the point where the actual golf ball RB hit the screen 400 or from the vicinity of the point of collision Start. However, since the trajectory of the virtual golf ball VB is determined by the simulation at the control unit (see reference numeral 210 in FIG. 2), the starting position at which the virtual golf ball VB starts to be displayed is Is the start position of the reference point. The position at which the simulated locus starts (hereinafter referred to as a 'start position') and the position at which an actual golf ball RB collides with the screen 400 (hereinafter, referred to as a 'collision position') may be inconsistent. In this case, in order to match the start position and the collision position, the collision position must be moved to the start position or the start position must be moved to the collision position. However, moving the collision position to the starting position is physically impossible. If the player strikes the actual golf ball RB, the actual golf ball RB moves along the predetermined trajectory and meets the screen 400, and since this point becomes the collision position, And it can not be arbitrarily changed. Since the start position is determined according to the simulated locus in the control unit 210, it can not be arbitrarily changed. 7E, when the background screen of the screen 400 is moved, the position where the virtual golf ball VB starts to be displayed on the screen 400 is determined by the actual golf ball RB on the screen 400 to be collided with each other.

Specifically, as shown in (I) of FIG. 7E, in the state before the background screen of the screen 400 is moved, the start position and the collision position are shifted by 'X' in the horizontal direction and 'Y' The start position and the collision position can be matched by moving the background screen of the screen 400 by 'X' in the horizontal direction and by 'Y' in the vertical direction, as shown in (II) of FIG. 5E The virtual golf ball VB and the actual golf ball RB (VB) are overlapped with each other in order to prevent one of the two golf balls RB and VB from overlapping with each other, ) Are not completely coincident with each other).

As described above, this modified example shows an operation method of matching the collision position and the start position by vertically moving or horizontally moving the background screen displayed on the screen 400 or simultaneously performing vertical movement and horizontal movement.

&Lt; Fourth operation method &

8A and 8B, the operation during the first time point T1 and the flight time interval? T is the same as the second operation mode. That is, the virtual golf ball VB is displayed on the screen 400 at the first time point T1, but after the first time point T1, the virtual golf ball VB disappears from the screen 400, DELTA T). Here, the operation during the first time point T1 and the flight time period? T is made similar to the first operation mode so that the virtual golf ball VB is not displayed on the screen 400 from the first time point T1 .

8C, a virtual golf ball VB (not shown) is displayed on the screen 400 at a second time point T2 at which an actual golf ball RB collides with the screen 400 or immediately after the second time point T2. Is displayed and the angle at which the background image is viewed on the screen 400 is changed so that the actual golf ball RB corresponds to the direction in which the golf ball RB collides with the screen 400. [

The direction in which the actual golf ball RB strikes the screen 400 and the moving direction of the virtual golf ball VB displayed on the screen 400 are largely different from each other as shown in Fig. The screen golfer 1 may be viewed as unnatural as if the actual golf ball RB is sucked into the screen 400 and suddenly the direction is refracted. In order to prevent such unnaturalness, the direction in which the actual golf ball RB strikes the screen 400 and the direction in which the virtual golf ball VB displayed on the screen 400 moves must coincide with each other. However, since the actual movement of the golf ball RB is determined by the stroke of the screen golfer 1, the direction in which the actual golf ball RB hits the screen 400 can not be arbitrarily changed. The virtual golf ball VB can not arbitrarily change the moving direction on the screen 400. However, as shown in (II) of FIG. 8C, when the background screen is rotated on the screen 400, The same effect as changing the direction in which the virtual golf ball VB is moved on the screen 400 occurs and consequently the actual golf ball RB collides with the screen 400 And the direction in which the virtual golf ball VB displayed on the screen 400 moves.

<Fifth operation method>

This method of operation relates to how to simulate and calculate the trajectory of an imaginary golf ball VB displayed on the screen 400, which is somewhat different in nature from the previous operation method. This operation mode may be used alone or in combination with at least any one of the first to fourth modes of operation, and FIG. 9 shows an example of being combined with the second mode of operation.

Referring to FIGS. 9A and 9B, the operation during the first time point T1 and the flight time interval? T is the same as the second operation method. That is, the virtual golf ball VB is displayed on the screen 400 at the first time point T1, but after the first time point T1, the virtual golf ball VB disappears from the screen 400, DELTA T). The operation during the first time point T1 and the flight time period T is similar to the first operation mode so that the virtual golf ball VB is not displayed on the screen 400 from the first time point T1 It does not matter.

9C, a virtual golf ball VB is displayed on the screen 400 at a second time point T2 at which an actual golf ball RB collides with the screen 400 or immediately after the second time point T2. Is displayed. A feature of this method of operation lies in the trajectory of the virtual golf ball VB displayed on screen 400. [ Specifically, when the actual golf ball RB is hit at the first time point T1 and the trajectory S for the virtual golf ball VB is calculated as a result of the simulation based on the batting result, What is actually displayed on the screen 400 in the trajectory S is only for the trajectory S2 from the predetermined time after excluding the trajectory S1 from the first time point T1 until a predetermined time elapses . For example, the predetermined time may be a flight time T before the actual golf ball RB hits the screen 400. In this case, the screen 400 is displayed immediately after the second time point T2 Only the locus S2 is displayed.

Considering that the trajectory S1 during the flight period DELTA T in the simulated overall trajectory S corresponds to the trajectory of the actual golf ball RB from the hit point to the flight to the screen 400, By omitting the trajectory S1 and not displaying it, it can be seen that the omitted trajectory S1 is replaced with the actual trajectory shown until the actual golf ball RBs fly to the screen 400. [ Therefore, the actual trajectory of the golf ball RB is displayed outside the screen 400 and the trajectory S2 is represented by the virtual golf ball VB in the screen 400. As a result, the movement of the actual golf ball RB is naturally connected to the movement of the virtual golf ball VB on the screen 400, so that in the actual golf ball RB and the virtual golf ball VB So that it is possible to maximize the feeling that the actual golf ball RB is sucked into the screen 400 and the feeling actually being played outdoors.

Particularly, since the transmissive screen is used as the screen 400 according to the present embodiment, as shown in FIG. 9C, after the actual golf ball RB impacts the screen 400, the screen 400 is passed And goes away from the screen 400 to disappear from the field of view of the screen golfer 1. In the case of applying the above-described fifth operating mode while using a conventional screen, the golf ball bounces after colliding with the screen and remains in the field of view of the user. On the other hand, when the transmissive screen 400 is used, Since the virtual golf ball VB is displayed on the screen 400 while the golf ball RB collides with the screen 400 and the actual golf ball RB collides with the screen 400, 400) to give a very strong feeling of being displayed as a virtual golf ball (VB).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, will be. For example, the first to fifth operating modes are not used separately, but they can be used in combination. For example, an operation method (refer to FIG. 7E and related description) for moving the background screen to match the position where the actual golf ball collides with the start position where the virtual golf ball is displayed, (See FIG. 8C and related description) of rotating the background screen to match the direction in which the golf ball of the golf ball moves on the screen.

Accordingly, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
