FIG. 2 is a diagram showing a schematic structure of a screen baseball system using a transmissive screen according to an embodiment of the present invention, and FIG. 3 is a block diagram for explaining a relation between main components of the screen baseball system of FIG. 2 .

2 and 3, the screen baseball system 100 includes a ball pitching unit 110, a control unit 120, a video output unit 130, and a screen 140. In addition, the screen baseball system 100 is provided with a striking plate 101 on which a user is positioned to strike, and various sensing devices for sensing a ball hit by a user are provided, though they are not shown in the drawing. The sensing device is for sensing the overall physical state of the hit ball by detecting the movement of the ball hit by the user, and the detected information is transmitted to the controller 120 and used for the operation of the controller 120 have. As the sensing device, any sensing means such as a camera or a sensing sensor may be used, and the camera, the sensing sensor, etc. may be used alone or in combination, or may be used alone or in multiple units.

The striking plate 101 is spaced a predetermined distance from the screen 140. The distance between the pitcher and the catcher in the actual baseball is 18.44 m, and the distance between the striking plate 101 and the screen 140 can be set to about 18 m even in the screen baseball. However, in many cases, the screen baseball often lacks a space for installation, so that the distance between the striking plate 101 and the screen 140 is often shorter than 18 m. The surface of the screen 140 facing the striking plate 101 is referred to as a 'front' for convenience, and a ball pitching unit 110 is provided on a 'rear surface' of the screen 140. The ball pitching unit 110 fires and pitches the baseball ball so that a user located at the striking plate 101 can strike the ball. The specific structure of the ball pitching unit 110 will be described later with reference to FIG. 6A.

The control unit 120 is responsible for various operations and controls necessary for the operation of the screen baseball system 100. For example, if the user hits the pitching ball, the control unit 120 receives overall status information about the hit ball from the sensing device, (Ground ball, fly, hits, home run, etc.) based on the baseball ball. The control unit 120 may include an input unit 121 and a database 122. The input unit 121 receives a variety of information from a user, and may be a keyboard, a mouse, or the like. In screen baseball, a team of two or more players is divided into two teams, each team competes to win or lose by doing preliminary (second attack of each innings) and backhand (attack of each innings). In such a game, It is necessary to input the nickname of the user, the name of the team, and the like. The database 122 stores information necessary for calculating the batting result of the hit ball of the user or information about the baseball related image to be displayed on the screen 140. [

The video image output device 130 displays images such as a pitcher pitch, a virtual ball displayed on the screen 140 corresponding to the ball hit by the user, a defender who defends the virtual ball, A display device such as a beam projector can be used. The screen 140 displays the image projected by the image output device 130 and displays it to the user. 2, when the image display device 130 and the striking plate 101 are disposed opposite to each other with the screen 140 therebetween, the screen 140 becomes a 'transmission type' screen, and the striking plate 101 is viewed from the image output device 130 on the opposite side of the image output device 130. 2, the screen 140 may be a 'reflective' screen if the image output device 130 and the striking plate 101 are disposed on the same side with the screen 140 therebetween.

According to an embodiment of the present invention, a 'transmissive screen' can be used as the screen 140, in which a ball pitched in the ball pitching unit 110 can pass through the screen 140 as it is. In a conventional screen, even though the pitched ball passed through the screen through the pitching hole, in this embodiment, the ball differs from the conventional screen in that the ball can pass through the screen 140 even though there is no separate pitching hole have. Since there is no separate pitching hole, it is possible to solve the problem of omitting the image displayed on the screen in the pitching hole as in the conventional art. Therefore, it is possible to improve the interest in the screen baseball game without undermining the feeling of immersion in the displayed image. The specific structure of the screen 140 through which the baseball ball can pass without pitching holes will be described later with reference to Figs. 4 and 5. Fig.

Although not shown in FIGS. 2 and 3, the screen baseball system 100 may further include a voice processing unit. The voice processing unit can guide the user to the progress of the game and play various sound effects according to the progress of the game.

4A, a screen 140a according to the present embodiment is a liquid screen for displaying an image through a screen membrane S using liquid, and includes a jetting section 10a, a collecting section 20a, and a supplying section 30a . The jetting section 10a is configured such that a plurality of nozzles 11a are formed in the jetting tube (see FIG. 4B). The liquid passing through the jetting tube at a high pressure is jetted in a bubble state through the nozzle 11a, To form a screen membrane S. [0051] As shown in FIG. The liquid is sprayed downward from the nozzle 11a and is recovered in the collection part 20a located at the lower side. Although FIG. 4A shows a configuration in which liquid is injected from top to bottom, liquid may be ejected from bottom to top, left to right, right to left, or any combination thereof, May be simultaneously injected. The recovery unit 20a is configured to store liquid by a water tank or a water tank. The liquid stored in the recovery section 20a may include not only the liquid recovered after being sprayed from the nozzle 11a but also the one supplied from an external separate source (not shown). The liquid stored in the recovery section 20a is supplied to the spray section 10a by the supply section 30a. The supply part 30a includes a pump 31a and a supply pipe 32a and the liquid stored in the recovery part 20a is moved along the supply pipe 32a by the action of the pump 31a and supplied to the spray part 10a . The liquid screen 140a can supply or shut off the liquid to the jetting section 10a by controlling whether the pump 31a is turned on or off via a separate control module. As a result, it is possible to form the screen film S by controlling the presence or absence of the liquid jet in the jetting section 10a and spraying the liquid only when desired.

The liquid screen 140a 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 140a described above.

FIG. 5A is a view showing a configuration of a fog screen as an example of a screen that can be used in the screen baseball system of FIG. 2, and FIG. 5B is a view showing a detailed structure of a fog screen of the fog screen of FIG. 5A.

5A, a screen 140b according to the present embodiment is a mist screen for displaying an image through a screen membrane S using fog, and includes a jetting section 10b, a collecting section 20b, a supplying section 30b, . The jetting section 10b is for jetting mist and includes a jetting tube and a plurality of jetting ports 11b formed in the jetting tube and a guide 12b protruding downward from the jetting port 11b 5b). The guide 12b may be formed by inserting a spraying piece having a rounded shape into the discharge port 11b or fixing it to the discharge port 11b in order to guide the mist sprayed from the discharge port 11b. The shape and structure of the guide 12b are not limited to those shown in Fig. 5B, and the guide 12b itself may be omitted. The fog sprayed from the jetting section 10b descends downward to form the screen membrane S and is recovered in the recovery section 20b. A suction fan 21b is provided at one side of the recovery unit 20b so that the mist can be easily recovered from the recovery unit 20b by the suction force formed by the suction fan 21b and then discharged to the outside . The supply portion 30b includes a pump 31b and a supply pipe 32b so that the liquid for forming a mist by the action of the pump 31b is moved from the outside along the supply pipe 32b to be supplied to the spray portion 10b . The liquid may be pumped as high pressure water by the pump 31b and sprayed in the form of mist in the jetting section 10b or by allowing the supply tube 32b to pass through a separate heater A mist may be generated in the heater and may be jetted from the jetting section 10b.

The fog screen 140b described above is merely an example of one of various fog screens that can be applied to the present invention, and the screen of the present invention is not limited to the fog screen 140b described above.

If the liquid screen 140a or the fog screen 140b or the like is used for the screen baseball, the baseball ball can freely pass through any area of the screens 140a and 140b. Therefore, a separate pitching hole Is unnecessary. Conventionally, the image displayed on the screen at the portion where the pitching hole is formed has been omitted. However, when the transmissive screen such as the liquid screen 140a or the mist screen 140b is used, such a problem can be completely solved. Particularly, the fog screen 140b has a merit that not only a precise image can be produced as compared with a conventional screen, but also a fog screen 140b can be easily installed in a small space.

FIG. 6A is a diagram showing a structure of a ball pitching unit in the screen baseball system of FIG. 2; FIG.

Referring to FIG. 6A, the ball pitching unit 110 includes a pitching machine 111 and a position adjuster 112. The pitching machine 111 is a part for pitching the baseball ball to the user so that the user can hit the pitching machine 111 and the position adjuster 112 is a part for positioning the pitching machine 111 by placing the pitching machine 111 at the lower end . The pitching machine 111 is provided from the outside so that the ball 1 passing through the inside of the body 111a passes between the two wheels 111b. The two wheels 111b are connected to the center of the motor M so that the two wheels 111b are rotated by the operation of the motor M. When the two wheels 111b rotate, And receives the force from the wheel 111b to fly to the user.

Since the mechanism of the pitching machine has been briefly described above, the mechanism for pitching the baseball in the pitching machine can be applied to any known prior art, so that detailed description is omitted. For example, in addition to the type of mechanism for pitching a baseball ball using a pair of wheels as described above, there are a type using a spring articulated arm mechanism, a pressure type based on a hydraulic or pneumatic type, A pitching machine using a mechanism such as a type that uses a magnetic field or the like may be used.

A connecting rod 111c is attached to the lower end of the body 111a of the pitching machine 111. The connecting rod 111c is connected to the position adjuster 112. [ The position adjuster 112 serves to adjust the position of the pitching machine 111 in the horizontal and vertical directions. Specifically, the position adjuster 112 includes an upper plate 112a, a lower plate 112b, upper and lower plate coupling holes 112c, a base hole 112d, and a guide 112e. The upper plate 112a is coupled to the connecting rod 111c to the upper side and coupled to the lower and upper plate connecting ports 112c to the lower side. The lower plate 112b is coupled to the upper and lower plate coupling holes 112c at the upper side and coupled to the base hole 112d at the lower side. 6A, the upper and lower plate connecting portions 112c are configured to be elongated or contracted in the vertical direction (z direction) so that their heights can be varied. Thus, the distance between the upper plate 112a and the lower plate 112b is Lt; / RTI > As the distance between the upper plate 112a and the lower plate 112b changes, the height (position in the vertical direction) of the pitching machine 111 connected to the linking unit 111c from above the upper plate 112a can be adjusted have. The base sphere 112d is composed of a plurality of pairs and is configured to be able to move along a pair of guides 112e including wheels. The pitching machine 111 placed above the upper plate 112a also moves along the guide 112e as the base tool 112d moves along the guide 112e and the horizontal direction of the pitching machine 111 (x direction) can be adjusted.

With the above structure, the position adjuster 112 can adjust the position of the pitching machine 111 in the vertical direction and the horizontal direction. However, FIG. 6A only shows one of various ways of adjusting the position of the pitching machine 111, and the structure of the position adjuster 112 is not limited to the structure shown here. Although not shown in FIG. 6A, a separate control means for receiving an instruction from the control unit (refer to reference numeral 120 in FIG. 2) and controlling the position adjuster 112 so that the pitching machine 111 is positioned at the indicated position .

FIG. 6B is a view showing a structure of a ball pitching unit as a modification of FIG. 6A. FIG.

Referring to FIG. 6B, in this modified example, the structurally deformed portion is a ball covering means 111d provided near the exit from which the baseball ball is fired. The ball covering means 111d blocks the contact between the ball and the outside in a space on the path through which the ball fired by the pitching machine 111 passes from near the outlet of the pitching machine 111 until it passes substantially through the screen or the screen . The inside of the ball covering means 111d is open so that the ball can pass therethrough, so that the ball cover can be covered from the outside in a predetermined space on the path along which the ball passes. For example, as shown in FIG. 6B, the body portion of the ball covering means 111d may have a structure in which a hollow cylindrical cylinder lies horizontally, and the body portion may include a position adjuster 112, and the like. The material of the ball covering means 111d is not particularly limited, but it is preferable that at least the body portion is made of a transparent material. The body portion is arranged to contact the screen or slightly penetrate the screen so that when the ball passes through the screen, the body is prevented from contacting the liquid constituting the liquid screen. Therefore, it is preferable that the ball covering means 111d is made of a transparent material so as not to be recognized by the user.

In the case where the ball covering means 111d is provided as described above, when the ball pitched by the ball pitching unit 110 passes through the screen, the ball does not touch the screen and is not wetted with water. In the absence of the ball covering means 111d, the ball launched from the ball pitching unit 110 is wetted with water as it passes through the liquid screen. When the wet ball reaches the user, the water bulges to the user and the user feels uncomfortable feeling . In addition, in the case of hitting a ball wet with water, it is preferable that the ball hit by the user is kept as dry as possible, since the feeling of hitting may be different from that of a ball not wetted with water. The same problems can be solved.

FIG. 7 is a view showing a menu for selecting various types of virtual pitchers in the screen baseball system of FIG. 2, and FIG. 8 is a view showing various types of virtual pitchers that can be displayed on the screen in the screen baseball system of FIG. Fig.

As shown in FIG. 7, according to the present embodiment, the user can select a desired type among various types of virtual pitchers to be displayed on the screen. For example, in a real baseball, there is a left-hander and a right-hander depending on which hand is thrown, and the power of the ball may vary according to the height of the pitcher, even if it is the same left-hander (or the same right-hander). In addition, there are various pitching types such as overslope, three-quarter, side arm, under-throw, etc., and the trajectory of the ball may vary depending on this type of pitching. From a user's point of view, depending on whether he is hitting with his right or left hand, he can also select a virtual pitcher appropriately according to his preferred pitching type. For example, in general, in real baseball, it is known that right-hand side arms or under-throw pitchers are well played by left-handed hitter. Therefore, when the user hits with his left hand, he can choose right hand side arm or under-throw pitch. In addition, since a pitcher that is too large compared to his / her height may be hard to hit due to a large falling width in the vertical direction during pitching, the user should consider the degree of his / her height, Can be selected.

As described above, in the present embodiment, various types of pitchers are presented according to whether the virtual pitchers are left-handed or right-handed, how to stretch or what pitching type is, and the like, Regardless of baseball theory, you can choose the pitcher you want, whatever you like to your taste. Here, the type of the pitcher shown in Fig. 7 is merely an example, and the present invention can be applied to other types not shown in the drawings. In any case, the user can select the type of pitcher through the above-described input unit (see reference numeral 121 in FIG. 3) or the like.

8, a virtual pitcher selected by the user is pitched on the screen, and the operation of the hypothetical pitcher on the screen is synchronized with the operation of the pitching machine. In the pitching machine, The ball is configured to be pitched. As a result, the user can get the impression that the ball is actually being pitched in the hands of a hypothetical pitcher being displayed on the screen.

According to the present embodiment, as shown in Fig. 8, the position of the exit of the pitching machine can be adjusted by the position adjuster so that the exit from which the ball is fired in the pitching machine corresponds to the position where the ball is released by the imaginary pitcher have. This is a technical feature of the present invention which is distinguished from the prior art. The reason why such a technical feature can not be implemented in the prior art is as follows.

In the present invention, one of a plurality of types of virtual pitchers is determined by the user's choice, and depending on which pitcher is selected, the release point (the position of the hand at the moment the baseball ball leaves the pitcher's hands) It is different. 7 (a) and (b), for example, there are six different types of pitchers depending on whether the player is left-handed or right-handed and who are classified according to the elongation of the pitcher. (190cm or more), overthrowing pitcher, bigger key (190cm or more) in the right side, pitcher in the third quarter, ..., small key (170cm or less) in the left side, There are a total of 24 different (6 × 4) different pitchers, such as "Under and Under". If they are all different release points, the exit of the pitching machine should be able to be positioned at 24 different positions so that the baseball ball fires corresponding to their release point position.

However, in the prior art, since the position adjuster as in the present invention is not provided, the position of the exit of the pitching machine can not be changed. Further, even if a position controller is added to the prior art to change the position of the exit of the pitching machine, a pitching hole must be formed in the screen to allow the baseball ball emitted from the pitching machine to pass through the screen. , The pitching hole occupies most of the screen, resulting in too many images to be omitted from the screen. Therefore, it is practically impossible to cause the baseball ball to be fired in correspondence with the release point positions of the respective pitchers for various types of pitchers in the prior art, which is a technical feature of the present invention which is different from the prior art.

FIG. 9 is a diagram showing a schematic structure of a screen baseball system using a transmissive screen according to another embodiment of the present invention, FIG. 10 is a view showing an image displayed on a screen in the screen baseball system of FIG. 9, FIG. 12 is a view showing a virtual strike zone divided into a plurality of areas in the screen baseball system of FIG. 9, FIG. 12 is a view showing a case where a virtual batter among the images displayed on the screen in the screen baseball system of FIG. And FIG.

Referring to FIG. 9, the screen baseball system 200 includes a control unit 220, a video output unit 230, and a screen 240. The embodiment described above with reference to FIGS. 1 to 8 relates to a screen baseball system in which a user operates in a 'batting mode' in which a virtual pitcher strikes a ball. In this embodiment, To " pitching mode " Therefore, the screen baseball system 200 according to the present embodiment is also provided with a pitching plate 201 in which a user is positioned to pitch, instead of the striking plate in the previous embodiment.

The control unit 220, the video output unit 230, the screen 240, and the like are substantially the same as those of the previous embodiment, although there are some differences in configuration such as the pitching plate 201. However, there is a difference in operation from the previous embodiment due to operation of the 'pitching mode' instead of the 'batting mode.' For example, in the previous embodiment, the control unit receives the state of the hit ball and calculates the batting result. In this embodiment, the controller 220 receives the state of the ball that the user has pitched, and calculates the pitching result. The difference between the previous embodiment and the present embodiment is a part which can be easily understood by replacing 'betting' with 'pitching'.

Referring to FIG. 10, an image in which a virtual batter is struck is displayed on the screen. Specifically, a hypothetical batter is located at the plate and a virtual catcher is located at the back. In addition, the current ball count is displayed at the back of the virtual catcher, and the strike zone SZ is displayed around the catcher. The strike zone SZ is an area displayed to discriminate whether the ball thrown by the user is a strike or a ball. How to set the strike zone SZ may vary depending on the system, and various methods can be applied.

To describe one example, as shown in FIG. 11, the entire strike zone SZ can be divided into nine regions. The nine regions are composed of a first region SZ1, a second region SZ2, and a third region SZ3. The first region SZ1 is located at the corner of the entire striation zone SZ and the third region SZ3 is located at the center of the entire striation zone SZ. Are located in the remaining portions except for the first and third regions SZ1 and SZ3. Since the first area SZ1 is the edge of the strike zone SZ, it generally corresponds to an area where the batter is hard to strike. Accordingly, when the ball pitched by the user enters the first area SZ1, it is determined that the virtual batter can not hit the strike. Since the third area SZ3 is located in the middle of the strike zone SZ, it corresponds generally to an area where the batter is likely to strike. Accordingly, when the ball pitched by the user enters the third region SZ3, it is determined that the virtual batter hits the ball in an unconditionally hit manner. The second region SZ2 can be regarded as having a batting degree of difficulty corresponding to the middle of the first and third regions SZ1 and SZ3. Therefore, when the ball pitched by the user enters the second region SZ2, The batter is determined to be hit or unable to hit. In applying the probability, the user may detect the speed of the ball thrown and may lower or increase the probability of hitting the ball according to whether the ball is high or low. Or a ball coming into the third region SZ3 may be a double ball, a triple ball, or a homer ball, and a ball coming into the second region SZ2 may be a ball.

As in the previous embodiment, it is preferable that a screen used in this embodiment is a 'transmissive screen' in which a ball pitched by a user can pass through the screen as it is. When a 'transmissive screen' is used, a user may feel as if the pitcher is sucked into the screen and hit the screen after being hit by the screen, which will be described with reference to FIG.

Referring to FIG. 12 (a), when the user's pitch is determined to be a strike in which the virtual batter can not strike, a screen in which a virtual catcher catches the ball is displayed on the screen. According to the present embodiment, a virtual ball is displayed on the screen at the moment the user reaches the screen and collides with the screen or immediately after the collision. In other words, the actual ball that reaches the screen disappears to the back of the screen because the screen is a "transmissive screen", and as soon as the actual ball disappears, a virtual ball caught in the virtual catcher's glove is displayed on the screen, , He feels like he is being sucked into the screen and displayed after his pitching ball hit the screen. As a result, there is an effect that the interest in the screen baseball game can be further improved.

According to the related art, a ball that the user has pitched on the screen collides with the screen and then bounces off to the floor. In addition to the actual pitched ball, a virtual ball is displayed on the screen. Therefore, since the user can simultaneously see two types of actual pitched balls and virtual balls, it is impossible to obtain the effect that the actual pitched balls are sucked into the screen for display.

Referring to FIG. 12 (b), even if a ball that the user has pitched is determined to be hit by a virtual batter, the ball that the user has reached reaches the screen and disappears to the back of the screen, On the screen disappearing to the back of the screen, a scene in which a hypothetical batter bets a virtual ball is displayed on the screen, so that the user feels as if the pitcher himself / herself has hit the screen and is sucked into the screen for display do.

FIG. 13 is a diagram showing a schematic structure of a screen baseball system using a transmissive screen according to another embodiment of the present invention, and FIG. 14 is a view schematically showing an operating state of a ball betting unit in the screen baseball system of FIG. 13 .

Referring to FIG. 13, the screen baseball system 200 includes a ball betting unit 210, a control unit 220, a video output unit 230, and a screen 240. The present embodiment operates in a betting mode, and is not different from the embodiment described with reference to FIGS. 9 to 12, except that it further includes a ball betting unit 210. Therefore, the detailed description of the overlapped portions is omitted except for the differences.

The ball batting portion 210 may be substantially the same as the ball pitching portion 110 in the first embodiment described with reference to Figs. In addition, any structure capable of firing a baseball can be used. The ball betting unit 210 is used for giving a strong sense of realism to the hit when a virtual batter displayed on the screen is determined to be hit with respect to the ball that the user has pitched. That is, as shown in FIG. 14, when a virtual batter hits and hits at the moment when the ball that the user has reached reaches the screen, the ball that the user has pitched to disappears toward the back of the screen, The ball launched from the batting part 210 (only the exit part where the ball is fired in the ball betting part is shown in dotted lines in FIG. 14 for convenience) comes out from the rear side of the screen and flows into the space where the user is positioned do. In this way, when a real baseball ball flies from the rear of the screen, a strong sense of reality can be felt from the user's point of view that a virtual batter displayed on the screen strikes the ball. In order to further increase the sense of realism, the baseball ball may be fired in the vicinity of a point where the ball hit by the user is hit by adjusting the position of the exit of the ball batting unit 210 from which the ball is fired.

The screen according to the embodiment of the present invention uses a transmissive screen as described in the other embodiments described above. Since the transmissive screen is used, even if the exit of the ball betting unit 210 is disposed at an arbitrary position on the screen, the baseball ball launched from the ball betting unit 210 can fly through the screen to the space where the user is located.

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. Therefore, 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.
