Description

  The present invention relates to a virtual sports simulation apparatus capable of performing ball game hitting practice, ball catching practice, and the like using stereoscopic images.

  Patent Literature 1 describes a virtual batting system using a stereoscopic video. This system is for practicing a batting using an image, in which a pitcher's pitch image is displayed three-dimensionally on the screen in front of the player, and the time TC at which the ball passes through the center of the home base is determined from the image on the screen. The determination is automatically made, and the determination of the batting is made based on whether or not the time TP and the time TC when the bat of the player has passed the home base match. This system does not require a large site such as a batting center, and is safe because it does not use actual balls.

JP 2008-93179 A

  However, in Patent Literature 1, since there is only one screen for displaying an image in front of the player, the ball cannot be displayed three-dimensionally near the player (for example, at a position where a hit can be made). For example, a state in which the ball passes through the home base or a state in which the ball deviates to the outer corner of the home base cannot be stereoscopically displayed. Since the player cannot visually recognize the positional relationship between the ball and the bat on the image at a position where the ball can be hit, the position of the ball and the bat on the image (for example, the position in the height direction or the inside angle / outside angle direction) It was not possible to do full-fledged batting practice to match the position).

The virtual sports simulation apparatus according to any one of claims 2 to 7, wherein the right turn at bat image is displayed at a predetermined portion separated from the wall surface display unit by a predetermined distance.

  According to the invention of the first aspect, since two display units are located in at least two directions when viewed from the player, it is possible to stereoscopically display an image of the object near the player. In particular, if one of the at least two display units is a floor display unit, and if the player can stand on the floor display unit, the object will pass until the player passes under the line of sight of the player. Can be stereoscopically displayed. In addition, if the at least two display units are wall display units in two directions when viewed from the player (for example, a wall display unit in the front right direction and a wall display unit in the left front direction), the line of sight of the player or higher than the line of sight is displayed. It is possible to stereoscopically display the image of the object up to the point where the object passes in front of the player on the course.

For example, it is possible to determine that the position of the object and the position of the virtual operating object match when the position of the operating object matches the stereoscopic image of the object in the real space.

  The “virtual space” can be a space on data having a three-dimensional spread. The “object” can be shape data representing the shape of an object (for example, a ball), and the “virtual operating tool” can be shape data representing the shape of the operating tool. The “predetermined part of the player” may be, for example, stereoscopic glasses. If the “object” is a virtual ball (ball shape data), the “operating body” is a bat or mitt, and the “virtual operating body” is a virtual bat or mitt (bat or mitt shape data), the player It is possible to perform full-fledged hitting practice and ball catching practice, such as swinging the bat so that the three-dimensional image of the ball matches the position of the bat or mitt, or moving the mitt. The collision determination can be performed on the positional relationship between the object and the virtual operation body in the space (for example, whether or not the position is correct). The “collision determination” may be a determination as to whether or not the object and the virtual operating object have collided in the virtual space, or may be a determination as to the movement mode (moving speed, moving distance, moving direction, etc.) of the object after the collision. .

[First Embodiment]
FIG. 1 shows a schematic diagram of a virtual baseball device 1 according to one embodiment of the present invention. FIG. 2 shows the arrangement of the three-screen display unit 10 and the projection device 20 (projectors 21L, 21R, 22L, 22R, 23L, 23R) in the upward (FIG. 2A), front (FIG. 2B), and side ( This is shown from FIG.

  As illustrated, the virtual baseball device 1 includes a three-screen display unit 10, a projection device 20, an operation terminal 30, a position detection device 40, and a control device 50. Although not shown, a place for placing the stereoscopic glasses 41 and the dedicated bat 42 is provided near the operation terminal 30. The player P uses the virtual baseball device 1 while wearing the stereoscopic glasses 41 and holding the dedicated bat 42.

  The three-surface display unit 10 includes a floor surface display unit 11, a wall surface display unit (a first wall surface display unit 12 and a second wall surface display unit 13), and first to third bending units 14 to 16.

  The floor surface display unit 11 has a substantially square or square shape, and the first wall surface display unit 12 and the second wall surface display unit 13 have a trapezoidal shape in which the upper side is longer than the lower side. Each of the floor surface display unit 11, the first wall surface display unit 12, and the second wall surface display unit 13 can be a substantially flat surface.

  In the illustrated example, the angle α formed by the first wall surface display unit 12 and the second wall surface display unit 13 is about 90 degrees.

  The angle β formed by the floor display 11 and the first wall display 12 and the angle γ formed by the floor 11 and the second wall 13 are preferably obtuse. In the illustrated example, the angles β and γ are approximately 94 degrees.

  The floor surface display unit 11, the first wall surface display unit 12, and the second wall surface display unit 13 are connected to each other through first to third bending units 14, 15, and 16. Specifically, the floor display unit 11 and the first wall display unit 12 are smoothly connected via a first bending unit 14 having a predetermined radius of curvature, and the floor display unit 11 and the second wall display unit 13 are connected to each other. The first wall surface display unit 12 and the second wall surface display unit 13 are smoothly connected via a second curved portion 15 having a predetermined radius of curvature, and are smoothly connected via a second curved portion 15 having a predetermined radius of curvature. Have been.

  The player P can stand at any position on the floor display unit 11. In the present embodiment, the space (real space) on the floor display unit 11 is referred to as “player space”. In the present embodiment, the position and the direction in the player space are defined as the origin PO at a position near a corner of the floor display unit 11 (a corner facing the first wall display unit 12 and the second wall display unit 13). Description will be made using orthogonal coordinates (XpYpZp coordinates).

  When viewed from the viewpoint of the player P on the floor display unit 11, the floor display unit 11 is located downward (-Zp direction), and the wall display units (the first wall display unit 12 and the second wall display unit 13). Is located forward. More specifically, the first wall surface display unit 12 is located on the front right side (+ Xp direction) of the player P, and the second wall surface display unit 13 is located on the front left side (+ Yp direction) of the player P.

  An area of a certain size near the origin PO in the floor display section 11 is a swing area SR. The swing area SR is an area that is separated from both the first wall surface display unit 12 and the second wall surface display unit 13 by a predetermined distance. In the swing area SR, the player P can safely swing without worrying that the dedicated bat 42 hits the first wall surface display unit 12 and the second wall surface display unit 13.

  The projection device 20 is a device for projecting a three-dimensional image on the three-screen display unit 10. In the present embodiment, a circularly polarized light method is used as a method of displaying a stereoscopic image. Other methods such as a linear polarization method and a frame sequential method may be used as a display method of a stereoscopic image.

  The projection device 20 includes six front projection type projectors 21L, 21R, 22L, 22R, 23L, 23R. The arrangement of the projectors 21L, 21R, 22L, 22R, 23L, 23R is shown in FIG.

  The projectors 21L and 21R are projectors for the floor display unit 11, and are arranged above the first wall display unit 12. The images L1 and R1 from the projectors 21L and 21R are reflected by a mirror 17 disposed near the ceiling above the floor display unit 11, and projected on the floor display unit 11, the first bending unit 14, and the second bending unit 15. You. Since the image is reflected by the mirror 17, the images L1 and R1 are placed on the floor in the same optical path as when the projectors 21L and 21R are arranged at the positions indicated by 21L 'and 21R' in FIGS. 2B and 2C. The image is projected on the surface display unit 11 and the like. When the projectors 21L and 21R are arranged at the positions indicated by 21L 'and 21R' in FIGS. 2B and 2C without using the mirror 17, the projectors 21L and 21R are arranged at lower positions. Therefore, there is an advantage that the height of the virtual baseball device 1 can be reduced. However, if there is no restriction on the height, it is more preferable to install the projectors 21L and 21R at the positions indicated by 21L 'and 21R' because the attenuation of light can be reduced.

  The projectors 22L and 22R are projectors for the first wall surface display unit 12, and are arranged near the ceiling at a position sufficiently distant from the first wall surface display unit 12 in the X direction. The images L2 and R2 from the projectors 22L and 22R are projected obliquely downward on the first wall surface display unit 12 and the first bending unit 14. Therefore, the images L2 and R2 are not easily blocked by the player P. Since the angle β formed by the floor display unit 11 and the first wall display unit 12 is an obtuse angle, the images L2 and R2 are hardly reflected on the first wall display unit 12 and projected on the floor display unit 11, so that Double copying of the images L1 and R1 and the images L2 and R2 is reduced.

  The projectors 23L and 23R are projectors for the second wall surface display unit 13, and are arranged near the ceiling at a position sufficiently distant from the second wall surface display unit 13 in the Y direction. The images L3 and R3 from the projectors 23L and 23R are projected obliquely downward on the second wall surface display unit 13 and the second bending unit 15. Therefore, the images L3 and R3 are not easily blocked by the player P. Since the angle γ formed by the floor surface display unit 11 and the second wall surface display unit 13 is an obtuse angle, the images L3 and R3 are hardly reflected on the second wall surface display unit 13 and projected on the floor surface display unit 11, so that Double copying of the images L1 and R1 and the images L2 and R2 is reduced.

  The images L1, L2, L3 projected by the left projectors 21L, 22L, 23L are circularly polarized images in a specific rotation direction, and the images R1, R2, R3 projected by the right projectors 21R, 22R, 23R are: It is an image of circularly polarized light in the reverse rotation direction.

  By viewing the images L1, L2, L3, R1, R2, and R3 projected on the three-screen display unit 10 through the stereoscopic glasses 41 in which the left and right lenses each have a filter that allows only one circularly polarized light to pass, the floor is displayed. The player P on the surface display unit 11 can recognize the video as a three-dimensional image.

  The operation terminal 30 is an interface for the player P to perform an operation. The operation terminal 30 includes, for example, an input device such as a button or a touch panel, a display device such as a liquid crystal monitor, a speaker that outputs sound, and the like. The operation terminal 30 may include a fee collection device for collecting a usage fee for the virtual baseball device 1 from the player P.

  The position detection device 40 is a device or a system for detecting the position of the stereoscopic glasses 41 in the player space and the position and orientation of the dedicated bat 42 in real time. The detection can be performed using a known capture technique such as an optical type or a magnetic type. In the present embodiment, a plurality of infrared markers (not shown) are attached to the stereoscopic glasses 41 and the dedicated bat 42 in a unique arrangement respectively, and a plurality of infrared markers (for example, front, rear, left, right, up and down) are arranged around the player space. The above detection is performed by analyzing an image taken by an infrared camera (not shown).

  The control device 50 includes one or more computers having a CPU and a storage device. The control device 50 is connected to the projection device 20, the operation terminal 30, and the position detection device 40 by wire or wirelessly, and can mutually transmit and receive data. The control device 50 implements the functional configuration shown in FIG. 3 by executing a program stored in the storage device.

  As illustrated in FIG. 3, the functional configuration of the virtual baseball device 1 includes a virtual model setting unit 61, a turn at bat selection unit (display direction selection unit) 62, a viewpoint position calculation unit 63, a gaze direction setting unit 64, and a stereoscopic video generation unit 65. , A bat position calculation unit 66, a hit result determination unit (collision determination unit) 67, a virtual operation reception unit 68, an analysis result display unit 69, and a player data storage unit 70.

  The virtual model setting unit 61 arranges various objects in a three-dimensional virtual space and operates the objects to generate a virtual model VM (see FIG. 6) that reproduces a situation in which a pitcher pitches in a real stadium. This is set in the virtual space. The virtual model setting section 61 has an object storage section 61a and an operation storage section 61b.

  The object storage unit 61a stores shape data of various objects. The shape data is data representing a three-dimensional shape of the object in a local coordinate system. The shape data can be created, for example, by combining a plurality of polygons. The shape data may include texture data (pattern and color data) for mapping on the surface of the object.

  The objects in the object storage unit 61a include objects corresponding to various things (people, objects, facilities, and the like) existing in the actual stadium. These objects include a movable object that can be moved or moved (for example, a pitcher object V1, a ball object V2, a bat object V3, etc.) and a stationary object that is not moved or moved (for example, a pitching board object V4, left and right bats). Objects V5L, V5R, home base object V5H, outfield fence object V6, etc.). Hereinafter, the left and right at-bat objects V5L and V5R and the home base object V5H may be collectively referred to as a "at-bat object V5". The objects in the object storage unit 61a further include objects (for example, the operation instruction object V7 and the result display object V8 shown in FIG. 13) that do not correspond to the objects existing in the actual ballpark.

  Among the above, the shape data of the object corresponding to the thing existing in the real ballpark is created in the same shape and size as the thing in the real ballpark. For example, the size of the at-bat objects V5L and V5R is 121.92 cm × 182.88 cm, and the pitch of the pitching plate object V4 is 60.96 cm.

  For the pitcher object V1, shape data representing the height, physique, uniform shape, etc. of a real pitcher (for example, a professional baseball pitcher) in full size is used. Each pitcher object V1 is composed of a plurality of parts such as a head, a hand, a foot, and a body, and changes the attitude of the pitcher object V1 by changing the position and orientation of each part with respect to a reference point in a local coordinate system. Is possible. Hereinafter, the shape data of the pitcher object V1 is referred to as “pitcher shape data”.

  As the ball object V2, different shape data is used according to the moving speed of the ball object V2. FIG. 4 shows the shape of the ball object V2.

  FIG. 4A shows a case where the ball object V2 is stationary, and has only a spherical main body V2a. The diameter of the main body portion V2a is about 7 cm, like a real baseball ball.

  FIGS. 4B and 4C show the shapes of the ball object V2 when moving at a low speed (for example, 100 km / h) and a high speed (for example, 150 km / h). 4B and 4C, the spherical main body V2a is divided into a front hemispherical portion V2a1 and a rear hemispherical portion V2a2, between which a cylindrical shape having the same diameter as the diameter of the main body V2a is provided. This is a shape to which an extension V2b (motion blur) is added. Also, as the ball object V2 is faster, a longer extension V2b is added, and the length D1 of the ball object V2 is longer. For example, the length D1 can be calculated by D1 = A × D2, where D2 is the distance that the ball object V2 moves during one frame time (for example, 1/120 second). The constant A can be, for example, 0.6 to 0.8, preferably 0.65 to 0.75. In the following description, the hemispherical portion V2a1 and the hemispherical portion V2a2 are collectively referred to simply as “main body portion V2a”.

  The rotation of the ball can be expressed by mapping the texture V2c of the pattern representing the seam on the main body V2a and changing the position of the texture V2c on the main body V2a in accordance with the movement of the ball object V2. The texture V2c may be mapped only to the hemisphere portion on the front side of the main body V2a.

  As a modification, the size of the ball object V2 (the diameter and the length D1 of the main body portion V2a and the extension portion V2b) may be further increased according to (for example, in proportion to) the moving speed of the ball object V2.

  The motion storage unit 61b stores the motion data of the movable object. In the present embodiment, pitching motion data for moving the pitcher object V1 and ball motion data for moving the ball object V2 are stored as motion data.

  The pitcher motion data defines the attitude of the pitcher object V1 in a time series every predetermined time (for example, 1/120 second) from the start of the pitching motion of the pitcher object. The pitcher motion data is created by converting the actual pitching motion of the pitcher into data. By operating the pitcher object V1 in accordance with the pitcher motion data, the pitcher object V1 is formed in the same form as the actual pitcher. Perform a pitching action.

  The ball motion data defines the position coordinates of the ball object V2 in the virtual space every predetermined time (for example, 1/120 second) from the start of the movement of the ball object. The ball motion data is created by converting the pitch of the actual pitcher (moving path and speed of the ball) into data. By moving the ball object V2 in accordance with the ball motion data, the ball object V2 becomes the actual pitcher. Moves in the virtual space with the same moving path and speed as the ball that has been thrown.

  In the present embodiment, a plurality of pairs of pitcher shape data, pitcher motion data, and ball motion data are created corresponding to a plurality of real pitchers. FIG. 5 shows the correspondence between the actual pitcher and each data.

  In FIG. 5, pitchers A, B, C,... Are real pitchers. The real pitcher may be, for example, a real professional baseball pitcher. Each pitcher shape data is created in one-to-one correspondence with a real pitcher. Real pitchers have various types of pitches, such as straights, curves, and shoots, and pitching forms may differ depending on the type of pitch. However, if pitcher motion data is created for each pitch, the amount of data becomes enormous. For this reason, in the present embodiment, two types of data of the pitcher motion data are created for each pitcher: a straight type and a changing ball type. Straight pitcher movement data is created based on the pitch form when a real pitcher pitches a straight pitch, and changing pitcher movement data is based on the actual pitcher's pitching pitch. It is created based on the pitch form at the time of pitching. The ball motion data is created by converting the pitches of the actual pitcher's balls for each pitch type into data.

  The virtual model setting unit 61 sets a virtual model VM by arranging various objects in the object storage unit 61a in a virtual space. The virtual space is a space on data having a three-dimensional spread. As the coordinate system of the virtual space, a coordinate system (world coordinate system) different from the local coordinate system is used. In the present embodiment, the position and direction in the virtual space will be described using orthogonal coordinates (XvYvZv coordinates) having the point VO in the virtual space as the origin.

  FIG. 6 illustrates an exemplary virtual model VM set in the virtual space. In the virtual model VM, stationary objects such as the pitching plate object V4, the left and right at-bat objects V5L and V5R, the home base object V5H, and the outfield fence object V6 have the same positional relationship and the same distance as the actual ballpark, based on the origin VO. Are located. The orientation and positional relationship of the pitching board object V4, the left and right at-bat objects V5L and V5R, the home base object V5H, and the like are arranged in the same orientation and positional relationship as the actual ballpark. For example, the home base object V5H is located between the left and right at-bat objects V5L and V5R. Also, the home base object V5H (bat object V5) is arranged in the direction of the throwing plate object V4. The distance from the home base object V5H to the pitching board object V4 is 18.44 m. In the virtual model VM, other objects such as a first base, a second base, a third base, a first base line, a third base line, a fielder, a spectator seat, a spectator, and a signboard may be arranged with the same positional relationship and the same distance as that of the real stadium. . Thereby, a real stadium can be reproduced more realistically.

  The virtual model setting unit 61 further arranges the pitcher object V1 near the pitcher board object V4, causes the pitcher object V1 to perform a pitching motion according to the pitcher motion data, and moves the ball object V2 according to the ball motion data. The pitching motion of the pitcher object V1 and the movement of the ball object V2 are synchronized, and the ball object V2 starts to move at the timing when the pitcher object V1 shakes his hand.

  FIG. 7 is a diagram of the virtual model VM as viewed from the Zv direction, and shows the arrangement of the pitcher object V1 and the movement path of the ball object V2.

  In FIG. 7, X1 and X2 indicate positions on the Xv coordinate of the start point and the end point of the movement path of the ball object V2. The start point position (X1) is a position on the home base object V5H side by a predetermined distance from the throwing plate object V4 in the X direction, and the end point position (X2) is a position behind the home base object V5H by a predetermined distance.

  Since the ball movement data is created based on the actual pitcher's pitch, the movement path between X1 and X2 of the ball object V2 is c1 to c3 depending on the type and course of the same pitcher. As illustrated, the position in the Yv direction of the ball object V2 at the starting point of the movement path changes in a range like Y1-Y2 in the figure depending on the type of the ball and the course.

  In the present embodiment, the position of the pitcher object V1 in the Yv direction is adjusted according to the position in the Yv direction of the starting point of the moving route. Specifically, the position of the pitcher object V1 is adjusted such that the position in the Yv direction of the hand of the pitcher object V1 performing the pitching operation matches the position in the Yv direction of the starting point of the movement path. Thus, even when the position of the starting point on the Y-axis changes depending on the type of the ball or the course, it is possible to visualize how the ball is naturally released from the pitcher's hand using the same pitcher motion data. Therefore, the types of pitching motion data can be reduced, and the labor required for data creation can be reduced.

  Note that the position of the start point of the ball object V2 changes not only in the Yv direction but also in the Zv direction depending on the movement path. However, in the present embodiment, the position adjustment of the pitcher object V1 in the Zv direction is not performed. When an image is actually created, even if the position of the ball object V2 of the hand of the pitcher object V1 is slightly shifted in the Zv direction, it appears that the ball is naturally released from the hand of the pitcher, and This is because it has been found that when the pitcher object V1 is moved in the Zv direction, the sense of discomfort when viewing the video is large.

  The range of movement of the ball object V2 in the Xv direction (range of X1-X2) and the range of movement of the ball object V2 in the Yv direction (Y1-Y2) shown in FIG. 7 are examples, and these can be different from those in FIG. .

  The turn at bat selection unit 62 selects one of a left at bat and a right at bat in response to an operation of the player P on the operation terminal 30.

  The viewpoint position calculation unit 63 calculates positions in the virtual space corresponding to the positions of the stereoscopic glasses 41 in the player space detected by the position detection device 40 as left and right virtual viewpoint positions L and R. The calculation is performed by a different method depending on whether the turn at bat selected by the turn at bat selection section 62 is a left at bat or a right at bat. The left and right virtual viewpoint positions L and R are arranged at positions separated by DP in the Yv direction. The distance DP corresponds to the distance between the eyes of a person (the distance between the left and right eyes). The distance DP can be, for example, 6.5 cm, which is the average binocular distance of Japanese.

  FIG. 8 conceptually shows a state where a three-dimensional image is displayed on the three-screen display unit 10 when the turn at bat selected by the turn at bat selection unit 62 is a left at bat. In practice, the batter stands in the left at bat, and this position is set near the center of the room so that it is safe when the batter swings the bat. In terms of coordinates, the pitcher image E1 is displayed on the first wall portion 12 located in the Xp direction, and the ball image E2 moves toward the home base image E5H along the Xp coordinates.

  FIG. 9 conceptually shows a state where a three-dimensional image is displayed on the three-screen display unit 10 when the turn at bat selected by the turn at bat selection unit 62 is a right at bat. Actually, as shown in FIG. 8, when the batter stands at the right at bat and swings the bat, it is set near the center of the room so as to be safe, and the home base image E5H displayed on the floor display unit 11 is the same as FIG. The angle is changed by 90 degrees in plan view. When represented by coordinates, the pitcher image E1 is displayed on the second wall surface display unit 13, and the pitch image moves to the home base along the Yp coordinates.

  Therefore, if the stereoscopic glasses 41 move in the XpYp plane of the player space as the player P walks in the floor display unit 11, the left and right virtual viewpoint positions L and R are set to the corresponding positions in the XvYv plane in the virtual space. Moving. When the stereoscopic glasses 41 move in the Zp direction due to the player P standing or squatting, the left and right virtual viewpoint positions L and R move to the corresponding positions in the Zv direction in the virtual space.

  Note that the method of calculating the left and right virtual viewpoint positions L and R is not limited to the above. For example, in the case of a left turn at bat, a position in the virtual space having the same coordinates as the stereoscopic glasses 41 is calculated, and positions obtained by shifting the Yv coordinate by ± DP / 2 from the position are calculated as left and right virtual viewpoint positions L and R. However, in the case of right turn at bat, a position in the virtual space at the same coordinate as the position where the Xp coordinate and the Yp coordinate of the position of the stereoscopic glasses 41 are exchanged is calculated, and the Yv coordinate is shifted from the position by ± DP / 2. The left and right virtual viewpoint positions L and R may be calculated.

  The line-of-sight direction setting unit 64 sets three line-of-sight directions according to whether the turn at bat selected by the turn at bat selection unit 62 is a left at bat or a right at bat. In FIG. 6, three line-of-sight directions for left at bat are shown by arrows LA1, LA2, and LA3 extending from the left and right virtual viewpoint positions L and R, and three line of sight directions for right at bat are shown from the left and right virtual viewpoint positions L and R. It is shown by extending arrows RA1, RA2, RA3. As shown in the figure, the line-of-sight directions LA1, LA2, and LA3 for left at-bat are respectively -Zv, + Xv, and + Yv directions, and the line-of-sight directions RA1, RA2, and RA3 for right at-bat are -Zv, + Xv, and + Xv, respectively. -Yv direction.

  The stereoscopic video generation unit 65 uses the left and right virtual viewpoint positions L and R calculated by the viewpoint position calculation unit 63 to generate a virtual model in three line-of-sight directions LA1, LA2, LA3 or RA1, RA2, and RA3 set by the line-of-sight direction setting unit 64. By rendering the video as viewed from the VM, six videos L1, L2, L3, R1, R2, and R3 are generated.

  Specifically, when the turn at bat selected by the turn at bat selection unit 62 is a left at bat, the images L1, L2, and L3 are generated as images when the direction of LA1, LA2, and LA3 is viewed from the left virtual viewpoint position L, respectively. Then, the images R1, R2, and R3 are generated as images when the direction of LA1, LA2, and LA3 is viewed from the right virtual viewpoint position R. When the turn at bat selected by the turn at bat selection section 62 is a right at bat, the images L1, L2, and L3 are respectively generated as images when the direction of RA1, RA2, and RA3 is viewed from the left virtual viewpoint position L, and the images R1, R2 and R3 are generated as images when viewing the directions of RA1, RA2 and RA3 from the right virtual viewpoint position R.

  The images L1, L2, L3, R1, R2, and R3 are generated at predetermined frame times (for example, 1/120 seconds), and the images L1, L2, L3, R1, R2, and R3 at each frame time are generated. Is projected on the three-screen display unit 10 by the projection device 20. Specifically, the images L1 and R1 are projected by the projectors 21L and 21R, the images L2 and R2 are projected by the projectors 22L and 22R, and the images L3 and R3 are projected by the projectors 23L and 23R.

  8 and 9 show that the player P on the floor display unit 11 views the images L1, L2, L3, R1, R2, and R3 projected on the three-screen display unit 10 through the stereoscopic glasses 41 as described above. FIG. 4 conceptually shows a state in which a player P recognizes images L1, L2, L3, R1, R2, and R3 as stereoscopic images.

  FIG. 8 shows a case where the turn at bat selected by the turn at bat selection section 62 is a left at bat. As shown in the figure, the images corresponding to the pitcher object V1 and the pitcher board object V4 are stereoscopically displayed on the first wall surface display section 12 as the pitcher video E1 and the pitcher board video E4, and the left and right at-bat objects V5L, V5R and the home base object V5H are displayed. The corresponding images are stereoscopically displayed on the floor display unit 11 as left and right turn at bat images E5L and E5R and a home base image E5H. Hereinafter, the left and right turn at bat images E5L and E5R and the home base image E5H may be collectively referred to as “bat at bat image E5”. An image corresponding to the outfield fence object V6 is displayed as an outfield fence image E6 from the first wall surface display unit 12 to the second wall surface display unit 13. The home base image E5H (at-bat image E5) is displayed in a state facing the direction of the first wall surface display unit 12 (the pitcher image E1). The left turn at bat image E5L is displayed in the swing area SR.

  An image corresponding to the ball object V2 is stereoscopically displayed as a ball image E2. Corresponding to the ball object V2 having a main body V2a and an extension V2b, the ball image E2 has a main body E2a and an extension E2b. The ball image E2 is three-dimensionally moved from the position of the pitcher image E1 through the position where the player P can hit with the dedicated bat 42 to the rear of the home base image E5H according to the movement of the ball object V2 in the virtual space. Is displayed. That is, the player P recognizes that the ball object V2 moves in the player space along the movement path corresponding to the movement path of the ball object V2 in the virtual space. Therefore, the player P can swing the dedicated bat 42 in time with the moving ball image E2 and in accordance with the position of the ball image E2 in the XpYpZp direction in the player space. You can practice hitting with the same feeling as hitting with a ball.

  The actual display position of the ball image E2 on the three-side display unit 10 (the display position of the ball image E2 in the images L1, L2, and L3 when viewed with the naked eye, and the display position of the ball image E2 in the images R1, R2, and R3) The movement path of the display position of the ball image E2 / the same hereinafter) varies depending on the movement path of the ball object V2. For example, if the course of movement of the ball object V2 is a low course, the actual display position of the ball image E2 moves from the first wall display unit 12 to the floor display unit 11 via the first bending unit 14, and then the floor display unit 11 It moves on the surface display unit 11 in the −X direction. If the course has a higher outside angle, the course moves from the first wall display section 12 to the second wall display section 13 via the third bending section 16, and then moves on the second wall display section 13 in the -X direction.

  If the floor display section 11, the first wall display section 12, and the second wall display section 13 are directly connected without a curved section, the actual display position of the ball image E2 is one display section ( When moving from the first wall surface display unit 12) to another display unit (the floor surface display unit 11 or the second wall surface display unit 13), the three-dimensional ball image E2 recognized by the player P is an unnatural path (jerky). It looks as if it is moving along a curved path or a bent path).

  In the present embodiment, the floor surface display unit 11, the first wall surface display unit 12, and the second wall surface display unit 13 are smoothly connected via first to third curved portions 14 to 16 having appropriate curvature radii. When the actual display position of the ball image E2 moves from one display unit (for example, the first wall display unit 12) to another display unit (for example, the floor display unit 11 or the second wall display unit 13), Always travels through the first to third curved portions 14 to 16, the above-mentioned inconvenience does not occur, and the player P receives the natural image of the ball image E <b> 2 (the actual pitcher is It appears to be moving on the same path as the actual ball that was thrown).

  FIG. 9 shows a case where the turn at bat selected by the turn at bat selection section 62 is a right at bat. As shown in the drawing, the images corresponding to the pitcher object V1 and the pitcher board object V4 are stereoscopically displayed on the second wall surface display section 13 as the pitcher video E1 and the pitcher board video E4, and are displayed on the left and right at-bat objects V5L, V5R and the home base object V5H. The corresponding images are stereoscopically displayed on the floor display unit 11 as left and right turn at bat images E5L and E5R and a home base image E5H. An image corresponding to the outfield fence object V6 is displayed as an outfield fence image E6 from the first wall surface display unit 12 to the second wall surface display unit 13. The home base image E5H (batting image E5) is displayed in a state where it faces the direction of the second wall surface display unit 13 (the pitcher image E1). Therefore, the direction of the home base image E5H (at bat image E5) differs by 90 degrees between the case where the bat selected by the bat selection unit 62 is the left bat and the case where the bat is a right bat. The right turn at bat image E5R is displayed in the swing area SR.

  As in the case of the left at bat, the ball image E2 corresponding to the ball object V2 has a three-dimensional display in which the player P moves from the position of the pitcher image E1 to the rear of the home base image E5H through a position where the player P can hit with the dedicated bat 42. Is done. Therefore, the player P can swing the dedicated bat 42 in synchronization with the timing of the ball image E2 displayed in three dimensions and the position of the ball image E2 in the XpYpZp direction in the player space. You can practice hitting with the same feeling as hitting with a ball.

  Since the floor display unit 11, the first wall display unit 12, and the second wall display unit 13 are connected via the first to third bending units 14 to 16, the ball image E2 moves along a natural route. The point that the player P can recognize as described above is also the same as the case of FIG.

  Further, as described above, the direction and position of the at-bat image E5 are switched and displayed depending on whether the at-bat turn selected by the at-bat select unit 62 is a left at-bat or a right at-bat. Is directed to the first wall surface display section 12 and the left turn at bat image E5L is displayed so as to be positioned in the swing area SR. In the case of right turn at bat, the home base image E5H is directed to the second wall surface display section 13 and is directed to the swing area SR. Is displayed so that the right turn at bat image E5R is positioned at the right side), so that the area of the floor display unit 11 can be reduced. The difference between the direction of the home base image E5H when the turn at bat selected by the turn at bat selection section 62 is a left turn at bat and a right turn at bat does not have to be strictly 90 degrees, and may have a certain width. A preferred range of the difference in the direction of the home video E5H is 80 degrees to 100 degrees, and a more preferred range is 85 degrees to 95 degrees.

  In addition, when the at-bat turn selecting unit 62 selects the left at-bat, the left at-bat image E5L is displayed in the swing area SR. Therefore, the player P displays the dedicated bat 42 in the first at-bat image in the left at-bat image E5L. It is possible to swing safely without worrying about hitting the section 12 or the second wall display section 13, and when the turn at bat selection section 62 selects right turn at bat, the right turn at bat image E5R is displayed in the swing area SR. The player P can safely swing without worrying that the dedicated bat 42 will hit the first wall surface display unit 12 or the second wall surface display unit 13 in the right turn at bat image E5R.

  In the present embodiment, as described with reference to FIG. 4, an extension V2b (extension E2b) having a length corresponding to the moving speed of the ball object V2 is added behind the main body V2a (main body E2a). . This makes it easier for the player P to recognize the difference in the speed of the ball image E2. Further, even when the moving speed of the ball object V2 is such a high speed that the ball object V2 moves a distance longer than the diameter of the ball object V2 during one frame time, the ball image E2 continuously moves. This makes it easier for the player P to recognize.

  Further, when the size of the ball object V2 is increased in accordance with the moving speed of the ball object V2, the sense of speed of the ball image E2 when the ball object V2 moves at high speed can be increased (the ball feeling). The player P can recognize that the image E2 is moving at a higher speed.)

  The bat position calculation unit 66 calculates the position and the direction of the bat object V3 in the virtual space in real time based on the position and the direction of the dedicated bat 42 detected by the position detection device 40. When the turn at bat selected by the turn at bat selection section 62 is the left at bat, the position and the orientation of the bat object V3 are calculated to be the same as the position and the orientation of the dedicated bat 42 in the player space. That is, if the position coordinates of the dedicated bat 42 in the player space are (a, b, c), the position coordinates of the bat object V3 in the virtual space are (a, b, c), and the dedicated bat 42 is in the player space. If the direction (for example, the vector from the handle of the dedicated bat 42 toward the tip) is the + Zp direction, the direction of the bat object V3 in the virtual space (for example, the vector from the handle of the bat object V3 to the tip) is the + Zv direction. It becomes. When the turn at bat selected by the turn at bat selection unit 62 is a right at bat, the position and orientation in the virtual space where the Xp coordinates and the Yp coordinates of the position and orientation of the dedicated bat 42 in the player space are exchanged are calculated.

  When the player P swings the dedicated bat 42 with respect to the flying ball image E2, the batting result determination unit 67 determines the position (movement path) of the ball object V2 in the virtual space and the bat calculated by the bat position calculation unit 66. The hitting result is determined based on the position (moving route) of the object V3. Specifically, if the distance between the ball object V2 and the bat object V3 in the virtual space when the ball object V2 comes closest to the bat object V3 is less than a predetermined value (for example, 5 cm), the ball object V2 and the bat object V3 collide. Is determined to be a successful hit. On the other hand, if the distance at the time of the closest approach is equal to or more than a certain value, it is determined that there is no swing. If it is determined that the player P has not swinged from the position and orientation of the bat object V3 calculated by the bat position calculation unit 66, it is determined that the player P has not been swung.

  Furthermore, in the case of a successful hit, the hit result determination unit 67 determines the head speed of the bat object V3 and the direction of the hit ball based on the position and orientation of the bat object V3, the collision timing and the collision angle between the ball object V2 and the bat object V3, and the like. (Right direction, center direction, left direction, etc.) and base hit information (foul, single hit, two base, three base, home run, etc.) are determined.

  The virtual operation accepting unit 68 accepts an operation on the operation instruction image E7 corresponding to the operation instruction object V7 stereoscopically displayed in the player space in a process of an operation acceptance (step S8) described later.

  Specifically, as illustrated in FIG. 10, the virtual model setting unit 61 arranges the operation instruction object V7 at a predetermined height position near the at-bat object V5 in the virtual space. The operation instruction object V7 is composed of a portion V7a displaying the character "repeat" and a portion V7b displaying the character "analysis". By rendering the virtual model VM on which the operation instruction object V7 is arranged by the three-dimensional image generation unit 65, the operation instruction image E7 is placed at a predetermined height near the turn at bat image E5 in the player space, as shown in FIG. 3D display.

  When the turn at bat selected by the turn at bat selection section 62 is a right at bat, the operation instruction object E7 may be displayed near the right at bat image E5R by arranging the operation instruction object V7 near the right at bat object V5R. If the turn at bat selected by the turn at bat selection section 62 is a left at bat, the operation instruction object E7 is displayed near the left at bat image E5L by placing the operation instruction object V7 near the left at bat object V5L. Good.

  The player P can perform an operation with the dedicated bat 42 on the operation instruction image E7 stereoscopically displayed as described above. The virtual operation receiving unit 68 receives an operation of the player P based on the position of the bat object V3 in the virtual space calculated by the bat position calculating unit 66. That is, when the position of the bat object V3 matches the position of the portion V7a, the operation of "repeat" is accepted, and when the position of the bat object V3 matches the position of the portion V7b, the operation of "analysis" is accepted.

  The analysis result display unit 69 displays the determination result by the hit result determination unit 67 on the three-screen display unit 10 in the process of displaying the analysis result (step S9) described later.

  The player data storage unit 70 stores, for each of the plurality of players P, identification information, height, and distinction between right and left at bats (right at bat if the player P is a right batter, left if the player P is a left batter, Bats) have been recorded. The identification information may be the name, ID, uniform number, etc. of the player P.

  FIG. 12 shows a flow of the hitting practice process executed in the virtual baseball device 1.

  In step S <b> 1, the player P inputs his / her identification information to the operation terminal 30, and the turn at bat selection section 62 corresponds to the identification information input by the player P by referring to the data in the player data storage section 70. Select the at-bat (either right at-bat or left at-bat).

  In step S2, a pitcher as an opponent is selected according to the operation of the player P on the operation terminal 30. The pitcher of the opponent can be selected from the pitchers A, B, C,... Shown in FIG.

  In step S3, a pitch and a course are selected. The pitch is selected from the ball movement data corresponding to the pitcher selected in step S2. The method of selecting the pitch and course is arbitrary. The player P may be able to select by operating the operation terminal 30, or may be automatically selected based on the past pitching tendency data of the actual pitcher corresponding to the pitcher selected in step S2. Good.

  In step S4, the stereoscopic video generation unit 65 displays the stereoscopic video of FIG. 8 or FIG. 9 on the three-screen display unit 10 according to the left and right of the turn at bat selected by the turn at bat selection unit 62 in step S1. At this point, the pitcher object V1 is in a state before the start of the pitching operation, and the ball object V2 is not arranged in the virtual space. When the position detection device 40 cannot detect the stereoscopic glasses 41 in the player space, the viewpoint position calculation unit 63 sets an appropriate position in the virtual space (for example, lastly, in the previous hitting practice, the stereoscopic glasses 41 (Left and right virtual viewpoint positions L, R) calculated at the time of detection of the position.

  In step S5, it is determined whether or not the player P has entered a bat based on the position of the stereoscopic glasses 41. More specifically, if the at-bat at bat selected in step S1 is a left at-bat, it is determined that the player has entered at-bat when the stereoscopic glasses 41 are positioned on the left at-bat image E5L, and the at-bat selected at step S1 is at right at-bat. In this case, if the stereoscopic glasses 41 are positioned on the right turn at bat image E5R, it is determined that the player has entered the turn at bat.

  If the determination in step S5 is affirmative (Yes), the process proceeds to step S6, and if negative (No), step S5 is repeated.

  In step S6, a pitching image is displayed. Specifically, the virtual model setting unit 61 causes the pitcher object V1 to perform a pitching operation, and moves the ball object V2 in the virtual space in synchronization with the pitching operation. Thereby, as shown in FIG. 8 or FIG. 9, the ball image E2 moving from the position of the pitcher image E1 to the rear of the home base image E5H through the vicinity of the player P is stereoscopically displayed. The player P swings the dedicated bat 42 so that the position and timing in the XpYpZp direction match the ball image E2.

  In step S7, the impact result determination section 67 determines an impact result.

  In step S8, the virtual operation reception unit 68 waits for an operation on the operation instruction image E7 by the player P for a certain period of time. Specifically, the virtual operation receiving unit 68 stereoscopically displays the operation instruction image E7 in the player space in a manner as shown in FIG. 11, and the player P sends a dedicated bat to the part E7a or E7b of the operation instruction image E7. When the operation is performed at 42, the virtual operation reception unit 68 receives an operation of “repeat” or an operation of “analysis”.

  As described above, since the operation instruction image E7 is displayed near the at-bat image E5, the player P can perform an operation (an operation of "repeat" or an "analysis" operation) while staying at the at-bat. is there. This is convenient because the operation can be performed without moving to a place away from the three-screen display unit 10 (for example, a place of the operation terminal 30).

  When the operation of “analysis” is received in step S8, the process proceeds to step S9, and the analysis result display unit 69 displays the analysis result.

  Specifically, the analysis result display unit 69 causes the virtual model setting unit 61 to execute a process of additionally arranging the ball object V2, the bat object V3, the result display object V8, and the like in the virtual space. FIG. 13 shows an example of the arrangement of each object in step S9.

  As shown in the figure, the ball object V2 and the bat object V3 are respectively arranged at positions where the ball object V2 and the bat object V3 come closest when the player P swings the dedicated bat 42 in step S6. In this example, the case where the ball object V2 having only the main body V2a is arranged is shown as an example. However, similarly to the case of FIG. 6, the ball object V2 having the main body V2a and the extension V2b may be arranged. Good.

  The result display object V8 is arranged near the bat object V3. The result display object V8 has a head speed display unit V8a indicating the head speed of the dedicated bat 42 determined by the hit result determination unit 67, and a direction similar hit display unit V8b indicating the flying direction and similar hit information. The “two hits to the right” in the illustrated direction hit display portion V8b indicates that the hit ball is in the right direction (light direction) and is a double hit.

  By rendering the virtual model VM on which the ball object V2, the bat object V3, the result display object V8 and the like are arranged by the three-dimensional image generation unit 65, as shown in FIG. 14, the ball image E2, the bat image E3, and the result display The image E8 is stereoscopically displayed in the player space. By watching such an image, the player P can easily understand the result of the hit in step S6. For example, looking at the positional relationship between the ball image E2 and the bat image E3, in the case of a successful hit, at what position and at what angle the ball image E2 and the dedicated bat 42 collided, Indicates how far the ball image E2 and the dedicated bat 42 have been separated from each other.

  When the operation of “repeat” is received in step S8, the process proceeds to step S6, and the processes of steps S6 to S8 are executed again. Therefore, the player P can perform the hitting practice with the same pitch and course as many times by performing the operation of “repeat”.

  In step S8, if the operation on the operation instruction image E7 is not detected for a certain period of time, the process proceeds to step S3, and the processing of steps S3 to S8 is executed again. As a result, a new pitch and a new course are selected, and the player P can practice hitting with the new pitch and the new course.

  As described above, the virtual baseball device 1 of the present embodiment has at least three display units (floor display unit 11, first wall display unit 12, and second wall display unit 13) located in three directions. The ball image E2 can be stereoscopically displayed close to the player P (for example, a position where the ball can be hit with the dedicated bat 42). In addition, the player P can practice the batting with the dedicated bat 42 in accordance with the position and timing of the ball image E2, and the batting result is determined based on the positions of the ball object V2 and the bat object V3 in the virtual space. . Therefore, it is possible to perform a hitting practice with the same feeling as a hitting practice with a real ball.

  As shown in FIGS. 8 and 9, a three-dimensional image reproducing the actual stadium is displayed on the three-screen display unit 10 covering almost the entire range of the field of view seen from the player P in the batting posture. Therefore, the player P can feel the same sense of reality as a real stadium.

  Further, since the length L of the ball object V2 increases in accordance with the moving speed of the ball object V2, the sense of speed of the ball image E2 becomes easy to understand (at high speed, the player P recognizes that the ball image E2 is moving at high speed). When the ball object V2 is moving at a low speed, the player can easily recognize the ball image V2 when moving at a low speed. In addition, even when the moving speed of the ball object V2 is high, the ball image E2 is continuously (rather than jumping). It becomes easier for the player P to recognize as if it is moving.

  Further, the position of the pitcher object V1 in the Yv direction is adjusted according to the position in the Yv direction of the starting point of the movement path of the ball object V2. As a result, as shown by c1 to c3 in FIG. 7, even when the moving path of the ball object V2 (the position in the Yv direction at the start of the movement) differs depending on the type of the ball and the course, the pitcher moves using the same pitcher motion data. The image in which the ball image E2 is naturally released from the hand of the image E1 can be obtained.

[Second embodiment]
In the first embodiment, a value of 6.5 cm is used as the distance DP between the left virtual viewpoint position L and the right virtual viewpoint position R in accordance with the average binocular distance of the Japanese. However, if the distance between the eyes of the player P is significantly different from the average value, the positional relationship between the ball image E2 and the dedicated bat 42 in the player space recognized by the player P, and the ball object V2 and the bat in the virtual space. A deviation occurs between the positional relationships of the object V3. Therefore, for example, in the recognition of the player P, there are problems such as that although the position of the ball image E2 and the dedicated bat 42 are surely matched, the batting result determination unit 67 does not determine that the batting has failed. In order to address this problem, the virtual baseball device 1 of the second embodiment has a parallax adjustment function of adjusting the distance DP for each player P. FIG. 15 shows a flowchart of the parallax adjustment processing executed in the virtual baseball device 1 of the second embodiment.

  In step S21, the player P inputs his / her own identification information to the operation terminal 30, and the turn at bat selection section 62 selects either right turn at bat or left turn at bat by referring to data in the player data storage section 70. I do.

  In step S22, the parallax adjustment video is displayed on the three-screen display unit 10. FIG. 16A illustrates a virtual model VM set in the virtual space by the virtual model setting unit 61 to generate a parallax adjustment video. As shown in the figure, the bat objects V5L, V5R and the home base object V5H are arranged in the virtual model VM in the same manner as in FIG. 6, and the ball object V2 stops at a predetermined height above the home base object V5H. It is arranged in a state.

  The position of the ball object V2 is preferably in the middle of the strike zone. That is, as shown in FIG. 16A, the Xv coordinate and the Yv coordinate of the ball object V2 are the middle positions in the Xv direction and the Yv direction of the home base object V5H, respectively. As shown in FIG. 16B, the Zv coordinate value (Z1) of the ball object V2 is in the middle of the strike zone in the height direction (Zv direction). The strike zone can be set based on the height of the player P specified by the identification information input in step S21.

  A mark V2d indicating the center of the ball object V2 is added to the ball object V2.

  FIG. 16C shows a state where the parallax adjustment video is displayed on the three-screen display unit 10 based on the virtual model VM. The figure shows a case where the right turn at bat has been selected in step S21. Corresponding to the position of the ball object V2 in the virtual space, the ball image E2 is displayed at the middle position of the strike zone in the player space as shown in the parallax adjustment image. At the center of the ball image E2, a mark image E2d corresponding to the mark V2d is displayed.

  In step S23, with the player P wearing the stereoscopic glasses 41, the player swings the dedicated bat 42 aiming at the mark image E2d. In step S23, a message E9 of an instruction to the player P, such as "hit the center of the displayed ball."

  In step S24, based on the position of the bat object V3 calculated by the bat position calculation unit 66, the bat object V3 is centered on the home base object V5H in step S23 (the center in the Yp direction when left at bat, and , Xp direction center), the Z-direction coordinate value (Z2) of the bat object V3 is calculated.

  In step S25, the difference (Z1-Z2) between the coordinate value (Z1) in the Z direction of the ball object V2 in step S21 and the coordinate value (Z2) in the Z direction of the bat object V3 calculated in step S24 is calculated.

  In step S26, the distance DP is adjusted based on the difference (Z1-Z2) calculated in step S25. Specifically, when the difference (Z1-Z2) is positive, that is, when the position of the bat object V3 is lower than the position of the ball object V2, the distance DP is reduced, and conversely, the difference DP If (Z1-Z2) is negative, that is, if the position of the bat object V3 is higher than the position of the ball object V2, the distance DP is adjusted to be increased. In step S26, adjustment is performed such that the larger the absolute value of the difference (Z1-Z2), the larger the increase / decrease in the distance DP.

  In the virtual baseball apparatus 1 of the second embodiment, after the parallax adjustment processing is performed, the batting practice processing is executed using the distance DP adjusted in step S26. Thereby, the batting result determination unit 67 can determine the batting result so as to match with the recognition of the player P. Therefore, the player P may perform the parallax adjustment processing before performing the batting practice processing.

  As a modification of the second embodiment, the processing of steps S22 to S26 is repeatedly performed a plurality of times until the difference (Z1−Z2) becomes equal to or less than a certain value (for example, 2 cm). The accuracy of the adjustment of the distance D can be improved. As yet another modified embodiment, the difference (Z1-Z2) is calculated a plurality of times by repeatedly performing the processing of steps S23 to S25 a plurality of times, and then using the average value of the difference (Z1-Z2). The distance D may be adjusted in step S26. Also in this case, the accuracy of adjusting the distance D can be improved.

  The preferred embodiments have been described above, but the devices, programs, means, or their elements, operation modes, control modes, control parameters, and the like in the above embodiments are described as examples, and these may be variously modified. It is possible to do.

  For example, in the above-described embodiment, a case has been described where an image is projected on the three-screen display unit 10 using a projection-type projector, but the image display method is arbitrary. For example, the three-screen display unit 10 may be a three-dimensional television such as a liquid crystal display method or a plasma display method. Further, in the above-described embodiment, the three-side display unit 10 in which the player P can stand on the floor-side display unit 11 has been described. A mount type stereoscopic display device may be used. Further, in the above-described embodiment, a case has been described where a stereoscopic image that allows stereoscopic viewing is displayed when the stereoscopic glasses 41 are worn, but a stereoscopic image that allows stereoscopic viewing with naked eyes may be displayed.

  In the above-described embodiment, the hit result determination unit 67 performs the collision determination, the determination of the flying direction, the base hit information, and the like based on the positional relationship between the ball object V2 and the bat object V3 in the virtual space. These determinations and determinations may be made based on the positional relationship between the ball image E2 and the dedicated bat 42 in the real space.

  In the above embodiment, the three-surface display unit 10 has three display units (the floor display unit 11, the first wall display unit 12, and the second wall display unit 13) in three directions as viewed from the player P. Although the case has been described, one of them may be omitted. Examples are shown in FIG. 17 and FIG.

  FIG. 17A is a perspective view of the virtual baseball device 1A, and FIGS. 17B and 17C are plan views thereof.

  As illustrated, the virtual baseball device 1A has a two-surface display unit 10A having two flat display units (floor display unit 11A and wall display unit 12A) in two directions. The floor display unit 11A has a triangular shape in plan view. In the illustrated example, the shape of the floor display unit 11A is a right-angled isosceles triangle. As shown in FIGS. 17B and 17C, the wall surface display unit 12A is arranged obliquely in plan view. In the illustrated example, the wall surface display unit 12A is arranged in parallel with the bottom side 11A1 of the floor surface display unit 11A.

  The floor display section 11A and the wall display section 12A may be directly connected, but in the example of FIG. 17, the floor display section 11A and the wall display section 12A are smoothly connected via the curved section 14A having a predetermined radius of curvature. It is connected. The angle formed by the floor surface display unit 11A and the wall surface display unit 12A can be the same angle as the angle β in the three-surface display unit 10.

  In the virtual baseball apparatus 1A, two sets of projectors, ie, projectors 21LA and 21RA for the floor display section 11A and projectors 22LA and 22RA for the wall display section 12A are used. Is displayed.

  As shown in FIG. 17, even when two display units in two directions (floor display unit 11A and wall display unit 12A) are used, the ball is brought close to the player P (for example, a position where the player can hit with the dedicated bat 42). The image E2 can be displayed three-dimensionally, and the player P can perform a batting practice with the same feeling as a batting practice with a real ball, in which the dedicated bat 42 is swung in accordance with the position and timing of the ball image E2. it can.

  In the virtual baseball apparatus 1A, when the turn at bat selection section 62 selects right turn at bat, as shown in FIG. 17B, the direction of the turn at bat image E5 is the direction of the left 12AL of the wall surface display section 12A, and The at-bat image E5 is displayed such that the at-bat image E5R is located within the swing area SR. The pitcher image E1 is displayed on the left side 12AL of the wall display unit 12A. When the turn at bat selection unit 62 selects the left turn at bat, as shown in FIG. 17C, the direction of the turn at bat image E5 is the direction of the right side 12AR of the wall surface display unit 12A (90 times as compared to the case of right at bat). The turn at bat image E5 is displayed such that the left turn at bat image E5L is positioned within the swing area SR. The pitcher image E1 is displayed on the right side 12AR of the wall display unit 12A. Thus, whether the player P is a right batter or a left batter, a bat swing can be safely performed in the swing area SR, and the area of the floor display unit 11A can be reduced.

  The shape of the floor surface display section 11A in plan view does not need to be a triangle. For example, a rectangular shape as shown by a broken line 11A2 may be used.

  FIG. 18A is a perspective view of the virtual baseball device 1B, and FIGS. 18B and 18C are plan views thereof.

  As shown in the figure, the virtual baseball device 1B has a two-surface display unit 10B having two display units in two directions (a floor surface display unit 11B and a wall surface display unit 12B), like the virtual baseball device 1A. The point that the display unit 12B is curved in a plan view is different from the virtual baseball device 1A.

  The virtual baseball device 1B uses the virtual baseball device 1A, the projectors 21LA and 21RA, and the projectors 21LB and 21RB and the projectors 22LB and 22RB similar to the projectors 22LA and 22RA. Like the virtual baseball apparatus 1A, the ball image E2 can be displayed in three dimensions close to the player P (for example, a position where the player can hit with the dedicated bat 42), and the player P matches the position and timing with the ball image E2. It is possible to practice the hitting with the same feeling as hitting with a real ball, in which the dedicated bat 42 is swung.

  As shown in FIGS. 18B and 18C, the method of switching the display of the at-bat image E5 when the at-bat turn selected by the at-bat select section 62 is a right at-bat and a left at-bat is also the same as in the virtual baseball device 1A. It is. Therefore, whether the player P is a right batter or a left batter, a bat swing can be safely performed in the swing area SR, and the area of the floor display unit 11B can be reduced.

  The shape of the floor display section 11B does not necessarily have to be a triangle. For example, a rectangle as shown by a broken line 11B1 in FIG.

  Although the virtual baseball devices 1A and 1B are examples in which one of the first wall surface display unit 12 and the second wall surface display unit 13 is omitted, as another example, the floor surface display unit 11 is omitted and the first wall surface display unit is omitted. Alternatively, a two-surface display unit including two of the display unit 12 and the second wall surface display unit 13 may be used. In this case as well, if the moving path is such that the ball image E2 deviates to the outer corner, the ball image E2 can be stereoscopically displayed close to the player P (for example, a position where the ball image E2 can be hit with the dedicated bat 42). P can practice the hitting with the same feeling as hitting with a real ball, in which the player swings the dedicated bat 42 in position and timing with the ball image E2.

  Further, in the above embodiment, since the dedicated bat 42 is used as the operating body, it is possible to practice the batting using the virtual baseball device. However, if an object other than the bat is used as the operating body, the device may be used. Can be used for purposes other than hitting practice. For example, if the position detecting device 40 detects the position of the catcher mitt using a catcher mitt to which one or more infrared markers are attached as an operating body, it is possible to practice catching a catcher (for example, a bounce or a throw of a ball). A virtual baseball apparatus capable of performing ball catching practice or the like. Similarly, by using other sports equipment (for example, a tennis racket, an ice hockey stick, or the like) having one or more infrared markers attached thereto as an operating body, other sports, such as tennis or ice hockey, can be used. It is also possible to use a device (virtual sports simulation device) for performing a practice or a simulation. A device (virtual sports simulation device) for practicing or simulating other sports (for example, soccer, golf, basketball, cricket, table tennis, badminton, etc.) may be used. Further, for example, by using a net to which one or a plurality of infrared markers are attached as an operating body, it is also possible to provide an apparatus for performing a practice or simulation of insect collection using the net.

  The virtual sports simulation apparatus according to the present invention can be used for, for example, professional baseball, student baseball, youth baseball, or athletes of other sports to practice hitting or catching balls. In that case, the virtual sports simulation device can be installed in a stadium, a practice field facility, a school, or the like. The virtual sports simulation device of the present invention can also be used for game or play purposes. In that case, the virtual sports simulation device can be installed in a game center, a shopping center, an event venue, or the like.

[Appendix 1]
The present application discloses the invention described in each of the following aspects.
<Viewpoint 1>
Object moving means for moving the object in the virtual space;
Display means for generating and displaying an image of the object viewed from a virtual viewpoint in a virtual space for each frame time,
An image display device having a length changing unit for increasing a length of a moving direction of the object according to a moving speed of the object.
<Viewpoint 2>
The object has a spherical main body positioned forward in the moving direction, and a cylindrical extension positioned rearward in the moving direction, and the length changing unit controls the extension according to a moving speed of the object. The video display device according to aspect 1, wherein the length of the image display device is increased.
<Viewpoint 3>
3. The video display device according to claim 1, wherein the length changing unit increases the size of the object according to a moving speed of the object.

  As a method of creating a state in which a real object (for example, a ball thrown by a real pitcher) moves in a CG image, an image of an object moving in a virtual space viewed from a virtual viewpoint is generated and displayed for each frame time. There is a method of doing. In this case, for example, if the object is set to the same size as the object and the object is moved at the same speed as the object, in the generated video, the object on the video is at the same speed as the real ball or at the corresponding speed. Move with.

  However, there is a problem that the difference in the moving speed of the object cannot be sufficiently expressed in the video generated for each frame time. That is, even if the object on the video is moving at the same speed as the real object or at the corresponding speed, the same feeling of speed as the real object cannot be obtained. When the moving speed of the object in the virtual space is high, for example, when the moving distance of the object in one frame time is larger than the size of the object, the object moves discontinuously (jumps) on the video. There is also a problem that it is displayed as if it were.

  To cope with the above problem, it is conceivable to shorten the frame time. However, when the frame time is shortened, there is a problem that the processing load on the computer increases. In particular, in the case of a stereoscopic image, it is necessary to generate images for the left eye and the right eye, so that it becomes more difficult to reduce the frame time.

  In viewpoint 1 of Appendix 1, the length of the moving direction of the object is increased according to the moving speed of the object (for example, in proportion to the moving speed of the object). This makes it possible to more appropriately represent the difference in the moving speed of the object, and also makes it easier for the player to recognize that the object on the video is moving continuously.

<Viewpoint 2>
The video display device according to claim 1, wherein the position adjusting means adjusts the position of the pitcher object such that the start point and the position of the pitcher object in the left-right direction match.

  As a method of creating a state in which a pitcher pitches with a CG image, a virtual model in which a pitcher object performs a pitching motion, a ball object moves at a timing corresponding to the pitching motion is set in a virtual space, and viewed from a virtual viewpoint. There is a method of generating and displaying an image of a virtual model. In this case, since the moving path of the ball thrown by the actual pitcher is various, it is desirable to change the moving path of the ball object in various ways.

  However, when the movement path of the ball object is changed and the hand of the pitcher object performing the pitching motion does not match the position of the starting point of the movement path of the ball object, the ball is released from a position away from the hand of the pitcher. Unnatural images are created. On the other hand, creating motion data of the pitcher object by the number of times at which the starting point of the ball object changes requires an excessive amount of effort.

  In viewpoint 1 of Supplementary Note 2, the position of the pitcher object in the virtual space is adjusted such that the start point of the movement path of the ball object and the position of the pitcher object in the left-right direction match. In a preferred embodiment, the position of the pitcher object is adjusted such that the hand of the pitcher object during the pitching operation coincides with the position in the left-right direction of the movement start position of the ball object. Thereby, a natural image in which the ball is released from the pitcher's hand can be generated.
