In step S12, image processing of the acquired image data by the CCD camera is executed. Here, the trajectory of the ball 20 is analyzed from the image data transmitted from the first CCD camera 31 and the second CCD camera 32.
In step S13, it is determined whether or not the ball 20 has collided with the front wall 11. Based on the analysis result of the image data by the image processing unit 62, it is determined whether or not the ball 20 has collided with the front wall 11. If it is determined that the ball 20 has collided with the front wall 11, the process proceeds to step S14. To do.
[0022]
In step S14, a game loop by the game execution unit 60 is started.
In step S15, the game result in the game loop is displayed.
The process of the game loop in step S14 is shown in the flowchart of FIG. When the game loop process is started, a game screen 111 as shown in FIG. 9 is generated and projected onto the front wall 11 via the projector 40. The game screen 111 is composed of a composite image obtained by combining the background screen and the objects 112 and 113 that are the target when the player strikes the ball 20 based on the image data read from the storage unit 54. The game screen 111 includes a stage display unit 114 indicating the current stage number, a score display unit 115 that displays the score of the player, a life display unit 116 that displays the number of lives of the player, and the like.
[0023]
In step S21, image data is captured by the CCD camera. Here, the image data acquisition unit 61 acquires the image data transmitted from the first CCD camera 31 and the second CCD camera 32 at a predetermined timing.
In step S22, image processing of the acquired image data by the CCD camera is executed. Here, the trajectory of the ball 20 is analyzed from the image data transmitted from the first CCD camera 31 and the second CCD camera 32.
In step S23, it is determined whether or not the ball 20 has collided with the front wall 11. Based on the analysis result of the image data by the image processing unit 62, it is determined whether or not the ball 20 has collided with the front wall 11. If it is determined that the ball 20 has collided with the front wall 11, the process proceeds to step S24. To do.
[0024]
In step 24, position information of the ball 20 when the ball 20 collides with the front wall 11 is acquired. Here, the position information of the ball 20 at the contact timing specified by the image processing unit 62 is acquired from the image data of the first CCD camera 31 and the second CCD camera 32, and based on this, the virtual position information of the ball 20 in the game screen is obtained. A certain collision coordinate B (x, y) is calculated.
In step S25, it is determined whether or not the objects 112 and 113 that are the target of the collision coordinates B (x, y) of the ball 20 exist. In the determination unit 64, the position information of each object 112, 113 transmitted from the game execution unit 60 is compared with the collision coordinate B (x, y) of the ball 20, and the object is detected at the collision coordinate B (x, y). If it is determined that it exists, the process proceeds to step S26.
[0025]
In step S26, a collision process when the ball 20 collides with the object is executed. In the collision process, the score corresponding to the type of the target hit by the ball 20 is added to the score of the player, and the display of the score display unit 115 is updated. Further, damage display is performed on an object determined to have hit the ball 20. For example, as shown in FIG. 10, when it is determined that the ball 20 has hit the object 112, a damage display 117 for displaying this is displayed. Further, for an object that has reached the maximum damage, an image that explodes or disappears is generated and combined and displayed on the game screen 111. It is also possible to configure the player to attack the player from the object displayed on the game screen 111. For example, the object is configured so that the object approaches the player side with time on the three-dimensional coordinates of the game screen. Applying damage to the object by hitting the ball 20 against the object before approaching the position of the player can be a normal for the player. For example, as shown in FIG. 11, when the object 112 is close to the player position, it is assumed that the object 112 has been attacked, and the game screen 111 is flashed to indicate that it has received damage. The number of lives displayed on the display unit 116 is reduced by one.
[0026]
When the game is over, the game result is announced (step S15 in FIG. 6). For example, a result announcement screen 121 as shown in FIG. 12 can be displayed. Here, the result announcement screen 121 is a target number display section 122 that displays the number of defeated enemies, a score display section 123 that displays the total score of the player, and a calorie display section 124 that displays the calories consumed by this exercise. And a rank display unit 125 for displaying a ranking based on the total score of the player. The data displayed on each display unit is calculated based on the game play of the player during the game loop process, and the calculation result is displayed on each display unit.
[0027]
A game can be played by one player, and two or more players can alternately hit the ball 20 and play the game. When a game is played by two or three or more players, it can be configured to determine which player's score is based on the number of times the ball 20 contacts the front wall 11.
In such a game apparatus, a projector 40 is attached to the ceiling 15 such as a squash court or a racket ball court to project the game screen 41 on the front wall 11, and the CCD cameras 31 and 32 are applied to the sidewall 13 (12) and the ceiling 15. By detecting the collision coordinates of the ball 20 with the front wall 11 by attaching, it becomes possible to easily enjoy the game. Therefore, it is possible for anyone to play sports like a game, exceeding the age difference and ability difference, as compared to simply playing sports such as squash and racquetball.
[0028]
The projector 40 and the CCD cameras 31 and 32 can be configured to be supported at a predetermined height by a support tool placed on the floor. In this case, the installation is easier and the game can be played without selecting a place. For example, if there is only a wall surface corresponding to the front wall 11, a game can be played, and a game can be played using an inner wall of a gymnasium or an outer wall of a building.
In addition, this game device can enlarge and reduce the screen, and can be applied not only to a wide space such as a gymnasium but also to a game using indoor walls such as a general home. For example, it can be applied to table tennis using an indoor wall, and a single device can be used in various places.
[0029]
[Second Embodiment]
FIG. 13 shows a schematic configuration of the second embodiment.
Instead of the first CCD camera 31 and the second CCD camera 32 used in the first embodiment, a first CCD camera 91 and a second CCD camera 92 are used.
The first CCD camera 91 and the second CCD camera 92 can each be directly installed on the floor 14. The first CCD camera 91 is installed at the lower left of the front wall 11 and shoots image data centered on the upper right direction. The first CCD camera 91 is configured so that a scale 93 indicating the position in the P-axis direction parallel to one diagonal line of the game screen 41 is reflected. The second CCD camera 92 is installed at the lower right of the front wall 11 and shoots image data centered on the upper left direction. The second CCD camera 92 is configured so that a scale 94 indicating the position in the Q-axis direction parallel to the other diagonal line of the game screen 41 is reflected.
[0030]
The configuration of the second embodiment is substantially the same as that of the first embodiment except that the first CCD camera 31 and the second CCD camera 32 in FIG. 2 are replaced with the first CCD camera 91 and the second CCD camera 92.
The operation in the game loop of the second embodiment will be described based on the flowchart of FIG.
In step S21, image data is captured by the CCD camera. Here, the image data acquisition unit 61 acquires the image data transmitted from the first CCD camera 91 and the second CCD camera 92 at a predetermined timing.
[0031]
In step S22, image processing of the acquired image data by the CCD camera is executed. Here, the trajectory of the ball 20 is analyzed from the image data transmitted from the first CCD camera 91 and the second CCD camera 92.
In step S23, it is determined whether or not the ball 20 has collided with the front wall 11. Based on the analysis result of the image data by the image processing unit 62, it is determined whether or not the ball 20 has collided with the front wall 11. If it is determined that the ball 20 has collided with the front wall 11, the process proceeds to step S24. To do.
[0032]
In step 24, position information of the ball 20 when the ball 20 collides with the front wall 11 is acquired. Here, the position information of the ball 20 at the contact timing specified by the image processing unit 62 is calculated from the image data of the first CCD camera 91 and the second CCD camera 92. Here, the P axis and the Q axis in the image data of the first CCD camera 91 and the second CCD camera 92 constitute independent coordinate axes, and the position information of the ball 20 is virtual position information in the game screen 41. It is possible to convert the collision coordinate B (p, q) to the horizontal axis X and the vertical axis Y of the game screen 41 from the collision coordinate B (p, q). Therefore, the position information acquisition unit 63 obtains the collision coordinates B (x, y) from the collision coordinates B (p, q) by coordinate conversion. Thereafter, the game loop process is executed in the same manner as in the first embodiment.
[0033]
In the second embodiment configured as described above, the first CCD camera 91 and the second CCD camera 92 can be directly installed on the floor 14, the installation is easy, and a game can be easily enjoyed.
[Other Embodiments]
A) In the above-described embodiment, the squash or racket ball racket and the game using the ball are exemplified, but it is possible to produce games in various forms by combining with other sports or games. .
[0034]
For example, a form in which a tennis ball is hit against a wall surface with a tennis racket can be assumed. It is also possible to assume a form in which a baseball is thrown toward a wall surface. Further, it is possible to assume a form in which something other than a ball such as a frisbee or an arrow is emitted toward the wall surface.
B) The method of detecting the timing at which the ball 20 collides with the front wall 11 and the position at which the ball 20 collided can be implemented using other sensing techniques.
For example, assuming a plane parallel to the front wall 11, a plurality of pairs of light-emitting elements and light-receiving elements for detecting the position of a ball crossing the plane can be arranged in a matrix.
[0035]
Further, it is possible to attach a pressure sensor to the entire surface of the front wall 11 and detect the collision coordinates of the ball 20 based on the detection signal of the pressure sensor to obtain position information.
C) A plurality of CCD cameras can be installed in the court, and the position information of the ball 20 in the court can be detected three-dimensionally. For example, at least one of the sidewalls 12 and 13 and at least one of the floor 14 and the ceiling 15 are provided with a CCD camera for photographing the moving ball 20 and image analysis of each CCD camera is performed. The three-dimensional position information of the moving ball 20 can be sequentially detected. In this case, even when the object in the game screen is away from the front wall 11, it is possible to determine that the ball 20 has hit the object, and a game in a virtual three-dimensional space is provided. can do.
[0036]
Further, it becomes possible to specify the current speed of the ball 20 based on the three-dimensional position information of the ball 20 obtained from a plurality of CCD cameras, and the impact on the object in the game image according to the speed of the ball 20. It is also possible to adopt a configuration that changes the degree and damage.
For example, for the movement of the ball 20 toward the front wall 11, the time from the distance 3 m in front of the front wall 11 to the distance 1 m in front is calculated, and by dividing the distance 2 m between the points by this time, the speed per unit time Is calculated. When this speed is equal to or higher than a predetermined speed, for example, the explosion flame size is increased and the obtained score is further increased in order to increase the damage to the object. The position at which the velocity of the ball 20 is measured is not limited to the above, but the ball 20 is considered to be in front of the front wall 11 in consideration of the velocity calculation time in order to reflect the result of velocity calculation on the game screen in a timely manner. It is preferable that the speed calculation is performed not until the moment of collision with the vehicle, but until it is reached.
[0037]
In addition, using the three-dimensional detection for the game effect, for example, when the ball 20 reflected from the front wall 11 bounces twice on the floor, an effect is made in which the player's damage progresses at once and the game ends. For example, the movement of the ball 20 reflected from the front wall 11 can also be reflected on the game screen, thereby enabling various effects. It is also possible to change the effect of the image displayed on the front wall in synchronization with the movement of the ball 20. For example, depending on the speed and moving direction of the ball 20, the color change and brightness Various effects such as changing the background and changing the background display image are possible.
D) In addition to the front wall 11, it is possible to display game images on the side walls 12, 13, the floor 14, the ceiling 15, the back wall, etc., and display the game images on two or more surfaces to play the game. It can be configured as follows.
E) The display method of the game image is not limited to the image projection by the projector, and various forms can be assumed. Although it is not as portable as the projector type, it can be carried anywhere, but it can take the following forms.
[0038]
For example, a display device such as a flat CRT, a liquid crystal display panel, or a plasma display may be installed on the front wall 11 to display a game image. In this case, it is conceivable to protect the display device by providing a tempered glass or a transparent acrylic plate on the front surface of the display device.
It is also possible to project the game image from behind on a screen stretched in space. In this case as well, it is conceivable to protect the screen by providing a tempered glass or a transparent acrylic plate on the front surface of the screen. Of course, these examples can also be carried around if the screen is relatively small as in a table tennis game.
[0039]
Further, as an example of slightly more portability than the above, it is possible to project a game image on a smoke screen provided in a space. In this case, it is possible to play a game by opposing players such as tennis or volleyball. In addition, games can be played even in gymnasiums, tennis courts, and other places where there are no walls.
[0040]
【The invention's effect】
In the present invention, the game image is displayed by the image display means using the wall surface of the exclusive court of squash or racquetball, the inner wall of the gymnasium, the outer wall of the building, etc. as the display surface, and the player or the other moving body is directed toward the game image By releasing, you can easily enjoy sports like a game.
