Description

  The present invention relates to a golf simulator having a function of simulating golf play using data representing an actual golf shot by a player, and more particularly to a golf simulator that can be effectively performed while enjoying the practice of a straight ball.

  Simulators (simulation devices) aimed at simulating experiences such as golf, baseball and shooting are well known in the art. For example, in the case of golf, there is known a golf simulator in which an actual ball and club are used to hit and play toward a golf course projected on a screen. In such a golf simulator, for example, a plurality of cameras are arranged in advance between the shot position of the ball and the screen, and the player hits the ball with a club from a plurality of directions. Based on the above, the motion trajectory of the ball is analyzed by a computer or the like, and based on the analyzed motion trajectory, the state of the ball flying on the golf course in the virtual space is displayed on the screen (for example, Patent Document 1). 2).

  As a technique for analyzing the motion trajectory of the ball, for example, Patent Document 1 calculates the firing speed of the ball (flying object) and the speed of the flying object on each image frame, and the collision of the ball with the screen and the rebound angle. The exact trajectory of the ball so that a realistic simulation of the curved and / or arcuate ball is generated along with the 3D position, firing speed, acceleration and rotation of the ball based on Is estimated. Further, Patent Document 2 recognizes the outer shape of a ball and a club that have been shot multiple times, performs ballistic calculation of the ball in consideration of air resistance, gravity, ball speed, launch angle, spin amount, etc. Calculating the flight position is disclosed.

  On the other hand, simply displaying an accurate trajectory on the screen results in a simple game content. For example, in a shooting game apparatus using a game controller having the shape of a firearm, it is displayed on the screen in order to improve game performance. There is one in which the trajectory is changed (see, for example, Patent Document 3). In Patent Document 3, when a bullet hits one of a plurality of target objects in a shooting game apparatus that hits a plurality of target objects arranged in a three-dimensional game space, for example, another target object is again hit. It has been disclosed to modify bullet trajectory data so that it is difficult to hit.

  In the present embodiment, as a golf shot detection sensor, a radar sensor that uses radio waves (for example, radio waves in a millimeter wave to sub-millimeter wave band) that are reflected by the actual golf ball or club while being transmitted through the screen 11 is used. Yes. The golf shot detection unit (sensor unit) 14 including the radar sensor and the microcomputer is installed behind the screen 11 as shown in FIG. In the golf shot detection unit 14, for example, the launch angle from the shot position of the real ball 3, the initial speed, the three-dimensional position of the ball 3 moving in the real space, the speed, the spin amount (spinning direction and rotational speed), etc. And the detection data is transmitted to the control unit 16.

  The sound output unit 15 includes a speaker, a sound processor, and the like as the sound output means 15a, and is used to output a sound when a player shots a real ball, a sound effect during a golf game, and the like.

  The control unit 16 includes a control unit 16A including a computer 16a and a program 16b executed by the computer. Specifically, the control means 16A is a computer 16a composed of a CPU, an information storage medium, basic software, and the like, actual golf control such as golf progress control in a virtual space linked to a golf shot, and generation and display processing of a simulation image. It includes a program 16b for causing a computer to execute information processing (each procedure) based on shot detection data, various data relating to golf play simulation and golf game execution, and an image processor.

  In the control means 16A, the trajectory of the ball 3 is detected by calculation based on the detection data from the golf shot detection unit 14, and the result of the golf shot of the player 1 is simulated. Then, based on the ballistic data obtained by calculation, the course of the hit ball in the virtual space is determined, and how the hit ball flies in the virtual space and how it falls to the ground of the golf course and stops. An image to be represented is generated, output to the projection unit 12 and projected and displayed on the screen 11.

  In the present embodiment, a batter stands at the shot position in the virtual space corresponding to the shot position of the game room 20 on the golf course composed of the topographic data of the three-dimensional polygon model generated in a pseudo manner in the virtual space. If the virtual camera is set at the viewpoint position assuming that the target object (pin or game target) is captured from that position, the virtual camera view image (in this example, the target object is located at the center of the screen screen) (View image) is generated and displayed on the screen 11. At this time, since the technology for converting from the three-dimensional coordinate system to the two-dimensional coordinate system and displaying it on the screen 11 is a known technology, a detailed description of the image processing is omitted.

  When the golf shot of the player 1 is detected, the control means 16A moves the virtual camera so as to track the hit ball moving in the virtual space, for example, as the control of the virtual camera, and focuses on the tracking target ball. The virtual camera is moved in accordance with the golf shot (ball speed or hit ball) of the player 1 such as taking a video of the field of view including the hit ball captured from the virtual camera while moving the virtual camera to draw a circle behind the ball. I'm trying to control the camerawork.

  In the present embodiment, as golf developed in a virtual space, “simulated golf” and “golf shot game” (both are collectively referred to as “golf game”) in which a play result is determined by one golf shot as described above. ”). However, it is not limited to these golf games, but as a form of simulating golf play for general golf competitions, that is, golf competitions competing for how many hits the ball can be put in the cup Also good. In that case, after the player 1 shots, for example, the shot-falling point in the virtual space is set as a new shot position, and an image of the golf course when the pin direction is viewed from the batter (virtual camera) at that position is displayed on the screen 11. The process of projecting and displaying the above, detecting the next golf shot, and simulating golf play is repeated. Detailed processing in the control means 16A will be described later using a functional block diagram and a flowchart.

  Next, the configuration of the control means 16A will be described.

  FIG. 4 is a functional block diagram for explaining the configuration of the control means 16A according to the present invention. Each means (function) included in the control means 16A is classified by function with a means name for convenience of explanation, and does not limit the software configuration or the hardware configuration.

  In FIG. 4, the control mode switching means 161 is a means for switching the control mode of the golf game developed in the virtual space in conjunction with the actual golf shot. In the present embodiment, the above-described practice mode and game mode are provided as control modes, and a beginner mode and a normal mode are provided as lower modes of those modes. These modes can be switched by operating an operation means (an operation button such as a beginner button) provided in the operation unit 13, and the control mode switching means 161 is operated to switch to the mode by the player. If it is, the golf game control mode stored in the storage means is changed to the mode.

  The trajectory detection means 162 is a means for simulating and detecting the trajectory of a ball shot by a player using a real ball and a club. In the present embodiment, the trajectory detection means 162 receives detection data from the golf shot detection unit 14 (sensor unit), and the three-dimensional position and velocity of the ball 3 moving in the real space included in the detection data. Based on data such as the spin amount (spinning direction and rotation speed), a parabolic trajectory from the shot position of the player 1 to the falling point of the shot ball is calculated by a known arithmetic expression.

  When the control mode is the beginner mode, the virtual board setting means 163 is a virtual board (polygon object) that bounces the hit ball in front of the batter that is assumed to be standing at the shot position in the virtual space. It is a means to perform the process installed so that it may extend along a back direction. The virtual board is a guard plate for relief of miss shots to help beginners' miss shots. For example, a hit ball flies in the OB area, a hit ball hits the ground in front of the eyes, the hit ball rolls on the ground, and jumps out low. It is installed in the virtual space as a direction change plate that rebounds the hitting ball having a trajectory that will be like a drained acrobatics shot and changes the course of the hitting ball to the direction of the target.

  Here, a specific example is demonstrated and demonstrated about the kind and installation place of a virtual board.

  FIG. 5 shows a specific example of the virtual board installed in the beginner mode. FIG. 5A shows the board object 4 (floor board 4a) arranged on the ground side in front of the batter's eye in the virtual space. An example is shown, and FIG. 5 (B) shows an example of the plate object 4 (side plate 4b) arranged on both the left and right sides in front of the batter in the virtual space. 6 shows an example of a golf course image in the normal mode of simulated golf executed in the practice mode (display screen example of the screen 11), and FIG. 7 shows the golf course in the beginner mode of the simulated golf. An example image is shown. As shown in FIG. 7, in the beginner mode, the virtual board 4 that rebounds the hit ball in front of the batter in the virtual space (the same direction as the front of the ball shot position in the game room 20) Installed along the direction. In the present embodiment, as shown in FIG. 6, a golf course image viewed from the batter is a plan view of the course map so that the target (a cup in this example) is positioned at the approximate center of the screen on the screen 11. In the beginner mode, as shown in FIG. 7, an image obtained by converting the floor plate 4a and the side plate 4b arranged in the virtual space from a three-dimensional coordinate system to a two-dimensional coordinate system is displayed on the screen 11 as shown in FIG. Projection is displayed on top.

  The virtual board setting means 163 executes a process for installing the virtual board 4 as shown in FIG. 7 in response to the switching operation to the beginner mode by the player, and the virtual board in response to the switching operation to the normal mode by the player. 4 is executed (processing for switching to the screen in FIG. 6).

  The hitting course correction unit 164 determines whether or not the hit ball hits the virtual plate 4 based on the ball trajectory detection data of the ball detected by the ballistic detection unit 162 and the data of the virtual plate 4 (coordinate data of the polygon object). At the same time, it is means for executing a process of determining a course of a hit ball in the virtual space rebounded by the virtual board 4 when it is determined that the virtual board 4 has been hit. In this embodiment, when determining the course of the hit ball bounced back by the virtual board 4, the process of correcting the hit ball course in the screen center direction (direction of the target) is executed. The details of the hitting course correction process will be described later with reference to the drawings.

  The target placement unit 165 is a unit that is executed when the control mode is the game mode. In the game mode, as described above, as a golf shot game in which elements necessary for actual golf are mini-games, a game that hits a target that is floating in the air with an actual golf shot, or a target set on the green A plurality of types of games are prepared, such as a game in which a hit ball falls in the area.

  As one of those games, how many targets are broken by hitting the target object placed side by side from the front in the virtual space (how many hit the ball penetrates) There is a game to compete (hereinafter referred to as “break shot game”), and the target placement means 165 places the target at the initial position on the screen before the player shots the ball in the break shot game, and the ball is shot. After that, a process of rearranging the target is executed based on the movement speed of the ball in the detected trajectory. The details of the target object rearrangement process will be described later with reference to the drawings.

  The image generation unit 166 is a unit that generates image data to be output to the projection unit 12, and is based on image information (information such as a polygon object modeled in a three-dimensional virtual space, a virtual light source, and a virtual camera). Performs coordinate conversion processing from 2D coordinates to 2D coordinates and rendering processing (image processing by shading, texture mapping, rate racing method, radiosity method, etc.) and game images such as images representing golf course and golf shot results Processing to be displayed on the screen 11 is performed.

  Here, the types of golf games executed by the golf simulator according to the present invention will be described with specific examples.

  FIGS. 8 and 9 are examples of simulated golf screens executed in the practice mode. FIG. 8 shows an example of a screen display screen in the near-pin ball game, and FIG. 8 shows an example of a screen display screen in the Dracon ball game. In the practice mode, for example, a plurality of courses such as beginner, intermediate, and advanced are set so as to be selectable according to the degree of difficulty, so that the player can select them.

  On the other hand, FIGS. 10 to 12 show examples of golf shot game screens executed in the game mode, and FIG. 10 shows an example of a screen display screen in the aforementioned “break shot game”. FIG. 11 shows an example of a screen display screen in a game in which a balloon flowing in the air is shot (hereinafter referred to as “balloon game”), and FIG. 12 shows a ball aiming at a target on the field. An example of a screen display screen in a game to be shot (hereinafter referred to as “bingo shot”) is shown.

  The break shot game shown in FIG. 10 is a game for practicing driver shots. A hit ball is hit against a board 5A (target object 5) as a target arranged side by side from the front to the back in the virtual space. It is a game that competes to determine how many targets will be broken (how many hits the target penetrates). In this game, the target plate 5A (5A1 to 5An) is arranged along the trajectory of a straight ball, for example, so that it becomes difficult to hit the target when the hit ball after the shot becomes a slice ball or a hook ball. The player uses the driver to take a shot of the ball 3 while aiming at the board 5A displayed so as to float on the screen 11. And the faster the moving speed of the ball 3 shot by the player, the more the plate 5 is broken. However, if the direction is bad, the number of plates 5 that can be broken is small even if the distance is large. In other words, it is a game that is practiced to hit a straight ball.

  In this break shot game, it is very difficult for the player to adjust the trajectory with respect to the target. Therefore, the target placement means 165 allows the target to follow the trajectory at the ball detection speed to some extent along the trajectory after the shot. Rearrange the vertical alignment of. That is, as the hit ball after the shot is a straight ball and the flight distance is longer, more targets are cracked and a refreshing feeling can be obtained.

  The balloon shot shown in FIG. 11 is a game for practicing iron shots, and the player uses the iron to hit the balloon 5B flowing in the air. At that time, if you aim for a hardened place or a bomb (a balloon of a specific color), many balloons 5B will break, and the points that the player will get when the balloon 5B breaks due to the color of the balloon 5B To be different.

  The bingo shot shown in FIG. 12 is a game for practicing an approach shot, and the player is a target (target 1 to 9 in this example) 5C on the 3 × 3 square field in FIG. 12 on the green. Aim to hit the ball. Then, the target 5C number is erased, and if the vertical, horizontal, and diagonal lines are aligned, it becomes a bingo. This bingo shot is a game where players compete for points with 3 to 5 balls in one game.

  All of the above-mentioned golf games have a time system of a short time (for example, a time range of 3 to 5 minutes), and the player can freely hit any number of balls with a favorite game (a so-called style of hitting). The player may switch to a favorite game (or a progress control means (not shown) automatically switches based on scenario data) and can freely hit any number of balls in a similar time system. And in beginner mode, it is set as the form which performs the correction process by the above-mentioned hitting course correction means 145. FIG. Further, the play may be performed by one person, or two or more players may alternately compete for points.

  Next, the hitting course correction process in the beginner mode of the control unit of the golf simulator according to the present invention and the target rearrangement process in the break shot game will be described with reference to flowcharts. Note that the processing that has already been described will be omitted or simplified.

  First, the hitting course correction process in the beginner mode will be described with reference to the flowchart of FIG.

  The control unit 16 (hereinafter referred to as “control means”) of the golf simulator 10 changes the control mode of the golf game (the initial value is the normal mode) to the beginner mode when the player switches to the beginner mode. At the same time, the virtual board 4 that rebounds the hit ball is placed in front of the batter in the virtual space so that the board surface extends from the front to the back, and the image (see FIG. 7) is output to the projector and displayed on the screen. Display (step S1).

  Then, when the player shots the ball using the real ball and the club, the golf simulator 10 detects the shot by the sensor 14a of the golf shot detection unit 14 (step S2).

  Here, the detection start operation of the golf shot detection unit 14 will be described.

  The game room door 22 shown in FIGS. 2A and 2C is a door with a key, and the door 22 is provided with a sensor (or a door open / close detection sensor) for detecting the locking / unlocking of the key. It has been. Then, for example, in the form in which the key of the game room 20 is normally locked, the sensor function of the golf shot detection unit 14 in FIG. The locking / unlocking operation of the door 22 with the lock and the sensor function of the golf shot detection unit 14 are interlocked, for example, the sensor function of the golf shot detection unit 14 is stopped in response to the lock detection signal 22. That is, while the player 1 is in the game room 20, the sensor of the golf shot detection unit 14 is operated to be always in a standby state so that the golf shot of the player 1 can be detected at any time. It should be noted that a period during which no detection is performed, such as during advertising or when a menu is selected, may be provided as appropriate.

  When a golf shot is detected in step S2, the control means 16 inputs the detection data of the golf shot detection unit 14 (step S3), and the trajectory of the ball 3 shot by the player 1 based on the detection data. A process of simulating by calculation is executed (step S4). Subsequently, the control means 16 determines whether or not the hit ball hits the virtual plate 4 based on the coordinate data of the virtual plate 4 and the detection data of the trajectory (steps S5 and S6), and determines that it hits the virtual plate 4 In this case, a process of correcting the course of the hit ball bounced by the virtual board 4 in the target direction is executed.

  Here, an example of the correction process of the hit ball course will be described with reference to the drawings.

  FIGS. 14A and 14B show the relationship between the course C before hitting and the course C ′ after hitting (after turning) when the hitting hits the floor plate 4a. FIG. 14A is a plan view, and FIG. 14B is a side view. As shown in FIG. 14A, when the hit ball hits the floor plate 4a, the control means 16 corrects the hit ball course to be in the target direction. In the example of FIG. 14A, correction is performed to change the reflection angle in the horizontal direction to “0 °”. That is, regardless of the horizontal incident angle of the course C (C1, C2) with respect to the surface of the floor plate 4a, the horizontal reflection of the course C ′ (C1 ′, C2 ′) with respect to the surface of the floor plate 4a after the direction change. The angle is changed to “0 °”.

  On the other hand, as shown in FIG. 14B, the vertical reflection angle is such that the vertical reflection angle of the course C ′ (C3 ′, C3 ′) with respect to the surface of the floor plate 4a after the change of direction is the floor plate 4a. The inclination angle is corrected so that the inclination angle becomes A ° (A> the vertical launch angle).

  By performing the process of changing the direction of the hit ball using such a floor plate 4a, even if the hit ball hits the ground in front of the eye or the ball trajectory becomes a low trajectory such as a drained aerobatic shot, the hit ball becomes the floor plate 4a. The hitting course after hitting is changed in the target direction, and it becomes possible to rescue a beginner's miss shot without unnaturalness.

  Next, the correction process when hitting the side plate will be described.

  15A and 15B show the relationship between the course C before hitting and the course C ′ after hitting (after turning) when the hitting hits the side plate 4b. FIG. 15A is a plan view and FIG. 15B is a side view. As shown in FIG. 15A, when the hit ball hits the side plate 4b, the control means 16 corrects the hit ball course to be in the target direction. In the example of FIG. 15A, the horizontal reflection angle of the course C (C4, C5) with respect to the surface of the side plate 4b is an angle B ° (B ° = incident angle / β) different from the incident angle. , I am trying to correct the course of the hit ball.

  On the other hand, as shown in FIG. 15B, when the angle of the vertical direction of the course C (C7) with respect to the side face plate 4b of the hit ball is smaller than the reference angle as shown in FIG. When the vertical angle C ° of (C7 ′) is corrected to be larger than the reference angle, and the vertical angle of the course C (C6) is larger than the reference angle, the course C ′ (C6 ′) after the direction change is performed. ) So that the vertical angle becomes smaller than the reference angle. FIG. 16 shows the relationship between the angle before correction and the angle C ° after correction when performing the correction processing, and the correction coefficient γ in FIG. 16 is set for each type of game.

  Further, as shown in FIG. 17, the speed after the ball hits the virtual board and bounces back is faster when the moving speed of the shot ball is smaller than the set value using the correction coefficient δ. Correction processing for increasing the speed of the hit ball bounced off by the virtual board 4 is performed so that the increase rate is increased.

  As described above, when the hit ball hits the virtual board 4, the control means 16 calculates the incident angle of the hit ball (step S7), and corrects the hit direction of the hit ball bounced by the virtual board 4 to the target direction. At the same time (step S8), the hitting speed is corrected (step S9), and the hitting course after hitting the virtual board 4 is determined (step S10). On the other hand, when it is determined in step S6 that the hit ball does not hit the virtual board 4, the hit ball course becomes the ball trajectory obtained in step S4.

  Then, based on the determined hitting course, an image indicating the result of the golf shot is generated and the image is displayed on the screen (step S11), and the process for the shot is terminated. Thereafter, for example, when a player presses a button such as a game start button (or input of a detection signal by a coin insertion detection sensor, a locking / unlocking detection sensor, or a door opening / closing detection sensor) as a trigger. The elapsed time of the golf game is timed and the end process is executed when the time limit is reached.

  In addition, the inclination angle “A °” of the floor plate described above (A ° = correction coefficient of the vertical angle when hitting the floor plate), and the correction factor “β” of the horizontal angle when hitting the side plate. As shown in FIG. 18, the correction coefficient “γ” for the angle in the vertical direction when hitting the side plate and the correction coefficient “δ” for correcting the speed of the bounced ball are different for each game type. The control means 16 reads the setting value of the correction coefficient corresponding to the game from the storage means, sets the coefficient value in the corresponding arithmetic expression, and executes the hitting course correction processing. .

  Next, the target rearrangement process in the break shot game will be described along the flow of the flowchart of FIG.

  When the break shot game is selected, the control unit 16 projects an image representing the board 5A as a target arranged side by side from the front in the virtual space toward the back as illustrated in FIG. And projected and displayed on the screen 11. (Step S21).

  FIG. 20 is a plan view showing an arrangement example of targets (plate 5A) displayed as an initial screen in step S21. As shown in FIG. 20, the target 5A is arranged in a straight line. Different targets (plate objects) are arranged so that the size of the target 5A increases stepwise as the distance from the shot position of the player increases. The height h of the target 5A from the ground in the virtual space is provisionally arranged so as to increase stepwise (radially) as the distance from the shot position of the player increases. Further, the distance between the targets 5A is 5y when the distance W in the virtual space is 10y (yards) and 17y when the distance W is 7.5y. It arranges so that it may become large in steps.

  When the player shots the ball 3 after displaying the target 5A in step S21, the golf simulator 10 detects the shot by the sensor 14a of the golf shot detection unit 14 (step S22). When the golf shot is detected, the control means 16 inputs the detection data of the golf shot detection unit 14 (step S23) and simulates the trajectory of the ball 3 shot by the player based on the detection data. Processing is executed (step S24).

  Subsequently, the control unit 16 executes a process of rearranging the target 5 </ b> A based on the moving speed of the ball 3. In the present embodiment, the vertical arrangement of the targets 5A is rearranged after the shot so that each target 5A follows the trajectory at the moving speed of the ball 3 to some extent (step S25).

  Here, the relocation process of the target 5A in step S25 will be described with reference to the drawings.

  FIG. 21 shows a pattern of rearrangement of the target 5A. The height position of the target 5A is set in advance by a plurality of patterns, and which pattern is used is determined by the moving speed of the ball 3. To do. In the example of FIG. 21, pattern 1 in which each target is rearranged at the reference ballistic height when the ball speed is 30 m / s or less, and the reference ballistic height when the ball speed is 30 to 40 m / s. Pattern 2 for relocating each target, Pattern 3 for relocating each target to the height of the standard trajectory when the ball speed is 40-50 m / s, Reference trajectory when the ball speed is 50-60 m / s A total of five patterns were preset: pattern 4 for rearranging each target at a height of 5 and pattern 5 for rearranging each target at the height of the reference trajectory when the ball speed was 60 to 70 m / s An example is shown. For these five patterns, for example, each target is placed on the trajectory determined by the conditions (ball speed, launch angle (vertical angle), back spin amount, side spin amount = “0”) in FIG. A table storing the coordinate data of the target 5A group where the center of 5A is located is stored in the storage means.

  In step S25, the control means 16 compares the movement speed of the ball 3 with the speed range of each pattern, reads out the coordinate data of the target group of the pattern corresponding to the movement speed of the ball 3 from the storage means, and uses the pattern as the pattern. Relocate target 5A group. For example, when the detection speed of the ball is 35 m / s, the coordinate data of the target group of the pattern 2 in FIG. 21 is read from the storage means, and as shown in FIG. Each target 5A is rearranged so that the center of the target 5A is located.

  Subsequently, it is determined whether or not the hit ball hits the target 5A based on the trajectory data detected in step S24 and the coordinate data of the rearranged target 5A group (step S26). Then, the determination process is repeated for each target 5A, and for the target 5A determined to have been hit, an image representing how the target 5A breaks is generated and displayed on the screen 11, and the effect representing the sound that the target breaks is also produced. A sound is output (step S27), and the process for the shot is terminated. The hit ball is configured to continue the movement on the trajectory detected in step S24 even after hitting the target 5A without decreasing the speed due to the collision of the target 5A.
