Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention hits a real club and ball for competition in a narrow space, detects the X-coordinate and the Y-coordinate of the hit ball on a predetermined detection surface, and outputs the detection data. The present invention relates to a golf simulation game device which inputs into a computer, drives golf game simulation software, displays a scene of a play on a golf course on a screen, and can enjoy the same excitement as in reality.

[0002]

2. Description of the Related Art Conventionally, as a golf game simulation device, there is a device for hitting a golf ball toward a screen as disclosed in Japanese Patent Laid-Open No. 2-209168, and many such devices have been proposed. ing.

A trajectory calculation device that uses a video camera as a detector to determine the flight state of a ball launched from the tee and calculates the trajectory of the ball has also been cited as a prior art and disclosed together.

[0004]

In the conventional golf game simulation apparatus, the most difficult thing depends on how to detect the data from the hit ball. In particular, it is not possible to determine an accurate trajectory of a flight only by measuring a passing ball with a video camera, and it is not possible to enjoy a true golf game simulation.

Therefore, in the present invention, the X-axis and the Y-coordinate of the hit ball are detected on the front and rear detection surfaces in the flight direction,
This is input to a computer, the three-dimensional vector amount of the hit ball is detected, that is, the size, direction, and speed, the golf game simulation software is driven based on these data, and a video projector plays a scene on the golf course. Is displayed on the screen so that the player can enjoy the game with the same feel as hitting a golf game on a golf course.

The method of detecting the three-dimensional vector amount of the hit ball can be carried out by detecting the X coordinate and the Y coordinate on the detection surface of the ball 7 hit from the golf club, which is spaced apart in the hitting direction.

By calculating the Y coordinate Dy1 of the detected data by the equation as shown in FIG. 5, the moving elevation angle θr of the ball 7 which has passed can be obtained. The obtained data is temporarily stored in the personal computer because it is used for various calculations thereafter.

Next, the initial velocity measurement of the ball 5 hit from the golf club can be obtained, for example, by detecting the time between the X coordinate and the Y coordinate and calculating this. The true ball speed is obtained by dividing the moving amount of the sphere by the required time t, and the moving amount is represented by a vector of the distance d between the detection surfaces, the height difference Dy1, and the left-right difference Dz, as shown in the formula in FIG. Become.

Origin of launch (position of tee in this case)
And the Y-coordinate detector for detecting the Y-coordinate are set to a required interval.

Next, the reaching distance and the reaching point of the ball hit from the golf club are calculated by adding the detected data of the X coordinate in addition to the calculated launch angle and initial velocity to obtain the reaching distance. Can be displayed on the display. In this case, it is possible to produce a game variation by introducing factors such as gravity, air resistance, wind direction, and wind force to perform calculation. As a result, the decision of the arrival point has a wide range, and it becomes more interesting than simply selecting the arrival distance.

Next, the horizontal angle of the ball hit from the golf club can be measured by setting an X coordinate detector for detecting the X coordinate immediately before the screen as shown in FIG. The X coordinate detector detects the horizontal passing coordinate of the ball. The horizontal launch angle can be obtained by calculation with the origin (in this case, the hit point) coordinates. That is, in a view of the ball viewed from directly above, the distance Lo between the ball origin and the left and right X coordinate detectors Z and the X coordinate detector Z
The left and right blur angles θz based on the detection data Dz of Eq.

Next, regarding the measurement of the spin of a ball hit from a golf club, it is usual that the hit ball of a golf ball is given a certain rotation at the moment of hitting to fly. Then, after flight, it hits the screen, repels due to the tension of the curtain, and moves in the opposite direction. As for the ball, if you set the X coordinate detector just before the screen as described above,
The X coordinate detector is passed twice, before and after hitting the screen. Depending on the horizontal component of the ball's rotation,
The repulsion direction from the screen is changed, and the incident angle coordinate and the reflection angle coordinate do not always match. By calculating the passing coordinates before hitting the screen and the passing coordinates after hitting the screen, so-called slice and hook strengths can be calculated. Then, this spin detection data is intended to be used for image processing.

That is, in FIG. 8, in the case of a straight ball, since the incident angle and the reflection angle with respect to the screen are equal, the ball hit out passes through the point A and then bounces on the screen through the point C, but when the hook rotates. Is B
In the case of point or slice rotation, it passes through point D. In this way, it is possible to detect hooks or slices by measuring how far the ball bounced off the screen passes from the trajectory of the straight ball. The distance between the ball launch position and the X coordinate detector is a, the distance between the X coordinate detector and the screen is d, the incident angle data is ZA, the reflection angle data is ZB, and the reflection angle data for a straight ball is ZS. Then, the positional deviation ΔZ between the straight and the reflecting ball is ΔZ = ZS−ZD = (2d / a + 1) ZA−ZB, and when ΔZ = 0, when straight ΔZ> 0 and when hook ΔZ <0 The slice is detected.

Next, depending on how the X and Y coordinates are to be detected, an infrared projector and an infrared receiver are used.

Since the infrared light receiver is sensitive only to light in the infrared wavelength range, when the infrared light from the light emitter is blocked, a change occurs and a detection signal is obtained. It can be said that there is almost no risk of malfunction because the infrared level is quite low in a normal room.

When the infrared projector and the infrared receiver are used for detection, if a plurality of them are arranged on a plane and it is desired to know the position of the detected object, the detected object is detected as shown in FIG. If it is between the light emitter L-3 and the light receiver S-3, S
The detection signal should be obtained from -3.
Also, the rays from L-4 also enter S-3 at the same time, so no detection signal can be obtained.

In the light receiving device for simultaneously operating the plurality of light receivers, light from other light projectors is incident on the light receiver that can detect the object to be detected, and in order to avoid this, several adjacent light projectors are used. It turns out that it suffices not to turn on. That is, in FIG. 4, one of the 32 light projectors whose tail numbers are commonly connected to the signal from the high-speed sequential lighting circuit is turned on, and the other light emitters are not turned on. Similarly, if the detection signal of the light receiver is synchronously controlled by the lighting signal, it can be detected that the golf ball has passed between the specific light projector and light receiver.

Although the present invention is theoretically established as described above, there are some problems in actual implementation. Generally, the maximum ball speed of a golf ball is 80 m / s
(288km / h), but the ball speed is 80m /
The time during which a golf ball having a diameter of 40 mm and a diameter of 40 mm obliquely illuminates the light receiving device is T = 40 × 0.001 / 80 = 500 μs, and therefore one SCAN time must be 500 μs or less. For example, an emitter / receiver with an SC for every 32 elements
When configured to repeat AN, the operating time of one element is: t = 500 μs / 32 = 15 μs = 64 KHz.
Therefore, when the 80 m / s golf ball passes through the emitter / receiver scanning at 64 KHz, it is detected only once. (The following description will be made under the condition that the number of emitters / receivers is 32 elements.) In the case of emitters / receivers, the following two new problems arise when scanning one element at a higher speed of 64 KHz or more. It happened. 1. If the photoreceiver is configured with phototransistors, it cannot respond to frequencies above 64 KHz. 2. When the LED of the projector is blinked at 64 Hz or more
Photocurrent is 5mA when the distance of the light receiver is within 100mm
The above can be obtained, but when the distance between the light emitter and the light receiver is 1000 mm or more, the photocurrent becomes about 1/170 or less of that at 100 mm. For this reason, the detection sensitivity is extremely lowered and the desired signal does not appear in the light receiver.

Problem 1 is that a photodiode that can respond at a higher speed than a phototransistor is used as a light receiving element, and the low detection sensitivity of the photodiode is obtained by combining a high gain and high speed amplifier. Settled. The problem 2 was solved by using a plurality of projector LEDs and compensating for the decrease in the light amount due to the distance.

[0020]

A required ball hitting space between a hitting position of a ball hitting a screen and a screen is defined by horizontal X-coordinates in the horizontal direction and vertical Y-coordinates in the vertical direction. The X-coordinate detector and the Y-coordinate detector for detecting are formed of a light emitter and a light receiver which correspond to each other, and the light emitter and the light receiver are arranged in a left-right direction and a vertical direction at a required parallel interval in multiple stages. , A multi-channel photo driver that inputs and outputs a scanning signal of a multi-channel register that operates at a required clock for these projectors, sequentially emits light, and causes a light receiver corresponding to the projector to receive light emitted from the projector, The change of emitted light blocked by passage is detected by the multi-photodetector, and this is output as a binarized value by the multi-comparator. An output detected by the parallel / serial scan decoder in synchronization with the corresponding light projector is output in series, and the X- and Y-coordinates on the detection surface of the hit ball are detected by this output. There is a golf game simulation device in which a golf game simulation software is input and a video projector displays an image as a golf game scene.

The projector and the receiver constituting the X-coordinate detector are installed at required positions in front of the screen, the incident angle and the reflection angle of the hit ball on the screen are detected, and the detected data are input to the personal computer. However, this may be processed.

[0022]

Since the present invention is as described above, it becomes possible to detect the trajectory, speed, and spin of a hit ball accurately by detecting light at high speed and with high sensitivity by a light transmitter and a light receiver corresponding to each other. is there.

Further, by arranging a high-speed and high-sensitivity light emitter and light receiver at the above-mentioned positions, data of the hit ball is detected as a three-dimensional vector amount (size, direction, speed), and the golf game simulation software It is possible to adapt.

According to the device of the present invention, the player can use the club and the ball that he or she normally uses, and can play in the same scene atmosphere as the golf course, and with the same feeling of hitting the ball as when playing the game. It is possible.

In addition, the total number of hit balls and the total number of handicap numbers can be computer-processed to completely automate the game play.

[0026]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the embodiments shown in the drawings. As shown in FIGS. 1 to 3, a golf game simulation apparatus space having a required height, width and height on an indoor floor surface 1. 2 is provided, and a play field 4 of a hit area 4a centered on the tee 3 and a hit area 4b in which the hit ball 5 hits is provided near the front part thereof, and a golf field is provided at the rear end which is the end of the play field 4 A screen 6 that doubles as a field projection and a hit ball buffer is erected, and a video projector 7 is arranged above the front part. The video scene of the golf course is projected by the video projector 7.

In the flight area 4b where the hit ball 5 flies, a light projector L and a light receiver S whose detection optical axes correspond to the left and right horizontal directions are vertically arranged at required intervals, for example, two half of a golf ball. The Y coordinate detectors 8 are arranged in parallel with a space of centimeters.

Immediately in front of the screen 6, a projector L and a light receiver S whose detection optical axes correspond to each other in the vertical direction with a required interval.
Are arranged in parallel at a required interval on the left and right, for example, at an interval of 2 cm, which is a half of a golf ball, and an X coordinate detector 9 is provided.

The Y coordinate detector 8 and the X coordinate detector 9
The light projector L and the light receiver S constituting the above are detected by the circuit of the block circuit diagram shown in FIG. The X coordinate detector 9 will be described in detail. The light emitter L and the light receiver S correspond to the upper and lower sides, and the length of the four meters is divided from left to right, for example, into 6 as shown in FIG. The projector L and the light receiver S are divided into sections, for example, in one section, L-1-1, S-1-1, and L-
-1-2 and S-1-2, L-1-3 and S-1-3, L-1-32 and S-1-32 are provided in the same manner in the two sections. -1 to S-2-1, the light-emitting device L-2-32 and the light-receiving device S-2-32 are arranged, and the three sections, the four sections, the five sections, and the six sections are the same. A high-speed sequential floodlight lighting circuit CH is connected so that each floodlight is turned on only for one light emitter and the other floodlights are not turned on for each floodlight. (CH-A, CH-B, CH-F in FIG.
-C to CH-E are omitted.) A high-speed sequential photoreceiver drive circuit ch is connected to each photoreceiver. Then, in synchronization with the corresponding light projector, only one light receiver is driven for each section, and other light receivers do not operate. (Similarly, in FIG. 4, ch-a, ch-b, and ch-f indicate each section, and ch-c to ch-e are omitted.)

A section CH-A of the high-speed sequential light-emitter lighting circuit CH sequentially receives light by a 32-channel photo driver CH-A2 which inputs and outputs a scanning signal of a 32-channel register CH-A1 which operates at a required clock. LED) L-1-1 emits infrared rays. The light receiving device S-1-1 corresponding to the light projecting device L-1-1 receives the infrared light of the light projecting device, receives the change of the infrared light blocked by the passage of the hit ball, and detects the change by the 32-channel photo detector ch-a1. The 32-channel comparator ch-a2 outputs a binarized value, and the binarized value output is output to the parallel / serial scan decoder ch-
The outputs detected in synchronization with the corresponding projectors L-1-1 by a3 are sequentially output in series, and the detection outputs are input to a personal computer to obtain the X coordinate, the Y coordinate, and the X coordinate on the detection surface of the hit ball. The time to pass to and from the Y coordinate is detected. Thus, the three-dimensional vector amount of the hit golf ball is detected.

The data thus detected is arithmetically processed in a personal computer (not shown) to calculate the actual reaching distance, and at the same time, the scene of the ball reaching at the playing golf course is projected on the screen by the golf simulation software. Therefore, it is possible to hit the ball in the hit area 4a toward the screen and play the golf game in the same atmosphere as in the actual scene.

In the above-mentioned embodiment, the X coordinate detector and the Y coordinate detector are illustrated at one location, respectively. However, by arranging the X coordinate detector and the Y coordinate detector at two locations before and after, for example, a projector that constitutes the Y coordinate detector. It is possible to install the light receiving device and the light receiving device at two positions appropriately separated from each other between the hitting position and the screen, and the first Y coordinate and the second position of the hitting ball on the respective installation detection surfaces.
It is also possible to detect the Y-coordinate and input the detected data to the personal computer. By doing so, the hitting position can be freely set and the accuracy of measurement can be improved.

[0033]

[Effect] Since the present invention is as described above, it is possible to eliminate erroneous detection and erroneous operation that were inherent in conventional golf game simulations, and succeed in developing a high-speed and high-sensitivity photodetector. It is now possible to detect the trajectory, speed, and spin of a hit ball.

Further, by arranging a high-speed and high-sensitivity photodetector at a required position, the hit ball is converted into data as a three-dimensional vector amount (size, direction, speed), and more accurate flight ball calculation is performed. It also contributes to docking with golf game simulation software.

Thus, according to the device of the present invention, since no special ball or club is required, the player can use the club and ball that he or she normally uses.
It is something that can be played, much like playing a game on a golf course.
