Description

Screen baseball game system and its driving method{SCREEN BASEBALL GAME SYSTEM AND DRIVING METHOD THEREOF}

The present invention relates to a screen baseball game system, and more particularly, to a screen baseball game system and a driving method for constructing a screen using a beam projector and proceeding a sensational game by hitting a ball by a user directly entering a turn at bat. .

Baseball is a ball game in which a pitcher hits the ball thrown by a batter using a bat to survive as a base, and is a popular sport that requires the basic skills of physical education. Since it uses four bases of first base, second base, third base, and groove, it is also called a baseball.

Generally, since baseball requires a relatively large space with a certain number of people, there are human, temporal, and spatial restrictions for the general public to freely enjoy a baseball game.

In order to overcome the above-described limitations, hitting ranges having pitching machines have been proposed. However, in the case of a general hitting range, it is impossible to select a limited pitch or respond to various environments, and there is a disadvantage in that a considerable space is required even if it is not the actual size of the stadium. In addition, since the game of one-sided hitting progressed, there was a limit in that the sense of reality and fun, such as strike or out or score acquisition, were significantly reduced.

Accordingly, a screen baseball game system that can be enjoyed indoors has been developed, and conventional screen baseball game systems are provided with a screen on which an image is displayed by a beam projector on the front side, similar to a screen golf system, and provided on one side of the center of the screen at the back of the screen. It is common to use a pitching device that throws a ball through a through hole and a sensor device that can grasp the coordinates of a ball hit between the screen and the batter's seat.

Here, as a sensor device, in the form of a rectangular frame with an empty center, a light emitting unit that transmits light or a signal is installed on one side, and a light receiving unit that receives the transmitted light or signal is installed on the other side to match 1:1. The method of reading the position where the ball obscures the light, or the camera is installed indoors to shoot the ball and perform image processing to calculate its coordinates is widely used.

1A and 1B are diagrams for explaining a ball detection method of a conventional screen baseball game system.

First, referring to FIG. 1A, as a screen baseball game system to which an infrared detection method is applied, one or more infrared light emitting units 11 and 13 are installed on one side of the room 10, and the infrared light receiving units 12, respectively, are matched to each other. 14) shows how to extract the three-dimensional coordinates (x,y,z) of a baseball passing through two sides. According to such an infrared detection method, it is possible to measure the speed, direction, and trajectory of the ball, and has an advantage of being able to implement a simple algorithm with high accuracy. However, it is impossible to analyze the pitch of the pitch and the position where the ball starts when hitting, and the shorter the reaction speed of the ball in the simulation is, the farther it is from the turn at the sensor. The disadvantage is that this is difficult.

In addition, referring to FIG. 1B, as a screen baseball game system to which the camera photographing method is applied, two cameras 21 and 22 are installed on the ceiling of the room 20, and through this, the ball is photographed from the upper part to the areas A and B. By comparing and analyzing 2 to 3 images through the measurement at the time of hitting in the overlapping area, it shows the configuration of extracting x,y,z coordinates. According to such a camera photographing method, there are advantages of high directional accuracy, speed and trajectory measurement, and swing and foul measurement.

However, the ballistic measurement is inaccurate, resulting in an error in the speed of the batting ball, the analysis of the pitch is impossible, and there is a limit to be inferred by analyzing the ball starting position at the time of batting. In addition, there is a disadvantage in that an error occurs in a part where the ball and the bet overlap the upper part of the turn at bat. In addition, in the camera shooting method, as the image processing algorithm and the performance of the camera generally determine the detection result, there is a problem that the construction cost is high and difficult to implement.

The present invention has been devised to solve the above-mentioned problems, and the present invention not only can accurately analyze the movement of the moving ball, but also performs measurement on the pitched ball hit by the user and the ball moving in the user's direction. Therefore, there is a problem in realizing a more accurate baseball game simulation.
