Abstract: The present invention provides a screen baseball system including a pitching machine that shoots a baseball, a screen, having a screen hole through which the baseball passes, and a screen shutter including a safety screen configured to close the screen hole. The present invention can fundamentally prevent a safety incident from occurring during a screen baseball game.

Abstract: A method of operating a screen baseball system includes registering a personal rank of a user by a game management unit, displaying a pitching motion on a screen and starting a pitching action according to a selected pitch type, performing a simulation along a trajectory of a batted ball converted from batting detection data of a batter among users, and displaying an image on the screen by the game management unit, photographing a batting image of the batter and storing the batting image in a database by a game photographing unit such that the batting image is utilized for user training and character development programs, and transmitting simulation information and batting image data displayed, to a game shop, in which another user is positioned, in real time by a game server to play a game on line if the another user is positioned in a remote place.

Abstract: A playing method for a screen baseball system includes (a) registering a personal rank, (b) transmitting pitching information section, (c) displaying a pitching motion on a screen if a batter at an offense side presses a pitching pedal, and starting a pitching action according to the selected pitch type, (d) detecting a batting action of the batter and transmitting batting detection data to the game management unit, (e) receiving the batting detection data, converting the batting detection data into a trajectory of a batted ball, performing a simulation along the trajectory of the batted ball, and displaying an image on the screen, (f) photographing a batting image of the batter and transmitting the batting image to the game management unit, (g) receiving and transmitting batting image data and the displayed simulation information, and (h) storing the batting image and game information data.

Abstract: The present invention provides a screen baseball system including a camera module (400) for photographing a struck ball. The camera module (400) includes a pair of cameras (410) including a right camera (411) and a left camera (412), and captures a plurality of images including an image of a struck ball or captures a plurality of images of the struck ball in one image, wherein the longitudinal lengths of the imaging ranges (FL and FR) of the pair of cameras (410) are longer than the transverse lengths thereof and the central axes of the horizontal angles of view of the pair of cameras (41) are angled inward with respect to a parallel line facing the front side. Through this, a locus of a struck ball may be effectively calculated while a dead angle is minimized. Further, the present invention provides a method for simulating screen baseball by using the screen baseball system.

Abstract: The present disclosure relates to a method for playing screen baseball and, more specifically, to a method for playing screen baseball which can be played in a manner similar to a real baseball game by further using a catching position, a ball speed, and a batter level while using a strike zone and a mitt zone along with a pitching mode in calculating the results of pitching.

Abstract: The present invention provides a screen baseball system including a pitching machine that shoots a baseball, a screen having a screen hole through which the baseball shot from the pitching machine passes, and a screen shutter that is provided between the pitching machine and the screen and comprises a safety screen that closes the screen hole. The present invention can fundamentally prevent a safety accident that may occur during a screen baseball game. Even when a user does not recognize or neglects a warning image, the safety accident is prevented.

Abstract: Disclosed is a method for screen baseball using a mobile device. The method comprises (a) confirming whether a user of the mobile device is a member when the mobile device recognizes an identifier image shown on the display of the operator PC; (b) automatically logging in once the user is confirmed to be a member; and (c) controlling the screen baseball in real-time when the user's automatically logged-in mobile device is located in a Wi-Fi area. According to the present disclosure, the user is automatically logged in by recording and simply recognizing the Wi-Fi service set identifier image marked in the operator PC located in the screen baseball system, without installing an additional reader, thereby improving the user's convenience and simplicity as well as the operator's productivity. Additionally, by using the mobile device as a controller of the offense or defense of the screen baseball, the user can change a game plan, etc.

Abstract: Disclosed is an integrated screen baseball platform may include: a mobile character promotion game module that generates ability score information of a character, which has been promoted through a mobile character promotion game, by improving an ability score of the character; a PC management game module that generates management information of a baseball team by executing a PC management game through a user PC; and a screen baseball system that receives management the character ability score information and the management information of the baseball team and adjusts the level of difficulty of a screen baseball game by using any one thereof.
