Abstract: Disclosed are an experience-oriented virtual baseball game apparatus that enables a user to practice baseball or play a baseball game with a virtual player in a virtual baseball image projected on a screen based on the virtual baseball image, configured such that the user experiences a very interesting war of nerves between a pitcher and a batter, for example, the user pitches a ball toward the screen in order to induce a virtual batter in the image to ground out or to fly out through the location of his/her pitch or the virtual batter makes a hit or hits a home run due to a careless pitch of the user, through the baseball game, and a virtual baseball game control method using the same.

Abstract: Disclosed are a ball-pitching control method of a pitching machine in a baseball practice system that is capable of automatically compensating for inclination of the pitching machine, which may occur depending on the installation environment of the pitching machine, based on the result of sensing performed by a sensing device for sensing a pitched ball or a hit ball without using a separate sensor or measurement device and that is capable of automatically self-correcting the displacement of the pitching machine from the original position thereof or the corrected position thereof over time due to external impact applied to the pitching machine or a manager's inaccurate correction of the pitching machine by analyzing the results periodically sensed by a sensing device and the cumulative results of set ball pitching information of the pitching machine, and a baseball practice system using the same.

Abstract: Disclosed are a ball-pitching control method of a pitching machine in a baseball practice system that is capable of sensing a pitched ball or a hit ball using a sensing device without using a separate sensor or measurement device and correcting the settings of the pitching machine based on the result of sensing such that the pitching machine pitches a ball at an accurate speed, and that is capable of analyzing the results periodically sensed by a sensing device and the cumulative results of set ball pitching information of the pitching machine such that the pitching machine automatically performs self-correction, thereby solving a problem in which the set speed of the ball is not accurately realized due to deterioration of the pitching machine over time or due to a change in the weight or the state of the ball, and a baseball practice system using the same.

Abstract: Disclosed are a screen baseball system, in which a pitching machine installed behind a screen pitches a ball toward a batting area through a pitching hole formed in the screen and a user hits the ball in the batting area, configured such that the case in which a virtual pitcher in an image projected on the screen is a left-handed pitcher and the case in which the virtual pitcher is a right-handed pitcher are realized when a ball is pitched through a single pitching hole, whereby the user who hits the ball in the batting area is capable of experiencing the pitch from the left-handed pitcher and the pitch from the right-handed pitcher, and a method of realizing a left-handed pitcher and a right-handed pitcher using the same.

Abstract: A screen baseball system includes: a screen portion arranged in front of a batter's box and having a pitching hole allowing a pitched ball to pass therethrough; a ball pitching device arranged behind the screen portion to pitch a ball toward the batter's box through the pitching hole; and a hole opening/closing device configured to operate to close the pitching hole when the ball pitching device does not pitch the ball and to open the pitching hole when the ball pitching device pitches the ball.

Abstract: Disclosed are an image-processing-type sensing device and sensing method that are capable of acquiring an image of the motion of a pitched ball or a hit ball and analyzing the acquired image in order to calculate an accurate and rapid motion model of the ball, which shows how the ball moves, in a baseball practice apparatus that allows a user to perform a baseball practice or to play a baseball game, whereby it is possible to very accurately and rapidly calculate various kinds of information necessary for conducting the baseball practice or the baseball game, such as motion parameters of the pitched ball or the hit ball, a baseball practice apparatus using the sensing device and the sensing method, and a method of controlling the baseball practice apparatus.

Abstract: A baseball practice apparatus includes: a ball pitching device configured to pitch a ball toward a batting area where a user bats; a detection sensor configure to sense whether the user is located in the batting area; and a control device configured to analyze sensing information of the detection sensor to determine whether the user has prepared for batting in the batting area and cause the ball pitching device to operate according to a preset process when it is determined that the user has prepared for batting.
