Ball-pitching control method of pitching machine in baseball practice system and baseball practice system using the same

A ball-pitching control method of a pitching machine in a baseball practice system comprising a sensing device for sensing a ball pitched toward a batting area by the pitching machine, a pitching angle of the pitching machine being adjustable, the ball-pitching control method comprising:

• calculating and storing a ball motion model using sensing data obtained as a result of the pitching machine pitching the ball at a set pitching angle and the sensing device sensing the pitched ball when a baseball practice or a baseball game is performed;
• calculating a correction factor for correcting a difference between the set pitching angle of the pitching machine and a pitching angle calculated based on the ball motion model using information about the set pitching angle and information about the ball motion model;
• and
• applying the calculated correction factor to the pitching machine such that the pitching machine self-corrects a displacement thereof and pitches the ball when a user takes a baseball practice or plays a baseball game.

A baseball practice system comprising:

• a pitching machine for pitching a ball toward a batting area, in which a user hits the ball, a pitching angle of the pitching machine being adjustable;
• a sensing device for sensing the ball pitched by the pitching machine and generating sensing data;
• and
• a control device for calculating a ball motion model pertaining to the pitched ball using the sensing data received from the sensing device, calculating a compensation factor for compensating for a degree of inclination of the pitching machine using a difference between a set pitching angle at which the pitching machine pitches the ball and the calculated ball motion model, and applying the calculated compensation factor to the pitching machine such that the ball is pitched by the pitching machine in a state in which the degree of inclination of the pitching machine is compensated for when the user takes a baseball practice or plays a baseball game.
