Abstract
A baseball game system is capable of accurately determining a location of a ball using a single camera, the baseball game system including: a pitching unit pitching a ball toward a determination area including a strike zone; a photographing unit positioned in a space between the determination area and the pitching unit; and a location detector detecting a location of a ball based on a plurality of images from the photographing unit. The location detector includes a non-stroke processor detecting a location of a non-struck ball and a stroke processor detecting a location of a struck ball. The non-stroke processor sets first, second, third and fourth straight lines defining the strike zone; calculates, when the ball in the image passes between the first straight line and the second straight line, an average size of the balls between the first straight line and the second straight line; and detects a vertical location of the ball in the determination area based on the average size.
