The baseball game system includes a pitching unit for throwing a ball toward a determination region between the inlays; A photographing unit located on a space between the judgment area and the pitching unit; And a swing judging unit for judging whether or not the baseball bat of the user located at the plate is swung based on the image from the photographing unit; The swing determination unit detects a batting position where the batter is located based on the degree of change of the image and determines whether or not the baseball bat swings based on the trajectory of the detected batting and the end of the baseball bat.
Description
BACKGROUND OF THE
In a conventional baseball game system, a baseball bat is photographed at various angles using a plurality of cameras to determine whether or not a baseball bat swings in a determination area.
As such, since the conventional baseball game system requires a plurality of cameras, a large cost is required for system implementation.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a baseball game system capable of accurately determining whether a baseball bat swings with a single camera.
According to another aspect of the present invention, there is provided a baseball game system including: a pitching unit for throwing a ball toward a determination region between ate stones; A photographing unit located in a space between the judgment area and the pitching unit; And a swing judging unit for judging whether or not the baseball bat of the user located at the plate is swung based on the image from the photographing unit; The swing determination unit detects a batting position where the batter is located based on the degree of change of the image and determines whether or not the baseball bat swings based on the trajectory of the detected batting and the end of the baseball bat.
The swing determining section sets a first vector connecting two temporally adjacent ends, sets a second vector perpendicular to the first vector, Determining whether the number of second vectors among the second vectors passing through the detected batting or passing through the detected batting are in a first reference range; It is determined whether the average length of the second vectors is within a second reference range to determine whether the baseball bat swings.
The swing determination unit determines that the number of the second vectors among the second vectors that pass through the detected batter or pass through the detected batter are located in the first reference range and the average length of the second vectors is within the second reference range It is judged that the baseball bat swings when doing.
The swing determination unit further determines whether the sum of the lengths of the first vectors is located in the third reference range.
The swing determination unit determines that the number of second vectors that are directed to the detected batted stones among the second vectors or pass through the detected batts are located in the first reference range, the average length of the second vectors is located in the second reference range, It is determined that the baseball bat swings when the sum of the lengths of the first vectors is within the third reference range.
The baseball bat further includes an indicia pattern.
The marker pattern is located at the end of the baseball bat.
The marking pattern surrounds the end.
The marker pattern has a lighter color than the baseball bat.
And a position detection unit for detecting the position of the hole in the determination region based on the image from the photographing unit.
And a determination unit that determines the ball and strike based on the determination result from the swing determination unit and the detection result from the position detection unit.
The baseball game system according to the present invention provides the following effects.
First, the baseball game system of the present invention can accurately determine whether or not the baseball bat swings in consideration of the batter position, the swing locus and speed of the baseball bat, and the like.
Second, since the baseball game system of the present invention judges whether the swing is a check swing based on the length of the swing trajectory, it is possible to determine the swing more accurately.
Thirdly, the baseball game system of the present invention includes a baseball bat having a display pattern, so that the locus of the baseball bat can be detected more accurately.

Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Thus, in some embodiments, well known process steps, well known device structures, and well-known techniques are not specifically described to avoid an undesirable interpretation of the present invention. Like reference numerals refer to like elements throughout the specification.
The terms spatially relative, "below or beneath", "lower", "above", "upper" and the like, And may be used to easily describe the correlation with other elements or components.
In this specification, when a part is connected to another part, it includes not only a direct connection but also a case where the part is electrically connected with another part in between. Further, when a part includes an element, it does not exclude other elements unless specifically stated to the contrary, it may include other elements.
The terms first, second, third, etc. in this specification may be used to describe various components, but such components are not limited by these terms. The terms are used for the purpose of distinguishing one element from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second or third component, and similarly, the second or third component may be alternately named.
Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.
Hereinafter, a baseball game system according to the present invention will be described in detail with reference to FIGS. 1 to 8. FIG.
