Fig. 1 shows a perspective view of a pitch practice device 100 according to a preferred embodiment of the present invention. Fig. 2 shows a plan layout of the pitch practice apparatus 100 of Fig. 1 and an overall configuration of an online game system.

FIG. 1 shows the configuration of one line of the practice apparatus 100, and it is possible to install such a plurality of line exercising apparatuses 100 in a store having an appropriate width. One line of practice implement 100 includes a socket box 16 and a pitcher plate 24 as a structure and a bottom surface 28 connecting the socket box and the pitcher plate and a support structure 22 raised from the edge of the bottom surface, .

The bottom surface 28 is designed to be inclined such that the baseball ball thrown toward the pitcher jacket box 16 falls and is automatically recovered to the baseball collecting cylinder 18 near the pitcher plate 24. A wire mesh or the like is installed in the support structure 22 so that the baseball ball does not deviate outwardly.

A plurality of cameras 10, 12, and 13 for photographing the pitching form of the pitching practitioner and the motion trajectory of the baseball ball are also installed in the pitching practice apparatus 100. A first camera 10 for capturing the vertical movement of the baseball is provided at the rear side of the pitcher plate 24 and a second camera 10 is provided at the upper portion of the support structure 22 at a proper point between the pitcher plate 24 and the socket box 16 A second camera 12 for capturing the horizontal movement of the baseball and a third camera 13 for capturing the pitching form of the pitching practitioner are installed in front of the side of the pitcher 24. Of course, the first camera may be installed in the vicinity of the socket box 16, and the installation positions of the second camera 12 and the third camera 13 may also be installed in other places than the illustrated positions. The cameras 10, 12, and 13 are connected to the store computer 200 and provide moving images to the store computer 200.

Between the second camera 12 and the pitcher plate 24, first sensors 14a and 14b for detecting the passage of the baseball ball are installed. The first sensor includes a plurality of infrared ray detection sensors such that a plurality of light emitting elements 14a and a plurality of light receiving elements 14b face each other and an arrangement interval of each of the light emitting elements 14a and the light receiving elements 14b, So that the baseball ball passes through the optical path between at least a pair of light emitting elements and the light receiving element so that the passing of the baseball can be detected. The light receiving element 14b is connected to the store computer 200 and provides the first detection signal S1 when the passage of the baseball ball is detected.

In addition, the pitch practice device 100 is connected to the store computer 200. When the coin is inserted, the pitch practicing apparatus 100 recognizes the coin input, turns on the power, initializes the system to make it operable, and outputs the pitching result and the remaining pitching times And a control box (20). The control box 20 includes a display panel that displays various pitch recordings such as a ball speed, a score, a bonus, the number of pitches, etc., and buttons for selecting various game menus. In addition, a sound recorded in a digital manner by incorporating a voice processing means (not shown) is recorded in advance, and a speaker (not shown) is informed of various decisions related to the determination or score of the strike / Lt; / RTI >

3A is a cross-sectional view showing the configuration of the socket box 16 of the pitch practice device 100. The configuration of the socket box 16 will be described in detail. The socket box 16 is manufactured in the form of a rectangular box having a predetermined size, width x width x thickness of 1500 mm x 1800 mm x 110 mm. The front plate of the socket box 16 is made of an elastic cover (for example, a conveyor belt plate) in which only a portion corresponding to the strike zone is perforated so that the baseball ball can pass through, In order to enhance the sense of realism, the batting figure of the actual batter is added and closed. The width and length of the strike zone are set to, for example, about 43.2 cm x 60 cm. Second sensors 32a to 32d for detecting where the baseball hole 23 has passed through the strike zone are disposed inside the socket box 16 and at the rear of the baseball hole when the baseball hole has passed through the strike zone, A protective curtain (34) is disposed to absorb the impact force of the baseball hitting against the baseball, and a scoring plate (36) is also provided at the rear of the protective curtain (34). In addition, on one side of the protective curtain 34 is attached a vibration sensor 38 which detects the arrival of the ball in response to the impact force transmitted when the ball hits and provides the third detection signal S3 to the store computer.

The protective curtain 34 is made of a synthetic resin material which is transparent and has excellent strength and flexibility so that the score plate 36 can be seen when viewed from the pitcher plate 24, and only the upper portion is fixed so that the impact ball is absorbed, It is preferable to install it in a curtain shape.

The score board 36 divides the strike zone into, for example, nine small regions, places a score sign giving a score for each small region, places a backlight lamp for each score, and illuminates only a lamp of a specific small region in response to a predetermined score display signal So that the score is displayed.

A plurality of second sensors 32a to 32d are installed to surround the score plate 36 as shown in FIG. 3B in order to detect which area of the strike zone the throwing ball has passed. As the second sensor, it is preferable to use an infrared sensor. The plurality of light emitting elements 36a and 36c and the plurality of light receiving elements 36b and 36d are arranged to face each other and the arrangement interval of the light emitting elements 36a and 36c and the light receiving elements 36b and 36d is larger than the diameter of the baseball hole So that the baseball ball can pass through at least the light path between the light emitting element and the light receiving element of at least the horizontal axis and the vertical axis so that the passing point of the baseball ball can be detected. For example, in FIG. 3B, when the baseball ball passes through the fourth course of the score plate, any one of the middle light receiving elements VS2 'of the light receiving elements 32b on the side and the left light receiving element HS1' Generates a second detection signal and provides the second detection signal to the store computer 200, respectively. Then, the store computer 200 determines which spot of the strike zone the baseball has passed through by determining the point at which the second detection signal is generated from the light receiving element. The light receiving elements 36b and 36d are connected to the store computer 200 to provide a second detection signal S2 when the passage of the baseball is detected.

A computer 200 is installed in each store of the baseball training center, and the computer receives detection signals transmitted from the first, second, and third sensors installed on the pitch line and moving images provided from the cameras 10, 12, and 13 And performs necessary calculations, graphically processes the moving picture data, and provides the result of the pitching to the control box 20 so that the pitching practitioner can know the result of the pitching of the pitcher, or through the Internet 250, And / or graphic data to the game server system 300. When a moving picture is transmitted to the game server system 300, the moving picture file is compressed and transmitted.

FIG. 6 is a flowchart for explaining the function of the store computer. FIG. 7 is a flowchart for explaining a procedure of processing the movement of the baseball ball by the store computer as graphic data. Referring to these figures, The function will be described in more detail.

When the pitching practitioner inserts a coin into the control box 20 (step S10), the control box 20 recognizes it, puts power on each component of the pitching practice apparatus, initializes the system, (Step S12).

The first sensors 14a and 14b and the second sensors 32a to 32d and the third sensor 38 are controlled by the first detection signal S1 and the second detection signal S1, respectively, (S2) and a third detection signal S3 (S16), and performs various calculations using the received various detection signals (S18).

First, the store computer 200 calculates the speed of the baseball. Dependent view of a football is a second sensor (32a ~ 32d) and the third second detection signal (S2) and the third sensor, which is a distance L ₂ between the sensors 38, the second sensor (32a ~ 32d) output ( And the third detection signal S3 output by the first to third detection units 38 and 38 is divided by the received time difference. The intermediate speed of the baseball is determined by a distance L ₁ between the first sensors 14a and 14b and the second sensors 32a to 32d with a first detection signal S1 output by the first sensors 14a and 14b And the second detection signal S2 output by the second sensors 32a to 32d is divided by the received time difference.

Next, ball / strike, score determination, and pitching count are performed. The store computer 200 receives the first detection signal S1 from the first sensors 14a and 14b for a predetermined period of time, that is, when the baseball ball passes through the first sensors 14a and 14b and the second sensors 32a to 32d, If the second detection signal S2 of the second sensors 32a to 32d is not received within the time (hereinafter referred to as "maximum passage time") required to pass the separation distance L ₁ between the _first and second sensors 32a to 32d at the slowest speed, It is judged to be "ball". If the second detection signal S2 is received within the predetermined time, it is determined as 'strike' in this case. In addition, it is determined which position of the light receiving element the second detection signal S2 has generated to determine how many points the baseball hole has passed through the strike zone. Then, the number of pitches is counted by using the first detection signal S1 generated every time the baseball passes the first sensor 14a or 14b.

Information such as the speed of the baseball ball calculated, the determination of the strike / ball and the score determination, the number of times of pitching, and the like are stored in the storage device in the store computer 200 and transmitted to the control box 20, And the judgment result is outputted realistically through the speaker. In addition, the store computer 200 turns on the backlight lamp of the score plate 36 to display the determined score (step S20).

On the other hand, the store computer 200 determines whether the first detection signal S1 is inputted from the first sensor 14a or 14b and the motion trajectory of the baseball ball taken by the cameras 10, 12, The moving picture is received and stored in a storage means (not shown) (Step S22). Reception of the moving picture is performed only during a short time of the time taken for the second detection signal S2 to be inputted from the second sensors 32a to 32d or the maximum passage time to prevent unnecessary moving picture storage. Particularly, in the case of a moving image relating to a motion trajectory of a baseball, a predetermined graphic processing is performed to process the moving ball of the baseball into graphic data that can be viewed in various ways three-dimensionally at a desired angle (step S24).

A method of representing the motion trajectory of a baseball ball with three-dimensional graphic data will be described with reference to Figs. 4, 5, and 7. Fig.

Assuming that the pitching speed is, for example, about 145 [Km / h], the moving distance per second of the ball is about 145,000/3600 = 40.27 [m / sec]. Therefore, assuming that the moving distance per second of the baseball ball is 40 [m], in order to practically analyze the pitch, the frame rate is higher than that of a general TV camera having a frame rate of about 30 frames per second, It is necessary to photograph the motion trajectory of the baseball ball with a special camera that can be controlled. If the camera can take a picture in a high-speed electronic shutter mode with a range of about 5 [m] wide and 1/1000 second, the amount of motion of the ball in one frame is about 40 [m] / 1000 = 4 [ , It is possible to obtain an image at a level at which the motion locus and the analysis of the pitch can be accurately performed. Assuming that the frame rate is 150 [frames / second], an image can be acquired at an interval of about 26 [cm] (= 40 m / 150 frames).

The store computer 200 receives the first detection signal S1 provided by the first sensors 14a and 14b when the pitcher throws the ball through the first sensors 14a and 14b in operation S30, And the second camera 10, 12 (step S32). The first camera 10 and the second camera 12 are activated simultaneously from the time when the thrown ball passes through the first sensor 14a and 14b so that a continuous image of a frame unit as shown in FIG. / RTI > That is, the exposure time (high-speed shutter operation time) unit _{(t 0, t 1, t} 2, t 3) image f (n-1) of an optical image frame-by-frame screen of a, f (n), f (n + 1 ), and f (n + 2), and appears as a moving form of frame interval time unit according to the frame progression. Accordingly, it is possible to detect a three-dimensional movement path of the baseball ball by obtaining a motion vector of a screen between frames using the obtained image (Step S34).

Motion vectors can be transformed into three-dimensional graphic data that can be observed in various ways from a desired angle three-dimensionally by processing the motion path of the baseball ball with vector graphics software that has been already commercialized (S36 step). A natural image is an image represented by pixels, which is called a bitmap image or a raster image. On the other hand, geometric shapes such as line segments, rectangles, and circles can be represented by starting points, end points, centers, and radii Such a geometric representation is called a vector graphic. Vector graphics require time to draw a circle or a straight line, but since it is possible to move the vertex, change the radius of the circle, and move the center, it is possible to edit and view the trajectory of the ball It is preferable to perform vector graphics processing for pitch analysis such as pitch analysis or pitch angle analysis. Such a vector graphic processing may be performed directly by the store computer 200, but it may also be a method of receiving the moving image from the store computer 200 and performing vector graphic processing by the game server system 300.

A method of obtaining a motion vector in each frame image is as follows. First, the current frame f (n) is moved by the small distance (dx _k , dy _k ) and the sum D _k of deviations of pixel data with f (n-1) is calculated.

_{Here, f n (x i, y} i) is the pixel data of the current _{frame, f n-1 (x i} + dx k, y i + dx k) is the pixel data of the previous frame. The movement distance (dx _k , dy _k ) when the value of the sum (D _k ) of the calculated deviations is minimum is determined as a motion vector to be sought. Since only the baseball ball moves on one screen, if the position P2 of the baseball ball is exactly overlapped with the baseball ball position P1 of the previous frame by moving the current frame, pixel data between the current frame and the previous frame at this time Lt; / RTI > will be minimized. Therefore, since the amount of vector in which the current frame moves at that time is equivalent to the amount of motion vector of the baseball, it is generally applied to a plurality of frames to obtain an interframe motion vector between the current frame and the previous frame, The vector can be treated as a motion vector of a baseball ball. The motion vector thus obtained is temporarily stored in the store computer 200.

After the data processing as described above, it is checked whether the predetermined number of remaining helmets remains. If the remaining helmets remain, pitching is repeated again and steps S16 to S20 are repeated (step S26). If the number of remaining pitches is not remaining, the average restraint, the maximum restraint, the total number of the obtained points and the average score are calculated and provided to the control box 20 as a final pitching result of the pitching game to be displayed and the end of the game Step S28).

Next, FIG. 8 shows a configuration of an offline / online baseball game system in which a pitch practice device installed in each store is linked to a game server system via the Internet.

The store computers 200-1 and 200-2 installed in the pitching practice fields of the respective merchants are connected to the game server system 300 via the Internet 250. The game server system 300 includes a game server 310, The web server 320 is connected to the LAN, and various data and information are provided in response to various service requests of the client computer 400. In addition, the game server 310 manages the database 330.

The database 330 stores a moving picture file (three-dimensional vector graphic data, if vector graphics processing is directly performed in each store computer) transmitted from each of the store computers 200-1 and 200-2 and a personalized helmet And stores the record data in the moving image database and the recording database, respectively.

The game server 310 analyzes the pitch record data of each pitcher stored in the database 330 and calculates the nationwide ranking related to the pitching speed and / or the pitching score and stores it in the ranking database. Also, the member database is managed by receiving the member information through the web server 320.

The web server 320 processes the membership subscription procedure for the various client computers 400 connected via the Internet 250, and transmits a video related to the pitch record data, ranking data or pitch appearance in response to a request from the client computer, Graphic data and the like from the game server 310 and performs functions such as managing members' private rooms.

The game server 310 also has a function of playing an offline-online interactive baseball game. The game should be off-line, that is, the actual pitcher in the pitching practice must avoid it if the online batter chooses one of his / her computer's 9-point scoreboards for the strike zone. The game server system compares the strike zone passing position information of the pitches of the ball received from the store computer 200, that is, the number information of the scoreboard with the scoreboard number received from the batter's computer 400, And provides the result to the client computer 400 and the store computer 200 via the web server 320. [ At this time, the strikeout system is applied. Furthermore, it allows players to play the game in such a way that the virtual batters on-line put the actual pitches of the actual off-line pitchers instantly in the course. In addition to this one-on-one game, it also has a team-based game function that allows a team to compete by tying the nation's virtual batters into one team.

In such a baseball game, a company operating a game server system organizes a baseball game event, reserves a game application for a player who plays a pitcher role and a batter player, sets a competition date, Place it on a computer and play the game in real time.

Thus, the present invention can plan various interesting baseball games by utilizing various pitch record data obtained from actual pitches. For example, a player who has the highest number of strikes (aka Kim Byung-Hyun) and a player who scored the score of the strike zone score the highest score, (Aka score game), a game in which a high man wins (a speed + score game) by comparing the sum of the sum of the redemption and the acquired score after throwing the last ball, And a game (a couple of games) in which the winning combination is determined by comparing the sum of the speed and the acquired score. These games may be performed individually in each pitching practice field, or may be conducted online in connection with the game server system 300. [
