In some other embodiments, the screen baseball system 100 may optionally further include a strike zone generator (not shown). In some other embodiments, the screen baseball system 100 may optionally further include a groove plate 114 and a pair of batters boxes 116. [ In some other embodiments, the screen baseball system 100 may further optionally include a percussive sound sensing unit 160. [0040] In some other embodiments, the screen baseball system 100 may optionally further include a batting timing detection unit (not shown).

In some other embodiments, the screen baseball system 100 may optionally further include a simulator (not shown) and a starter 180.

The batter is hit by the user 20 at the batter's seat. The stopper 112 may be installed in the batter's seat 110 for the purpose of recovery of the ball 10, facility protection, etc. when the ball 10 discharged from the pitching machine 120 is not struck by the user 20 have. There is no limitation to the material of the stopper film 112, but it may be preferable to use the stopper film 112 as a transparent material in consideration of the operation of the first camera 130, which will be described later. On the other hand, the bottom surface on which the batting seat 110 is placed may be inclined as shown in the example of Fig. 1, so that the ball 10 struck by the user 20 or collided with the stopping membrane 112 may be easily collected .

The pitching machine 120 is disposed at a predetermined distance from the batter 110 and discharges the ball 10 in the direction of the user 20 waiting on the batter 110.

The first camera 130 is disposed opposite to the batting seat 110 and photographs the ball 10 discharged in the direction of the user 20. The ball 20 hit by the user 20 is positioned on the first surface And detects the projected first locus. The figure illustrates by way of example a first camera 130 disposed opposite a pitching machine 120 behind a user 20. As another example, the first camera 130 may be arranged to face the batter 110 in the direction of the pitching machine 120, as shown in the figure.

The second camera 140 is disposed between the batter 110 and the pitching machine 120 and photographs the hole 10 discharged in the direction of the user 20. The second camera 140 photographs the hole 10 hit by the user 20, Detects a second trajectory projected on a second surface intersecting with the first surface.

In one embodiment, the second camera 140 may comprise a plurality of cameras spaced apart from one another. The plurality of cameras may be used as the second camera 140 so that even if the shooting point moves in the course of hitting the ball 10 by the user 20, any one of the cameras can shoot the shooting point, The instantaneous image can be photographed substantially without error.

Further, by using a plurality of cameras as the second camera 140, the ball 10 ejected by the pitching machine 120 is not hit by the user 20 and passes over the groove plate 114, 114 may be photographed by another camera among the plurality of cameras. In this case, the other one of the plurality of cameras may be disposed to face the groove plate 114. [ The control unit 150 analyzes an image photographed by the other camera among the plurality of cameras so that the passing time of the ball 10 passing through the imaginary line extending from the groove plate 114 or the groove plate 114 Can be extracted. The first camera 130 and the second camera 140 may be synchronized with each other so that the control unit 150 controls the movement of the first camera 130 and the second camera 140 at the passage time passing through the imaginary line extending from the groove plate 114 or the groove plate 114 The shot image of the first camera 130 and the second camera 140 synchronized with each other is compared with the strike zone provided by the strike zone generator so that the pitcher machine 120 It can be determined whether or not the ball 10 is a strike or a ball.

Also, by using a plurality of cameras as the second camera 140, even if the ball 10 ejected by the pitching machine 120 is struck by the user 20 and moves at a high speed, the plurality of cameras are synchronized with each other The struck hole 10 can be stably photographed. The images captured by the plurality of cameras synchronized with each other can be utilized for analyzing the speed, direction, etc. of the ball 10 hit by the user 20 by the control unit 150. Accordingly, the screen baseball system 100 disclosed in the present specification can advantageously use the ball 10 stably struck even if a middle-priced high-speed camera is used instead of an expensive high-speed camera, thereby providing advantages in system installation cost and maintenance cost .

On the other hand, the plurality of cameras synchronized with each other can analyze at least one selected from the images taken by the cameras, the rotational direction of the ball 10 hit, the number of rotations per unit time, and combinations thereof. For example, in the case of a baseball ball, a seam is formed during the manufacturing process, and the controller 150 analyzes the motion of the seam on the surface of the hit baseball ball from the image captured by the second camera 140, The rotational direction of the ball 10, and the number of rotations per unit time can be analyzed. The control unit 150 substitutes the Bernoulli principle or Magnus effect for the rotated direction of the impacted hole 10 and the unit time per revolution to determine the accuracy of the hit ball 10 The movement pattern can be analyzed. The Magnus effect is a phenomenon in which an object swirls from a higher pressure side to a lower pressure side as it passes through a fluid (gas or liquid) while rotating. This is because, when the ball 10 is rotated, the pressure of the air varies according to the traveling direction and the rotating direction of the ball, so that the ball 10 moved from the higher side to the lower side of the air moves do. That is, the screen baseball system 100 disclosed herein detects an image of the shot ball 10 using the second camera 140, and from the sensed image, the control unit 150 controls the shot ball 10, The number of revolutions per unit time, and combinations thereof, and can be applied to the Bernoulli principle or the Magnus effect, so that the ball 20 can be struck by the user 20 while being struck by the user 20 It is possible to analyze the movement pattern of the hit ball 10 according to the applied rotational force. It is needless to say that the image captured by the first camera 130 can be used in this process.

The control unit 150 controls the traveling speed and the traveling direction of the ball 10 struck by the user 20 from the first trajectory and the second trajectory sensed by the first camera 130 and the second camera 140, .

Meanwhile, a pair of batters box 116 disposed adjacent to the groove plate 114 and the groove plate 114 may be disposed in the batten 110. The pair of batter bins 116 is a virtual or actual one extending from the pair of batter bins 116 by a predetermined length in the first base and third base directions, respectively, as shown in the example of Fig. And can be connected to the ruby base line 117 and the third base line 118. The control unit 150 analyzes the progress speed and direction of the hit ball 10 and analyzes whether the hit ball 10 is out of the first base line 117 or the third base line 118 It is possible to judge whether or not it is a foul.

In addition, the hit sound sensing unit 160 is disposed adjacent to the batting seat 110 and can sense a hit sound generated when the user 20 hits the hole 10 discharged from the pitching machine 120 . The sensed sound may be provided to the controller 150. In this case, the control unit 150 can determine the analysis time of the first trajectory and the second trajectory based on the hit sound detected from the hit sound sensing unit 160. Accordingly, the screen baseball system 100 disclosed in the present specification can determine the time of detecting the sound of the hit in the process of calculating the progress speed and the progress direction of the hit ball, thereby reducing the number of frames of the analysis target image, It is possible to reduce the load of the arithmetic processing.

The batting time detection unit (not shown) is disposed in the bat 30 used by the user 20 and is generated when the user 20 hits the ball 10 discharged from the pitching machine 120 The speed of the bat 30 can be detected. The speed change of the detected bat 30 may be provided to the control unit 150. [ In this case, the control unit 150 may determine the analysis time of the first trajectory and the second trajectory based on the signal detected from the hit timing detection unit. The hit timing detecting unit may include at least one selected from an acceleration sensor for measuring an acceleration in accordance with the velocity change of the bat 30, an impact sensor for measuring an impact amount according to the velocity change of the bat 30, . The acceleration sensor may be disposed adjacent to the handle of the bat 30 and the controller 150 may analyze the striking pattern of the user 20 using the bat 30 from the acceleration measured by the acceleration sensor . The acceleration sensor disclosed in the present specification not only measures acceleration in at least one direction selected from the x-axis, the y-axis, the z-axis, and a combination thereof, but also measures the acceleration in at least one direction selected from the x-, y-, It is used as a generic term to refer to a sensor that measures rotational acceleration based on an axis.

More specifically, the impact sensor may sense the amount of impact applied to the bat 30 during the batting process of the user 20. The amount of the impact may be detected in the form of a pressure change, for example, in which case a pressure sensor may be used as the impact detection sensor. The acceleration sensor can measure acceleration, which is a rate of change per hour of the speed and speed of the bat 30, which is changed during the batting process of the user 20. The acceleration sensor can sense a change in the velocity of the bat 30 and a corresponding change in acceleration as the bat 30 hits the ball 10. Generally, in the batting process, the user 20 rotates the bat 30 with the knob portion of the bat 30 as a rotation axis. Accordingly, when the acceleration sensor is disposed at the knob portion of the bat 30, the acceleration (for example, rotation) during the process of rotating the bat 30 for batting based on the time when the user 20 is preparing for batting Acceleration) can be measured. The control unit 150 may analyze the hit pattern of the user 20 using the bat 30 by combining the physical information of the bat 30 such as the measured rotational acceleration and the length and the volume. The batting pattern analysis of the user 20 by the control unit 150 may be analyzed in combination with the images captured by the first camera 130 and the second camera 140. [ Accordingly, the screen baseball system 100 disclosed in the present specification can determine the speed change point in the process of calculating the progress speed and the progress direction of the hit ball, thereby reducing the number of frames of the analysis target image, It is possible to reduce the load of the arithmetic processing. In addition, it is possible to provide a function by which the user 20 can effectively train by analyzing and providing the batting pattern of the user 20. [

The process of calculating the traveling speed and the traveling direction of the ball 10 struck by the user 20 by the control unit 150 will be described later with reference to FIG. 4 to FIG.

A strike zone generating unit (not shown) is disposed to face the batter stones 110 and detects the physique information of the user 20 that is waiting on the batter plate 110 and the groove plate 114 disposed on the batter stones 110, Create a zone. The strike zone is generally defined as the lower limit of the horizontal line of the lower portion of the batter's knee and the horizontal line midway between the line of the uniform pants belt and the shoulder of the batter 20, which is a virtual space on the groove plate 114 . The strike zone generator may generate the strike zone through the physique information of the user 20 obtained by analyzing the image of the user 20 waiting in the batting table 110 or may generate the strike zone through a sensor Can be generated.

In the former case, the strike zone can be generated by capturing the motion of the user 20 and analyzing the physique information of the user 20 therefrom. In this case, a separate camera may be used to acquire an image of the user 20, but an image captured by the first camera 130 may be utilized.

In the latter case, the operation of the user 20 can be recognized by utilizing a Kinect sensor as an example of the sensor. The Kinect sensor is a device that emits infrared rays of a pixel unit to an object on the front face, that is, a user 20, by using an infrared projector, receives infrared rays reflected from the user 20, and recognizes the physique information of the user 20 It says. In order to more accurately recognize the physique information of the user 20, the Kinect sensor may include a database storing position data of the main skeleton constituting the human body. That is, the Kinect sensor can easily obtain the information of the body part corresponding to the skeleton of the user 20 by utilizing the skeleton information of the human body stored in the infrared projector and the database. Through this, the physique information of the user 20 can be obtained, and the strike zone generator can generate the strike zone by analyzing the physique information. In this case, the strike zone generating unit may generate the strike zone using the information provided from the sensor, which is directly attached to the human body of the user 20 ), And generate the strike zone therefrom.

The screen 170 may be disposed opposite the batter 110. The pitching machine 120 may be disposed in front of the screen 170 but may be disposed behind the screen 170 for convenience of the user 20. That is, the screen 170 may be disposed between the pitching machine 120 and the batter 110.

Of course, as noted above, the first camera 130 may be positioned to face the batting 110 in the direction of the pitching machine 120. [

5, the first side 132 is a plane perpendicular to the plane including the battalion 110 on which the user 20 is seated, and the second side 142 is a plane perpendicular to the plane, Or may be a plane that is parallel to the plane including the batter 110. [ 5 shows a plane 142b including a batting surface 110 as a second surface 142, a plane 142a including a strike 10 parallel to a plane 142b including the batting 110 Is shown as an example. The distance between the plane 142a and the plane 142b corresponds to the height at the point of impact of the hit ball 10 with respect to the ground. The control unit 150 can calculate the distance of the hit ball 10 more accurately when considering the height along with the traveling speed and the traveling direction of the hit ball 10 calculated by the controller 150. [

The control unit 150 measures a first angle 1 from the first trajectory 134 to the struck hole 10 with the second surface 142 and measures the struck hole 10 from the second trajectory 144, The horizontal angle &thetas; formed with the reference line set on the second surface 142 can be measured. The reference line may be a first base line 117 corresponding to the x axis of the figure, a third base line 118 corresponding to the y axis of the figure, or a groove plate 114) and a line connecting the center of a second base (not shown) or a pitcher mound (not shown). Alternatively, the baseline may pass through the center of the plate 114 and may comprise an imaginary line bisecting the angle formed by the first base line 117 and the third base line 118. In the figure, a first base line 117 is used as the reference line as an example. The control unit 150 analyzes the selected trajectory 134, the second trajectory 144 and a combination thereof to analyze the progress speed of the hit ball 10, And analyze the traveling direction of the hit ball 10 from the first angle? 1 and the horizontal angle?.

More specifically, the control unit 150 receives images of the shot ball 10 photographed by the first camera 130 and the second camera 140, which are synchronized with each other and shot at high speed or super high speed. The velocity of the ball 10 in the y and z directions is calculated from the plurality of images supplied from the first camera 130 and the velocity of the hit ball 10 is calculated from the plurality of images provided from the second camera 140, The velocity in the x direction and the y direction, respectively. The control unit 150 can calculate the velocity of the hit ball 10.

Meanwhile, the controller 150 analyzes the horizontal angle of the hit ball 10 corresponding to the reference line from the horizontal angle &thetas; measured from the image provided by the first camera 130 and the second camera 140 The first angle? 1 and the horizontal angle? Can be transformed through a generally used coordinate transformation method to analyze the rising angle, that is, the vertical angle of the hit ball 10. The control unit 150 can analyze the traveling speed of the ball 10 and the traveling direction.

The screen baseball system 100 disclosed herein may include a groove plate 114 disposed in the batter's seat 110 and a pair of batter's box 116 disposed adjacent the groove plate 114. [ have. The pair of batter bins 116 includes virtual or actual first base lines 117 extending from the pair of batter bins 116 by a predetermined length in the first base and third base directions, Line 118. < / RTI > In this case, the controller 150 determines whether the ball 10 struck from the horizontal angle? Is out of the first base line 117 or the third base line 118, and then determines whether or not the ball is a foul .

6, the first side 132 is a plane perpendicular to the plane including the batting seat 110 to which the user 20 is seated and the second side 142 is a plane perpendicular to the plane, Or may be a plane that is parallel to the plane including the batter 110. [ 6 (b), the control unit 150 controls the vertical movement locus 136 in which the hole 10 struck from the first locus 134 moves perpendicular to the second surface 142 And the horizontal trajectory 144 (the second trajectory 144), in which the hole 10 struck from the second trajectory 144 moves on the second surface 142, as shown in Fig. 6 (c) ) Can be extracted. The control unit 150 analyzes the rate of change of the vertical movement locus 136 and the horizontal movement locus 144 from the extracted vertical movement locus 136 and the horizontal locus locus 144, Can be analyzed. The control unit 150 determines whether the hitting ball 10 moves in the three-dimensional space from the extracted vertical movement locus 136 and the horizontal movement locus 144, as shown in FIG. 6 (d) 10 can be calculated. In this case, the control unit 150 passes the point at which the vertical movement locus 136 and the horizontal locus locus 144 meet, or the locus where the extension line of the vertical locus locus 136 meets the extension line of the horizontal locus locus 144, From the angle? Between the virtual line perpendicular to the two sides 142 (having the same direction as the normal vector of the second surface 142) and the movement path 12 of the struck hole 10, (90 ° -?) Formed between the first surface (10) and the second surface (142) to analyze the traveling direction of the shot hole (10). In Fig. 6, the z-axis is shown as an imaginary line as an example.

In this case, when the photographing position of the first camera 130 is located close to the hit point, the first locus 134 sensed and sensed by the first camera 130 is a change in the position of the first camera 130 Can be distorted. Therefore, the photographing position of the first camera 130 needs to be located a sufficient distance from the shooting position. The sufficient distance is set to a degree that the point light source is recognized as a planar light source within an error range when the light provided by the point light source reaches the shot hole 10, assuming that the point light source is located where the first camera 130 is located Distance is enough. This is because the vertical movement trajectory 136 extracted from the first trajectory 134 even if the photographing position of the first camera 130 changes when photographing through the first camera 130 at a sufficient distance from the impact point It is not affected. If it is difficult to secure the sufficient distance of the first camera 130, a plurality of cameras (not shown) synchronized with each other as the first camera 130 may be used to capture an image photographed from the plurality of first cameras It is possible to correct the vertical motion locus 136 through the control unit 150 to extract the vertical motion locus 136 with high accuracy.

The second camera 140 may include a plurality of cameras disposed to be spaced apart from each other so that even if the shooting point moves during the hitting of the ball 10 by the user 20, And a point photographing camera may be located on the path of the imaginary line passing through the hit point. In Fig. 6, the z-axis is shown as an imaginary line as an example. The batting point photographing camera may sense the second trajectory 144 of the ball 10 from the hit point. The control unit 150 extracts the vertical movement locus 136 of the struck hole 10 from the first trajectory 134 based on the striking point and determines whether the struck hole 10 from the second locus 144 The horizontal movement locus 144 moving on the second surface 142 can be extracted. The control unit 150 calculates the movement path 12 of the hit ball 10 from the vertical movement trajectory 136 and the horizontal movement trajectory 144 extracted based on the hit point in the manner described above, The traveling speed and the traveling direction of the hole 10 can be analyzed. The detection of the hit point and the second trajectory 144 can be performed through the shooting point photographing camera to more accurately analyze the traveling speed and the traveling direction of the hit ball 10. [

The remaining cameras of the plurality of cameras other than the hit point photographing camera may be synchronized with the hit point photographing camera to measure the second trajectory 144. [ Accordingly, even if the second camera 140 uses a high-speed camera at a low price rather than an expensive high-speed camera, the ball 10 stably hit can be used, which is advantageous in terms of system installation cost and maintenance cost.

The controller 150 may analyze the horizontal angle θ formed by the hit ball 10 with the reference line set on the second surface 142 from the horizontal movement trajectory 144. The reference line may be a first base line 117 corresponding to the x axis of the figure, a third base line 118 corresponding to the y axis of the figure, or a groove plate 114) and a line connecting the center of a second base (not shown) or a pitcher mound (not shown). Alternatively, the baseline may pass through the center of the plate 114 and may comprise an imaginary line bisecting the angle formed by the first base line 117 and the third base line 118. In the figure, a first base line 117 is used as the reference line as an example. The control unit 150 analyzes the selected trajectory 134, the second trajectory 144 and a combination thereof to analyze the progress speed of the hit ball 10, The direction of the impacted hole 10 can be analyzed from the vertical angle (90 DEG -φ) and the horizontal angle degree (?).

The screen baseball system 100 disclosed herein may include a groove plate 114 disposed in the batter's seat 110 and a pair of batter's box 116 disposed adjacent the groove plate 114 . The pair of batter bins 116 includes virtual or actual first base lines 117 extending from the pair of batter bins 116 by a predetermined length in the first base and third base directions, Line 118. < / RTI > In this case, the controller 150 determines whether the ball 10 struck from the horizontal angle? Is out of the first base line 117 or the third base line 118, and then determines whether or not the ball is a foul .

More specifically, the control unit 150 receives images of the first camera 130, which is synchronized with the first camera 130 at high speed or super high speed, and the shot ball 10 photographed by the shooting point shooting camera. The velocity of the ball 10 in the y and z directions is calculated from the plurality of images provided from the first camera 130 and the velocity of the ball 10 captured from the plurality of images provided from the shooting point camera is calculated The velocity in the x and y directions can be calculated. The control unit 150 can calculate the velocity of the hit ball 10.

6 (b), the control unit 150 determines whether or not the first trajectory 134 from the first surface 132 of the struck hole 10 provided by the first camera 130 The vertical movement locus 136 is measured. The control unit 150 moves the horizontal movement locus 144 from the second locus 144 on the second surface 142 of the struck hole 10 provided by the hit point photographing camera, That is, the distance that the struck hole 10 moves in a direction parallel to the second surface 142. [ In this case, the vertical movement locus 136 and the horizontal movement locus 144 respectively indicate the distance that the struck hole 10 has risen vertically during a predetermined period of time (for example, corresponding to the photographing time interval of the camera) It can correspond to a distance. 6 (d), the controller 150 can calculate the vertical angle (90 ° -?). The control unit 150 may calculate the horizontal angle &thetas; of the hit ball 10 corresponding to the reference line from the image provided by the hit point photographing camera. Through the above-described process, the controller 150 can calculate the progressing speed of the hit ball 10, the horizontal angle degree? And the vertical angle 90 ° -φ formed with the reference line, 10) can be calculated.

As described above, the screen baseball system 100 disclosed in the present specification uses the second camera 140 or the first camera 130 and the second camera 140 to capture the image of the hit ball 10 And the controller 150 can analyze at least one selected from the rotation direction of the shot 10, the number of revolutions per unit time, and a combination thereof, and outputs the result to the Bernoulli principle or the Magnus effect It is possible to analyze the movement pattern of the hit ball 10 according to the rotational force applied to the hit ball 10 in the process of being struck by the user 20. This makes it possible to more accurately calculate the traveling speed and traveling direction of the hit ball 10. [

Hereinafter, the calculation process of the velocity and the vertical angle (90 DEG -φ) of the hit ball 10 will be described as an example. 6, when the hit point is the origin, the ball 10 struck by the user 20 passes through a space corresponding to the coordinates of (x1, y1, z1) at time t1, (x2, y2, z2) at the time t2 > t1). coordinate values of x1 and y1 can be extracted from the image captured by the second camera 140 or the shooting point camera at time t1 and the coordinate values of z1 can be obtained from the image captured by the first camera 130 at time t1 Can be extracted. Further, the coordinate values of x2 and y2 can be extracted from the image captured by the second camera 140 or the shooting point camera at time t2, and the coordinate value of z2 can be extracted from the image captured by the first camera 130 at time t2 Can be extracted from the image. Through this process, it is possible to extract coordinate values for the movement path 12 of the hit ball 10 according to the time change in the three-dimensional space having the hit point as the origin.
