Hereinafter, a method for modeling a pitch trajectory image at the time of a batter and a server 200 for operating the method will be described with reference to the accompanying drawings.

1 is a schematic diagram of a pitcher trajectory imaging system 10 in accordance with various embodiments of the present invention.

The pitcher trajectory image system 10 may include at least one camera apparatus 100_1 to 100_N and a server 200. [ 1, the camera device 100 and the server 200 are shown as independent components, but the present invention is not limited thereto. As a non-limiting example, the pitcher trajectory imaging system 10 may be configured as a module or system of the camera device 100 and the server 200. In this case, the camera device 100 and the server 200 can transmit / receive data mutually by an internal signal transmission system that is electrically configured.

The camera apparatus 100 may perform a function of shooting or imaging an object in a real world three-dimensional space and projecting the object in a two-dimensional plane. As such a camera apparatus 100 in the embodiment of the present invention, for example, a high-speed camera may be used. According to various embodiments, the camera device 100 may include, but is not limited to, an optical portion, an image sensor, and a signal processing portion.

The optical unit may be driven by a mecha-shutter, a motor, and an actuator, and the actuator may perform operations such as zooming and focusing. Such an optical unit can capture or photograph an image of a surrounding area.

The image sensor can detect an image captured or photographed by the optical unit and convert it into an electrical signal. Such an image sensor may include a CMOS or CCD sensor.

The image processing unit buffers the frame images output from the camera device, and scales the frame image output from the camera device to a display image size in the preview mode.

In addition, the camera device 100 may include a communication module capable of transmitting the collected image or image to the server 200. [ The communication module may be implemented by a wired communication (e.g., a terminal or a connector) or a wireless communication (e.g., Bluetooth, WIFI, etc.). In addition, the camera device 100 may transmit and receive data to / from the server 200 using a network.

Further, in order to acquire three-dimensional information (e.g., three-dimensional image) according to various embodiments of the present invention, the plurality of camera apparatuses 100 may use hardware / software of the same kind and specification, but is not limited thereto.

The server 200 electrically connects or communicates with at least one camera device 100 to receive an image or an image from the camera device 100 and generate 3D pitch image based on the received information, An electronic device or a program that performs and processes functions. The specific configuration of the server 200 will be described later in detail with reference to FIG.

2 is a block diagram of a server 200 according to various embodiments of the present invention.

According to various embodiments, the server 200 includes a communication unit 210, a control unit 220, a 3D pitching image generating unit 221, a interval setting unit 223, a 3D pitching image processing unit 225, 227, and a storage unit 230. As a non-limiting embodiment, the server 200 may omit at least some of the components of FIG. 2 or may further comprise additional components.

The communication unit 210 may connect the communication between the camera device 100 and the server 200. [ For example, the communication unit 210 may be connected to the network 300 through wireless communication or wired communication, and may receive image information including dynamic objects (e.g., pitching exercises or balls used in games) from the camera apparatus 100 Lt; / RTI > As a non-limiting example, when the server 200 and the camera apparatus 100 are configured as a single module, the communication unit 210 may be implemented with a circuit (e.g., a bus) that communicates communication among the components.

The communication unit 210 may transmit the 3D helmet image generated, processed and transformed by the server 200 to an external device such as a broadcast relay server under the control of the control unit 220. [

The control unit 220 may perform a data processing function for controlling the signal flow between the overall operation such as the power supply control of the server 200 and the internal configuration of the server 200 and for processing the data. The control unit 220 may include at least one processor and may be a central processing unit (CPU), an application processor (AP), or a communication processor (CP) ≪ / RTI >

The 3D helmet image generating unit 221 can receive the image information photographed at the helmet scene from at least one camera apparatus 100 and can generate the 3D helmet image based on the received image information.

Here, the image information may be a still image (for example, an image) or a moving image captured or photographed by the camera apparatus 100, and the image information may include movement of a ball thrown by a pitcher in a field such as a pitching practice .

In addition, the 3D pitching image may be 3D image content generated by the 3D pitching image generating unit 221 based on the image information. According to various embodiments, the 3D helper image may include a ball object and a background object. The ball object may be, for example, a video object or an image of a ball (e.g., a baseball) included in the 3D helmet image, and the background object may be a video object or image except a blank object in the 3D helmet image.

In the process of generating a 3D helmet image, a ball thrown by a pitcher may be used as a dynamic object in setting a camera parameter (e.g., distance information between cameras), but is not limited thereto. The 3D helmet image generating unit 221 may generate the 3D helper image using the image information received from each camera device 100, the pattern of the helmet field, and a known three-dimensional image conversion formula.

For example, in a field of pitching such as a ballpark, a plurality of camera apparatuses 100 may be spaced apart from each other by a preset shooting angle. The camera device 100 can generate a pitching image by shooting a pitching process until the pitcher hits the ball and the batter hits the ball or until the catcher catches the ball and outputs the generated pitching image to the server 200. [ Lt; / RTI > Then, the 3D helmet image generating unit 221 projects the image photographed by the camera apparatus 100 in two-dimensional coordinates, and displays each two-dimensional image, a world coordinate system and camera parameters (for example, Distance between the camera devices) can be used to generate a 3D helmet image, which is a 3D image.

The 3D pitching image generating unit 221 may transmit the 3D pitching image generated as described above to the control unit 220, the interval setting unit 223, the 3D pitching image processing unit 225, or the storage unit 230.

Next, the interval setting unit 223 can classify or set the 3D pitching images into a plurality of intervals according to the time sequence. For example, the interval setting unit 223 may set the 3D pitching image as a first interval and a second interval according to a time sequence. The first section and the second section may be sections that are divided so that the viewer can view the pitching image with the same feeling as the viewer sees from the viewpoint of the batter.

An example of such interval setting will be described with reference to FIGS. 4 and 5. FIG. Figs. 4 and 5 are diagrams illustrating an operation of classifying the trajectory of the pitching site into two sections in order to process the pitching trajectory image.

Referring to FIGS. 4 and 5, when a pitcher throws a pitch at a pitching position, the pitch of the pitcher is not changed until the predetermined time, so that the pitch of the pitcher is watched. Then, if the ball gets closer to the batter, the batter has to hit the ball, so the line of sight focuses on the ball, and the attitude of the batter and the line of sight of the face change somewhat. Particularly, the change of the attitude of the batter and the line of sight of the face can be largely changed as compared with the case of a change of movement such as a curveball.

Accordingly, the interval setting unit 223 can classify the 3D helmet image into at least two intervals based on the predetermined condition based on the above-described object. This predetermined condition may be, for example, time information of a break point or play period information for distinguishing the first section and the second section in the 3D helmet image.

According to a non-limiting embodiment, the time information or the playback period information of the above-mentioned turning point may be set by accumulated statistical data, a predetermined policy or machine learning, but is not limited thereto.

According to some embodiments, the interval setting unit 223 may set the 3D pitching image generated by the 3D pitching image generating unit 221 to a first locus image corresponding to the first region and a second locus image corresponding to the second region, It can be classified into images. In this case, the interval setting unit may be configured to reproduce or output the 3D helmet image in the direction in which the batter watches (e.g., rotate or change the composition of the 3D helmet image).

Referring again to FIG. 2, the 3D helmet image processing unit 225 may process the 3D helmet image so that the ball object and the background object of each trajectory image move in the classified trajectory image based on the viewpoint of the batter. Details of such a machining operation will be described later with reference to FIGS. 6 to 9. FIG. The 3D helmet image processing unit 225 can transmit the processed 3D helmet image to the control unit 220, the image transformation processing unit 227, or the storage unit 230.

Next, the image transformation processing unit 227 can perform transformation processing of the processed 3D pitch image. According to various embodiments, the image transformation processing unit 227 can process the second locus image as a slow motion region, and can visualize a virtual locus of the ball object moving in the slow motion region. The image transformation processing unit 227 can transmit the deformed 3D pitch image to the control unit 223 or the storage unit 230.

On the other hand, although not shown, the server 200 may further include a synchronization unit. This synchronization unit can synchronize the pitching-related image information received from each camera apparatus 100 to generate a 3D pitching image. However, if various embodiments of the present invention assume a state in which synchronization is already performed, the synchronization unit 223 may be inactivated or omitted in FIG.

The storage unit 230 may store data received or generated from the control unit 220, the server 200, or other components of the pitch trajectory imaging system 10. The storage unit 230 may include, for example, a memory, a cache, a buffer, and the like, and may be composed of software, firmware, hardware, or a combination of at least two of them.

According to various embodiments, the storage unit 230 may include a camera device DB 231, an image DB 233, and a user DB 235. The camera device DB 231, the image DB 233, and the parameter DB 235 are shown as being separated on the storage unit 230, but the present invention is not limited thereto and may be configured as one module.

The camera device DB 231 may include hardware information related to the camera device 100, software information, and identification information of each camera device 100. Such hardware information, software information, and identification information may be stored in the implementation of the three-dimensional information obtaining system 10 or may be updated by changing or adding the camera device 100 at any time.

The image DB 233 may include image information received from the camera device 100. [ For example, the image information received from each camera device 100 may be classified or mapped and stored in the image DB 233 according to a specific viewpoint or a pitching operation. However, the present invention is not limited thereto.

The image DB 233 includes a 3D helper image generated by the 3D helper image generation unit 221, the section setting unit 223, the 3D helper image processing unit 225, and the image transformation processing unit 227, And associated metadata (e.g., log information).

The user DB 235 may store body information related to a player (e.g., pitcher, batter, etc.). The body information may include, but is not limited to, the height (height) of the athlete, the weight, distance information from the floor to the eyes, and the like.

According to various embodiments, the user DB 235 may provide the body information of the athletes to the 3D pitching image processing unit 225 in response to a request from the 3D pitching image processing unit 225.

The 3D pitch image generation unit 221, the interval setting unit 223, the 3D pitch image processing unit 225 and the image transformation processing unit 227 logically or functionally perform the respective functions of the control unit 220 of the server 200 It may be a functionally classified configuration. Accordingly, the 3D pitch image generation unit 221, the interval setting unit 223, the 3D pitch image processing unit 225, the image transformation processing unit 227, and the control unit 220 may be configured as one module.

The functions of the 3D pitch image generation unit 221, the segment setting unit 223, the 3D pitch image processing unit 225, the image transformation processing unit 227, and the control unit 220 are stored in the storage unit 230 (e.g., memory) In the form of a routine, an instruction, or a program stored in memory.

In addition, such routines, instructions or programs may also be stored on a computer readable storage medium. Such a storage medium includes all kinds of storage media in which programs and data are stored so that they can be read by a computer system. Examples include ROMs (Read Only Memory), Random Access Memory, CD (Compact Disk), DVD (Digital Video Disk) -ROM, magnetic tape, floppy disk, optical data storage device, . Such storage medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.

FIG. 3 is a flowchart illustrating an operation of generating and processing a pitch image in the server 200 according to various embodiments of the present invention.

First, in step S310, the server 200 can receive photographed images of a pitching scene from a plurality of camera apparatuses. To this end, a plurality of camera apparatuses 100 arranged at a pitching site such as a ball park can shoot a ball moving at a predetermined speed in real time, periodically or for a predetermined time, (200).

Next, in step S330, the server 200 may generate a 3D pitching image. Such a pitching image may include a ball object and a background object.

Next, in step S350, the server 200 classifies the first trajectory image corresponding to the first section and the second trajectory image corresponding to the second section according to the time sequence in the direction in which the batter of the pitching site looks .

Next, in step S370, the server 200 may process the 3D helmet image based on the viewpoint of the batter and the classified image. Specifically, the server 200 can process the 3D helmet image so that the ball object and the background object of each trajectory image in the classified first trajectory image and the second trajectory image move based on the viewpoint of the batter have.

As described above, the three-dimensional pitch image is classified into a plurality of sections, and the 3D image of the pitch is reproduced at the viewpoint of the batter, so that the image graphics in each section are processed differently, Can be effective.

6 is a flowchart illustrating an operation of processing a first locus image in the server 200 according to various embodiments of the present invention. Each of the steps of FIG. 6 may be various embodiments of step S370 of FIG. 3 described above. In addition, the first locus image may correspond to the pitch image from the time when the pitcher throws the ball to the region corresponding to the second locus image.

First, in step S610, the server 200 may fix a background object of the first locus image. Specifically, the server 200 may change the viewpoint of the first locus image (e.g., rotate the image) so that the background object does not move in the 3D helper image to be reproduced or output.

In step S630, the server 200 may set the background object of the first locus image as a reference point. In step S650, the server 200 may process the first locus image so that the blank object of the first locus image moves. That is, the server 200 sets at least a part of the background object (for example, a specific point) as a reference point in a state in which the background object of the first locus image is fixed as a composition that can synchronize the viewers and the viewers' It is possible to process the first locus image so that a relatively moving ball object is output from the image.

Thus, in the first locus image processed (e.g., in a compositional change) based on the viewer's viewpoint and the batter's viewpoint, the background object can be processed so as to appear to move slightly in a state in which the background object is fixed. Such a machining operation does not change the content of the actual trajectory of the 3D helmet image which is the raw data, but it does not change the position of the 3D helmet image in the corresponding section so as to show the same visual effect as that of the viewers and the viewers, This can mean a modeling operation that makes changes.

Through the processing of the first trajectory image as described above, rather than gazing forward with respect to the ball in the initial trajectory of the ball thrown by the pitcher, the actual information about the path of the ball roughly gazing at the overall background, Can be shared.

7 is a flowchart illustrating an operation of processing a second locus image in the server 200 according to various embodiments of the present invention. Each of the steps of FIG. 7 may be various embodiments of step S370 of FIG. 3 described above. The second trajectory image may be a pitch image corresponding to a section from the second trajectory image until the batter hits the ball or the catcher catches the ball. For convenience of explanation in Fig. 7, description will be made with reference to the contents of Figs. 8A and 8B. FIGS. 8A and 8B are views illustrating an example of a 3D helmet image processed according to the viewpoint of the batter in the server 200 according to various embodiments of the present invention.

The server 200 can set the blank object of the second locus image as a reference point in step S710, and place the blank object within the predetermined area of the second locus image in step S730. In step S750, the server 200 may process the second locus image so that the background object moves on the basis of the blank object.

The second trajectory image can be processed as a time point in which both the ball object and the background object move because the batter changes the line of sight relatively more than the first section in order to strike the ball in the second section. In this case, the batter will focus on the ball rather than the background to hit the ball. In order to reflect the viewpoint of the batter position, the server 200 can set a reference area, which is a predetermined area of the second locus image, and can arrange the blank object in the set reference area.

Here, according to some embodiments, the server 200 may set the reference region based on the body information related to the batter. For example, the server 200 can set the reference area by referring to the internal database or external information, such as the height of the batter, distance information from the bottom to the eyes, and the like. As a result, it is possible to appropriately reflect the viewpoint of the pitcher as the batter has different physique conditions.

The server 200 may process the second locus image so that the second locus image moves in at least a part of the second locus image with respect to the blank object set as the reference point. In this case, the ball object may also be moved within a predetermined area, and the motion of the ball object and the background object may be a motion reflecting the viewpoint of the batter close to the batting event.

As a specific example, the contents of the locus images in the second section, that is, the second locus images, are shown in Figs. 8A and 8B.

In FIG. 8A, the pitching scene 803_A in which the distance between the viewpoint 802 of the batter and the ball object 801 in the second section is L1 is shown. In this case, the screen 805_A of the second locus image reflecting the pitching scene 803_A may include a blank object 801_A, a background object 809_A, and a reference area 807. [

8B shows a pitching scene 803_B in which the distance between the viewpoint 802 of the batter and the ball object 801 in the second section is L2. As shown in FIG. 8B, it can be seen that the distance L2 between the viewpoint 802 of the batter and the ball object 801 is closer to the distance L1 of FIG. 8A, and the position of the ball object 801, And it can be confirmed that it has fallen downward.

The screen 805_B of the second trajectory image reflecting the pitching scene 803_B includes a blank object 801_B whose size and position have been changed and a background object 809_B whose position has been changed within the same reference area 807 .

8A and the screen 805_B of the second locus image of FIG. 8B, the batter moves downward as the ball gradually approaches, and then the point of view is continuously adjusted to the ball do. Then, on the visual screen of the batter position, the moving ball may be located in a specific space such as the center of the field of view. As the ball gets closer, the size of the ball increases on the visual screen, and the surrounding background rises relatively as the batter hits the head.

Therefore, the server 200 can process the 2-trajectory image to reflect the viewpoint of the batter through the second trajectory image screens 805A_805B. As in the case of the first locus image described above, the processing operation of the second locus image does not change the content of the actual locus of the 3D helmet image, which is the low data, and does not change the visual effect This means modeling work that changes the composition such as position movement or rotation of the 3D helmet image in the corresponding section to be seen.

Through the processing of the second trajectory image as described above, when the ball thrown by the pitcher is close to the batter, the batter can share the batting practice information that focuses the ball as close as possible to the ball rather than gazing at the surrounding background, An effect can be obtained.

9 is a flowchart showing an operation of transforming a second locus image in the server 200 according to various embodiments of the present invention. According to various embodiments, each of these steps of FIG. 7 may be various embodiments of step S750 of FIG. 7 described above.

According to some embodiments, in step S910, the server 200 may transform the second locus image into a slow motion region. For example, the server 200 can reproduce an image at the original pitching speed up to the first locus image, and at a lower speed (e.g., slow motion) than the pitching speed of the first locus image from the second locus image. The object and the background object can be deformed to move.

According to some embodiments, in step S930, the server 200 may visualize a virtual trajectory in which a blank object of the second locus image moves. For example, the server 200 can visualize a virtual trajectory of a second trajectory image of a ball object using a UI line.

According to the embodiments described above, the motion of the trajectory of the pitching image in a specific section adjacent to the batter is subjected to specific motion processing or visualization processing, so that the viewer has the effect of concentrating on how the batter watches the ball .
