Dedicated device-type store terminal 200 of the present invention is a plurality of cameras 210, video storage 220, video transmission unit 230, member management unit 240, the user interface unit 250 and the control unit 260 It includes.

Looking at each component, the camera 210 can be used without limitation as long as it has a function to shoot and transmit a video. For example, a CCD (Charge-Coupled Device) image sensor mainly used in the digital camera 210 or the like, or a Complementary Metal-Oxide-Semiconductor (CMOS) image sensor mainly used for incorporation of small devices such as mobile phones, etc. 210). The CCD image sensor or CMOS image sensor may be selectively used in consideration of speed, power consumption, image quality, placement with other components, and the like. The camera 210 is installed one for each billiard table in the billiard room to shoot a video game billiards and transmits to the video storage unit 220.

The video storage unit 220 stores a billiard game video photographed by the camera 210, and may be connected to the camera 210 by wire or wirelessly to receive a video. The video storage unit 220 stores a set of video frames from the start point of the billiard game to the end point as one video file.

The video transmission unit 230 is a device for transmitting each video file stored in the video storage unit 220 to the billiard game video classification device 300. The video file may be transmitted at the request of the billiard game video classification apparatus 300. However, since the technical feature of the present invention distinguishes the success part video and the failure part video from the billiard game video, the default is When one video file is completed, the completed video file is transmitted to the billiard game video classification device 300 even if there is no request from the billiard game video classification device 300.

The member manager 240 is a device for managing user information using the billiard game video classification device 300 according to the present invention. The user may be a registered member or there may be an unregistered one-time user. The registered member stores information on the billiard game history of the member, billiard game video information played by the member, learning history, etc., and transmits the corresponding information when requested by the billiard game video classification device 300, and the user interface unit 250 When the information inquiry request is inputted through), the relevant information can be displayed. In addition, for a one-time user, a temporary ID is issued so that the user can access the billiard game video information later accessed by accessing the web server 400 or input the position of the billiard ball into the simulator from the played billiard game video. do. In this case, the temporary ID may be displayed on the user interface 250 or remotely transmitted to a mobile device such as a mobile phone.

The network camera type shop terminal 200 of the present invention includes a camera 210 and a video transmitting unit 230. The camera 210 may use a CCD image sensor or a CMOS support sensor as in the case of a dedicated equipment-type store terminal 200. Since the network camera-type store terminal 200 does not have a separate storage space, the video frame shot through the video delivery unit 230 is directly transmitted to the billiard game video classification device 300.

4 is a block diagram showing the internal configuration of the billiard game video classification device 300 of the present invention.

Billiards game video classification device 300 of the present invention is a video receiver 310, a video classification unit 320, a successful part video storage unit 330, a failed part video storage unit 340, the service unit 350 and the management unit 360.

Looking at each component, the video receiving unit 310 is a device for receiving and storing the billiard game video from the store terminal 200 or other means other than the store terminal 200, such as a mobile storage device, the network 500. . If the store terminal 200 is a dedicated device-type store terminal 200, the video storage unit 220 of the store terminal 200 stores a set of video frames from the time point at which the billiard game starts to the end point in one video file. Since it is completed and transmitted, match the member ID or temporary ID and the transmitted video file and save it immediately. When the store terminal 200 is a network camera type store terminal 200, the video transmission unit 230 of the store terminal 200 transmits a video frame photographed during a billiard game in real time, and thus, the video receiving unit 310. ) Collects the delivered video frames, completes them as video files, and matches and stores the member ID or temporary ID with the completed video file. If the billiard game video is received through other means than the mobile terminal 200, such as the mobile storage device 500, the store immediately.

The video classifying unit 320 divides the billiard game video stored in the video receiving unit 310 into a partial video for each shot, and classifies the successful partial video and the failed partial video according to whether each shot succeeds or fails. The video files classified by the video classifying unit 320 may be deleted by the video receiving unit 310 to efficiently use the storage space. The method of dividing the video into the partial video for each shot and the method for dividing the partial video for each shot into the successful partial video and the failed partial video in the video classifying unit 320 will be described in detail later.

The success portion video storage 330 and the failure portion video storage 340 are devices for storing the success portion video and the failure portion video classified by the video classification unit 320, respectively. The successful partial video storage unit 330 and the failed partial video storage unit 340 serve to provide a corresponding partial video when requested by the service unit 350.

The service unit 350 reads the success part video from the success part video storage unit 330 when the user accesses the web server 400 to download the success part video or to simulate using the failure part video. 400, or extracts the position of the billiard ball from the first video frame of the failed part video and delivers it to the simulator of the web server 400.

The management unit 360 is a device that manages the store terminal 200 and the billiard game video classification device 300. The store terminal 200 checks whether the store terminal 200 is normally operated, stores and manages member information input through the store terminal 200, and generates and issues a temporary ID for the non-member. As for the billiard game video classification device 300, the video receiver 310, the video classifier 320, and the service unit 350 divide the billiard game video into partial videos, and convert the partial video into a successful partial video or a failed partial video. After classification, the location information of the billiard ball extracted from the successful part video file and the failed part video is controlled to be provided to the web or the simulator.

5 is a block diagram showing the internal configuration of the web server 400 of the present invention. The web server 400 of the present invention includes a network device 410 and a database 420. The network equipment 410 connects the web server 400 to the user terminal 100, the store terminal 200, the billiard game video classification device 300, and the wired / wireless network 500 to the user from the web server 400. Provide web services and web pages. The database 420 is a device for storing data necessary for a web service. The web server 400 enables the user to run the simulator through a web page, and the initial position of the billiard ball provided in the simulator is provided by the service unit 350 of the billiard game video classification device 300.

Next, a method of classifying a billiard game video into a successful part video or a failed part video in the video classifying unit 320 of the present invention will be described. In the present invention, after the billiard game video is divided into partial videos for each shot, the divided partial video is classified into a successful partial video and a failed partial video.

First, the billiard game video is divided into partial videos. If the entire billiard game video is defined as FI and the partial video by the i shot is defined as FI _i , FI = {∀ i | FI _i }. The FI _i is distinguished by determining whether or not there is a movement of a billiard ball in the video. For example, when the water polo starts to move, the start point of the FI _i becomes, and when all the billiard balls in the pool table stop, the end point of the FI _i . Becomes Wherein there is be of a video FI _i is again divided into video frames, FI _{i, j} to define when the j-th frame of video _i FI, FI _i ∀ j = {| FI _{i , j} }

Next, a method of classifying a partial video FI _i into a successful partial video or a failed partial video will be described. In the billiards game, there are cases where the water polo is made of white balls and yellow balls, and the water polo is made of white balls without dots (hereinafter referred to as 'white balls') and white balls with dots (hereinafter referred to as 'dot balls'). do.

When the water polo is white ball and yellow ball, the first part video FI _i , the i part video, and the second part video FI _{i +1} , the i + 1st part video, are compared whether FI _i is a success part video or a failure part video. This can be seen. If this shot is successful in the billiards game, the water polo for the next shot will not change. If it fails, the water polo for the next shot will be changed. Therefore, if the color of the water polo is different from white and yellow, the success of this shot can be determined by judging whether the color of the water polo changes in this and the next shot.

If the camera 210 of the store terminal 200 has a motion detection function, the water polo port is first identified for each partial video, and the color value of the water polo is extracted by extracting the color value of the pixel where the water polo is located in the first video frame of the partial video. I can figure it out. For example, if the water polo is white ball, hex code #FFFFFF is extracted, and if yellow ball is # FFFF00, the color of the first sphere video FI _i and the second partial video FI _{i +1} can be known. If the color of the bulb is changed from white to yellow or from yellow to white, the first part video FI _i is classified as a failure part video. If the color of the bulb is not changed, the first part video FI _i is classified as a success part video and saved. do.

On the other hand, even if the camera 210 of the store terminal 200 does not have a motion detection function, it is possible to determine the color of the water polo by the image processing. In this case, the first two video frames are required for each partial video. _{Colors of the beginning} and the _beginning of the first partial video FI _i and the second partial video FI _{i +1} when the video frames FI _{i , 1} , FI _{i , 2} , FI _{i +1,1} and FI _{i +1,2} In order to find out, the difference between the color value of the second video frame and the color value of the first video frame is calculated for each partial video. Since each billiard ball and billiard table in the first video frame and the second video frame except for the first sphere are stationary, the difference between the color values of the first video frame and the second video frame is 0 except for the position of the first sphere. do. For example, the color value of the pool table, the green # 00FF00 and the first pitch is the huingong one time, FI _i, subtracting the FI _{i, 1} eseo ₂ man # FF00FF where the huingong of FI _{i, 2,} all the rest 0 Since it has the following values, it can be seen that the focus of the first partial video FI _i is white. And find out the color of the first pitch of the second portion of the video FI _{i + 1} in the same way, the first portion and the second video FI _i a _i of a video FI first partial video FI _i using the color change of the first pitch of ₊₁ As described above, it may be classified as a success part video or a failure part video.

When the partial video classification method is sequentially performed on the first partial video and all the partial videos until FI _i becomes the last partial video, the classification of the billiard game video FI according to the first embodiment ends.

Water polo can be divided into two cases, white ball and divination. The first is when the dots are visible, and the second is when the dots are not visible. In the case where the dots are visible, the partial video is converted into a successful or failed part video by comparing whether there is a change in the water polo point, similar to the case where the water polo is white and yellow. Can be classified.

When a ball the cue ball huingong points are not visible spots, part of the video FI _i of analyzing the video frame first water polo is the other side of the second water polo has succeeded in only part of the video FI _i If you crash all the server object ball if you do not crash It is classified as a partial video, and in other cases, the partial video FI _i should be classified as a failed partial video. Specific methods are as follows. For convenience, it will be described as a case of a four-ball billiards game played with two water polo and two red ball.

The case where FI _i is classified as a failure part video is as follows.

1) compared to the video frame and the video frame of the end of the FI _i FI _i starting time point, in the absence of the change in position of the remaining three billiard balls than the first sewer (if not matched none)

2) when compared to the video frame and the video frame of the end of the FI _i FI _i starting point, there is no change in any of the positions of the two jeokgu (if align the jeokgu 1)

When 3) FI to _i compares the video frame and the FI _i video frames of the end of the start point, the position of the two jeokgu is no change, only the position of the other side of the second sewer byeonhaeteul (when the peer of the second sewer )

4) as compared to the FI _i video frame of the start video frame and FI _i at the end of the time, the almost all the positions of the three remaining billiard balls than the first sewer valve, the first sewer is the other side of the second sewer in progress Failed to match or 2 red balls

For a two-1) to 3) is simple, since the FI _i is classified as a failure of the video only by identifying the cue ball from the positions of the four video frames of the video frame and the start point of the _i FI FI _i end. However, in case of 4), it is necessary to find out by analyzing the video frame of FI _i whether the first water polo matches the second water polo of the opponent or both red balls.

Hereinafter, a method of classifying FI _i as a successful partial video or a failed partial video will be described based on the case where the first water polo is white ball in the case of 4).

In the video frame FI _{i , j} the coordinates of the white ball's center (x_W1 _{i , j} , y_W1 _{i , j} ), the coordinates of the ball's center (x_W2 _{i , j} , y_W2 _{i , j} ), and the coordinates of the first red ball's center (x_R1 _{i , j} , y_R1 _{i , j} ), and the center coordinates of the second red ball are defined as (x_R2 _{i , j} , y_R2 _{i , j} ).

The method of obtaining the center coordinates of the billiard ball in the video frame FI _{i , j} is as follows. Figure 6 shows the histogram according to the position of the billiard ball in the pool table. For convenience, if the xy coordinate system 620 is defined as the origin of the center of the billiard table in FIG. 6, the histogram of the white ball 610 located in the upper right is X-axis histogram 630 H _X (x) and the billiard table top of the billiard table right side of FIG. 6. Is the same as the Y-axis histogram 640 H _Y (y). When the histogram of the white hole 610 is obtained, the median is taken from each of the X and Y axis histograms to determine the center coordinate of the white ball 610.

In the present invention, the collision of the white ball is determined by detecting a change in the tilt (hereinafter, referred to as 'tilt') of the direction in which the white ball travels in the x-y coordinate system 620 on the billiard table.

For example, in order to obtain the first slope of a white ball in the partial video FI _i , it is necessary to know the coordinates of the white ball in the first video frame FI _{i , 1} and the coordinates of the white ball in the second video frame FI _{i , 2} . Applying the method of calculating the center coordinates of the billiard ball using the above histogram to FI _{i , 1} and FI _{i , 2} , the center coordinates of the white ball are (x_W1 _{i , 1} , y_W1 _{i , 1} ) and (x_W1 _{i , 2} , y_W1 _{i, 2} ). When the initial slope S _{i , 1} of the white ball is obtained from the center coordinates of the white ball, Equation 1 is obtained.

In the same manner, the slope S _{i , k} of the white ball is also obtained for the arbitrary k th video frame FI _{i , k} and the k + 1 th video frame FI _{i , k + 1 as shown} in Equation 2 below.

If there is a conflict huingong slope S _{i, k} is because there is no change, the slope S _i, by comparing the video frame of the time _k is changed if huingong a conflict jeomgong, that hit the jeokgu or rail of the pool table (rail) You can see if it hits and reflects.

For example, if the slope of the white ball remains unchanged up to the mth slope S _{i , m} , but changes from the m + 1th slope S _{i, m + 1} , then the video frames F _{i , m + 1} and F _{i , m + 2} You can see that the white ball collided with something in between. F _i, the coordinates of the center of huingong from the _{m + 1 (x_W1 i, m} + 1, y_W1 i, m + 1) obtains, F _i, the coordinates of the center of huingong in the _{m + 2 (x_W1 i, m} + 2, y_W1 i _{, m + 2} ), if the distance between the center coordinates and the billiard table rail is smaller than the error range d in both center coordinates, the change of the m + 1 th slope S _{i , m + 1} is caused by the white ball colliding with the pool table. Judging by it.

If the white ball does not collide with the pool table, it is next judged whether or not it collided with another billiard ball, and whether or not the collision with another billiard ball is determined by the distance between the center coordinate of the white ball and the center coordinate of the other billiard ball in the video frame. do. For example, in the video frame F _{i , m + 1} , the center coordinates (x_W1 _{i , m + 1} , y_W1 _{i , m + 1} ) of the white ball and the center coordinates (x_W2 _{i, m + 1} , y_W2 _{i , m + 1} ) The center coordinates of the white ball (x_W1 _{i, m + 2} , y_W1 _{i , m + 2} ) and the center coordinates of the astronaut (x_W2 _{i , m + 2} , y_W2 _{i , m + 2} ) in the distance and video frames F _{i , m + 2} If the distance between them is smaller than the billiard ball diameter D + error range d, it is determined that the white ball collides with the point ball. That is, when the distance l between the white ball and the center coordinate of the divination satisfies the conditions of Equations 3 and 4 below, the white ball is determined to collide with the divination, and the partial video FI _i is regarded as a failed partial video. Sort and save.

To determine whether a white ball collides with a red ball, use the same method as when determining whether a white ball collides with the above ball. However, since the red ball must match both, after the white ball hits the first red ball, the center coordinates of the first red ball are also tracked along with the center coordinates of the white ball. If the white ball realigns the first red ball, the tracking continues. Only when the white ball hits the second enemy ball is classified and stored as a success part video.

When the partial video classification method is sequentially performed on the first partial video and all the partial videos until FI _i becomes the last partial video, the classification of the billiard game video FI according to the second embodiment ends.

7 and 8 are flowcharts illustrating a process of the billiard game video classification method according to the present invention. The above description will be described below with reference to FIGS. 7 and 8.

1) Step S1: The billiard game video is divided into partial videos.

2) Step S2: Insert 1 into i to select the first partial video FI ₁ .

3) Step S3: From the first partial video FI ₁ , it is determined whether the water polo is white ball and yellow ball, and the white ball and divination ball. If the water polo is white ball and yellow ball, the process proceeds to step S11. do.

4) Step S11: Compare the FI _i and the next part video FI _{i +1} to see if the color of the water polo is changed, proceed to step S12 if the color of the water polo does not change, and proceed to step S13 if the water polo color changes. .

5) Step S12: Partial video FI _i is classified and stored as a successful partial video, and step S14 is performed.

6) Step S13: The partial video FI _i is classified and stored as a failed partial video, and step S14 is performed.

7) Step S14: It is determined whether FI _i is the last video, and if the last video is terminated, the process proceeds to S15 if it is not the last video.

8) Step S15: Increases the value of i by 1 and proceeds to Step S11.

9) Step S21: Comparing the video frame of the start point of the partial video FI _i and the video frame of the end point, proceed to step S25 if the following three cases.

① FI _i compared to the video frame and the video frame FI _i of the end of the start point, in the absence of the change in position of the remaining three billiard balls than the first sewer (if not matched none)

② compared to the video frame of the FI and FI _{i i} starting point video frame of the end, when there is no change in any of the positions of the two jeokgu (if align the jeokgu 1)

③ compared to the video frame of the FI _i start video frame and FI _i ends at the time point, the position of the two jeokgu is no change, when only the position of the other side of the second sewer byeonhaeteul (if matched, only the other side of the second sewer)

10) step S22: extracting the moving image frame at the moment when the slope of the direction in which the first water polo proceeds changes.

11) Step S23: If it is determined that the first water polo has collided with the opponent's second water polo, proceed to step S25.

12) Step S24: If it is determined that the first water polo has collided with both the first red ball and the second red ball, proceed to step S26, otherwise proceed to step S25.

13) Step S25: The partial video FI _i is classified and stored as a failed partial video, and step S27 is performed.

14) Step S26: The partial video FI _i is classified and stored as a successful partial video, and step S27 is performed.

15) Step S27: It is determined whether FI _i is the last video, and if the last video is terminated, the process proceeds to S28 if it is not the last video.

16) step S28: increases the value of i by 1 and proceeds to step S21.

In this manner, when the partial video FI _i is classified as a successful partial video or a failed partial video with respect to the billiard game video FI and stored in the successful partial video storage unit 330 or the failed partial video storage unit 340, respectively, The simulator 400 may be connected to the server 400 to download a success partial video or to use a failure partial video. The simulator implements the simulation environment by inputting the center coordinates of the billiard balls extracted from the first video frame of the failing part video, but the configuration of the simulator itself is beyond the scope of the present invention, and thus a detailed description thereof will be omitted.
