First, the camera 100 generates an image by photographing a billiard play of a user's current shot. In this case, the camera 100 may be installed above the billiard table.

Meanwhile, the camera 100 may generate an image for each shot of the user by detecting the movement of the water polo. For example, the camera 100 may generate an image by detecting a shot from a time point in which the movement of the billiard ball starts to a time point in which the movement of the billiard ball ends.

The camera 100 transmits the captured image by communicating with the online billiard game device 200 according to the embodiment of the present invention by wire or wirelessly.

Next, the on-line billiard game device 200 according to the embodiment of the present invention receives a captured image of the billiard play of the current shot of the user received from the camera 100 to select the water polo of the next shot of the user or the opponent Output

Specifically, the online billiard game device 200 according to an embodiment of the present invention analyzes the received shot image and extracts the movement path of the water polo in the user's current shot, thereby determining whether the user's current shot is recognized as a score. do. Then, the water polo of the next shot of the user or the opponent is selected and output through the recognition of the score of the current shot and the preset water polo selection mode.

In addition, the online billiard game device 200 according to an embodiment of the present invention may store the game progress result for each user. For example, the online billiard game device 200 may store the user's highest score per inning, average score per inning, the number of foul shots, and the like. In this case, the inning refers to the progression time from the billiard game to the player shift.

The online billiard game device 200 may calculate and store the entire game result information in consideration of the user's previous game result, and calculate the user's average in consideration of the entire game result information.

On the other hand, according to an embodiment of the present invention, the online billiard game device 200 may be implemented in the form of a server or connected to a relay server (not shown) to match the players to play the billiard game in different spaces, You can also run an online billiard competition.

In this case, the display apparatus 300 may also output the player name of the next shot.

In addition, the display apparatus 300 may output the water polo information of the next shot and the name of the player through the included speaker. For example, the display device 300 transmits a comment "The player of the next shot is Kim Chul-soo. Kim Chul-soo's water polo is a yellow ball" through the speaker to transmit the water polo information and player information of the next shot to the system user. You can also provide

Next, the online billiard game device 200 according to the embodiment of the present invention will be described with reference to FIG. 2. 2 is a block diagram of an online billiard game device according to an embodiment of the present invention.

As shown in FIG. 2, the online billiard game device 200 includes a receiver 210, an extractor 220, a determiner 230, a selector 240, and an output 250.

First, the receiver 210 receives a captured image of the billiard play of the current shot of the user from the camera 100 installed above the billiard table.

Then, the extraction unit 220 extracts the movement path of the water polo in the current shot using the received captured image.

Next, the determination unit 230 determines whether the current shot is scored through the extracted water movement path.

Then, the selector 240 selects the water polo of the next shot of the user or the opponent according to the determination result of the scoring.

Specifically, when the user's score of the current billiards play is recognized, the selector 240 selects the water polo of the current shot as the water polo of the next shot. On the contrary, if the score of the current shot of the user is not recognized, the selector 240 selects the water polo of the next shot of the user or the opponent according to the preset water polo selection mode.

At this time, the water polo selection mode is a random mode for randomly selecting water polo, a difficulty selection mode for selecting only high or low water polo among two candidates, and an average mode for selecting water polo according to the user's billiard level among two candidates. It includes.

Here, the water polo selection mode may be set by receiving an input from a user, and detailed conditions of the mode may also be set by receiving an input.

For example, in the difficulty selection mode, while selecting the difficulty selection mode, the selector 240 may receive a detailed condition for selecting only water polo of high difficulty from the user or selecting only water polo of low difficulty.

As another example, in the average mode, the selector 240 may receive a billiard level range for selecting a ball of low difficulty and a billiard level range for selecting a ball of high difficulty while receiving a difficulty selection mode. At this time, the billiard level range may be preset.

On the other hand, if the difficulty selection mode or average mode is set in advance, the selector 240 extracts the position of the billiard ball at the end of the current shot. Then, the selector 240 extracts a plurality of scoring paths using the extracted position of the billiard ball.

Then, the selector 240 calculates difficulty levels of the extracted plurality of scoreable paths, selects a water polo of the scoreable path corresponding to the highest difficulty among the calculated difficulty levels, or corresponds to the difficulty level according to the user's billiard level. Select the water polo of the scoreable path.

At this time, the selector 240 is a moving distance of the water polo for scoring, the number of times the water polo hits the cushion for scoring, the number of times the water polo hits the cushion of the billiard table before heating the object, Difficulties for a plurality of scoring paths may be calculated using at least one of the thickness of the water polo points of the apparatus for scoring.

Here, the billiards level of the user may be set by receiving an input from the user or by using the billiard play result of the user for a predetermined period.

The output unit 250 outputs information about the selected water polo to the display apparatus 300. In addition, the output unit 250 may output the player information of the next shot, the movement path information of the current shot, or the captured image to the display apparatus 300.

Hereinafter, the online billiard game method using the online billiard game device 200 according to the embodiment of the present invention will be described with reference to FIGS. 3 to 5. 3 is a flowchart of an online billiard game method according to an embodiment of the present invention.

As shown in FIG. 3, the receiver 210 receives a captured image of a billiard play of a user's current shot from the camera 100 installed above the billiard table (S310).

Then, the extraction unit 220 extracts the movement path of the water polo in the current shot using the received photographed image (S320). That is, the extraction unit 220 extracts the movement path of the water polo until the user stops after hitting the water polo using a cue (que).

At this time, the movement path of the water polo is a path from the user hits the water polo to the stop of the water polo, information about the number of times the water polo hits the cushion of the pool table during the movement process and when the water polo hitting the target ball In addition, the selector 240 may extract the movement path of the water polo through a pre-stored image analysis algorithm.

The determination unit 230 determines whether the current shot is scored through the extracted water movement path (S330). In this case, the determination unit 230 determines whether the current shot is scored according to a predetermined billiard rule.

For example, the judging unit 230 is determined to score three or more times to hit the cushion of the pool table before the water polo hits the second object ball (a ball that hits the first object ball after hitting). Billiard rules of the old game may be preset.

Then, the determination unit 230 determines that the current shot is the second shot through the information on the number of times the water polo hits the cushion of the pool table included in the movement path of the water polo and the time when the water polo hits the first and second objects. Before hitting the ball, the score is judged based on whether the player has hit the pool table three times or more.

Next, the selector 240 selects the water polo of the next shot of the user or the opponent according to the determination result of the scoring. In detail, when the user's score of the current billiard play is recognized, the selector 240 selects the water polo of the current shot as the water polo of the next shot (S340). In this case, even if two or more players play, the user scores, so the player of the next shot becomes the user.

On the other hand, if the score of the current shot of the user is not recognized, the selector 240 selects the water polo of the next shot of the user or the opponent according to the preset water polo selection mode (S350). In this case, when one person proceeds to play billiards, the player of the next shot becomes the user, and when two or more players play billiards, the player of the next shot becomes the opponent.

4 is a flowchart illustrating an operation S350 of FIG. 3 in detail.

As shown in FIG. 4, the selector 240 determines a preset water polo selection mode (S351). In detail, the selector 240 determines whether the preset water polo selection mode is a random mode, a difficulty selection mode, or an average mode.

At this time, if the random mode is previously set, the selector 240 randomly selects any one of the candidate water polo (S352). Here, the candidate water polo means a billiard ball that can be heated using a cue, and is determined according to a predetermined billiard rule. For example, in the case of a three-ball game using three billiard balls indicated by yellow, white, and red, the candidate water polo is a yellow and white billiard ball, and the selection unit 240 is a yellow or white billiard ball. Select one randomly as a water polo.

On the other hand, when the difficulty selection mode or average mode is set in advance, the selector 240 extracts the position of the billiard ball at the end of the current shot from the captured image (S353).

Then, the selector 240 extracts a scoreable path for each candidate water polo by using the extracted position of the billiard ball (S354). In this case, there may be a plurality of scoreable paths for each candidate.

Next, the selector 240 calculates a difficulty level of the extracted scoreable path (S355). Here, the selector 240 is a moving distance of the water polo for scoring, the number of times the water polo hits the cushion for scoring, the number of times the water polo hits the cushion of the billiard table before heating the object, Difficulties for a plurality of scoring paths are calculated using at least one of the thickness of the water polo points of the apparatus for scoring.

FIG. 5 is a diagram for describing operation S354 of FIG. 4. 5 (a) and 5 (b) are diagrams for explaining a method of calculating the difficulty level through the moving distance of the water polo for scoring. In the case of FIG. 5A, the moving distance of the water polo is longer than that of FIG. 5B until the score is recognized. Accordingly, the selector 240 determines that difficulty of FIG. 5A is lower than that of FIG. 5B. That is, the selector 240 determines that the difficulty of the water port is longer.

5 (c) and (d) are diagrams for explaining a method of calculating the difficulty level through the number of times the water polo hits the cushion of the pool table before the target ball is heated. In the case of (c) of FIG. 5, the apparatus hits the cushion once before the object is heated, or in the case of FIG. Accordingly, the selector 240 determines that the difficulty of FIG. 5C is lower than that of FIG. 5D. That is, the selector 240 determines that the higher the number of hits on the cushion before the target sphere is heated, the higher the difficulty.

5 (e) and 5 (f) are diagrams for explaining a method of calculating a difficulty level through a thickness in which a water polo heats a target sphere. In the case of FIG. 5E, the thickness of the water polo and the target sphere is greater than that of FIG. 5F. Accordingly, the selector 240 determines that the difficulty of FIG. 5E is lower than that of FIG. 5F. That is, the selector 240 determines that the difficulty is increased as the thickness of the water polo and the target sphere is thin.

5 (g) and (h) are diagrams for explaining a method of calculating difficulty through the location of our shop. In the case of Fig. 5G, our shop position is located closer to the center of the water polo than in Fig. 5H. Accordingly, the selector 240 determines that the difficulty of FIG. 5G is lower than that of FIG. 5H. That is, the selector 240 determines that the difficulty is higher as the location of the shop is located far from the center of the water polo.

On the other hand, when a plurality of scoreable paths are calculated for each of the candidate apparatuses, the selector 240 may determine the scoreable path having the lowest difficulty calculated among the plurality of scoreable routes for each candidate apparatus as the scoreable path of the apparatus. have.

For example, three scoreable paths have been calculated for water polo (A), with 10 points of difficulty, Route 1 10 points, Route 2 8 points, and Route 3 7 points. Assume that Then, the selector 240 determines the lowest point as the difficulty of the water polo (A).

Then, the selector 240 selects the water polo of the scoreable path corresponding to the highest or lowest difficulty among the calculated difficulty levels or selects the water polo of the scoreable path corresponding to the difficulty according to the billiard level of the user or the opponent (S356). ).

For example, assume that the difficulty selection mode is set and the difficulty is set to high. Then, the selector 240 selects the candidate water polo with the difficulty calculated among the first water polo and the second water polo as the water polo for the next shot.

As another example, it is assumed that an average mode is set, a billiard level 300 or less is selected to select a low difficulty, and a billiard level 300 or more is set to select a high difficulty. In this case, when the preset user billiard level is 250, the selector 240 selects a candidate water polo having a low difficulty calculated among the first water polo and the second water polo as the water polo for the next shot.

Next, the output unit 250 outputs information on the selected water polo to the display device 300 (S360).

According to an exemplary embodiment of the present invention, the billiard game player can select and provide a water polo, so even if only one player can play the billiard game. In addition, when two or more players play a game of billiards, they can select water polo according to the game skills of each other.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
