In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a block diagram showing a billiards training system according to the present invention, the billiards training system 100 according to the present invention includes an image acquisition means 110, a control means 120, and a display means 140. .

First of all, the display means 140 is provided as any one of a common monitor or a cathode ray tube (CRT) such as a TV CRT, or an LCD, a TFT-LCD, a PDP, a flexible display, or a head mounted display (HMD). . The display means 140 is disposed on the billiard table 10 that does not interfere with the billiard game, for example, the user can easily look at the billiard game. The display means 140 provides the user with signals output from the image acquisition means 110 and the control means 120, which will be described later, as an image.

The image acquisition unit 110 photographs the upper surface of the bed 12 of the billiard table 10, that is, the play surface 16 of the plane surrounded by the rail 14, and the billiard balls placed on the play surface 16. . To this end, the image acquisition means 110 is fixed to be spaced apart from the top of the bed 12 so as not to interfere with the display means 140 while viewing the entire play surface 16. The image acquisition means 110 is a still image (P1; or "still") of the billiard balls with the play surface 14, that is, the still first and second water polo, and the still first and second object balls. Video signal). Furthermore, the movement which photographed the 1st or 2nd water port which hits and moves with a cue together with the play surface 16, and the 1st, 2nd object ball which hits and moves to a 1st or 2nd water port An image (not shown; hereinafter referred to as "mobile image") is output as a signal.

Meanwhile, the still image P1 and the moving image are determined by the first memory 112 provided in the image acquisition means 110. In the first memory 112, images captured by the image acquisition unit 110 are stored in units of frames. At this time, if the position of the billiard ball of the previous frame and the subsequent frame is the same and outputs it as a still image (P1). If the position of the billiard ball in the previous frame and the subsequent frame is different, this is output as a moving image. The still image P1 or the moving image of the billiard balls photographed as described above is output to the control means 120 and the display means 140 via either a wired or wireless communication network.

Preferably, the image acquisition means 110 is composed of a conventional vision camera. In FIG. 1, although the image acquisition means 110 having one vision camera is shown, it will be appreciated by all that the vision camera is not limited to one. More preferably, the first and second water polo are provided in white, or either one of the first and second water polo is provided in yellow, and the first and second object spheres are provided in red.

The control unit 120 outputs the scoring path based on the still image P1 output from the image acquisition unit 110, and similarly the moving image output from the image acquisition unit 110. And a second information processor 130 for outputting the cause of scoring failure based on the information.

The first information processing unit 122 includes a water polo determination unit 124, a scoring path data storage unit 126, a scoring path comparison determination unit 128, and a scoring path extraction unit 129.

The water polo determination unit 124 outputs as a signal a first comparison image P2 which is output from the image acquisition unit 110 and determines the water polo to hit the still image P1 provided as an image by the display unit 140 as a signal. The first comparison image P2 output from the correction determination unit 124 is composed of the crystal ball, the first and second object spheres, and the image of the play surface 16. The first comparison image signal is the scoring path comparison decision unit. And output to the display unit 140 and the display means 140. In this case, the first comparative video signal output to the display means 140 is provided to the user as an image by the display means 140 as shown in FIG. 3.

And the water polo to hit the water polo determination unit 124 is determined by the user's selective operation. That is, the user determines a ball to hit by using a conventional mouse, a keyboard, or a touch pad connected to the control unit 120 and the display unit 140, or the touch screen. Using the display means 140 made of a (touch screen) to determine the water polo to hit.

The scoring path comparing unit 128 compares the scoring path data stored in the scoring path data storage unit 126 based on the first comparison image P1 output from the water polo determining unit 124 and then scores a plurality of scoring paths. The image P3 is output as a signal. In other words, the scoring path comparison decision unit 128 extracts a plurality of scoring path data having location information similar to the location information of the crystal ball and the first and second object balls provided in the first comparison image P2. . At this time, the scoring expected path video signal is output to the scoring path extracting unit 129 and the display means 140. The scoring expected path video signal output to the display means 140 is displayed as shown in FIG. Is provided to the user as an image, the progress path (S1) of the crystal ball in the score prediction path image (P3). In FIG. 4, only two score prediction path images P3 are illustrated, but two or more score prediction path images P3 may be provided. In addition, the reason for outputting the plurality of scoring expected path images P3 in the scoring path comparing unit 128 is to provide an optimal scoring path, and another water polo not hitting on the scoring goal path image P3 is generated. If the position is to avoid it to be able to score.

On the other hand, the scoring path extracting unit 129 scores any one of the scoring predicted path images P3 determined by the user among the plurality of scoring predicted path images P3 output from the scoring path comparison determining unit 128, and the scoring path video signal. Will output The scoring path image signal output from the scoring path extracting unit 129 is output to the analyzing unit 136 and the display unit 140 which are causes of failure of the second information processing unit 130 described later. The display means 140 provides the scoring path image signal to the user as the scoring path image P4 as shown in FIG. 5. Meanwhile, the determination of the scoring path image P4 in the plurality of scoring expected path images P3 is made by the user's selective operation as in the determination of the water polo to hit.

As such, when the scoring path image P4 is provided by the display means 140 by the driving of the first information processing unit 122, the user guides the water polo determined according to the progress path of the water polo provided in the scoring path image P4. Play the game by hitting the determined water polo using a cue stick whenever possible.

On the other hand, the second information processing unit 130 includes a scoring determination unit 131, a decision tool proceeding path extraction unit 132 and a failure cause analysis unit 136 that is driven when the scoring fails. That is, the determination tool progress path extraction unit 132 and the cause of failure analysis unit 136 are driven when it is determined that the first object sphere or the second object sphere is not moved by the hit ball.

The score determination unit 131 compares the still image P1 of the billiard balls output from the image acquisition unit 110 and the moving image to determine whether to score. That is, by comparing the last frame taken of the still image P1 with the last frame taken of the moving image, if there is a change in the position of the first and second target spheres, the score is determined. If there is no change in position in any of the first and second objects, it is determined that the goal is failed. In this case, the scoring determination unit 131 may determine that the hitting ball throws the first goal ball or the second goal ball finely as a scoring failure. In addition, the scoring determination unit 131 may determine that the first object ball and the second object ball have a change in position even if the hit ball is hitting the ball that is not hit.

On the other hand, the crystal ball proceeding path extraction unit 132 outputs the second comparison image (P5) extracted the moving path (S2) of the crystal ball from the moving image of the billiard balls output from the image acquisition means 110 as a signal ( 6). Determination tool progress path (S2) in the moving image stores the moving image of the billiard balls in units of frames, after determining the degree of change depending on the position of the hitting ball on the previous frame and the position of the hitting ball on the subsequent frame Calculate the advancing direction of the water polo to extract the advancing path of the water polo. To this end, the determination tool progress path extracting unit 132 includes a second memory 134 that stores the moving image in units of frames. If there is no change in the position of the billiard balls in the previous frame image and the subsequent frame image stored in the second memory 134, it is determined that the billiard balls are stopped.

Although one preferred embodiment of extracting the waterway S2 of the water polo from the moving image has been described above, it will be appreciated by all that a method of extracting the waterway S2 of the water polo from the moving image is not limited thereto. .

On the other hand, failure cause analysis unit 136 compares the second comparison image (P5) output from the determination path progress path extraction unit 132 and the scoring path image (P4) output from the scoring path extraction unit 129 after (See FIG. 7), the cause of scoring failure is output as a signal. That is, the failure cause analysis unit 136 compares the progress path S1 of the crystal ball provided in the scoring path image P4 with the decision path progress path S2 of the second comparison image P5 to compare the cause of the scoring failure. Output as a signal. The score failure cause information output as described above is provided as an image by the display means 140 together with the scoring path image and the second comparison image. Preferably, the information about the cause of the score failure may be provided by voice.

On the other hand, the score failure cause information provided by the failure cause analysis unit 136 is classified into our shop and thickness failure information, rotational force failure information, and blow strength failure information.

When explaining the cause of the scoring failure in detail, first, the progress path (S2) of the decision ball proceeding after hitting the first target ball in the second comparison image (P5) is the decision tool progress path (S1) of the scoring path image (P4). ) Is judged to be our fault and thickness defect. In addition, if the angle of the crystal ball exiting the rail 14 after hitting the first target ball in the second comparison image (P5) is out of the ball path opening path (S1) of the scoring path image (P4) it is a bad rotational force To judge. And finally, when the crystal ball does not hit the first object sphere in the second comparative image (P5), or the crystal ball (S2) that proceeds hitting the first object sphere proceeds to the crystal ball of the scoring path image (P4) Although not guided along the path S1, it is determined that the blow strength is not good when the second target ball is not hit.

According to the scoring path image and the score failure cause information provided as described above, billiard beginners or beginners can easily acquire billiard skills and improve their strength through the score failure cause information.

In the following, the billiard training system 100 according to the present invention includes an image acquisition unit 110, a control unit 120 having first and second information processing units 122 and 130, and a display unit 140. The control method of the will be described.

8 is a flowchart illustrating a method of controlling a billiards education system according to the present invention. First, a still image P1 is output (step S210). The still image P1 includes the upper surface of the bed 12 of the billiard table 10, that is, the play surface 16 and the stationary billiard balls. The still image (P1) is taken and output by the image acquisition means 110 is fixedly spaced apart on the upper portion of the billiard table (10), wherein the image acquisition means (110) stores the captured image in units of frames, If there is no change in the position of the billiard balls in the previous frame and the subsequent frame image it is output as a still image (P1) of the billiard balls.

When the output of the still image P1 is completed as described above (S210), the scoring path image P4 is output based on the output still image P1 (step S220). The scoring path image P4 is processed by the first information processing unit 122 of the control unit 120, and then the image is output by the display unit 140 and provided to the user.

When the output of the scoring path image P4 is described in detail, first, the water polo to be hit in the still image P1 is determined, and the image of which the water polo is determined is output as the first comparison image P2 (step S222). After comparing the first scoring video P2 with the stored scoring path data and outputting a plurality of scoring expected path images P3 (step S224), the scorer scores any one selected from the plurality of scoring expected path images P3. The image is determined and output as the path image P4 (step S226).

The determination of the water polo to be hit (step S222) and the determination of the scoring path image P4 (step S226) are made by the user's operation. That is, when the still image P1 and the plurality of scoring predicted path images P3 provided as images to the display means 140 are output, the user may use a conventional mouse connected with the control means 120 and the display means 140. Determining the water polo and scoring path image (P4) to hit by using a mouse, a keyboard (key board), or a touch pad, or by using the display means 140 made of a touch screen The water polo and the scoring path image (P4) to hit are determined. In operation S224, the scoring path data having the location information similar to the location information of the crystal ball, the first object sphere, and the second object sphere provided in the first comparison image P2 is extracted, and the score prediction path image P3 is extracted. In the score prediction path image P3, the progress path S1 of the water polo for scoring is displayed.

As described above, when the scoring path image P4 is output (step S220), the user advances the game by hitting the water polo based on the scoring path image P4 (step S230).

On the other hand, when the game is progressed by the user (step S230), and outputs a moving image (not shown) of the billiard balls (step S240). The moving image is photographed and output by the image acquiring means 110 similarly to the still image P1, and the moving image includes the play surface 16 and the billiard balls moving. At this time, the image acquisition unit 110 stores the photographed image in units of frames, and outputs the moving image of the billiard balls if there is a change in the position of the billiard balls in the previous frame image and the subsequent frame image.

When the output of the moving image is completed in the above-described step (S240), it is determined whether the goal is scored by the hitting water polo (step S250). The determination of whether to score is determined in the second information processing unit 130 of the control means 120. The determination of whether to score is determined by comparing the still image (P1) of the billiard balls output from the image acquisition means 110 and the moving image. That is, by comparing the last frame taken of the still image P1 with the last frame taken of the moving image, if there is a change in the position of the first and second target spheres, the score is determined. If there is no change in position in any of the first and second objects, it is determined that the goal is failed.

If the score is recognized here, it is returned to the step (S210) of shooting the still image (P1) of the billiard balls together with the play surface (16). If the score is not recognized, the second comparison image P5 from which the moving path S2 of the water polo hit by the moving image is extracted (step S260).

Extracting the moving path (S2) of the hitting water polo in the moving image (step S260), after storing the moving image in the frame unit, the change according to the position of the hitting polo on the previous frame and the position of the hitting polo on the subsequent frame The progress path of the water polo hit by the accuracy is calculated to extract the progress path (S2) of the water polo.

Then, the water polo progression path S2 in the second comparison image P5 is compared with the water polo progression path S1 in the scoring path image P4, and the score failure cause information is output (step S270). The score failure cause information is provided to the user as an image by the display means 140, or is provided by voice.

In detail describing the output of the cause of failure in scoring, first, it is determined whether the progress path of the water polo which proceeds after hitting the first target ball in the second comparison image P5 deviates from the water polo progression path of the scoring path image P4. It judges (step S271). At this time, if it is determined that the progress path S2 of the water polo which proceeds after hitting the first target ball in the second comparison image P5 is out of the water polo progression path S1 of the scoring path image P4, this is a fault in our shop and thickness. It judges that it is and outputs it (step S272). And if the progress path (S2) of the hitting water polo to proceed after hitting the first object sphere did not deviate from the water polo progression path (S1) of the scoring path image (P4), the first target sphere in the second comparison image (P5) It is determined whether the angle of the hitting water polo hitting the rail 14 after hitting is out of the water polo propagation path (S1) of the scoring path image (P4) (step S274). If it is determined that the angle of the hitting water polo hit the rail 14 after hitting the first target ball is out of the water polo propagation path (S1) of the scoring path image (P4) it is determined to output a bad rotation amount ( Step S275). If the angle of the hitting water polo hitting the rail 14 after hitting the first target ball does not deviate from the water polo propagation path S1 of the scoring path image P4, the water polo hitting in the second comparative image P5 Whether it hits the first target sphere or hits the first target sphere and is guided along the water polo propagation path S1 of the scoring path image P4 is determined whether the second target sphere has not been hit (step S276). If the first object sphere or the second object sphere is not hit, the output is performed as a blow strength failure (step S277).
