Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a billiard table and a billiard learning apparatus using the billiard table.

The present invention relates to a billiard table for judgment and a billiard learning apparatus using the billiard table, and more particularly to a billiard table capable of detecting the impact of a billiard ball detected by a cushion of a billiard table, .

A billiard is a game in which a billiard ball is placed on a billiard table, and a billiard ball is hit by a cue ball to block the game according to rules. There are four types of billiards, a four-ball game, a three-ball game such as a cushion, and a pocket game such as Eight Ball and Nine Ball. Of these, four or three cushions are often played in Korea.

Among them, a thrive cushion is a ball to be matched to both the first and second ball, but the ball must be hit at least three times before the second ball is hit. In addition, there is a need for a method and apparatus for judging the success or failure of the three-cushion game, since the rule of the four-cushion game can be won by winning at least one time.

Patent Document 1 discloses a method of determining success or failure of a shot using a conventional moving picture. A method of determining the success of a shot using a conventional moving image is as follows. First, a partial motion image for one shot is generated based on whether the billiard ball is moving. Then, the first frame of the partial motion image is compared to determine whether the color of the billiard ball (If the shot is successful, the ball will be retained, and if the shot fails, the ball will change).

However, this conventional determination method is an indirect method of judging whether a shot is successful depending on whether the bill is to be changed or not, instead of judging whether the ball is hit by a billiard ball or a billiard ball or a billiard ball and a cushion. In the case of failing and failing a shot as a success, such a mistake is directly reflected in the success or failure of the shot, so that the accuracy of the judgment is somewhat inferior. Also, there is a problem that it is difficult to know the success of a shot because it is difficult to judge how a billiard ball cushion is hit in a beginner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a billiard table for judgment and billiard learning apparatus using the same according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a configuration diagram of a billiard table for judgment according to the present invention. The billiard table for judgment according to the present invention includes a billiard paper 12, a cushion 14 formed on the outer periphery of the billiard paper 12, The billet table main body 10 constituted by the billet table 10 and the support table 16 for supporting the billet 14 and the collision sensor 20 disposed at the outer periphery of the cushion 14 and the collision sensor 20, And a reset button 50 that is configured to include the control board 30 and is exposed to the support 16.

Since the billiard table main body 10 is the same as a general billiard table, detailed description is omitted.

The impact sensor 20 is disposed on the outer periphery of the cushion 14 and is a component for sensing the impact when the billiard ball is reflected on the cushion 14 and converting it into an electric signal. Since it is only necessary to detect whether or not the billiard ball of the impact sensor 20 collides with the cushion 14, it may be a single sensor that surrounds the cushion 14. However, It is preferable that one of the cushions 14 is disposed on one side. This is because, when two or more billiard balls are moved and reflected to the collision sensor 20 at the same time when a shot occurs, an error such as the collision sensor 20 detecting a collision may occur.

More preferably, a plurality of impact sensors 20 may be disposed on one side of the cushion 14 because when the plurality of impact sensors 20 are disposed on one side of the cushion 14, ), And it is easy to determine whether or not the shot is successful in the billiard learning apparatus to be described later. It is preferable that the density of the impact sensor 20 increases (that is, the number of the impact sensors 20 per unit length of the cushion 14 increases) as it approaches the corner of the cushion 14. This is because the billiard ball is often reflected to the corner of the cushion 14 in a billiard game such as a thrive cushion and the more the impact sensor 20 is located on the corner of the cushion 14, to be.

It is preferable that the impact sensor 20 can detect the impact while being spaced apart from the cushion 14 by a predetermined distance in order to eliminate the influence of the impact force of the cushion 14 Do. The impact sensor 20 may be a laser displacement sensor or the like. The sensor type can be freely selected within a range that does not greatly affect the repulsive force of the cushion 14.

The control board 30 processes the electric signal outputted when the collision sensor 20 detects a collision into judgment data of a predetermined data format and transmits it to an external device or processes it by itself. The determination data may include the position of the collision sensor 20 in which the collision is detected, the collision time, the magnitude of the impact, and the like, and the configuration of the specific data for determination may vary depending on what type of data is requested by the external device. In this case, the external device may be a main server or the like, which is a component of the billiard learning apparatus according to the present invention, and the fact that the external device is processed by itself means that the judgment may be made in the billiard table itself according to the present invention, The board 30 performs a judgment algorithm.

The indicator 40 is a component indicating that there is a collision when a collision is detected in the collision sensor 20, and a lamp, an LED, or the like may be used. In FIG. 1, two LED indicators are shown as an example of the display device 40. In this case, since each LED indicator can display one bit of information, a total of four states can be displayed. It is of course also possible to use a 7-segment LED or LED array as the indicator 40 to display more information. When there is the indicator 40, the lighting control of the indicator 40 is performed by the control board 30.

The reset button 50 is a button for putting the indicator 40 in a reset state, for example, an unlit state, in which the collision caused by one shot before pressing the shot is not affected by the data generated according to the shot . If there is no reset button 50, collisions generated by two or more shots can be accumulated and counted. The function of the reset button 50 may be performed by control of the control board 30 or an external device but is preferably exposed to the outside of the billiard table for judgment according to the present invention such as the surface of the support table 16 for convenience Do.

Fig. 2 is a state view of the billiard table for judgment according to the present invention, and shows an example of a three-cushion game. FIG. 2 (a) shows a case of outer turning, in which a yellow ball Y as a first objective is hit by hitting a white ball W as a hand, and a white ball W turns rightward And the red ball (R), which is the second objective, is aligned. In this case, among the two LEDs of the indicator 40 connected to the collision sensor 20 where the white ball W collides, the LED adjacent to the cushion (hereinafter referred to as the " inner LED ") is turned on. Thus, the user can intuitively know at which point of the cushion 14 the white ball W has hit the triple cushion.

Here, it can be seen that the lighting of the LED adjacent to the cushion 14 means one collision. Since there are two LEDs, it is possible to display the same collision sensor 20 even if there are two or more collisions. FIG. 2 (b) shows a double rail shot, in which the yellow ball Y, which is a first object, is struck by hitting the white ball W, which is a hand, and the left long and short cushions 14, (14), and then reflected on the left long side cushion (14) to align the red target (R) as the second target. In this case, the white ball W collides with the same impact sensor 20 twice. The two collisions can be displayed by lighting all the two LEDs.

In this way, it is possible to display three or more collisions by lighting the LED (hereinafter referred to as "outside LED") far from the cushion among the two LEDs. The reason why there is no need to distinguish three or more collisions on the same collision sensor 20 is that it is not necessary to accurately count three or more collisions in a game such as a thrill cushion. Therefore, the display device 40 may be composed of two LED indicators so as to display the collision of one time, two times, and three times.

In FIG. 2, it can be seen that LED lighting may occur due to the collision of the yellow ball Y, which is the first object, and the collision outside the water balloon should not be counted, which will be described later.

3 is a state transition diagram of the indicator lighting control performed by the control board. In case of reset, all LEDs are turned off, and when a collision is detected in a specific collision sensor 20, the inner LED indicates that both the inner and outer LEDs are illuminated when collision is detected again, The number of collision of the billiard ball can be displayed.

Next, a billiard learning apparatus according to the present invention will be described.

FIG. 4 is a configuration diagram of a billiard learning apparatus according to the present invention. The billiard learning apparatus according to the present invention includes a billiard base 100, a camera 200, a terminal device 300, a wired / wireless network device 400 And a server 500. As shown in FIG.

The camera 200 is installed on the billiard table 100 according to the present invention to photograph the movement of the billiard ball according to the shot in the billiard table 100 according to the present invention, (300).

The terminal device 300 includes an input means, a storage means, and a display means for receiving an image photographed from the camera 200 and allowing the user to reproduce, edit, or transmit the image to the mobile terminal or the server 500 Element.

The wired / wireless network device 400 connects the billiard table 100, the camera 200, and the terminal device 300 to form a local network, thereby enabling data transmission between the components. And can be connected to the Internet to access the server 500.

The server 500 includes a membership management module, a billiard learning content storage module, and an authentication module.

The membership management module is a component for storing and updating membership registration, withdrawal, billiard learning content download, authentication level, and the like, and blocks downloading, learning, and authentication of billiard learning content of non-members.

The billiard learning content storage module stores billiard learning contents such as video for lecture and provides billiard learning contents when requested by the terminal device 300. [

The authentication module is a component for judging the certification level of the member. If the test content is stored, and the member downloads the test content and submits the test result video, the authentication module determines success according to the determination algorithm. The test contents include the position of the billiard ball and the contents of the test contents in which the thrill cushion can be tested, such as turning, outward, before, and hanging, and can be confirmed by the member at the terminal device 300.

The authentication module also determines whether the thrushing has been successful by the judgment data transmitted from the control board 30 of the billiard base 100 according to the present invention according to a predetermined judgment algorithm. The determination result is accumulated and used to determine an authentication level according to a set criterion such as the success or failure of the trial content group, the number of successes to the trial number, and the like, and is transmitted to the terminal device 300 in real time, .

Next, a determination algorithm of the test content will be described. In the case of a three-cushion game, only when the first object ball and the second object ball are both matched with the ball and the ball is hit at least three times and then the second ball is hit, It is judged whether the target ball is hit all the way, whether the ball is hit at least 3 times and then hit the second goal ball.

5 is a flowchart of a judgment algorithm for judging whether or not a water polo matches both the first object sphere and the second object sphere. When there is a collision between the ball and the target ball, the position of the ball is changed. In this case, it is necessary to distinguish between the first and second objects. In the case of a thrive cushion game, the object is white (or yellow), and the object is red and yellow (or white). . That is, as shown in FIG. 5, by comparing the frames I (t-1, 0) to I (t, Fmax) from the time t-1 to t to see whether the first object ball CB1 collided with the ball, This is the same for the second object CB2. At this time, it is necessary to exclude the collision between the first object CB1 and the second object CB2 by excluding the collision between the yellow ball and the red ball when the ball is white. For reference, the ball can judge the first moving ball as a water polo by comparing I (t-1, 0) with the next frame.

Next, it is necessary to judge whether or not the second object ball is hit after at least three cushions have been hit. This means that the number of collisions in the judgment data transmitted from the control board 30 of the judging bill base 100 according to the present invention Counting, and judging whether or not the cue ball and the second target ball have collided after three collisions. For example, if the collision is two times, it can be judged as unconditionally failure. Therefore, it is judged whether or not the cue ball is matched to the first object and the second object, or whether the cue ball has hit the second object after cushioning at least three times no need. Therefore, it is possible to reduce the amount of calculation by judging whether or not the cue ball has hit the second target ball after cushioning at least three times before the ball catches the first target ball and the second target ball.

FIG. 6 is a diagram illustrating an example in which collision occurs three times, in which image frames are arranged on a time axis. The collision at t3 should be counted because it is due to the yellow ball (Y) which is the first objective, and it is considered that the collision at t3 occurs more than three times. However, since it is impossible to judge such a situation only by the collision frequency, it is necessary to consider whether or not the watercourse is adjacent to the collision sensor 20 at the time of collision. At this time, it is also possible to use the color of the billiard ball. If there is a white ball in the vicinity of the collision sensor 20 at the time of t1 and t2 when the cue ball is white, it can be known that there is a normal cushion collision due to the water balloon. The higher the density of the impact sensor, the easier it is to locate the billiard ball). In FIG. 6, since there is a yellow ball near the collision sensor 20 where the collision occurred at time t3, one collision can be excluded from the count. Here, the vicinity of the collision sensor 20 can be defined as a rectangular region (a hatched portion in FIG. 6) having the width of the impact sensor 20 along the longitudinal direction of the cushion 14 and the diameter of the billiard ball, .

In the case where collision by the handball occurs three times, it is only necessary to judge whether or not the handball has collided with the second target ball after that, which is the same as the judgment algorithm for judging whether or not the ball catches the first target ball and the second ball Do.

Fig. 7 is an exemplary diagram showing an embodiment in which all of the determination algorithms are applied, using Fig. 2 (a) as an example. At the time of t1, t2, t3 and t4, there was a collision between the billiard ball and the cushion, and at the time of t1, t2 and t4, there was a normal cushion collision due to the ball. It can be seen that the thigh cushion succeeded because the crown W hit the second objective R at tcb2 after three collisions of the cushion by the cue ball W. [

FIG. 8 is an exemplary view of an instruction screen displayed on the terminal device, and FIG. 9 is an exemplary view of a test and authentication screen. Each screen has a lecture or a test list. You can select the content, and there is a menu that allows you to select the content, listen to the explanation, switch the practice video, and start and end the recording.
