A camera 200 that acquires images of the pool table 100 is disposed on the upper part of the billiard table 100. The camera 200 may only acquire an image of the billiard ball (B) in a stationary state, but in this embodiment, the movement of the cue stick (not shown) must be acquired, so the camera 200 that acquires the image is used. .

The beam projector 300 projects the guide paths (G1, G2) of the billiard ball (B) on the billiard table 100, and is generally used to project the guide paths (G1, G2) clearly under bright lighting. It is preferable that the beam projector 300 of greater than visual angle is installed.

The beam pointer 400 displays the cue pointer 410 on the cue ball (Bs) of the billiard ball (B), and a laser pointer can be used, and can also be used on the cue ball (Bs) close to the foot rail 110 of the billiard table (100). A plurality of beam pointers 400 can be installed between the foot rail 110 and the upper surface of the billiard table 100 so that the cue pointer 410 can be displayed.

The central processing unit 500 is connected to the camera 200, the beam projector 300, and the beam pointer 400, and moves the cue ball (Bs) according to the position of the billiard ball (B) sensed by the camera 200. (Generating the guide path (G1, G2), which is the movement path of the object ball (B1, B2) and cue ball (Bs) that collide with (Bs) and moves to the upper part of the billiard table (100) through the beam projector (300) Project it.

The guide paths (G1, G2) generated by the central processing unit 500 are generally implemented in various billiard simulation games, etc., and detailed descriptions thereof will be omitted.

The guidance paths (G1, G2) projected from the beam projector 300 have different colors or G1, Guidance route numbers such as G2 can be projected simultaneously.

Depending on the embodiment, the camera 200 installed on the top of the billiard table 200 may be used as the input unit 600 in addition to the input unit 600 consisting of a separate touch panel. In this case, when the learner indicates the guide path (G1, G2) projected on the billiard table 100 using a cue table, etc., the camera 200 can be configured to detect the selected guide path (G1) based on the acquired image. You can.

As shown in FIG. 2, when the learner selects one guide path (G1) among the plurality of guide paths (G1, G2) projected onto the billiard table 100, the central processing unit 500 As shown, only the selected guide path (G1) among the guide paths (G1, G2) projected by the beam projector 200 can be projected, and at this time, the beam pointer 400 is provided with a cue point ( 410) is projected to encourage the learner to hit the cue on the cue stand as the cue point 410.

Guidance on the movement of the cue stick can be displayed from the beam projector 300 to the upper surface of the billiard table 100, and can be displayed in various ways such as a slide bar, percentage, slide and percentage form like a typical billiard simulation game. You can.

The central processing unit 500 will be described in detail below with reference to FIG. 4, which is a block diagram of a billiard learning system according to another embodiment of the present invention.

The central processing unit 500 is connected to a batch database 510 that stores the arrangement data of the object balls (B1, B2) according to the position of the cue ball (Bs) among the billiard balls (B), and the cue ball (Bs) of the billiard ball (B) is connected to the central processing unit 500. ) When moving, the path generator 520 that generates the guide paths (G1, G2) is connected to the object balls (B1, B2).

As described above, the path generator 520 may generate in real time according to the arrangement of each cue ball (Bs) and object ball (B1, B2), but the arrangement of the billiard ball (B) stored in the arrangement database 510 Each route may be created in advance in the route creation unit 520 and stored in the batch database 510. When generating in advance in the path creation unit 520, there is no need to create the guide paths (G1, G2) through a separate calculation process, so the beam projector 300 can project the guide paths (G1, G2) more quickly. There is.

However, depending on the state of the billiard table 100, specifically the friction force of the screw paper through which the billiard ball B moves on the billiard table 100, and the repulsion force (elastic force) of the billiard ball B hitting the foot rail 110, the billiard ball The movement trajectory of the ball (B) becomes slightly different. Therefore, when using the billiard learning system so that the learner can move the billiard ball (B) along the guide path (G1, G2) according to the state of the billiard table (100), a correction step is configured before learning to place the basic billiard ball (B) , by hitting the cue ball (Bs) among the arranged billiard balls (B) with a cue, the movements of the cue ball (Bs) and the object balls (B1, B2) and the cue stick are tracked with the camera 200, and the cue ball according to the tracked movement is tracked. By sensing the movement of (Bs) and object balls (B1, B2), the friction force of the screw of the billiard table 100 and the elastic force of the foot rail 110 are calculated and reflected in the path generator 520 to generate the guide path (G1, G2) ) so that it can be created.

In order to learn billiards through the billiard learning system, the camera 200 senses the movement of the cue ball (Bs) and the object ball (B1, B2) after the learner moves the cue ball (Bs), and sends the cue ball (B1, B2) to the central processing unit 500. If the movements of Bs) and the object balls (B1, B2) are inconsistent with the guidance path selected by the learner, a judgment unit 530 that judges failure can be connected to guide the learner to success or failure.

Referring to FIG. 5, which is a side view and a top view of the beam pointer shown in FIGS. 1 and 4.

Since the number of beam pointers 400 installed on the foot rail 100 is inevitably limited, it is desirable to be able to move the cue pointer 410 displayed by the beam pointer 400. Therefore, the beam pointer 400 includes a beam generator 420 that generates a beam, a ball joint 430 disposed at the rear of the beam generator 420, and a beam generator 420 below the beam generator 420. A supporting sliding plate 440, a Z-axis actuator 450 that supports the bottom of the sliding plate 440 and raises and lowers the sliding plate 440, is disposed on the sliding plate 440, and uses a beam generator 420. It consists of an R-axis actuator 460 that rotates around the ball joint 430.

The ball joint 430 serves as the rotation center of the beam generator 420 and is rotatably connected to the inside of the beam point housing 412.

The sliding plate 440 is configured to allow the beam generator 420 to be seated and slide, and is formed in a plate shape. There is a Z-axis actuator on the lower and side surfaces of the beam generator 420 to move the beam generator 420. It consists of (450) and R-axis actuator (460).

It is preferable that an elastic body 470 is disposed on the upper surface of the beam generator 420 and the surface opposite to the R-axis actuator 460 to attenuate vibration generated when the beam generator 420 moves.

Referring to FIG. 4, a communication unit 600 may be connected to the central processing unit 500 to exchange data with another spatially separated billiard learning system.

This billiards learning system can transmit the location of each learner's billiard ball so that the learner can learn alone, but can play billiards with other learners in another space.

In other words, when the position of learner A's billiard ball is transmitted to learner B, learner B places the billiard ball on the billiard table at the location of the transmitted billiard ball, learner B moves the cue ball and moves the object ball, and learner B's The billiard learning system may transmit the location of learner B's billiard ball back to learner A so that learner A and learner B can play billiards in a space away from each other.

In addition, the success rate of learners for each batch data is stored in the batch data stored in the batch database 510, and stages can be set in order of high success rate.

In other words, in the case of batch data with a high success rate of learners, it is set to an easy stage, and in the case of batch data with a low success rate, it is set to a difficult stage. When batch data is stored in stages like this, the learner can input the learner's stage in the input unit 600 to induce learning in each stage of the learner.
