At this time, the position providing unit 210 can limit the user to select a skill level within the second grade from the current skill level.

Next, the position determination unit 220 determines that the position of the water polo and the two object positions taken from the camera installed on the upper side of the billiard table are the same as the position of the object on the billiard table, Or whether the position coincides with the position provided on the screen.

At this time, the position determination unit 220 may determine the color of the ball and the two object spheres, and determine whether each ball is positioned at the designated position.

Next, the receiver 230 generates a shot progress command signal when it coincides with the provided position, and receives a shot image of the billiard play of the current shot of the user.

Here, the shot progress command signal may provide an audio output through the display 400 to be interlocked or an image for allowing the display 400 to proceed to the shot. It can also be provided as light through a separate LED bulb. Such a shot advance command signal can be easily changed and designed by the user at a later time.

Next, the score determination unit 240 extracts the handwriting and the two target position changes in the current shot using the received shot image, and analyzes the extracted position change to determine whether or not the current shot is scored.

The score determination unit 240 may determine the color of each billiard ball in the photographed image, estimate whether the ball has moved according to predetermined rules through a change in the position of each ball, and determine whether the current shot is scored.

The rating approval unit 250 accumulates a result of determining whether or not to score a predetermined number of times, and if the number of times judged to be a score is greater than a predetermined threshold value, the rating authority of the user is approved as the selected rating.

 That is, the rating approval unit 250 can display the results of the determination of whether or not to score on the display 400 in order. If the number of times judged to be a score is smaller than the preset threshold value, And approve it as a previous grade.
