DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a detailed block diagram of a golf simulation apparatus according to an embodiment of the present invention.

As shown, the golf simulation apparatus 100 according to an embodiment of the present invention is a club information receiver 110, trajectory calculation unit 120, information display unit 130, information sensing unit 140, club information management unit 150, a golf club identification unit 170, and a database 160.

Club information receiving unit 110 receives the information of the golf club selected by the user. The user may receive information of a golf club directly input through various input devices (not shown) such as a keyboard or a mouse. In addition, it is possible to receive the information of the golf club identified through the golf club identification unit 170 to be described later. The received information about the golf club may be transmitted to the trajectory calculation unit 120, club information management unit 150 or database 160.

The trajectory calculator 120 may read information about the average head speed and the loft angle of the golf club received from the club information receiver 110 from the database 160 to be described later. Head speed refers to the speed of the head of the club at the moment of impact of the golf ball and head when downswinging the golf club. This head speed may vary from user to user. In addition, the head speed for each golf club may be different depending on the length of each golf club and the weight difference of the head. However, each user's head speed for a particular club will remain within a certain range. In addition, the average head speed is the average value of the head speed values for each club recorded whenever the user hits the golf ball. The information sensing unit 140 to be described later senses the head speed of the golf club at the time of hitting the golf ball, and the club information management unit 150 accumulates and stores the head speed of the sensed golf club for each golf club. The average head speed may be calculated by averaging the accumulated head speed for each golf club.

In addition, a loft angle means the inclination of the part (face) which a ball hits in the head of a golf club, and each club has a unique value.

In addition, the trajectory calculation unit 120 may predict the trajectory of the golf ball based on the read average head speed, the loft angle, and location information and height information for each location on the course map of the golf course stored in the database 160. have. The trajectory calculator 120 may calculate an expected back spin of the golf ball based on the average head speed and the loft angle information of the golf club selected by the user. Backspin means revolution per minute (rpm) immediately after the impact of the golf ball. For example, the backspin may be 1,500, 1,750, 2,000, 2,250-13,750 rpm. In addition, the trajectory calculator 120 may predict the trajectory of the golf ball based on the calculated backspin information, the average head speed and the loft angle information of the golf club. Furthermore, the trajectory calculator 120 may predict the trajectory of the golf ball by considering not only the location information and the distance information of each location on the golf course course map, but also the height information, and predict the point where the golf ball is actually landed.

Each position on the course map of the golf course is actually not constant in height, and may have a height difference from the hitting point of the golf ball. That is, the trajectory of the golf ball when the height difference occurs between the hitting point and the destination should be different from the trajectory when the two points are assumed to be at the same height.

2 to 4, the trajectory of the golf ball when the height difference occurs between the hitting point and the destination will be described in detail.

FIG. 2 is a view showing an adjustment distance when the height of the destination and the hitting point is the same, FIG. 3 is a view showing an adjustment distance when the destination is below the hitting point, and FIG. 4 is a point where the destination is above the hitting point. It is a figure which shows the adjustment distance in case of. The adjustment distance means a distance between a point where the predicted trajectory of the golf ball is equal to the height of the hitting point and the hitting point.

Referring to FIGS. 2 to 4, the adjustment distance will be described. As shown in FIG. 2, when the hitting point and the destination are horizontal, the distance from the hitting point to the destination is equal to the adjusting distance. However, as shown in Fig. 3, when the height of the destination is lower than the hitting point, the adjustment distance is shorter than the GPS distance, that is, the horizontal distance seen from above. Further, as shown in Fig. 4, when the height of the destination is higher than the hitting point, the adjustment distance is longer than the GPS distance. Thus, when the location of the destination is several meters above or below the point of impact, it is longer than the point of impact and the destination for the upper destination, and the point of attack and the destination for the lower destination. Will have to send the golf ball shorter than when it is at the same height. In FIG. 2 to FIG. 4, the green distance means a straight distance from a tee box to a green. Alternatively, it may mean a straight distance from the fairway to the green. This includes the case from the tee box to the green that is inclined up or down.

As such, the trajectory calculation unit 120 predicts the trajectory of the golf ball by considering the height information for each location on the course map, so that the user thinks that the user will actually send a certain distance when the height of the destination is different from the hitting point. And hitting the golf ball will know if you can send the golf ball close to the destination.

Returning to FIG. 1 again, when the user strikes the golf ball using any one of the golf clubs, the trajectory calculation unit 120 positions the head speed of the golf club, the loft angle of the golf club, and the position of each position on the course map. The trajectory of the hit golf ball can be calculated based on the information and the height information.

A detailed method of predicting the trajectory of the golf ball by the trajectory calculator 120 will be described later.

The information display unit 130 may display the trajectory of the golf ball predicted by the trajectory calculating unit 120 through various output devices such as a screen golf screen. For example, before the user hits the golf ball, the information display unit 130 predicts golf based on the average head speed, the loft angle, the location information for each location on the course map, and the height information before the golf ball is hit by the user. The trajectory of the ball can be displayed. In addition, the information display unit 130 may display the distance from the predicted trajectory of the golf ball to the expected landing point of the golf ball and the height information of the landing point.

In addition, when the user hits the golf ball using any one of the golf clubs, the information display unit 130 is based on the head speed of the golf club, the loft angle of the golf club, the location information for each location on the course map and the height information. The trajectory of the golf ball calculated based on this can be displayed.

The information sensing unit 140 may sense the head speed of the golf club when the golf ball is hit. In addition, the information sensing unit 140 may sense the speed of the golf ball when the golf ball is hit. The speed of the golf ball is the speed at which the golf ball leaves the club after it is hit. In addition, the information sensing unit 140 may sense a launch angle of the golf ball. Lunch angle means the angle to the ground when the golf ball leaves the club.

The club information manager 150 may accumulate and store the head speed of the golf club sensed by the information sensing unit 140 in the database 160 to be described later in association with the golf club information.

In addition, the club information management unit 150 may calculate the head speed of the golf club using the speed of the golf ball sensed by the information sensing unit 140. The club information management unit 150 may calculate the head speed of the golf club from the speed of the golf ball using Equation 1 below.

[Equation 1]

Ball Speed = (Head Speed * (1 + Golf Club Repulsion) / (1 + Golf Ball Mass / Golf Club Mass)) * Cos [(Loft Angle * Pi / 180)-(6.5 * Pi / 180) ]

In Equation 1, Pi is 3.14.

In addition, the club information manager 150 may accumulate and store the calculated head speed of the golf club in the database 160 to be described later in association with the golf club information.

The golf club identification unit 170 may identify a golf club selected by the user. For example, the golf club identification unit 170 may identify the golf club based on the identification information of the golf club recorded on the barcode or RFID tag attached to the golf club. That is, the golf club identification unit 170 may check whether the selected golf club is iron, wood, putter. The golf club information thus identified is transmitted to the club information receiver 110.

The database 160 may store a course map of a golf course, location information and height information for each location on the course map, average head speed for each golf club of the user, and loft angle information for each golf club. In addition, when the user hits the golf ball using any one golf club, the database 160 may store and accumulate the head speed of the golf club or the speed of the golf ball in association with the existing information of the golf club. have.

As described above, according to the golf simulation apparatus 100 according to an embodiment of the present invention, the trajectory of the golf ball is estimated in consideration of not only the distance information but also the height information of each position on the golf course course map, thereby providing a more accurate trajectory to the user. Prediction information can be provided.

5 is a view for explaining the prediction of the golf ball trajectory by the golf simulation apparatus according to an embodiment of the present invention.

In Fig. 5, z is an axis perpendicular to the ground (gravity acceleration direction), and α is a launch angle. The launch angle is determined by the loft angle. The trajectory calculation unit 120 may calculate a launch angle from the loft angle using Equation 2 below.

[Equation 2]

Launch angle = -0.0071 * Loft angle ^ 2 + 0.96 * Loft angle

In order to predict the trajectory of the golf ball, the trajectory calculating unit 120 first calculates an expected backspin of the golf ball based on the head speed and the loft angle information of the golf club, and then calculates the golf ball based on the calculated backspin. The dragging coefficient and the lifting coefficient of can be calculated.

The trajectory calculator 120 may calculate the backspin of the golf ball by Equation 3 below.

&Quot; (3) "

Spin (rpm) = 60 * [160 * Head Speed (km / h) * Sin [Loft Angle * Pi / 180]]

In Equation 3, Pi is 3.14.

The trajectory calculator 120 may predict the trajectory of the golf ball based on the acceleration in the X-axis, Y-axis, and Z-axis directions of the golf ball determined based on the calculated delay coefficient and the rising coefficient.

The trajectory calculator 120 may determine accelerations in the X-axis, Y-axis, and Z-axis directions of the golf ball by Equations 4 to 6 below.
