Description

The present invention relates to systems and methods for tracking and verifying the position of golf balls.

During a golf competition, when a beginner hits a long hit with a driver or wood on the field, the ball that is swung by many beginners does not fly in the front direction, which is the target point, but flies outside the designated course. OB (Out of Bounds) is often hit.

However, the OB area, that is, the no-play area, has a longer lawn or is thicker with weeds than the play area, so it is very difficult to find a dropped ball there.

Therefore, the game will be delayed by the amount of time it takes to find the golf ball, which will hinder the progress of the next team's game, and if the ball cannot be found, the loss of the ball will cause economic loss. Occur.

6 and 8 are flowcharts illustrating a method for tracking and identifying the position of a golf ball according to one embodiment of the present invention, and FIG. 7 is a detailed flowchart of S730 illustrated in FIG.

Referring to FIG. 6, the method for tracking and confirming the position of a golf ball (S700) according to an embodiment of the present invention first reads and transmits the RFID tag information of the golf ball used for rounding from the wearable terminal 200. Then, the current position is set as the golf rounding start point (S710).

After that, the RFID tag information of the golf ball is registered with the location tracking server. A repeater located at the starting point of golf recognizes the RFID signal of the golf ball.

When the user hits the corresponding golf ball, a plurality of repeaters installed in the corresponding hole receive the RFID signal of the golf ball and transmit the RFID received signal to the location tracking server 300 (S720). Here, the RFID reception signal may be information including signal strength and reception angle.

After that, the position tracking server 300 determines the first landing point of the golf ball and the golf ball from the first landing point based on the position coordinates of the plurality of stationary repeaters that transmitted the RFID reception signal and the angle and strength of the RFID reception signal. After calculating the position information of the golf ball including the movement path of the ball and the final position information (S730), the golf ball map including the position information of the hit golf ball is relayed by a mobile radio adjacent to the wearable terminal. Send to the terminal (S740).

It can also include a process of calculating the movement path of the golf ball, the current position coordinates, the flight distance, the distance remaining to the golf ball, the distance between the golf ball and the hole cup, and the like.

In addition, in the above step S730, when the signal of the golf ball being recognized exceeds the recognition range of the repeater and changes to the unrecognizable state, the direction in which the golf ball moves out of the range of the repeater is determined based on the final information collected. It can further include calculating distances to derive virtual predicted coordinates and sending real-time GPS coordinates (distance between mobile device and golf ball, distance between mobile device and hole cup, etc.).

More specifically, the step S730 is performed by the received signal amplifying and filtering unit 361 to remove the signal with the highest magnitude among the receiving angles and receiving strengths of the received signals of the RFID signals provided from the plurality of repeaters. After the remaining signal is filtered and the received signal that has passed through is amplified (S731), the position coordinate calculator 362 calculates the two-dimensional plane coordinates of the received signal that has passed through the received signal amplification and filtering unit in units set in advance. (S732), the two-dimensional plane coordinates calculated over time by the position coordinate calculator 362 and angle information at which the signal is received are continuously provided (S733), and the moving direction and distance calculator 363 continuously provides the position coordinates Based on the two-dimensional plane coordinates continuously calculated along the time calculated by the calculator 362 and the angle information at which the signal is received, the traveling direction and movement distance of the golf ball are calculated (S734).

On the other hand, when the golf ball recognized by the movement direction and distance calculation unit 363 leaves the relay area or the RFID reception signal is not sent, the golf ball is moved based on the learning information of the golf ball departure route learned by the learning unit described later. A process of predicting (S735) the expected exit path and direction may be included.

After that, when the golf ball map including the position information of the golf ball is transmitted from the location tracking server 300 to the mobile wireless relay terminal adjacent to the wearable terminal (S740), the map showing the coordinates of the golf ball is displayed on the wearable terminal. is activated (S750).

Thus, utilizing a system and method for tracking and determining golf ball position in accordance with one embodiment of the present invention, the present invention can prevent a user's hit ball from going as intended by the user and the golf ball. There is an advantage that the position of the golf ball can be accurately detected when it enters a rough area, an OB area, or a hazard area.

In addition, the present invention has the advantage that an inexpensive RFID chip can be embedded in a golf ball and a golf ball detection device to facilitate ball identification and user identification through the ID embedded in the RFID chip.

In addition, the golf cart wirelessly detects the distance between itself and the golf ball and the distance between itself and the golf ball detection device through the Bluetooth(R) system between the golf cart and the user's portable golf ball detection device. It also has the advantage of being able to more accurately determine the position of the golf ball by triangulation by delivering it to a portable device.

In addition, the present invention has the advantage that the distance and direction to the golf ball can be more accurately displayed on the basis of the user through the display means of the golf ball detection device.
