Best Mode for Carrying Out the Invention

[0017] A specific structural or functional description of an embodiment according to the concept of the present invention disclosed in this specification or application is merely an exemplification for explaining an embodiment according to the concept of the present invention. An embodiment according to the concept of the present invention may be implemented in various forms and should not be construed as being limited to the embodiment described in this specification or application.

[0018] Hereinafter, in order to explain in detail to such an extent that those having ordinary knowledge in the technical field to which the present invention pertains can implement the technical idea of the present invention, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0019] FIG. 1 is a diagram for explaining a padding assistance system according to an embodiment of the present invention.

[0020] Referring to FIG. 1, the padding assistance system 1000 may include a terminal 100, a server 200, a database (DB) 300, and a padding assistance device 400. The padding assistance system 1000 is based on a network, and the network means a connection structure in which each node such as the terminal 100, the server 200, and the padding assistance device 400 can exchange information with each other.

[0021] The terminal 100 may be mounted on a golf cart. The terminal 100 may be a tablet PC, but is not limited thereto, and may be implemented as various forms of electronic devices such as a smartphone, a laptop computer, and an in-vehicle infotainment system.

[0022] In one embodiment, terminal 100 is controlled by input from the player using terminal 100 and can communicate with server 200 using wireless communication. Since terminal 100 is mounted on a golf cart, it can provide an environment where players can freely use terminal 100 while playing golf. Terminal 100 can communicate data with server 200 using a wireless communication system.

[0023] The golf cart may be a single-seater cart that each player participating in the round can drive themselves, or a multi-seater cart that can accommodate two or more people. In one embodiment, unlike conventional six-seater golf carts that only move along pre-set cart paths, the golf cart can enter all areas of the course, including the fairway, except for no-go zones, and move to where the player's ball is located. Therefore, the distance that players must walk can be minimized, and the time spent playing golf can be shortened. In one embodiment, the no-go zones may be the rough, bunkers, penalty areas, and greens (including the apron). Here, penalty areas may be areas where shots cannot be taken, such as lakes, rivers, and drainage channels.

[0024] Once a player's ball lands on the green, they can use a golf cart to travel to the entrance of the green. On the green, players can use the putting assistance device 400 to receive putting strategy information.

[0025] Terminal 100 can provide various data related to golf play to server 200 and receive putting strategy information, which is data for putting assistance, from server 200. Based on the data received from server 200, terminal 100 can provide putting strategy information to the player. In one embodiment, terminal 100 can extract voice guidance information from the putting strategy information received from server 200, or generate voice guidance information based on the putting strategy information. Terminal 100 can provide the voice guidance information to the putting assistance device 400.

[0026] Terminal 100 can communicate data with the putting assist device 400. In one embodiment, since the terminal 100 and the putting assist device 400 can be kept at a relatively close distance of within tens of meters, data communication can be performed using short-range wireless communication methods such as Bluetooth, Wi-Fi, ZigBee, and ultra-wideband (UWB) communication.

[0027] The putting assist device 400 may be attached to the player's golf club. In one embodiment, the putting assist device 400 may be located inside the grip of the player's golf club. For example, the putting assist device 400 may be in the form of a hardware device built into a shell (housing) wrapped with a grip cushion. In one embodiment, the putting assist device 400 may be attached by being twisted and inserted onto the shaft of the club. In one embodiment, the shell (housing) in which the putting assist device 400 is built may be made of reinforced plastic.

[0028] The structure and operation of the putting assist device 400 will be explained in more detail in the descriptions of Figures 2 to 4 below.

[0029] Server 200 may be located at a specific location within the golf course or at a remote location outside the golf course. Server 200 can communicate with terminal 100 using a wireless communication system. Wireless communication systems used by terminal 100 and server 200 include, but are not limited to, 3GPP (3rd Generation Partnership Project) (registered trademark) networks, LTE (Long Term Evolution) networks, 5G (5th Generation Mobile Tele-communication), WiMAX (World Interoperability for Microwave Access) networks, the Internet, WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth networks, satellite broadcasting networks, analog broadcasting networks, DMB (Digital Multimedia Broadcasting) networks, and Wi-Fi.

[0030] The server 200 may include an AI computing module 210 and a communication module 220.

[0031] The AI ​​computing module 210 can generate putting strategy information using data stored in the database 300 and data provided from the terminal 100. The AI ​​computing module 210 can generate putting strategy information to provide to players using various algorithms such as deep learning, machine learning, and neural network circuits that utilize big data. The AI ​​computing module 210 can provide putting strategy information to the terminal 100 using the communication module 220.

[0032] The communication module 220 can communicate data with the terminal 100 and the database 300.

[0033] The database 300 can store player record information. Player record information may include the average number of putts learned from the player's past playing results, putting distance information, putting ball trajectory information, etc. In one embodiment, the information included in the player record information may further include information on temperature, humidity, and type of grass.

[0034] In one embodiment, the database 300 can store information about a golf course. This information may include topographical information about the golf course, the standard number of strokes for each hole, the slope of the green, the pin position for each hole, and information about the turf of the golf course. In one embodiment, the database 300 can store data received from the server 200 or transmit data to the server 200. For example, the database 300 may be embodied in a non-volatile memory device such as an SSD (Solid State Drive) for storing data.

[0035] Figure 2 is a diagram illustrating one embodiment of the putting assist device 400 shown in Figure 1.

[0036] Referring to Figure 2, a golf club generally includes a head, shaft, and grip. The head is the part that directly strikes the ball and can have various shapes and materials depending on the type of club. The shaft is the part that connects the grip and the head and can have various materials and strengths. The grip is the part that the player directly holds in their hand, and the player can perform a golf swing by swinging the club while holding the grip. The grip is generally inserted into the shaft and can have various weights and shapes depending on the type of club. In particular, putters, which are clubs used for putting, can use grips that are relatively longer and thicker than those of other clubs.

[0037] In one embodiment, the putting assist device 400 can be located inside the grip.

[0038] The putting assist device 400 may include a pressure sensor, GPS antenna, precision GPS module (RTK module), MCU (Micro Controller Unit), communication module, charging module, rechargeable battery, charging terminal, speaker, etc.

[0039] The pressure sensor can sense the pressure applied by the player's hand gripping the grip, which is input through the surface of the grip. The pressure sensor can convert the sensed pressure into an electrical signal and provide it to the MCU (Micro Controller Unit).

[0040] In various embodiments, although not shown in the drawings, the putting assist device 400 may further include a button switch for requesting putting strategy information. Using the button switch, the player can provide a control signal to the MCU for requesting putting strategy information by pressing the button switch at the location of the ball.

[0041] A GPS (Global Positioning System) antenna can be an antenna that receives signals transmitted from GPS satellites. An MCU (Micro Controller Unit) can calculate the position information of the putting assist device 400 based on the signals transmitted from GPS satellites.

[0042] A precision GPS module (RTK module) is a GPS module that incorporates the concept of real-time mobile positioning. It may be a module that uses a correction value for the carrier phase of a base station (GPS Base) with precise position information to obtain accurate positioning results in real time at a mobile station (Rover). Existing GPS modules can suffer from various errors due to the ionosphere, atmosphere, satellite errors, etc., but precision GPS modules (RTK modules) have the advantage of compensating for the decrease in positional accuracy caused by signal distortion and delay that occurs when GPS satellite signals pass through the ionosphere, thereby reducing errors to 1-2 cm.

[0043] In one embodiment of the present invention, the putting assist device 400 is attached to the grip of the putter, and the player putts at the point where the ball is located. Therefore, the position in which the player takes their address posture to putt can be considered the most accurate position of the ball. Accordingly, by using the precision GPS module (RTK module) of the putting assist device 400, it is possible to obtain putting strategy information at the accurate ball position in real time.

[0044] The MCU (Micro Controller Unit) consists of a CPU core, memory, and programmable input / output, and can control the operation of the pressure sensor, GPS antenna, precision GPS module (RTK module), communication module, charging module, rechargeable battery, charging terminal, and speaker included in the putting assist device 400.

[0045] The communication module can perform short-range communication between the putting assistance device 400 and the terminal 100, as described with reference to Figure 1. The communication module can provide location information acquired by the precision GPS module (RTK module) to the terminal 100 and receive voice guidance information for putting strategy from the terminal 100.

[0046] The charging module may be a module that provides the function of charging a rechargeable battery. The rechargeable battery can provide the power necessary to drive the putting assist device. In one embodiment, the charging terminal may be a wired or wireless charging terminal for charging the putting assist device 400. In various embodiments, the charging module may also provide the function of wirelessly charging a club when it is placed on a club stand provided on a golf cart.

[0047] The speaker can provide players with audio information on putting strategies to help them conquer the hole. For example, the speaker can output audio guidance information for putting strategies, specifically received from terminal 100.

[0048] Figure 2 is merely an example of the various components included in the putting assist device 400, and does not limit the arrangement or function of the components included in the putting assist device 400.

[0049] For example, the putting assist device 400 can detect the player's address posture and movement by utilizing an accelerometer and gyroscope in addition to a pressure sensor. Furthermore, more precise posture analysis may be possible by using various sensors. In one embodiment, the accelerometer can measure the player's swing speed and direction to provide more accurate putting information.

[0050] Figure 3 illustrates another embodiment of the putting assist device shown in Figure 2.

[0051] The difference between one embodiment in Figure 3 and one embodiment in Figure 2 can be the form of the GPS antenna. The GPS antenna may be a modular component mounted in the shell inside the grip, as shown in Figure 2, or it may be arranged inside the grip in a coiled form. Also, the positions of the speaker, charging terminal, rechargeable battery, etc., may be arranged in a different form from the embodiment in Figure 2, as shown in Figure 3.

[0052] Figure 4 is a diagram illustrating the operation of the putting assist device.

[0053] Referring to Figure 4, the putting assist device 400 may include an input unit 410, a communication unit 420, an output unit 430, and a control unit 440.

[0054] The input unit 410 can receive input requesting putting strategy information (voice guidance information). The input unit may be implemented in the form of a button switch. The player can request putting strategy information (voice guidance information) by pressing the button switch. In response to the player pressing the button switch, the input unit 410 can provide a control signal to the control unit requesting putting strategy information (voice guidance information).

[0055] In various embodiments, the input unit 410 may be represented by a pressure sensor that senses the pressure on the grip surface. For example, the input unit 410 can sense the pressure applied by a player gripping the grip via the grip surface. In one embodiment, the input unit 410 may be represented by a pressure sensor described with reference to Figures 2 and 3. The input unit 410 can sense the gripping pressure and transmit it to the control unit 440.

[0056] The control unit 440 can control the operation of the putting assist device 400. The control unit 440 may be an MCU as described with reference to Figures 2 and 3.

[0057] The control unit 440 receives a control signal from the input unit 410 requesting putting strategy information (voice guidance information), and controls the communication unit 420 according to the received control signal to acquire ball position information and provide the acquired ball position information to the terminal 100.

[0058] In one embodiment, when the input unit 410 is embodied by a pressure sensor, the control unit 440 can determine whether or not the player has assumed an addressing position based on the pressure signal received from the input unit 410. When the control unit 440 determines that the player has assumed an addressing position, it can control the communication unit 420 to calculate the ball's position information, which is the current position information. For example, the control unit 440 can determine that the player has assumed an addressing position if the player's pressure signal falls within a preset range. The control unit 440 can determine that the player has not assumed an addressing position if the player's pressure signal falls outside the preset range.

[0059] In one embodiment, the communication unit 420 may include a GPS module, a precision GPS module (RTK module), and a communication module, as described with reference to Figures 2 and 3. The control unit 440 can control the GPS module or precision GPS module (RTK module) of the communication unit 420 to acquire location information and to provide the acquired location information, which is the location information of the ball, to the terminal 100.

[0060] Terminal 100 can provide the server 200 with ball position information and player information received via the communication unit 420. The server 200 can generate putting strategy information based on the received information and provide it to terminal 100. Terminal 100 can extract voice guidance information from the putting strategy information or generate voice guidance information based on the putting strategy information. In one embodiment, the putting strategy information may include information on putting strength and putting direction. Putting strength may reflect the distance from the ball's position to the hole cup and the slope of the green. For example, if the hole cup is 10 meters away, a strength greater than 10 meters may be indicated if it is uphill. Putting direction may be directional information that indicates the point the player should aim for, relative to the hole cup, taking into account the effect of the left and right slopes of the hole cup on the ball's trajectory. Voice guidance information may be information for providing the player with information on putting strength and putting direction by voice. Terminal 100 can provide voice guidance information to the putting assist device 400.

[0061] The output unit 430 can output voice guidance information received via the communication unit 420 to the player. Therefore, the output unit 430 can include a speaker as described with reference to Figures 2 and 3.

[0062] Figure 5 is a diagram illustrating the operation of the terminal.

[0063] Referring to Figure 5, the terminal 100 may include an input unit 110, a sensor unit 120, an output unit 130, and a communication unit 140. The communication unit 140 may further include an RTK module 141, a wireless communication module 142, and a short-range communication module 143.

[0064] The input unit 110 can receive input from the player. The input unit 110 may include input interfaces such as a touch panel, touch screen, touch pad, touch ball, camera, microphone, gyroscope sensor, vibration sensor, and piezoelectric element.

[0065] The input unit 110 can receive player information from the player. The player information may be information such as an ID and password to identify the player.

[0066] The sensor unit 120 may include a temperature sensor or a humidity sensor for detecting environmental information of the golf course (wind, temperature, humidity, etc.).

[0067] The output unit 130 may include output interfaces such as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode) display device, an AMOLED (Active Matrix OLED) display device, an LED display device, a speaker, or a monitor.

[0068] The communication unit 140 may include an RTK module 141, a wireless communication module 142, and a short-range communication module 143.

[0069] The RTK (Real Time Kinematic) module 141 is a GPS module that incorporates the concept of real-time mobile positioning. It may be a module that uses a correction value for the carrier phase of a base station (GPS Base) with precise position information to obtain accurate positioning results in real time at a mobile station (Rover). Existing GPS modules can suffer from various errors due to the ionosphere, atmosphere, satellite errors, etc., but the RTK module 141 has the advantage of compensating for the decrease in position accuracy caused by signal distortion and delay that occurs when GPS satellite signals pass through the ionosphere, thereby reducing the error to 1-2 cm. In one embodiment, the RTK module 141 can receive RTK correction signals from surrounding base stations using the VRS (Virtual Reference System), FKP (Flachen Korrektur Parameter), MAC (Master Auxiliary Concept), or SSR (State Space Representation) method.

[0070] Since the putting assist device 400 in Figure 4 includes an RTK module, the putting assist device 400 can provide the terminal 100 with position information corrected by the RTK module. Alternatively, in various embodiments, the putting assist device 400 may include only a GPS module, and when the position information acquired by the GPS module is provided to the terminal 100, the RTK module 141 of the terminal 100 can correct the precise position of the putting assist device 400 based on the distance between the terminal 100 and the putting assist device 400.

[0071] In various embodiments, at least two RTK modules can be positioned around the green of each hole on a golf course. In this case, the terminal 100 does not acquire the position of the ball (= position of the putting assist device 400), and the putting assist device 400 can acquire the ball's position information by utilizing at least two RTK modules around the green. For example, the putting assist device 400, as described with reference to Figure 4, can receive a GPS signal and correct the GPS signal by utilizing at least two RTK modules located around the green. In this case, the putting assist device 400 can receive RTK correction signals from at least two RTK modules located around the green using the VRS (Virtual Reference System), FKP (Flachen Korrektur Parameter), MAC (Master Auxiliary Concept), or SSR (State Space Representation) method. In one embodiment, the putting assist device 400 can also acquire the ball's position information using a triangulation method by utilizing the position information of at least two RTK modules located around the green.

[0072] The wireless communication module 142 is for the terminal 100 to connect to the wireless communication network and communicate with the server 200, and may be implemented using various methods such as LTE or 5G depending on the protocol.

[0073] The short-range communication module 143 is a module for communicating with the putting assist device 400 and can provide various short-range wireless communication interfaces such as Bluetooth, Wi-Fi, ZigBee, and ultra-wideband (UWB) communication methods. The short-range communication module 143 can provide the putting assist device 400 with voice guidance information based on putting strategy information received from the server 200.

[0074] The control unit 150 may be a processor that controls the overall operation of the terminal 100. The control unit 150 can control the input unit 110, the sensor unit 120, the output unit 130, and the communication unit 140. In one embodiment, the control unit 150 can provide the server 200 via the wireless communication module 142 of the communication unit 140 with player information received via the input unit 110, environmental information (wind, temperature, humidity, etc.) acquired via the sensor unit 120, and ball position information acquired via the short-range communication module 143. In one embodiment, the control unit 150 can provide the player with putting strategy information by receiving putting strategy information from the server 200 via the wireless communication module 142 and outputting it via the output unit 130.

[0075] Figure 6 is a diagram illustrating the operation of the server.

[0076] Referring to Figure 6, the AI ​​calculation module 210 of the server 200 can receive player information, ball position information, and environmental information from the terminal 100. The AI ​​calculation module 210 can retrieve player record information already stored from the database 300. The player record information may include the average number of putts, putting distance information, putting ball trajectory information, etc., learned from the player's past playing results. The AI ​​calculation module 210 can retrieve golf course information from the database 300. The golf course information may include the terrain information of the golf course, the standard number of strokes for each hole, the slope of the green, the green speed information, the pin position for each hole, and the turf information of the golf course.

[0077] Green speed information can be provided by the golf course. Server 200 can receive green speed information from the golf course using a remote network. Green speed information can be a numerical representation of the speed of the green. Green speed can be obtained by measuring the green speed 3 to 5 times on a flat green surface and dividing the average value by feet. For example, green speed can be calculated by placing a ball on a Stimpmeter on the green, raising the Stimpmeter's incline to 20 degrees, and converting the average distance the ball travels into a numerical value. A higher green speed value indicates a faster green.

[0078] The AI ​​calculation module 210 can generate putting strategy information based on golf course information (particularly using the slope of the green and the green speed) and ball position information. The putting strategy information may include information on putting strength and putting direction. Putting strength can be a strength that reflects the distance from the ball's position to the hole cup and the slope of the green. Putting direction can be directional information that indicates the point the player should aim for, relative to the hole cup, taking into account the effect of the slopes on the left and right of the hole cup on the ball's trajectory.

[0079] In one embodiment, the AI ​​calculation module 210 can generate putting strategy information optimized for the player based on the player's recorded information. For example, the AI ​​calculation module 210 can generate putting strategy information that reflects the average number of putts, putting distance information, and putting trajectory information included in the player's past records.

[0080] Figure 7 is a diagram illustrating the operation method of a putting assistance system according to one embodiment.

[0081] Referring to Figure 7, in step S701, the putting assist device 400 can recognize the player's address posture via a pressure sensor.

[0082] In step S702, the putting assist device 400 provides the terminal 100 with ball position information acquired using a GPS module or RTK module, and in step S703, the terminal 100 can provide the ball position information to the server 200.

[0083] In stage S704, the server 200 generates putting strategy information based on golf course information and ball position information, and in stage S705, the server 200 can provide the generated putting strategy information to the terminal 100.

[0084] In stage S706, terminal 100 can display the received putting strategy information.

[0085] In step S707, terminal 100 can provide voice guidance information to putting assist device 400.

[0086] In step S708, the putting assist device 400 can output voice guidance information to the player via a speaker.

[0087] Figure 8 is an illustrative diagram of putting strategies provided to the player from the terminal and putting assistance device.

[0088] Referring to Figure 8, the output unit 130 of terminal 100 can provide information on the ball's position, the hole cup's position, the green's slope, the ball's predicted direction of travel, and putting strategy information.

[0089] Specifically, the AI ​​caddie's putting strategy advice suggests that, looking at the direction of the hole cup from the current ball position, there is a slope that slopes sharply to the right before becoming gentler. Therefore, aim two cups to the left of the predicted direction of play, and since it is a downhill putt, putt with 60% of your strength.

[0090] On the other hand, the speaker of the putting assist device 400 can output voice guidance information such as "Aim two cups to the left and adjust the putting strength to 60%."

[0091] According to the putting assistance system of one embodiment described above, by using a putting assistance device attached to the grip of the putter to detect when the player takes their address position and to obtain the most accurate ball position in real time, accurate putting strategy information can be provided to the player.

[0092] The present invention is a system that provides a golf player with real-time putting guidance via a putting assistance device 400 attached to a putter, the putting assistance device 400 may include a GPS antenna, an RTK module, a pressure sensor, and a speaker. In particular, the MCU of the putting assistance device 400 may be implemented using a dedicated SoC (System on Chip), or an LTE / WiFi module may be added to overcome the distance limitations of the low-power Bluetooth method, further reducing the weight by reducing battery capacity through low power consumption and miniaturization.

[0093] Although the present invention has been described above with reference to a limited embodiment and drawings, the present invention is not limited to the above-described embodiment, and various modifications and variations can be made from this description by those with ordinary skill in the art to which the present invention belongs.

[0094] Therefore, the scope of the present invention should not be limited to the embodiment described, but should be defined not only by the appended claims, but also by claims equivalent thereto.

[0095] All steps in the embodiment described above may be selectively performed or omitted. Furthermore, the steps in each embodiment do not necessarily have to be performed in order, and the order may be changed.
