Description

[Technical field]

[0001] The present invention relates to a motion sensor-based smart golf round information system, and more particularly to a motion sensor-based smart golf round information system capable of transmitting golf round information to a portable device based on motion sensors included in the portable device. [Background technology]

[0002] The contents described in the "Background Art" are intended to deepen understanding of the background of the invention, and may include contents that are not prior art known to those skilled in the art.

[0003] Generally, golf is defined as the sport of hitting a small golf ball accurately, and it is recognized that the most important thing in golf is to teach your body how to swing correctly. Golfers, whether professional or amateur, are known to make great efforts to learn the correct stance and improve their swing.

[0004] Especially when playing a round on the golf course, golfers who achieve good results will want to commemorate their results by recording a video of their swing and stance, while golfers who do not perform so well will also often want to take videos to identify problems with their swing.

[0005] However, conventional golf swing video devices and systems use sound sensors to detect the sound of the impact when the user hits the ball, taking a video of the moment of impact as a reference, and then cutting out and providing the swing video.

[0006] Various prior art documents, including Korean Patent Application No. 2000-0002408, Korean Patent Application No. 1994-7002515, Korean Patent Application No. 2012-0131412, and the like, disclose, as examples, methods for identifying the moment of impact using a sound sensor.

[0007] However, after conducting several experiments, the applicant came to the conclusion that identifying the moment of impact using only a sound sensor and using that as a reference to extract a video of a user's swing from a captured video would produce unreliable results.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The advantages, features, and methods of achieving the present invention will be described below with reference to the accompanying drawings, using the following embodiments of the present invention. However, the embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the following, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims. The embodiments are intended to complete the disclosure of the present invention and to deepen the understanding of those skilled in the art of the gist of the present invention, and the present invention is defined only by the claims.

[0020] Figure 1 is a schematic diagram of a motion sensor-based smart golf round information system according to an embodiment of the present invention. Figure 2 is a schematic diagram of a GPS according to an embodiment of the present invention. Figure 3 is a schematic diagram of a motion sensor according to an embodiment of the present invention.

[0021] 1 and 2, a motion sensor-based smart golf round information system (1000) (hereinafter referred to as the "smart golf round information system") includes a portable device (100), a golf course terrain database (200), and a server (300).

[0022] The portable device (100), the terrain database (200), and the server (300) are interconnected via a communication network.

[0023] Here, the term "communication network" refers to a wired network such as the Internet, a wireless network, or a combination thereof. In one embodiment of the present invention, the type of network is not particularly limited, and may be interpreted as including all conventional Internet and mobile communication networks.

[0024] For example, the portable device (100), the topographical database (200), and the server (300) may be connected by various combinations of conventional networks such as the Internet or a mobile communication network, and there is no particular restriction on the connection method.

[0025] A golfer can use the smart golf round information service by downloading and installing a smart golf round information application on a portable device (100) and running the application to access the smart golf round information system (1000).

[0026] The configuration of the golf round information system (1000) will be described below.

[0027] The portable device (100) is housed in a wearable member attached to a part of the golfer's body, and includes a motion sensor (110) and a GPS (120, Global Positioning System). The portable device (100) may be configured to have a variety of functions in addition to the motion sensor (110) and the GPS (120, Global Positioning System). The motion sensor (110) may be configured to include an acceleration sensor (111) and a gyroscope sensor (112). The wearable member may be a strap, a bag, or the like.

[0028] The golf course terrain database (200) stores the terrain data of the golf course where the golfer is currently standing. The golf course terrain data may display not only the specific terrain of the golf course, but also the position of the hole.

[0029] The server (300) receives motion data of the portable device (100) from the motion sensor (110) in real time to detect the golfer's swing (practice swing, swing), and reads the terrain data of the golf course from the terrain database (200).

[0030] The server (300) further receives GPS position information of the portable device (100) from the GPS (120) and corrects the current position of the portable device (100) by combining the golf course topographical data with the GPS position information.

[0031] After the play of each hole is completed, the score determined based on the number of swings detected by the motion sensor (110) is transmitted to the server (300). The server (300) estimates the position where the penalty stroke occurred from the score and stores it.

[0032] If the server (300) detects two swings from a golfer at the same position within a set time, it considers the swing to be out of bounds (OB) and incurs a penalty stroke.

[0033] The server (300) will add a penalty stroke as a penalty in a hazard when it is detected that the golfer has moved toward the cart to retrieve the ball or has leaned forward to place the ball on the ground.

[0034] Of course, the method of determining the penalty strokes is not limited to the above embodiment, and various methods may be applied to determine the penalty strokes.

[0035] The server (300) transmits round information to the portable device (100) based on the swing information at the location where the golfer is located.

[0036] The round information may be at least one of the following: tee shot distance, OB rate, hazard rate, approach accuracy, and putting accuracy.

[0037] In addition, the server (300) provides strategy information for each hole, including the distance from the current position to the pin and the elevation difference, based on the terrain data and the GPS position information of the golfer received from the GPS. The server (300) also provides strategy information for the green, based on the slope of the green and the position of the hole cup.

[0038] The round information may be statistics on scores on any one of the following: uphill sections of the course, penalty areas, and dog-legs. A dog-leg is a curve in the course or hole that turns to the left or right halfway through the course, like the hind leg of a dog.

[0039] The score may be calculated in combination with the number of swings of the golfer. See FIG. 4 for a method of calculating the score in combination with the number of swings of the golfer.

[0040] FIG. 4 is a topographical map of a golf course for explaining round information according to an embodiment of the present invention.

[0041] In Figure 1 and Figure 4, the point indicated by the black downward arrow is the location of the tee, the dashed line is the golfer's movement line, the green diamond is the location where the swing motion was detected, the orange diamond is the location where the ball placement motion and swing motion were detected, and the black circle is the hole.

[0042] The first hole (h1) is a par 4 hole, but the golfer finished in 5 strokes, so it is a bogey. A bogey is a golfer finishing in one more stroke than the par for that hole.

[0043] On the par 3 second hole (h2), three swings are detected, but it is determined that the golfer leans forward once to place the golf ball, which is deemed a penalty in the hazard and is also ruled a bogey.

[0044] As described above, by transmitting round information from the server (300) to the portable device (100) carried by the golfer, the golfer can accurately and easily grasp his / her score based on the round information, and can improve his / her ability.

[0045] 5 is a flowchart of a motion sensor-based smart golf round information providing method according to an embodiment of the present invention. For a detailed description of S100 to S500, please refer to the description of FIGS. 1 to 3 above.

[0046] First, a golfer starts a round by attaching a portable device (100) to a part of his / her body (S100). The position of the portable device can be anywhere, but it is generally attached to the golfer's waist.

[0047] After S100, the portable device (100) transmits the GPS location information and the operation data to the server (300) (S200). The server (300) may be installed anywhere within the golf course, and is preferably installed in a management office that manages the facilities of the golf course.

[0048] After S200, the swing is detected based on the golfer's motion data (S300). Through S200 to S300, the server (300) recognizes and stores the golfer's movement and swing time over time. The golfer's movement line can be determined from GPS position information, and the golfer's swing time can be determined from the motion data.

[0049] After S300, the server adds penalty strokes as a penalty for OB or hazard (S400). Specifically, when the server (300) detects a golfer's swing twice at the same position within a set time, it considers it to be OB (out of bounds) and adds a penalty stroke. The set time may be 5 seconds or 10 seconds, but is not particularly limited. Furthermore, when the server (300) detects that the golfer has moved toward the cart to retrieve the ball or that the golfer has leaned forward to place the ball on the ground, it adds a penalty stroke as a penalty for hazard.

[0050] OB, or out of bounds, refers to a ball going outside the designated area of ​​each hole (outside the playable area). Hazards are obstacle areas intentionally placed when designing a golf course. They are placed on the golf course to increase the difficulty or to enhance the beauty of the scenery.

[0051] Alternatively, in order to calculate the score accurately, a camera may be provided and the captured image information may be utilized. The camera is to be provided at one or more locations on the golf course, but there is no particular restriction on the location.

[0052] After S400, the server (300) sends round information to the golfer's portable device (100) (S500), where the round information is at least one of the following: tee shot distance, OB ratio, hazard ratio, approach accuracy, and putting accuracy.

[0053] The round information may be a score statistic on any one of the uphill sections of the course, the penalty areas, and the doglegs, and the score may be calculated in combination with the number of swings of the golfer.

[0054] The above-mentioned embodiment of the present invention has been described with reference to the drawings for better understanding, but the present invention is not limited thereto, and the embodiment is merely an example of the present invention. Those skilled in the art should understand that various modifications and variations are possible, and the scope of protection of the present invention is defined only by the appended claims.
