Currently, the number of people who enjoy golf has reached approximately several million, and golf-related businesses have also become very active, so the number of golf courses and driving ranges continues to increase. The golf course consists of 18 holes equipped with tee grounds, fairware, rough, greens, holes, hazards, bunkers, etc. The 18 holes include 4 par 5 holes and 4 par 4 holes. It can consist of 10 holes and 4 par 3 holes. The shortest par 3 hole has a course length (length from the tee shot point to the hole cup) of approximately 230 meters or less, and the longest par 5 hole has a course length of approximately 430 meters or more. Since golf has a considerable course length, in order to effectively attack the course, it is very important to determine the current position of the golf ball and based on this, obtain play information such as the distance between the golf ball and the hole cup. In order to determine the distance between the golf ball and the hole cup, golfers purchase a separate measuring device and use it on the golf course.

Figure 1 is a flowchart showing the operation process of a method for determining the position of a golf ball according to an embodiment of the present invention, and Figure 2 is a diagram showing the schematic structure of a system for determining the position of a golf ball according to an embodiment of the present invention. 3 is a diagram to explain the operating principle when applying the golf ball positioning method of FIG. 1 to the golf ball positioning system of FIG. 2.

Referring to Figure 1, the operation process of the method for determining the position of a golf ball according to this embodiment includes first to fourth steps (S1-S4). In the first step (S1), the golf course is divided into a plurality of areas, and a camera covering the corresponding area is placed in each of the divided areas. In the second step (S2), each of the plurality of cameras captures the area it covers to create a captured image. In the third step (S3), a captured image containing a golf ball is extracted from a plurality of captured images captured by a plurality of cameras. In the fourth step (S4), the location of the golf ball is determined by applying the extracted captured image to golf course data for the area covered by the camera that captured the extracted captured image. This method of determining the position of a golf ball can be used in a system for determining the position of a golf ball as shown in FIG. 2.

Referring to FIG. 2, the golf ball location determination system includes a plurality of cameras (C1, C2,..., Cn) and a service device 100. Multiple cameras (C1, C2,..., Cn) are placed throughout the golf course and each covers the area assigned to it. For example, if the golf course is divided into N zones and each divided zone is called the first zone (A1), the second zone (A2),..., the Nth zone (An) (here, the division zone may be divided into overlapping or not overlapping with each other), N plural cameras (C1, C2,..., Cn) are arranged. If the N cameras (C1, C2,..., Cn) are respectively called the first camera (C1), the second camera (C2),..., the N-th camera (Cn), the first camera (C1) is The first area A1 is covered, the second camera C2 covers the second area A2, and the Nth camera Cn covers the Nth area An. Here, the fact that the Kth camera (K is a natural number between 1 and N) covers the Kth area means that the area captured by the Kth camera can cover the entire Kth area. The service device 100 determines the position of the golf ball and delivers it to the golfer, and includes a positioning unit 110 that determines the position of the golf ball and golf course data necessary to determine the position of the golf ball. It includes a storage unit 120 for storing. Although not shown in the drawing, the plurality of cameras C and the service device 100 are all equipped with wireless communication means and can communicate with each other using this.

If the golf ball positioning method of FIG. 1 is applied to the golf ball positioning system of FIG. 2, the first step (S1) in the golf ball positioning method is N golf courses in the golf ball positioning system. It is divided into areas and cameras (C1, C2,..., Cn) are placed in each area, so it is executed through these. In the second step (S2), a captured image is obtained by the cameras (C1, C2,..., Cn) photographing the area they cover. A captured image (first captured image) is obtained for the first area A1 by the first camera C1, and a captured image (second captured image) is obtained for the second area A2 by the second camera C2. image) is obtained,..., a captured image (N-th captured image) for the N-th area (An) is obtained by the N-th camera (Cn). In the third step (S3), the obtained first to Nth captured images are transmitted to the service device 100, and the positioning unit 110 of the service device 100 analyzes the first to Nth captured images to obtain the first The captured image containing the golf ball is extracted from the through Nth captured images. Referring to FIG. 3, assuming that the golf ball is confirmed in the fourth captured image (the image captured by the fourth camera C4 in the fourth area A4), the positioning unit 110 in the fourth step S4 uses the golf course data stored in the storage unit 120 and applies the fourth captured image to it. Golf course data may include first area data, second area data,..., Nth area data corresponding to the first to Nth areas A1,...,An. Additionally, a plurality of horizontal/vertical lines can be applied to the Kth area data (K is a natural number between 1 and N) to the Kth captured image so that the coordinates at a specific location of the Kth captured image can be specified. Therefore, if the fourth captured image is applied to the fourth area data, the coordinates at the position of the golf ball in the fourth captured image can be known. As a result, as shown in FIG. 3, the coordinates (X, Y) at the current position (P) of the golf ball on the golf course can be known.

The location information (P(X, Y)) of the identified golf ball can be used in various ways. First, the distance (D) between the golf ball and the hole cup can be determined using the position information of the golf ball (P(X, Y)) and the position information of the hole cup on the golf course (P0(X0, Y0)). It can be provided to golfers as golf play information. Although not shown in the drawing, the golfer may possess a mobile device such as a smartphone, and the mobile device communicates with the service device 100 to provide information such as the distance D between the golf ball and the hole cup from the service device 100. Golf play information can be received and displayed on the smartphone screen to provide it to the user. Second, the location information of the golf ball (P( You can find out whether you have conquered the golf course and also know your score on the golf course.

Figure 4 is a flowchart showing the operation process of a method for determining the position of a golf ball according to another embodiment of the present invention, and Figure 5 is a diagram showing the schematic structure of a system for determining the position of a golf ball according to another embodiment of the present invention. , Figure 6 is a diagram showing an example of a mobile device that can be used in the golf ball positioning system of Figure 5, and Figures 7 and 8 are diagrams showing the positioning of the golf ball of Figure 4 in the golf ball positioning system of Figure 5. This is a drawing to explain the operating principle when applying the method.

Referring to FIG. 4, the operation process of the method for determining the position of a golf ball according to this embodiment includes first to third steps (S10-S30). In the first step (S10), it is checked whether the golfer is making a swing motion on the golf course. In the second step (S20), the operating position where the swing motion was performed is identified. In the third step (S30), the position of the golf ball on the golf course is determined by applying the motion position identified to the golf course data for the golf course. This method of determining the position of a golf ball can be used in a system for determining the position of a golf ball as shown in FIG. 5.

Referring to FIG. 5, the golf ball location determination system includes a wearable device 1, which can be called a portable device, and a mobile device 10. The wearable device 1 is worn on the golfer's body, and may be, for example, a wrist band type device that can be worn on the golfer's wrist. The wrist band type wearable device 1 may be equipped with a sensor capable of detecting the golfer's swing motion. For example, the wristband-type wearable device 1 may be equipped with a gyro sensor, an acceleration sensor, an impact sensor, etc., and when a golfer makes a swing motion while wearing the wearable device 1, the above The sensor can detect whether the golfer is swinging. A golfer's swing motion can be performed not only when hitting a golf ball, but also when making a practice swing without hitting a golf ball. If an impact detection sensor is present, the impact that occurs when the golfer hits the golf ball can be detected. Therefore, it is possible to distinguish between a simple practice swing and a swing in which a golfer hits a golf ball. By detecting the swing hitting the golf ball, you can determine where the golf ball is placed when the swing hitting the golf ball is made. Practice swings are usually made near the position where the golf ball is placed before hitting the golf ball. Therefore, there is often no significant difference between the location where the practice swing is made and the location where the actual swing that hits the golf ball is made, and taking this into account, an impact detection sensor is not essential.

If the location of the golf ball is identified based on the location where the practice swing was made, play information according to the identified information can be provided to the golfer before actually hitting the golf ball. When the location of the golf ball is determined based on the location of the swing that actually hits the golf ball, the identified information is recorded in the golfer's play record (for example, what path the golf ball took from the tee box to enter the hole). It can be used to create play records regarding the hitting path indicated, etc.).

The wearable device 1 may be equipped with a separate input means such as a button, and a golfer wearing the wearable device 1 may swing at the location where the touch was made by touching the button, etc. before hitting the golf ball. A manual method that considers the position where the motion was performed can also be applied, and in this case, the wrist band may not be equipped with a sensor that can detect the swing motion.

The mobile device 10 may be the golfer's own smartphone. Alternatively, a separate mobile device provided at the golf course that the golfer is using may be used as the mobile device 10, which may be used when the golfer does not possess a smartphone. Referring to FIG. 6, the mobile device 10 is equipped with a position determination unit 11 and a storage unit 12. The positioning unit 11 determines the position of the golf ball and provides golf play information such as the distance between the golf ball and the hole cup, and the storage unit 12 stores data necessary to provide golf play information. The position determination unit 11 and the storage unit 12 can be implemented by installing an app containing a program that determines the location of the golf ball and provides information and related data on the mobile device 10.

When a smartphone is used as the mobile device 10, the location of the mobile device 10 can be determined by receiving a signal from the GPS satellite 101. Here, the case of receiving signals from the GPS satellite 101 to obtain location information of the mobile device 10 has been described, but satellite signals do not necessarily have to be used when acquiring location information, and other methods of obtaining location information are available. It may also apply.

When applying the golf ball positioning method of FIG. 4 to the golf ball positioning system of FIG. 5, in the first step (S10) of the golf ball positioning method, as shown in FIG. 7, a wearable device ( 1) A golfer hits a golf ball while wearing a golf ball. The wearable device 1 is equipped with a sensor that can detect the user's practice swing motion or the swing motion of the user hitting a golf ball, and when the swing motion is detected, a communication means separately provided in the wearable device 1 A signal is transmitted to this mobile device 10. If the wearable device 1 is not equipped with a sensor that detects swing motion, the golfer can directly input that the swing is made at the current position by touching a separately provided input means before swinging, and in this case as well, The communication means can transmit a signal to the mobile device 10. In the second step (S20), when the mobile device 10 receives the signal, the mobile device 100 determines the location of the golf ball using the GPS satellite 101 (see FIG. 5). Here, the position where the golf ball is placed before hitting is called the golf ball position (P), the position of the wearable device 1 is called the first position (P1), and the position of the mobile device 10 is called the second position (P2). ), in this embodiment, it is assumed that the first position (P1) or the second position (P2) is the position (P) of the golf ball.

The first position P1 is the position of the wearable device 1, and can actually be viewed as the position of the golfer wearing it. Since the golfer hits the golf ball while being close to the golf ball, it can be said that there is no problem even if the golfer's position (the first position (P1)) is assumed to be the position (P) of the golf ball. If the mobile device 10 is a golfer's smartphone and the golfer is carrying his/her smartphone while playing golf, the second position (P2) becomes the golfer's position, and the golfer hits the golf ball while being close to the golf ball. Therefore, it can be said that there is no problem even if the second position (P2) is assumed to be the position (P) of the golf ball. If the mobile device 10 is separated from the wearable device 1 to some extent (e.g., when a golfer places his smartphone, which is the mobile device 10, on a cart on a golf course and plays), the mobile device 10 can be connected to the wearable device 1 through a GPS satellite signal. First, the second location (P2) of the mobile device 10 is determined, and the location of the wearable device 1 is tracked in the mobile device 10 through communication between the mobile device 10 and the wearable device 1. The first position (P1) can be determined from the position (P2), and the identified first position (P1) can be regarded as the position (P) of the golf ball.

Referring to FIG. 8, golf course data for the golf course currently being played is stored in the storage unit 12, and in the third step (S30), the location detection unit 11 of the mobile device 10 detects the storage unit 12. ) and apply the motion position (first position (P1) or second position (P2)) where the golfer's swing was made to it. Here, the golf course data includes map data of the golf course that the golfer is currently playing, and coordinates may be set for each location on the map. When the operation position (first position (P1) or second position (P2)) is combined with the golf course map whose coordinates are set in this way, the coordinates (X, Y) representing the position (P) of the golf ball can be identified. You can.

If the user determines the position information (P(X, Y)) of the golf ball through a practice swing before hitting the golf ball, the position information (P0(X0, Y0)) of the hole cup on the golf course is used to The distance (D) between the golf ball and the hole cup can be determined, and this can be displayed on the screen of the mobile device 10 and provided to the golfer. Alternatively, as shown in FIG. 7, if the golf ball's location information (P( You can find out what kind of hitting path the user used to attack the golf course and the user's score on the golf course.

According to this embodiment, when a golfer makes a specific motion, in determining the position of the golf ball by tracking the position of the motion, the motion is referred to as a 'swing motion' and a 'wrist band' is used as a device that detects this swing motion. This type of wearable device is used, which can have significant effects. If you select 'swing motion' as the motion to start tracking the position of the golf ball, the 'swing motion' is performed near the point where the golf ball is placed, so there is no problem even if the position of the swing motion is regarded as the position of the golf ball. There is an advantage. In addition, when selecting a different action as an action to start tracking the position of the golf ball, there is an inconvenience in that the golfer has to take that action separately during golf play. As in the present invention, the action to start tracking the position of the golf ball is inconvenient. In the case of selecting the swing motion, there is an advantage that the golfer does not need to take any other separate motion to start tracking the position of the golf ball because the swing motion is an unconditionally necessary motion in playing golf. In addition, when a 'wrist band' is used as a sensor to detect 'swing motion', the arm moves every time the golfer makes a swing motion, and the arm movement can be naturally transmitted to the wrist band worn on the wrist. It has the advantage of accurately capturing the golfer's swing motion. Additionally, since it is worn on the wrist, it has the advantage of hardly interfering with the golfer's golf play. In this way, when 'swing motion' is selected as the motion to start tracking the position of the golf ball and the 'wrist band' type is used as a device that detects the 'swing motion' at the same time, there are two configurations: swing motion and wrist band. Combined, this produces a remarkable effect. Here, instead of using a separate wrist band, the golfer's smartphone can be used as both a wearable device (1) and a mobile device (10). In other words, if a golfer wears an arm band on his arm and attaches a smartphone to the arm band, most smartphones have a vibration detection function, so the smartphone can detect when a swing occurs. By using the smartphone's location tracking function, you can determine the location where the swing action was made, and by applying the location where the swing action was made to the golf course data, you can obtain the location of the golf ball and various play information (distance between the golf ball and the hole cup, etc.) ) can be identified and provided to golfers.

Figure 9 is a diagram showing the schematic structure of a golf ball positioning system according to another embodiment of the present invention, and Figure 10 shows the operating principle of determining the position of the golf ball in the golf ball positioning system of Figure 9. This is a drawing for explanation.

Referring to FIG. 9, the golf ball location determination system includes mobile devices 10, 20, and 30 and a service device 100. The golfer's own smartphone, etc. may be used as the mobile device 10, 20, or 30. Here, it is assumed that there are multiple golfers, and each of the multiple golfers possesses their own mobile device (10, 20, and 30). For example, if there are three golfers and they are referred to as the first golfer, the second golfer, and the third golfer for convenience, the mobile devices 10, 20, and 30 are the first mobile device 10 and the third golfer owned by the first golfer. 2. Includes a second mobile device (20) possessed by a golfer and a third mobile device (30) possessed by a third golfer. The service device 100 determines the position of the golf ball and delivers it to the golfer, and includes a positioning unit 110 that determines the position of the golf ball and golf course data necessary to determine the position of the golf ball. It includes a storage unit 120 for storing. The mobile devices 10, 20, and 30 and the service device 100 are connected through a network. The mobile devices 10, 20, and 30 have a location tracking function. For example, the mobile devices 10, 20, and 30 may be located using a GPS satellite 101. Since the positions of the mobile devices 10, 20, and 30 indicate the positions of the golfer carrying them, the location of the first golfer can be determined through the first mobile device 10, and the location of the first golfer can be determined through the second mobile device 20. The location of the second golfer can be determined, and the location of the third golfer can be determined through the third mobile device 30.

In the golf ball positioning system according to this embodiment, the operation process of determining the position of the golf ball includes the steps of the positioning unit 110 identifying the motion position where the golfer's swing motion has been made (or will be made), and position determination. It includes a step where the unit 110 determines the position of the golf ball on the golf course by applying the motion position identified to the golf course data for the golf course in the storage unit 120. As for the operating position, when one golfer among a plurality of golfers is positioned away from the remaining golfers, the current position of the golfer who is spaced apart is regarded as the operating position. For example, as shown in Figure 10, the positions (P2, P3) of the second and third golfers are adjacent to each other and the position (P1) of the first golfer is adjacent to the positions (P2) of the second and third golfers. , P3), this can be seen as the first golfer being separated from the second and third golfers in order to hit his golf ball. Therefore, if the first golfer is positioned alone away from other golfers for a certain amount of time (the time required for the movement of the practice swing), assuming that the swing movement was made by the first golfer at that location, the position of the first golfer Information (P1(X1, Y1)/position information of the second golfer (P2(X2, Y2)/position information of the third golfer (P3(X3, Y3)) is regarded as the positional information (P( In addition, each time a golf ball is hit, the location information of the golf ball can be obtained to determine the hitting path and score played by the golfer on the golf course. Here, one golfer among a plurality of golfers is adjacent to each other. It is said that when a golfer is positioned at a certain distance from the rest of the golfers for a certain period of time, the swing motion can be considered to have occurred at the position of the lone golfer. In addition to this, a swing motion can be considered to have occurred when multiple golfers are in a specific positional relationship with each other. There may be various situations. AI technology may be applied to determine various situations in which the swing motion occurs. For example, AI technology such as machine learning is applied to the positioning unit 110 of the service device 100. If introduced and the AI is taught various data ((positional relationship between golfers), (whether the golfer swings)), the swing movement is performed while the AI checks the positional relationship between a plurality of golfers. You can determine whether it can be considered a location.

Figure 11 is a diagram showing the schematic structure of a golf ball location detection system according to another embodiment of the present invention.

Referring to FIG. 11, the golf ball location determination system includes a plurality of cameras (C1, C2,..., Cn), a wearable device (1), a mobile device (10), and a service device (100). Multiple cameras (C1, C2,..., Cn) are placed throughout the golf course and each covers the area assigned to it. For example, if the golf course is divided into N zones and each divided zone is called the first zone (A1), the second zone (A2),..., the Nth zone (An) (here, the division zone may overlap each other or be distinguished from each other), the first camera C1 covers the first area A1, and the second camera C2 covers the second area A2. .., the Nth camera (Cn) covers the Nth area (An). The wearable device 1 is worn on the golfer's body, and may be, for example, a wrist band type device that can be worn on the golfer's wrist. The wrist band type wearable device 1 is equipped with a sensor that can detect the golfer's swing motion. The mobile device 10 may be the golfer's own smartphone. Smartphones have a location tracking function, and for example, the location of the mobile device 10, which is a smartphone, can be determined using the GPS satellite 101. The service device 100 determines the position of the golf ball and delivers it to the golfer, and includes a positioning unit 110 that determines the position of the golf ball and golf course data necessary to determine the position of the golf ball. It includes a storage unit 120 for storing. Although not shown in the drawing, the plurality of cameras (C) and the service device 100 are all equipped with a wireless communication means and can communicate with each other using this, and when a smartphone is used, the mobile device 10 is also provided with the service. It is possible to communicate with the device.

The golf ball location detection system according to this embodiment has both the configuration of the system shown in FIG. 2 and the configuration of the system shown in FIG. 5. Therefore, the golf ball positioning process in the above-described systems can be applied in combination to the golf ball positioning system according to this embodiment. That is, a plurality of cameras (C1, C2,..., Cn) extract a captured image containing a golf ball from captured images of the area they cover, and then apply the extracted captured image to the golf course data to create a golf ball. The position of the golfer can be determined (named 'first process' for convenience), and whether the golfer is making a swing motion is detected by the wearable device (1) worn by the golfer, and the location where the swing motion was made is applied to the golf course data. Thus, the position of the golf ball can be determined (for convenience, it is called the 'second process'). The first and second processes can be carried out separately from each other, or if a problem arises while proceeding with only one of the two, the other process can be carried out additionally, or the first and second processes can be carried out together to complement each other, etc. can be used For example, when the first and second processes are carried out together, the position of the golf ball is determined through the second process, a captured image is generated from a camera covering the identified position, and the generated captured image is used to We can think of a way to finally determine the location of the golf ball. This method takes into account the fact that the position of the golf ball determined in the second process represents the position of the golfer and may be different from the exact position of the golf ball. The position of the golfer is first identified through the second process, and then again in the first process. By proceeding with the process, the exact location of the golf ball can be identified and some of the processes during the first process are omitted (not targeting the entire golf course, but the location to which the golfer is identified in the first process belongs. There is an advantage in that the first process can be conducted targeting only the area.
