[0003] FIG. 3 is a diagram illustrating a method of analyzing a golf shot using a device according to a prior art.

[0004] Referring to FIG. 3, a prior art technique for analyzing a golf shot using a device (e.g., a golf launch monitor) has been proposed, wherein a user places the device on the ground, places a separate adjustment stick (e.g., an alignment stick) in the direction of a target, and corrects golf shot data using the adjustment stick.

[0005] However, according to these conventional technologies, the user directly places the adjustment stick on the ground, and the device detects the direction of placement of the adjustment stick to correct the golf shot data. Therefore, there was a problem in that it was difficult to accurately analyze the golf shot due to errors that occurred when the user did not place the adjustment stick in the correct direction.

[0006] Accordingly, the inventor(s) of the present invention propose a technology that enables a golf shot to be precisely analyzed by obtaining at least one of first information regarding a reference position and second information regarding a target position, and determining adjustment information of a device for analyzing a golf shot by referring to at least one of the first information and the second information.

[0007] The purpose of the present invention is to solve all of the problems of the above-mentioned prior art.

[0030] Next, a golf shot analysis system (200) according to one embodiment of the present invention may perform a function of obtaining at least one of first information regarding a reference position and second information regarding a target position, and determining adjustment information of a device for golf shot analysis by referring to at least one of the first information and the second information.

[0031] The configuration and function of the golf shot analysis system (200) according to the present invention will be described in detail below.

[0032] Next, a device (300) according to one embodiment of the present invention is a digital device that includes a function for communicating after being connected to a golf shot analysis system (200), and any digital device that has a memory means, a microprocessor, and a computing capability, such as a smart phone, a tablet, a smart watch, a smart band, smart glasses, a desktop computer, a notebook computer, a workstation, a PDA, a web pad, a mobile phone, etc., can be adopted as the device (300) according to the present invention.

[0033] In particular, the device (300) may include an application (not shown) that supports a user to receive functions according to the present invention from the golf shot analysis system (200). Such an application may be downloaded from the golf shot analysis system (200) or an external application distribution server (not shown). Meanwhile, the nature of such an application may be generally similar to the information acquisition unit (210), the adjustment information determination unit (220), the communication unit (230), and the control unit (240) of the golf shot analysis system (200), which will be described later. Here, at least a part of the application may be replaced with a hardware device or firmware device that can perform functions substantially identical to or equivalent thereto, as necessary.

[0034] Composition of a golf shot analysis system

[0035] Below, the internal configuration and functions of each component of the golf shot analysis system (200) that performs important functions for implementing the present invention will be examined.

[0036] FIG. 2 is a drawing showing in detail the internal configuration of a golf shot analysis system (200) according to one embodiment of the present invention.

[0037] As illustrated in FIG. 2, a golf shot analysis system (200) according to one embodiment of the present invention may be configured to include an information acquisition unit (210), an adjustment information determination unit (220), a communication unit (230), and a control unit (240). According to one embodiment of the present invention, at least some of the information acquisition unit (210), the adjustment information determination unit (220), the communication unit (230), and the control unit (240) may be program modules that communicate with an external system (not shown). These program modules may be included in the golf shot analysis system (200) in the form of an operating system, an application program module, or other program modules, and may be physically stored in various known memory devices. In addition, these program modules may be stored in a remote memory device that can communicate with the golf shot analysis system (200). Meanwhile, these program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks or execute specific abstract data types, which will be described later, according to the present invention.

[0038] Meanwhile, although the golf shot analysis system (200) has been described as above, this description is exemplary, and it is obvious to those skilled in the art that at least some of the components or functions of the golf shot analysis system (200) may be realized within a device (300) or a server (not shown) or included within an external system (not shown) as needed.

[0039] First, the information acquisition unit (210) according to one embodiment of the present invention can perform a function of acquiring at least one of first information regarding a reference position and second information regarding a target position.

[0040] Specifically, the first information according to one embodiment of the present invention may include at least one of location information of a user (e.g., a golfer) and location information of a golf ball. Here, the location information of the user according to one embodiment of the present invention may include at least one of information regarding the location of the batting box where the user is located and information regarding the locations of the user's two feet (e.g., information regarding the center locations of the user's two feet), but is not limited thereto. In addition, the location information of the golf ball according to one embodiment of the present invention may include location information of a golf ball that the user places on the ground for a golf swing. In addition, according to one embodiment of the present invention, the reference location may be determined as the location of the user or the location of the golf ball based on a user input or a preset condition.

[0041] Additionally, the first information according to one embodiment of the present invention may include information regarding the distance between the reference location and the device. Specifically, according to one embodiment of the present invention, the user's location information may include information regarding the distance between the user's location and the device. Furthermore, according to one embodiment of the present invention, the golf ball's location information may include information regarding the distance between the golf ball's location and the device.

[0042] Additionally, the second information according to one embodiment of the present invention may include information regarding a target location (e.g., the location of the hole cup). Specifically, the target location according to one embodiment of the present invention may refer to a virtual target location (e.g., the location of the hole cup on a screen golf system) on a virtual golf simulator system (not shown) or the location of the hole cup on an actual golf course, but is not limited thereto. For example, the target location according to one embodiment of the present invention may refer to a specific location input (or selected) by a user on a virtual golf simulator system or an actual golf course, rather than the location of the hole cup.

[0043] For example, the information acquisition unit (210) according to one embodiment of the present invention may acquire at least one of the first information and the second information from at least one image sensor included in the device. Specifically, at least one of the first information and the second information according to one embodiment of the present invention may be acquired by capturing an image at a time point after the user stands at the batting cage to prepare for a golf shot or after the user places a golf ball on the ground for a golf shot. In addition, the image sensor according to one embodiment of the present invention may include a video sensor that captures a plurality of consecutive images.

[0044] For example, according to one embodiment of the present invention, the information acquisition unit (210) may acquire at least one of the first information and the second information in response to the user's position at the tee or the golf ball being placed on the ground (e.g., placed for a golf shot). Accordingly, according to the present invention, at least one of the first information and the second information may be acquired before the user's golf shot is made, and precise adjustment information may be determined.

[0045] For another example, a device according to an embodiment of the present invention may refer to a Golf Launch Monitor as a device for analyzing a golf shot, but is not limited thereto. Any device capable of obtaining at least one of the first information and the second information may be included in the device according to the present invention. In addition, the device according to an embodiment of the present invention may include at least one sensor (e.g., an image sensor or a radar sensor, etc.).

[0046] For another example, a device according to an embodiment of the present invention may include at least one radar sensor. Specifically, a radar sensor according to an embodiment of the present invention may refer to a sensor for obtaining information on at least one of a position, a speed, and a direction of an object using electromagnetic waves. For a specific example, an information obtaining unit (210) according to an embodiment of the present invention may obtain at least one of first information (e.g., a distance between a reference position and the device) and second information (e.g., a distance between a position of a golf ball and the device) from a radar sensor included in the device.

[0047] For another example, the information acquisition unit (210) according to one embodiment of the present invention may estimate at least one of a reference position and a target position based on two or more images acquired from each of two or more image sensors included in the device, and may acquire the estimation result as at least one of the first information and the second information.

[0048] For example, two or more image sensors according to one embodiment of the present invention may be spaced apart from each other and included (or equipped) in a device. Here, the information acquisition unit (210) according to one embodiment of the present invention may estimate at least one of a reference position and a target position based on a phase difference between two or more images acquired from each of the two or more sensors. In addition, the information acquisition unit (210) according to one embodiment of the present invention may acquire the estimation result as at least one of the first information and the second information. In addition, according to one embodiment of the present invention, the process of estimating at least one of the reference position and the target position based on two or more images may be performed by using a stereo vision method. In addition, the stereo vision method according to one embodiment of the present invention may mean a method of estimating distance information (e.g., depth information) to an object by calculating two or more images acquired from two or more sensors placed at different locations.

[0049] Therefore, according to the present invention, at least one of the first information and the second information can be estimated from two or more images rather than from a user's arbitrary input, thereby enabling precise golf shot analysis.

[0050] Meanwhile, the information acquisition unit (210) according to one embodiment of the present invention may acquire at least one of the first information and the second information from at least one sensor not included in the device. That is, at least one sensor (i.e., an image sensor, a radar sensor, etc.) according to one embodiment of the present invention is not necessarily included in the device, and may be included in a system inside or outside the golf shot analysis system (200).

[0051] As another example, the information acquisition unit (210) according to one embodiment of the present invention can acquire at least one of the first information and the second information from the virtual golf simulator system.

[0052] For example, the information acquisition unit (210) according to one embodiment of the present invention may acquire second information (e.g., information on the location of a hole cup in a virtual golf simulator game) from a virtual golf simulator system. In addition, the information acquisition unit (210) according to one embodiment of the present invention may acquire first information (e.g., information on the location of a user in a virtual golf simulator game) from a virtual golf simulator system.

[0053] As another example, the information acquisition unit (210) according to one embodiment of the present invention can acquire at least one of the first information and the second information based on a user's input.

[0054] For example, according to one embodiment of the present invention, a user may input information regarding the distance (e.g., 95 m) between the device and a target location into the device. Here, the information acquisition unit (210) according to one embodiment of the present invention may acquire second information based on the user's input.

[0055] As another specific example, the information acquisition unit (210) according to one embodiment of the present invention can acquire first information from at least one sensor and acquire second information based on a user's input.

[0056] As another specific example, according to one embodiment of the present invention, a user may input specific reference target distance information (e.g., 300 m) from among at least one reference target distance information (e.g., 100 m, 200 m, 300 m, 400 m, and 500 m) onto the device. Here, the information acquisition unit (210) according to one embodiment of the present invention may acquire the specific reference target distance information input as second information. In other words, the information acquisition unit (210) according to one embodiment of the present invention may acquire specific reference target distance information input by the user from among at least one reference target distance as second information.

[0057] Accordingly, according to the present invention, if the user knows in advance information about the distance between the device and the target location, the second information can be obtained based on the user's input, and even if the user does not specifically know information about the distance between the device and the target location, the second information can be obtained by inputting reference target distance information.

[0058] As another example, the information acquisition unit (210) according to one embodiment of the present invention may acquire at least one of information about a golf course and information about a current location of a user on a golf course from a virtual golf simulator system, determine a distance between the user's location and a target location by referring to the golf course and the user's current location on the golf course, and acquire the determined distance between the user's location and the target location as second information.

[0059] For example, according to one embodiment of the present invention, it may be assumed that a user is preparing a tee shot at hole 1 on a specific golf course. Here, the information acquisition unit (210) according to one embodiment of the present invention may acquire information about the golf course and information about the user's current location, and determine the distance between the user's location and the target location by referring to the golf course and the user's current location on the golf course (for example, determining that the distance from the teeing ground of hole 1 to the hole cup is 340 m), and may acquire the determined distance (for example, 340 m) as second information. Here, the information acquisition unit (210) according to one embodiment of the present invention may further acquire the first information from at least one image sensor, but may acquire the first information from a virtual golf simulator system.

[0060] Next, the adjustment information determination unit (220) according to one embodiment of the present invention can perform a function of determining adjustment information of a device for golf shot analysis by referring to at least one of the first information and the second information.

[0061] Specifically, the adjustment information of the device according to one embodiment of the present invention may include information (e.g., calibration information for image transformation) applied to at least one image of a golf shot for analyzing the golf shot. In addition, the adjustment information of the device according to one embodiment of the present invention may include adjustment information for correcting a difference (e.g., an angular difference between the two directions) between the direction from the user's position (or the position of the golf ball) to the target position and the direction from the device to the target position.

[0062] For example, the adjustment information determination unit (220) according to one embodiment of the present invention can determine the adjustment information by calculating the angle between a first direction from a reference position to a target position and a second direction from the device to the target position.

[0063] FIG. 4 is a diagram exemplarily illustrating a situation in which adjustment information of a device is determined according to one embodiment of the present invention, and FIG. 5 is a diagram exemplarily illustrating a situation in which adjustment information of a device is determined according to one embodiment of the present invention.

[0064] For example, referring to FIG. 4, the adjustment information determining unit (220) according to one embodiment of the present invention can determine the adjustment information by calculating the angle between the first direction (510) from the reference position (400) to the target position (500) and the second direction (520) from the device (300) to the target position (500).

[0065] For another example, referring to FIG. 5, the adjustment information determining unit (220) according to one embodiment of the present invention can determine the adjustment information by calculating the angle between the first direction (510) from the user's position to the target position (500) and the second direction (520) from the device (300) to the target position (500), corresponding to the reference position being determined as the user's position. Here, referring to FIG. 5, the adjustment information determining unit (220) according to one embodiment of the present invention can calculate the angle between the first direction (510) and the second direction (520) based on the ratio of the distance (410) between the user's position and the device and the distance (521) between the device and the target position. For example, the adjustment information determination unit (220) according to one embodiment of the present invention can calculate the angle between the first direction (510) and the second direction (520) by applying an arc tangent function to the distance (410) between the user's position and the device and the distance (521) between the device and the target position.

[0066] For another example, referring to FIG. 5, the adjustment information determining unit (220) according to one embodiment of the present invention may determine the adjustment information by calculating an angle between a first direction (510) from the position of the golf ball to the target position (500) and a second direction (520) from the device (300) to the target position (500), corresponding to the reference position being determined as the position of the golf ball. Here, referring to FIG. 5, the adjustment information determining unit (220) according to one embodiment of the present invention may calculate the angle between the first direction (510) and the second direction (520) based on a ratio of a distance (420) between the position of the golf ball and the device and a distance (521) between the device and the target position. In addition, according to one embodiment of the present invention, the calculation of the angle between the first direction (510) and the second direction (520) based on the ratio may be calculated by applying an arc tangent function as described above.

[0067] Meanwhile, the method of determining adjustment information according to the present invention is not limited to the above-described method, and may be changed in various ways within the scope that can achieve the purpose of the present invention.

[0068] Meanwhile, the golf shot analysis system (200) according to one embodiment of the present invention may further include a golf shot analysis unit (not shown).

[0069] A golf shot analysis unit according to one embodiment of the present invention may perform a function of acquiring at least one image related to a golf shot and analyzing the golf shot by applying adjustment information to the at least one image. Here, the analysis of the golf shot according to one embodiment of the present invention may be performed by a component (e.g., a processor, etc.) within the device, but may also be performed by a component included in the golf shot analysis system (200) or an external system. In addition, the at least one image related to the golf shot according to one embodiment of the present invention may be acquired from at least one image sensor that captures the user's golf shot, but is not limited thereto.

[0070] For example, a golf shot analysis unit according to an embodiment of the present invention may generate first analysis information analyzing a golf shot using at least one image related to the golf shot. In addition, a golf shot analysis unit according to an embodiment of the present invention may generate second analysis information analyzing a golf shot by applying adjustment information to at least one image related to the golf shot. In addition, a golf shot analysis unit according to an embodiment of the present invention may provide at least one of the first analysis information and the second analysis information through a display on a device. Here, at least one of the first analysis information and the second analysis information according to an embodiment of the present invention may include, but is not limited to, a speed of a golf ball, a spin of a golf ball, and the like, and any physical quantity associated with a golf ball that can analyze a golf shot may be included therein.

[0071] Therefore, according to the present invention, a user can compare first analysis information to which adjustment information is not applied and second analysis information to which adjustment information is applied, and can specifically analyze a golf shot.

[0072] Next, the communication unit (230) according to one embodiment of the present invention can perform a function that enables data transmission and reception from / to the information acquisition unit (210) and the adjustment information determination unit (220).

[0073] Lastly, the control unit (240) according to one embodiment of the present invention can perform a function of controlling the flow of data between the information acquisition unit (210), the adjustment information determination unit (220), and the communication unit (230). That is, the control unit (240) according to one embodiment of the present invention can control the flow of data from / to the outside of the golf shot analysis system (200) or the flow of data between each component of the golf shot analysis system (200), thereby controlling the information acquisition unit (210), the adjustment information determination unit (220), and the communication unit (230) to perform their own unique functions.
