Description

Method and system for displaying information about a golf swing

[0001] The present invention relates to a method and system for displaying information regarding a golf swing.

[0002] With the recent increase in leisure time and the growing number of people enjoying golf, the domestic and international golf industry is steadily growing, and various technologies are being proposed to support the improvement of golf skills.

[0003] Golf is a sport in which a user (e.g., a golfer) swings a golf club to send a golf ball to a target location. Therefore, if an incorrect posture is adopted during a golf swing, it can have a significant impact on the outcome of the golf swing (e.g., loss of distance).

[0004] As a prior art related to a method for correcting posture during a golf swing, a technology has been proposed in which an image of a user's posture during a golf swing is acquired using a camera, and the user directly analyzes the acquired image to correct the posture on his / her own (for example, the user directly analyzes the image of his / her posture at the time of impact to check the height difference between the two shoulders and correct it on his / her own). However, according to this prior art, there was a problem in that accurate posture correction was difficult because the user had to directly find the section of the golf swing to be corrected or the body part to be corrected in the image of his / her posture.

[0005] Accordingly, the inventor(s) of the present invention propose a technology that enables a user to easily correct his / her posture and further improve his / her golf skills by obtaining a first image of a user's golf swing, determining a second image of a golf swing of a comparison target, and calculating a similarity between the user's posture and the posture of the comparison target by comparing the first image and the second image.

[0006] The purpose of the present invention is to solve all of the problems of the above-mentioned prior art.

[0007] In addition, the present invention has another purpose of obtaining a first image of a user's golf swing, determining a second image of a golf swing of a comparison target, and calculating a similarity between the user's posture and the posture of the comparison target by comparing the first image and the second image.

[0008] In addition, another purpose of the present invention is to enable a user to correct his / her posture by calculating the similarity between the user's posture and the posture of a comparison target.

[0009] In addition, another object of the present invention is to provide a user experience similar to that of a user correcting his / her posture while looking in a mirror by displaying a second image of a comparison target's posture corresponding to the user's posture in real time.

[0010] A representative configuration of the present invention to achieve the above purpose is as follows.

[0011] According to one aspect of the present invention, a method is provided, comprising the steps of: obtaining a first image of a user's golf swing, determining a second image of a golf swing of a comparison target, and comparing the first image and the second image to calculate a similarity between the posture of the user and the posture of the comparison target.

[0012] According to another aspect of the present invention, a system is provided, including an image management unit that obtains a first image regarding a user's golf swing and determines a second image regarding a golf swing of a comparison target, and a similarity calculation unit that compares the first image and the second image to calculate a similarity between the posture of the user and the posture of the comparison target.

[0013] In addition, a non-transitory computer-readable recording medium recording another method for implementing the present invention, another system, and a computer program for executing the method are further provided.

[0014] According to the present invention, a first image regarding a user's golf swing is acquired, a second image regarding a golf swing of a comparison target is determined, and the similarity between the user's posture and the posture of the comparison target is calculated by comparing the first image and the second image.

[0015] In addition, according to the present invention, by calculating the similarity between the user's posture and the posture of the comparison target, the user can correct his / her posture on his / her own.

[0016] In addition, according to the present invention, by displaying in real time a second image of a comparison target's posture corresponding to the user's posture, it is possible to provide a user experience similar to a user correcting their posture while looking in a mirror.

[0023] Composition of the entire system

[0024] FIG. 1 is a diagram schematically illustrating the configuration of an entire system for displaying information about a golf swing according to one embodiment of the present invention.

[0025] As illustrated in FIG. 1, the entire system according to one embodiment of the present invention may include a communication network (100), an information management system (200), and a device (300).

[0026] First, the communication network (100) according to one embodiment of the present invention can be configured regardless of the communication mode such as wired communication or wireless communication, and can be configured with various communication networks such as a local area network (LAN), a metropolitan area network (MAN), and a wide area network (WAN). Preferably, the communication network (100) referred to herein may be the well-known Internet or the World Wide Web (WWW). However, the communication network (100) is not necessarily limited thereto, and may include at least a portion of a well-known wired or wireless data communication network, a well-known telephone network, or a well-known wired or wireless television communication network.

[0027] For example, the communication network (100) may be a wireless data communication network that implements conventional communication methods such as WiFi communication, WiFi-Direct communication, Long Term Evolution (LTE) communication, 5G communication, Bluetooth communication (including Bluetooth Low Energy (BLE) communication), infrared communication, ultrasonic communication, etc., at least in part. As another example, the communication network (100) may be an optical communication network that implements conventional communication methods such as LiFi (Light Fidelity), etc., at least in part.

[0028] Next, the information management system (200) according to one embodiment of the present invention can perform a function of obtaining a first image regarding a user's golf swing, determining a second image regarding a golf swing of a comparison target, and calculating a similarity between the user's posture and the posture of the comparison target by comparing the first image and the second image.

[0029] The configuration and function of the information management system (200) according to the present invention will be described in detail below.

[0030] Next, a device (300) according to one embodiment of the present invention is a digital device that includes a function to communicate after connecting to an information management 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.

[0031] 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 information management system (200). Such an application may be downloaded from the information management system (200) or an external application distribution server (not shown). Meanwhile, the characteristics of such an application may be generally similar to the image management unit (210), similarity calculation unit (220), information display unit (not shown), communication unit (230), and control unit (240) of the information management system (200), which will be described later. Here, at least a portion 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.

[0032] Structure of information management system

[0033] Below, the internal configuration and functions of each component of the information management system (200) that performs important functions for implementing the present invention will be examined.

[0034] FIG. 2 is a drawing showing in detail the internal configuration of an information management system (200) according to one embodiment of the present invention.

[0035] As illustrated in FIG. 2, an information management system (200) according to one embodiment of the present invention may be configured to include an image management unit (210), a similarity calculation unit (220), a communication unit (230), and a control unit (240), and in some cases, may further include an information display unit (not shown). According to one embodiment of the present invention, at least some of the image management unit (210), the similarity calculation unit (220), the information display unit, 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 information management 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 also be stored in a remote memory device capable of communicating with the information management 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, as described later in accordance with the present invention.

[0036] Meanwhile, although the information management 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 information management system (200) may be realized within a device (300) or a server (not shown) or included within an external system (not shown) as needed.

[0037] First, the image management unit (210) according to one embodiment of the present invention can perform a function of obtaining a first image regarding a user's golf swing and determining a second image regarding a golf swing of a comparison target.

[0038] Specifically, the first image according to one embodiment of the present invention may include an image related to a user's golf swing. Here, the image management unit (210) according to one embodiment of the present invention may obtain the first image related to the user's golf swing from at least one image sensor. In addition, the at least one image sensor according to one embodiment of the present invention may be provided in a device, for example, a golf launch monitor, but is not limited thereto. In addition, the first image according to one embodiment of the present invention may be obtained by a sensor other than the image sensor (for example, a pressure distribution image obtained from a pressure sensor or a radar image obtained from a radar sensor), or may be obtained from a database included in the information management system (200), an external system, or a golf swing database (not shown).

[0039] In addition, the second image according to one embodiment of the present invention may include an image related to a golf swing of the comparison target. Here, the image management unit (210) according to one embodiment of the present invention may determine the second image from among at least one image related to a golf swing included in (or stored in) a database included in the information management system (200), an external system, or a golf swing database (not shown). In addition, the second image according to one embodiment of the present invention may include various images related to a golf swing of the comparison target, such as an image related to a golf swing performed by a user in the past, an image related to a golf swing of a professional golfer, and the present invention is not limited to the examples described above. Meanwhile, the first image and the second image according to one embodiment of the present invention may mean a static image or a dynamic image including a plurality of frames.

[0040] For example, the image management unit (210) according to one embodiment of the present invention can determine a second image from among images related to at least one golf swing.

[0041] For example, the image management unit (210) according to one embodiment of the present invention may compare a first image with at least one image related to a golf swing (e.g., images of golf swings of multiple professional golfers), and determine an image related to a golf swing whose similarity with the user's posture is calculated to be greater than a reference value as a second image. Here, according to one embodiment of the present invention, the similarity may be calculated in a manner identical to or similar to the similarity calculated by comparing the first image and the second image, which will be described later, but is not limited thereto.

[0042] For another example, according to one embodiment of the present invention, the comparison target may be determined based on a user's input. In other words, the image management unit (210) according to one embodiment of the present invention may determine the comparison target based on the user's input and determine an image of the golf swing of the comparison target as the second image.

[0043] For example, according to one embodiment of the present invention, a user may select (or input) an image of a specific golf swing (e.g., an image of a golf swing of a preferred professional golfer) from among at least one image of a golf swing. Here, the image management unit (210) according to one embodiment of the present invention may determine a second image based on the user's selection (or input).

[0044] Continuing to explain, the image management unit (210) according to one embodiment of the present invention can determine a first section to be corrected among at least one section of the user's golf swing.

[0045] Specifically, the first section according to one embodiment of the present invention may refer to a section to be corrected among eight sections of address, take away, back swing, top of swing, down swing, impact, follow through, and finish. However, the sections related to the golf swing are not limited to the eight sections described above, and may be variously changed within a range that can achieve the purpose of the present invention. For example, the first section according to one embodiment of the present invention may refer to a specific point in time (for example, the point of impact) to be corrected. That is, the first section according to one embodiment of the present invention does not necessarily refer to a section having a predetermined length of time, but may refer to a specific point in time.

[0046] For example, the image management unit (210) according to one embodiment of the present invention can determine the first section based on the section-by-section similarity between the user's posture and the posture of the comparison target calculated by the similarity calculation unit (220) described later.

[0047] For example, according to one embodiment of the present invention, similarity can be calculated by comparing the first image and the second image for each at least one section related to a golf swing. Here, the image management unit (210) according to one embodiment of the present invention can determine a section in which the calculated similarity is below a reference value as the first section.

[0048] Therefore, according to the present invention, among at least one section of a golf swing, a section in which the similarity between the user's posture and the posture of the comparison target is low (e.g., the difference between the two postures is large) can be determined as the first section, so that the first section to be corrected can be appropriately determined.

[0049] For another example, the first section according to one embodiment of the present invention may be determined based on a user's input. In other words, the image management unit (210) according to one embodiment of the present invention may determine the first section based on the user's input.

[0050] For example, according to one embodiment of the present invention, a user may select (or input) a specific section (e.g., an address section). Here, the image management unit (210) according to one embodiment of the present invention may determine a first section based on the user's selection (or input).

[0051] In addition, the image management unit (210) according to one embodiment of the present invention can estimate at least one section of a golf swing corresponding to the user's current posture based on the first image, and determine the estimated at least one section as the first section.

[0052] For example, the image management unit (210) according to one embodiment of the present invention can estimate at least one section of a golf swing corresponding to the user's current posture based on first body part information (e.g., first joint information) extracted from the first image.

[0053] For example, the image management unit (210) according to one embodiment of the present invention may acquire a first image in real time (or at predetermined intervals) and estimate at least one section (e.g., a backswing section) of a golf swing corresponding to the user's current posture based on first body part information extracted from the first image. Here, the image management unit (210) according to one embodiment of the present invention may determine the estimated at least one section as the first section.

[0054] Accordingly, according to the present invention, a section corresponding to the user's current posture can be determined as a first section, and a similarity in the first section can be calculated as described below.

[0055] Next, the similarity calculation unit (220) according to one embodiment of the present invention can perform a function of calculating the similarity between the user's posture and the posture of the comparison target by comparing the first image and the second image.

[0056] Specifically, the similarity according to one embodiment of the present invention may include a similarity by body part calculated by comparing first body part information extracted from a first image with second body part information extracted from a second image. In other words, the similarity calculation unit (220) according to one embodiment of the present invention may calculate the similarity by body part by comparing first body part information extracted from a first image with second body part information extracted from a second image. Here, the first body part information according to one embodiment of the present invention may include first joint information regarding the joint position of the user, and the second body part information may include second joint information regarding the joint position of the comparison target. In addition, the similarity by body part according to one embodiment of the present invention may be calculated based on the positional relationship between two or more body parts (for example, two or more joints), but is not limited thereto, and the similarity by body part may be calculated in various ways within a scope that can achieve the purpose of the present invention.

[0057] Additionally, the similarity according to one embodiment of the present invention may include a section-wise similarity calculated by comparing the first image and the second image for each at least one section related to a golf swing. In other words, the similarity calculation unit (220) according to one embodiment of the present invention may calculate a section-wise similarity by comparing the first image and the second image for each at least one section related to a golf swing.

[0058] For example, the similarity calculation unit (220) according to one embodiment of the present invention divides the first image and the second image into at least one section (e.g., an address section and a backswing section) related to a golf swing, and compares the first image and the second image for each of the divided at least one sections, thereby calculating the similarity for each section (e.g., the similarity in the address section is calculated as 0.8, and the similarity in the backswing section is calculated as 0.6).

[0059] For another example, the similarity calculation unit (220) according to one embodiment of the present invention may calculate body part similarity by dividing the first image and the second image into at least one section related to a golf swing, extracting body part information for each first section from the first image for each at least one section, extracting body part information for each second section from the second image for each at least one section, and comparing the body part information for each first section with the body part information for each second section.

[0060] As another example, the similarity calculation unit (220) according to one embodiment of the present invention can calculate the similarity between the posture of the user and the posture of the comparison target by comparing a first section image corresponding to a first section of a first image with a second section image corresponding to the first section of a second image.

[0061] For example, a situation may be assumed in which the first section according to one embodiment of the present invention is determined to be a backswing section. Here, the first section image according to one embodiment of the present invention may include an image of the user's golf swing in the backswing section among the first images, and the second section image may include an image of the golf swing of the comparison target in the backswing section among the second images.

[0062] Therefore, according to the present invention, as the similarity of the section to be corrected (i.e., the first section) is calculated, the user can correct his / her own posture.

[0063] As another example, the similarity calculation unit (220) according to one embodiment of the present invention can calculate the similarity between the user's posture and the posture of the comparison target by comparing the first section image and the second section image, which respectively correspond to the first section, when at least one section of the golf swing corresponding to the user's current posture is estimated and the corresponding section is determined as the first section. Accordingly, according to the present invention, the user can check his / her posture in real time (or at predetermined time intervals) and correct the posture.

[0064] Meanwhile, the information management system (200) according to one embodiment of the present invention may further include an information display unit (not shown).

[0065] An information display unit according to one embodiment of the present invention can perform a function of displaying at least one of a first image, a second image, and similarity.

[0066] Specifically, the information display unit according to one embodiment of the present invention may display at least one of a first image, a second image, and similarity (e.g., similarity by section, similarity by body part, and similarity by body part by section) through a display. Here, the display according to one embodiment of the present invention may be provided in the device (300) or a separate display device, but is not limited thereto. In addition, the information display unit according to one embodiment of the present invention may display at least one of the first section image and the second section image.

[0067] Additionally, the information display unit according to one embodiment of the present invention can display the second section image by reducing or increasing the section length so that the section length of the second section image matches the section length of the first section image.

[0068] For example, according to one embodiment of the present invention, it can be assumed that the length of the user's backswing section is 0.8 seconds (i.e., the length of the first section image), and the length of the backswing section of the comparison target is 1.0 second (i.e., the length of the second section image). Here, according to one embodiment of the present invention, when the first section image and the second section image are simply displayed, the display of the second section image may continue (i.e., the second section image may be played for 0.2 seconds more) even after the display of the first section image is finished (i.e., the first section image is played completely), so the user may have difficulty in comparing the posture with the comparison target.

[0069] Accordingly, the information display unit according to one embodiment of the present invention may display the second interval image by increasing the interval length of the second interval image (for example, by playing the second interval image slowly) so that the interval length of the second interval image matches the interval length of the first interval image, when the interval length of the second interval image (for example, 0.8 seconds) is shorter than the interval length of the first interval image (for example, by playing the second interval image slowly). Conversely, the information display unit according to one embodiment of the present invention may display the second interval image by reducing the interval length of the second interval image (for example, by playing the second interval image quickly) so that the interval length of the second interval image matches the interval length of the first interval image, when the interval length of the second interval image is longer than the interval length of the first interval image.

[0070] Therefore, according to the present invention, by displaying the second section image by increasing or decreasing the section length, the user can easily compare the posture with the comparison target.

[0071] Meanwhile, the information display unit according to one embodiment of the present invention may display an image related to the entire golf swing (i.e., the second image) by enlarging or reducing it, rather than the section image to be compared (i.e., the second section image). In other words, the information display unit according to one embodiment of the present invention may display the second image by enlarging or reducing its length so that the length of the second image matches the length of the first image.

[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 image management unit (210), the similarity calculation unit (220), and the information display unit (not shown).

[0073] Finally, the control unit (240) according to one embodiment of the present invention can perform a function of controlling the flow of data between the image management unit (210), the similarity calculation unit (220), the information display unit, 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 information management system (200) or the flow of data between each component of the information management system (200), thereby controlling the image management unit (210), the similarity calculation unit (220), the information display unit, and the communication unit (230) to perform their respective unique functions.

[0074] Hereinafter, the content for displaying information about a golf swing according to the present invention will be described in detail with reference to FIGS. 3 and 4.

[0075] FIG. 3 is a drawing exemplarily showing a golf swing of a user and a golf swing of a comparison target according to one embodiment of the present invention, and FIG. 4 is a drawing exemplarily showing a situation in which an information display unit according to one embodiment of the present invention displays a first image, a second image, and a similarity.

[0076] Example 1

[0077] According to one embodiment of the present invention, the image management unit (210) can obtain a first image regarding a user's golf swing and determine a second image regarding a golf swing of a comparison target.

[0078] And, referring to FIG. 3, the similarity calculation unit (220) can calculate the similarity between the posture of the user (410) and the posture of the comparison target (420) by comparing the first image and the second image.

[0079] Here, referring to FIG. 3, the image management unit (210) can obtain the first image in real time, and the similarity calculation unit (220) can compare the first image and the second image obtained in real time to calculate the similarity between the posture of the user (410) and the posture of the comparison target (420) in real time.

[0080] And, referring to FIG. 3, the information display unit can display a second image (or a specific frame among the second images) corresponding to the first image acquired in real time.

[0081] Therefore, according to the present invention, by displaying in real time a second image of a posture of a comparison target corresponding to the user's posture, it is possible to provide a user experience similar to a user correcting their posture while looking in a mirror.

[0082] Second Example

[0083] According to one embodiment of the present invention, the image management unit (210) can obtain a first image.

[0084] Next, the similarity calculation unit (220) can calculate the similarity by comparing each image related to at least one golf swing included (or stored) in a database included in the information management system (200), an external system, or a golf swing database (not shown) with the first image.

[0085] Next, the image management unit (210) can determine, among the images of at least one golf swing for which similarity is calculated, an image of a golf swing having a similarity higher than a standard value (or having the highest similarity), as the second image.

[0086] The posture of a professional golfer's golf swing varies widely, and the posture appropriate for a particular user may vary from user to user. According to the present invention, an image of a professional golfer's golf swing that suits the user can be determined as a second image, thereby maximizing improvement in golf skills.

[0087] Third Example

[0088] According to one embodiment of the present invention, the similarity calculation unit (220) can calculate the similarity for each section by comparing the first image and the second image for each at least one section of the golf swing (for example, the similarity is calculated as 0.5 for the backswing section, 0.7 for the downswing section, and 0.9 for the impact section).

[0089] Next, the image management unit (210) can determine the section in which the calculated section similarity is lower than or equal to a reference value (or the section with the lowest similarity) as the first section (for example, since the backswing section has the lowest similarity, the backswing section can be determined as the first section).

[0090] Therefore, according to the present invention, the first section to be corrected can be appropriately determined.

[0091] Example 4

[0092] An information display unit according to one embodiment of the present invention can display at least one of the first image, the second image, and the similarity.

[0093] Specifically, referring to FIG. 4, the information display unit may display at least one of a first image regarding a golf swing of a user (410), a second image regarding a golf swing of a comparison target (420), similarity by section (221), and similarity by body part (222).

[0094] And, referring to FIG. 4, the information display unit can display a first image in a first area on the display, a second image in a second area, section-wise similarity (221) in a third area, and body part-wise similarity (222) in a fourth area.

[0095] And, referring to FIG. 4, the information display unit can display the similarity (222) of each body part in the fourth area in order from the body part with the highest similarity.

[0096] And, referring to FIG. 4, the information display unit can display the similarity (221) by section in a time series in the form of a graph in the third area.

[0097] Therefore, according to the present invention, a user can easily understand the similarity by body part and similarity by section, and further, can efficiently correct his / her posture.

[0098] However, the form in which the information display unit according to FIG. 4 displays the first image, the second image, and the similarity is merely an example, and those skilled in the art can make various modifications from the form of FIG. 4.

[0099] The embodiments of the present invention described above may be implemented in the form of program commands that can be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, etc., either singly or in combination. The program commands recorded on the computer-readable recording medium may be specially designed and configured for the present invention or may be known and available to those skilled in the art of computer software.
