Description

Technical Field

[0001] The present invention relates to a method, a system, and a non-transitory computer-readable recording medium for providing ball quality information regarding a golf ball.

Background Art

[0002] Recently, as the development of digital technology has increased the leisure time of modern people in their daily lives, the number of people choosing golf as a hobby and sports activity has been rapidly increasing. Along with this, the domestic and international golf industries have been steadily growing, and at the center of this is a screen golf system that enables golfers to virtually enjoy golf at low cost in the city center and improve their golf skills. Such a screen golf system can have as its basic concept the acquisition of a large number of images of a golf ball when a golfer strikes the golf ball, the measurement of physical quantities regarding the golf ball based on its trajectory, interval, size, etc., and the display of the simulation result of a golf shot on a screen by performing a simulation based on this.

[0003] On the other hand, as the market scale of the golf industry has gradually expanded, a large number of domestic and international companies have participated in the golf industry market and a competitive landscape has been formed. Along with this, changes have also occurred in the needs of users of the screen golf system, and beyond simply being able to enjoy golf indoors, the need for more accurate and sophisticated sensors and a sense of presence and reality like an outdoor golf course has been expanding. That is, the actual situation is that various user interfaces or user experience elements that can further improve the immersion of users in screen golf are being demanded.

[0004] Therefore, in order to enhance the immersion of users using screen golf, many studies and attempts have been made to improve sensory interaction with the user. However, while the technologies introduced so far in relation to virtual golf simulations use various visual effects to realistically represent the ball's trajectory and advanced sensors or algorithms to accurately measure physical quantities related to the ball, there are limitations in that they are insufficient to intuitively provide users with specific shot data, such as the speed and direction of the ball after it is struck, based on the point of impact and the direction, angle, or speed of the golf club. Specifically, in the simulation system, when the ball's trajectory is represented, the focus is only on the parabola in which the ball flies, and there is a limitation that the launch angle and direction angle of the ball in the section where the ball temporarily rises (for example, the rising zone) cannot be intuitively confirmed.

[0005] Therefore, the present inventors propose a technology that improves the user's immersion and golf skills by visualizing ball impact information and directional information generated by referencing information on the physical quantities of the ball measured or estimated from at least one swing, and displaying it in a first or second area. This allows the user to immediately confirm whether the ball they hit was within the rising zone and distinguish between normal and erroneous trajectories. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Korean Registered Patent Publication No. 10-2235460 (2021.04.02) [Overview of the project] [Problems that the invention aims to solve]

[0007] The purpose of this invention is to solve all of the problems of the prior art described above.

[0008] Furthermore, the present invention also aims to improve user immersion and golf skills by providing a user interface or user experience that intuitively visualizes the correlation of information generated before the struck ball forms its trajectory, thereby enabling the user to recognize the normal and erroneous trajectories of golf shots.

[0009] Furthermore, the present invention aims to enable users to intuitively grasp cumulative data about their golf shots by displaying multiple graphic objects generated from multiple swings chronologically or cumulatively within a single frame, and to enable them to set golf shot goals and improve their golf shots based on this data.

[0010] Furthermore, another objective of the present invention is to improve the user interface or user experience so that the speed and direction of travel of a struck ball can be concretely and intuitively understood based on the point of impact and the direction, angle, or speed of the golf club. [Means for solving the problem]

[0011] A typical configuration of the present invention for achieving the above objective is as follows:

[0012] According to one aspect of the present invention, a method is provided for providing ball quality information relating to a golf ball, comprising the steps of: generating ball impact information and directional information by referring to information on physical quantities of the ball measured or estimated from at least one swing; and visualizing the generated ball impact information and directional information and displaying it in a first or second area.

[0013] According to another aspect of the present invention, a system is provided for providing ball quality information relating to a golf ball, comprising: an information generation unit that generates ball impact information and direction information by referring to information on physical quantities of the ball measured or estimated from at least one swing; and an information display unit that visualizes the generated ball impact information and direction information and displays it in a first or second area.

[0014] In addition, other methods, other systems, and non-transient, computer-readable recording media for recording computer programs for carrying out the present invention are further provided. [Effects of the Invention]

[0015] According to the present invention, by intuitively visualizing the correlation of information generated before the struck ball forms its trajectory and providing a user interface or user experience, it becomes possible to improve the user's immersion and golf skills by enabling the user to recognize the normal and erroneous trajectories of golf shots.

[0016] Furthermore, according to the present invention, by displaying multiple graphic objects generated from multiple swings chronologically or cumulatively within a single frame, the user can intuitively grasp cumulative data about their golf shots, and based on this, set goals for their golf shots and improve their golf shots.

[0017] Furthermore, according to the present invention, the psychological anxiety that arises from the fact that error trajectories generated in a virtual golf simulation system do not directly affect the score can be eliminated, and the perception of normal trajectories and error trajectories can be enhanced.

[0018] Furthermore, according to the present invention, by improving the user interface or user experience, it becomes possible to concretely and intuitively understand the speed and direction of travel of the struck ball based on the point where the ball was struck and the direction, angle, or speed of the golf club.

[0027] Configuration of the information provision system

[0028] Figure 1 is a diagram illustrating in detail the internal configuration of an information provision system 100 according to one embodiment of the present invention.

[0029] As shown in Figure 1, an information provision system 100 according to one embodiment of the present invention may be configured to include an information generation unit 110, an information display unit 120, a communication unit 130, and a control unit 140. According to one embodiment of the present invention, at least a part of the information generation unit 110, the information display unit 120, the communication unit 130, and the control unit 140 may be program modules that communicate with an external system (not shown). Such program modules may be included in the information provision system 100 in the form of an operating system, an application program module, or other program module, and may be physically stored in a variety of known storage devices. Alternatively, such program modules may be stored in a remote storage device that can communicate with the information provision system 100. On the other hand, such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc., that perform specific tasks or perform specific abstract data types as described later in the present invention.

[0030] On the other hand, although the information provision system 100 has been described as above, this description is illustrative, and it is obvious to those skilled in the art that at least some of the components or functions of the information provision system 100 may be embodied in or included in a known virtual golf simulation system as needed. Furthermore, in some cases, all the functions and components of the information provision system 100 may be performed or included entirely within the virtual golf simulation system 200.

[0031] First, the information generation unit 110 according to one embodiment of the present invention can measure or estimate information regarding the physical quantities of the ball from at least one swing. Here, the information regarding the physical quantities according to one embodiment of the present invention may mean information obtained from at least one module (for example, the direction of the body or head, the direction of the eyes, the launch angle, the lateral angle, the point (or impact point) related to the ball's strike, the time of impact, backspin, sidespin, ball speed, club speed, club direction, ball rotation, impact amount, club path, etc.). However, the information regarding the physical quantities according to one embodiment of the present invention is not limited to those listed above and can be varied in various ways within the scope that can achieve the objectives of the present invention.

[0032] For example, the information generation unit 110 according to one embodiment of the present invention can detect multiple dimples in each of multiple images of a ball that is the object of measurement or measurement. Consequently, the information generation unit 110 according to one embodiment of the present invention can measure or estimate a physical quantity related to the rotation of the ball by referring to the relationships between the attributes of the multiple dimples detected from the first image and the attributes of the multiple dimples detected from the second image.

[0033] On the other hand, for further details regarding the measurement or estimation of physical quantities, one can refer to the description in the patent application specification originally attached to Korean Patent Application No. 10-2020-0133813 filed by the present applicant, and it should be made clear that the contents described in the patent application specification of Korean Patent Application No. 10-2020-0133813 should be considered as being incorporated into this specification as a whole.

[0034] Next, the information generation unit 110 can generate ball impact information and direction information by referring to the information regarding the physical quantities.

[0035] Specifically, the ball impact information according to one embodiment of the present invention is information about the ball impact that can be measured or estimated from the user's swing, and may include information about the point of impact or the club's face angle. The club's face angle according to one embodiment of the present invention is the angle between a virtual line perpendicular to the target line and the club face, and may influence the direction of the ball after impact.

[0036] Furthermore, the ball direction information according to one embodiment of the present invention is information relating to the direction of the ball that can be measured or estimated from the user's swing, and may include information relating to the launch angle, which is related to the distance the ball travels, and the side angle, which is related to the direction in which the ball travels.

[0037] Next, the information display unit 120 according to one embodiment of the present invention can visualize the hit information and direction information of the generated ball and display it in the first or second area.

[0038] In one embodiment of the present invention, the first region may mean a frame or zone through which the ball is expected to pass after a predetermined time has elapsed from the time the ball is struck. Preferably, the predetermined time may mean the time elapsed from the time the ball is struck until the ball's trajectory (or ball shape) is formed.

[0039] Specifically, the first region according to one embodiment of the present invention may mean a region divided into four parts based on the launch angle related to the ball's reach and the lateral angle related to the ball's direction of travel.

[0040] More specifically, in one embodiment of the present invention, the horizontal axis of the first region relates to the lateral angle and may be formed to show a range of -10° to 10° from left to right, and the vertical axis of the first region in one embodiment of the present invention relates to the firing angle and may be formed to show a range of 10° to 20° from bottom to top, so that the first region can be divided into four parts based on the midpoint of the horizontal and vertical axes. Furthermore, according to one embodiment of the present invention, the range of the horizontal or vertical axis representing the first region can be dynamically changed based on the user's operation or selection.

[0041] On the other hand, the second region according to one embodiment of the present invention may mean a set of regions that can show information related to velocity among the hit information and directional information of the generated ball.

[0042] Specifically, the second region according to one embodiment of the present invention may represent a spectrum (for example, a set of line segments representing colors, continuously connected from red on the left to green on the right) representing the speed of the ball or club head measured or estimated from the user's swing.

[0043] Furthermore, a second region according to one embodiment of the present invention may include a region in which the ball speed or clubhead speed measured or estimated from the user's swing can be displayed along with at least one reference speed interval. In one embodiment of the present invention, the reference speed interval may mean an interval for determining whether the ball speed or clubhead speed measured or estimated from the user's swing is appropriate.

[0044] More specifically, a second region according to one embodiment of the present invention is a spectrum extending from red to green, where the ball speed or clubhead speed measured or estimated from the user's swing can be displayed within the spectrum in the form of a second graphic object (e.g., a bar or line segment), as described later.

[0045] Furthermore, according to one embodiment of the present invention, the reference speed range is included in the green area, and when the second graphic object is within the reference speed range, the user can recognize that they have made an appropriate swing (for example, swinging with an appropriate club head speed or swinging so that the ball speed is appropriate), and when the second graphic object is in the red area outside the reference speed range, the user can recognize that they have made an inappropriate swing (for example, swinging with an inappropriate club head speed or swinging so that the ball speed is inappropriate).

[0046] On the other hand, the information display unit 120 according to one embodiment of the present invention can generate a graphic object by referring to ball impact information and direction information.

[0047] Specifically, the graphic object according to one embodiment of the present invention may represent geometric information that can be displayed as a point, line, or surface in relation to the ball's impact information and directional information.

[0048] More specifically, a graphic object according to one embodiment of the present invention may include a first graphic object displayed in a first area in which the shape of the ball, the point of impact of the ball, and the face angle are represented in the form of points, lines, or surfaces, and a second graphic object displayed in a second area in which the ball speed or clubhead speed measured or estimated from the user's swing is represented in the form of a rod or line segment.

[0049] Furthermore, the first graphic object generated according to one embodiment of the present invention may be displayed in the first region at a position that takes into account the firing angle and lateral angle.

[0050] More specifically, a first graphic object according to one embodiment of the present invention is an object in which the shape of a ball, a point related to the ball's impact, and a face angle are represented in the form of a point, line, or plane, and can be displayed in a position in a first area after the ball has been struck and before the ball's trajectory (or ball flight) is formed, taking into account the launch angle and lateral angle determined based on the relationship between the point related to the ball's impact, the face angle, the ball's velocity, or the club head's velocity.

[0051] Furthermore, according to one embodiment of the present invention, multiple first graphic objects generated from multiple swings of the user can be cumulatively displayed in the first area.

[0052] Specifically, a plurality of first graphic objects generated by one embodiment of the present invention may be displayed in a chronological order. For example, the plurality of first graphic objects may be displayed with different colors or shapes depending on the order in which they were generated.

[0053] According to yet another embodiment of the present invention, a plurality of first graphic objects displayed in a first area through a first golf simulation (for example, when the user performs screen golf rounding at time t) can be displayed or removed in the first area based on the user's operation or selection when the user performs a second golf simulation (for example, when the user performs screen golf rounding at time t+1).

[0054] Through this, users can improve their golf skills by updating their unique primary domain and improving the accuracy of their shots.

[0055] Next, the communication unit 130 according to one embodiment of the present invention can perform the function of enabling the transmission and reception of data to and from the information generation unit 110 and the information display unit 120.

[0056] Finally, the control unit 140 according to one embodiment of the present invention can perform the function of controlling the flow of data between the information generation unit 110, the information display unit 120, and the communication unit 130. That is, the control unit 140 according to one embodiment of the present invention can control the flow of data from and to the information provision system 100 or the flow of data between each component of the information provision system 100 so that the information generation unit 110, the information display unit 120, and the communication unit 130 each perform their respective functions.

[0057] Figure 2 is a diagram illustrating, in an example, how the information provision system 100 according to the present invention is utilized in a virtual golf simulation system 200 according to one embodiment of the present invention.

[0058] As shown in Figure 2, the virtual golf simulation system 200 may be configured to include a hitting unit 10, a lighting device 20, a shooting device 210, a simulator 220, and a display device 230. Furthermore, the simulator 220 according to one embodiment of the present invention may include the information provision system 100 according to the present invention.

[0059] First, one embodiment of the present invention may be a striking section 10 on which a golfer places their feet, stands, and places a golf ball when using a virtual golf simulation system 200. Such a striking section 10 may include a known swing plate whose inclination angle can be adjusted. Incidentally, when the present invention is applied to other types of virtual sports simulator systems, those skilled in the art can appropriately modify the configuration of the striking section 10, along with the configuration of other components that work together with it, as necessary, to suit the characteristics of the sport in question.

[0060] Next, a lighting device 20 according to one embodiment of the present invention may be a device that can artificially illuminate a golfer when they are enjoying virtual golf indoors or outdoors. Such a lighting device 20 can be turned on and off as needed, and its brightness can be adjusted. Preferably, the lighting device 20 may be infrared lighting (e.g., LED lighting) to prevent the natural degradation of multiple images due to light blinking.

[0061] Next, the imaging device 210 according to one embodiment of the present invention can perform the function of acquiring multiple images relating to ball impact information and directional information, including at least one module (e.g., an eye-tracking camera module, a swing motion camera module, a sensing module, etc.) (not shown). Such an imaging device 210 may be positioned to look down on a moving golf club head from above, but it may be positioned in other locations. On the other hand, the imaging device 210 according to one embodiment of the present invention can achieve performance similar to a high-speed camera by sequentially acquiring multiple images using at least two cameras with different imaging speeds, or it can achieve performance similar to a three-dimensional camera by simultaneously acquiring multiple images using two two-dimensional cameras.

[0062] Next, the simulator 220 according to one embodiment of the present invention can perform the function of providing the user with information (for example, a graphic object generated by referencing ball impact information and the directional information) obtained by combining or analyzing information transmitted from an eye-tracking camera module, a swing motion camera module, or a sensing module, including a main module. On the other hand, the simulator 220 according to one embodiment of the present invention can communicate with a shooting device 210 and a display device 230, and may include a dedicated processor for the virtual golf simulation system 200. Such a dedicated processor may be equipped with memory means and have numerical computation capabilities and graphics processing capabilities.

[0063] Finally, a display device 230 according to one embodiment of the present invention can perform the function of visualizing and displaying information obtained from the analysis of the simulator 220. Such a display device 230 can display a predetermined image through a predetermined display means, which may consist of, for example, a screen that absorbs the impact of a golf ball being struck but does not emit light directly, and a projector that outputs an image to such a screen.

[0064] Figure 3 is a diagram illustrating the first and second regions provided by a virtual golf simulation system 200 according to one embodiment of the present invention.

[0065] According to Figure 3, the first region 301 in one embodiment of the present invention may represent a frame composed of a vertical axis relating to the launch angle and a horizontal axis relating to the lateral angle, divided into four sections with respect to the center. Furthermore, the second region 302 in one embodiment of the present invention may represent a spectrum representing the speed of the ball or the speed of the club head, and may be displayed together with a reference speed section 303 that can be used to determine whether the speed of the ball or the speed of the club head is appropriate.

[0066] Figures 4 to 6 are illustrative diagrams illustrating a situation in which a user interface or user experience providing information about a golf ball is provided according to one embodiment of the present invention.

[0067] First, as shown in Figure 4, ball impact information and direction information are generated by referring to information on the physical quantities of the ball measured or estimated based on the user's first swing, and a first graphic object 403 and a second graphic object 404 may be generated based on the ball impact information and direction information.

[0068] Subsequently, the first graphic object 403 may be displayed in the first region 401 at a position that takes into account the launch angle and lateral angle, and the second graphic object 404 may be displayed in the second region 402, taking into account the speed of the ball or the speed of the club head.

[0069] Next, as shown in Figure 5, a first graphic object 502 generated based on the user's second swing may be displayed in the first area together with a first graphic object 501 generated based on the user's first swing. Here, a plurality of first graphic objects 501, 502 according to one embodiment of the present invention may be displayed in a chronological order, and for example, they may be displayed with different colors or shapes depending on the order in which they were generated.

[0070] Next, as shown in Figure 6, it can be seen that the multiple first graphic objects generated based on multiple swings of a user according to one embodiment of the present invention are displayed at other locations in the first region because the launch angle and lateral angle change depending on information about the physical quantities of the ball measured from the user's swing (e.g., the point related to the ball's impact (or impact point), face angle, club path, etc.). Specifically, the first graphic object 602 according to one embodiment of the present invention may be visualized and displayed in the first region together with the impact point and face angle.

[0071] Furthermore, a plurality of first graphic objects displayed in the first area through the first golf simulation 601 according to one embodiment of the present invention can be displayed or removed in the first area based on the user's operation or selection when the user performs a second golf simulation.

The computer-readable recording medium may include program instructions, data files, data structures, etc., individually or in combination. The program instructions recorded on the computer-readable recording medium may be specifically designed and configured for the present invention or may be available to those skilled in the art of computer software.
