[0037] Composition of the entire system

[0038] FIG. 1 is a drawing schematically showing the configuration of an entire system for performing calibration on a golf simulator screen according to one embodiment of the present invention.

[0039] As illustrated in FIG. 1, the entire system according to one embodiment of the present invention may include a communication network (100), a screen calibration system (200), and a device (300).

[0043] The configuration and function of the screen calibration system (200) according to the present invention will be described in detail below.

[0044] 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 screen calibration 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.

[0045] 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 screen calibration system (200). Such an application may be downloaded from the screen calibration system (200) or an external application distribution server (not shown). Meanwhile, the nature of such an application may be generally similar to the screen display unit (210), calibration performing unit (220), communication unit (230), and control unit (240) of the screen calibration 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.

[0046] Configuration of the screen calibration system

[0047] Below, the internal configuration and functions of each component of the screen calibration system (200) that performs important functions for implementing the present invention will be examined.

[0048] FIG. 2 is a drawing showing in detail the internal configuration of a screen calibration system (200) according to one embodiment of the present invention.

[0049] As illustrated in FIG. 2, a screen calibration system (200) according to one embodiment of the present invention may be configured to include a screen display unit (210), a calibration performing unit (220), a communication unit (230), and a control unit (240). According to one embodiment of the present invention, at least some of the screen display unit (210), the calibration performing 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 screen calibration 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 screen calibration 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.

[0050] Meanwhile, although the screen calibration 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 screen calibration system (200) may be realized within a device (300) or a server (not shown) or included within an external system (not shown) as needed.

[0051] First, the screen display unit (210) according to one embodiment of the present invention can perform a function of displaying a golf simulator screen on the display unit.

[0052] Specifically, the screen display unit (210) according to one embodiment of the present invention can perform a function of displaying a golf simulator screen on a display unit (e.g., a golf mat) by projecting the golf simulator screen onto the display unit. For example, the screen display unit (210) according to one embodiment of the present invention can project a golf simulator screen onto a golf mat by using a light source (e.g., a light source of a beam projector). However, it is obvious to those skilled in the art that the projection of the golf simulator screen according to one embodiment of the present invention can be performed in various ways other than using a beam projector.

[0053] According to one embodiment of the present invention, a golf simulator screen displayed on a display unit may include a user interface screen for calibration. Specifically, according to one embodiment of the present invention, the user interface screen may include a cursor (e.g., an arrow-shaped pointer) indicating a user's input, an icon for manipulating the golf simulator screen, and an adjustable mark (e.g., a mark including a circular shape and a rectangular shape) whose position and size are adjusted according to screen calibration. At this time, the golf simulator screen is connected to a device (300), and the user can manipulate the golf simulator screen through the device (300).

[0054] Meanwhile, the screen display unit (210) according to one embodiment of the present invention can prevent the golf simulator screen from being distorted depending on the angle at which the golf simulator screen is projected onto the display unit (e.g., golf mat) by performing keystone correction on the golf simulator screen.

[0055] Next, the calibration performing unit (220) according to one embodiment of the present invention can perform a function of performing calibration on the golf simulator screen by referring to a calibration panel disposed on the display unit and a user's input.

[0056] According to one embodiment of the present invention, a calibration panel may essentially mean an object that serves as a reference for accurate and simple screen calibration. The calibration panel may be formed in various shapes, forms, structures, etc.

[0057] Specifically, a calibration panel according to one embodiment of the present invention may include a circular shape and a rectangular outline shape surrounding the circular shape.

[0058] FIG. 3 is a drawing exemplarily illustrating a calibration panel according to one embodiment of the present invention.

[0059] Referring to FIG. 3, the calibration panel may include a circular shape at the center and a rectangular outline surrounding the circular shape at the center. In this case, according to one embodiment of the present invention, the diameter of the circular shape included in the calibration panel may be formed to be equal to the diameter of an actual golf ball.

[0060] Continuing, according to one embodiment of the present invention, a user's input may be performed via an input device (e.g., a mouse, a touch screen, etc.) of the device (300) for screen calibration. At this time, a display (e.g., a display including a circular shape and a rectangular shape) may be displayed on the golf simulator screen to assist the user in performing input in accordance with the calibration panel.

[0061] FIG. 4 is a diagram exemplarily illustrating a process in which a user performs input according to one embodiment of the present invention.

[0062] Referring to Fig. 4, a golf simulator screen is projected onto a golf mat corresponding to a display unit, and a calibration panel is placed on the golf mat. In Fig. 4, the range of the golf simulator screen is indicated by a dotted line. According to one embodiment of the present invention, since the golf simulator screen is projected onto the golf mat via a beam projector, the calibration panel on the golf mat and the golf simulator screen may appear to overlap.

[0063] According to FIG. 4, a user can perform input for screen calibration by specifying a range within a golf simulator screen using a cursor. Specifically, the user can operate the cursor within the golf simulator screen using the input device of the device (300), and the user can specify a range within the golf simulator screen by using the cursor to fit the outline shape of a rectangle included in the calibration panel. More specifically, referring to FIG. 4, for example, the user can perform input for screen calibration by specifying a rectangular range by dragging the mouse cursor from one point (StartPos) to another point (EndPos) within the golf simulator screen. In this way, the user can perform input for screen calibration simply and accurately by referring to the calibration panel.

[0064] Meanwhile, the method and type of user input according to one embodiment of the present invention are not limited to the above example.

[0065] Meanwhile, the calibration performing unit (220) according to one embodiment of the present invention may further perform a function of recognizing a calibration panel and a golf ball placed on a golf mat corresponding to the display unit. Specifically, according to one embodiment of the present invention, the calibration performing unit (220) may recognize a golf ball and a calibration panel placed on a golf mat through a sensor (e.g., an image sensor such as a camera). In this case, the objects that can be recognized and the method of recognizing the objects are not limited to the above example.

[0066] Continuing, the calibration performing unit (220) according to one embodiment of the present invention may perform a function of performing position calibration for a golf simulator screen by referring to the user's input and the position information of the calibration panel.

[0067] Specifically, the calibration performing unit (220) according to one embodiment of the present invention can perform position calibration for the golf simulator screen by adjusting the golf simulator screen so that the position of the adjusted mark can be aligned with a position within a range specified by the user within the golf simulator screen. More specifically, according to one embodiment of the present invention, the position calibration for the golf simulator screen can be performed by adjusting the golf simulator screen so that the position coordinates of the adjusted mark on the display unit can be aligned with the position coordinates within a range specified by the user within the golf simulator screen. At this time, the calibration performing unit (220) according to one embodiment of the present invention can perform accurate position calibration by recognizing the position coordinates of a calibration panel disposed on the display unit and adjusting the position coordinates within a range specified by the user within the golf simulator screen to match the position coordinates of the calibration panel.

[0068] Meanwhile, the calibration performing unit (220) according to one embodiment of the present invention can perform a function of performing size calibration for a golf simulator screen by referring to the user's input and the size information of the calibration panel.

[0069] Specifically, the calibration performing unit (220) according to one embodiment of the present invention can perform size calibration on the golf simulator screen by adjusting the golf simulator screen so that the size of the adjusted display can match the size of the range specified by the user on the golf simulator screen. More specifically, according to one embodiment of the present invention, the size calibration on the golf simulator screen can be performed by adjusting the size and ratio of the golf simulator screen so that the size of the adjusted display can match the size of the range specified by the user on the golf simulator screen. At this time, the calibration performing unit (220) according to one embodiment of the present invention can perform accurate position calibration by recognizing the size of a calibration panel arranged on the display unit and adjusting the size of the range specified by the user on the golf simulator screen to the size of the calibration panel. Specifically, the size calibration on the golf simulator screen can be performed by adjusting the size of the range specified by the user on the golf simulator screen to the calibration panel through a linear scaling or proportional scaling algorithm.

[0070] FIG. 5 is a drawing exemplarily illustrating a situation in which calibration is performed according to one embodiment of the present invention.

[0071] Referring to (a) and (b) of FIG. 5, a golf simulator screen is projected onto a golf mat corresponding to the display unit, and a calibration panel is placed on the golf mat. At this time, since the golf simulator screen is projected onto the golf mat via a beam projector, the calibration panel on the golf mat and the golf simulator screen may appear to overlap.

[0072] Fig. 5 (a) illustrates an example of a situation before calibration is performed. Specifically, Fig. 5 (a) illustrates an arrow-shaped cursor for indicating user input and an adjustment mark whose position and size are adjusted as screen calibration is performed.

[0073] FIG. 5(b) illustrates an example of performing calibration with reference to a user's input and a calibration panel. Specifically, an arrow-shaped cursor for indicating a user's input, an adjusted display whose position and size are adjusted as screen calibration is performed, and a calibration panel that appears to overlap the adjusted display are illustrated. Referring to FIG. 5(b), for example, a user may perform input for screen calibration by manipulating a cursor within a golf simulator screen through an input device (e.g., a mouse) of a device (300) to align the cursor with the calibration panel to designate a range within the golf simulator screen (e.g., by dragging the mouse cursor to designate a range). Subsequently, the calibration performing unit (220) may perform position calibration by adjusting the position of the golf simulator screen to the upper left so that the position of the adjusted display can be aligned with the position of the range specified by the user within the golf simulator screen. Subsequently, size calibration may be performed by reducing and adjusting the size of the golf simulator screen so that the size of the adjusted display can be aligned with the size of the range specified by the user within the golf simulator screen. At this time, the calibration performing unit (220) recognizes the position and size of the golf calibration and adjusts the golf simulator screen according to the position and size of the calibration, thereby performing accurate screen calibration.

[0074] That is, referring to (a) and (b) of FIG. 5, it can be confirmed that the golf simulator screen is reduced in its entirety and moved to the upper left in accordance with the golf calibration panel and user input.

[0075] Meanwhile, the golf simulator screen calibration method according to one embodiment of the present invention is not limited to the above example, and any method capable of adjusting the position and size of the screen of a golf simulator may correspond to the screen calibration method according to one embodiment of the present invention.

[0076] FIG. 6 is a drawing exemplarily showing a situation in which screen calibration is completed according to one embodiment of the present invention.

[0077] Referring to (a) and (b) of FIG. 6, a golf simulator screen is projected onto a golf mat corresponding to the display section, and a golf ball is placed on the golf mat. At this time, since the golf simulator screen is projected onto the golf mat via a beam projector, the golf ball on the golf mat and the golf simulator screen may appear to overlap.

[0078] FIG. 6 (a) shows an example of a result displayed on a golf simulator screen by recognizing a golf ball placed near the middle of a golf mat after screen calibration is completed. Meanwhile, FIG. 6 (b) shows an example of a result displayed on a golf simulator screen by recognizing a golf ball placed near the lower left side of a golf mat after calibration is completed. That is, when calibration of a golf simulator screen according to an embodiment of the present invention is completed, the calibration performing unit (220) can recognize a golf ball placed on a golf mat and display a 'READY' phrase indicating that preparation for performing a golf simulation is complete on the golf simulator screen.

[0079] Meanwhile, the calibration performing unit (220) according to one embodiment of the present invention can perform a function of rearranging the calibrated golf simulator screen based on the adjusted position and size when screen calibration is completed.

[0080] Furthermore, the calibration performing unit (220) according to one embodiment of the present invention may further perform a function to support a user to check whether screen calibration has been performed accurately.

[0081] Specifically, when the calibration performing unit (220) according to one embodiment of the present invention completes screen calibration and the user moves the calibration panel or golf ball placed on the display unit (e.g., golf mat) within the display unit, the calibration performing unit (220) according to one embodiment of the present invention can recognize the calibration panel or golf ball placed on the display unit again and visually display information about the position and size of the recognized calibration panel or golf ball on the golf simulator screen. At this time, in response to the fact that the information about the position and size of the calibration panel or golf ball displayed on the golf simulator screen does not match the actual information, the user can command the calibration performing unit (220) to perform screen calibration again. That is, the calibration performing unit (220) according to one embodiment of the present invention can continuously recognize the calibration panel or golf ball placed on the display unit and visually display information about the position and size of the calibration panel or golf ball on the golf simulator screen, thereby supporting the user to check whether the screen calibration has been performed accurately.

[0082] FIG. 7 is a drawing exemplarily showing a situation in which a calibration performing unit (220) supports a user to check whether screen calibration has been performed accurately, corresponding to a calibration panel (which may also be referred to as a 'calibration panel') being placed on a display unit according to one embodiment of the present invention.

[0083] Referring to Fig. 7, a golf simulator screen is projected onto the display unit, and a calibration panel is positioned above the display unit. At this time, since the golf simulator screen is projected onto the display unit, the calibration panel above the display unit and the golf simulator screen may appear to overlap.

[0084] Referring to FIG. 7, for example, when the user moves the calibration panel (i.e., calibrator) placed on the display unit (e.g., golf mat) after screen calibration is completed, the calibration performing unit (220) can recognize the position and size of the calibration panel placed on the display unit again. Subsequently, the calibration performing unit (220) according to one embodiment of the present invention can display, on the golf simulator screen, a mark in the shape of a rectangular outline surrounding the calibration panel on the display unit as information about the position and size of the calibration panel. At this time, the user can check whether the mark in the shape of a rectangular outline displayed on the golf simulator screen accurately surrounds the calibration panel, and if the mark in the shape of a rectangular outline does not accurately surround the calibration panel, the user can command the calibration performing unit (220) to perform screen calibration again.

[0085] FIG. 8 is a drawing exemplarily showing a situation in which a calibration performing unit (220) supports a user to check whether screen calibration has been performed accurately in response to a golf ball being placed on a display unit according to one embodiment of the present invention.

[0086] Referring to Fig. 8, a golf simulator screen is projected onto the display unit, and a golf ball is placed on the display unit. At this time, since the golf simulator screen is projected onto the display unit, the golf ball on the display unit and the golf simulator screen may appear to overlap.

[0087] Referring to FIG. 8, for example, when a user moves a golf ball placed on a display unit (e.g., a golf mat) after screen calibration is completed, the calibration performing unit (220) can recognize the position and size of the golf ball placed on the display unit again. Subsequently, the calibration performing unit (220) according to one embodiment of the present invention can display, on the golf simulator screen, a mark in the shape of an outline of a circle surrounding a golf ball on a golf mat as information about the position and size of the golf ball. At this time, the user can check whether the mark in the shape of an outline of a circle displayed on the golf simulator screen accurately surrounds the golf ball, and if the mark in the shape of an outline of a circle does not accurately surround the golf ball, the user can command the calibration performing unit (220) to perform screen calibration again.

[0088] However, according to one embodiment of the present invention, the information regarding the position and size of the calibration panel or the golf ball visually displayed on the golf simulator screen is not limited to the display of a rectangular outline shape and a circular outline shape.

[0089] 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 screen display unit (210) and the calibration performing unit (220).

[0090] 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 screen display unit (210), the calibration performing 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 screen calibration system (200) or the flow of data between each component of the screen calibration system (200), thereby controlling the screen display unit (210), the calibration performing unit (220), and the communication unit (230) to perform their respective unique functions.
