FIG. 1 is a diagram showing the schematic structure of a virtual golf device according to an embodiment of the present invention, FIG. 2 is a flowchart showing the process of an operation method applicable to the virtual golf device of FIG. 1, and FIGS. 3 to 5 are hole cups. It shows examples of various screens showing the surrounding area, and Figure 6 is a diagram showing an example of calculating the trajectory of a golf ball by reflecting the characteristics of the area around the hole cup.

Referring to FIG. 1, the virtual golf device includes a hitting plate 10, a control unit 20, a detection unit 30, an input unit 40, a sound unit 50, and a display unit 60.

The hitting plate 10 is an area where the user is positioned to hit a golf ball. Although not shown in the drawing, an auto tee that can move up and down is installed on the hitting plate 10, so that the user can use the hitting golf ball through the auto tee. The ball may be provided automatically.

The control unit 20 controls the overall operation of each component of the virtual golf device. For example, the control unit 20 can control the auto tee installed on the hitting plate 10 so that a golf ball for hitting is provided from the auto tee according to the time when the user hits. The control unit 20 includes a calculation unit 21, an image processing unit 22, a setting unit 23, and a storage unit 24. The calculation unit 21 performs a calculation operation to calculate a trajectory assuming that the golf ball flies on an actual golf course in its physical state based on the physical state of the golf ball hit by the user. The image processing unit 22 forms an image displayed on the display unit. For example, when a user selects a specific golf course, the image processing unit 22 forms an image of the specific golf course selected by the user so that the user can play on the golf course. When a user selects a play option for playing screen golf, the setting unit 23 performs a setting operation to cause the virtual golf device to operate in the selected play option. In particular, in the virtual golf device of this embodiment, the user can select and play any one of the first and second modes, and the operation of the setting unit 23 is also related to the setting process of the first and second modes. There is. The storage unit 24 stores various data necessary to perform the operations of the control unit 20, including calculation operations and setting operations.

The detection unit 30 is used to determine physical state information about the golf ball by detecting the movement of the golf club or the movement of the golf ball hit by the user when hitting the golf ball. As the detection unit 30, the golf Sensing means such as a camera or detection sensor that can capture the movement of a club or golf ball may be used. Various sensing methods such as image sensing, light emission/reception sensing, and laser sensing may be applied to the sensing means, and through these sensing methods, the movement of the golf club or the state information of the golf ball hit by the user can be determined. The cameras, detection sensors, etc. may be used alone or together, and only one unit may be used, or multiple units may be used as needed.

The input unit 40 is used to receive various information from the user, and a keyboard or mouse can be used. A login system that requires the user to log in before providing the service can be applied to screen golf, and when the login system is applied, the input unit 40 can be used when the user enters his or her ID or password. Additionally, the input unit 40 can be used in screen golf, such as when the user selects the golf course he or she wants to play or the difficulty level of play.

The sound unit 50 may include an audio device such as a speaker, and through this, guides the user to the progress of the game and plays various sound effects according to the progress of the game.

The display unit 60 includes devices such as a projector and screen. The projector projects the image of the golf course and golf ball formed by the image processing unit 22 onto the screen so that the image can be displayed on the screen, and the screen displays the projected image to show it to the user.

The virtual golf device is a device that is installed on a screen golf course to allow screen golf to be played. When a user plays screen golf, the operation process of the virtual golf device is as follows. When the user hits a golf ball, the sensor 30 detects the physical state, such as the movement of the golf club or the speed or direction of movement of the golf ball hit by the user. The information detected by the detection unit 30 is transmitted to the control unit 20, and the calculation unit 21 of the control unit 20 assumes that the user has hit a golf ball on an actual outdoor golf course based on the transmitted information. Calculate what kind of trajectory the golf ball will show at this time. The trajectory of a golf ball can be calculated only by the movement of the golf ball, or it can be calculated by taking into account the movement of the golf club at the time of hitting. When the calculation process is completed, the image processing unit 22 of the control unit 20 forms an image of a virtual golf ball (the golf ball in the screen image is called a 'virtual golf ball') moving according to the calculated trajectory, and the formed The image is displayed by the display unit 60, and at this time, the virtual golf ball flies along the calculated trajectory and then the virtual golf course in the screen (the golf course in the screen image is called 'virtual golf course') is specified. It lands at the point, and the user continues the next hit from the point where the virtual golf ball landed.

Referring to FIG. 2, the virtual golf device according to this embodiment provides the user with different play modes of the first mode and the second mode, and the user can select the desired play method, the specific process of which is as shown in the first to the second modes. It includes 5 stages (S1, S2, S3, S4, S5). In the first step (S1), the user selects a desired play method between the first mode and the second mode before playing screen golf. When the user selects the first mode, the second step (S2) is executed, and the second step (S2) can be said to be a typical normal mode. In the second step (S2), a normal image is displayed on the screen and other operations are performed similarly to the existing method, and detailed descriptions thereof will be omitted. When the user selects the second mode, the third to fifth steps (S3, S4, and S5) are executed, and the second mode can be said to be a special mode that is different from the existing mode. Specifically, in the third step (S3), the surrounding requirements around the hole cup are set, and in the fourth step (S4), in addition to the normal image, a detailed image around the hole cup with the requirements set in the third step (S3) is displayed on the screen. In the fifth step (S5), the putting trajectory of the golf ball is calculated by reflecting the surrounding requirements near the hole cup when the user puts. When selecting the second mode, all of the third to fifth steps (S3, S4, and S5) do not necessarily have to be executed, and it is possible to execute only some of them. For example, when selecting the second mode, only the fourth step (S4) among the third to fifth steps (S3, S4, and S5) may be configured to be executed.

3 to 5 show examples of screens when the fourth step (S21) is executed. Referring to Figures 3 to 5, when the second mode is selected, the area around the hole cup before putting may be enlarged and displayed in detail on the screen. As shown in FIGS. 3 and 4, when the area around the hole cup is enlarged and displayed on the screen, the state of the grass around the hole cup can be revealed in detail. There may be various conditions of the grass, but representative examples include the direction in which the grass is lying (grass texture; Figure 3) or the degree to which water droplets (WD) are formed on the grass (Figure 4). The direction in which the grass lies or the moisture condition of the grass surface can be variables that can affect the results of putting in actual golf. The grass texture or the moisture condition of the grass were overlooked because their influence on putting was relatively small compared to other variables such as the distance between the golf ball and the hole cup or the slope of the green area. However, in the virtual golf device of the present invention, the above was overlooked. The variables are displayed in detail on the screen, and the variables can be directly reflected when deriving putting results. In addition to an enlarged image of the grass in the area around the hole cup, as shown in FIG. 5, a detailed topographical outline of the area around the hole cup can be displayed on the screen. Since the final target point of putting is the hole cup, many golfers may pass by near the hole cup in actual golf. When a golfer who succeeds in putting retrieves the holed golf ball from the hole cup, or when another golfer wants to move the flagpole placed in the hole cup to a different location before the golfer putst (in actual golf, the position of the hole cup can be seen from a distance) The flagpole is placed so that you can check the hole cup, but when putting near the hole cup, you can know the location of the hole cup without the flagpole, and since the flagpole may get in the way when putting, you must temporarily move the flagpole from the hole cup to another place before putting. Due to the nature of golf play, many golfers pass by near the hole cup, such as when returning a flagpole that has been temporarily moved to another location for putting to its original location where the hole cup was after the putting. Whenever golfers pass by, fine footprints may be created, and especially when multiple people pass by, some of the footprints may overlap and the topography of the overlapped area may be deformed. This deformation may affect the putting results by irregularly changing the contour of the terrain near the hole cup. In the virtual golf device according to this embodiment, a detailed outline of the terrain near the hole cup reflecting the above deformation results is displayed on the screen. It can be. Here, the enlarged image around the hole cup can be provided in various ways, such as being displayed directly around the hole cup as shown in FIGS. 3 and 4, or displayed in a separate window in a specific area of the screen as shown in FIG. 5.

It has been explained above that in the second mode, the direction in which the grass around the hole cup lies, the moisture status of the grass surface, and the topographical contour of the area around the hole cup can be displayed through an enlarged image around the hole cup. The three matters mentioned here (the direction in which the grass lies, the moisture condition of the grass surface, and the topographical contour of the area around the hole cup) may be displayed on the screen alone, or at least some of them may be displayed together. there is. In addition, the drawings (FIGS. 3 to 5) presented to explain these three points are expressed in a very simple form for convenience of explanation, but the enlarged image around the hole cup is enough to reproduce the appearance of an actual golf course. It can be provided as a high-definition color image. For example, in actual golf, if the grass lies forward in the direction in which the golf ball rolls on a clear day, sunlight is reflected on the grass and the grass appears slightly brighter, and if the grass lies in the opposite direction to the direction in which the golf ball rolls, the grass appears slightly brighter. In this case, on the contrary, the grass may appear slightly dark, but when the enlarged image on the screen shows the direction in which the grass around the hole cup lies, even the subtle brightness and darkness of the grass can be expressed. In addition, the direction in which the grass lies, the moisture condition of the grass surface, and the topographical contour of the area around the hole cup are mentioned as a few examples. In addition to this, other details representing the characteristics around the hole cup can be displayed through an enlarged image around the hole cup. . Additionally, the enlarged image may be displayed on a screen placed in front, or, although not shown in the drawing, on a kiosk screen provided separately from the screen to provide various additional information.

3 to 5 show examples of screens when the fourth step (S4) is executed in the second mode, and in the second mode, the third step (S3) may be executed before the fourth step (S21). In the third step (S3), conditions in the area around the hole cup are set. Taking the above-mentioned three characteristics of the area around the hole cup as an example, on an actual golf course, the direction in which the grass lies/the moisture condition of the grass surface/the topographical contour of the area around the hole cup do not always remain the same and may change from time to time. The direction in which the grass lies can change slightly due to the influence of wind or precipitation, and the moisture status of the grass surface varies depending on the morning/lunch/dinner time (in the morning, there is dew and there are more water droplets, and in the afternoon, there are more water droplets due to high temperatures). may have evaporated), its condition may change due to the influence of temperature/precipitation/wind even during the same time period, and the topographical contour of the area around the hole cup may change depending on how many golfers pass around the hole cup. Therefore, when the user selects the second mode, the requirements are first set such as the direction in which the grass is lying/the moisture condition of the grass surface/the topographical contour of the area around the hole cup, etc., and then the video is imaged according to the requirements set above. An image is formed and the formed video image is displayed on the screen. Here, setting requirements such as the direction in which the grass is lying/moisture state of the grass surface/topographical contour of the area around the hole cup can be set randomly in the setting unit 23, or the user can select the requirements he or she wants. You can.

Referring to Figure 6, the characteristics of the area around the hole cup (the direction in which the grass is lying, the moisture state of the grass surface, the topographical contour of the area around the hole cup, etc.) can be reflected in calculating the trajectory of the golf ball put by the user. there is. When the characteristics of the area around the hole cup are not reflected (first mode), the trajectory shown by the virtual golf ball on the screen is called the first trajectory (T1 = S0 + S1), and when the characteristics of the area around the hole cup are reflected (second mode) mode), if the trajectory shown by the virtual golf ball on the screen is the second trajectory (T2=S0+S2), when the user putsts a real golf ball under the same conditions in the first and second modes, the putted The trajectory calculated based on the physical state of the actual golf ball can be calculated as the same trajectory (S0) until the virtual golf ball reaches the area (A) near the hole cup. However, when the virtual golf ball reaches the area (A) near the hole cup and passes through it, and the characteristics of the area around the hole cup are reflected, the first and second trajectories (T1, T2) may be different from each other.

For example, if the golf ball put by the user has an initial velocity (V0) and an initial angle (θ0) immediately after putting, the first trajectory (T1) is a golf ball with an initial velocity (V0) and an initial angle (θ0). It can be calculated by assuming what kind of trajectory it will have when rolling on an actual golf course (the actual trajectory of a golf ball is a variable representing the physical state of various other golf balls in addition to the speed and angle of the golf ball, or the golf club when putting) It can be calculated by considering the movement of , but here, for convenience of explanation, it is assumed that the golf ball's trajectory is calculated only based on speed and angle.) In this regard, the second trajectory T2 can be calculated through the following process. That is, first, calculate what speed and angle the golf ball, which has an initial velocity (V0) and an initial angle (θ0) and moves along a predetermined trajectory (S0), has when it reaches the area (A) near the hole cup (for convenience, (referred to as intermediate velocity (V1) and intermediate angle (θ1)). Next, the golf ball with the intermediate speed (V1) and the intermediate angle (θ1) reaches the area (A) near the hole cup and passes here, and the intermediate speed (V1) and the intermediate angle (θ1) reach the area (A) around the hole cup. Assuming that it is deformed according to its characteristics, calculate the deformation rate (V2) and intermediate angle (θ2) after deformation. Finally, the trajectory (S2) of the golf ball after the area (A) near the hole cup is calculated based on the deformation speed (V2) and the intermediate angle (θ2) (this process calculates the initial velocity (V0) and initial angle (θ0). Based on this, the process may be similar to calculating the first trajectory (T1)). In calculating the second trajectory (T2), the topographical characteristics of the area (A) near the hole cup can be reflected when calculating the deformation rate (V2) and deformation angle (θ2) from the intermediate velocity (V1) and the intermediate angle (θ1). there is.

When the characteristic of the area around the hole cup is the direction in which the grass lies, comparing the case where the grass lies in the forward direction with respect to the direction in which the golf ball rolls and the case in which the grass lies in the reverse direction with respect to the direction in which the golf ball rolls, the forward direction is In this case, the rolling speed of the golf ball may increase, and in the reverse case, the rolling speed of the golf ball may decrease. Taking this into account, if the grass is in the forward direction, the deformation rate (V2) can be set larger than the intermediate speed (V1), and if the grass is in the reverse direction, the deformation rate (V2) can be set smaller than the intermediate velocity (V1). . When the characteristic of the area around the hole cup is the amount of moisture contained in the grass, the higher the moisture content, the slower the golf ball rolls due to the resistance caused by water droplets. Taking this into account, the deformation speed (V2) can be set to be smaller than the intermediate speed (V1) depending on the amount of moisture in the water droplets on the grass. When the characteristic of the area around the hole cup is the topographical contour of the area around the hole cup, assuming that there is an uneven curve around the hole cup due to the terrain contour, the moving speed or direction of movement of the golf ball may be changed due to the curvature. Taking this into account, the deformation rate (V2)/deformation angle (θ2) can be calculated by changing at least one of the intermediate velocity (V1)/intermediate angle (θ1) depending on the type or degree of the bending.

We have explained the process of reflecting the characteristics of the area around the hole cup (the direction in which the grass lies, the moisture condition of the grass surface, the topographical contour of the area around the hole cup, etc.) in calculating the trajectory of the putted golf ball, but this is just an example. This is only an explanation and other methods not described here may be used.

Figure 7 shows a display example of a screen that provides a putting guide by reflecting the characteristics of the area around the hole cup.

Referring to FIG. 7(a), in the putting step, a putting guide (PG) indicating putting information may be displayed on the screen. The putting guide (PG) plays a role in informing the user which direction is best to putt, considering the topographical characteristics of the green area (slope direction, slope, etc.). On a real golf course, users can visually determine the topographical characteristics of the green area and determine their own putting direction. However, in screen golf, the green area is displayed as a two-dimensional image on the screen, so it is difficult to visually determine the topographical characteristics of the green area. do. For example, if the green area shown in Figure 7(a) is slanted in a way that the left side is high and the right side is low, even if the user putsts straight toward the hole cup, the virtual golf ball curves to the right along the slope and There is a high possibility that you will not hole in the hole cup. Therefore, if the green area is sloping in a way that the left side is high and the right side is low, taking into account that the golf ball may curve to the right along the slope, when putting, rather than putting straight toward the hole cup, putt in a direction slightly to the left of the hole cup. It is desirable to putt in a direction, and in FIG. 7(a), the putting guide PG guides the putting direction in a direction biased to the left with respect to the hole cup, taking into account the slope of the green area described above. The putting guide (PG) can be displayed as an arrow, and the putting direction can be indicated by the direction of the arrow, and the putting strength can be indicated by the length or thickness of the arrow.

Referring to FIG. 7(b), in the virtual golf device according to an embodiment of the present invention, the direction in which the putting guide guides may vary depending on whether the user plays in the first mode or the second mode. If a first putting guide (PG1) is provided as a putting guide indicating the optimal putting direction when playing in the first mode, a second putting guide (PG1) different from the first putting guide (PG1) is provided when playing in the second mode. PG2) may be provided. For example, when the topographical characteristics of the area near the hole cup are not considered, when putting in the direction of the first putting guide (PG1), the virtual golf ball moves along the first trajectory (T1) and succeeds in making a hole, and the area near the hole cup When considering the terrain characteristics, it is assumed that when putting in the direction of the first putting guide (PG1), the virtual golf ball moves along the first trajectory (T1) and then a trajectory change (ΔT1) occurs around the hole cup, resulting in a hole-in failure. do. In addition, if the terrain characteristics of the area near the hole cup are not considered, when putting in the direction of the second putting guide (PG2), the virtual golf ball moves along the second trajectory (T2) and fails to make a hole-in, and the terrain characteristics of the area near the hole cup When considering, it is assumed that when putting in the direction of the second putting guide (PG2), the virtual golf ball moves along the second trajectory (T2) and then a trajectory change (ΔT2) occurs around the hole cup, resulting in a successful hole-in. In this case, when the terrain characteristics of the area near the hole cup are not considered, the first putting guide (PG1) is provided as a putting guide, and when the terrain characteristics of the area near the hole cup are considered, the second putting guide (PG2) is provided as a putting guide. It is provided as a guide. That is, the virtual golf device according to an embodiment of the present invention can generate an optimal putting guide according to whether the topographical characteristics of the area near the hole cup are reflected and provide it to the user.
