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 an example of a process for forming a play image in the virtual golf device of FIG. 1, and FIGS. 3 to 9 is a diagram specifically showing each step of the play image formation process.

Referring to Figure 1, the virtual golf device according to an embodiment of the present invention includes a hitting plate 10, a control unit 20, a detection unit 30, a photographing unit 40, an input unit 50, and a sound unit 60. and a display unit 70.

The hitting plate 10 is an area where the user is positioned to hit the golf ball. The hitting plate 10 may be a plate-shaped object that is provided separately, or it may not be a separate object but simply a part of the floor where the virtual golf device is installed and where the user is located. Although not shown in the drawing, an auto tee with a structure that can move up and down is installed on the hitting plate 10, and a golf ball for hitting can be automatically provided to the user through the auto tee.

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. In addition, although not shown in the drawing, the control unit is provided with an image forming means, and when the user selects a specific golf course to play, an image of the golf course is formed through the image forming means, and this image is displayed on the display unit ( 70) and can be displayed.

The control unit 20 includes a calculation unit 21, a storage unit 22, a determination unit 23, an image processing unit 24, and an editing unit 25. The calculation unit 21 performs a process of calculating what kind of trajectory the golf ball hit by the user will take under the assumption that it was hit on an actual golf course. The storage unit 22 includes a storage device such as memory or a hard disk, and stores various data necessary for the operation of the control unit 20. The determination unit 23, the image processing unit 24, and the editing unit 25 play the role of forming and editing play images related to the user's play, details of which will be described later.

The detection unit 30 is used to detect the movement of the golf club or the movement of the golf ball hit by the user to determine the physical state information about the hit golf ball, and is a camera that can capture the movement of the golf club or golf ball. Detection means such as a sensor or sensor 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, information on the state of a golf club or a golf ball hit by a user can be determined. The cameras, detection sensors, etc. may be used alone or together, and only one or multiple units may be used. The information obtained through the detection unit 30 is transmitted to the control unit 20 and used in the calculation process. The photographing unit 40 functions to capture the motion of the user actually hitting a golf ball. If the image of the user's striking motion is called a 'user image', the recording unit 40 plays a role in generating the user image. The sensing unit 30 and the photographing unit 40 do not necessarily have to be provided separately, and one sensing means can be configured to simultaneously perform the roles of the sensing unit 30 and the photographing unit 40. For example, if a camera is used as a sensing means, the camera can detect the movement of a golf club or golf ball (role of the sensing unit 30) and also film the user's swing motion (role of the filming unit 40). .

The input unit 50 is used to receive various types of information from the user, and a keyboard or mouse can be used. A login process that requires the user to log in before providing the service may be applied to screen golf. When the login process is applied, the user must enter his or her ID or password, and the input unit 50 may be used at this time. Additionally, the input unit 50 can be used in screen golf when the user selects a play option such as the golf course he or she wants to play or the difficulty level of play.

The sound unit 60 may include an audio device such as a speaker, and serves to guide the user on the progress of the game and play various sound effects according to the progress of the game.

The display unit 70 includes display devices such as a projector and screen. The projector projects golf-related images on the screen so that the golf course and golf balls are displayed on the screen, and the screen displays the projected images to show to the user. In this specification, some objects displayed on the screen may be expressed with the term 'virtual', which is used to mean that they are displayed as images on the screen, and to avoid confusion with objects that exist in the real world. will be. For example, 'virtual golf ball' refers to a golf ball displayed on a screen, and is expressed by adding the term 'virtual' to avoid confusion with the actual golf ball that a user hits in the real world.

A virtual golf device is a device that is installed at a screen golf course for home or public use to allow screen golf to be played. When a user plays screen golf, the virtual golf device operates as follows. When a user hits a golf ball, the sensing unit 30 detects the physical state, such as the movement of the golf club or the moving speed or direction of the golf ball hit by the user. The information detected by the sensing unit 30 is transmitted to the control unit 20, and the calculation unit 21 in the control unit 20 performs a calculation process of calculating the expected trajectory of the golf ball based on the transmitted information. . The display unit 70 displays an image of a virtual golf ball moving according to the expected trajectory calculated in the calculation process. At this time, the virtual golf ball flies along the calculated trajectory and lands at a specific point on the virtual golf course on the screen. , the user continues the next hit from the point where the virtual golf ball lands. The above operation process is repeated in the user's next hit.

In the screen golf play process described above, the determination unit 23, the image processing unit 24, and the editing unit 25 participate in the operation of forming the user's play shape. Here, the play video refers to a video created by combining a user video and a display video (video displayed on a display means such as a screen is called 'display video' for convenience). Hereinafter, the process of forming a play video will be described with reference to the drawings.

Referring to FIG. 2, the process of forming a play image includes first to eighth steps (S1, S2, S3, S4, S5, S6, S7, and S8). Here, in order to distinguish each stage, they are named stages 1, 2,...,8 for convenience. However, these stages do not necessarily have to proceed in the order of stages 1, 2,...,8, and some stages may be Additional steps may be omitted or added, and the order of progress may also be changed.

In the first step (S1), a user image is formed. The user video is a video of the user's hitting motion, and as shown in Figure 3, it mainly shows the user's swing posture (including the swing posture before and immediately after hitting the golf ball). It contains. Although not shown in FIG. 3, the user image may include an image of a golf ball for hitting (including images of a golf ball in a stationary state before hitting and an image of a golf ball moving after hitting, etc.).

In the second step (S2), it is determined whether to save the user image. This determination may be performed by the determination unit 23 of the control unit 20. That is, the determination unit 23 determines whether the user image is worth saving, and whether the user image is worth saving can be determined from various perspectives.

For example, it may be determined whether to store the user's image based on the result of the user hitting a golf ball. Referring to FIG. 4, when a user hits a golf ball, the calculation unit 21 calculates which trajectory the hit golf ball will move and at which point it will land based on the sensing information from the detection unit 30. In calculating this expected trajectory, various methods can be applied, one of which is to detect parameters representing the physical state of the golf ball after hitting and calculate the trajectory from this. The parameters may include the speed of the golf ball (V), the azimuth angle (ϕ) indicating the direction on the horizontal plane of the golf ball flying by hitting, and the vertical angle (θ) indicating the angle at which the golf ball is inclined with respect to the horizontal plane. The trajectory of a golf ball can be calculated by applying a calculation model using physical laws based on parameters such as speed (V), azimuth (ϕ), and elevation angle (θ). By calculating the trajectory like this, you can determine whether the hit is worth saving. For example, if the user's hit is a long shot with a very long distance, or if the user's hit causes the golf ball to land exactly near the hole cup, etc., if a hit that can be recognized as a good shot is made, the user will be responsible for the hit. You can decide to save the video. Or, conversely, even if the user's hit is a bad shot, the user's video can be considered worth saving. For example, if a hook or slice occurs that causes the golf ball to deviate significantly from the correct hitting direction, the user may want to analyze his/her hitting posture to reduce the occurrence of hooks or slices in the future, and for this purpose, there is a device that can save the user's swing video. You can decide it's worth it. In this way, the determination unit 23 determines whether to store the user video based on a good shot, a bad shot, or various other criteria. The determination unit 23 does not necessarily have to be provided separately, and the calculation unit 21 may perform the role of the determination unit 23. That is, when the calculation unit 21 calculates the user's hitting result, the calculation unit 21 can determine whether the user's image is worth saving based on the calculated hitting result.

Referring to FIG. 5, when the calculation unit 21 calculates the movement of the golf ball, an image of a virtual golf ball corresponding to the actual golf ball hit by the user is displayed on the screen, moving according to the results calculated by the calculation unit 21. The virtual golf ball moves as calculated and lands at a specific location on the virtual golf course, and the user continues the next hit from the landing location. An image displayed on a screen, etc., as shown in FIG. 5, is referred to as a 'display image' in this specification. Here, when the virtual golf ball is shown moving, if the virtual golf ball is small and cannot be easily identified by the user, the virtual golf ball itself may not be displayed on the display image and only the trajectory may be displayed.

Referring again to FIG. 2, if the decision unit 23 determines whether to save the user image and decides not to save it, the user image captured in the third step (S3) is deleted. Additionally, if the decision unit 23 determines whether to save the user image and decides to save it, the fourth and fifth steps (S4 and S5) are executed. In the fourth step (S4), a display image is obtained. The display image can be obtained by recording the image displayed on the screen. Alternatively, if the display image is formed in a specific file format before being displayed on the screen, the display image can be obtained by obtaining the file.

In the fifth step (S5), the video processing unit 24 generates and stores a play video. The play image can be formed by matching and combining the display image with the user image. The image processing unit 24 may be involved in the process of acquiring the display image. In this case, the image processing unit 24 may form a play image by combining the acquired display image with the user image received from the photographing unit 40. . Here, matching a display image to a user image does not mean randomly combining a random user image with a random display image, but rather a display image showing the result of the hit to the user image that captures the motion of the user hitting a golf ball. It means combining. For example, as shown in FIG. 6, a play image can be formed by continuously attaching a display image that appears as a result of a hit in the user image to the user image. Through the play video, the user can see the swing motion of hitting the golf ball, and following the swing motion, the play result (display video) of the swing can be viewed. The fifth step (S5) is not essential and can be omitted. If the fifth step (S5) is omitted, the play video is not formed. In this case, the operation performed on the play video in the subsequent steps (steps 6-8 (S6, S7, S8)) involves the user video and /Or it can be done by targeting a display image.

Steps 1, 2, 4, and 5 (S1, S2, S4, and S5) represent the process of forming a play image when the user hits a golf ball once. After the user completes one hit and a play video for that hit is formed, when the user makes the next hit, the next hit goes through steps 1, 2, 4, and 5 (S1, S2, S4, S5) and then another hit. A play video may be formed. The golf course on which the user plays screen golf usually consists of 18 virtual golf courses (18 holes), and the user plays on all or some of the 18 courses. When playing 18 holes, the user usually plays golf. During the game, dozens or more than 100 hits can be made, and a play video can be created each time the user hits. For example, assuming that the user made a total of 80 hits in 18 hole play, and decided to save the video for 20 of the 80 hits and not to save the video for the remaining 60 hits, A total of 20 play videos can be formed by combining 20 user videos with a display video showing the result of hitting when a hit is made in the user video. As shown in FIG. 7, the plurality of play videos may each be stored in a temporary folder, and the temporary folder may be formed in the storage unit 22 or the like.

Referring again to FIG. 2, the sixth to eighth steps (S6, S7, and S8) proceed after the user's play ends. In the sixth step (S6), the user's intention on how to process the stored play video is confirmed. For example, as shown in FIG. 8, a message asking the user whether he or she wants to save the play video may be displayed on the screen. If the user does not want the saved video, the seventh step (S7) is performed and all of the plurality of play videos stored in the temporary folder, etc. are deleted. If the user wants a play video, the eighth step (S8) proceeds. In the eighth step (S8), a plurality of play videos can be edited into one lightweight video. Here, 'lightweight video' refers to a video whose file size is reduced by deleting some scenes from among the plurality of scenes that make up each play video. The lightweight video can be said to be a type of 'highlight video' that compiles only the scenes that users may be interested in among the play videos. The process of forming a lightweight video may include combining a plurality of play videos to create one video. In other words, the process of forming a lightweight video includes ① bundling multiple play videos into one video and ② deleting some of the scenes in the multiple play videos to create a highlight video. Here, the lightweight image formation process may proceed in the order of ② and ①, and also, in the lightweight image formation process, all operations ①/② do not necessarily have to be executed, and either one may be omitted and only the remaining one may be executed.

One of the reasons for saving the play video is to provide it to the user and show it to the user. If a lightweight video is formed while saving the play video, the file size is reduced, so the operation time can be reduced when provided to the user, and some scenes are also By being deleted, the viewing time of the original video can be prevented from becoming too long, so the user can watch the entire play video without getting bored through the lightweight video.

Referring to FIG. 9, the upper portion of FIG. 9 represents a state of combining multiple play videos into one video, the middle portion represents the process of editing by deleting some scenes from the single video, and the lower portion represents the process of editing. Indicates that the lightweight video has been completed. Here, in the editing process of forming a lightweight video, scenes to be deleted from the play video can be automatically selected by a computer program. For example, as shown in the middle part of FIG. 9, if the user may be more interested in the initial scene containing the moment of the swing motion, such as a tee shot, the scene after the middle may be deleted, In cases where the user may be more interested in a later scene containing the moment a virtual golf ball lands or stops on a virtual golf course, such as a second shot or putting shot, the scene before the middle can be deleted. Artificial intelligence technology may be applied to the computer program used to form lightweight images. Here, artificial intelligence is a program that artificially implements human intellectual ability, and machine learning technology can be applied to artificial intelligence. By applying machine learning technology, artificial intelligence can analyze a large number of input data and derive results on its own, unlike traditional programs that derive results determined by rules. For example, if a plurality of play videos are used as learning input data and a lightweight video made from the plurality of play videos is used as learning output data, and a plurality of learning input data and output data sets are provided to the artificial intelligence to learn, the learning is completed. can be obtained, and if input data (multiple play videos) whose results are unknown are input to the artificial intelligence that has completed learning, output data (a lightweight video created by editing the plurality of play videos) will be derived based on the learned content. You can.

The process of forming a play image in the virtual golf device of FIG. 1 has been described with reference to FIGS. 2 to 9. The process of forming a play image described here is one example of various applicable methods, and is not described here. Other methods may also be applied.
