And the matte image processing unit 314 may provide a matte image so that the matte image can be projected on the whole, or at least a portion of the mat (50). In addition, when the mat image processing unit 314 provides a mat image on the mat 50, including the mat 50, the mat image can be provided so that the mat image can be projected on the outer area of the mat 50. have.

For example, when the mat 50 is divided into a fairway area 51, a rough area 52, and a bunker area 53, each area is divided, and a mat image corresponding to at least one area among a plurality of areas is displayed. can provide Therefore, when the user U puts the golf ball G in the rough area 52 , the mat image processing unit 314 may provide a mat image of a state in which grass has grown lushly. In relation to this, the location where the user U puts the golf ball G may be acquired by the information processing unit 313 through the sensing device 20 or the virtual golf simulation device 320 .

In relation to FIG. 4 , the mat image processing unit 314 may provide a matte image to the bunker area 53 that is one of the plurality of areas. That is, referring to FIG. 4 , it is possible to provide a mat image indicating that the golf ball has been hit in the bunker area 53 . In addition, as shown in FIG. 4 , the mat image processing unit 314 may provide a mat image showing the appearance 410 of sand splatter on the rough area 52 according to the hitting of the golf ball, and is included in the mat image. The sand splatter 410 may be displayed so as to deviate from the mat around the mat 50 .

Also, for example, the mat image processing unit 314 is a course image obtained by imaging the state of the golf course according to the environment in the virtual golf course, for example, weather, temperature, and humidity, regardless of whether the user U swings or not. You can provide a matte image that includes Therefore, for example, when a golf game is played in the rain through a screen image, the mat image processing unit 314 may provide an image of the mat splashing or pooling water on the floor.

That is, according to an embodiment, the mat image processing unit 314 may provide a mat image corresponding to a screen image of a golf course on a virtual golf course.

According to another embodiment, the mat image processing unit 314 may provide a mat image corresponding to the screen image of the virtual golf course before the user U swings.

For example, the mat image processing unit 314 may provide a mat image including information indicating the user's swing turn, and provides a mat image including information for identifying the user (U) who has turned to swing. can do it Accordingly, the user U can know that his/her turn has arrived when his/her ID is displayed through the mat image.

As another example, the mat image processing unit 314 may provide a mat image including a lie so that the user U can refer to it when putting.

As another example, the mat image processing unit 314 may provide a mat image including a putting guide that can guide the putting direction when the user U puts.

At this time, the mat image processing unit 314 may provide a putting guide indicating the direction in which the putting will be made with the starting point at the position where the golf ball is placed, for example, providing a putting guide with the starting point at the point where the tee is located, or The position of the golf ball on the mat may be obtained from the sensing device 20 or the virtual golf simulation device 320 to provide a putting guide using the position of the golf ball as a starting point.

As shown in FIG. 5 in relation to, it is possible to provide a mat image including an arrow 510 indicating a putting guide that suggests a putting direction of the golf ball (G) placed on the mat (50). Accordingly, the user can achieve good putting performance by putting the golf ball in the direction of the putting guide.

That is, the mat image processing unit 314 may provide a mat image including at least one of the user's swing data (information such as pitch, speed, angle, and distance of a golf ball according to the swing) and a course image. Therefore, for example, information such as the speed of a golf ball, a divot, or an image of the sand splashing on the floor or the shaking of the grass may be implemented as a mat image and displayed on the mat 50 .

According to another embodiment, the mat image processing unit 314 may provide a mat image including a virtual interface so that the user U can operate it. Accordingly, as shown in FIG. 6 , a virtual interface 610 may be displayed on the mat 50 . With respect to the interface 610 displayed in this way, the user U may request a manipulation by taking a predetermined motion or positioning a golf club on the interface 610, and the sensing device 20 senses the user's motion, etc. By sensing, the user's manipulation command may be determined based on the user's motion and information displayed through the interface 610, and the virtual golf simulation apparatus may operate according to the command.

In order to provide a sense of reality that the user U presses the button in relation to, an impact sensor or a spring may be embedded in the mat 50 at a location where the virtual interface is provided.

As described above, the mat image processing unit 314 provides a mat image corresponding to a screen image about a virtual golf course, so that the mat image is displayed on the mat 50, and accordingly the mat image is located on the mat 50 It is possible to make the user U feel that he is located on a more realistic golf course.

Meanwhile, the calibration unit 315 according to an embodiment described in this specification may perform calibration to provide a matte image. To this end, the calibrator 315 may perform calibration on the mat image based on at least one of an area and a shape of the mat.

That is, when the mat image is projected onto the mat 50 through the projector 40 as the image processing unit 314 provides the mat image, the projected mat image must be accurately overlapped on the mat 50 to be more realistic. Mats can be provided. In relation to this, for convenience of explanation, the state in which the mat image overlaps in conformity with the mat is referred to as a state in which the mat image is fitted to the mat. Accordingly, the state in which the mat image is fitted to the mat may mean, for example, a state in which each vertex of the mat image and the mat coincides, or a state in which the mat image and each side of the mat coincide.

To this end, the calibration unit 315 may provide a matte image including one or more image reference lines so that the projector 40 can be preferably installed.

In relation to FIG. 7 is a view for explaining the mat image providing apparatus 310 described in the present specification, and shows a state when looking at the projector 40 and the mat 50 from the ceiling of the screen golf system.

Referring to FIG. 7 , the calibration unit 315 transmits a mat image including at least one of a first image reference line 710 , a second image reference line 720 , and a third image reference line 730 through the projector 40 . can be projected At this time, the first image reference line 710 is a line extending from the lens central axis 700 of the projector 40, and when the projector 40 is installed, the first image reference line 710 crosses the middle of the mat. It may be installed to match the mat reference line (711). In addition, the second image reference line 720 may be installed to coincide with the second mat reference line 721 when the projector 40 is installed, and as shown in FIG. 7 , the second mat reference line 721 is a plurality of areas. It may be a boundary of each area on the mat 50 including it, but is not limited thereto and may be a line crossing any point on the mat 50 . In addition, the third image reference line 730 may be installed to coincide with the third mat reference line 731 when the projector 40 is installed, and as shown in FIG. 7 , the third mat reference line 731 is the mat 50 may be the outer boundary of

In this way, by providing the image reference line, the projector 40 can be guided to be preferably installed in the screen golf system 100, but the inexperience of the installer when the projector 40 is installed, problems in the side wall of the screen golf system, etc. Therefore, the projector 40 may not be installed correctly.

8 to 13 are diagrams for explaining that the apparatus for providing a matte image described in the present specification performs calibration.

In relation to the 'projection angle', as the mat image is projected on the floor of the screen golf system through the projector 40, the line connecting from the lens of the projector 40 to the top point of the mat image projected on the floor is the screen It refers to the angle formed with the side wall of the golf system. In addition, the 'recommended angle' means an angle at which the projector is recommended to be installed, and preferably, the line connecting the lens of the projector 40 to the topmost point of the mat may be an angle formed with the side wall of the screen golf system. .

As shown in FIG. 8 , in order for the mat image providing device 310 to operate, the projector 40 must be installed at the position 800 of the side wall of the screen golf system 100, but since it is manually installed, another position can be installed on For example, it may be installed in a higher position 810 or a lower position 820 than the original installation position 800 . In this process, the projection angle may be installed to be different from the recommended angle.

Accordingly, even when the projector 40 is disposed based on the image reference line and the mat reference line, the mat image 900 may not be projected with the mat 50 as shown in FIG. 9 . That is, through the projector 40, the first image reference line 710, the second image reference line 720, and the third image reference line 730 are respectively the first mat reference line 711, the second mat reference line 721 and the second image reference line 721. When the mat image 900 is projected to match each of the three mat reference lines 731 , the projector 40 is positioned higher than the original position, so that only a portion of the mat 50 can be projected. On the other hand, if the projector 40 is positioned lower than the original position, the mat image 1000 does not match the mat 50 as shown in FIG. 10 , and in particular, the mat image 1000 is the area of the mat 50 It can be projected out of range.

The image reference line may be used for installation of the projector 40 or may be used to confirm whether the projector 40 is installed at a recommended position. Therefore, when the calibrator 315 projects the matte image including the image reference line, at least one of the image reference lines does not match the matte reference line, or the matte image is fitted with the mat despite all of the image reference lines coincide with the matte reference line If not, it may be determined that calibration should be performed. Additionally, the calibrator 315 may determine that calibration should be performed when determining that the swing plate exists.

11 is a view for explaining that the projection angle of the mat image is different from the recommended angle when the projector 40 is installed on the side wall of the screen golf system lower than the recommended installation position.

The mat image in FIG. 11 is projected wider than the mat 50 as shown in FIG. 10 . Accordingly, as shown in FIG. 10 , an error distance x, which is a distance from the topmost point of the mat to the topmost point of the mat image, may be measured.

That is, referring to FIG. 11 , in a state in which the projector 40 is installed lower than the recommended installation position, the mat image may be projected from the point 1110 to the point 1130 , which means that the mat 50 is the point 1120 . ) to the point 1130, it is projected out of the mat area. Accordingly, the mat image can be projected on the mat at a projection angle (C), which is projected at an angle different from the recommended angle (A) when installing the projector. Accordingly, when the mat image is projected on the mat, the mat image must be corrected, and the calibration unit 315 may calculate an error angle B for correction.

That is, the calibrator 315 may calculate the error angle B according to Equation 1 below.

Formula 1:

At this time, the height (H) from the ground to the projector 40, the mat distance (D), which is the distance to the topmost point 1120 of the mat based on the wall where the projector 40 is installed, and the mat image from the topmost point 1120 of the mat The error distance (x), which is the distance to the uppermost point 1110 of the , and the recommended angle (A) are values that can be obtained by projecting the mat image after the projector 40 is installed.

On the other hand, since the turn at bat installed in the screen golf system 100 can be moved while the angle is changed by the swing plate, it is necessary to adjust the zoom magnification.

According to an embodiment, the manager of the screen golf system 100 may determine a zoom magnification value for projecting the mat image while adjusting the zoom magnification of the projector 40 .

According to another embodiment, the calibrator 315 may calculate a zoom magnification value of the matte image.

That is, although the mat image can be corrected by calculating the error angle B, the mat image may be displayed smaller than the mat or larger than the mat as the swing plate angle is changed.

Therefore, it is necessary to correct it by adjusting the zoom magnification value of the matte image. To this end, the calibrator 315 may additionally extract a zoom magnification value by allowing the virtual golf simulation apparatus 320 to adjust the swing plate.

To this end, the calibrator 315 may calibrate the mat image by calculating a zoom magnification value based on at least one of a side and an area of the mat. Also, the calibrator 315 may determine a zoom magnification value based on at least one of sides and areas of the mat image and the mat, and reduce or enlarge the mat image based on vertices of each of the mat image and the mat.

In this case, the calibrator 315 may reduce the matte image 1200 based on the

vertices

1210 , 1211 , 1220 , and 1221 of the mat image 1200 and the mat 50 , respectively.

That is, the image processing unit 314 may provide the matte image by correcting it based on at least one of the zoom magnification value and the error angle when providing the matte image as the zoom magnification value and the error angle are obtained. For example, the image processing unit 314 may acquire the projection angle based on the error angle and the recommended angle, and may correct the matte image according to a correction equation corresponding to the projection angle. In addition, the image processing unit 314 may reduce or enlarge the matte image according to the zoom magnification value, but correct the matte image so that the vertices of the matte image correspond to the vertices of the matte.
