The present invention is a virtual simulation of a sport called bowling, in which a user combines actual bowling elements and virtual bowling elements embodied in an image to perform bowling with actual bowling balls, and implements a virtual bowling simulation image To experience a result of the bowling through the virtual bowling simulation system.

Bowling is a popular sport and is a sport that many users of various levels can easily enjoy. In general, it requires a considerably large site to build a bowling alley. It also has an automation system for placing bowling pins and bowling pins, 23m of lane, ball transport system for ball collection, etc. It costs a lot of facility expenses, management fee, and site fee. However, because it is mainly located on the outskirts rather than the downtown area due to its wide absence, The profitability is very low and the bowling alley is gradually disappearing.

Therefore, the length of the actual bowling lane is largely reduced, and a screen is installed at the end of the reduced lane, and a simulated image of the bowling, such as a so-called screen golf system, is projected onto the screen, A so-called screen bowling system in which a virtual bowling pin is impacted while a virtual bowling ball is simulated on the screen image based on the direction and speed of the ball is detected by sensing the movement of the bowling ball.

However, in the conventional screen bowling system as described above, since the actual bowling ball rolls toward the screen, the screen must be lifted from the floor by a space in which the bowling ball can pass, so that the lanes on the image of the actual lane and the screen are completely separated In addition, since it is not connected, the user who enjoys the screen bowling causes a considerable sense of heterogeneity, reduces the concentration of the bowling, and the image is projected on the screen. Therefore, the sharpness of the image quality is significantly lowered, .

A virtual bowling simulation image is implemented in an entirely novel way by installing a screen in a conventional screen bowling system and projecting an image, and an image related to a virtual bowling lane and a bowling pin, that is, a virtual bowling image, So that the actual bowling ball can pass through the actual lane to the video so that the user who enjoys the virtual bowling can improve the reality and immersion of the bowling sport And to provide a virtual bowling simulation system.

A virtual bowling simulation system according to an embodiment of the present invention includes: a lane bottom portion forming a lane corresponding to a length less than half of an actual bowling lane; A virtual bowling environment image regarding a virtual lane and a bowling pin for a lane having a remaining length, which is implemented at an end of the lane bottom and is connected to the lane bottom, is implemented as a virtual image so that the lane bottom and the virtual lane on the virtual image can be connected A virtual image implementation device for realizing an image; A continuous image of the actual bowling ball that the user pitches on the lane bottom portion is acquired and analyzed and the position coordinate information on the bowling ball on the lane bottom portion and the sensing data such as the ball speed, Sensing device; And a moving image processing unit for processing image data for image implementation of the virtual image implementing apparatus and simulating a virtual bowling ball on a virtual bowling environment image implemented by the virtual image implementing apparatus based on the sensing data of the sensing apparatus And a controller for causing the controller to be implemented.

The detailed contents of the virtual bowling simulation system according to the present invention will be described with reference to the drawings.

Virtual Bowling Simulation System

The overall configuration of a virtual bowling simulation system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

FIG. 1 is a view showing an actual implementation example of a virtual bowling simulation system according to an embodiment of the present invention. FIG. 2 is an enlarged view of the main configuration of the virtual bowling simulation system shown in FIG. 1, FIG. 4 is a block diagram illustrating a control system of a virtual bowling simulation system according to an embodiment of the present invention. Referring to FIG.

1 to 4, a virtual bowling simulation system according to an embodiment of the present invention includes a lane bottom 100, a virtual image implementation device 200, a sensing device 300, and a control device 500 .

The lane bottom portion 100 forms a gutter GT with the lane portion 101 where the actual bowling ball rolls, and forms a lane corresponding to a length equal to or shorter than half the standard lane of the actual bowling.

The virtual image-realizing device 200 is a completely new replacement for projecting an image on a conventional screen. The virtual image-realizing device 200 has a structure in which the remaining length of the lane, which is implemented at the end of the lane bottom 100 and is connected to the lane bottom 100, A virtual bowling environment image of a virtual lane, a bowling pin, and the like is implemented as a virtual image 230 to implement an image so that a virtual lane on the lane bottom 100 and the virtual image 230 can be connected.

Preferably, the sensing device 300 is configured to acquire and analyze an image at an angle of view that is installed at an upper side and downwardly viewed from above. When the actual bowling ball that the user hits is moved on the lane bottom portion 100 And calculates sensing data such as positional coordinate information on the bowling ball on the lane bottom portion 100 and the ball velocity, direction, and spin information.

The control device 500 processes image data for image implementation of the virtual image implementing device 200 and generates virtual bowling implemented by the virtual image implementing device 200 based on the sensing data of the sensing device 300. [ A virtual bowling ball is simulated on an environmental image so that a moving image is implemented.

3 and 4, when the user P holds the bowling ball in the ball rack BR provided in the approach area and pivots the bowling ball toward the hallucination device 200 from the lane bottom, As the bowling ball moves on the lane bottom part 100, the sensing device senses the movement of the ball, calculates sensing data, and transmits the sensed data to the control device. When the bowling ball passes inside the hall device, The bowling ball behind the virtual image disappears). In the imaginary lane on the image of the virtual image, the virtual bowling ball is simulated based on the sensing data and the moving image is realized.

A ball collecting / equipment room is provided at the rear of the virtual image forming apparatus 200, and a ball collecting apparatus 700 and a control apparatus 500 are provided.

The control unit 500 includes a control unit 510, a data storage unit 520 and an image processing unit 530. The data storage unit 520 stores image data, audio data, And system data, and the image processing unit 530 is a unit for processing image data for realizing a virtual image.

Various operations for simulation using sensing data transmitted from a sensing device and control of an image processing unit can be performed by the control unit 510. [

2, the virtual image implementing apparatus 200 includes a half mirror 220 disposed inside the glass panel 205 to allow a bowling ball to pass therethrough by forming a space under the glass panel 205, The image of the image output panel is reflected to realize the virtual image 230. Since the virtual image 230 is implemented, there is no possibility of physical collision with the bowling ball.

Since the virtual image realizing device 200 realizes a virtual image to be connected to the lane bottom 100, the space above the virtual image realizing device 200 can be utilized, and the display device 600 can be installed on the front surface as shown in FIG. 1 and FIG. have.

Not only the information such as the score can be provided through the display device 600, but also information about the current situation, information about the trajectory of the bowling ball after the user hits the bowling ball, information about the recording, It is possible to output image information and the like related to cheering the bowling play of the user, and in particular, to output the advertisement information.

In other words, conventionally, the advertisement image has to be outputted passively so as not to overlap with the main image on the screen. In the present invention, since the virtual image portion and the display device portion are completely separated and do not affect the implementation of the virtual image, Free advertising information can be output.

In addition, a wireless control terminal 800 is provided on the approach area where the user is located and is provided to wirelessly communicate with the control device 500, so that the user can receive information such as the current score through the control terminal 800, And various settings such as setting and change of the setting value can be operated.

Virtual image implementation device

The configuration of the virtual image realizing device 200 will be described in more detail with reference to FIG. 2 and FIGS. 5 to 8. FIG.

FIG. 5 is a schematic view of a virtual bowling simulation system according to an embodiment of the present invention, which is a simplified view of the configuration of a virtual image forming apparatus. FIG. 6 is a virtual image of a virtual bowling simulation system according to an embodiment of the present invention. FIG. 7 is a view for explaining a system driving situation when a user throws a bowling ball in the system shown in FIG. 5, and FIG. 8 is a diagram for explaining the implementation of a virtual image Fig.

The virtual image realizing device 200 includes a frame 202 provided inside a housing 201 of a predetermined size and fixed by the frame 202. An image output panel A half mirror 220 provided below the image output panel 210 reflects an image of the image output panel 210 and reflects the image of the image output panel 210 to the dark room 210 of the housing 201, And may be configured to embody a virtual image 230 inside.

The image output panel 210 may be fixed at a predetermined angle in the direction toward the lower half mirror 220 under the upper end 203 of the frame 202. At the rear end of the frame 202, A mounting portion 502 can be provided on which the mounting portion 500 can be installed.

The half mirror 220 has a reflectance and a transmittance for light, and transmits a part of the light of the image output panel 210 and partially reflects the light, Thereby forming a kind of holographic image.

7, the virtual image 230 is formed on the rear side by the image output panel 210 and the half mirror 220, and the virtual image 230 is in contact with the lane bottom 100, The virtual lane on the image of the actual lane bottom 100 and the virtual image 230 can be made to look like one lane (of course, the actual lane and the lane on the image are, It is possible to realize a much more realistic image compared to a case where the image is implemented with a screen or the like at least in the past although it is seen to be separated by the naked eye.

Therefore, when the user P pierces the bowling ball B, the bowling ball B should be spaced below the glass panel 205 (the height d of the space is greater than the diameter of the bowling ball B) The image (i.e., the virtual image 230) viewed from the position of the user P while passing through the virtual image 230 without any physical contact while passing through the lane bottom portion 100) and can be seen as natural.

8 shows the angle adjustment of the half mirror 220, which can make the virtual image 230 most visible.

In the case of the half mirror 220a having a gentle angle in FIG. 8, since the viewing angle AVa of the user P is narrow, a portion NV between the virtual image 230 and the bottom is not visible .

On the other hand, in the case of the half mirror 220b having a sharp angle, since the viewing angle AVb seen from the user P is wide, a section DN in which a part of the virtual image 230 is not visible by the bottom may occur .

Therefore, it is preferable that the half mirror is fixed at an appropriate angle so that the length of the DN portion can be minimized while preventing the NV portion from occurring.

Of the sensing device Sensing method  And virtual bowling video implementation method

9 and 10, a sensing method of a sensing device of a virtual bowling simulation system according to an embodiment of the present invention and a method of implementing a virtual bowling image using the sensing method will be described.

FIG. 9 is a diagram for explaining a sensing device of a virtual bowling simulation system according to an embodiment of the present invention for sensing a bowling ball and calculating sensing data therefrom, and FIG. A sensing method of a sensing device of a bowling simulation system, and a process of implementing a virtual bowling image of a control device.

As shown in FIG. 9, the sensing device can sense a part or the entire area of the lane bottom 100 with the angle of view (FOV).

The sensing device analyzes the extracted ball sensing area DR by extracting a ball sensing area DR having a predetermined size for each frame while acquiring an image of the angle of view FOV, Trigger regions (TR) having a predetermined size as a connected region or an adjacent region are also extracted and analyzed.

10, the sensing device acquires an image in the angle of view, extracts a ball-sensing area DR therefrom, and starts analyzing (S100). Then, in the extracted ball-sensing area DR, It is detected whether there is movement of the object (S110).

The motion of the object is determined by setting a difference image of an image of two adjacent frames or consecutive frames or a background image of a state without a bowling ball as a reference image and calculating a difference It can be detected through video.

If motion of an object is sensed in the ball detection area DR, it is determined whether the sensed object is a bowling ball (S120).

At this time, whether or not the bowling ball is detected can be detected by analyzing the degree of roundness of the object (the bowling ball is a rigid body, so that the shape is always uniformly rounded), the aspect ratio, and the size.

When it is determined that the moving object in the ball detection area DR is a bowling ball, the position of the detected bowling ball, that is, the position coordinate information of the center point, can be detected.

Bowling balls are large and heavy, so they do not break even if there is a spin in a short section. Therefore, as shown in FIG. 9, the position B1 of the bowling ball at the first appearance of the ball in the ball sensing area DR and the coordinates of the ball center point of the ball B2 at the end of the ball sensing area DR Respectively.

Of course, the position coordinates of the ball at an arbitrary point in the ball detection area DR and the coordinates of the ball at an arbitrary point of time other than the point coordinates of the ball may be calculated, respectively. Hereinafter, the position of B1 is referred to as a first ball position, and the position of B2 is referred to as a second ball position.

In this way, the sensing device performs position coordinate sensing and storage of the ball (S130).

Then, the sensing device extracts and analyzes the trigger area TR to determine whether the bowling ball has entered the trigger area TR (S140).

If the bowling ball has entered the trigger area TR (if the bowling ball Bt is detected as a result of the extraction and analysis of the trigger area TR), the sensing device may detect the bowling ball Bt as a trigger, The ball velocity and direction are calculated using the ball center point coordinates of the position and the ball center point coordinates of the second ball position, and the spin of the ball is calculated (S150).

The velocity of the ball using the first ball position B1 and the second ball position B2 can be calculated using the distance between the two center points and the time difference, 2 The direction of the ball can be obtained using the angle information of the line connecting the center point of the ball position B2.

On the other hand, a spin calculation method of the bowling ball will be described. The method of calculating the spin of the bowling ball is, for example, a method of using the trajectory of the bowling ball and a method of calculating the characteristic of the surface of the bowling ball (arbitrarily given marker, indication of the brand of the ball, ) Can be used.

First, a method of using features of the surface of a bowling ball will be described. A bowling ball is extracted from an image of a continuously obtained bowling ball (e.g., an image of the ball sensing area extracted from the acquired image) (A marker, a brand of a ball, a display of a logo, and a shape or a foreign substance attached to the surface of a bowling ball) by using image edge information or the like from the ball to generate a feature map. A feature map generated from a first ball (a bowling ball extracted from a first image) of the first image is divided into a first feature map, a second ball of a second image that is a contiguous or a few frames skipped adjacent image A bowling ball extracted from the bowling ball) is referred to as a second feature map.

While rotating the generated first feature map in various directions (a first feature map rotated at an arbitrary rotation axis and a rotation angle is referred to as an arbitrary rotation feature map ), The arbitrary rotation feature map is compared with the second feature map, and the rotation axis and the rotation angle when the correlation between the arbitrary rotation feature map and the second feature map are the highest are found and the spin of the bowling ball is calculated .

On the other hand, a method of using the trajectory of the bowling ball will be described. This is a method of estimating the amount of rotation using the trajectory of the bowling ball.

Here, the Index of Rotation is used as a reference value that affects the rotational motion of the ball, and the velocity index of the various bowling balls and the curve level (curve level) The value of the rotation index is calculated by using the calculated value as the value of each speed value and the inclination degree, and the defined value is made into a table (this is called a 'rotation table').

That is, when the values of the velocity value of the bowling ball and the bowing degree of the bowling ball are respectively calculated, the value of the rotation index defined for the corresponding value can be obtained through the rotation table.

The spin of the ball can be calculated by determining the value of the rotation index obtained as described above as the estimated value for the side spin of the bowling ball.

When the sensing device calculates the velocity, the direction and the spin of the ball as described above (S170), the sensing device calculates the coordinates of the position where the bowling ball is finally detected before disappearing in the angle of view, i.e., The coordinates of the last position are detected and transmitted to the controller (S170).

Hereinafter, the present invention relates to a method for implementing a simulation image of a virtual bowling ball on an image (virtual image) using sensing data transmitted from a sensing device as described above.

The controller processes the images related to the virtual lanes (including all of the images including the virtual bowling pins) from the start of the virtual bowling play using the image data stored in the data storage unit (S200) And outputs the image through a video output panel (S210).

When an image is output through the image output panel, the virtual image of the virtual lane or the like is implemented through the half mirror as described above, so that the actual lane bottom and the virtual lane are connected to realize a natural image .

The control device receives the sensing data from the sensing device, places a virtual bowling ball at the same coordinate position as the last position coordinate in software, and controls the physical engine based on the sensing data (e.g., velocity, direction and spin of the ball) The simulation of the virtual bowling ball is performed (S220).

Simulation of the virtual bowling ball is not implemented on the image for a predetermined time but the virtual bowling ball is simulated on the image (virtual image) while the predetermined time passes (the bowling ball continues to move) The image is implemented and displayed to the user.

Referring to FIG. 9, assuming that the last position of the bowling ball detected by the sensing device is Bf, the control device displays the virtual bowling ball Bv1 at the same coordinates as the last position coordinate received from the sensing device And the simulation proceeds based on the velocity, direction, and spin of the ball delivered from the sensing device.

In this case, the simulated virtual bowling ball proceeds from Bv1 to Bv2 -> Bv3 -> Bv4. In this interval, the actual bowling ball has not yet disappeared from the user's field of view (the actual bowling ball disappears behind the virtual image That is, a state in which the actual bowling ball is visible to the user, but not visible to the sensing device), so that the actual bowling ball is moved and the simulation by the simulation of the virtual bowling ball as described above is performed simultaneously with Bv1 to Bv4 State.

The actual bowling ball disappears to the back of the virtual image over time. At this time, a simulated image in which a virtual bowling ball appears on the virtual image naturally as the actual bowling ball disappears can be implemented.

Here, the simulation image of the movement of the virtual bowling ball can be formed by fusion of the ball's linear motion and the ball's rotational motion, and is realized by the physics engine. The linear motion of the ball by the physical engine is implemented by applying data necessary for linear motion of the rigid body, such as data on the speed and direction of the ball calculated by the sensing device, as well as the mass of the ball and the friction coefficient of the lane , The rotational motion of the ball by the physical engine can be implemented by applying data necessary for rigid rotational motion, such as data on the spin of the ball.

The coefficient of friction of the lane can be set in advance, and the setting may be changed by the user's operation, or may be changed also by the setting of the oil zone or the like.

The mass of a bowling ball is a value that can be determined by inputting or setting information about a bowling ball that the user wants to use at the beginning of the bowling play.

Therefore, as described above, the two elements of the linear motion of the ball and the rotational motion of the ball are fused, so that simulation of the movement of the virtual bowling ball can be performed.

Referring back to FIG. 10, as described above, when the virtual bowling ball is simulated by the sensing data and the physics engine, the image (virtual image) is formed in the portion where the actual bowling ball arrives A simulated image in which a virtual bowling ball moves naturally on an image (virtual image) can be realized while an image of a simulated bowling ball appears before the virtual bowling ball.

A virtual bowling ball collides with virtual bowling pins on the image (virtual image), and these parts are also simulated by the physics engine, so that images of how many virtual bowling pins fall down can be implemented and the score can be calculated accordingly S230).

The process of the sensing device and the control device according to the pitching of the single bowling ball described so far proceeds in the same manner again in the next pitching and progresses until the bowling competition is ended and the score is calculated.

Realization of appearance of actual bowling ball and virtual bowling ball

The user can preset the bowling ball he / she wants to use before proceeding with the virtual bowling game through the system according to the present invention. In this case, when the user matches the bowling ball (virtual bowling ball) which can be selected by the program with the bowling ball actually used in the virtual bowling arena, and the appearance of the virtual bowling ball when each of the bowling balls is implemented on the image When the user sets the same, a virtual bowling ball having the same appearance as that of the corresponding bowling ball is displayed on the image when the user pitches the actual bowling ball, thereby enhancing the sense of realism and immersion.

However, when the user performs a bowling game using his / her own private ball rather than a bowling ball provided in the store, the sensing device or the control device does not have information on the individual ball, If a bowling ball appearing on the image (image) is implemented with a different appearance from the individual bowling ball, the user can feel a sense of heterogeneity.

In the virtual bowling simulation system according to an embodiment of the present invention, in order to enable a user to enjoy virtual bowling play using a personal bowling ball, a separate bowling ball A scanner may be provided.

A separate scanner scans the individual bowling ball and stores information about its appearance, such as size, shape, color, pattern, etc., so that the controller can implement the simulation image using the information of the stored bowling ball can do.

Alternatively, a camera device capable of sensing the appearance (shape, color, pattern, etc.) of the bowling ball at a position adjacent to the sensing device may be provided so that the user simply punches his or her own bowling ball without additional scanning, Detects the individual bowling ball, calculates the appearance information of the bowling ball, and transmits the calculated appearance information to the controller so that the controller can implement the simulation image using the information of the individual bowling ball.

It is also possible to implement the function of the camera device itself without separately providing the camera device.

11, information on the appearance of the bowling ball B moving on the lane bottom 100 is transmitted to the control device so that the bowling ball (B) on the imaginary lane VR on the image (virtual image 230) A virtual bowling ball VB having the same appearance as the game ball B shown in FIG.

Oil zone (or Dry zone Implementation of Virtual Bowling Simulation Image by Setting

The user can set a specific oil zone or set a specific dry zone on the virtual lane VR on the virtual image 230 as shown in Figs. 11 (a) and 11 (b).

Depending on the length of the oil zone, the location and length of the dry zone, etc., the breakpoints of spinning balls can vary and can have a significant impact on the outcome of the game.

It is possible to select the degree of difficulty by, for example, a beginner mode, an intermediate skill mode, an advanced mode, etc. instead of the direct setting of the oil zone or the dry zone, and the setting of the oil zone or the dry zone for each degree of difficulty is set for the beginner, intermediate, It can be set in advance and reflected in the simulation.

As described above, the virtual bowling simulation system according to the present invention realizes a virtual bowling simulation image in an entirely new way, except that a screen is installed in a conventional screen bowling system and an image is projected, and a virtual bowling lane and a bowling pin A virtual bowling video is connected to an actual lane so that an actual lane and a virtual lane can be connected naturally but a real bowling ball can pass through an actual lane to a video so that a user who enjoys virtual bowling can perform bowling In order to improve the realism and immersion of the sports, accurate sensing, quick and accurate ball spin calculation, and using it to naturally lead the movement of the actual bowling ball and the movement of the virtual bowling ball on the image More virtual Realism and immersion for the ring to play also the Advantages that can be improved.
