The present specification relates to a player position-based lighting directing method for a virtual reality game and a virtual reality system 1000 for performing the same.

Hereinafter, a virtual reality system 1000 according to an embodiment of the present specification will be described with reference to FIGS. 1 and 2 .

The virtual reality system 1000 is a system that provides virtual reality to a user. Here, virtual reality (VR) may mean an artificial environment provided by using visual and auditory information created by a computer program, unlike the real world.

Virtual reality is mainly a virtual reality that provides an image by creating a virtual space separated from reality by a program, and Augmented Reality (AR: Augmented Reality) that provides a single image by overlapping virtual images based on the real world ) and mixed reality (MR: Mixed Reality), which provides a virtual space by fusing the real world and virtual reality and provides an image for it, the term 'virtual reality' is It can be interpreted as virtual reality in a broad sense.

In the present specification, the virtual reality system 1000 may provide, for example, a video game made in virtual reality (hereinafter referred to as a 'VR game') to a user (hereinafter referred to as a 'player 3').

1 is a block diagram of a virtual reality system 1000 according to an embodiment of the present specification, and FIG. 2 is a schematic diagram of a virtual reality system 1000 according to an embodiment of the present specification.

1 and 2, the virtual reality system 1000 includes a head mounted display (HMD 1100: Head-Mounted Display), a game controller 1200, an auxiliary computing device 1300, a positioning module 1400, It may include a lighting module 1500 and a server 1600 .

The HMD 1100 is a device worn on the head of the player 3 and may function as an output interface for a user of a virtual reality service.

Mainly, the HMD 1100 may output visual information about the virtual environment, ie, a virtual image, to the player 3 . For example, the HMD 1100 may provide a 3D image to the player 3 through a stereoscopic display that outputs two images isolated from each other to both eyes of the wearer.

In addition, the HMD 1100 may include a speaker that selectively outputs a voice to output a voice related to the virtual environment to the wearer.

The HMD 1100 may function as a sensor for the wearer in addition to the above-described role as the output interface. For example, the HMD 1100 is equipped with a gyro sensor, an acceleration sensor, or the like, and the HMD 1100 can detect the movement of the user's head or the posture of the head using this.

In addition, a marker used for tracking the position, posture, and motion of the wearer's head by the positioning model of the virtual reality system 1000 may be installed on the exterior of the HMD 1100 .

The game controller 1200 functions as an input interface for a user of the virtual reality service.

The game controller 1200 is mainly provided in a stick shape or a gun shape as shown in FIG. 2 and can be gripped by the player 3 .

The game controller 1200 may include an operation button for receiving an operation of the player 3 . For example, the player 3 may fire a gun in the virtual space through an operation button of the game controller 1200 .

In addition, the game controller 1200 may include a gyro sensor or an acceleration sensor that detects the posture of the game controller 1200 adjusted according to the manipulation of the player 3 . For example, the player 3 may adjust the firing direction of the gun in the virtual space by adjusting the posture of the game controller 1200 .

In addition, a marker used for tracking the position, posture, motion, etc. of the game controller 1200 by the positioning model of the virtual reality system 1000 may be installed on the exterior of the game controller 1200 .

The positioning module 1400 may measure the position of the player 3 or the game controller 1200 in real space.

The virtual space in the VR game may be matched with the playground 1, which is a real space in which the VR game is performed. For example, in the real space, the player 3 plays the playground 1 on the When positioned, the virtual reality system 1000 sets the character (hereinafter referred to as 'player 3 character' or 'avatar') controlled by the player 3 to a virtual position corresponding to the position on the playground 1 in the virtual space. , or when the player 3 moves on the playground 1, the avatar can also be moved in the virtual space.

As such, the positioning module 1400 may position the player 3 or the game controller 1200 as basic information for the virtual reality system 1000 to process the avatar in the virtual space.

The positioning module 1400 may be, for example, a camera that tracks a marker installed in the player 3 in the playground 1 , the HMD 1100 , or the game controller 1200 . Here, the camera is a concept including all infrared cameras and thermal cameras, including RGB cameras, and the positioning module 1400 may be implemented in various forms other than the camera.

The positioning module 1400 may be installed in the structure 2 around which the playground 1 is disposed so as to have an angle suitable for imaging the player 3 in the playground 1 .

The auxiliary computing device 1300 and the server 1600 may perform various calculations and information processing for realizing virtual reality. For example, they process the various information detected by the positioning module 1400, the HMD 1100, and the game controller 1200 to determine the position, posture, motion, and motion of the player 3 or the game controller 1200, the player 3 The visual/auditory information that forms the virtual reality is generated by calculating the viewing angle of the .

1 and 2 , the auxiliary computing device 1300 and the server 1600 are illustrated as separate components, but in the virtual reality system 1000 , the auxiliary computing device 1300 is omitted and the auxiliary computing device 1300 is Functions may be integrated into the server 1600 or HMD 1100 .

However, in the VR game service, real-time audiovisual feedback may be important to improve immersion. When using wireless communication between the server 1600 and the HMD 1100, a delay time may occur, whereas the player 3 ) carried by the HMD 1100 and the auxiliary computing device 1300 capable of being connected by wire to generate a VR image or voice and transmit it to the HMD 1100 by wire, there may be an advantage that low-delay audiovisual feedback is possible.

Here, the auxiliary computing device 1300 , the server 1600 , or the HMD 1100 having an arithmetic function may include a controller, and in this specification, the controller is a chip or processor that executes a computer program, various arithmetic and information processing. It can be interpreted as encompassing not only a hardware form such as an electrical circuit capable of performing the above, but also a software form or a form in which hardware and software are combined.

Meanwhile, it should be noted that operations performed by the virtual reality system 1000 in the methods according to embodiments of the present specification to be described below may be understood to be performed under the control of the above-described controller unless otherwise specified.

The lighting module 1500 may irradiate lighting on the playground 1 . For example, the lighting module 1500 may be installed to face the playground 1 on the structure 2 as shown in FIG. 2 . The lighting module 1500 may include a light for actually outputting light, a motor for controlling the irradiation direction of the light, and a posture sensor for detecting the irradiation direction of the light, and according to a control signal from the server 1600 , a posture sensor and a motor The irradiation direction of the light is adjusted according to the operation of , and the light can be irradiated to any point on the playground 1 by outputting the light in a specific direction.

On the other hand, since the player 3 is wearing the HMD 1100, it is not possible to recognize that the lighting is being produced in the real space, so the production of lighting by the lighting module 1500 is performed by the player 3 who proceeds with the VR game. The aspect for the audience of VR games is strong.

It should be noted that the above-mentioned components of the virtual reality system 1000 may transmit/receive data to and from each other through a communication unit.

Hereinafter, a lighting directing method according to an embodiment of the present specification will be described. Here, the lighting direction method can be interpreted as a comprehensive concept encompassing not only the method of actually directing the lighting, but also the method of setting the lighting location as an initial work for this, and mainly interpreted as a lighting production method based on the player location for virtual reality games. It can be, but it is not necessarily for games. In addition, the operations performed in the following description should be understood as being performed by the virtual reality system 1000 , particularly the server 1600 , unless otherwise indicated as being performed by other components or otherwise clear from the context. will be.

As described above, the virtual reality system 1000 according to the embodiment of the present specification may produce various lights through the lighting module 1500 irradiating the lights onto the playground 1 .

In the present specification, the lighting module 1500 may be installed on a structure 2 constructed mainly around the playground 1 to dynamically produce lighting throughout the playground 1, this lighting In order for the module 1500 to produce lighting at a desired point of the playground 1, the installation position of the lighting module 1500 and the irradiation posture of the lighting module 1500 must be accurately known. However, depending on the size or shape of the playground 1, the shape or size of the structure 2 is not always constant, and the installation location of the lighting module 1500 also needs to be customized for each playground 1 in many cases. In order to produce precise lighting, it may be necessary to calculate the installation position or posture of the lighting module 1500 .

First, an example of a lighting position setting method according to an embodiment of the present specification will be described below.

3 is a flow chart of an example of a lighting position setting method according to an embodiment of the present specification.

Referring to Figure 3, the lighting position setting method according to an embodiment of the present specification includes the steps of detecting the player position (S1100), obtaining posture information from the player 3 toward the lighting module 1500 (S1200) and It may include calculating the lighting position based on the posture information (S1300).

Hereinafter, each step of an example of a lighting position setting method according to an embodiment of the present specification will be described with reference to FIGS. 4 and 5 .

4 is a view related to the acquisition of posture information in the lighting position setting method of FIG. 3, and FIG. 5 is a view related to the lighting position calculation in the lighting position setting method of FIG.

First, the virtual reality system 1000 may detect a player position ( S1100 ). Here, the player position may mean a position where the player 3 is located on the playground 1 in the real world. In addition, the virtual reality system 1000 may periodically or continuously perform the detection of the player position to track the position of the player 3 at least during the VR service.

Detection of player position can be performed in a variety of ways, some examples of which are listed below.

As an example, the positioning module 1400 provided as a camera captures the playground 1 where the player 3 is located and transmits it to the server 1600 , and the server 1600 uses the image captured by the camera to capture the playground (1) The position of the player 3 on the top can be determined. In this case, the server 1600 may calculate the player position by recognizing the human shape from the image using a machine learning algorithm such as a traditional object recognition algorithm or deep learning. Exemplarily, the server 1600 detects a bounding box for the player 3 region in the image through an artificial neural network model that generates a bounding box for a human-shaped object, and a bounding corresponding to the player 3’s foot. Using the point that the bottom of the box is the same height as the ground of the playground (1), the captured image is converted into a top view with the playground (1) as the reference plane in consideration of the camera’s posture and position, and the player (3) on the playground (1) ) can be calculated.

Alternatively, the HMD (1100) or the game controller (1200), including the equipment worn on the player (3) prepares a marker, detects the marker from the image, and the playground (1) through the size, positional relationship, arrangement pattern of the marker, etc. ), it is also possible to detect the position where the player 3 is located.

In addition, an active element is prepared in the equipment worn by the player 3, and the position of the player 3 is calculated by detecting the signal, or an accelerometer or gyro sensor installed in the equipment worn on the player 3, etc. It is also possible for the server 1600 to receive the sensed value and to detect the position of the player 3 through this.

Next, the virtual reality system 1000 may acquire posture information facing the lighting module 1500 from the player 3 ( S1200 ). Here, when the VR service is started or the lighting positioning mode is started, the virtual reality system 1000 requests the player 3 to take a posture toward the lighting module 1500 from a point in the playground 1 (eg For example, a guide message output) can also be used. The virtual reality system 1000 may request to take a posture without designating a specific location or designating a separate location. Also, when there are a plurality of lighting modules 1500 in the virtual reality system 1000, a request to designate a specific lighting module 1500 (this request may be made as a visual output through the light of the corresponding lighting module 1500) can also do On the other hand, in the case of designating a specific place, an identifier recognizable to the naked eye by the player 3 is displayed at a specific place in the playground 1 or the player 3 is moved to a specific place on the playground 1 in the virtual image. Movable guides may be included.

When the player 3 takes a posture toward the lighting module 1500 on the playground 1 , the virtual reality system 1000 may acquire posture information at this time.

For example, the player 3 may aim the gun-type or stick-type game controller 1200 to face the lighting module 1500 as shown in FIG. 4 . At this time, the game controller 1200 may detect the posture of the game controller 1200 using a posture detection sensor such as a gyro sensor built in the game controller 1200, and the player 3 uses the lighting module 1500 Since it is an aiming state, the detected posture may be a direction from the player 3 toward the lighting module 1500 . Similarly, the player 3 may take a posture looking at the lighting module 1500 while wearing the HMD 1100 , and even at this time, the HMD corresponding to the direction from the player 3 toward the lighting module 1500 . It is also possible to detect the posture of (1100).

As another example, the positioning module 1400 in the form of a camera is a posture in which the player 3 aims the game controller 1200 toward the lighting module 1500 or the posture of the HMD 1100, or a specific posture of the player 3 ( For example, a posture pointing to the lighting module 1500 with a hand) is captured, and the server 1600 may calculate posture information from the captured image through a marker tracking or markerless tracking technique.

On the other hand, since the posture information is changed in real time unless the player 3 is stationary, it may be necessary to distinguish whether it corresponds to a posture facing the lighting module 1500 among the changed postures. Accordingly, for example, the virtual reality system 1000 may determine whether a specific posture is a posture toward the lighting module 1500 based on a user input, such as a manipulation button of the game controller 1200 being triggered. .

That is, the server 1600 may select and use the posture information at the point in time when the user input regarding the game controller 1200 is generated as the posture information toward the lighting module 1500 . Specifically, the server 1600 collects player position and posture information in real time, and when a user input through the game controller 1200 is detected during collection, the player position and posture information at the time is used to calculate the lighting position to be described later. It can be stored as the position of the player to be and the attitude information at that position.

Through the above-described steps S1100 and S1200, the virtual reality system 1000 may acquire the position of the player 3 and the direction in which the lighting module 1500 is located from the position, and using this, as shown in FIG. The position of the lighting module 1500 may be calculated. At this time, since only the direction of the lighting module 1500 can be known from the position of the player 3 with only the attitude information at the position of one player 3, at least two or more positions of position information are required to know the lighting position. And, in order to secure positioning accuracy with respect to the lighting position, it may be preferable that the positional information for each position is at least three as shown in FIG. 4 .

When a plurality of player positions and posture information for each position, that is, a direction toward the lighting module 1500 from the player positions are obtained, the virtual reality system 1000 may calculate a lighting position therefrom ( S1300 ).

Specifically, referring to FIG. 5 , the server 1600 generates a plurality of virtual straight lines extending from the positions of the plurality of players 3 in a common coordinate system at an angle according to the posture information corresponding to each position, and The intersection point may be calculated as the position of the lighting module 1500 .

When there are a plurality of lighting modules 1500, the positions of all lighting modules 1500 provided in the virtual reality system 1000 can be set on the server 1600 by repeating the above-described steps for each lighting module 1500. have.

On the other hand, in the above description, an ideal situation in which the player 3 accurately takes a posture toward the lighting module 1500 is assumed, but in an actual environment, there is a possibility that the aiming of the player 3 contains some error. Therefore, another example of a lighting position setting method according to an embodiment of the present specification will be described below.

6 is a flowchart of another example of a lighting position setting method according to an embodiment of the present specification.

6, the lighting position setting method according to an embodiment of the present specification includes the steps of detecting the player position (S2100), obtaining posture information from the player 3 toward the lighting module 1500 (S2200), It may include a step of evaluating the positioning reliability based on the posture information (S2300) and calculating the lighting position based on the posture information (S2400).

Hereinafter, each step of another example of the lighting position setting method according to the embodiment of the present specification will be described with reference to FIGS. 8 and 11 .

7 is a view related to the acquisition of posture information in the lighting position setting method of FIG. 6, FIG. 8 is a view related to positioning reliability evaluation in the lighting position setting method of FIG. 6, and FIG. 9 is the lighting position setting method of FIG. It is a view related to obtaining additional posture information in , and FIG. 10 is a view related to calculating the lighting position in the lighting position setting method of FIG. 6 .

The virtual reality system 1000 may detect a player position ( S2100 ). This step may be performed in the same manner as step S1100 described above, and thus a detailed description thereof will be omitted.

Next, the virtual reality system 1000 may obtain posture information facing the lighting module 1500 from the player 3 ( S2200 ). At this time, the posture information may be posture information for each position of a plurality of players similarly to an example of the method of lighting position seolmeong according to the embodiment of the present specification described above. However, in the above-described example, it is assumed that the player 3 faces the lighting module 1500 correctly, but in reality, as shown in FIG. 8 , the posture of the player 3 toward the lighting module 1500 is from the player position. It may have an angle and an error towards the lighting position.

In this way, if an error occurs between the player 3's attitude toward the lighting and the direction toward the lighting from the player 3, the intersection of the virtual straight line extending from the player's position according to the attitude information does not occur, so the correct lighting position is calculated. Can not.

Therefore, the lighting position can be calculated as a point in a direction that minimizes the error with the actual lighting module 1500 installed position using virtual straight lines instead of the intersection of the virtual straight lines, and the point is exemplarily the distance value of the virtual straight line. It may be a point at which the sum is minimized or a point at which an error value according to the least squares method is minimized as shown in FIG. 9 . Calculating a point having a minimum error as a lighting position may be applied to the above-described example as well as this example, and this calculation may be performed in the server 1600 or the like.

However, even if the minimum error point is calculated as the lighting position as described above, the error value may still be greater than or equal to the threshold value in some cases. In other words, when L1, which is an error value between the installation position of the actual lighting module 1500 shown in FIG. 9 and the lighting position calculated by the server 1600, is greater than or equal to a threshold value, lighting presentation to be described later may be inaccurate.

Therefore, in this example, the virtual reality system 1000 evaluates the positioning reliability based on the posture information (S2300), and when sufficient positioning reliability is obtained, the lighting position calculation and the calculated lighting position can be determined as the lighting position, , when the positioning reliability is low, it is possible to additionally request posture information about the player's position.

Here, the positioning reliability can be evaluated in various ways, and typically the server 1600 calculates a point having a minimum error according to the minimum distance or least squares method for virtual straight lines, and the distance value or the error value at this time is Based on the positioning reliability can be evaluated. That is, it may be determined whether the positioning is reliable or not depending on whether the corresponding value is above or below the threshold.

If it is evaluated that the positioning reliability is insufficient, the virtual reality system 1000 may additionally request the player 3 to take a pose, and thus may acquire additional player location and posture information as shown in FIG. 9 . When the additional information is obtained, the virtual reality system 1000 may re-evaluate the positioning reliability as described above, as shown in FIG. 10 .

The re-evaluation can be performed generally similar to the existing positioning reliability evaluation, but it is possible to change some points.

For example, since the number of virtual straight lines used for calculating the lighting position is changed when additional information is obtained, the number of distances to the virtual straight line of the point calculated as the lighting position is changed, so normalization, that is, normalizing is performed. can be For example, normalizing may be performed by using an average value instead of simply adding up distance values or error values.

On the other hand, when evaluating positioning reliability by additionally using additional information, it is possible not to use all of the virtual straight lines according to the posture information for each player position collected so far. This is to exclude such a virtual straight line from the positioning operation because a relatively large error may remain even if the number of virtual straight lines is increased when information with a large error is included among the collected information. Below are some examples.

For example, in calculating the lighting position, the lighting position may be calculated using only a predetermined number of virtual straight lines among a plurality of virtual straight lines. Here, the target virtual straight line (ie, the virtual straight line to be used for positioning) among the plurality of virtual straight lines is the minimum distance value or the minimum error value for the lighting position calculated using a predetermined number of virtual straight lines, or the virtual straight line of the values. It may be selected as a combination in which the average of the values is minimized. When the target virtual straight line is determined in this way, the calculation of the lighting position may also be performed using only the selected target virtual straight line.

If the positioning reliability is evaluated above a certain level, the virtual reality system 1000 may finally calculate the lighting position from the posture information for each player position (S2400), and as a result, an error L1 in the initial evaluation as shown in FIG. 10 . It is possible to calculate an illumination position with a smaller error L2.

Hereinafter, an example of a lighting directing method according to an embodiment of the present specification will be described with reference to FIGS. 11 and 12 .

11 is a flowchart of an example of a lighting directing method according to an embodiment of the present specification, and FIG. 12 is a view related to an example of lighting directing according to the lighting directing method of FIG. 11 .

Referring to Figure 11, the lighting directing method according to an embodiment of the present specification comprises the steps of calculating the lighting position (S3100), detecting the player position (S3200), controlling the lighting direction to face the player (3) (S3300) and may include a step (S3400) of directing the light to the player (3).

Here, since steps S3100 and S3200 can be fully understood based on the matters mentioned in the above-described lighting position setting method, detailed descriptions thereof will be omitted.

When the lighting location is set and the player location is tracked on the playground 1 , the virtual reality system 1000 may control the lighting direction of the lighting module 1500 so that the lighting is irradiated toward the player 3 ( S3300 ). ). Specifically, the server 1600 may calculate a direction or a lighting posture from the lighting module 1500 to the player 3 based on the lighting position and the player position, and transmit this to the lighting module 1500 . The lighting module 1500 may receive this signal, and accordingly, the motor may adjust the posture of the light so that the direction of the light is irradiated from the lighting module 1500 to the player 3 . At this time, the lighting module 1500 checks whether the light irradiation direction and the direction from the lighting position to the player position match directly or indirectly through the server 1600 using the attitude sensor frame mounted on the lighting module 1500 . Both directions can be matched.

When the lighting direction is toward the player 3 , the virtual reality system 1000 may direct lighting to the player 3 ( S3400 ).
