Virtual Reality (VR) is called virtual environment for short, and it utilizes computer simulation to generate a virtual world in three-dimensional space, providing simulation of sense organs such as vision for users, so that users can feel as if they are, and can observe things in three-dimensional space in time without limitation. When the user moves, the computer can immediately perform complex operation to return the accurate three-dimensional world image to generate the presence. The technology integrates the latest development of the technologies such as computer graphics, computer simulation, artificial intelligence, induction, display, network parallel processing and the like, and is a high-technology simulation system generated by the assistance of computer technology.
Several different virtual reality systems are currently available, which typically have a head mounted virtual reality image generator, motion controller, and motion or position detector. Referring to fig. 1, fig. 1 is a schematic diagram of a prior art virtual reality system (HTC Vive) that can be operated on a computer platform, wherein a virtual reality space is generated by at least two scanning laser generators 10, and a user can wear a virtual reality image generator 12 and move a handheld motion controller 14 in the virtual reality space. In detail, two scanning laser generators 10 can be disposed opposite to each other and respectively generate scanning laser sources, and the overlapping range of the scanning laser sources in the space forms a light chamber (lighthouse). The head mounted virtual reality image generator 12 and the motion controller 14 are provided with a plurality of light sensors at different positions, respectively, which can be used to detect the scanning laser light source when in the light room. According to the time difference of the scanning laser light source detected by each optical sensor on the virtual reality image generator 12 and the motion controller 14, the computing or processing module on the computer or on the virtual reality image generator 12 can compute the position, the motion, the posture, etc. of the user wearing the virtual reality image generator 12 and the motion controller 14, and can further generate the corresponding virtual reality image according to the position, the motion, the posture, etc. of the user.
The scanning laser light source of scanning laser generator 10 generally has an effective distance within which the light sensor can achieve good sensing accuracy. Generally speaking, the distance between two opposite scanning laser generators 10 is 5-10 meters, so as to form an optical room with a diagonal distance of 5-10 meters, which is a suitable size for a common household space. However, when the user has a larger usage space, the light chamber cannot be extended outward due to the sensing accuracy limitation of the light sensor, so that the user can experience the virtual reality only in a limited space and cannot obtain a more complete experience.
Therefore, it is necessary to develop a virtual reality system capable of extending a virtual reality space according to the size of a used space to solve the above problems.

Detailed Description
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a virtual reality system 2 according to an embodiment of the invention. As shown in fig. 2, the virtual reality system 2 includes at least two scanning laser generators 20 and a virtual reality image generator 22, wherein the scanning laser generators 20 can emit scanning laser sources S, and the scanning laser sources S emitted by the at least two scanning laser generators 20 can form a light chamber R in space. In practice, two scanning laser generators are used to generate scanning laser sources, which are opposite to each other and are staggered to form a light chamber, so that the two scanning laser generators are respectively located at two vertexes of a diagonal line of the light chamber. The virtual reality image generator 22 may include a head mounted display 220 that may be worn on the head of the user to provide the user with virtual reality images, and a controller 222 that may be held by the user. A plurality of light sensors may be disposed on the surface of the head-mounted display 220 and the controller 222, and the light sensors may be used to receive the scanning laser light source S when the user wears the head-mounted display 220 and the controller 222 and is located in the optical chamber R.
The head-mounted display 220 has a processing module 2200 connected to the respective light sensors on the head-mounted display 220 and the controller 222, so as to obtain the time of scanning the laser light source S sensed by the respective light sensors on the head-mounted display 220 and obtain the time of scanning the laser light source S sensed by the respective light sensors on the controller 222 from the controller 222. According to the time for scanning the laser light source S sensed by each of the optical sensors, the processing module 2200 may calculate the first position of the virtual reality image generator 22 in the optical chamber R, that is, the first position of the user wearing the head mounted display 220 and the controller 222 in the optical chamber R, and the processing module 2200 may also calculate the posture of the user according to the time for scanning the laser light source S sensed by each of the optical sensors. The processing module 2200 controls the head mounted display 220 to generate and provide the virtual reality image to the user according to the calculated first position and posture of the user. In the embodiment, the processing module 2200 is located in the head-mounted display 220 and communicates with the controller 222 to receive the data of the optical sensor from the controller 222 through a wireless transmission technology, however, the implementation is not limited to the above-mentioned connection structure. For example, the processing module may be disposed in an external electronic processing device, such as a computer, and receive data of the light sensor from the head-mounted display and the controller by a wired or wireless transmission technology.
In this embodiment, each scanning laser generator 20 further includes a mobile device 200, such as a motor-driven tire or a track set, and the mobile device 200 can also communicate with the processing module 2200 through a wireless transmission technology and be controlled by the processing module 220 to drive the scanning laser generator 20 to move. The processing module 2200 may control the moving device 200 of each scanning laser generator 20 to move in the same direction and at the same speed, so that the optical chamber R may move in one direction while maintaining the original shape.
When the user wears the head-mounted display 220 and the controller 222 and performs various actions in the optical chamber R, the processing module 2200 may determine the posture and the first position of the user, so as to provide a virtual reality image for the user, so that the user can interact in the virtual reality image, and the user is located at a second position in the virtual reality image, generally speaking, the second position has a corresponding relationship with the first position. In practice, the accuracy of the pose and position is higher when the relative position between the optical sensor and the scanning laser generator is closer, and thus the accuracy of the virtual reality image is higher. In the case where the plurality of scanning laser generators form the optical chamber, the optical sensor has a high accuracy in a specific region of the optical chamber, such as the center of the optical chamber; in contrast, the light sensor may have a reduced sensing accuracy when it is close to the edge of the light chamber, which may distort the virtual reality image or may not be able to match the user's posture or movement.
In this embodiment, the processing module 2200 may control each of the moving devices 200 to move the scanning laser generator 20, so that the optical sensor maintains high accuracy. Specifically, the processing module 2200 determines a relative relationship between the first position and the optical chamber R according to the calculated first position of the virtual reality image generator 22 and the user in the optical chamber R, and controls the movement of the scanning laser generator 20 according to the relationship.
Referring to fig. 2 and 3, fig. 3 is a schematic diagram illustrating the virtual reality system 2 of fig. 2 determining a relative relationship between the first position and the optical chamber R and controlling the movement of the scanning laser generator 20 according to the relationship. As shown in FIG. 3, the light chamber R may be bounded inwardly by a threshold V of distance that may be stored in the processing module in practice. The user can wear the virtual reality image generator 22 to move in the optical chamber R, and when the distance between the first position and the boundary of the optical chamber R is smaller than the threshold V, the processing module can send a control signal to the mobile device 200 of the scanning laser generator 20, so that the mobile device 200 can drive the scanning laser generator 20 to move, and the optical chamber R can move relatively until the distance between the first position and the boundary of the optical chamber R is greater than the threshold V. In this embodiment, the distance between the virtual reality image generator 22 and the right boundary of the optical chamber R is smaller than the threshold V, so the processing module can send the control signal to make the mobile device 200 drive the scanning laser generator 20 to move rightward until the distance between the virtual reality image generator 22 and the right boundary of the optical chamber R is larger than the threshold V. Therefore, the optical chamber R can be matched with the movement of a user, the virtual reality range is substantially increased, and the accuracy of the optical sensor is maintained.
In addition, referring to fig. 2 and 4 together, fig. 4 is a schematic diagram illustrating the virtual reality system 2 determining a relative relationship between the first position and the optical chamber R and controlling the movement of the scanning laser generator 20 according to the relationship according to another embodiment of the invention. As shown in fig. 4, the present embodiment is different from the previous embodiment in that the present embodiment sets a predetermined region P in the optical chamber R, which can be stored in the processing module in practice and can be a region with higher optical sensor accuracy. The user can wear the head-mounted display 220 and the controller 222 to move in the optical chamber R, and when the distance between the first position and the boundary of the optical chamber R is smaller than the threshold V, the processing module can send a control signal to the moving device 200 of the scanning laser generator 20, so that the moving device 200 can drive the scanning laser generator 20 to move, and further the optical chamber R moves relatively until the first position is located in the predetermined region P. In this embodiment, the position above the virtual reality image generator 22 exceeds the predetermined region P, so the processing module can send a control signal to make the mobile device 200 drive the scanning laser generator 20 to move upward until the virtual reality image generator 22 is located in the predetermined region P again. Therefore, the optical chamber R can be matched with the movement of a user, the virtual reality range is substantially increased, and the accuracy of the optical sensor is maintained. In addition, according to another embodiment of the present invention, the processing module may also send a control signal to make the optical chamber R relatively move until the first position is located in the predetermined region P when the first position is determined not to be within the predetermined region P, so as to constantly maintain the virtual reality image generator 22 located in the predetermined region P with high accuracy of the optical sensor.
In addition, the processing module may also store the threshold V and the predetermined area P of the above embodiment, and determine the relative relationship between the first position and the optical chamber R by using the threshold V and the predetermined area P to control the movement of the scanning laser generator according to the relationship. According to another embodiment, the processing module may also first determine whether the distance between the first position and the boundary of the optical chamber R is smaller than a threshold V, and when the distance is smaller than the threshold V, the processing module may send a control signal to enable the moving device 200 to drive the scanning laser generator 20 to move to the predetermined region P.
As mentioned above, the processing module can generate the virtual reality image according to the virtual reality image generator and the first position of the user, and the user is located at the second position in the virtual reality image, and there is a corresponding relationship between the first position and the second position. However, in the above embodiment, since the optical chamber R is also moved, the first position calculated after the movement of the optical chamber R will be different from the position of the user after the movement in the real space, and the second position of the user in the virtual reality image will be shifted. In another embodiment, the processing module may further include a correction program for correcting the first position. In detail, the movement of the optical chamber R, i.e. the movement of the scanning laser generator 20, is relative to the user and the virtual reality image generator 22, so that the actual first position can be obtained by subtracting the calculated first position from the moving direction and distance of the scanning laser generator 20 in the calibration process.
Referring to fig. 5 and fig. 2 together, fig. 5 is a flowchart illustrating steps of a virtual reality method according to an embodiment of the invention, where the method of fig. 5 is used in a virtual reality system, and the architecture of the system can refer to fig. 2, and thus is not described herein again. As shown in fig. 5, the virtual reality method of the present embodiment includes the following steps: in step S30, at least two scanning laser generators 20 respectively emit scanning laser sources S to form a light chamber R in space; in step S32, the virtual reality image generator 22 receives the scanning laser source S through a plurality of optical sensors disposed thereon; in step S34, the processing module 2200 of the virtual reality image generator 2 determines that the virtual reality image generator 2 is located at a first position in the optical chamber R according to the scanning laser source S received by the optical sensor, and generates a virtual reality image according to the first position, wherein in the virtual reality image, the virtual reality image generator 2 is located at a second position corresponding to the first position; in step S36, the processing module 2200 controls the moving device 200 of the scanning laser generator 20 to move according to the first position; and, in step S38, the processing module 2200 corrects the virtual reality image generator 22 to be located at the second position in the virtual reality image according to the moving distance of the scanning laser generator 20.
In this embodiment, the virtual reality image generator 22 of step S34 may include the head mounted display 220 and the controller 222 to be worn or held by a user, and the light sensors are distributed on the surfaces of the head mounted display 220 and the controller 222. According to the time when each of the optical sensors receives the scanning laser light source S, the processing module 2200 may determine the first position of the user in the optical chamber R and the current posture of the user, and further control the head mounted display 220 to provide the virtual reality image of the user and enable the virtual reality image to interact with the user.
In step S36, the processing module 2200 may control the scanning laser generator to move according to the relative relationship between the first position and the optical chamber R. However, after the scanning laser generator moves, the second position shifts due to the difference between the first position of the optical chamber R and the first position of the optical chamber R before the movement, and thus the second position does not shift due to the correction. In step S38, the calculated first position may be subtracted from the moving distance of the scanning laser generator 20 to obtain an actual first position, and a second position in the virtual reality image generated according to the actual first position corresponds to the actual moving distance of the user without generating a drift.
In the above step S36, in practice, whether to move the scanning laser generator 20 and the moving direction and distance can be determined according to the relative relationship between the first position and the optical chamber R. Referring to fig. 6, fig. 6 is a flowchart illustrating steps of a virtual reality method according to another embodiment of the invention. As shown in fig. 6, after the virtual reality method of the present embodiment performs step S34, the method further includes: in step S360, the processing module 2200 determines whether the distance between the first position and the boundary of the optical chamber R is smaller than a threshold V; and, in step S362, when the distance between the first position and the boundary of the optical chamber R is determined to be smaller than the threshold V, the processing module 2200 controls the scanning laser generator 20 to move to the position where the distance between the first position and the boundary of the optical chamber R is larger than the threshold V. Other steps of the method of this embodiment are the same as those of the method of the previous embodiment, and therefore are not described herein again. The threshold V may be stored in the processing module 2200 in practice, and its value may be set by the user. In practice, the processing module 2200 may be configured to move all the control scanning laser generators 20 along the same direction and at the same speed, so that the optical chamber R does not deform during the movement, thereby avoiding affecting the calculation and determination of the first position in the optical chamber R.
In addition to the threshold V, the movement of the scanning laser generator may be controlled according to different conditions. Referring to fig. 7, fig. 7 is a flowchart illustrating steps of a virtual reality method according to another embodiment of the invention. As shown in fig. 7, after the virtual reality method of the present embodiment performs step S34, the method further includes: in step S364, the processing module 2200 determines whether the first position is outside a predetermined region of the optical chamber R; and, in step S366, when the first position is determined to be outside the predetermined region, the processing module 2200 controls the scanning laser generator 20 to move to the first position within the predetermined region. Other steps of the method of this embodiment are the same as those of the method of the previous embodiment, and therefore are not described herein again. The predetermined position may be stored in the processing module 2200 in practice, and the size and position thereof may be set by the user. If the preset position is set at a position with higher precision of the optical sensor, the method of the embodiment can continuously maintain the precision of the virtual reality image.
In addition, according to another embodiment, after the step S34 of the method, the processing module 2200 may also be performed to determine whether the distance between the first position and the boundary of the optical chamber R is smaller than the threshold V. When the distance is smaller than the threshold V, the processing module sends a control signal to move the scanning laser generator 20 to the preset region P under the driving of the moving device 200.
In summary, the virtual reality system and the virtual reality method of the present invention can effectively extend the maximum space of the virtual reality image when the available space is large, so that the user can not limit the movement of the optical chamber due to the size of the optical chamber. In addition, the user can not feel discontinuous abnormal movement of the virtual reality image through the correction program. Therefore, the user can obtain more complete virtual reality experience.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
