Description

Technical Field

[0001] The present application relates to the technical field of virtual reality head-mounted display devices, and in particular to a virtual reality head-mounted display device and a positioning device thereof. Background Art

[0002] Virtual Reality (VR) is a high-tech technology that has emerged in recent years. VR uses computer simulation to create a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, allowing users to feel as if they are actually there, and to observe things in the three-dimensional space in real time and without restrictions.

[0003] The spatial positioning function of existing VR devices (including helmets, controllers, etc.) is generally implemented separately using lighthouse spatial positioning or camera spatial positioning. Among them, lighthouse spatial positioning has more equipment and needs to set up base stations to obtain image information. It requires a large positioning space, but the positioning is accurate; while camera spatial positioning can only set up a camera on the VR headset to achieve spatial positioning. It has fewer equipment and requires less positioning space, but the positioning accuracy is poor and cannot meet the needs of users who have large changes in movements when playing games.

[0004] However, when users actually use VR headsets, their needs change in real time. When users want to enter games that require more precise positioning, lighthouse spatial positioning can better meet their needs; and when users are playing games that do not require high action and real-time dynamic tracking, camera positioning can meet their needs. This is obviously difficult to meet the needs of different users or different needs. Summary of the invention

[0031] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0032] Figure 1 : is an application scenario diagram of a virtual reality head display device provided by an exemplary embodiment of the present application. Figure 1 As shown, the virtual reality head display device 1 can be worn on the user's head to simulate a three-dimensional virtual world, provide users with simulations of senses such as vision, hearing, and touch, and make the user feel as if they are in the game. In order to achieve the positioning of the virtual reality head display device 1 (including the head-mounted device and the handle) worn by the user in the game, an image positioning module can be set on the virtual reality head display device 1 to obtain a spatial image, and determine the position information of the virtual reality head display device 1 based on the spatial image recognition processing. Alternatively, a base station set up indoors can be used to obtain the image information of the virtual reality head display device 1, and determine the position information of the virtual reality head display device 1 based on the image information recognition processing.

[0033] Figure 2 1 is a schematic diagram of the structure of a virtual reality head display device provided by an exemplary embodiment of the present application. Figure 2 As shown, the virtual reality head display device 1 includes: a host 2, a helmet 3, and a mask 4, wherein the helmet 3 is connected to the host 2, and the mask 4 is detachably connected to the helmet 3, and a positioning device is set to determine the position information of the virtual reality head display device 1, thereby providing the host 2 with the position information of the virtual reality head display device 1 to meet the game requirements.

[0034] Figure 3FIG. 1 is a schematic diagram of a positioning device for a virtual reality head display device provided by an exemplary embodiment of the present application. Figure 3 As shown, the positioning device is applied to the above-mentioned virtual reality head display device 1; wherein, the positioning device includes: an image positioning module 20, a laser positioning module 30 and a positioning mode switching module, wherein the image positioning module 20 is arranged on the helmet 3 and is in communication connection with the host 2, and the image positioning module 20 is used to obtain spatial image information and determine the position information of the virtual reality head display device 1 according to the spatial image information; the laser positioning module 30 includes a laser emitter 31 (such as Figure 1 ) and a laser receiver 32, wherein the laser transmitter 31 is arranged in the space where the virtual reality head display device is located, and the laser receiver 32 is arranged on the virtual reality head display device 1. Specifically, the laser receiver 32 is arranged on the mask 4, and the laser receiver 32 receives the laser signal emitted by the laser transmitter 31. The laser positioning module 30 determines the position information of the virtual reality head display device 1 according to the laser signal; the positioning mode switching module is connected to the image positioning module 20 and the laser positioning module 30 in communication, and the positioning mode switching module is used to select the image positioning module 20 and / or the laser positioning module 30 to determine the position information of the virtual reality head display device 1. Specifically, the positioning mode switching module is arranged on the mask 4, and the mask 4 is detachably connected to the helmet 3. When the mask 4 is connected to the helmet 3, the positioning mode switching module is connected to the host 2 in communication, and the positioning mode switching module can select the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0035] The laser positioning module 30 in the present application does not need to be provided with image acquisition devices such as cameras, but only needs to use a laser transmitter 31 and a laser receiver 32 to determine the position of a moving object. Specifically, when in use, two laser transmitters 31 are arranged at opposite corners of the room to form a rectangular area (e.g., 15 feet × 15 feet). It should be understood that this area can be adjusted according to the actual size of the space. The laser transmitter 31 includes two rows of fixed LED lights, which emit laser beams (e.g., 6 times per second). Each laser transmitter 31 is designed with two scanning modules, which respectively emit horizontal and vertical lasers to scan the positioning space in the horizontal and vertical directions. The helmet and the handle are provided with a laser receiver 32. When the laser scans, the helmet starts counting. After the laser receiver 32 receives the laser, the relationship between the position of the laser receiver 32 and the time of receiving the laser is used to calculate the accurate position relative to the laser transmitter 31, thereby determining the relative position of the laser receiver 32 and the laser transmitter 31. If the laser beam hits enough laser receivers 32 at the same time, a 3D model can be formed, so that not only the position of the helmet can be detected, but also the direction of the helmet can be captured. Laser positioning can achieve millimeter-level accuracy, with almost no delay and no fear of occlusion. It can still capture even if the handle is placed on the back or under the crotch. Laser positioning avoids the disadvantages of high complexity, high equipment cost, slow computing speed, and susceptibility to natural light based on image processing technology, while also achieving high precision, high response speed, high stability, and can be implemented in any size space.

[0036] The image positioning module 20 in the present application has lower requirements for the positioning space and does not require additional auxiliary devices (such as laser transmitters, etc.) to be set up indoors. It only needs to be set on the helmet 3 (specifically, the front end of the helmet 3) to capture image information of the user's head and handle. After obtaining the image information, the image information is recognized and processed to determine the position information of the virtual reality head display device 1, so that the spatial positioning of the virtual reality head display device 1 can be simply and conveniently achieved.

[0037] Considering the advantages of the image positioning module 20 such as simplicity, convenience, and low cost, and the disadvantages of low positioning accuracy, and also considering the advantages of the laser positioning module 30 such as high positioning accuracy and fast response speed, and the disadvantages of complex structure and high cost, the present application designs a positioning device that can take into account two positioning methods (corresponding to two groups of positioning modules) at the same time, that is, freely switching between the two positioning methods according to the needs, so as to combine the advantages of the two positioning methods and avoid the disadvantages of realizing a single positioning method, thereby meeting the different needs of users. Specifically, the laser positioning module 30 is arranged on the mask 4, and the image positioning module 20 is arranged on the helmet 3. The mask 4 and the front end of the helmet 3 can be separated. When the user needs to use the positioning laser positioning function, the mask 4 can be covered on the helmet 3, and the positioning mode switching module can be started to select the laser positioning module 30 to realize the laser positioning function; when the user does not need to use the laser positioning function and the positioning mode switching module chooses to only select the image positioning module 20 to realize spatial positioning, the mask 4 can be separated from the helmet 3.

[0038] The present application provides a positioning device for a virtual reality head display device, which obtains spatial image information and determines the position information of the virtual reality head display device according to the spatial image information by setting an image positioning module on the helmet; and sets a laser positioning module, specifically, the laser positioning module includes a laser transmitter and a laser receiver, the laser transmitter is set in the space where the virtual reality head display device is located, the laser receiver is set on the virtual reality head display device, the laser receiver receives the laser signal emitted by the laser transmitter, the laser positioning module determines the position information of the virtual reality head display device according to the laser signal, and sets a positioning mode switching module that is communicatively connected with the image positioning module and the laser positioning module, the positioning mode switching module switches the two modules according to actual needs to independently realize the spatial positioning of the virtual reality head display device to meet the needs of different users or different games, and can also use the two modules at the same time to realize the spatial positioning of the virtual reality head display device to improve the positioning accuracy.

[0039] Figure 4 FIG. 1 is a schematic diagram of a positioning device for a virtual reality head display device provided by another exemplary embodiment of the present application. Figure 4 As shown, the mask 4 may include a first processor 131 and a connector 132, the connector 132 is detachably electrically connected to the host 2, the first processor 131 is communicatively connected to the laser receiver 32, the connector 132 is electrically connected to the host 2 to turn on the laser positioning module 30, and the first processor 131 is used to process the laser signal received by the laser receiver 32 to obtain the position information of the virtual reality head display device 1. By setting the connector 132, when the mask 4 is covered on the helmet 3, the connector 132 is electrically connected to the host 2 of the virtual reality head display device 1 to generate an electrical connection signal, and the host 2 turns on the laser positioning module 30 after receiving the electrical connection signal to switch to the laser positioning mode.

[0040] In one embodiment, the connector 132 may include an identity pin, which is detachably electrically connected to the host 2, and is used for the host 2 to identify the mask 4, and the identity pin is electrically connected to the host 2 to turn on the laser positioning module 30. By providing an identity pin (i.e., ID pin) on the connector 132, when the connector 132 is electrically connected to the host 2, the host 2 can confirm the identity of the connector 132 according to the identity pin of the connector 132, thereby avoiding erroneous operation caused by misconnection.

[0041] In one embodiment, the host 2 may include an identification module, which generates an electrical connection signal when the mask 4 is electrically connected to the helmet 3. The identification module receives the electrical connection signal to identify the mask type of the mask 4. When the mask type is identified as a spatial positioning mask, the identification module transmits the identification information to the host 2. The host 2 controls the positioning mode switching module to switch the positioning mode to the laser positioning mode according to the mask type.

[0042] An identification module can be set in the host 2 to identify the mask type. When the mask 4 is electrically connected to the helmet 3, an electrical connection signal is generated. After receiving the electrical connection signal, the identification module identifies the type of the mask 4. When the mask type is identified as a spatial positioning mask, the identification module transmits the identification information (characterizing that the mask type is a spatial positioning mask) to the host 2. The host 2 controls the positioning mode switching module to switch the positioning mode to the laser positioning mode according to the mask type, that is, starts the laser positioning module 30 to achieve positioning.

[0043] In one embodiment, when the host 2 recognizes that the mask 4 is a spatial positioning mask, the host 2 sends a switching mode instruction to the positioning mode switching module to control the positioning mode switching module to select the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0044] When the host 2 (identification module) recognizes that the mask 4 is a spatial positioning mask, the host 2 sends a switching mode instruction to the positioning mode switching module to control the positioning mode switching module to select the laser positioning module 30 to determine the position information of the virtual reality head display device 1, that is, when the host recognizes that the mask 4 is a spatial positioning mask, the positioning mode switching module is controlled to switch to the laser positioning mode.

[0045] In one embodiment, the connector 132 includes a first connection end, the helmet 3 includes a second connection end, the second connection end is electrically connected to the host 2, and the first connection end and the second connection end are detachably electrically connected. When the first connection end and the second connection end are electrically connected, the host 2 recognizes the mask 4 as a spatial positioning mask and controls the positioning mode switching module to select the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0046] The connector 132 includes a first connection end (e.g., a male end), and the helmet 3 includes a second connection end (e.g., a female end), wherein the first connection end is used in conjunction with the second connection end. When the first connection end is electrically connected to the second connection end, a level signal can be generated (e.g., the voltage of the second connection end is pulled to the same voltage as the first connection end, i.e., the voltage of the second connection end is changed). The host 2 identifies the mask 4 as a spatial positioning mask according to the voltage of the second connection end and controls the positioning mode switching module to select the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0047] In one embodiment, the positioning mode switching module includes a display screen. When the mask 4 is connected to the helmet 3, the display screen displays a prompt message for switching the positioning mode. The positioning mode switching module receives the switching mode instruction and selects the image positioning module 20 and / or the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0048] The positioning mode switching module may include a display screen. When the mask 4 is connected to the helmet 3, a prompt message for switching the positioning mode pops up on the display screen, indicating that a new positioning mode can be switched at this time. The positioning mode switching module receives the switching mode instruction (which can be manually input by the user or an electrical signal generated when the mask 4 and the helmet 3 are connected) and selects one of the image positioning module 20 and the laser positioning module 30 alone or both to determine the position information of the virtual reality head display device 1 simultaneously.

[0049] In one embodiment, the positioning mode switching module includes a switching button, and the user clicks the switching button to input the switching mode instruction; or the display screen includes a touch screen, and the user touches the touch screen to input the switching mode instruction.

[0050] When a prompt message for switching the positioning mode pops up on the display screen, the user can input a switching mode instruction by clicking a switching button or touching the touch screen to control the positioning mode switching module to select one of the image positioning module 20 and the laser positioning module 30 alone or both to determine the position information of the virtual reality head display device 1.

[0051] In one embodiment, the host 2 includes an identification module. When the mask 4 is connected to the helmet 3, the identification module identifies the mask 4 and generates an identification result. The host 2 sends a display instruction to the display screen according to the identification result. The display screen receives the display instruction and displays a prompt message for switching the positioning mode.

[0052] When the recognition module recognizes the type of the mask 4, the host 2 sends a display instruction to the display screen according to the recognition result, so as to control the display screen to pop up a prompt message for switching the positioning mode.

[0053] In one embodiment, the host 2 receives an input command from the user and sends a mode switching command to the positioning mode switching module to control the positioning mode switching module to select the laser positioning module 30 to determine the position information of the virtual reality head display device 1.

[0054] When the user inputs an instruction to the host 2 , the host 2 sends a mode switching instruction to the positioning mode switching module according to the input instruction, so as to control the positioning mode switching module to select the laser positioning module 30 .

[0055] In one embodiment, the laser receiver 32 may include a photosensitive sensor or a photoelectric sensor. By providing a photosensitive sensor or a photoelectric sensor, the laser signal can be accurately received, thereby achieving precise positioning. It should be understood that the embodiment of the present application can select different laser receivers 32 according to the requirements of the actual application scenario. As long as the selected laser receiver 32 can meet the requirements of laser positioning, the present application does not limit the specific type of the laser receiver 32.

[0056] In one embodiment, the helmet 3 may also include a connection port, which is connected to a computer via a data cable, and the connection port is connected to the computer to switch to PC-VR mode and turn on the laser positioning module 30. After receiving the electrical connection signal from the mask 4, the host 2 can remind the user that it has switched to the laser space positioning mode and can connect to the computer (PC); after the user gives a confirmation instruction, the virtual reality head display device 1 can enter the PC-VR mode; or the user still retains the original VR all-in-one mode and does not switch to the PC-VR mode. Among them, in the VR all-in-one mode, the content of the display screen is driven by the all-in-one CPU. When it is switched to the PC-VR mode, the helmet 3 is connected to the PC graphics card via a data cable, and the graphics card drives the screen, and the screen displays the content on the PC; when the user switches to the PC-VR mode, the laser positioning mode is turned on at the same time, and the laser signal received by the laser receiver 32 is transmitted to the first processor 131 on the mask 4 for processing, and finally the positioning problem of the virtual reality head display device 1 is realized in combination with the handle.

[0057] In one embodiment, the virtual reality head display device 1 includes a handle, and the handle is communicatively connected to the host 2; Figure 4As shown, the above-mentioned image positioning module 20 may include a camera 21 and a second processor 22 that are communicatively connected, the camera 21 is used to capture the user's head image and the handle image, and the second processor 22 is used to process the user's head image and the handle image captured by the camera 21 to obtain the position information of the virtual reality head display device 1. By setting the camera 21 and the second processor 22, the positioning of the virtual reality head display device 1 can be simply and conveniently achieved to meet the user's gaming requirements with low positioning accuracy. It should be understood that the first processor 131 and the second processor 22 in the present application can be two independent processors or a processor integrated together, and the present application does not limit the specific existence form of the first processor 131 and the second processor 22.

[0058] Figure 5 1 is a flowchart of a method for positioning a virtual reality head display device provided by an exemplary embodiment of the present application. The method for positioning a virtual reality head display device is applied to any of the positioning devices of the virtual reality head display device described above; Figure 5 As shown, the positioning method includes the following steps:

[0059] Step 510: Obtain a positioning mode switching instruction.

[0060] The positioning mode switching instruction indicates that the virtual reality head display device selects the image positioning module and / or the laser positioning module for positioning. The positioning mode switching instruction is obtained in real time to obtain the user's positioning requirements or the game's positioning requirements.

[0061] Step 520: According to the switching instruction, select the positioning module of the virtual reality head display device.

[0062] According to the acquired positioning mode switching instruction, the corresponding positioning mode is selected. Specifically, the positioning module corresponding to the selected positioning mode is turned on to perform spatial positioning using the corresponding positioning module.

[0063] The present application provides a virtual reality head display device and a positioning method thereof. An image positioning module is arranged on a helmet to obtain spatial image information and determine the position information of the virtual reality head display device according to the spatial image information; and a laser positioning module is arranged. Specifically, the laser positioning module includes a laser transmitter and a laser receiver. The laser transmitter is arranged in the space where the virtual reality head display device is located, and the laser receiver is arranged on the virtual reality head display device. The laser receiver receives the laser signal emitted by the laser transmitter. The laser positioning module determines the position information of the virtual reality head display device according to the laser signal. A positioning mode switching module is arranged to be communicatively connected with the image positioning module and the laser positioning module. The positioning mode switching module switches the two modules according to the positioning mode switching instruction to independently realize the spatial positioning of the virtual reality head display device to meet the needs of different users or different games. The two modules can also be used simultaneously to realize the spatial positioning of the virtual reality head display device to improve the positioning accuracy.

[0064] Figure 6 FIG. 1 is a flow chart of a positioning method for a virtual reality head display device provided by another exemplary embodiment of the present application. Figure 6 As shown, step 510 may include:

[0065] Step 511: Acquire the connection signal between the mask and the helmet.

[0066] When the mask 4 is electrically connected to the helmet 3, an electrical connection signal is generated.

[0067] Step 512: Determine a switching instruction to switch to the laser positioning mode according to the connection signal.

[0068] Specifically, the positioning mode switching instruction can be an electrical connection signal generated when the above-mentioned mask 4 is covered on the helmet 3 and connected to the host 2. When the host 2 receives the electrical connection signal, it obtains the instruction to switch the positioning mode to the laser positioning mode. When the host 2 does not receive the electrical connection signal (that is, the connection is disconnected), it obtains the instruction to switch the positioning mode to the image positioning mode.

[0069] Figure 7 FIG. 1 is a flow chart of a positioning method for a virtual reality head display device provided by another exemplary embodiment of the present application. Figure 7 As shown, step 520 may include:

[0070] Step 521: Turn on the laser transmitter.

[0071] Specifically, the laser emitter 31 is turned on (may be turned on manually) to emit a laser signal.

[0072] Step 522: Turn on the laser receiver.

[0073] Specifically, the laser receiver 32 is turned on (it can be turned on automatically or manually) to receive the laser signal emitted by the laser transmitter 31. It should be understood that the present application can choose the above-mentioned manual connection to turn on the laser receiver 32, or other opening methods can be selected, such as setting a positioning mode switching button, through which the user can flexibly switch the positioning mode; for example, automatically switch according to the positioning accuracy requirements of the game played by the user, specifically, the user can manually select the positioning accuracy for each game when it is played for the first time, or adopt the default positioning mode according to the needs of the game itself (the default positioning mode can be manually modified), so that the positioning mode can be automatically switched according to different games when the user plays the game.

[0074] Step 523: Determine the position information of the virtual reality head display device according to the laser signal.

[0075] The relative positions of the laser receiver 32 and the laser transmitter 31 are calculated based on the laser signal received by the laser receiver 32, and the position information of the virtual reality head display device carrying the laser receiver 32 is determined based on the relative positions of multiple laser receivers 32 and the laser transmitter 31.

[0076] It should be understood that the embodiments of the present application can select one of the image positioning mode and the laser positioning mode for separate positioning according to the needs of the actual application scenario, or can select the image positioning mode and the laser positioning mode to be turned on at the same time for positioning. As long as the selected positioning mode can meet the positioning needs of the game, the present application does not limit the specific positioning mode. Specifically, when the game has high requirements for spatial positioning accuracy, the image positioning mode and the laser positioning mode can be selected to be turned on at the same time to achieve comprehensive positioning, that is, image positioning and laser positioning are used at the same time to improve positioning accuracy, thereby further improving the gaming experience. In addition, when selecting one of the image positioning mode and the laser positioning mode, the other mode can also be turned on at the same time to perform positioning calibration on the selected positioning mode to avoid problems such as reduced positioning accuracy caused by failure of the selected positioning mode or other reasons.
