Referring to fig. 1, fig. 1 is a flowchart illustrating a terminal display device downloading data in a data interaction method of an AR/VR system. The method corresponding to fig. 1 is a flow that takes a terminal display device as an execution subject. In the embodiment of the present invention, preferably, the terminal display device performs data interaction with the AR/VR device after downloading and storing data in advance.

Specifically, the step of downloading data by the terminal display device includes: step S110 and step S120.

Step S110: and the terminal display equipment sends a login request to the computing equipment.

After the AR/VR system enters a use state, the terminal display device firstly logs in the computing device to obtain image data cache. The terminal display device enters a login state and sends a login request to the computing device in the login state.

Step S120: and the terminal display equipment receives an image data cache corresponding to the login request returned by the computing equipment, wherein the image data cache is data corresponding to a stereoscopic picture displayed by the terminal display equipment.

Each terminal display device has its own corresponding IP (internet protocol) address information, and after the terminal display device sends a login request to the computing device, the login request includes the IP address information of the terminal display device. Therefore, according to the IP address information contained in the login request, the terminal display equipment can receive the image data cache corresponding to the login request returned by the computing equipment. It can be understood that the image data cache received by the terminal display device matches the IP address information specific to the terminal display device itself. After the computing device receives the login request of the terminal display device, the computing device also receives the IP address information of the terminal display device contained in the login request. A plurality of image data caches are stored in a database of the computing device, each image data cache being marked by IP address information that matches the image data cache. Thus, according to the IP address information contained in the login request, the computing equipment matches the image data cache corresponding to the IP address information in the database. And after the image data cache is matched, the computing equipment sends the image data cache corresponding to the IP address information to the terminal display equipment. After the terminal display device receives the image data cache, the terminal display device caches and stores the image data.

First embodiment

The first embodiment of the invention provides a specific method for data interaction of an AR/VR system in a first control mode. The data interaction method in the first embodiment is implemented by using a terminal display device as an execution main body.

Referring to fig. 2, fig. 2 is a flowchart illustrating a terminal display device in a first control mode according to a first embodiment of the present invention. In this embodiment, the terminal display device controls the AR/VR device by closing the authority of the AR/VR device to acquire its own data and sending the data to the AR/VR device, so that the picture displayed by the AR/VR device is the same as the picture displayed by the terminal display device itself.

Specifically, the process of the terminal display device in the first control mode includes: step S210, step S220.

Step S210: and the terminal display equipment closes the authority of the AR/VR equipment to acquire the first image characteristic information in the stereoscopic picture displayed by the AR/VR equipment.

In this embodiment, the stereoscopic picture displayed by the AR/VR device may be a picture of a portion of a virtual stereoscopic space displayed by the AR/VR device. That is, in the virtual stereo space, with a certain position (for example, a camera viewpoint position) in the virtual stereo space as a first observation point, a picture that the first observation point presents in the virtual stereo space at a certain observation angle (viewing angle direction) may be a stereo picture displayed by the AR/VR device. The first image feature information of the stereoscopic picture displayed by the AR/VR device may include: the first observation point is positioned at the position in the virtual three-dimensional space, and corresponds to first position coordinate information. Meanwhile, the first image feature information may also include: the first observation point observes the center point of the partial picture of the virtual three-dimensional space presented at the position at a certain observation angle and the corresponding first visual angle coordinate information. The virtual stereo space may have a plurality of stereo pictures, and each stereo picture corresponds to one first image characteristic information, i.e. each first image characteristic information enables the AR/VR device to display a specific picture in the virtual stereo space. When the first perspective coordinate information is changed, the viewing angle of the first viewpoint is changed, and thus the AR/VR device causes the stereoscopic picture to be changed by the change of the display angle. When the first position coordinate information is changed, the observation position of the first observation point is also changed, so that the AR/VR device causes the stereoscopic picture to be changed by the change of the display position.

In the initial state of the operation of the AR/VR system, the authority of the AR/VR system default terminal display device for closing the AR/VR device to acquire the first image feature information in the stereoscopic picture of the AR/VR device is in the initial state. It can be understood that the terminal display device closes the authority of the AR/VR device to acquire the first image feature information in its own stereoscopic picture, that is, the terminal display device controls the controller in the AR/VR device to disconnect the coupling between the controller in the AR/VR device and the sampler in the AR/VR device, and the controller in the AR/VR device cannot receive the first image feature information sampled by the sampler in the AR/VR device. And the AR/VR acquisition permission is closed through the terminal display equipment, and the AR/VR equipment cannot acquire the first image characteristic information of the AR/VR equipment.

Preferably, to prevent the dizziness associated with using AR/VR devices. In this embodiment, when the AR/VR system is in the first control mode, the terminal display device only closes the authority of the AR/VR device to acquire the first position coordinate information in its own stereoscopic picture.

Step S220: and the terminal display equipment sends the second image characteristic information in the currently displayed stereo picture to the AR/VR equipment so that the AR/VR equipment synchronously displays the stereo picture.

The terminal display equipment controls the AR/VR equipment to acquire the authority of the first image characteristic information in the stereoscopic picture displayed by the AR/VR equipment to be in a closed state, and at the moment, the terminal display equipment can convert the second image characteristic information in the stereoscopic picture displayed by the terminal display equipment into a coordinate matrix through a converter and send the coordinate matrix to the AR/VR equipment.

As one mode, the stereoscopic picture displayed by the terminal display device may be a picture in which the terminal display device displays a part of a virtual stereoscopic space. In this embodiment, the virtual stereo space displayed by the terminal display device is the same as the virtual stereo space displayed by the AR/VR device. In the virtual three-dimensional space, a certain position (for example, a camera viewpoint position) in the virtual three-dimensional space is also used as a second observation point, and a picture displayed in the virtual three-dimensional space by the virtual second observation point at a certain observation angle (viewing angle direction) may be a three-dimensional picture. The second image characteristic information of the stereoscopic picture may be second position coordinate information corresponding to a position of the second viewpoint in the virtual stereoscopic space. Meanwhile, the second image feature information may also be second view coordinate information corresponding to a central point of a partial picture of the virtual three-dimensional space, which is observed at the position by the second observation point at a certain observation angle. Therefore, the virtual stereo space may have a plurality of stereo pictures, and each stereo picture corresponds to one second image characteristic information, i.e. each second image characteristic information enables the terminal display device to display a specific stereo picture in one of the virtual stereo spaces.

When the second viewing angle coordinate information is changed, the viewing angle of the second viewing point is changed, so that the terminal display device causes the stereoscopic picture to be changed by the change of the display angle. When the second position coordinate information is changed, the observation position of the second observation point is also changed, so that the terminal display device causes the stereoscopic picture to be changed through the change of the display position.

When the terminal display device displays the current stereoscopic picture, a sampler of the terminal display device can collect second image characteristic information generated by the current stereoscopic picture. Namely, the sampler of the terminal display device can collect the current second position coordinate information and the second view coordinate information.

After the terminal display device collects the current second position coordinate information and the second view angle coordinate information through the sampler of the terminal display device, the terminal display device can acquire the second position coordinate information and the second view angle coordinate information. The current second position coordinate information and the second view angle coordinate information of the sampler are input into the converter. The converter converts the second position coordinate information and the second view coordinate information into coordinate matrixes respectively through analysis. And the terminal display equipment converts the second position coordinate information and the second visual angle coordinate information into a coordinate matrix and sends the coordinate matrix to the AR/VR equipment.

One second image characteristic information corresponds to only one specific stereoscopic picture. The virtual stereo space displayed by the terminal display device is the same as the virtual stereo space displayed by the AR/VR device, and when the terminal display device and the AR/VR device both display stereo pictures through the same second image feature information, it can be understood that the terminal display device and the AR/VR device both observe at the same position and at the same observation angle in the virtual stereo space. Therefore, after the terminal display device converts the second image characteristic information into the coordinate matrix through the converter and sends the coordinate matrix to the AR/VR device, the AR/VR device can display the same stereoscopic picture as the terminal display device.

And continuously sending the current second image characteristic information to the AR/VR equipment through the terminal display equipment, and when the stereo picture displayed by the terminal display equipment changes to cause the relative change of the second image characteristic information, synchronously changing the second image characteristic information sent to the AR/VR equipment. Therefore, when the AR/VR system is in the first control mode, the current second image feature information is continuously sent to the AR/VR equipment through the terminal display equipment, and the stereo picture displayed by the AR/VR equipment is synchronized with the terminal display equipment.

In this embodiment, when the AR/VR system is in the first control mode, the terminal display device may close the permission of the AR/VR device to acquire the first position coordinate information of the AR/VR device. The terminal display device can control the AR/VR device to synchronously display the stereoscopic picture and the stereoscopic picture with the changed observation position according to the second position coordinate information and the change of the second position coordinate information.

In one specific implementation mode, the terminal display device only closes the authority of the AR/VR device to acquire the first position coordinate information in the stereoscopic picture of the terminal display device. Therefore, the terminal display equipment can also receive the first visual angle coordinate information returned by the AR/VR equipment. The terminal display device receives the coordinate matrix information of the first visual angle coordinate information returned by the AR/VR device, and the terminal display device analyzes the coordinate matrix information of the first visual angle coordinate information through the receiving matrix. When the analyzed first visual angle coordinate information is the same as the analyzed second visual angle coordinate information, the display visual angle of the three-dimensional picture displayed by the terminal display equipment is kept unchanged; when the analyzed first visual angle coordinate information is different from the analyzed second visual angle coordinate information, the terminal display equipment adjusts the first visual angle coordinate information to be the same as the received second visual angle coordinate information, and therefore the terminal display equipment can enable the display visual angle in the stereoscopic picture to be synchronous with the display of the AR/VR equipment.

Therefore, in the first control mode, the terminal display device can control the AR/VR device to synchronously display the stereoscopic picture with the same observation visual angle and observation position as the stereoscopic picture by sending the second position coordinate information and the second visual angle coordinate information to the AR/VR device. And the terminal display equipment can receive the first visual angle coordinate information returned by the AR/VR equipment, so that the observation visual angle in the stereoscopic picture displayed by the terminal display equipment can be synchronously changed along with the change of the observation visual angle in the stereoscopic picture displayed by the AR/VR equipment.

The first embodiment of the invention also provides a specific method for data interaction of the AR/VR system in the second control mode. The data interaction method in the second control mode takes the terminal display device as an execution subject.

Referring to fig. 3, fig. 3 is a flowchart illustrating the terminal display device in the second control mode in the first embodiment. In this embodiment, after the terminal display device logs in, the initial control state is the first control mode by default due to the AR/VR system. And the terminal display equipment enables the AR/VR system to enter a second control mode by starting the authority of the AR/VR equipment to acquire the data of the terminal display equipment. When the AR/VR system is in the second control mode, the terminal display device can not only send the second image characteristic information to the AR/VR device, but also receive the first image characteristic information sent by the AR/VR device, so that the terminal display device can synchronously display the same stereoscopic picture as the stereoscopic picture displayed by the AR/VR device.

Specifically, the process of the terminal display device in the second control mode includes: step S310, step S320.

Step S310: and the terminal display equipment opens the authority of the AR/VR equipment for acquiring the first image feature information in the stereoscopic picture displayed by the AR/VR equipment.

And the AR/VR system is in a second control mode, and the terminal display equipment opens the authority of the AR/VR equipment to acquire the first image feature information in the self stereo picture in the second control mode. The terminal display device opens the authority of the AR/VR device to acquire the first image feature information in its own stereoscopic picture, that is, the terminal display device controls the controller in the AR/VR device again, so that the controller in the AR/VR device is coupled with the sampler in the AR/VR device, and the controller in the AR/VR device can receive the first image feature information sampled by the sampler in the AR/VR device. The AR/VR acquisition permission is opened through the terminal display device, and then the AR/VR device can acquire first image feature information of the AR/VR device.

Step S320: and the terminal display equipment receives the first image characteristic information in the currently displayed stereoscopic picture returned by the AR/VR equipment and synchronously displays the stereoscopic picture.

And when the stereo picture displayed by the terminal display device changes, the second image characteristic information is relatively changed, and the second image characteristic information sent to the AR/VR device is also synchronously changed. Therefore, when the AR/VR system is in the second control mode, the current second image feature information is continuously sent to the AR/VR equipment through the terminal display equipment, and the stereo picture displayed by the AR/VR equipment is synchronized with the terminal display equipment. And the terminal display equipment can open the authority of the AR/VR equipment for acquiring the first position coordinate information of the AR/VR equipment.

Therefore, the terminal display equipment can also receive the first image characteristic information returned by the AR/VR equipment. And the terminal display equipment receives the first image characteristic information returned by the AR/VR equipment as the coordinate matrix information of the first visual angle coordinate information and the coordinate matrix information of the first position coordinate information. And the terminal display equipment analyzes the coordinate matrix information of the first visual angle coordinate information and the coordinate matrix information of the first position coordinate information through the receiving matrix.

After the analysis, the first visual angle coordinate information and the first position coordinate information in the first image characteristic information are the same as the second visual angle coordinate information and the second position coordinate information in the second image characteristic information, and the three-dimensional picture displayed by the terminal display equipment is kept unchanged; after the analysis, if any one of the first perspective coordinate information and the first position coordinate information in the first image feature information is different from any one of the second perspective coordinate information and the second position coordinate information in the second image feature information, the terminal display device adjusts the second image feature information to be the same as the received first image feature information, so that the terminal display device can synchronize the display of the displayed stereoscopic picture with the display of the AR/VR device.

Therefore, in the second control mode, the terminal display device can control the AR/VR device to synchronously display the stereoscopic picture with the same observation visual angle and observation position as the stereoscopic picture by sending the second position coordinate information and the second visual angle coordinate information to the AR/VR device. And the terminal display equipment can receive the first visual angle coordinate information and the second visual angle coordinate information returned by the AR/VR equipment, so that the observation visual angle and the observation position in the three-dimensional picture displayed by the terminal display equipment can change synchronously along with the change of the observation visual angle and the observation position in the three-dimensional picture displayed by the AR/VR equipment, and further, the observation visual angle and the observation position in the three-dimensional picture displayed by the terminal display equipment are synchronous with the first three-dimensional surface displayed by the AR/VR equipment.

Second embodiment

The second embodiment of the invention provides a specific method for data interaction of the AR/VR system in the first control mode. The method of data interaction in the second embodiment is implemented by using an AR/VR device.

Referring to fig. 4, fig. 4 is a flowchart illustrating the AR/VR device in the first control mode according to the embodiment. In this embodiment, after the AR/VR device obtains the image data cache, data interaction can be performed. In the first control mode, the authority of the AR/VR device for acquiring the data is closed by the terminal display device, so that the AR/VR device can receive the pictures sent by the terminal display device and synchronously display the pictures same as the terminal display device.

Specifically, the flow of the AR/VR device in the first control mode includes: step S410, step S420.

And step S410, the authority of the AR/VR equipment for acquiring the first image characteristic information in the stereoscopic picture displayed by the AR/VR equipment is closed by the terminal display equipment.

In the initial state of the operation of the AR/VR system, the authority of the AR/VR system for acquiescing the first image feature information in the stereoscopic picture of the AR/VR system is closed to the initial state by the terminal display device. It can be understood that the authority of the AR/VR device to acquire the first image feature information in its own stereoscopic picture is turned off by the terminal display device, that is, the controller in the AR/VR device is controlled by the terminal display device, the coupling between the controller in the AR/VR device and the sampler in the AR/VR device is disconnected, and the controller in the AR/VR device cannot receive the first image feature information sampled by the sampler in the AR/VR device. And the AR/VR acquisition permission is closed through the terminal display equipment, and the AR/VR equipment cannot acquire the first image characteristic information of the AR/VR equipment.

Preferably, to prevent the dizziness associated with using AR/VR devices. In this embodiment, when the AR/VR system is in the first control mode, the authority of the AR/VR device to acquire the first position coordinate information in its own stereoscopic picture is turned off by the terminal display device. That is, the sampler in the AR/VR device can transmit the sampled first view coordinate information to the controller in the AR/VR device.

Step S420, the AR/VR device receives the second image feature information in the stereoscopic picture currently displayed by the terminal display device and sent by the terminal display device, and synchronously displays the stereoscopic picture.

The AR/VR system is in a second control mode, and the AR/VR equipment receives second image characteristic information which is sent by the terminal display equipment and corresponds to the current display of the terminal display equipment continuously. The AR/VR equipment compares the received second image characteristic information with the first image characteristic information generated by the AR/VR equipment after analysis. And when the AR/VR equipment compares the analyzed second image characteristic information with the first image characteristic information of the AR/VR equipment, the analyzed second image characteristic information is the same as the first image characteristic information of the AR/VR equipment, so that the stereoscopic picture displayed by the AR/VR equipment is the same as the stereoscopic picture displayed by the terminal display equipment. When the AR/VR equipment compares the analyzed second image characteristic information with the first image characteristic information of the AR/VR equipment, the AR/VR equipment adjusts the first image characteristic information of the AR/VR equipment to be the same as the second image characteristic information, so that the AR/VR equipment adjusts the displayed stereoscopic picture to be the same as the stereoscopic picture displayed by the terminal display equipment again, and the stereoscopic picture displayed by the AR/VR equipment and the stereoscopic picture displayed by the terminal display equipment can be kept the same. Therefore, when the AR/VR system is in the first control mode, the AR/VR device continuously receives the second image characteristic information which is sent by the terminal display device and is currently used for displaying, and the stereo picture displayed by the AR/VR device is synchronized with the terminal display device.

In this embodiment, when the AR/VR system is in the first control mode, the AR/VR device is turned off only by the terminal display device for the right to acquire the first position coordinate information of the AR/VR device. The AR/VR device is capable of displaying a stereoscopic picture in synchronization with the display of the terminal display device and a stereoscopic picture with a change in the observation position. However, the AR/VR device only has the authority of acquiring the first position coordinate information in the self stereo picture and is closed by the terminal display device. Therefore, the AR/VR device can also transmit the first perspective coordinate information to the terminal display device. When the observation angle in the displayed stereoscopic picture of the AR/VR device is not changed, the first visual angle coordinate information and the second visual angle coordinate information sent to the terminal display device by the AR/VR device are the same, and at the moment, the display picture of the AR/VR device is kept the same as that of the terminal display device. When the observation angle in the displayed stereoscopic picture of the AR/VR equipment changes, the first visual angle coordinate information and the second visual angle coordinate information sent to the terminal display equipment by the AR/VR equipment are different. In this state, the AR/VR device can cause the terminal display device to adjust the display screen to be the same as the current display screen of the AR/VR device itself.

Therefore, in the first control mode, the AR/VR device can transmit the second position coordinate information and the second view angle coordinate information through the receiving terminal display device, thereby synchronously displaying a stereoscopic picture having the same viewing angle and viewing position as the stereoscopic picture. The AR/VR device can send the first visual angle coordinate information to the terminal display device, so that the observation visual angle in the stereoscopic picture displayed by the terminal display device can be synchronously changed along with the change of the observation visual angle in the stereoscopic picture displayed by the AR/VR device.

Referring to fig. 5, fig. 5 is a flowchart illustrating the AR/VR device in the second control mode in the second embodiment. In this embodiment, after the AR/VR device obtains the image data buffer, the initial control state is the first control mode by default due to the AR/VR system. And when the authority of the AR/VR device for acquiring the data is started by the terminal display device, the AR/VR system enters a second control mode. When the AR/VR system is in the second control mode, the AR/VR device can not only receive the second image characteristic information sent by the terminal display device, but also send the first image characteristic information to the terminal display device, so that the terminal display device can synchronously display the same stereoscopic picture as the stereoscopic picture displayed by the AR/VR device.

Specifically, the flow of the AR/VR device in the second control mode includes: step S510, step S520.

Step S510: and the authority of the AR/VR equipment for acquiring the first image characteristic information in the stereoscopic picture displayed by the AR/VR equipment is opened by the terminal display equipment.

And the AR/VR system is in a second control mode, and the authority of the AR/VR device for acquiring the first image feature information in the stereoscopic picture of the AR/VR device is opened by the terminal display device in the second control mode. The method can be understood that the authority of the AR/VR device to acquire the first image feature information in the stereoscopic picture of the AR/VR device is opened by the terminal display device, that is, the controller in the AR/VR device is coupled with the sampler in the AR/VR device in the secondary mode under the control of the terminal display device, and then the controller in the AR/VR device can receive the first image feature information sampled by the sampler in the AR/VR device and can send the first image feature information to the terminal display device.

Step S520: and the AR/VR equipment sends the first image characteristic information in the currently displayed stereoscopic picture to the terminal display equipment so that the terminal display equipment synchronously displays the stereoscopic picture.

The AR/VR system is in a second control mode, and the AR/VR equipment continuously receives the current second image characteristic information sent by the terminal display equipment. And the AR/VR equipment analyzes the received second image characteristic information to obtain coordinate matrix information of the second visual angle coordinate information and coordinate matrix information of the second position coordinate information. After the analysis, the second visual angle coordinate information and the second position coordinate information in the second image characteristic information are the same as the first visual angle coordinate information and the first position coordinate information in the first image characteristic information of the AR/VR equipment, and the three-dimensional picture displayed by the AR/VR equipment is kept unchanged; after the analysis, if any one of the second perspective coordinate information and the second position coordinate information in the second image feature information is different from any one of the first perspective coordinate information and the first position coordinate information in the first image feature information of the AR/VR device, the AR/VR device adjusts the first image feature information of the AR/VR device to be the same as the received second image feature information, so that the AR/VR device can synchronize the display of the displayed stereoscopic picture with the display of the terminal display device.

And the authority of the AR/VR equipment for acquiring the first position coordinate information of the AR/VR equipment is opened by the terminal display equipment. Therefore, the AR/VR device is also capable of transmitting the first image feature information to the terminal display device. When the stereo picture displayed by the AR/VR device changes, the first image characteristic information is relatively changed, and the first image characteristic information sent to the terminal display device is also changed synchronously. Therefore, when the AR/VR system is in the first control mode, the current first image feature information is continuously sent to the terminal display equipment through the AR/VR equipment, and the stereoscopic picture displayed by the terminal display equipment and the display of the AR/VR equipment are synchronous.

Therefore, in the second control mode, the AR/VR device can receive the second position coordinate information and the second view angle coordinate information sent by the terminal display device, so that the AR/VR device synchronously displays a stereoscopic picture with the same viewing angle and viewing position as the stereoscopic picture. And the AR/VR equipment can send the first visual angle coordinate information and the second visual angle coordinate information to the terminal display equipment, so that the observation visual angle and the observation position in the three-dimensional picture displayed by the terminal display equipment can change synchronously along with the change of the observation visual angle and the observation position in the three-dimensional picture displayed by the AR/VR equipment, and further, the observation visual angle and the observation position in the three-dimensional picture displayed by the terminal display equipment are synchronous with the first three-dimensional surface displayed by the AR/VR equipment.
