[0026] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0027] The following describes the wireless communication method, apparatus, computer device, and storage medium for an in-vehicle VR device according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0028] Figure 1 This is a flowchart of the wireless communication method for the in-vehicle VR device provided in the first embodiment of the present disclosure.

[0029] It should be noted that the execution subject of the wireless communication method of the vehicle-mounted VR device in the first embodiment of the present disclosure is the wireless communication device of the vehicle-mounted VR device, which can be implemented by software and / or hardware. The device can be configured in the server on the vehicle side. The wireless communication method of the vehicle-mounted VR device proposed in the first embodiment of the present disclosure will be described below with the server as the execution subject, and no limitation is made here.

[0030] like Figure 1 As shown, the wireless communication method of the vehicle-mounted VR device may include the following steps:

[0031] Step 101: Based on a preset vehicle-side millimeter wave module, receive millimeter wave information sent by a VR-side millimeter wave module in a vehicle-mounted VR device.

[0032] Millimeter waves are electromagnetic waves between microwaves and light waves. Usually, the millimeter wave frequency band refers to 30GHz-300GHz, and the corresponding wavelength is 1mm-10mm. Millimeter wave communication refers to communication using millimeter waves as a carrier for transmitting information. Due to the extremely high frequency of millimeter waves, they need to be aligned for communication. Therefore, in this disclosure, the position of the millimeter wave module is arranged in the roof.

[0033] It should be noted that the vehicle-side millimeter wave module can be a vehicle-side millimeter wave array antenna module, which can include multiple millimeter wave transmission channels and reception channels, such as a millimeter wave transmitter and a millimeter wave receiver to transmit and receive millimeter wave signals. The vehicle-side millimeter wave module can be installed on the top of the vehicle, and can be located in the center of the roof, without limitation.

[0034] Specifically, the millimeter wave transmitter and receiver in the vehicle-side millimeter wave module can adopt hemispherical radiation to capture the radiation signal corresponding to the millimeter wave information and obtain the millimeter wave information therein.

[0035] In the present disclosure, the vehicle-mounted VR device may be a VR head display.

[0036] The VR-side millimeter wave module can be a millimeter wave device on the vehicle-mounted VR device, such as a millimeter wave transmitter and a millimeter wave receiver. The VR-side millimeter wave module can also emit millimeter waves toward the roof of the vehicle in the form of hemispherical radiation.

[0037] Among them, the millimeter wave information can be the millimeter wave sent by the VR-end millimeter wave module in the vehicle-mounted VR device, wherein the millimeter wave can include camera data and IMU data (attitude data) obtained by the vehicle-mounted VR device.

[0038] In the present disclosure, 60GHz can be selected as the operating frequency. The higher the frequency, the less interference, but the power consumption will increase. Therefore, 60Gbps is selected to balance the power and channel interference. There are ready-made communication protocols at this frequency, and some communication protocols can reach a bandwidth of 27Gbps, so it can basically meet the resolution of 2.5k and the refresh rate of 90hz.

[0039] Optionally, after the in-vehicle VR device enters the car, the Bluetooth module of the in-vehicle VR device can be paired with the Bluetooth module of the vehicle. After the pairing is completed, the millimeter wave modules of both parties can be started separately for duplex communication, so that the in-vehicle VR device can transmit the generated data to the car computer via millimeter waves in real time.

[0040] Step 102: Determine the target display screen according to the millimeter wave information.

[0041] Among them, the target display screen can be the screen currently to be displayed in the in-vehicle VR device, that is, the screen finally presented to the user.

[0042] As a possible implementation method, the server can first determine the posture information and camera data contained in the millimeter wave information, and then parse each image in the camera data to determine the current position change information of the in-vehicle VR device.

[0043] Specifically, the gyro inertial measurement sensor on a VR device can obtain deviation data such as the VR device's angular velocity, acceleration, and pitch angle at various moments. Because the in-car environment is complex and in motion, the IMU gyro inertial measurement sensor can be used to collect posture information of the VR device at different moments. It should be noted that since VR devices are worn on the head, the posture information measured by the IMU can be used to characterize the user's head posture.

[0044] Camera data, that is, the image data captured by VR devices (VR glasses). It is understandable that since VR devices can continuously transmit image data to the vehicle-side millimeter wave module, the server can obtain multiple sets of images for calculation.

[0045] Optionally, the current VR device's position can be calculated using coordinate data of three-dimensional points, i.e., pixel points, in multiple sets of images. Specifically, a machine learning algorithm can be used to compare and analyze multiple sets of adjacent frames, and the current VR device, i.e., the user's movement, can be analyzed to determine the relative position of each frame.

[0046] Alternatively, a target base image, also known as a reference image, may be pre-set. The target base image may include multiple reference areas, such as a seat reference area, a window reference area, a door reference area, and so on, and each reference area includes the spatial coordinates and baseline of the calibration object (target). By comparing the image in the camera data with the target base image, the current position of the VR device, i.e., its spatial position within the vehicle, can be determined.

[0047] It should be noted that after obtaining the position change information and posture information, the server can use them as input parameters to determine the image processing strategy, also known as the change strategy. In other words, the position and posture of the VR headset can be determined through millimeter wave information.

[0048] Furthermore, the server may determine a current rendering strategy according to the position change information and the posture information, and then render the image based on the rendering strategy to generate a target display screen.

[0049] It should be noted that the rendering strategy is also the image processing strategy. Based on the currently determined position change information and posture information, the server can render the image in the camera data according to the target rendering strategy to generate the target display screen, so that the VR glasses can sense and track in real time, allowing users to obtain a better immersive experience.

[0050] Step 103: Send the target display image to the vehicle-side millimeter wave module, so that the vehicle-side millimeter wave module sends the target display image to the VR-side millimeter wave module.

[0051] It should be noted that when sending the target display screen to the VR device for display, the millimeter wave communication method can also be used, that is, the target display screen can be sent to the vehicle-side millimeter wave module to generate corresponding millimeter wave information, so that the VR-side millimeter wave module can process based on the received millimeter wave information to obtain the target display screen and divide it and distribute it to different displays for display.

[0052] In the disclosed embodiment, the server of the vehicle computer can receive millimeter wave information sent by the VR-end millimeter wave module in the vehicle-mounted VR device based on a preset vehicle-end millimeter wave module, and then determine the target display screen based on the millimeter wave information, and finally send the target display screen to the vehicle-end millimeter wave module, so that the vehicle-end millimeter wave module sends the target display screen to the VR-end millimeter wave module. In this way, millimeter waves can be used as a carrier for transmitting information for communication, which not only completes the wireless communication work of the vehicle-mounted VR device, but also realizes low-latency transmission of large amounts of data with the vehicle computer, meets the display requirements of VR devices with high refresh rates and high resolutions, and brings users a deep immersion effect.

[0053] Figure 2 4 is a flow chart of a wireless communication method for an in-vehicle VR device according to the second embodiment of the present disclosure.

[0054] like Figure 2 As shown, the wireless communication method of the vehicle-mounted VR device may include the following steps:

[0055] Step 201: In response to determining that the Bluetooth module preset in the vehicle is paired with the Bluetooth module in the vehicle-mounted VR device, the vehicle-side millimeter wave module is started.

[0056] It should be noted that Bluetooth modules can be deployed separately on the in-vehicle VR device and in the vehicle. When the in-vehicle VR device enters the vehicle, the Bluetooth module of the in-vehicle VR device will pair with the vehicle's Bluetooth module. After pairing, the millimeter wave modules of both parties will be activated for duplex communication, that is, the vehicle-side millimeter wave module will be activated. This can reduce energy loss before the in-vehicle VR device enters the vehicle.

[0057] Step 202: Based on the preset vehicle-side millimeter wave module, receive the millimeter wave information sent by the VR-side millimeter wave module in the vehicle-mounted VR device.

[0058] It should be noted that the specific implementation of step 202 can refer to the above embodiment and will not be described in detail here.

[0059] Step 203: In response to determining that the millimeter wave information contains posture information and camera data, the vehicle-side VR processor is controlled to enter a working state.

[0060] It should be noted that if the millimeter wave information contains posture information and camera data, it means that the current millimeter wave information is valid information and can be processed, thereby triggering the vehicle-side VR processor (vrlauncher) in the vehicle computer, and the vehicle-side VR processor can notify the corresponding processing unit to work.

[0061] Among them, the vehicle-side VR processor can be the VR display launcher in the car, that is, when the millimeter wave information containing posture information and camera data is received, the VR display launcher can start up.

[0062] Step 204: Determine the target display screen according to the millimeter wave information.

[0063] Step 205: Send the target display image to the vehicle-side millimeter wave module, so that the vehicle-side millimeter wave module sends the target display image to the VR-side millimeter wave module.

[0064] It should be noted that the specific implementation of steps 204 and 205 can refer to the above embodiment and will not be described in detail here.

[0065] In the disclosed embodiment, first, in response to determining that a preset Bluetooth module in the vehicle is paired with a Bluetooth module in the vehicle-mounted VR device, the vehicle-side millimeter wave module is activated. Then, based on the preset vehicle-side millimeter wave module, millimeter wave information sent by the VR-side millimeter wave module in the vehicle-mounted VR device is received. Then, in response to determining that the millimeter wave information contains posture information and camera data, the vehicle-side VR processor is controlled to enter an operating state. Then, based on the millimeter wave information, a target display screen is determined. Finally, the target display screen is sent to the vehicle-side millimeter wave module, so that the vehicle-side millimeter wave module sends the target display screen to the VR-side millimeter wave module. In this way, millimeter wave communication can be carried out after Bluetooth pairing, avoiding energy consumption caused by the millimeter wave module being in an operating state. In addition, the millimeter wave information contains posture information and camera data, and the vehicle-side VR processor is controlled to enter an operating state, so that the vehicle-side VR processor can be triggered to start and operate when the information is valid. Communication is carried out using millimeter waves as the carrier for transmitting information. This not only completes the wireless communication of the vehicle-mounted VR device, but also achieves low-latency transmission of large amounts of data with the vehicle computer, meets the display requirements of VR devices with high refresh rates and high resolutions, and brings users a deep immersive effect.

[0066] The third embodiment of the present disclosure also proposes a wireless communication system for an in-vehicle VR device, including a vehicle-side millimeter wave module and a VR-side millimeter wave module, wherein the vehicle-side millimeter wave module is arranged on the top of the vehicle, and the VR-side millimeter wave module is arranged in the in-vehicle VR device.

[0067] like Figure 3 As shown, Figure 3 Schematic diagram of the hemispherical radiation form of the vehicle-side millimeter wave module and the VR-side millimeter wave module.

[0068] like Figure 4 As shown, Figure 4 Schematic diagram of wireless duplex communication for in-vehicle VR devices.

[0069] The vehicle-side millimeter wave module includes a vehicle-side millimeter wave transmitter and a vehicle-side millimeter wave receiver, and the vehicle-side millimeter wave transmitter radiates toward the floor of the vehicle in a hemispherical radiation form;

[0070] The VR-end millimeter wave module includes a VR-end millimeter wave transmitter and a VR-end millimeter wave receiver, and the VR-end millimeter wave transmitter radiates toward the roof in a hemispherical radiation form.

[0071] The system includes a first Bluetooth module and a second Bluetooth module, wherein the first Bluetooth module is set on the vehicle side and the second Bluetooth module is set in the vehicle-mounted VR device.

[0072] In the disclosed embodiment, the server of the vehicle computer can receive millimeter wave information sent by the VR-end millimeter wave module in the vehicle-mounted VR device based on a preset vehicle-end millimeter wave module, and then determine the target display screen based on the millimeter wave information, and finally send the target display screen to the vehicle-end millimeter wave module, so that the vehicle-end millimeter wave module sends the target display screen to the VR-end millimeter wave module. In this way, millimeter waves can be used as a carrier for transmitting information for communication, which not only completes the wireless communication work of the vehicle-mounted VR device, but also realizes low-latency transmission of large amounts of data with the vehicle computer, meets the display requirements of VR devices with high refresh rates and high resolutions, and brings users a deep immersion effect.

[0083] Determining the attitude information and camera data contained in the millimeter wave information;

[0086] The image is rendered based on the rendering strategy to generate a target display screen.

[0087] In the disclosed embodiment, the server of the vehicle computer can receive millimeter wave information sent by the VR-end millimeter wave module in the vehicle-mounted VR device based on a preset vehicle-end millimeter wave module, and then determine the target display screen based on the millimeter wave information, and finally send the target display screen to the vehicle-end millimeter wave module, so that the vehicle-end millimeter wave module sends the target display screen to the VR-end millimeter wave module.
