Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] First, the technical terms involved in the embodiments of this application will be explained: VR devices are simulation systems used to create and experience virtual worlds. The optical engine is the core optical display component in a VR device. It is responsible for converting image signals into visible optical images and projecting them into the user's eyes to enable the user's experience of the virtual world. The performance of the optical engine directly affects the display effect of the VR device. The host and optical engine have different pins, enabling power and DP signal transmission between them.

[0041] Optical modules are the key components of an optomechanic responsible for optical imaging, and different optical modules have different optical characteristics.

[0042] Screen type refers to the type of screen used in an optical engine. Different screen types differ in display characteristics and other aspects.

[0043] A pre-built firmware library is a database or storage area that stores firmware information for various hardware devices. It contains different versions of firmware for different types of hardware devices.

[0044] Firmware information includes the firmware version number, applicable device type, file size, update content, and other relevant information.

[0045] The target firmware is compatible with the target device and can be used to upgrade the target device to the latest or appropriate firmware version.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one component of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] Before introducing the solution proposed in this application, the relevant technologies will first be introduced: In related technologies, the host can read the EDID data of the optical engine via a DP cable or obtain the optical engine model information via a serial port to achieve pairing between the host and the slave, which has problems with poor flexibility and compatibility.

[0048] Based on this, embodiments of this application provide a novel method, device, medium, and product that obtains a unique identifier for the optical engine within a VR device through a communication channel with the VR device. This ensures that the obtained unique identifier for the optical engine accurately matches the optical engine in the VR device, avoiding display problems caused by confusion between unique identifiers of different optical engines. Based on an optical engine parameter library, the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine within the VR device are obtained according to the unique identifier. The optical engine parameters can be obtained through the optical engine parameter library, allowing for correct display adjustments during VR device use. Based on the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine within the VR device, a visual connection is established between the PC and the VR device, enabling the VR device to accurately display images sent from the PC based on the unique identifier of the optical engine. This eliminates image display problems caused by differences in the optical engine parameters, improves the display quality of the VR device, and provides users with a more realistic and comfortable visual experience.

[0049] Figure 1 A flowchart illustrating the multi-optical-mechanical automatic identification method provided in the embodiments of this application. Figure 1 Please see. Figure 1 In an exemplary embodiment, the provided multi-optical-mechanical automatic identification method is applied to a personal computer PC and may include the following steps: Step 101: Obtain the unique identifier of the optical engine within the VR device through the communication channel between the VR device and the VR device.

[0050] The PC sends a request command to the VR device to obtain a unique identifier for the optical engine via a communication channel. The PC receives feedback from the VR device regarding the request command, thus obtaining the unique identifier of the optical engine within the VR device. This feedback information, including the unique identifier of the optical engine within the VR device, ensures that the obtained unique identifier accurately matches the optical engine in the VR device, avoiding display problems caused by confusion between unique identifiers of different optical engines. Optionally, the VR device includes at least one of VR headsets, VR glasses, etc. Optionally, the optical engine includes optical modules and display-related components such as screens.

[0051] For example, a communication channel is established between the PC and the VR device via USB, resulting in a UCB communication channel. Then, the software program corresponding to the VR device runs on the PC. This VR device software program sends a request command to the VR device via the USB communication channel to obtain the unique identifier of the optical engine. Upon receiving the request command, the VR device reads the unique identifier of the optical engine within the VR device and sends it back to the PC software via the USB communication channel. The VR device software program receives and displays the unique identifier.

[0052] For example, the unique identifier is a 2-byte identifier. The 2 bytes include 16 bits, represented as bit0, bit1, bit2, bit3, bit4, bit5, bit6, bit7, bit8, bit9, bit10, bit11, bit12, bit13, bit14, and bit15. Specifically, bits 0, 1, 2, and 3 identify the screen type; bits 4 and 5 identify the bridge chip type; bits 6 and 7 identify the MCU type; bits 8, 9, 10, and 11 identify the ID of the left optical module; and bits 12, 13, 14, and 15 identify the ID of the right optical module.

[0053] Step 102: Based on the optical engine parameter library, obtain the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine in the VR device according to the unique identifier.

[0054] After obtaining the unique identifier of the optical engine within the VR device, this unique identifier is used as a query condition to search and match within a pre-established optical engine parameter database. The optical engine parameters corresponding to the unique identifier are then found. Subsequently, the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the unique identifier are extracted from these parameters. This provides data support for subsequent precise correction and optimization of the VR device's display, ensuring that the VR device can present high-quality and accurate images.

[0055] For example, the optical-mechanical parameter database is deployed on a cloud server. The PC establishes a connection with the cloud server via the Internet and sends the obtained unique optical-mechanical identifier to the cloud server. After receiving the unique identifier, the cloud server queries the optical-mechanical parameter database to find the optical-mechanical parameter corresponding to the unique identifier, and the cloud database transmits the optical-mechanical parameter back to the PC via the Internet.

[0056] Step 103: Based on the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine in the VR device, establish a visual connection between the PC and the VR device.

[0057] After obtaining the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine within the VR device, the PC preprocesses the image data to be sent to the VR device based on these parameters. Optionally, image data preprocessing includes at least one of the following methods: distortion correction based on distortion parameters, color correction based on chromatic aberration parameters, and resolution adjustment based on pixel density. The PC sends the processed image data to the VR device through a communication channel. Upon receiving the processed image data, the VR device displays it, thus establishing an effective visual connection between the PC and the VR device. This allows the VR device to accurately display the image sent by the PC based on the unique identifier of the optical engine, eliminating image display problems caused by differences in the optical engine parameters, improving the display quality of the VR device, and providing users with a more realistic and comfortable visual experience. Optionally, display problems include at least one of distortion and chromatic aberration.

[0058] The multi-optical engine automatic identification method provided in this application obtains the unique identifier of the optical engine within the VR device through a communication channel with the VR device. This ensures that the obtained unique identifier of the optical engine accurately matches the optical engine in the VR device, avoiding display problems caused by confusion between the unique identifiers of different optical engines. Based on an optical engine parameter library, the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine within the VR device are obtained according to the unique identifier. The optical engine parameters obtained through the optical engine parameter library allow for correct display adjustments during VR device use. Based on the distortion parameters, chromatic aberration parameters, and pixel density corresponding to the optical engine within the VR device, a visual connection is established between the PC and the VR device. This enables the VR device to accurately display the image sent from the PC based on the unique identifier of the optical engine, eliminating image display problems caused by differences in the optical engine parameters, improving the display quality of the VR device, and providing users with a more realistic and comfortable visual experience.

[0059] Figure 2 A flowchart illustrating the multi-optical-mechanical automatic identification method provided in the embodiments of this application. Figure 2 . Figure 2 exist Figure 1 Based on this, the automatic identification method for multiple optical machines is described in detail. In an exemplary embodiment, the method may include the following steps: In some exemplary embodiments, step 101 may further include: Step 1011: Send a first request message to the VR device through the communication channel between the VR device and the VR device. The first request message is used to request the VR device to obtain the unique identifier of the optical engine.

[0060] A first request message is sent to the VR device via the communication channel between the VR device and the VR device. The first request message is used to request the VR device to obtain the unique identifier of the optical engine.

[0061] For example, when the communication channel between the PC and the VR device is a Wi-Fi communication channel, the PC sends a first request message to the VR device via the Wi-Fi communication channel. The software program on the PC corresponding to the VR device generates a data packet containing a request to obtain the unique identifier of the optical engine according to a predetermined protocol, and sends the request data packet to the VR device through the Wi-Fi module. The VR device receives the request data packet and processes it accordingly.

[0062] Step 1012: Based on the VR device's response to the first request information, obtain the unique identifier of the optical engine within the VR device.

[0063] Based on the VR device's response to the first request, a unique identifier for the optical engine within the VR device is extracted from the response information. Through this unique identifier, the PC can accurately distinguish between different optical engines, enabling targeted operations based on the characteristics of each optical engine.

[0064] For example, after receiving the first request information, the VR device's processing module reads the unique identifier of the optical engine from the storage unit. Then, according to the communication protocol, it encapsulates the unique identifier into a response data packet and sends it back to the PC via the WIFI communication channel. The PC receives and parses the response data packet to obtain the unique identifier.

[0065] In some exemplary embodiments, the unique identifier includes the optical module of the optical engine and the screen type, and step 102 above may further include: Step 1021: Based on the optical engine parameter library, obtain the distortion parameters and chromatic aberration parameters corresponding to the optical engine in the VR device according to the optical module and screen type.

[0066] Based on the optomechanical parameter library, the optical module and screen type information obtained from the unique identifiers are used as query conditions to search for records in the parameter library that match both the optical module and screen type information. This yields the distortion and chromatic aberration parameters corresponding to the optomechanical system within the VR device. These distortion and chromatic aberration parameters are crucial for subsequent evaluation and correction of the optomechanical imaging quality.

[0067] Step 1022: Based on the optical engine parameter library, obtain the screen size and resolution corresponding to the optical engine in the VR device according to the screen type.

[0068] Based on an optical engine parameter library, and using the screen type obtained from unique identifiers as the query criterion, information matching the screen type is searched in the parameter library to obtain the screen size and resolution corresponding to the optical engine in the VR device. The screen size and resolution corresponding to the optical engine are of great significance for understanding the display capabilities of the optical engine and adapting it to different application scenarios.

[0069] For example, in a system that uses key-value pairs to store parameters, the screen type is stored as the key, and the screen size and resolution are stored as values. The program code retrieves the corresponding value from the key-value pair set based on the obtained screen type information, thus obtaining the screen size and resolution.

[0070] Step 1023: Based on the screen size and resolution, obtain the pixel density corresponding to the optical engine in the VR device.

[0071] Pixel density refers to the number of pixels per unit area, which reflects the level of detail in a screen display.

[0072] Based on the screen size and resolution information obtained in the steps, the pixel density corresponding to the optical engine in the VR device is calculated. This helps to evaluate the display clarity and precision of the optical engine and provides a reference for users to select suitable optical engine equipment or to carry out related application development.

[0073] In some exemplary embodiments, the multi-optical-mechanical automatic identification method further includes: Step A: Obtain the target device among the VR devices that needs to be upgraded.

[0074] By detecting the hardware devices in the VR device, the hardware devices in the VR device that require firmware upgrades are identified as target devices. A target device refers to a specific hardware device in the VR device that needs to be upgraded; optionally, the hardware device includes at least one key component such as an MCU and a bridge chip.

[0075] For example, in the system management software of a VR device, a device status monitoring module can be set up to periodically check the firmware version information of each hardware device. When a hardware device's firmware version is found to be lower than the preset latest version, that hardware device is marked as a target device.

[0076] Step B: Search for the firmware information corresponding to the target device in the preset firmware library to obtain the target firmware corresponding to the target device.

[0077] In the preset firmware library, the firmware information corresponding to the target device type and model information is found by querying or matching, based on the target device type and model information, so as to obtain the target firmware corresponding to the target device, ensuring the smooth operation of the target device and the normal operation of the upgraded target device.

[0078] Step C: Based on the target device and target firmware, generate and send the first firmware upgrade information to the VR device.

[0079] The first firmware upgrade information is a data packet or instruction set containing the target device and the target firmware, used to instruct the VR device to perform a firmware upgrade operation on the target device.

[0080] The target device and target firmware information are integrated, and first firmware upgrade information is generated according to a specific communication protocol and format. Then, the first firmware upgrade information is sent to the VR device through the communication channel between the PC and the VR device, initiating the VR device's firmware upgrade process. This allows the target device to update to the firmware version corresponding to the target firmware, improving the VR device's performance or fixing known issues in the VR device.

[0081] For example, the PC connects to the VR device via Bluetooth. The upgrade tool software on the PC encapsulates the target device's identification information and the target firmware file in a specific binary format to generate a first firmware upgrade information data packet. Then, it sends the data packet to the VR device via the Bluetooth communication interface. After receiving the data packet, the VR device parses out the target device and target firmware information and initiates the firmware upgrade process.

[0082] In some exemplary embodiments, the target device includes a microcontroller unit (MCU) and / or a bridge chip. The unique identifier includes the MCU type of the MCU and the bridge chip type of the bridge chip. The target device is obtained by searching for the corresponding firmware information in a preset firmware library. This includes: when the target device is an MCU, searching for the corresponding firmware information in the preset firmware library by MCU type to obtain the target firmware for the MCU; and / or, when the target device is a bridge chip, searching for the corresponding firmware information in the preset firmware library by bridge chip type to obtain the target firmware for the bridge chip.

[0083] When the target device is determined to be an MCU, the firmware information corresponding to the MCU type is searched in a preset firmware library to obtain the target firmware for the MCU. When the target device is a bridge chip, the bridge chip type is used as the search criterion to search for matching bridge chip firmware information in the firmware library to obtain the target firmware for the bridge chip. If the target device includes both an MCU and a bridge chip, the search is performed separately using the two methods described above to obtain the target firmware for each. By accurately and quickly finding the corresponding target firmware from the firmware library according to the different types of target devices, the efficiency and accuracy of firmware search are improved, ensuring that different types of devices can obtain suitable firmware for upgrades.

[0084] Figure 3 A flowchart illustrating the multi-optical-mechanical automatic identification method provided in the embodiments of this application. Figure 3 Please see. Figure 3 In an exemplary embodiment, the provided multi-optical-engine automatic identification method is applied to a VR device, wherein the host and optical engine within the VR device are pluggably connected, and may include the following steps: Step 301: The host receives and responds to the first request information sent by the PC, and generates the second request information.

[0085] The host unit is the core control device of a VR device.

[0086] The second request information is generated by the host based on the first request information sent by the PC and is prepared to be sent to the optical machine. It is used to request the optical machine to obtain a unique identifier.

[0087] After receiving the first request information from the PC, the host analyzes and processes it, generating a second request information according to preset logic and procedures. Through the host's response to the PC's first request information, a second request information for the optical engine is further generated, establishing an indirect communication bridge between the PC and the optical engine. This allows the PC to indirectly control the host to obtain the required first request information from the optical engine, enhancing the system's flexibility and controllability.

[0088] Step 302: Based on the communication channel between the host and the optical engine, the host sends a second request message to the optical engine. The second request message is used to request the optical engine to obtain the unique identifier of the optical engine.

[0089] The host computer uses a pre-established communication channel with the optical engine to send the generated second request information to the optical engine according to the corresponding communication protocol, which ensures the reliability and accuracy of the communication between the host computer and the optical engine, enabling the optical engine to correctly receive the host computer's request and respond accordingly.

[0090] Step 303: The optical engine receives and responds to the second request information and sends the optical engine's unique identifier to the host.

[0091] After receiving the second request information sent by the host, the optical engine reads the unique identifier from the optical engine's storage unit, encapsulates the unique identifier according to the communication format agreed with the host, and sends it to the host, providing a basis for the host to further process and use the unique identifier.

[0092] Step 304: The host receives the unique identifier of the optical engine and sends the unique identifier of the optical engine to the PC through the communication channel between the host and the PC.

[0093] After receiving the unique identifier sent by the optical engine, the host sends the unique identifier to the PC through the pre-established communication channel between the host and the PC, which facilitates users to perform device management, configuration and other operations, and improves the overall management efficiency and convenience of the system.

[0094] In one exemplary embodiment, the method may include the following steps: Step A: The host receives and responds to the first firmware upgrade information sent by the PC, and obtains the second firmware upgrade information corresponding to the first firmware upgrade information. The second firmware upgrade information is used to instruct the optical engine to upgrade the target device.

[0095] The host computer receives the first firmware upgrade information sent by the PC through a communication interface. The processor inside the host then analyzes and processes this information, generating corresponding second firmware upgrade information according to preset rules and the communication format agreed upon with the optical engine. This provides accurate instructions for subsequent firmware upgrades of the target device by the optical engine, enhancing the system's compatibility and scalability.

[0096] Step B: Based on the communication channel between the host and the optical engine, the host sends the second firmware upgrade information to the optical engine.

[0097] The host computer uses a pre-established communication channel with the optical engine to send the second firmware upgrade information to the optical engine according to the corresponding communication protocol. The upgrade command is sent to the optical engine accurately and timely through the specific communication channel, which ensures smooth communication between the host computer and the optical engine. This allows the optical engine to obtain the upgrade information in a timely manner, prepare for subsequent firmware upgrade operations, and improve the real-time performance and reliability of the system.

[0098] Step C: The optical engine receives and responds to the second firmware upgrade information, and upgrades the firmware of the target device to the target firmware.

[0099] After receiving the second firmware upgrade information from the host through its communication interface, the optical engine's internal processor analyzes and parses the information, identifying the upgrade instructions and related information. Then, based on this information, the optical engine retrieves the upgrade file from the designated location and replaces the target device's current firmware with the target firmware according to a preset upgrade process. This improves the target device's performance and stability, thereby enhancing the overall performance and reliability of the entire multi-optical engine system and providing users with a better experience.
