[0002] With the development of science and technology, intelligence is becoming increasingly important for vehicles. Traditional car rearview mirrors can no longer meet consumer needs, and their limitations are becoming more and more obvious, especially when driving in rainy, foggy, nighttime, or even confined spaces. These conditions significantly restrict the driver's field of vision, posing a considerable challenge to driving safety.

[0003] Among related technologies, the development of electronic rearview mirrors can largely solve these pain points. The camera of an electronic rearview mirror has a more flexible viewing angle. The electronic rearview mirror can adjust the field of view in real time, and can freely switch between telephoto and wide-angle. It can also correct the distortion of video images, making the picture more intuitively presented to the driver. In addition, electronic rearview mirrors provide the driver with a wider range of road visibility, solving the problem of large blind spots and obstructed vision caused by the large size of the vehicle's own rearview mirrors.

[0004] However, during the design and development process, using only two cameras to achieve this function increases the overall vehicle development cost, which urgently needs to be addressed. Summary of the Invention

[0043] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0044] The following description, with reference to the accompanying drawings, describes a display method, apparatus, device, medium, and program product for an electronic rearview mirror according to embodiments of this application. Addressing the limitation of driving visibility in traditional rearview mirrors mentioned in the background art, this application provides a display method for an electronic rearview mirror. In this method, embodiments of this application acquire two current side video data streams from the vehicle using a camera, and transmit these two streams of side video data to an intelligent driving controller based on a first preset protocol. The intelligent driving controller decodes the two current side video data streams to obtain decoded side video data, and adjusts the ISP parameters of the decoded side video data based on a preset SOC processor to obtain adjusted side video data. The first side video data stream in the adjusted side video data stream is encoded to obtain an encoded video stream, and the encoded video stream is transmitted to the vehicle's electronic rearview mirror display screen for display via a second preset protocol. This solves the problem of limited driving visibility in traditional rearview mirrors, achieving a low-cost, wide-field-of-view electronic rearview mirror.

[0045] Specifically, Figure 1 This is a flowchart illustrating a display method for an electronic rearview mirror provided in an embodiment of this application.

[0046] like Figure 1 As shown, the display method of this electronic rearview mirror includes the following steps:

[0047] In step S101, the vehicle's current two-way side video data is collected by the camera, and the current two-way side video data is transmitted to the intelligent driving controller based on the first preset protocol.

[0048] Specifically, such as Figure 2 As shown, Figure 2 This diagram illustrates the transmission path and functional architecture of a camera image display method for an electronic rearview mirror according to one embodiment of this application. The application uses high-frame-rate cameras mounted on both sides of the vehicle to collect two channels of side video data in real time. These cameras, equipped with heating, HDR, and FLFM functions, act as the "eyes" of the electronic rearview mirror, recording image information during driving. The image information is then transmitted directly to the intelligent driving controller via the LVDS line using the GMLS2 protocol for image processing. This provides a reliable data input foundation for subsequent real-time image processing in the intelligent driving system.

[0049] In step S102, the intelligent driving controller decodes the current two-channel side video data to obtain the decoded two-channel side video data, and adjusts the ISP parameters of the decoded two-channel side video data based on the preset SOC processor to obtain the adjusted two-channel side video data.

[0050] Specifically, the intelligent driving controller uses a built-in MAX96712 deserializer to decode the two channels of GMSL2 protocol side video data received. The decoded video data is then transmitted to the ISP (Image Signal Processor) unit of the SOC processor via a CSI protocol channel. The ISP runs firmware to perform multi-dimensional parameter optimization on the video stream. Through the hardware decoding combined with the programmable ISP architecture, the entire process from data reception to processing and output is completed, effectively solving the problems of high processing latency and unstable image quality in traditional in-vehicle video systems.

[0051] It should be noted that, as Figure 3 As shown, Figure 3 This is a schematic diagram of the ISP parameter tuning process of an electronic rearview mirror display method according to an embodiment of this application. After the camera module (Lens) projects the light signal onto the photosensitive area of ​​the sensor (sensor), the sensor transmits the original image (Bayer format) to the ISP in the form of photoelectric conversion. After processing by the internal algorithm, the RGB spatial domain image is output to the back-end video acquisition unit.

[0052] Optionally, in some embodiments, the ISP parameters of the decoded two-channel side video data are adjusted based on a preset SOC processor, including: performing at least one of the following on the decoded two-channel side video data: black level correction, bad pixel correction, digital gain, automatic exposure control, automatic white balance, automatic focus, wide dynamic range, and dynamic range compression.

[0053] Optionally, in some embodiments, the ISP parameters of the decoded two-channel side video data are adjusted based on a preset SOC processor to obtain the adjusted two-channel side video data, including: acquiring the image information of the ISP logic of the decoded two-channel side video data; and adjusting the ISP parameters of the decoded two-channel side video data through interrupt-driven operation to obtain the adjusted two-channel side video data.

[0054] Understandably, in the ISP processing of the SOC processor, the raw image information of the two decoded side video data channels is first acquired. The ISP internally includes a CPU, GPU, IP, etc., and can process the transmitted image signals in real time. The ISP logic and the firmware running on the ISP work together to form the ISP. The ISP logic is responsible for completing part of the algorithm processing and statistically analyzing the real-time information of the image output. The firmware is driven by the video acquisition unit interrupt. The PQ Tools tool adjusts the online image quality of the ISP, obtains the image information from the ISP logic, and recalculates the image output quality to control the camera module, sensor, and ISP logic, completing automatic image processing. The ISP controls the lens and sensor through the firmware running on it, performing functions including Black Level Correction (BLC), Defective Pixel Correction (DPC), Digital Gain (Dgain), Auto Exposure (AE), Auto White Balance (AWB), Auto Focus (AF), and Wide Dynamic Range (WDL). The ISP parameters of WDR (Wide Range, WDR) and DRC (Dynamic Range Compression, DRC) are adjusted; the final output is two precisely adjusted side video data, which not only ensures processing efficiency, but also adaptively optimizes image quality according to the actual driving environment.

[0055] In step S103, the first side video data in the adjusted two-channel side video data is encoded to obtain an encoded video stream, and the encoded video stream is transmitted to the vehicle's electronic rearview mirror display screen for display through a second preset protocol.

[0056] Specifically, the first video stream from the two adjusted side video data streams is selected and input into a dedicated video encoder (such as the MAX96717 chip) for hardware encoding. This encoder uses a low-latency compression algorithm to convert the video stream into a data format that conforms to the GMSL3 protocol standard while maintaining image quality. The encoded video data is transmitted to the electronic rearview mirror displays on both sides of the vehicle via the GMSL3 protocol. The display receiver integrates a GMSL3 decoding module to restore the high-definition video signal in real time, ensuring visibility under different ambient light conditions.

[0057] Optionally, in some embodiments, after adjusting the ISP parameters of the decoded two-channel side video data based on a preset SOC processor to obtain the adjusted two-channel side video data, the method further includes: transmitting the second-channel side video data from the adjusted two-channel side video data to the intelligent driving perception module, so as to perform assisted driving actions through the intelligent driving perception module.

[0058] Understandably, after the SOC processor completes the ISP parameter optimization processing of the two side video data streams, the system directly transmits the second video stream to the intelligent driving perception module. This module can analyze target information such as vehicles, pedestrians, and obstacles in the video stream in real time and output structured perception data to the control system to realize intelligent driving functions and form a closed-loop control link from image acquisition to driving decision-making.

[0059] Optionally, in some embodiments, before acquiring the vehicle's current two-way side video data via the camera, the method further includes: adjusting the camera's frame rate to a preset frame rate and setting the camera at a preset position on the vehicle.

[0060] Understandably, the dual cameras are initialized and configured via the control bus, with their frame rate set to 60fps. The cameras are fixed to the traditional rearview mirror positions on both sides of the vehicle, and the installation angle is adjusted using professional calibration tools to ensure coverage of the field of view requirements stipulated by international standards. This establishes a standardized data input benchmark that meets the requirements of intelligent driving for subsequent video acquisition.

[0061] According to the electronic rearview mirror display method proposed in this application, this application embodiment acquires two current side video data of the vehicle through a camera, and transmits the current two side video data to the intelligent driving controller based on a first preset protocol; the intelligent driving controller decodes the current two side video data to obtain decoded two side video data, and adjusts the ISP parameters of the decoded two side video data based on a preset SOC processor to obtain adjusted two side video data; the first side video data in the adjusted two side video data is encoded to obtain an encoded video stream, and the encoded video stream is transmitted to the vehicle's electronic rearview mirror display screen for display through a second preset protocol. Thus, the problem of limited driving field of view in traditional rearview mirrors is solved, realizing a low-cost, wide-field-of-view electronic rearview mirror.

[0062] Next, the display device of the electronic rearview mirror according to an embodiment of this application is described with reference to the accompanying drawings.

[0063] Figure 4 This is a block diagram of the display device of the electronic rearview mirror according to an embodiment of this application.

[0064] like Figure 4As shown, the display device 10 of the electronic rearview mirror includes: a data acquisition module 100, a parameter adjustment module 200, and a display module 300.

[0065] The acquisition module 100 acquires the current two-way side video data of the vehicle through the camera, and transmits the current two-way side video data to the intelligent driving controller based on the first preset protocol.

[0066] The parameter adjustment module 200 decodes the current two-channel side video data to obtain the decoded two-channel side video data, and adjusts the ISP parameters of the decoded two-channel side video data based on the preset SOC processor to obtain the adjusted two-channel side video data.

[0067] The display module 300 encodes the first side video data in the adjusted two-channel side video data to obtain an encoded video stream, and transmits the encoded video stream to the vehicle's electronic rearview mirror display screen for display through a second preset protocol.

[0068] Optionally, before acquiring the current two-way side video data of the vehicle via the camera, the acquisition module 100 is also used to: adjust the frame rate of the camera to a preset frame rate and set the camera at a preset position on the vehicle.

[0069] Optionally, the parameter adjustment module 200 is specifically used to perform at least one of the following on the decoded two-channel side video data: black level correction, bad pixel correction, digital gain, automatic exposure control, automatic white balance, automatic focus, wide dynamic range, and dynamic range compression.

[0070] Optionally, the parameter adjustment module 200 is specifically used to: acquire the image information of the ISP logic of the decoded two-channel side video data; and adjust the ISP parameters of the decoded two-channel side video data through interrupt-driven operation to obtain the adjusted two-channel side video data.

[0071] Optionally, after adjusting the ISP parameters of the decoded two-channel side video data based on the preset SOC processor to obtain the adjusted two-channel side video data, the parameter adjustment module 200 is further configured to: transmit the second-channel side video data from the adjusted two-channel side video data to the intelligent driving perception module, so as to execute assisted driving actions through the intelligent driving perception module.
