[0027] Figure 1 This is a flowchart illustrating a camera data transmission method according to Embodiment 1 of this application. This embodiment is applicable to long-distance transmission of image data from vehicle-mounted cameras and can be executed by a camera data transmission system. This system can be implemented in hardware and / or software and can be configured in a computer device, such as a camera data transmission system within a vehicle-mounted server. The camera data transmission system includes a camera module, a data decoding module, a data encoding module, and a data receiving module. The camera module and the data decoding module are connected via differential signal transmission or coaxial cable transmission. The data decoding module and the data encoding module are connected via a high-speed serial or parallel interface. The data encoding module and the data receiving module are connected via differential signal transmission or coaxial cable transmission. Figure 1 As shown, the method includes:
[0028] S110. The initial image signal received by the target vehicle during driving is encoded for the first time by the camera module to obtain the target image differential signal, and the target image differential signal is sent to the data decoding module.
[0029] The camera module refers to the hardware component that captures images of the target scene and is responsible for generating the initial image signal; for example, the camera module can be an in-vehicle camera. The target vehicle refers to the vehicle for which image signal transmission is required. The initial image signal refers to the raw signal generated by the camera module when capturing images during the vehicle's movement. The target image differential signal refers to the initially encoded image signal, used for further processing; optionally, the target image differential signal can be a GMSL (Gigabit Multimedia Serial Link) or LVDS (Low-Voltage Differential Signaling) image signal. The data decoding module refers to the hardware component that decodes the image signal for efficient transmission.
[0030] For example, the camera module encodes the initial image signal received by the target vehicle during driving into a GMSL or LVDS image signal, and transmits the GMSL or LVDS image signal to the data decoding module via serial transmission.
[0031] In one alternative implementation, before the target image differential signal is obtained by first encoding the initial image signal received by the target vehicle during driving through the camera module, the data encoding module, data decoding module and camera module can be configured sequentially through the data receiving terminal via the GMSL or LVDS protocol's overall control information IIC (Inter-Integrated Circuit).
[0032] S120. The candidate protocol signal is obtained by first decoding the differential signal of the target image through the data decoding module, and then sent to the data encoding module through a high-speed serial or parallel interface.
[0033] Among them, the candidate protocol signal refers to the signal generated after the initial decoding, containing protocol or structural information about the image data; optionally, this protocol signal can be a MIPI CSI (Mobile Industry Processor Interface Camera Serial Interface) protocol signal. High-speed serial or parallel interfaces include high-speed serial interfaces and high-speed parallel interfaces; a high-speed serial interface refers to a high-speed data transmission interface that allows for fast and reliable data transmission between different modules; a high-speed parallel interface refers to transmitting multiple bits (data bits) simultaneously through multiple data lines to achieve high-speed data transmission. The data encoding module refers to the hardware component responsible for encoding the image signal for efficient transmission.
[0034] For example, the data receiving module performs initial decoding on the received GMSL or LVDS image signal to convert the received image signal into a MIPI CSI protocol signal, and then sends the decoded MIPI CSI protocol signal to the data encoding module.
[0035] S130. The candidate protocol signal is encoded twice by the data encoding module to obtain the target image differential signal, and the target image differential signal is sent to the data receiving module.
[0036] The data receiving module refers to the hardware component that receives, further processes, or displays the differential signal of the target image.
[0037] For example, the received MIPI CSI protocol signal is re-encoded by the data encoding module to convert the MIPI CSI protocol signal back into a GMSL or LVDS image signal, and the GMSL or LVDS image signal is sent to the data receiving module; the data receiving module receives the final GMSL or LVDS image signal.
[0038] In one optional embodiment, the camera data transmission system of this application provides a power supply scheme, including a first connection module, a second connection module, a first POC (Power over Coaxial) module, a second POC module, and a power supply module; the first connection module is connected to the camera module, the first POC module, and the data decoding module respectively; the second connection module is connected to the data receiving module, the second POC module, and the data encoding module respectively.
[0039] Specifically, the second connection module supplies power to the second POC module; the second POC module supplies power to the first POC module and the power module respectively; the first POC module supplies power to the camera module; and the power module supplies power to the data decoding module and the data encoding module respectively.

[0041] Specifically, the second connection module supplies power to the second POC module; the power connection module connects to the vehicle's onboard power supply and obtains power to supply the power module; the second POC module enables the power module; the power module supplies power to the first POC module; the first POC module supplies power to the camera module; and the power module supplies power to the data decoding module and the data encoding module respectively.
[0042] It should be noted that when the second POC module is not enabled, the power module is turned off, thereby saving power consumption.
[0043] Understandably, adding a power connection module can increase the product's adaptability and better compatibility with various car models.
[0044] This embodiment of the application uses a camera module to perform initial encoding on the initial image signal received by the target vehicle during its movement to obtain a target image differential signal, which is then sent to a data decoding module. The data decoding module performs initial decoding on the target image differential signal to obtain a candidate protocol signal, which is then sent to a data encoding module via a high-speed serial or parallel interface. The data encoding module performs secondary encoding on the candidate protocol signal to obtain the target image differential signal, which is then sent to a data receiving module. This technical solution, by introducing a data decoding module and a data encoding module during camera data transmission to convert and transmit the image differential signal, can effectively improve the transmission distance of camera image data.

[0046] Figure 2 This is a flowchart of a camera data transmission method according to Embodiment 2 of this application. Based on the technical solutions of the above embodiments, this embodiment refines the process of "encoding the initial image signal received by the target vehicle during its driving process using the camera module to obtain a target image differential signal" to "determining the initial signal type of the initial image signal received by the target vehicle during its driving process using the camera module; determining the enable signal type of the initial image signal using the camera module according to pre-configured encoding rules; wherein the enable signal types include multimedia serial link signals and low-voltage differential signals; converting the initial signal type of the initial signal into an enable signal type using the camera module to obtain the target image differential signal." It should be noted that for parts not detailed in this embodiment, please refer to the relevant descriptions in other embodiments. Figure 2 As shown, the method includes:
[0047] S210. Determine the initial signal type of the initial image signal received by the target vehicle during its driving process using the camera module.
[0048] The initial image signal refers to the raw image data received by the camera module during driving; these signals are usually the result of optical signals being converted into electrical signals by sensors. The initial signal type refers to the specific format or encoding method of the initial image signal, such as analog or digital signals; this type determines the signal processing and transmission method.
[0049] S220. The camera module determines the enable signal type of the initial image signal according to the pre-configured encoding rules; wherein, the enable signal type includes multimedia serial link signal and low voltage differential signal.
[0050] Encoding rules refer to the configuration data used by the camera module to encode image signals. Encodingable signal types refer to signal types that can be effectively processed and transmitted through specific encoding rules; common encodingable signal types include Multimedia Serial Link (GMSL) and Low Voltage Differential Signaling (LVDS), which are suitable for efficient data transmission. GMSL is a communication protocol used for high-speed data transmission, primarily applied in automotive electronic systems. LVDS is an electrical signal standard used for high-speed data transmission, reducing electromagnetic interference and signal attenuation through differential signaling.
[0051] Optionally, the camera data transmission system also includes a data processing module; the data processing module is connected to the camera module via a serial communication protocol; correspondingly, the encoding rules are sent to the camera module through the data processing module.
[0052] Specifically, the data processing module is configured sequentially via the IIC bus to include the data encoding module, the data decoding module, and the camera module.
[0053] Understandably, introducing a data processing module into the system, and configuring the data encoding module, data decoding module, and camera module through the data processing module, can effectively reduce the development difficulty and costs associated with control via the receiving terminal.
[0054] S230: The camera module converts the initial signal type of the initial image signal into an encodeable signal type to obtain the target image differential signal, and sends the target image differential signal to the data decoding module.
[0055] Among them, the target image differential signal refers to the converted image signal that conforms to the format of the coded signal type; after appropriate processing, these signals can be used for subsequent data decoding.
[0056] For example, the received image signal is encoded and converted into a GMSL or LVDS image signal by the camera module, and then the GMSL or LVDS image signal is sent to the data decoding module.
[0057] S240. The candidate protocol signal is obtained by first decoding the differential signal of the target image through the data decoding module, and then sent to the data encoding module through a high-speed serial or parallel interface.
[0058] Optionally, the data decoding module determines the convertible protocol signal type of the target image differential signal according to the pre-configured decoding rules; the data decoding module converts the signal type of the target image differential signal into the protocol signal type to obtain the candidate protocol signal.
[0059] Decoding rules refer to a set of predefined specifications or algorithms that guide the data decoding module in converting the input signal type into the target signal type. Decoding rules typically include information such as signal format, encoding method, and data structure. Protocol signal type refers to the signal type formatted according to a specific communication protocol (such as MIPI, LVDS, etc.), which enables the signal to be effectively transmitted between different devices; for example, the protocol signal type could be the MIPI CSI protocol.
[0060] Furthermore, the data processing module is connected to the data decoding module and the data encoding module via a serial communication protocol; correspondingly, the decoding rules are sent to the camera module through the data processing module.
[0061] S250. The candidate protocol signal is encoded twice by the data encoding module to obtain the target image differential signal, and the target image differential signal is sent to the data receiving module.
[0062] Optionally, the data encoding module determines the candidate signal type that can be encoded by the target image differential signal according to the encoding rules; the data encoding module converts the protocol signal type of the candidate protocol signal into the candidate signal type to obtain the target image differential signal.
[0063] Candidate signal types refer to possible signal formats or standards during the encoding process. These signal types can be encoded into target signals under specific conditions. These signal types can include multimedia serial link signals and low-voltage differential signals.
[0064] This application embodiment determines the initial signal type of the initial image signal received by the target vehicle during its operation using a camera module. The camera module then determines the encodeable signal type of the initial image signal according to pre-configured encoding rules. The encodeable signal types include multimedia serial link signals and low-voltage differential signals. The camera module converts the initial signal type into an encodeable signal type to obtain the target image differential signal, which is then sent to a data decoding module. The data decoding module performs an initial decoding of the target image differential signal to obtain a candidate protocol signal, which is then sent to a data encoding module via a high-speed serial or parallel interface. Finally, the data encoding module performs a secondary encoding of the candidate protocol signal to obtain the target image differential signal, which is then sent to a data receiving module. This technical solution, by introducing a data decoding module and a data encoding module during camera data transmission to convert and transmit the image differential signal, can effectively improve the transmission distance of camera image data.
