[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: obtain an initial image, convert the format of the initial image to obtain a target format image; encode the target format image to obtain a picture data packet; send the picture data packet to the domain controller through a preset interface adapter to complete the picture re-injection test, and the preset interface adapter has a preset hardware address.

[0052] In this embodiment, for the convenience of description, the following description is made by taking the internal actuator of the image recharge test system as the execution subject.

[0053] Since the existing image re-injection test system mostly relies on a dedicated hardware data transmission module, the cost is high and the parallel verification test of the domain controller cannot be implemented.

[0054] The present application provides a solution, which uses a software-simulated encoding component to encode images, and forwards image data in parallel through a preset interface adapter at Layer 2, thereby improving the testing efficiency of the domain controller.

[0055] It can be seen from the above embodiments that the present application adopts a software-simulated encoding component to encode images and forwards image data in parallel through a preset interface adapter at the second layer, thereby solving the problem that the current image re-injection test system mostly relies on dedicated hardware data transmission modules, is costly and cannot realize parallel verification testing of domain controllers, thereby improving the testing efficiency of domain controllers.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes the internal actuator of the image recharge test system as an example to illustrate this embodiment and the following embodiments.

[0057] Based on this, the present application embodiment provides a method for testing image re-entry. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the image re-injection testing method of the present application.

[0058] In this embodiment, the image replay test method includes steps S10 to S30:

[0059] Step S10, obtaining an initial picture, and performing format conversion on the initial picture to obtain a target format picture.

[0060] It should be noted that the initial image is a single-frame image in JPEG format captured by the camera during the actual vehicle verification of the autonomous driving or assisted driving software domain controller, and the target format image is a RAW format image.

[0061] In addition, it should be noted that JPEG (Joint Photographic Experts Group) is a widely used image file format, mainly used to store static color or black and white pictures. The RAW format is an image file format that saves the unprocessed image data captured by the camera sensor, providing more complete information, allowing greater flexibility and higher image quality in post-processing. A single-frame picture refers to a static image and does not contain multiple frames in any animation or video sequence.

[0062] Step S20, encoding the target format picture to obtain a picture data packet.

[0063] The GMSL2 encoding component is constructed through software simulation, and the RAW format images obtained after format conversion are encoded into images that meet the GMSL2 protocol and packaged into image data packets.

[0064] It should be noted that GMSL2 (Gigabit Multimedia Serial Link 2) is a high-speed serial interface protocol, mainly used in video applications in the automotive industry, such as entertainment systems and advanced driver assistance systems (ADAS). GMSL2 is an upgraded version of GMSL1, providing higher data transmission rates and improved performance.

[0065] Step S30, sending the picture data packet to the domain controller through a preset interface adapter to complete the picture re-injection test, wherein the preset interface adapter has a preset hardware address.

[0066] It should be noted that the preset interface adapter is the FAKRA interface adapter. The domain controller (DC) is a server in a computer network system. It is responsible for managing and maintaining user accounts, passwords, security policies, computer accounts and other security-related information in the network. The domain controller in the field of autonomous driving testing is the core component for realizing autonomous driving functions. It is responsible for processing data from various vehicle sensors, executing autonomous driving algorithms, and controlling the driving of the vehicle. The preset hardware address is the MAC address.

[0067] In addition, it should be noted that the FAKRA interface adapter is a radio frequency (RF) connector used in automotive electronic systems. It is mainly used to transmit high-speed data and video signals. It can operate stably in the harsh environment inside the vehicle, can withstand a wide temperature range and resist electromagnetic interference. The MAC address is called the Media Access Control address (Media Access Control address). It is a unique identifier for each device in the network. It is usually burned into the hardware of network devices, such as network cards, routers, switches, smartphones, tablets, etc., and is used to communicate at the data link layer. The FAKRA interface adapter with a MAC address can connect a 10 Gigabit Ethernet switch between a server and multiple FAKRA interface adapters.

[0068] Reference Figure 2 , Figure 2 A data flow module schematic diagram of an image re-injection test method is provided, including: a mobile hard disk, a server, a FAKRA interface adapter, and an autonomous driving domain controller. The server includes a DMA controller and a GMSL2 encoding component.

[0069] This embodiment provides an image re-injection test method, which uses a software-simulated encoding component to encode images, and forwards image data in parallel through a preset interface adapter at Layer 2. This solves the problem that the current image re-injection test system mostly relies on dedicated hardware data transmission modules, is costly and cannot implement parallel verification testing of domain controllers, thereby improving the testing efficiency of domain controllers.

[0070] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20 includes steps S21 to S23:

[0071] Step S21, obtaining the timestamp of the target format picture.

[0072] It should be noted that a timestamp is an integer value used to represent a specific point in time. It usually takes a specific point in time as the starting point and calculates the number of seconds or milliseconds from the starting point to the specific point in time. The timestamp in an image file refers to the date and time information related to the creation, modification or processing of the image.

[0073] Step S22: Encode the target format picture into a target picture according to the timestamp.

[0074] According to the timestamp of the acquired image, the target format image is encoded in sequence into a target image that meets the GMSL2 protocol through the GMSL2 encoding component.

[0075] It should be noted that meeting the GMSL2 protocol refers to whether the image can be transmitted through a system that meets the GMSL2 protocol.

[0076] In a feasible implementation, step S22 may include steps S201 to S205:

[0077] Step S201, arranging the target format pictures in sequence according to the timestamps to obtain a coding sequence.

[0078] Arrange the target format pictures in order according to the timestamps, and the pictures with earlier creation times have earlier encoding orders, and so on, to obtain the encoding order of the pictures.

[0079] Step S202: Encode the target format picture according to the encoding order to obtain an encoded picture.

[0080] According to the encoding order of the pictures, the pictures are encoded in sequence through the GMSL2 encoding component, so that the pictures can be transmitted through a system that meets the GMSL2 protocol. The encoded pictures are called encoded pictures.

[0081] Step S203, verifying whether the encoded image meets the preset protocol and obtaining a verification result.

[0082] Verify whether the encoded image meets the preset protocol, that is, verify whether the image can be transmitted through the GMSL2 system. It is necessary to ensure that the image data format, data rate, and system configuration meet the requirements of the GMSL2 protocol. The image data format needs to be compatible with the GMSL2 system, that is, the image needs to be in an uncompressed image file format, the image transmission data volume is within the bandwidth range of the GMSL2 link, and the system configuration needs to be a GMSL2 link.

[0083] When any of the image data format, data rate, and system configuration does not meet the requirements of the GMSL2 protocol, the verification result is that the encoded image does not meet the preset protocol. When the image data format, data rate, and system configuration all meet the requirements of the GMSL2 protocol, the verification result is that the encoded image meets the preset protocol.

[0084] Step S204, when the verification result is that the encoded picture does not satisfy the preset protocol, return to the step of encoding the target format picture according to the encoding order to obtain the encoded picture.

[0085] When the verification result is that the encoded image does not meet the preset protocol, the process of encoding the image is returned, and the image is re-encoded and verified.

[0086] Step S205: When the verification result is that the encoded picture satisfies the preset protocol, the encoded picture is used as a target picture.

[0087] When the verification result is that the encoded image meets the preset protocol, the image verification process is completed and the encoded image is used as the target image.

[0088] The image is encoded and verified through the GMSL2 encoding component simulated by software to obtain an image that meets the GMSL2 protocol, reducing the complexity of image data re-injection.

[0089] Step S23, packing the target image into an image data packet.

[0090] It should be noted that packaging the images into data packets means dividing the binary data of the image files into small blocks and encapsulating them.

[0091] This embodiment provides a method for testing image re-injection, which obtains the timestamp of the target format image; encodes the target format image into a target image according to the timestamp; and packages the target image into an image data packet, thereby reducing the complexity and cost of image data re-injection.

[0092] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 , step S30 includes steps S31-S32:

[0093] Step S31, sending an Ethernet line signal containing the image data packet to a preset interface adapter via an Ethernet line, so that the preset interface adapter converts the Ethernet line signal into a coaxial cable signal.

[0094] It should be noted that Ethernet cable, also known as Ethernet cable, is a physical transmission medium used to connect Ethernet devices (such as computers, printers, switches, routers, etc.). It follows the IEEE 802.3 standard and is used to transmit data. Ethernet cable signal refers to the electrical signal transmitted through the Ethernet cable, which is usually a digital signal and follows specific encoding rules. Coaxial cable signal refers to the electrical signal transmitted through the coaxial cable.

[0095] The FAKRA interface adapter can convert electrical signals transmitted through Ethernet cables into electrical signals transmitted through coaxial cables. During the signal conversion process, the FAKRA adapter first receives electrical signals from the Ethernet cable through its input port. The circuit inside the adapter processes these signals to ensure that they can adapt to the transmission characteristics of the coaxial cable. The processing process includes decoding, re-encoding or re-timing of the signal, and then converting the processed signal into a format suitable for transmission on the coaxial cable. The converted signal is output through the FAKRA interface of the adapter for transmission on the coaxial cable. The output port of the FAKRA interface adapter is a standard FAKRA interface, which means it can be seamlessly connected with other devices that comply with the FAKRA standard.

[0096] In a feasible implementation, step S31 may include steps S301 to S304:

[0097] Step S301, obtaining a preset address of a preset interface adapter.

[0098] Get the MAC address of the FAKRA interface adapter, which is used by the server to send image data packets to the FAKRA interface adapter through the Ethernet cable.

[0099] Step S302, generating an Ethernet line signal including the image data packet.

[0100] Generate an electrical signal that can be transmitted through the Ethernet line, convert the picture data packet into binary form, and use a specific encoding scheme (such as Manchester encoding, non-return-to-zero encoding, differential encoding, etc.) to map the binary data to the electrical signal.

[0101] Step S303: encapsulate the Ethernet line signal in an Ethernet frame based on the preset address.

[0102] It should be noted that the Ethernet frame is the encapsulation unit of the data link layer, which is used to transmit data on the Ethernet. It includes a series of fields, each of which has a specific function. The structure of the Ethernet frame includes the frame start flag (Preamble), the start frame delimiter (SFD), the destination MAC address, the source MAC address, the type / length field, the data load (Payload) and the frame check sequence (FCS).

[0103] The data link layer of the server encapsulates the Ethernet line signal in an Ethernet frame, wherein based on the MAC address of the FAKRA interface adapter, the server can fill in the MAC address of the FAKRA interface adapter in the destination MAC address field of the frame to ensure the uniqueness of the signal transmission address.

[0104] Step S304: sending the Ethernet frame to the preset interface adapter via the Ethernet cable, so that the preset interface adapter converts the Ethernet frame into a coaxial cable signal.

[0105] The FAKRA interface adapter with a MAC address can be connected to a 10G switch to forward the data packets output by the GMSL2 encoding component at Layer 2. The 10G switch receives the Ethernet frame containing the image data packet sent by the server, and sends the Ethernet frame to the corresponding FAKRA interface adapter through the Ethernet cable, so that the FAKRA interface adapter converts the electrical signal transmitted through the Ethernet cable into an electrical signal transmitted through the coaxial cable.

[0106] It should be noted that Layer 2 forwarding refers to the packet forwarding process performed at the data link layer of the network (i.e., the second layer of the OSI model). This layer mainly handles the transmission of frames, rather than the packets processed by the network layer (the third layer of the OSI model). Layer 2 forwarding is usually performed by a switch, which uses the destination MAC address in the received frame to decide how to forward the frame to the corresponding destination. The 10 Gigabit switch has multiple ports, each of which can be connected to a FAKRA interface adapter, allowing data to be efficiently converted and transmitted between Ethernet and FAKRA interfaces, while providing network management and optimization functions.

[0107] Reference Figure 5 , Figure 5 A schematic diagram of a layer 2 data forwarding module of an image re-injection test method is provided, including: a mobile hard disk, a server, a 10 Gigabit switch, a FAKRA interface adapter, and an autonomous driving domain controller. The server includes a DMA controller and a GMSL2 encoding component.

[0108] Data is transmitted through a FAKRA interface adapter with a MAC address to implement Layer 2 forwarding and re-injection of image data packets.

[0109] Step S32, sending the coaxial cable signal to the domain controller corresponding to the preset interface adapter via a coaxial cable to complete the image replay test, and different preset interface adapters correspond to different domain controllers.

[0110] It should be noted that coaxial cable is an electrical transmission line, which is mainly used for the transmission of radio frequency signals. The FAKRA interface is usually used to connect a single transmitter (such as a camera) and a single receiver (such as a domain controller). Different FAKRA interface adapters correspond to different connected domain controllers.

[0111] The Ethernet line signal is converted into a coaxial cable signal through the FAKRA interface adapter, and then sent to the corresponding domain controller via the coaxial cable, so that the domain controller can complete the image re-injection test. Different FAKRA interface adapters correspond to different domain controllers, so multiple domain controllers can obtain re-injection data in parallel.

[0112] The present embodiment provides a method for testing image re-injection, which includes sending an Ethernet line signal containing the image data packet to a preset interface adapter via an Ethernet cable, so that the preset interface adapter converts the Ethernet line signal into a coaxial cable signal; sending the coaxial cable signal to a domain controller corresponding to the preset interface adapter via a coaxial cable to complete the image re-injection test, where different preset interface adapters correspond to different domain controllers, thereby realizing Layer 2 forwarding of re-injected image data packets and multiple domain controllers obtaining re-injected data in parallel, thereby improving the testing efficiency of the domain controller.

[0113] Based on the first embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 6 , step S10 includes steps S11 to S12:

[0114] Step S11, obtaining the initial image in the mobile hard disk.

[0115] It should be noted that a mobile hard disk is a portable external storage device that uses hard disk drive (HDD) or solid-state drive (SSD) technology to store data and is connected to a computer or other devices via USB or other interfaces (such as Thunderbolt, eSATA, etc.).

[0116] The vehicle collects single-frame images in JPEG format through the camera and stores them in a mobile hard disk. The mobile hard disk is mounted on the server so that the server can read the data in the mobile hard disk.

[0117] Step S12, reading the initial image into the image format conversion component through a preset controller, so that the image format conversion component converts the image format of the initial image into a preset image format to obtain a target format image.

[0118] It should be noted that the preset controller is a DMA controller. The DMA (Direct Memory Access) controller is a hardware device that allows certain hardware subsystems to directly access the system memory without going through the central processing unit (CPU). Its main function is to accelerate data transmission, reduce the burden on the CPU, and improve the overall performance of the system. The image format conversion component refers to a software or hardware tool that can convert an image from one file format to another. The conversion process usually reads the data of the original image file, decodes it and re-encodes it into a new format. The preset image format is the RAW format.

[0119] This embodiment provides a method for image replay testing, which obtains an initial image in a mobile hard disk; reads the initial image to an image format conversion component through a preset controller, so that the image format conversion component converts the image format of the initial image into a preset image format, and obtains a target format image, thereby providing a format basis for subsequent encoding of the image.

[0120] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the image re-injection test method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0121] This application also provides a picture re-injection test device, please refer to Figure 7 , the device comprises:

[0122] The format conversion module 10 is used to obtain an initial image, and perform format conversion on the initial image to obtain a target format image.

[0123] The picture encoding module 20 is used to encode the target format picture to obtain a picture data packet.

[0124] The data transmission module 30 is used to send the image data packet to the domain controller through a preset interface adapter to complete the image re-injection test, and the preset interface adapter has a preset hardware address.

[0125] In one embodiment, the picture encoding module 20 is further used to obtain the timestamp of the target format picture; encode the target format picture into a target picture according to the timestamp; and pack the target picture into a picture data packet.

[0126] In one embodiment, the picture encoding module 20 is also used to arrange the target format pictures in sequence according to the timestamps to obtain a coding order; encode the target format pictures according to the coding order to obtain a coded picture; verify whether the coded picture satisfies a preset protocol to obtain a verification result; when the verification result is that the coded picture does not satisfy the preset protocol, return to the step of encoding the target format picture according to the coding order to obtain a coded picture; when the verification result is that the coded picture satisfies the preset protocol, use the coded picture as the target picture.

[0127] In one embodiment, the data transmission module 30 is also used to send an Ethernet line signal containing the image data packet to a preset interface adapter via an Ethernet cable, so that the preset interface adapter converts the Ethernet line signal into a coaxial cable signal; and send the coaxial cable signal to a domain controller corresponding to the preset interface adapter via a coaxial cable to complete the image re-injection test, and different preset interface adapters correspond to different domain controllers.
