[0044] First, the application scenarios to which the present application is applicable are introduced. The embodiments provided in the present application are applicable to the field of data processing technology.

[0045] At present, the communication medium supports coaxial cable and shielded twisted pair. When using 50Ω coaxial cable or 100Ω shielded twisted pair, the transmission distance of the communication medium can reach 15 meters. The communication protocol based on the GMSL architecture can achieve a maximum single-channel rate of 6Gbps, which is widely used in the field of autonomous driving.

[0046] Due to the different types of GMSL car displays and the incompatibility of different types of GMSL car displays, the video stream data between different types of GMSL car displays cannot be displayed and compatible with each other, and if the GMSL car display and the GMSL serial data are incorrectly matched, they cannot be displayed normally, which leads to the low practicality of the data display.

[0047] Based on this, the embodiments of the present application provide a data conversion method, system and device that are adapted to different vehicle machine displays. The embodiments provided by the present application solve the problem in the autonomous driving domain that the target video stream data to be detected can only be displayed on a matching target vehicle machine display and cannot be displayed on an unmatched target vehicle machine display. That is, it solves the synchronous display of the target video to be detected on different types of target vehicle machine displays, so that the data display between different types of target vehicle machine displays is compatible.

[0048] See also Figure 1 , Figure 1 A flowchart of a data conversion method adapted to different vehicle displays provided in an embodiment of the present application, such as Figure 1 As shown, the data conversion method adapted to different vehicle machine displays includes the following steps:

[0049] S101. Deserialize the target video stream data to be detected according to a preset deserializer to determine at least one parallel deserialized video stream data corresponding to the target video stream data.

[0050] In this step, when it is necessary to display a panoramic image around the target vehicle, first, the target video stream data to be detected is collected through multiple cameras on the vehicle body, and a panoramic image is generated by splicing to provide a 360-degree all-round viewing angle for detecting and displaying obstacles and other vehicles around the vehicle. After receiving the display instruction from the main control MCU, the collected target video stream data to be detected is deserialized according to the preset deserializer to determine at least one parallel deserialized video stream data corresponding to the target video stream data. Here, it is assumed that there are two parallel deserialized video stream data in the embodiment provided in the present application.

[0051] See also Figure 2 , Figure 2 A block diagram corresponding to the main control MCU in a data conversion method adapted to different vehicle machine displays provided in an embodiment of the present application, such as Figure 2As shown, the main control MCU mainly outputs signals through the data bus.

[0052] See also Figure 3 , Figure 3 A block diagram corresponding to a preset deserializer in a data conversion method adapted to different vehicle machine displays provided in an embodiment of the present application, such as Figure 3 As shown, the preset deserializer is connected to the main control MCU via a data bus, and the preset deserializer receives the target video stream data to be detected. Here, it is assumed that the model of the preset deserializer in the embodiment provided by the present application can be specifically but not limited to: MAX9296A.

[0053] It can be understood that in the embodiment provided by the present application, after the preset deserializer receives the target video stream data to be detected sent by the external autonomous driving domain controller through the coaxial cable COAX, the target video stream data to be detected is deserialized, and the target video stream data to be detected is deserialized into two-way duplicated CSI-2 camera parallel deserialized video stream data.

[0054] It is assumed that the target video stream data to be detected in the embodiment provided in the present application can be GMSL1 plus string data or GMSL2 plus string data.

[0055] Among the above, Gigabit Multimedia Serial Links (GMSL) is a high-speed serial interface suitable for the transmission of audio, video and control signals; the interface standard (camera serial interface 2, CSI-2) is an interface standard specified by the Camera Working Group under the MIPI Alliance, which is mainly used to define the interface between camera peripherals and host controllers, and aims to determine the standards for cameras and host controllers in mobile applications.

[0056] S102 . For any target vehicle display, based on the target type of the target vehicle display, determine whether it is necessary to perform signal conversion on any parallel deserialized video stream data.

[0057] In this step, after the target video stream data to be detected is deserialized into two parallel deserialized video stream data of the replicated CSI-2 camera through the preset deserializer, it is necessary to determine whether the parallel deserialized video stream data can match the type of the target vehicle display. Therefore, at this time, it is necessary to determine whether any of the above-mentioned parallel deserialized video stream data needs to be converted into signals based on the target type of the target vehicle display.

[0058] It can be understood that, it is assumed that the target types of the target vehicle display in the embodiment provided by the present application include a type of standard target vehicle display GMSL2 commonly seen on the market, and a type of old version of the target vehicle display GMSL1 before the update.

[0059] S103: If the deserialized video stream data does not need to be converted into a signal, based on the deserialized video stream data and a second preset serializer, the deserialized video stream data is converted into second serialized video stream data compatible with the target vehicle display.

[0060] In this step, after determining that the deserialized video stream data does not need to be converted into signals, the deserialized video stream data of this path is connected to the second preset serializer through the MIPI interface, and the deserialized video data is converted into second serialized video stream data compatible with the target vehicle display, and then the second serialized video stream data is displayed on the corresponding target vehicle display GMSL2 through a coaxial cable, thereby realizing the display of the surround panoramic image video.

[0061] It can be understood that, it is assumed that the second string video stream data in the embodiments provided in the present application can be specifically but not limited to the GMSL2 string video stream.

[0062] S104: If the deserialized video stream data needs to be converted into a signal, based on the deserialized video data and a preset signal converter, the deserialized video data is converted into a first serialized video stream data compatible with the target vehicle display.

[0063] In this step, after determining that the deserialized video stream data needs to be converted into signals, the embodiment provided by the present application connects the deserialized video stream data to a preset signal converter through a MIPI interface, and then performs corresponding signal conversion on the deserialized video stream data according to the provisions of the preset signal converter, and after the conversion, passes through a first preset serializer to determine the first serialized video stream data that is compatible with the target vehicle display.

[0064] It can be understood that, it is assumed that the first added string video stream data in the embodiment provided in the present application can be specifically but not limited to the first added string video stream data GMSL1.

[0065] The data conversion method adapted to different vehicle-mounted display devices provided in the embodiment of the present application, compared with the prior art, is a method for converting data adapted to different vehicle-mounted display devices by deserializing the target video stream data to be detected according to a preset deserializer, determining at least one parallel deserialized video stream data corresponding to the target video stream data, and for any target vehicle-mounted display device, determining whether it is necessary to perform signal conversion on any parallel deserialized video stream data based on the target type of the target vehicle-mounted display device, and when it is not necessary to perform signal conversion on the deserialized video stream data, converting the deserialized video data into a signal adapted to the target vehicle-mounted display device based on the deserialized video stream data and the second preset deserializer. The second serial video stream data matched with the deserialized video stream data is obtained, and when the deserialized video stream data needs to be converted into a signal, the deserialized video data is converted into the first serial video stream data matched with the target vehicle display based on the deserialized video data and the preset signal converter, thereby solving the problem that the target video stream data to be detected in the autonomous driving domain can only be displayed on the matched target vehicle display but cannot be displayed on the unmatched target vehicle display, that is, the synchronous display of the target video to be detected on different types of target vehicle displays is solved, and the compatibility between different types of target vehicle displays is achieved, thereby improving the practicability of the target vehicle display.

[0066] In one embodiment, the target type includes a first type and a second type, and step S102 includes the following sub-steps:

[0067] Sub-step 1021 : for any target vehicle display, if the target vehicle display is of the second type, it is not necessary to perform signal conversion on any parallel deserialized video stream data.

[0068] In this step, after determining that the target vehicle display on the target vehicle is of the second type, ie, the common standard target vehicle display GMSL2, it is determined that the parallel deserialized video stream data needs to be signal converted.

[0069] Sub-step 1022: If the target vehicle display is of the first type, it is necessary to perform signal conversion on any parallel deserialized video stream data, wherein the target vehicle display of the second type is incompatible with the target vehicle display of the second type.

[0070] In this step, if the target vehicle display is of the first type, that is, a relatively old version of the target vehicle display GMSL1 before the market update, it is necessary to perform signal conversion on the deserialized video stream data so that the target video stream data to be detected can be matched and compatible with the target vehicle display GMSL1.

[0071] Among them, it is assumed that the 2 parallel deserialized video stream data in the embodiment provided in this application include 1 GMSL1 deserialized video stream data and 1 GMSL2 deserialized video stream data, and the target type of the target vehicle display includes a GMSL1 vehicle display and a GMSL2 vehicle display.

[0072] In one embodiment, if the deserialized video stream data does not need to be converted into a signal, based on the deserialized video stream data and the second preset serializer, the deserialized video data is converted into second serialized video stream data compatible with the target vehicle display, including:

[0073] If the deserialized video stream data does not need to be converted into a signal, the deserialized video stream data is serialized according to a second preset serializer to convert the deserialized video data into second serialized video stream data compatible with a second type of target vehicle display.

[0074] In the above, if there is no need to perform signal conversion on the deserialized video stream data, the deserialized video stream data is connected to the second preset serializer through the MIPI interface to generate second serialized video stream data, and then the second serialized video stream data is connected to the GMSL2 target vehicle display through a coaxial cable to display the surround panoramic image video.

[0075] See also Figure 4 , Figure 4 A block diagram corresponding to the second preset serializer in a data conversion method adapted to different vehicle machine displays provided in an embodiment of the present application, such as Figure 4 As shown, the model of the second preset serializer can be specifically but not limited to MAX95717.

[0076] In one embodiment, see Figure 5 , Figure 5 A block diagram corresponding to a preset signal converter in a data conversion method adapted to different vehicle machine displays provided in an embodiment of the present application, step S104 includes the following sub-steps:

[0077] Sub-step 1041: If the deserialized video stream data needs to be converted into a signal, the deserialized video data is converted into a low voltage differential signal according to a preset signal converter to determine the low voltage differential video stream data corresponding to the deserialized video stream data.

[0078] In this step, when the deserialized video stream data needs to be converted into a signal, the deserialized video data is connected to a preset signal converter through a MIPI interface, and low-voltage differential signal conversion is performed according to the preset signal converter to determine the low-voltage differential video stream data corresponding to the deserialized video stream data.

[0079] It is assumed that the preset signal converter in the embodiment provided in the present application is specifically used to convert the data stream into an LVDS (Low-Voltage Differential Signaling) low-voltage differential signal data stream.

[0080] Among the above, Figure 5 As shown, the preset signal converter specifically outputs an LVDS low voltage differential signal data stream.

[0081] Sub-step 1042: according to the first preset serializer, the low voltage differential video stream data is serialized, and the deserialized video data is converted into first serialized video stream data compatible with the first type of target vehicle display.

[0082] Please refer to Figure 6 , Figure 6 A block diagram corresponding to a first preset serializer in a data conversion method adapted to different vehicle machine displays provided in an embodiment of the present application, such as Figure 6 As shown, the model of the first preset serializer can be specifically but not limited to MAX9249.

[0083] In this step, the low voltage differential video stream data is connected to the first preset serializer GMSL, and the data stream is converted into the first serialized video stream data compatible with the first type of target vehicle display.

[0084] In one embodiment, after the low voltage differential video stream data is serialized according to the first preset serializer and the deserialized video data is converted into the first serialized video stream data adapted to the first type of target vehicle display, the data conversion method adapted to different vehicle displays also includes:

[0085] The first added video stream data is displayed on a first type of target vehicle display, and the second added video stream data is displayed on a second type of target vehicle display, wherein the first type of target vehicle display and the second type of target vehicle display are both installed on the target vehicle.

[0086] In the above, the embodiment provided by the present application can display the target video stream data on the first type of target vehicle display and the second type of target vehicle display, that is, it solves the problem of displaying the same target video stream data to be detected on the GMSL1 and GMSL2 target vehicle displays at the same time.

[0087] The data conversion method adapted to different vehicle-mounted display devices provided in the embodiment of the present application, compared with the prior art, is as follows: the embodiment provided by the present application performs deserialization on the target video stream data to be detected according to a preset deserializer, determines at least one parallel deserialized video stream data corresponding to the target video stream data, and for any target vehicle-mounted display device, determines whether it is necessary to perform signal conversion on any parallel deserialized video stream data based on the target type of the target vehicle-mounted display device; when it is not necessary to perform signal conversion on the deserialized video stream data, converts the deserialized video data into second serialized video stream data adapted to the target vehicle-mounted display based on the deserialized video stream data and a second preset serializer; and when it is necessary to perform signal conversion on the deserialized video stream data, determines whether it is necessary to perform signal conversion on the deserialized video stream data based on the deserialized video stream data and the second preset serializer; The deserialized video data and the preset signal converter are used to convert the deserialized video data into the first serial video stream data compatible with the target vehicle display, which solves the problem that the target video stream data to be detected can only be displayed on the matching target vehicle display but cannot be displayed on the unmatched target vehicle display in the autonomous driving domain, that is, the synchronous display of the target video to be detected on different types of target vehicle displays is solved, and the compatibility between different types of target vehicle displays is achieved, thereby improving the practicality of the target vehicle display. At the same time, it can realize the synchronous display of the same target video stream data to be detected on the GMSL1 and GMSL2 target vehicle displays, which greatly improves the compatibility of the target vehicle display while reducing the display and development costs.
