Description

Multi-mode driving method, device, vehicle and storage medium of camera

[0001] The present application claims priority to the Chinese patent application No. 202410838160.7, filed on June 26, 2024, to the Chinese Patent Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of cameras, for example to a multi-mode driving method, device, vehicle and storage medium of camera. BACKGROUND

[0003] With the rapid development of the automotive industry, software-defined vehicles are gradually becoming a reality. The software control of intelligent vehicles is developing towards full-stack and completeness. In the field of intelligent cockpit domain controllers, the demand for vehicle-mounted cameras is growing to support diversified and platformized intelligent functions.

[0004] Vehicle-mounted cameras are common functional devices for domain controllers. Conventional vehicle-mounted cameras include Around View Monitor (AVM) cameras, Rear View Camera (RVC), Driver Monitoring System (DMS) cameras, Occupant Monitoring System (OMS) cameras, Time of Flight (TOF) cameras, and Automatic Parking Assistant (APA) cameras, etc. Vehicle-mounted cameras have multiple mode combinations. For example, a vehicle of A car type is equipped with AVM, DMS and OMS cameras, and a vehicle of B car type is equipped with RVC, DMS and TOF cameras. Different vehicle models have diversified multi-mode driving needs of vehicle-mounted cameras.

[0005] However, the conventional driving mode of vehicle-mounted cameras has a single driving method. When multiple vehicle-mounted cameras use the same type of deserializer chip, due to factors such as serializer type, resolution communication protocol, frame rate, synchronization signal, data format and lighting configuration, even if the deserializer chip is the same, different driving methods are still needed to achieve the driving of the camera, which will cause high redundancy of driving and waste of resources of the operating system.

[0027] Embodiment One

[0028] FIG. 1 is a flowchart of a multi-mode driving method of a camera according to an embodiment of the present application. The embodiment can be applied to driving cameras of different modes.

[0029] As shown in FIG. 1, the multi-mode driving method of the camera according to the embodiment of the present application includes the following steps.

[0030] In S101, vehicle model information of a current vehicle is determined, and a target camera configuration file is determined from a camera mode configuration pool according to the vehicle model information. The target camera configuration file includes driving entry information and camera function information corresponding to a camera in the current vehicle.

[0031] In the embodiment, the vehicle model information of the vehicle can be determined by using a key KEY value as key information when facing different camera modes of different vehicle models. A camera mode configuration pool can be preconfigured, and the configuration pool can include a plurality of camera configuration files. The vehicle model and the camera configuration file have a corresponding relationship, and the camera configuration file corresponding to different vehicle models is different. According to the vehicle model information, a target camera configuration file matching the vehicle model of the current vehicle can be selected from the camera mode configuration pool. The driving entry information can be a deserializer chip name, and the camera function information can be camera mode information. The modes of the vehicle-mounted camera include AVM, RVC, DMS, OMS, TOF, APA, and the like. The camera function can be understood as the function corresponding to the mode of the camera.

[0032] In S102, a target driving function is determined from a driving program package by using the target camera configuration file. The driving program package includes driving functions of cameras with different functions.

[0033] In the embodiment, a plurality of camera driving programs of different modes can be packaged to obtain a driving program package. The driving programs of different camera modes are usually different. The target driving function can be determined from the driving program package by using the target camera configuration file. For example, the driving program package is called by using the driving entry information, and then the target driving function matching the camera function information is determined from the driving program package.

[0034] In S103, the camera configured in the current vehicle is driven by using the target driving function.

[0035] In the embodiment, the camera configured in the current vehicle can be driven by using the target driving function.

[0036] The multi-mode driving method of the camera provided by the embodiment of the application determines the vehicle model information of the current vehicle, and determines a target camera configuration file from a camera mode configuration pool according to the vehicle model information, wherein the target camera configuration file comprises driving entry information and camera function information corresponding to the camera in the current vehicle, a target driving function is determined from a driving program package by using the target camera configuration file, wherein the driving program package comprises driving functions of cameras with different functions, and the camera configured in the current vehicle is driven by using the target driving function. According to the embodiment of the application, the target camera configuration file comprising camera configuration information is accurately determined according to the vehicle model, and the driving function matched with the mode of the camera in the vehicle is quickly determined from the packaged driving program by using the configuration file, the driving function is used to drive the camera with different modes, the multi-mode driving of the vehicle camera system is realized, the system redundancy is reduced, the driving module of the operating system is simplified, strong support is provided for the intelligent cockpit domain controller, the full-stack and complete control of the intelligent automobile software is promoted, and the development needs of the future automobile industry are met.

[0037] In some embodiments, the way of determining the vehicle model information of the current vehicle comprises: determining the vehicle model information of the current vehicle from the product end-of-life configuration memory of the current vehicle by using the unique part number of the current vehicle.

[0038] Specifically, the product end-of-life configuration (End-of-life Config, Eolcfg) system in the vehicle can open a piece of memory in the system, and the memory is set with specific arrangement rules. The IC number (i.e., unique part number) of the vehicle is stored in the memory of the Eolcfg. For example, 0 to 128 bytes store the unique part number information of the vehicle, the next 128 bytes store the instrument panel information, and so on. When the IC number needs to be accessed, the information in the corresponding position can be accessed based on the memory rule table of the Eolcfg, that is, the access to the IC number can be realized. After the IC number is parsed, the vehicle model information can be determined.

[0039] In some embodiments, the driving of the camera configured in the current vehicle by using the target driving function comprises: calling a target header file by using the target driving function to realize the driving of the camera configured in the current vehicle, wherein the target header file is determined according to the vehicle model information.

[0040] Specifically, the configuration difference information of the serializer / deserializer (SerDes) is usually stored in the form of different.h files (header files). The header file corresponding to the current vehicle can be determined by using the vehicle model information, the target driver function is called by using the header file, and the content corresponding to the header file is accessed in the camera driver standardization program, so that the driving of the camera, the camera data stream transmission, and the camera format setting can be realized.

[0041] Embodiment Two

[0042] FIG. 2 is a flowchart of a multi-mode driving method of a camera according to an embodiment of the present application. The technical solution of the embodiment is further optimized on the basis of the above technical solutions, and a specific way of driving multiple cameras of different modes is given.

[0043] In some embodiments, before the determination of the vehicle model information of the current vehicle, the method further includes: for each vehicle model, writing the driving entry information, the camera function configuration information, the camera configuration information, and the general-purpose input / output port (GPIO) information of the camera corresponding to the configuration of the vehicle of the current vehicle model into an initial extensible markup language (XML) file to obtain a candidate XML file; generating a camera mode configuration pool by using the candidate XML file; and determining a target camera configuration file from the camera mode configuration pool according to the vehicle model information, wherein the target camera configuration file further includes the camera configuration information and the GPIO information of the camera in the current vehicle. In this way, the camera mode configuration pool of the XML file is generated by using the driving entry information, the camera function configuration information, the camera configuration information, and the GPIO information, which simplifies the complexity of the driving of the vehicle-mounted camera and reduces the maintenance difficulty and cost of the system. If a new demand arises, for example, a new vehicle model is added on the basis of the same platform, the content to be maintained and updated is greatly reduced, and only the XML file and the current driver package need to be updated, without the need to rebuild a set of driving method.

[0044] In some embodiments, the determination of the target driver function from the driver package by using the target camera configuration file includes: determining the driving entry of a main driver in the driver package by using the driving entry information in the target camera configuration file; and determining the target driver function from the driver package by using the driving entry and the camera function information. In this way, the driving function of the camera of different modes can be quickly determined.

[0045] In some embodiments, the driving the camera configured in the current vehicle by using the target driver includes: driving the camera configured in the current vehicle by using the target driver, the camera configuration information, and the GPIO information. In this way, the target driver, the camera configuration information, and the GPIO information can be used for each chip in various scenarios such as cross-platform, cross-vehicle factory, and cross-vehicle model, and the driving of various modes of cameras is realized.

[0046] As shown in FIG. 2, the multi-mode driving method of the camera provided in Embodiment Two of the present application specifically includes the following steps:

[0047] S201, for each vehicle of each vehicle model, write the driving entry information corresponding to the configured camera of the vehicle of the current vehicle model, the camera function configuration information, the camera configuration information, and the general-purpose input-output port (GPIO) information into an initial extensible markup language (XML) file to obtain an alternative XML file.

[0048] Specifically, the alternative XML file contains the driving entry information, the camera function configuration information, the camera configuration information, and the GPIO information. Each vehicle model corresponds to an alternative XML file. The extensible markup language is a markup language for storing data, which allows users to customize tags, so that the data structure can be defined more flexibly.

[0049] In some embodiments, the driving entry information includes deserializer chip information, the camera function configuration information includes a camera mode name, the camera configuration information includes a channel, a device address, a frame rate, a format, and a resolution, and the GPIO information includes GPIO information of a hardware platform of the current vehicle.

[0050] Specifically, the chip name can be used as a unique driver entry name, which is the driver entry information, such as ais_max96722 or ais_max96756, etc. For different modes of camera modules, as long as the Serdes chip model is the same, a set of driver entry information can be shared. The camera function configuration information is detailed information of the camera module, which can include the camera mode name, such as max96722_avm or max96722_dms, etc. When loading the alternative XML file, through the camera function configuration information, the specific module function of the camera can be realized under the same set of driver system. The camera configuration information includes channel, device address, frame rate, format, and resolution, etc. Using the camera configuration information, different camera types can be distinguished, and then a set of driver system can be used to drive multiple modes of cameras. When the system is built, there is a mapping relationship for GPIO, and different hardware corresponds to different GPIO. Therefore, using the GPIO information in the alternative XML file, the adaptation to different hardware platforms can be realized.

[0051] S202, generating a camera mode configuration pool by using the alternative XML file.

[0052] In some embodiments, the camera mode configuration pool contains alternative XML files of multiple vehicle types, and each vehicle type can be configured with multiple cameras. Different cameras corresponding to the Serdes chip need to be managed by ID. Through the I2C channel and device information, a link can be established to each camera. For example, there are 4 cameras in AVM mode, if the I2C channel is 1, and the device ID is 0, then the IDs of the four cameras are 01, 02, 03, and 04. For example, a link has only 2 cameras, and the device ID is 1, then the camera IDs are 10 and 11. When all camera IDs are allocated, the camera IDs can be allocated in a planned order in decimal, so as to realize the single-item configuration of the camera ID management.

[0053] In some embodiments, the same physical link can be used to support different camera modules, for example, a four-in-one interface physical link can support the display of DMS, OMS, TOF, and RVC. The advantage of such a setting is that it meets the operation of multi-modularization, simplifies the physical link and linking process, realizes platformization of the common board through integration of the driver, and through the standardized physical linking process, the alternative XML file is used to uniformly manage the hardware-related GPIO and camera channel configurations, and meets the demand of agile development.

[0054] S203, determining the vehicle type information of the current vehicle from the product off-line configuration memory of the current vehicle according to the unique part number of the current vehicle.

[0055] For example, FIG. 3 is a multi-mode driving flowchart of a vehicle camera. In FIG. 3, a unique part number is stored in the vehicle offline configuration module, and the vehicle model information (i.e., vehicle model item) corresponding to the unique part number is stored in the vehicle item configuration module.

[0056] S204. Determine a target camera configuration file from the candidate XML files in the camera mode configuration pool according to the vehicle model information.

[0057] The target camera configuration file includes driving entry information, camera function information, camera configuration information, and general input / output port (GPIO) information corresponding to the in-vehicle camera of the current vehicle.

[0058] Specifically, the camera application can be opened first, such as starting AVM, DMS, OMS, and RVC. Then, the target camera configuration file is determined from the candidate XML files in the camera mode configuration pool, which has been standardized and normalized. For example, if the vehicle model information is ABCD, the corresponding candidate XML file (i.e., the target camera configuration file) of ABCD can be accessed in the configuration pool. As shown in FIG. 3, the camera xml file (i.e., the target camera configuration file) corresponding to each vehicle model item (i.e., vehicle model information) can be determined from the multi-mode camera configuration pool (i.e., the camera mode configuration pool).

[0059] S205. Determine the driving entry of the main driver in the driver package using the driving entry information in the target camera configuration file.

[0060] Specifically, by loading the driving entry information in the target camera configuration file, the driving entry of the main driver in the driver package can be determined.

[0061] S206. Determine the target driving function from the driver package using the driving entry and the camera function information.

[0062] Specifically, in order to realize the normalization of cameras with different modes, i.e., to standardize and integrate the functions of different camera modules, the driving functions of each camera mode can be packaged to obtain a driver package. For example, if max96722 is a driver package, the driver package can include the driving programs of AVM, DMS, OMS, RVC, and TOF modes. By using the driving entry of the main driver, the target driving function can be determined from the driver package using the camera function information, which realizes that even if the configurations of the platform and the vehicle model are different, a single driving method can meet the driving needs of multiple modes under the condition of the same deserializer chip.

[0063] S207, driving the camera configured in the current vehicle by using the target driving function, the camera configuration information and the GPIO information.

[0064] Specifically, the target driving function can call a target header file.

[0065] In some embodiments, the image display process after driving can include: after the adaptation of multiple modes and the correct configuration of SerDes, opening the MIPI data stream, and the deserializer and the serializer working normally. The camera starts capturing images and converting them into a video stream, and the camera corresponding to the ID transmits the images to the upper-layer APP through the link.

[0066] In some embodiments, FIG. 4 is a schematic diagram of a camera data transmission process. As shown in FIG. 4, the camera data transmission process can include the following 10 steps:

[0067] 1) Camera end data transmission: the camera end transmits the video through the camera serial interface (CSI). This step is a protocol layer process, and the protocol layer data is processed in the physical layer through D-PHY (D is the Roman numeral 500, meaning 500 Mbits / s, and PHY means physical layer).

[0068] 2) Serializer adds series: the serializer (Serializer) physical layer accepts the camera data based on D-PHY, and simultaneously transmits the protocol layer based on CSI. Accordingly, the serializer converts the parallel signal into a serial signal.

[0069] 3) Tx Equalizer performs signal equalization: the path through which the SerDes signal from the sending end chip reaches the receiving end chip becomes a channel (Channel), which specifically includes chip packaging, PCB bus, via, cable and connector elements. From the frequency domain, the channel can be simplified as a low-pass filter model. If the rate of SerDes is greater than the channel cutoff frequency, the signal will be damaged to some extent. The role of the equalizer is to prevent the channel from damaging the signal.

[0070] 4) Data transmission: data transmission is performed based on low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS), and the data after the serializer adds series is transmitted to the deserializer.

[0071] 5) Rx Equalizer performs signal equalization: the role of the receiving end equalizer is to prevent the channel from damaging the signal when receiving the signal, and maintain the transmission stability.

[0072] 6) Deserializer Deserialization: Deserializer physical layer accepts camera data based on D-PHY, while the protocol layer is transmitted based on CSI. Accordingly, the serializer converts the serial signal into a parallel signal.

[0073] 7) Data packaging after deserialization: The data obtained after deserialization is packaged according to the MIPI protocol and transmitted to the system on chip (SOC). As shown in FIG. 3, the camera configuration module, multi-mode camera configuration module, and Serdes (i.e., SerDes) configuration module are used to drive the SerDes and SerDes chip, and finally transmit the video data collected by the camera to the SOC. The MIPI (Mobile Industry Processor Interface) protocol can be used to standardize the interfaces inside the mobile phone, such as the camera, display screen interface, and radio frequency / baseband interface, thereby reducing the complexity of mobile phone design and increasing design flexibility.

[0074] 8) Internal MIPI data analysis of SOC: The internal MIPI module of the SOC can hard-decode MIPI data, and the signal channel transmission is performed during the analysis, and the data adaptation of the interface multiplexing is performed.

[0075] 9) Signal channel processing: Since there are multiple modes of the signal channel of the camera, the target camera configuration file can be used for configuration, different signal channels are allocated for different mounting conditions, and the difference in transmission rate is processed according to the following rate formula: mbps = (w * h * fps * blank) * bpp * numVchannel

[0076] Where Mbps is the transmission bandwidth, w is the video width, h is the video length, fps is the video frame rate per second, blank is the blank part of the frame header and frame tail, bpp is the pixel depth (bits per pixel), and numVchannel is the number of communication channels.

[0077] 10) Data saving: The data is saved in double data rate synchronous dynamic random-access memory (DDR) or static random-access memory (SRAM) for use by the upper layer and display screen output, etc.

[0078] In some embodiments, if the camera is hot-plugged (i.e., connected or disconnected while the system is running) during normal display, or the camera is in an abnormal state, such as overheating or data transmission error, appropriate measures can be taken.

[0079] The multi-mode driving method of the camera provided in the embodiment of the application simplifies the complexity of the driving of the vehicle-mounted camera, reduces the difficulty and cost of the maintenance of the system, and realizes the rapid determination of the driving function of the camera in different modes. In various scenes of cross-platform, cross-vehicle factory and cross-vehicle type, the target driving function, the camera configuration information and the GPIO information can be used for each chip to realize the driving of the camera in multiple modes, simplify the complexity of the driving method of the vehicle-mounted camera, reduce the difficulty and cost of the maintenance of the system, improve the performance of the vehicle-mounted camera system, integrate the advantages of multiple platforms, enhance the stability, replicability and portability of the system, meet the conditions of agile development, and are suitable for popularization and use.
