[0048] The test platform is based on the reconstructed system framework layer and camera simulation service subsystem to realize the debugging of camera simulation data.

[0049] In the above embodiment, the platform server includes:

[0050] Definition module, used to formulate the camera kernel driver adaptation file of the camera driver module;

[0051] A configuration module is used to configure the camera kernel driver adaptation file into the operation subsystem.

[0052] In the above embodiment, the video simulation interface includes: a first reconstruction module, which is used to obtain the camera function of the camera application, and construct a camera abstract module corresponding to the camera function of the camera application in the system framework layer to meet the driving requirements of the driving layer;

[0053] A second reconstruction module is used to add a video stream adaptation server corresponding to the camera abstraction module in the camera simulation service subsystem; the video stream adaptation server is used to perform video stream decoding on the video signal to obtain original camera data;

[0054] In addition, the camera simulation service subsystem also includes: a simulation mirror building module connected to the video stream adaptation server;

[0055] The simulation image building module is used to build a simulation image for the camera abstract module after the camera application development is completed, compile it into an image file, and deploy it to a virtual environment for operation;

[0056] During operation, the camera abstraction module configures the video simulation interface and the simulation service parameters of the video simulation interface through the camera simulation service called by the camera application interface to obtain camera simulation data.

[0057] In the above embodiment, from the perspective of category, the video analog interface at least includes a physical interface and a software protocol layer interface;

[0058] The physical interface is used to configure service information; the configured service information includes service IP and service port information;

[0059] The software protocol layer interface is used to configure the number of simulated video channels, resolution, and frame rate.

[0060] The driver layer is provided with a camera driver module; the camera driver module has an input end connected to the camera application, used to receive camera data obtained by a remote video server shooting a target object in a virtual environment, and convert it into a video signal; the output end is connected to the camera abstract module, used to drive the camera abstract module;

[0061] The camera abstraction module is used to receive video signals and call the camera simulation service to perform camera data simulation.

[0062] In the above embodiment, the camera driving module includes:

[0063] A control unit, used to control the camera of the remote video server by acquiring the camera kernel driver adaptation file;

[0064] The receiving unit is used to receive the content obtained by the camera shooting the target object in the virtual environment, and transmit it back to the camera application.

[0065] In the above embodiment, the camera abstraction module receives a call instruction sent by the platform server based on the physical interface, and responds to the configuration information of the physical interface contained in the call instruction; after the camera application development is completed, the camera abstraction module calls the camera simulation service through the camera application interface, and builds a virtual environment through the video stream adaptation server and the simulation mirror construction module connected to the camera abstraction module; so that the camera abstraction module application runs in the virtual environment.

[0068] Specifically, the Camera HAL can be modified in the system architecture layer (framework) to retain the original APP interface, and the implementation method is changed to call the video data of the remote video server to perform camera data simulation. This can break away from the limitations of hardware and underlying development, enable rapid debugging, reduce the application development cycle, and save development costs.

[0069] Development process

[0070] Camera HAL-SIM needs to extend some configuration interfaces, such as:

[0071] ■Service information configuration: service IP, port, etc.

[0072] ■Video simulation configuration: video channels, resolution, frame rate, etc.

[0073] It is understandable that the above interface can be set through simulation called by the application, and can also be configured by default in the form of a configuration file.

[0074] Based on the same inventive concept, the embodiment of the present application also provides a method for a camera simulation data debugging system based on vehicle-mounted applications. The implementation scheme for solving the problem provided by the method is similar to the implementation scheme recorded in the above-mentioned system, so the specific limitations in one or more embodiments of the camera simulation data debugging method based on vehicle-mounted applications provided below can be found in the above limitations on the camera simulation data debugging system based on vehicle-mounted applications, which will not be repeated here. It can be understood that the above description of the system is also applicable to the description of the method.

[0075] In one embodiment, Figure 2 As shown, a camera simulation data debugging method based on vehicle-mounted applications is provided, the method comprising:

[0076] S101: obtaining a camera function of a camera application, constructing a camera data simulation service corresponding to the camera function of the camera application in an operating system, and reconstructing the operating system;

[0077] S102 receives the camera simulation data obtained by the reconstructed operating system by calling the camera simulation service, configuring the video simulation interface and the simulation service parameters of the video simulation interface, and performs debugging of the camera simulation data.

[0078] In the simulation debugging method proposed in the above embodiment, the simulation mode can also be extended to other data simulations, such as simulating CAN and vehicle Ethernet data. The main purpose of this method is to simplify the debugging process of the application and improve development efficiency. The authenticity of the data depends on the capabilities of the video server, which is not within the scope of this method.

[0079] The above method is an extended function of the test platform. The platform server provides a video simulation interface, including a physical interface and a software protocol layer interface. This time, the software protocol interface is used for further expansion. By developing a video stream adaptation server and a hardware abstraction layer of the operating system layer, the original video simulation interface is directly connected to the operating system, eliminating the intermediate layers of processing. When implementing camera application development, data debugging can be performed directly without waiting for the completion of the development of the intermediate layer, such as the content on the architecture diagram, and it does not depend on the system development progress and the remote camera driver development progress. The developed Camera-HAL-SIM can also be compiled into ROM, and real data joint debugging can be achieved in the virtual machine environment, which can greatly improve the development and debugging efficiency.
