However, the display effect of the instrumentation system is more and more complex and 3D rendering effect is required, so a hardware GPU is required for graphics rendering. The method for realizing the dual systems realizes the condition of calling failure due to different calling formats of the QT and the GPU when the instrument system performs graphic rendering through the GPU and a GPU hardware interface is called dynamically; and in a hardware isolation manner, the operating efficiency of the device may be reduced. Therefore, the conventional scheme has a problem that the robustness of the graphic processing of the dual system is poor.
In order to solve the above problems, the present application provides a dual-system graphics processing method, apparatus, and terminal, where a first graphics processing function library obtained by copying a second graphics processing function library in a second operating system is called by a first operating system through an interface of an adaptation library to achieve the purpose of using the first graphics processing function library in the first operating system, and a GPU driver is called by the first graphics processing function library, so that the problem of poor robustness of graphics processing of a dual system due to different calling formats of the first operating system and the second operating system is overcome, and the robustness of graphics processing of the dual system is further improved.

The container effectively partitions resources managed by a single operating system into isolated groups to better balance conflicting resource usage requirements among the groups. An application runs in each container, different containers are isolated from each other, and a communication mechanism can be established between the containers.
Virtualization: the resource management technology is used for abstracting and converting various entity resources of a computer, such as a server, a network, a memory and the like, and then presenting the resources so that a user can apply the resources in a better mode. The virtualization target is often to run multiple systems or applications on the same host, thereby improving the utilization rate of resources, reducing the cost, and facilitating management and fault tolerance.
Virtualization at the operating system level: meaning that the kernel isolates different processes by creating multiple virtual operating system instances, such as the kernel and libraries. Docker and other container technologies fall into this category.
The traditional virtualization mode is as follows: the virtualization is realized on a hardware level, and an additional virtual machine management application layer and a virtual machine operating system layer are needed. The Docker container realizes virtualization on the operating system level, directly multiplexes a local host operating system, and is lighter. The Docker container realizes virtualization on the operating system level, directly multiplexes a local host operating system, and is lighter.
A container: refers to an environment like the Linux system for running and isolating applications. When the container is started from the mirror, the Docker will create a writable layer on the top layer of the mirror, and the mirror itself is read-only and remains unchanged.

On the basis of the above-described embodiment, the structure of the dual system in the processing apparatus provided in the application example will be described below. Fig. 4 is a schematic structural diagram of a dual system in a terminal device according to an embodiment of the present application, and as shown in fig. 4, the terminal device includes: a main operating system 301, a driver device 302, a first operating system 303, and a second operating system 303. In the application, a first operating system 303 and a second operating system 303 are set in a main operating system 301 according to an LCX technology, the first operating system 303 and the second operating system 303 are independent from each other, a graphics processing function library is stored in the first operating system 303 and the second operating system 303 respectively, the first operating system 303 and the second operating system 303 call a hardware device of a GPU in a driver device 302 through the graphics processing function library, and the GPU is driven by a GPU driver to perform graphics processing.
Specifically, in the method for implementing dual-system graphics processing by using a terminal device, for a first operating system 303, a user firstly clicks an application program to trigger a graphics processing request, then calls an interface of an open graphics library through the graphics processing request, then calls an interface in a graphics processing function library through an interface function of the open graphics library, performs function encapsulation to form a library function to implement a specific function, then calls a hardware interface of a graphics processor through the library function to implement graphics processing, then returns the obtained first display interface data to the adaptation library, and generates a first display request through a graphics display interface in the adaptation library, where the first display request is used to request a display device to display the first display interface data.
Wherein, the open graphics library may be OpenGL; the adaptation library may be libhybris, the graphics processing function library may be libEGL, and the library function may be libEGL.
Further, in the method for implementing dual-system graphics processing by a terminal device, for the second operating system 304, a user first clicks an application program to trigger a graphics processing request, then calls an interface of an open graphics library through the graphics processing request, then opens the graphics library to call an interface in a graphics processing function library, encapsulates functions into library functions to implement specific function functions, then calls a hardware interface of a graphics processor through the library functions to implement graphics processing, then returns the obtained second display interface data to the graphics processing function library, and generates a second display request through the graphics display interface in the graphics processing function library, where the second display request is used to request the display device to display the second display interface data.
