detailed description

Please refer to the drawings, in which the same component symbols represent the same components. The principle of the present application is illustrated by implementing in an appropriate computing environment. The following description is based on the exemplified specific embodiments of the present application, which should not be construed as limiting other specific embodiments not detailed herein.

The term "module" as used herein can be considered as a software object executing on the computing system. The different components, modules, engines, and services described in this article can be considered as implementation objects on this computing system. The device and method described herein are preferably implemented in software, and of course, they can also be implemented in hardware, which are all within the protection scope of this application.

Please refer to FIG. 1. FIG. 1 is a system architecture diagram of an electronic device running according to an embodiment of the present invention. The system architecture is an Android system architecture. In one embodiment, the system architecture may also be Apple (iphone Operating System). , IOS) system framework. The Android system architecture is the Android system architecture. The Android system architecture, like its operating system, uses a layered architecture that is divided into four layers. From high to low are the Android application layer and the Android application framework. Layer (Application Framework), Android system running layer and Linux kernel layer.

Application layer: An application is a program written in the Java language and running on a virtual machine, such as a camera application, Email client, SMS short message program, and calendar.

Application framework layer: This layer is an application programming interface (API) framework used when writing core applications published by Google. Developers can also use these frameworks to develop their own applications, which simplifies Structural design of program development, but must adhere to the development principles of its framework.

System runtime (C / C ++ library and Android runtime) layer: When using the Android application framework, the Android system will support various components we use through some C / C ++ libraries to make it better serve us, such as among them SQLite (Relational Database), Webkit (Web Browser Engine).

Linux kernel layer: Android's core system services are given to the Linux 2.6 kernel, such as security, memory management, process management, network protocol stack, and driver model, etc. all depend on this kernel, such as the Binder IPC (Internet Process Connection Connection) driver , A special driver for Android, with a separate device node that provides inter-process communication.

Among them, the information transfer between different applications, such as the image information transfer between camera applications and third-party applications (such as AR applications), first needs to be stored in the image memory space through the camera application service layer (camera Service). The image information is transferred to the camera client, and finally arrives in the Software Development Kit (SDK) of the camera application. Through the Binder communication method, the image information is transmitted to the AR application across processes, and the AR application After receiving the image information, it can perform augmented reality rendering to achieve the function of augmented reality. It should be noted that Binder is an Android cross-process communication method. When the image information is large, the transmission efficiency is low, which will cause the AR application to wait too long and cause the AR application to run at a reduced speed. The reason why cross-process is needed is Under normal circumstances, memory cannot be shared between applications in the Android system. The data exchange between different applications is called cross-process.

Specific analysis and description are given below.

In this embodiment, description will be made from the perspective of a transmission device of image information, and the transmission device of image information may be specifically integrated into an electronic device, such as a mobile phone, a tablet computer, a personal digital assistant (PDA, Personal Assistant), and the like.

An embodiment of the present invention provides a method for transmitting image information, including:

In an implementation manner, the step of determining corresponding handle information of the image memory space may include:

Determining the first address and the number of memory addresses corresponding to the image memory space;

Determining corresponding handle information of the image memory space according to the first address and the number of memory addresses.

In one embodiment, the step of determining the first address and the number of memory addresses corresponding to the image memory space may include:

Analyze the memory address corresponding to each memory block to obtain the corresponding first address and the number of memory addresses.

In an implementation manner, the step of loading the handle information to determine a corresponding image memory space may include:

Determining a start address of the image memory space according to a first address in the handle information;

Traverse according to the number of memory addresses based on the starting address to obtain a corresponding image memory space.

In one embodiment, the step of adjusting a corresponding software development kit in the camera application so that the image memory space of the image saved by the camera application is shared with a third-party application may include:

The access right of the image memory space of the camera application is adjusted through the software development kit, and the sharing permission of the image memory space of the camera application to the third-party application is opened.

By adjusting the programming interface, dynamic link library, and import library of the corresponding software development kit of the camera application, the corresponding image memory space of the camera application is shared to third-party applications.

In one embodiment, the third-party application is an augmented reality application. When an image transmission instruction of the third-party application is detected, the step of loading the handle information to determine a corresponding image memory space may include:

When it is detected that the AR application needs to retrieve image information, an image transmission instruction is generated;

Load the handle information according to the image transmission instruction, and obtain a corresponding memory address of the image memory space to determine the corresponding image memory space.

An embodiment of the present application provides a method for transmitting image information. As shown in FIG. 2, the method for transmitting image information may include the following steps:

In step S101, the corresponding software development kit in the camera application is adjusted.

It should be noted that this software development kit is generally a collection of development tools used by some software engineers to build application software for specific software packages, software frameworks, hardware platforms, operating systems, and so on.

Among them, the function of the camera application is an application that calls a camera on a terminal for real-time shooting, and converts optical image information into electrical signals for storage or transmission. In order to facilitate management, the camera application generally stores image information obtained by the camera application in real time. To a preset memory space, such as the image memory space. It should be noted that the memory space is also called internal memory, and its function is to temporarily store the operation data in the central processing unit (CPU) and data exchanged with external memories such as hard disks.

The corresponding software development kit for the camera application is a collection of related documents, examples, and tools to assist in the development of the camera application. By adjusting the API, dynamic link library, and import library of the corresponding software development tool kit for the camera, The corresponding image memory space of the camera application can be shared with third-party applications. In other words, the third-party application can quickly call the image information in the image memory space.

In some embodiments, the step of adjusting the corresponding software development kit in the camera application may include adjusting the access right of the image memory space of the camera application through the software development kit, and opening the image memory space of the camera application to the first Sharing permissions for third-party applications.

The access right of the image memory space of the camera application can be modified correspondingly through the SDK. For example, if the access right is closed by default, it is adjusted to be open so that the third-party application can obtain the sharing permission corresponding to the image memory space of the camera application.

In step S102, an image memory space is acquired, and corresponding handle information of the image memory space is determined.

Among them, the handle information is a unique integer value, that is, a 4-byte (8-byte in a 64-bit program) value, to identify different objects in the application and different instances in the same category, such as , A window, button, icon, scroll bar, output device, control, or file. Obtain the storage address information corresponding to the image memory space, and determine the corresponding 4-byte or 8-byte value.

Therefore, the application can access the information of the corresponding object through the handle. That is, the corresponding storage address of the image memory space can be found through the corresponding handle information of the image memory space, that is, the memory address corresponding to the image memory space can be quickly found through the handle information.

In some embodiments, the steps of obtaining image memory space and determining handle information corresponding to the image memory space may include:

(1) Determine the first address and the number of memory addresses corresponding to the image memory space;

(2) Determine the corresponding handle information of the image memory space according to the first address and the number of memory addresses.

The image memory space is composed of multiple memory addresses for storing image information. A memory address is a number, which represents a memory space, and a memory address represents a byte, that is, a storage space of 8 bits. The camera application stores the image information obtained in real time on the memory, and the memory allocates a corresponding number of memory addresses according to the data size of the image information.

Therefore, only the first address and the number of memory addresses corresponding to the image memory space can be determined to determine the entire image memory space, and the corresponding handle information representing the image memory space can be generated based on the first address and the number of memory addresses.

In some embodiments, the step of determining the first address and the number of memory addresses corresponding to the image memory space may include:

(2.1) determine the memory block corresponding to the image memory space;

(2.2) Analyze the memory address corresponding to each memory block to obtain the corresponding first address and the number of memory addresses.

Among them, the memory blocks of all the image information in the image memory space on the memory are determined, and the memory address corresponding to each memory block is analyzed to obtain the corresponding first address of the memory address and the total number of memory addresses.

In step S103, when an image transmission instruction of a third-party application is detected, the handle information is loaded to determine a corresponding image memory space.

The third-party application is a non-camera application, such as an AR application. Since an AR application is an application that renders a corresponding augmented reality image based on the camera ’s shooting position, that is, the angle, the AR application needs to call the camera application in real time. Image information.

Therefore, when it is detected that the AR application needs to retrieve image information, an image transmission instruction is generated, that is, when an image transmission instruction of a third-party application is detected, the handle information generated according to the image memory space is loaded to obtain the corresponding memory address of the image memory space. To determine the corresponding image memory space.

In some embodiments, the step of loading handle information to determine a corresponding image memory space may include:

(1) Determine the starting address of the image memory space according to the first address in the handle information;

(2) Traversing according to the number of memory addresses based on the starting address to obtain the corresponding image memory space.

The terminal can determine the start address of the image memory space according to the first address in the handle information, and the start address is the start address of the image information contained in the image memory space. Based on the start address, the total number of memory addresses is based on the start address. By traversing, the image information in the entire image memory space can be obtained.

In step S104, the image memory space is accessed to transmit the image information in the image memory space to a third-party application.

The terminal can access the image memory space in real time. Because the image memory space has sharing permissions, the terminal can transmit the image information in the memory space to the AR application in real time, thereby saving the process of Binder communication. Because Binder communication requires the camera application to transfer image information to the AR application across processes, the process of the AR application will be suspended during the image information transmission process, that is, there is a waiting time, so it will affect the smoothness of the use of the AR application. In the embodiment of the present invention, the AR application directly calls the image information in the memory, which can save the waiting time of the image information.

It can be known from the foregoing that the image information transmission method provided in this embodiment adjusts the corresponding software development kit in the camera application so that the image memory space of the image saved by the camera application is shared with the third-party application, and the image memory space is obtained. Determine the corresponding handle information of the image memory space; when the third-party application image transfer instruction is detected, load the handle information to determine the corresponding image memory space; access the image memory space to transfer the image information in the image memory space to the first Three-party application. In this way, when the third-party application calls the image information of the camera application, the image information stored by the camera application can be directly loaded from the memory space according to the handle information, which avoids the inconvenience caused by cross-process transmission and saves the transmission time of image information. , Thereby improving the transmission efficiency of image information.

According to the method described in the above embodiment, an example will be further described in detail below.

Please refer to FIG. 3, which is a schematic flowchart of another image information transmission method according to an embodiment of the present application.

Specifically, the method includes:

In step S201, the access right of the image memory space of the camera application is adjusted by using a software development kit, and the image memory space of the camera application is opened to the sharing authority of the third-party application.

It should be noted that, in order to better describe this embodiment, the terminal is described by using a mobile phone, a system as an Android system, and a third-party application as an AR application.

Among them, since the memory cannot be shared between applications in the Android system, the mobile phone needs to modify the access right of the image memory space of the camera application through the SDK, and open the sharing permission of the image memory space of the camera application to the AR application, so that the AR application The image memory space can be directly called from the memory later.

As shown in FIG. 4, after the image information is transmitted to the camera client 2 through the camera server 1 and reaches the SDK, the image memory space applied for saving the image in the SDK in the camera application layer 3 is shared to the augmented reality server 4 of the AR application. Therefore, after the image information is transmitted to the camera client through the camera server and reaches the application SDK, the image information does not need to be transmitted to the augmented reality server through the Binder cross-process communication method. Instead, the image memory space can be shared to directly access the phone memory. Image information in the image memory space.

In step S202, an image memory space is acquired, and a first address and a number of memory addresses corresponding to the image memory space are determined.

The mobile phone obtains attribute information of the image memory space. Since the mobile phone digitizes the image information in the image memory space, the mobile phone knows where the image information is stored in the memory. Based on this, the mobile phone can determine the first address and the number of memory addresses corresponding to the image memory space. The first address is the first memory address where the image information is stored, and the number of memory addresses is the total number of memory addresses.

In step S203, the corresponding handle information of the image memory space is determined according to the first address and the number of memory addresses.

The mobile phone can generate the corresponding handle information of the image memory space according to the first address and the number of memory addresses. The handle information can be used to find the image information in the image memory space. The handle information will be updated according to the change of the memory address. So only need to know the handle information, you can find the corresponding position of the specific image information in memory.

In step S204, when the image transmission instruction of the third-party application is detected, the start address of the image memory space is determined according to the first address in the handle information.

Among them, when it is detected that the AR application calls the image information in the camera application, an image transmission instruction is generated, that is, when it is determined that the image transmission instruction of the third-party application is detected, the first address of the handle information is obtained, and the first address is used to determine the image memory space. starting address.

In step S205, a traversal is performed according to the number of memory addresses based on the start address to obtain a corresponding image memory space.

The traversal is performed based on the starting address of the image memory space according to the number of memory addresses, and all the memory addresses storing the image information of the camera application are obtained, that is, the image memory space storing the image information of the camera application is obtained.

In step S206, the image memory space is accessed to transfer the image information in the image memory space to a third-party application.

Among them, because the image memory space is open for sharing permissions, the mobile phone can directly access the image memory space, and transfer the image information in the image memory space to the AR application, so that the AR application can obtain it in real time and quickly The image information in the camera application, and render the image retrieved in real time.

From the above, it is known that the image information transmission method provided in this embodiment adjusts the access right of the image memory space of the camera application through the SDK, opens the image memory space of the camera application to the AR application's sharing permission, and obtains the image memory space. The corresponding handle information is determined according to the first address corresponding to the image memory space and the number of memory addresses. When an image transfer instruction of a third-party application is detected, the start address of the image memory space is determined according to the first address in the handle information, and the memory address is determined according to the memory address. The number is traversed to obtain the image memory space, access the image memory space, and transfer the image information in the image memory space to the third-party application. In this way, when the third-party application calls the image information of the camera application, the image information stored by the camera application can be directly loaded from the memory space according to the handle information, which avoids the inconvenience caused by cross-process transmission and saves the transmission time of image information. , Thereby improving the transmission efficiency of image information.
