Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The term "module" as used herein may be considered a software object executing on the computing system. The various components, modules, engines, and services described herein may be viewed as objects implemented on the computing system. The apparatus and method described herein are preferably implemented in software, but may also be implemented in hardware, and are within the scope of the present application.
Referring to fig. 1, fig. 1 is a System architecture diagram of an electronic device according to an embodiment of the present invention, where the System architecture is an Android System architecture, and in an embodiment, the System architecture may also be an apple (IOS) System framework. The android system architecture is an architecture of an android system, the android system architecture is the same as an operating system of the android system, a layered architecture is adopted, the layered architecture is divided into four layers, and an android Application layer (Application), an android Application Framework layer (Application Framework), an android system running layer and a Linux kernel layer are respectively arranged from high to low.
An application layer: the application is a program written in java language running on a virtual machine, such as a camera application, Email client, SMS short message program, calendar, and the like.
An application framework layer: this layer is an Application Programming Interface (API) framework used when writing core applications published by Google (Google), and developers can also use these frameworks to develop their own applications, which simplifies the structural design of program development but must comply with the development principles of the framework.
A system runtime (C/C + + library and android runtime) layer: when the android application framework is used, the android system can support various components used by us through some C/C + + libraries, so that the android system can better serve us, such as SQLite (relational database) and Webkit (Web browser engine) in the android application framework.
A Linux kernel layer: the android core system service is given to a linux2.6 kernel, and security, memory management, process management, a network protocol stack, a drive model and the like all depend on the kernel, such as a Binder IPC (Internet process connection, inter-process communication) drive, and a special driver of the android has a separate device node and provides the inter-process communication function.
Information transfer between applications different from each other, such as image information transfer between a camera application and a third-party application (e.g., an AR application), first needs to call image information stored in an image memory space to a camera client (camera client) through a camera Service layer (camera Service) of the camera application, and finally reaches a Software Development Kit (SDK) of the camera application, and the image information is cross-process transferred to the AR application through a Binder communication manner, and the AR application can perform augmented reality rendering after receiving the image information, thereby implementing an augmented reality function. It should be noted that Binder is an android cross-process communication mode, when image information is large, transmission efficiency is low, so that waiting time of AR application is too long, and running speed of AR application is reduced, so that cross-process is required because in general, memory cannot be shared between application programs in an android system. Data exchange between different applications is a cross-process.
The following is a detailed description of the analysis.
In the present embodiment, the description will be made from the perspective of a transmission device of image information, which may be specifically integrated in an electronic device, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
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 the software development kit is generally a collection of development tools used by some software engineers to build application software for a specific software package, software framework, hardware platform, operating system, and the like.
The camera application functions to call a camera on the terminal to perform real-time shooting, and convert optical image information into an electric signal for storage or transmission. The Memory space is also called an internal Memory, and is used to temporarily store operation data in a Central Processing Unit (CPU) and data exchanged with an external Memory such as a hard disk.
The software development kit corresponding to the camera application is a set of relevant documents, examples and tools for assisting in developing the camera application, and the image memory space corresponding to the camera application can be shared to third-party applications by adjusting the API, the dynamic link library, the import library and the like of the software development kit corresponding to the camera application. That is to say, the third party application can call the image information in the image memory space quickly.
In some embodiments, the step of adjusting the corresponding software development kit in the camera application may include adjusting access rights of the image memory space of the camera application through the software development kit, and opening sharing rights of the image memory space of the camera application to third-party applications.
The access right of the image memory space of the camera application can be modified correspondingly through the SDK, if the access right is closed by default, the access right is adjusted to be open, and therefore the third-party application can acquire the sharing right corresponding to the image memory space of the camera application.
In step S102, an image memory space is obtained, and handle information corresponding to the image memory space is determined.
Wherein the handle information is a unique integer value used, i.e., a 4-byte (8-byte in a 64-bit program) long value, to identify different objects in the application program and different instances in the same class, such as a window, button, icon, scroll bar, output device, control or file. And acquiring storage address information corresponding to the image memory space, and determining a corresponding numerical value with the length of 4 bytes or 8 bytes.
Accordingly, the application can access information of the corresponding object through the handle. That is, the storage address corresponding to the image memory space can be found through the handle information corresponding to 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 step of obtaining the image memory space and determining the handle information corresponding to the image memory space may include:
(1) determining the first address and the number of memory addresses corresponding to the image memory space;
(2) and determining handle information corresponding to the image memory space according to the first address and the number of the memory addresses.
The image memory space is composed of a plurality of memory addresses for storing image information, one memory address is a number and represents one memory space, and one memory address represents one byte (byte) which is 8-bit storage space. The camera application stores the image information acquired in real time in the memory, and the memory can allocate a corresponding number of memory addresses according to the data size of the image information.
Therefore, the whole image memory space can be determined only by determining the first address and the number of the memory addresses corresponding to the image memory space, and handle information representing the image memory space can be generated according to the first address and the number of the memory addresses.
In some embodiments, the determining the first address and the number of memory addresses corresponding to the image memory space may include:
(2.1) determining a memory block corresponding to the image memory space;
and 2.2, analyzing the memory address corresponding to each memory block to obtain the corresponding first address and the number of the memory addresses.
The method comprises the steps of determining memory blocks of all image information of an image memory space on a memory, and analyzing memory addresses corresponding to the memory blocks to obtain a first address corresponding to the memory addresses and the total number of the memory addresses.
In step S103, when the image transmission instruction of the third-party application is detected, the handle information is loaded to determine the corresponding image memory space.
The third-party application is other applications other than the camera application, such as an AR application, and since the AR application is an application that renders a corresponding augmented reality image according to a position, i.e., an angle, photographed by a camera, the AR application needs to call image information acquired by the camera application in real time.
Therefore, when it is detected that the AR application needs to call the image information, an image transmission instruction is generated, that is, when an image transmission instruction of a third-party application is detected, handle information generated according to the image memory space is loaded, and a memory address corresponding to the image memory space is acquired, so as to determine the corresponding image memory space.
In some embodiments, the step of loading the handle information to determine the corresponding image memory space may include:
(1) determining the initial address of the image memory space according to the first address in the handle information;
(2) and traversing according to the number of the memory addresses based on the initial address to obtain a corresponding image memory space.
The terminal can determine the initial address of the image memory space according to the initial address in the handle information, the initial address is the initial address of the image information contained in the image memory space, traversal is performed according to the total number of the memory addresses based on the initial address, and the image information in the whole 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 the third-party application.
The terminal can access the image memory space in real time, and the image memory space has sharing authority, so that 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.
As can be seen from the above, in the transmission method of image information provided in this embodiment, the image memory space of the image stored by the camera application is shared to the third-party application by adjusting the corresponding software development kit in the camera application; acquiring an image memory space, and determining handle information corresponding to the image memory space; when an image transmission instruction of a third-party application is detected, loading handle information to determine a corresponding image memory space; and accessing the image memory space to transmit the image information in the image memory space to a third-party application. Therefore, when the third-party application calls the image information of the camera application, the image information stored in the camera application can be directly loaded from the memory space according to the handle information, so that inconvenience caused by cross-process transmission is avoided, the transmission time of the image information is saved, and the transmission efficiency of the image information is improved.
The method described in the above embodiments is further illustrated in detail by way of example.
Referring to fig. 3, fig. 3 is another schematic flow chart of a method for transmitting image information according to an embodiment of the present disclosure.
Specifically, the method comprises the following steps:
in step S201, the access right of the image memory space of the camera application is adjusted through the software development kit, and the sharing right of the image memory space of the camera application to the third-party application is opened.
For better explanation of the embodiment, the terminal is explained by using a mobile phone, a system as an android system, and a third-party application as an AR application.
Because the applications in the android system cannot share the memory, the mobile phone needs to modify the access permission 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 can directly call the image memory space from the memory at the later stage.
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 for storing the image in the SDK in the camera application layer 3 is shared with the augmented reality server 4 of the AR application, so that after the image information is transmitted to the camera client through the camera server and reaches the application SDK, the image information is not required to be transmitted to the augmented reality server through a Binder cross-process communication mode, but can be shared through the image memory space, and the image information in the image memory space in the mobile phone memory is directly called.
In step S202, an image memory space is obtained, and a first address and a memory address number corresponding to the image memory space are determined.
The mobile phone obtains the attribute information of the image memory space, and because 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 the memory addresses corresponding to the image memory space, where the first address is the first memory address for storing the image information, and the number of the memory addresses is the total number of the memory addresses.
In step S203, handle information corresponding to the image memory space is determined according to the first address and the number of memory addresses.
The mobile phone can generate handle information corresponding to the image memory space according to the first address and the number of the memory addresses, the image information in the image memory space can be found through the handle information, and the handle information can be correspondingly updated according to the change of the memory addresses, so that the corresponding position of the specific image information in the memory can be found only by knowing the handle information.
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.
When the AR application is detected to call the image information in the camera application, an image transmission instruction is generated, namely when the AR application is judged to call the image information in the camera application, a first address of the handle information is obtained, and a starting address of an image memory space is determined according to the first address.
In step S205, traversal is performed according to the number of memory addresses based on the start address to obtain a corresponding image memory space.
The method comprises the steps of traversing according to the number of memory addresses based on the initial address of the image memory space to obtain all the memory addresses storing the image information applied by the camera, and obtaining the image memory space storing the image information applied by the camera.
In step S206, the image memory space is accessed to transmit the image information in the image memory space to the third-party application.
The sharing authority is opened in the image memory space, so that the mobile phone can directly access the image memory space, call the image information in the image memory space and transmit the image information to the AR application, and the AR application can acquire the image information in the camera application in real time and quickly and render the image called in real time.
As can be seen from the above, in the transmission method of image information provided in this embodiment, the access right of the image memory space applied by the camera is adjusted by the SDK, the sharing right of the image memory space applied by the camera to the AR application is opened, the image memory space is obtained, the corresponding handle information is determined according to the head address and the number of the memory addresses corresponding to the image memory space, when an image transmission instruction of a third-party application is detected, the start address of the image memory space is determined according to the head address in the handle information, traversal is performed according to the number of the memory addresses, the image memory space is obtained, the image memory space is accessed, and the image information in the image memory space is transmitted to the third-party application. Therefore, when the third-party application calls the image information of the camera application, the image information stored in the camera application can be directly loaded from the memory space according to the handle information, so that inconvenience caused by cross-process transmission is avoided, the transmission time of the image information is saved, and the transmission efficiency of the image information is improved.
In order to better implement the image information transmission method provided by the embodiment of the present application, the embodiment of the present application further provides a device based on the image information transmission method. The terms are the same as those in the above-mentioned transmission method of image information, and details of implementation may refer to the description in the method embodiment.

The determining unit 32 obtains the storage address information corresponding to the image memory space, and determines the corresponding value 4 bytes or 8 bytes long.
Accordingly, the application can access information of the corresponding object through the handle. That is, the storage address corresponding to the image memory space can be found through the handle information corresponding to the image memory space, that is, the memory address corresponding to the image memory space can be quickly found through the handle information.
The loading unit 33 is configured to, when an image transmission instruction of a third-party application is detected, load the handle information to determine a corresponding image memory space.
The third-party application is other applications other than the camera application, such as an AR application, and since the AR application is an application that renders a corresponding augmented reality image according to a position, i.e., an angle, photographed by a camera, the AR application needs to call image information acquired by the camera application in real time.

In some embodiments, the loading unit 33 is specifically configured to determine a starting address of the image memory space according to a first address in the handle information, and perform traversal according to the number of memory addresses based on the starting address to obtain a corresponding image memory space.
And the transmission unit 34 is configured to access the image memory space to transmit the image information in the image memory space to a third-party application.
The transmission unit 34 can access the image memory space in real time, and because the image memory space has a sharing right, the transmission unit 34 can transmit the image information in the memory space to the AR application in real time, so that the Binder communication process is saved.
