In one embodiment, as shown in fig. 2, there is provided a method for optimizing vehicle-mounted image display, which is described by taking the application of the method to the terminal in fig. 1 as an example, and includes the following steps:
step 202, a data display request of a browser is obtained, wherein the data display request carries a data identifier.
The terminal is pre-provided with an operating system, and the operating system is pre-deployed with a browser. The browser may be a browser that supports rendering web pages. The webpage is rendered through the browser, so that more complete data display can be performed in the webpage. The terminal can acquire a data display request of a user on the browser. The data display request may be a data display request generated by the terminal encapsulating the data selected by the user through an http protocol. The selected data may be vehicle-mounted data for a preset period of time in which playback is required. And the terminal analyzes the data display request to obtain a data identifier. The data identification may include data ID (Identity document).
Step 204, jumping from the current page of the browser to a corresponding target webpage according to the data display request, wherein the target webpage comprises a visualization application.
And 206, running the visualization application through the browser, and transmitting the data identification to the visualization application.

And the terminal jumps to the corresponding target webpage from the current webpage of the browser according to the data display request. The target web page includes a visualization application therein. The visualization application is wasm files obtained by compiling preset application scripts, and wasm files are binary files which can be run on an operating system with a browser.
The terminal can identify whether the updated version exists in the visualization application in the target webpage according to the data display request. When the visual application has an updated version, the visual application of the updated version is run through the browser. And when the visual application does not have an updated version, running the visual application in the cache resource through the browser. When the visual application is operated through the browser, the browser can transmit the data identification to the visual application, and further obtain corresponding vehicle-mounted data in the server according to the data identification through the visual application, and display the vehicle-mounted data.
And step 208, generating a data acquisition request according to the data identifier through the visualization application, and sending the data acquisition request to the server.
And 210, receiving vehicle-mounted data corresponding to the data acquisition request returned by the server through the visualization application.

The encapsulated data may include a data identifier, a header file, an interface identifier, status data of the terminal, etc. After receiving the data acquisition request, the server analyzes the data acquisition request according to a preset protocol, and can obtain a data identifier, an interface identifier and the like. The server calls an interface corresponding to the interface identifier, and obtains vehicle-mounted data corresponding to the data identifier in the cloud through the interface. The in-vehicle data may be data within a preset period of time. The vehicle-mounted data may include a running speed, a running mileage, position information, map information, etc. of the vehicle during the automatic driving. Through the cloud storage data, the data can be guaranteed not to be lost, and the safety of the data is improved. And the terminal receives the vehicle-mounted data returned by the server through the visualization application.
And 212, rendering the vehicle-mounted data through a browser, and displaying the rendered vehicle-mounted image on a visual application.
The terminal converts the received vehicle-mounted data through the visual application to obtain corresponding index data.

Because the vehicle-mounted data is data in a preset time, rendering the index data, namely page rendering, through the browser, so that a multi-frame vehicle-mounted image can be generated, and the multi-frame vehicle-mounted image is displayed through visual application. Page rendering refers to a process of parsing html (hyper text markup language ) through rules defined by CSS (CASCADING STYLE SHEETS, cascading style sheet) to achieve page drawing.
In the traditional mode, the same version of visual application can only run in a specific operating system, when the visual application needs to run on other operating systems, different visual application versions need to be packed according to the corresponding operating systems to display the vehicle-mounted image, so that unnecessary manpower and material resource consumption exists when the existing visual application runs across platforms. In this embodiment, the terminal obtains a data display request of the browser, where the data display request carries a data identifier. And jumping from the current page of the browser to a corresponding target webpage according to the data display request, wherein the target webpage comprises a visualization application. And the visual application is operated through the browser, and the data identification is transmitted to the visual application. And generating a data acquisition request according to the data identifier through the visualization application, sending the data acquisition request to the server, and receiving vehicle-mounted data corresponding to the data acquisition request returned by the server. And rendering the vehicle-mounted data through a browser, and displaying the rendered vehicle-mounted image on the visual application. Because the visual application is embedded in the target webpage, the visual application can be run on the browser, so that the same version of visual application is run on a plurality of operating systems provided with the browser, corresponding visual application versions do not need to be packed for each operating system, unnecessary manpower and material resource consumption in the vehicle-mounted image display process is avoided, vehicle-mounted data is rendered through the browser and displayed on the visual application, and the effective optimization of the traditional vehicle-mounted image display mode is realized.
In one embodiment, as shown in fig. 3, the method further includes a step of developing the visualization application, specifically including:
step 302, acquiring a preset application script, and converting the preset application script into a cpp file.
And 304, compiling the cpp file to obtain wasm files, a glue script and an html page, and taking the wasm files as the visual application, wherein the glue script and the html page are used for running the visual application through a browser.
Before acquiring the data display request of the browser, the terminal can develop a visual application capable of running on the browser in advance. The terminal acquires a preset application script, wherein the preset application script can be a visualization application script based on units, and the preset application script is written by C#. C# is an object oriented programming language. The visual application corresponding to the preset application script can only run in a specific operating system and cannot run in a browser. The terminal converts the preset application script into CPP file through IL2CPP (INTERMEDIATE LANGUAGE TO C ++, intermediate language). cpp files are source code file formats written in the C++ language (C plus plus, medium language).
The terminal then compiles the cpp file via emscripten compiler, resulting in wasm file, glue script, and html (hyper text markup language ) pages. wasm files can run in JavaScript. JavaScript is an transliteration scripting language that can be run on a browser, i.e. wasm files are run on the browser, enabling visual applications to be run on the browser. The glue script and html page are used to run the visualization application through the browser. The glue script is a JavaScript file, and is used for connecting incompatible software components, namely connecting JavaScript and wasm, so as to realize interaction between the JavaScript and wasm. The html page is used to run wasm files in the browser.
In this embodiment, the terminal converts the preset application script into the cpp file by acquiring the preset application script. Compiling the cpp file to obtain wasm file, glue script and html page, and using wasm file as visual application, wherein the glue script and html page are used for running visual application through browser. The cpp file is in a source code file format written in C++ language (C plus plus, medium-level language), and is compiled into wasm files which can be run in a browser, so that the same version of visual application can be run on a plurality of operating systems provided with the browser, corresponding visual application versions do not need to be packed for each operating system, and unnecessary consumption of manpower and material resources is avoided.
In one embodiment, the operation of the visual application through the browser comprises the steps of identifying the visual application through the browser according to the glue script, and operating the identified visual application on the html page through the browser.
Before acquiring a data display request of a browser, the terminal converts a preset application script into a cpp file and compiles the cpp file into wasm files. During compiling, a glue script and an html page are also obtained. The terminal takes wasm files as visual application. The JavaScript is operated in the browser, the browser can identify the visual application through the glue script, and the visual application is connected with the JavaScript to realize interaction. And the browser runs wasm the file through the html page.
In this embodiment, the visual application is identified by the browser according to the glue script, and the identified visual application is run on the html page by the browser. Because the visual application exists in wasm file format, the browser cannot directly identify wasm files, the visual application is favorably identified by the browser through the glue script, and the visual application is operated on an html page generated in the compiling process, so that wasm files can be stably operated on the browser.
In one embodiment, before the visual application is operated through the browser, the method further comprises the steps of sending a data display request to the server through the browser, receiving response information returned by the server, identifying whether the visual application has an updated version according to the response information through the browser, acquiring the visual application of the updated version from the server through the browser when the updated version exists, operating the visual application of the updated version, and operating the visual application in the cache resource through the browser when the updated version does not exist.
Before the terminal runs the visual application through the browser, the terminal can identify whether the visual application in the target webpage is updated. Specifically, when the browser acquires the data display request, the data display request is sent to the server so as to receive response information returned by the server. The data display request may be an http request generated according to an http protocol. Correspondingly, the response information returned by the server is http response information. And the browser analyzes the response information to obtain an http response head. The browser identifies whether the state of the visualization application has changed, i.e. whether the visualization application has an updated version, according to the ETag (ENTITY TAG ) field in the http response header. When the value of the ETag field in the http response header changes, it indicates that the visualization application has been updated, and an updated version exists. At this time, the browser may acquire the updated version of the visualization application from the server and run the updated version of the visualization application. When the value of the ETag field in the http response header is unchanged, the visualization application is not updated, and no updated version exists. At this time, the browser acquires the visualization application from the cache resource and runs the visualization application.
In this embodiment, the terminal receives the response information returned by the server through the browser, identifies whether the visual application has an updated version according to the response information, and decides whether to obtain the visual application of the updated version from the server or the visual application from the cache resource according to the response information, so that when the new version is released, the visual application of the new version can be automatically obtained without manually pulling the visual application of the new version, and automation of release of the new version application is realized.
In one embodiment, rendering the vehicle-mounted data through the browser and displaying the rendered vehicle-mounted image on the visual application comprises converting the vehicle-mounted data into corresponding index data through the visual application, rendering the index data through the browser and displaying the vehicle-mounted image on the visual application.
After the terminal obtains the vehicle-mounted data returned by the server through the visualization application, the vehicle-mounted data can be converted into corresponding index data through the visualization application. The vehicle-mounted data may be vehicle-mounted data within a preset period of time. The server returns the vehicle-mounted data to the visualization application in the form of character strings, and the visualization application converts the received character strings into index data, namely objects. The index data may include indices of travel speed, travel mileage, position coordinates, and the like. The browser renders the index data, namely pages are rendered, and a vehicle-mounted image is generated, wherein the vehicle-mounted image is a continuous multi-frame vehicle-mounted image with a time sequence. Each frame is a static picture, the terminal displays the multi-frame vehicle-mounted image through the visual application, and the multi-frame vehicle-mounted image is formed into an animation. Page rendering refers to a process of parsing html (hyper text markup language ) through rules defined by CSS (CASCADING STYLE SHEETS, cascading style sheet) to achieve page drawing.
In the embodiment, the terminal converts the vehicle-mounted data into the corresponding index data through the visual application, which is favorable for the browser to accurately and rapidly render the vehicle-mounted data, so that the index data is rendered through the browser to obtain the vehicle-mounted image. The vehicle-mounted image is obtained through browser rendering analysis, so that the obtained vehicle-mounted image is more complete, and the accuracy of vehicle-mounted image display is improved.
In one embodiment, the terminal may calculate and combine the index data through a scripting language engine in the browser, and render to obtain the vehicle-mounted image. Specifically, the corresponding position of the index data is calculated through a script language engine in the browser, so that the index data is combined to obtain a complete vehicle-mounted image, and the complete vehicle-mounted image is displayed on the visualization application. The scripting language engine may be a javascript engine. The vehicle-mounted image obtained by calculation and combination through the scripting language engine is more complete, and the accuracy of vehicle-mounted image display is effectively improved.
In one embodiment, generating the data acquisition request according to the data identifier by the visualization application comprises assembling the data identifier by the visualization application according to a preset protocol to obtain assembled data, packaging the assembled data by the visualization application to obtain packaged data, and generating the data acquisition request according to the packaged data by the visualization application.

And assembling the data identifier according to a preset protocol through a visual application to obtain assembled data. The assembled data may include data identification, header files, interface identification, status data of the terminal, etc. The header file may be a carrier file containing the function, the data interface declaration. And the terminal encapsulates the assembled data into the object through the visual application, so as to obtain the encapsulated data. An object may be a variable having a type of class. A class may be a blueprint for creating objects, and may be a software template for methods and variables in a particular type of object. The class may encapsulate the assembled data and operations on the assembled data.
The terminal generates a data acquisition request according to the packaged data, and can send the data acquisition request to the server according to a preset protocol. The server is preconfigured with a preset protocol. After the server receives the data acquisition request, a preset protocol is called to analyze the data acquisition request, so as to obtain a data identifier, a header file, an interface identifier, state data of the terminal and the like. And the server packages the analyzed data into a request object, calls an interface corresponding to the interface identifier according to the request object, and obtains vehicle-mounted data corresponding to the data identifier from the cloud through the interface. And the server sends the vehicle-mounted data to the visualization application by using the response object.
In this embodiment, the terminal assembles and encapsulates the data identifier according to the preset protocol through the visualization application, so as to generate the data acquisition request, so that the data identifier can be hidden, the data identifier and the corresponding code are prevented from being randomly accessed by the code defined by the external class, and the safety of vehicle-mounted data acquisition is improved.
