Example one
Fig. 1 is a flowchart illustrating a method for processing a web map based on an on-vehicle smart device according to an embodiment of the present application.
Referring to fig. 1, in an embodiment of the present application, a method for processing a web map based on an on-vehicle smart device is provided, which includes:
step S110, detecting a specified event, and analyzing to obtain the map data to be displayed corresponding to the specified event.
In one embodiment, the specified event may be a map pan event or a map zoom event. The user views the electronic map in the webpage of the user end, and translates the electronic map or zooms the electronic map in the screen display range of the user end according to needs, so that the webpage displays the map content which the user needs to view. And the user side detects the designated event corresponding to the operation according to the operation of the user. In one embodiment, the user terminal may be an in-vehicle smart device.
It can be understood that different designated events correspond to different map data to be displayed, and the map data to be displayed obtained by analysis are also different. And analyzing and obtaining the map data to be displayed corresponding to the appointed event by detecting the appointed event.
And step S120, sending the map data to be displayed to a server, and calling the server to convert the map data to be displayed into a map picture to be displayed.
In one embodiment, a dynamic link library is generated in the server in advance; calling the dynamic link library, and obtaining a real-time rendering picture according to the map data to be displayed; and converting the real-time rendering picture into a map picture to be displayed.
Specifically, a Dynamic Link Library (DLL) is a way for microsoft corporation to implement the concept of shared function Library in microsoft operating systems. Updates can be more easily applied to individual modules using dynamically linked libraries without affecting other parts of the program. And after the user side sends the map data to be displayed after the designated event is analyzed to the server side, the user side calls a dynamic link library of the server side, obtains a real-time rendering picture at the server side through the dynamic link library, and converts the real-time rendering picture into a map picture to be displayed. In one embodiment, the server may be a server. The server stores all map data of the electronic map in advance.
Step S130, receiving the map picture to be displayed.
In one embodiment, the user terminal receives the map picture to be displayed in real time.

According to the design, on one hand, a WebGL platform does not need to be developed and built independently, and resource calling can be realized only by arranging the dynamic link library at the server side in advance, so that the development cost is saved, the development time is shortened, the later maintenance is facilitated, and the later maintenance efficiency is improved. On the other hand, the map data can be converted by using the existing server resources, the memory of the converted map picture is smaller than that of the map data, the receiving speed of the user side is increased, and the display efficiency of the user side is improved.
Example two
For further introduction of the method for processing a web map based on an on-vehicle intelligent device of the present application, referring to fig. 2, the method for processing a web map based on an on-vehicle intelligent device includes:
step S210, detecting a specified event on the HTML5 page, and analyzing the detected specified event by the HTML5 page to obtain corresponding map data to be displayed.
In the related art, HTML5 is a specification of core language HTML in the Web, and content viewed by a user when browsing a Web page by any means is originally in HTML format, and is converted into information recognizable by a browser through related art processing. By directly utilizing the HTML5 page to detect the specified event, the corresponding map data to be displayed can be obtained in real time, the program operation efficiency is improved, and the user waiting time is reduced.
In one embodiment, a specified event is detected, the specified event being a map panning event or a map zooming event; when the specified event is a map translation event, analyzing and obtaining corresponding position information when the map is translated; and when the specified event is a map zooming event, analyzing and obtaining the corresponding data level information when zooming the map.
It is to be appreciated that different scales can correspond to different data levels. And inquiring the data hierarchy corresponding to the scaling in the pre-stored data hierarchy according to the scaling input by the user. When the data hierarchy in the data hierarchy is sorted by arabic numbers, layer 1 may represent the top layer data, and layer 2, layer 3, and … … are arranged sequentially downward. When the scaling is a reduction scale, the lower the reduction scale, the higher the corresponding data level, for example, the data level corresponding to the reduction scale of 20% of the normal display size is higher than the data level corresponding to the reduction scale of 50% of the normal display size. When the zoom-in scale is an enlargement scale, the larger the enlargement scale, the lower the corresponding data level, for example, the data level corresponding to the enlargement scale of 2 times the normal display size is lower than the data level corresponding to the enlargement scale of 2 times the normal display size.
In one embodiment, the HTML5 page detects specified events in real time, and analyzes in real time to obtain the map data to be displayed corresponding to the specified events when each detected specified event occurs. It will be appreciated that for a map panning event, the data hierarchy of the electronic map within the screen display range does not change, but rather changes the geographical area of the same data hierarchy in the electronic map. When the specified event is a map translation event, the HTML5 page analyzes to obtain corresponding position information in the process of translating the map. In one embodiment, the location information may be latitude and longitude coordinates. Specifically, within the screen display range before panning the map, the HTML5 page may obtain the screen pixel coordinates of the initial position set by the user within the screen display range. The initial position may be the position where the user's finger first touches the electronic map in the screen. Of course, the initial position may be set by the user in other ways. After the user pans the map, the HTML5 page may obtain the screen pixel coordinates of the end position within the screen display range. The termination position may be a position of the user's finger after moving within the screen display range. Accordingly, between the initial position and the end position, i.e., the path that the user has traversed to pan the map, the path includes corresponding screen pixel coordinates. In the related art, the screen pixel coordinates may be converted into corresponding geographic coordinates, i.e., longitude and latitude coordinates. That is, for a map panning event, the HTML5 page may parse longitude and latitude coordinates corresponding to the initial position, the end position, and a path traversed between the initial position and the end position when the panning map is acquired, as the map data to be displayed.
Similarly, when the specified event is a map zooming event, the HTML5 page parses the corresponding data level information when obtaining the zoomed map. For a map zoom event, the data hierarchy of the electronic map within the screen display range changes. Prior to zooming the map, the HTML5 page may parse the corresponding data hierarchy before the map is zoomed. After zooming the map, the HTML5 page parse obtains the corresponding data level after the map is zoomed. During zooming, the HTML5 page parses the data hierarchy that gets the map traversed. That is, for a map zoom event, the HTML5 page may parse and acquire the data level before zooming, the data level traversed during zooming, and the data level when zooming is finally stopped, etc. as the map data to be displayed.
Step S220, the HTML5 page transmits the map data to be displayed to a Java layer, the Java layer sends the map data to be displayed to a server, and the server is called to convert the map data to be displayed into a map picture to be displayed.
In the related art, the Android operating system is a Linux-based operating system, and is mainly used for portable devices. Development of upper-layer applications in the Android system is generally completed based on Java. When the user side is a portable device, it can be understood that the operating system of the user side further includes a Java layer. Further, in one embodiment, the server may generate the dynamic link library in the server through C + + in advance. Wherein, C + + is a computer programming language, which is the inheritance of C language, and can be used for both the procedural programming of C language, the object-based programming characterized by abstract data types, and the object-oriented programming characterized by inheritance and polymorphism. By adopting C + + to establish the dynamic link library at the server, the system resources of the server are fully utilized, and no additional platform development and construction tasks need to be developed, so that the development efficiency can be improved. Further, the dynamic link library may contain a dynamic link library file with ". so" as an extension for Java layer calls.
After the HTML5 page transmits the map data to be displayed corresponding to the different specified events obtained by parsing in step S210 to the Java layer, in one embodiment, after the Java layer sends the map data to be displayed to the server, the Java layer calls the dynamic link library of the server to obtain a real-time rendering picture. That is, for example, for a map panning event, the real-time rendering screen is a screen of the entire panning process of the map from the initial position to the end position. Aiming at the map zooming event, the real-time rendering picture is a picture of the map traversing all levels of data levels before and after zooming. Further, the Java layer calls a dynamic link library of the server to obtain an OpenGL picture which is rendered in real time, each frame of map data to be displayed is obtained by utilizing an off-screen rendering technology of OpenGL, and then the OpenGL picture is coded into a map picture to be displayed in a specific format according to a related technology. OpenGL (Open Graphics Library, or "Open Graphics Library") is a cross-language, cross-platform application programming interface for rendering 2D, 3D vector Graphics. Further, in order to ensure that the map picture to be displayed in real time is displayed in the subsequent steps, the dynamic link library obtains an OpenGL picture which is rendered in real time according to a preset frame rate. Correspondingly, the OpenGL picture is converted into a map picture to be displayed according to a preset frame rate.
It can be understood that, for the map translation event, when the user translates the map in real time within the screen display range of the user terminal, the HTML5 page parses in real time to obtain all the map data to be displayed of the map during the translation process and transmits the map data to the Java layer. That is, the HTML5 page translates the map to the location information experienced during the process
In step S230, the Java layer receives the map picture to be displayed sent by the server.
Further, when a map translation event or a map zooming event is detected, the display content of the electronic map changes in real time within the screen display range. In order to enable the screen of the user side to display the changing content of the electronic map in real time, in one embodiment, the Java layer refreshes and receives the map picture to be displayed according to a preset frame rate. Further, according to different specified events, the occupied resources are different in size, and the sizes of the picture memories to be displayed are different, in one embodiment, the corresponding preset frame rate is set according to the system resources occupied by the specified events. Or, in other embodiments, the corresponding preset frame rate is set according to the changed data size of the electronic map. When the map data change is large, the preset frame rate can be set to be 30 frames/second; when the map data change is small, the preset frame rate may be set to be less than 30 frames/second. By setting the preset frame rate, the Java layer can refresh and receive the map picture to be displayed according to the preset frame rate.
And according to the preset frame rate, the Java layer refreshes and receives the map picture to be displayed sent by the server side in real time so as to ensure that the user side subsequently displays the real-time electronic map picture.
In step S240, the Java layer transmits the map picture to be displayed to the HTML5 page, and displays the map picture to be displayed on the HTML5 page.
It can be understood that, as the Java layer refreshes the map picture to be displayed sent by the receiving server in real time, the Java layer transmits the map picture to be displayed to the HTML5 page in real time. In one embodiment, the HTML5 page displays the map picture to be displayed according to a preset frame rate, so that the user end can display the real-time rendered and converted electronic map picture in time.
In the above embodiment, when the user views the electronic map on the HTML5 page at the user end, a specified event such as panning or zooming is performed on the electronic map within the display range of the screen. And when the HTML5 page detects a corresponding specified event, analyzing the specified event to obtain corresponding map data to be displayed. Then the HTML5 page transmits the parsed map data to be displayed to a Java layer at the user end. And the Java layer sends the map data to be displayed to a remote server, wherein the server generates a dynamic link library by using C + + in advance. After the server receives the map database to be displayed, the Java layer calls a remote dynamic link library to render the map data to be displayed into an OpenGL picture in real time according to a preset frame rate. Meanwhile, the Java layer further calls a dynamic link library to convert each OpenGL picture into a map picture to be displayed in a specific format in a real-time coding manner. And the server transmits the converted map picture to be displayed to the Java layer. And the Java layer refreshes and receives the map picture to be displayed in real time according to the preset frame rate, and transmits the map picture to be displayed to the HTML5 page for real-time display, so that a user can check the real-time change of the electronic map within the screen display range.
In summary, in the method for processing the webpage map based on the vehicle-mounted intelligent device in the embodiment of the application, the resources of the remote server can be directly called according to the HTML5 page and the Java layer existing at the user side, and the map data to be displayed is converted into the map picture to be displayed with a smaller memory. On one hand, the design ensures that the whole framework is simple and easy to develop, is convenient to maintain, and reduces the technical difficulty and cost; on the other hand, the electronic map is refreshed and displayed in real time in a picture mode, system loads of a user side and a server side are reduced, display efficiency is high, and experience instant experience of a user for checking the map is improved.
Corresponding to the embodiment of the application function implementation method, the application also provides a processing device of the webpage map, the electronic equipment and a corresponding embodiment.
