The embodiment of the disclosure provides a display method of a vehicle-mounted data image, which comprises the following steps: acquiring a vehicle-mounted data source comprising a plurality of different vehicle-mounted data; and rendering the plurality of vehicle-mounted data by using the same map rendering engine to obtain vehicle-mounted data images corresponding to the vehicle-mounted data, and transmitting the vehicle-mounted data images to corresponding display equipment for display. That is, in the method of the embodiment of the present disclosure, one map rendering engine may perform rendering processing on various kinds of in-vehicle data.
The vehicle-mounted data image in the embodiment of the disclosure can include, but is not limited to, an instrument map image such as a vehicle speed and a mileage displayed on an instrument panel in a vehicle, and a vehicle map image and a front page map card image on the vehicle, wherein the vehicle map and the front page map image are different applications on the vehicle. In this way, the instrument map image rendered by the map rendering engine is transmitted to the instrument panel for display; the map rendering engine renders to obtain a map image of the vehicle and a map card image of the front page, and the map image and the map card image are transmitted to the vehicle for display.
Wherein, for the method of the embodiment of the disclosure, the execution subject is a display system of the vehicle-mounted data image, and the system can be integrated in a vehicle; of course, the system may also be a stand-alone structure.
In the method for displaying an in-vehicle data image according to the embodiment of the present disclosure, the in-vehicle data image includes: the instrument map image, the home map card image, and the car machine map image are described as examples.
Fig. 1 is a flowchart of a display method of an in-vehicle data image according to an embodiment of the present disclosure.
In a first aspect, an embodiment of the present disclosure provides a method for displaying an on-vehicle data image, referring to fig. 1, the method specifically includes the following steps:
s1, acquiring a vehicle-mounted data source, wherein the vehicle-mounted data source comprises various vehicle-mounted data, and specifically comprises: instrument map data, home map card data, and car map data.
Specifically, the speed acquisition module acquires the speed information of the vehicle in real time, and the calculation module can calculate the mileage of the vehicle according to the speed information of the vehicle; the GPS positioning module can acquire the position information of the vehicle; the information is transmitted to a display system of the vehicle-mounted data image as a vehicle-mounted data source.
And S2, rendering the instrument map data, the home page map card data and the car machine map data through the same map engine to obtain an instrument map image corresponding to the instrument map data, a home page map card image corresponding to the home page map card data and a car machine map image corresponding to the car machine map data image.
It should be noted that, step S2 requires support of multiple map rendering engines, that is, one map rendering engine can perform rendering processing on multiple map data at the same time. Therefore, the display system of the in-vehicle data image starts the map rendering engine before performing this step; the display system of the vehicle-mounted data image starts up and runs the map rendering engine, and the supporting main mode of rendering map content is as follows: the starting logic mode of the map application of the vehicle-mounted machine is modified, so that the initialization of a map rendering engine can be completed without an interface for explicitly starting the map application, and map content is rendered to target equipment; when the display system of the vehicle-mounted data image is started, the multi-screen map service of the vehicle-mounted data image is actively bound, namely, background initialization of the application can be triggered, monitoring of the virtual display equipment is started, and at the moment, support of outputting map content to the third-party display equipment can be completed.
In step S2, the display system of the vehicle-mounted data image outputs the instrument map data, the home page map card data and the vehicle map data acquired in step S1 to a map rendering engine, and the map rendering engine provides rendering environments for the instrument map data, the home page map card data and the vehicle map data respectively, and performs rendering processing on the instrument map data, the home page map card data and the vehicle map data in different rendering environments, so as to obtain an instrument map image, a home page map card image and a vehicle map image.
And S3, transmitting the instrument map image, the home page map card image and the car machine map image to corresponding display equipment for display.
In step S3, the display system of the vehicle-mounted data image transmits the meter map image rendered in step S2 to the dashboard for display, and transmits the home map card image and the vehicle map image to the vehicle for display.
Because the display method of the vehicle-mounted data image provided by the embodiment of the disclosure can render different vehicle-mounted data through the same map rendering engine, the vehicle-mounted integration level can be greatly improved, and the vehicle-mounted data image rendering step can be simplified, so that the display method of the vehicle-mounted data image of the embodiment of the disclosure is easier to realize.
Fig. 2 is a specific flowchart of the vehicle-mounted data including the meter map data in step S2 of the embodiment of the present disclosure.
Referring to fig. 2, in some embodiments step S2 includes: rendering the instrument map data through a map engine to obtain an instrument map image; the method specifically comprises the following steps:
s21, creating a first virtual display device.
Specifically, in order to be able to render the meter map image, the display system of the vehicle-mounted data image needs to provide a rendering environment for the map rendering engine, and at this time, the dashboard needs to be abstracted to be the first virtual display device, so in step S21, the display system of the vehicle-mounted data image creates the first virtual display device.
FIG. 3 is a specific flowchart of step S21 in an embodiment of the present disclosure; referring to fig. 3, in some embodiments, step S21 may specifically include the following steps:
s211, acquiring a first Surface through a media code decoder.
Specifically, the display system of the vehicle-mounted data image acquires one Surface, i.e., a first Surface, through a media code decoder (MediaCodec). The MediaCodec class may be used, among other things, to use some basic multimedia codec (audio video codec component) that is part of the Android-based multimedia support infrastructure, typically used with MediaExtractor, mediaSync, mediaMuxer, mediaCrypto, mediaDrm, image, surface, and AudioTrack. A codec may process input data to produce output data, and the codec uses a set of input and output buffers to process data asynchronously. The user can create an empty input buffer, fill the data and send it to the codec for processing. The codec uses the input data to convert and then outputs to an empty output buffer. And finally, the user acquires the data of the output buffer area, consumes the data in the output buffer area and releases the data back to the coder-decoder. The codec repeats these operations if there is more data to continue processing.
S212, calling a display manager to create a first virtual display device through a prestored first virtual display creation method by taking the first Surface as a parameter.
Specifically, the display system of the vehicle-mounted data image may call the display manager (DisplayManager) to create the first virtual display device by using the first Surface acquired in step S211 as a parameter through a pre-stored method of creating a virtual display (createvualdisplay).
The DisplayManager is used for providing an external interface so as to realize mirror image display of different displays; createVirtualDisplay refers to a method of creating a virtual display.
And S22, using the first virtual equipment as a rendering environment, and rendering the instrument map data through a map rendering engine to obtain a virtual instrument map image.
Specifically, in the display system of the vehicle-mounted data image in step S22, the first virtual display device created in step S21 is used as a rendering environment, and map data is rendered in the environment by the map rendering engine to obtain a virtual meter map image, it should be understood that the virtual meter map image obtained at this time is adapted to the first virtual display device, and the display system of the vehicle-mounted data image is integrated in the vehicle, so that if the virtual meter map image is displayed on the dashboard, the video format of the virtual meter map image needs to be encoded, so that the meter map image can be displayed on the dashboard, that is, step S23 described below is performed.
S23, coding the virtual instrument map image to obtain the instrument map image.
Specifically, in step S23, the display system of the vehicle-mounted data image encodes the virtual instrument map image into the h.264 video format, and specifically, may call the corresponding interface of the video stream encoding shape of the media code decoder (MediaCodec).
Fig. 4 is a specific flowchart of the vehicle-mounted data including the home map card data in step S2 in the embodiment of the present disclosure.
Referring to fig. 4, in some embodiments, step S2 includes: rendering the home page map card data through a map engine to obtain a home page map card image, wherein the method specifically comprises the following steps:
s24, creating a second virtual display device.
Specifically, in order to render the top page map card image, the display system of the vehicle-mounted data image needs to provide a rendering environment for the map rendering engine, and at this time, the top page map card application needs to be abstracted into the second virtual display device.
Fig. 5 is a specific flowchart of step S24 in the embodiment of the present disclosure.
Referring to fig. 5, in some embodiments, step S24 may specifically include the steps of:
s241, acquiring a surface view provided by the home map card application.
Specifically, the home map card application is an application on the vehicle, so that the home map card application only needs to provide a surface view as a display window. Therefore, in step S241, the display system of the in-vehicle data image needs to acquire the surface view provided by the home map card application.
The surface view is an insert for drawing an image, and is provided with two interfaces, namely a surface holder and a Runneable; used in the embodiments of the present disclosure is a surface holder interface in which the methods to be implemented correspond to the lifecycle of surface view, i.e., create, change, and destroy, respectively.
S242, acquiring a second Surface through a Surface holder of the Surface view.
Specifically, in step S242, the display system of the vehicle-mounted data image acquires a Surface, that is, a second Surface, through the Surface holder of the Surface view acquired in step S242.
S243, calling the display manager to create a second virtual display device through a pre-stored second virtual display creation method by taking the second Surface as a parameter.
Specifically, the display system of the vehicle-mounted data image may call the display manager (DisplayManager) to create the first virtual display device by using the second Surface acquired in step S242 as a parameter through a second method of creating virtual display stored in advance.
And S25, using the second virtual display device as a rendering environment, and rendering the home page map card data through a map rendering engine to obtain a home page map card image.
Specifically, in the display system of the vehicle-mounted data image in step S25, the second virtual display device created in step S24 is used as a rendering environment, and map data is rendered in the rendering environment by a map rendering engine, so as to obtain a top page map card image. Here, since the home map card application is one application in the car machine, the video format of the home map card image obtained in step S25 is adapted to the car machine, so that conversion of the video format is not required.
Fig. 6 is a specific flowchart of the vehicle-mounted data including the vehicle-mounted map data in step S2 of the embodiment of the present disclosure.
Referring to fig. 6, in some embodiments, step S2 includes:
and S26, acquiring vehicle map data, and rendering the vehicle map data through a map rendering engine to obtain a vehicle map image.
Specifically, in step S26, the Display system of the vehicle-mounted data image may use Display for creation of the presentation when the Display content/data change of public is monitored, and may add and Display mapghlsourfaceview when the presentation is created and displayed. Wherein, mapGL is a new technology added for Google map by combining the latest WebGL technology. It allows the user to actually view the scene in a three D mode in the browser, rather than just some planar images taken at a particular angle as was previously seen. That is, the display system of the vehicle-mounted data image may directly render the acquired vehicle map data by the map rendering engine to obtain the vehicle map image. Because the display system of the vehicle-mounted data image is integrated in the vehicle, the video format of the vehicle map image is matched with the vehicle, so that the vehicle map image can be directly displayed on the vehicle.
It should be noted that, the step S2 may include the steps S21-S26, and the rendering steps of steps S21-S23, the rendering steps of steps S24-S25, and the rendering steps of step S26 in the step S2 are performed in different rendering environments, but the three rendering processes are performed simultaneously and not sequentially.
