In a first aspect, an embodiment of the present disclosure provides a navigation information display method, which is applied to an android platform end, and as shown in fig. 1, the method mainly includes:
101. and acquiring navigation information.
The navigation information comprises base map information and character information, the base map information is image data of a navigation map, and the character information is indication characters during navigation.
In the navigation process, the navigation information actually includes two contents, one is a text for indicating a specific driving condition of the current vehicle and an image for representing a position of the vehicle and a surrounding road, so in the embodiment of the present disclosure, when the navigation information display method is executed, the navigation information needs to be acquired first, specifically, the navigation information can be acquired from the current vehicle-mounted navigation system, and the navigation information includes text information indicating the text and base map information corresponding to image data representing the position and the surrounding of the vehicle.
102. And sending the base map information to a linux platform end of the locomotive system through a first channel, and sending the text information to the linux platform end of the locomotive system through a second transmission channel so that the linux platform end can display the base map information and the text information.
After the navigation information including the base map information and the text information is acquired, based on the characteristics of the text and the image in the transmission process, in the embodiment of the invention, two channels can be selected to respectively send the text information corresponding to the text and the base map information corresponding to the image, namely, a first channel is selected to send the base map information, and a second channel is selected to send the text information. Therefore, the first/second channel is selected to send the text and base map information, and the navigation information of the android platform end can be sent to the linux platform end, so that the function of cross-system transmission of the navigation information is realized.
Further, an embodiment of the present disclosure provides a navigation information display method, which is applied to a linux platform side, and as shown in fig. 2, the method mainly includes:
201. and after receiving the base map information and the text information, fusing the text information and the base map information to obtain navigation data.
Based on the foregoing embodiment, after the navigation information is transmitted by the first channel and the second channel according to the text information and the base map information, respectively, in order to restore the navigation information split into the text information and the base map information, after the text information and the base map information are received at the linux platform, the two information need to be fused according to the method in this step, so as to obtain the fused navigation data. The fusion mode may be performed according to any existing mode, for example, the base map information and the text information may be superimposed through a corresponding relationship between the base map information and the text information during transmission to obtain corresponding navigation data, and the navigation data may be combined based on a sequence of image frames to obtain a complete video stream, that is, the navigation data.
202. And displaying the navigation data at a preset display position.
After the text information and the base map information have been fused into the navigation data in step 201, the method according to the embodiment of the present disclosure is to solve the problem that the navigation information needs to be viewed back and forth between the display screen and the dashboard for displaying the driving situation of the vehicle when the vehicle is driving, therefore, in this step, the navigation data can be displayed at the preset position controlled by the linux platform, information such as driving parameters based on the vehicle is displayed in an instrument panel controlled by the linux platform end, thus, according to the method of this step, navigation data can also be displayed in the dashboard, so that during driving of the vehicle by the user, when navigation is needed, the processes of watching navigation information and watching vehicle driving parameters can be carried out by watching the instrument panel, so that the convenience of watching by a user in the navigation process is improved, and the driving safety is improved.
According to the navigation information display method provided by the disclosed embodiment, firstly, navigation information can be acquired at an android platform end, base map information is sent to a linux platform end of a locomotive system through a first channel, and text information is sent to the linux platform end of the locomotive system through a second transmission channel. Then, at the linux platform end, after receiving the base map information and the text information, fusing the text information and the base map information to obtain navigation data, displaying the navigation data at a preset display position, so that the navigation information can be respectively sent to the linux platform end from the android platform end through a first channel and a second channel according to the base map information and the text information, and the linux platform end fuses the base map information and the text information to obtain the navigation data again and displays the navigation data, thereby realizing the function of cross-system transmission of the navigation information from the android platform to the linux platform, transmitting the navigation information originally in the android system to the linux system for displaying, enabling the navigation information to be displayed in an instrument panel corresponding to the linux platform end, and solving the problem that a driver needs to watch back and forth from an instrument panel and an android display screen in the existing navigation information display process, the problem of inconvenient viewing is avoided, the simultaneous observation effect of the navigation information and the driving parameters can be realized only by viewing the instrument panel in the driving process, the potential safety hazard caused by the fact that a driver frequently views the display contents of the two systems at two positions respectively is solved, and the safety of vehicle driving is improved.
In a third aspect, according to the methods of the first and second aspects, another embodiment of the present disclosure further provides a navigation information display method, which can be applied to an android platform end and a linux platform end, and as a refinement and an extension of the methods of the two aspects, as shown in fig. 3 specifically, the navigation information display method includes:
301. and the android platform side acquires navigation information.
The navigation information comprises base map information and character information, the base map information is image data of a navigation map, and the character information is indication characters during navigation.
Specifically, in the process of acquiring the base map information and the text information in the navigation information from the navigation system or the navigation software, the execution mode may be performed as follows: for example, the acquisition of the base map information may be based on obtaining an original video stream from a provider of the navigation map (e.g., a Baidu map, a Gade map, etc.), wherein the video stream may be understood as a frame-based image combination. And for the acquisition of the text information, capturing the text output by the navigation map provider by operating a preset software or a preset service for monitoring the text information, and repackaging the captured text information according to a certain format.
302. And the android platform end sends the base map information to a linux platform end of the locomotive system through a first channel, and sends the text information to the linux platform end of the locomotive system through a second transmission channel.
During transmission, the transmission process is different according to different types selected by the transmission channel:
on one hand, when the first channel is a preset LVDS transmission channel and the second channel is a preset USB transmission channel, the execution process of this step may specifically be:
A. and projecting the video stream formed by the base map information into a linux platform end according to the preset screen division technology presentation through a preset LVDS transmission channel. Namely, the existing screen division technology presentation in the android system is directly projected to a small map display area of the instrument, and a specific channel can be transmitted by selecting an LVDS transmission channel. Lvds (low Voltage Differential signaling), i.e. low Voltage Differential signaling, is a novel technology that meets the requirements of current high-performance data transmission applications. It can also meet the needs of future applications because it can make the system supply voltage as low as 2V. The transmission channel base has 330mV of low voltage differential signal (250mV MIN and 450mV MAX) and fast transition time. This allows data transmission at high data rates from 100Mbps to over 1Gbps, with the advantage of high transmission rates. In addition, the low voltage swing can reduce power dissipation, and meanwhile, the low voltage swing has the advantage of differential transmission. Therefore, the base map information is transmitted by using LVDS, so that the lower time delay can be ensured during base map transmission, and meanwhile, the accuracy and stability during base map information transmission in the navigation information can be ensured based on the characteristics of low noise and low electromagnetic interference.
B. And sending the text information to a linux platform end through a USB transmission channel according to an ZMQ protocol.
The USB, namely a Universal Serial Bus (abbreviated as USB), is a Serial Bus standard for connecting a computer system and external equipment, and is also a technical specification of an input/output interface, and a USB transmission channel has the characteristics of wide use and good compatibility of transmitted contents, so that when character information is transmitted through the USB, the character information can be ensured to be transmitted after being processed when the character information needs to be filtered and processed, and the real-time property of data transmission is not influenced, thereby ensuring that the character information can be modified in real time based on the need during character transmission. In addition, the ZMQ-based protocol has the characteristic of topological multi-to-multipoint transmission, so that the text information is transmitted according to the AMQ protocol, the requirement of multipoint interaction during data transmission among a plurality of terminals can be met, and the convenience of text information transmission during transmission is improved.
On the other hand, when the first channel and the second channel are both preset USB transmission channels, the process executed in this step may specifically be: and sending the text information to a linux platform end through a preset USB transmission channel according to an ZMQ protocol. And sending the video stream formed by the base map information to a linux platform end through a preset USB transmission channel according to the RTSP. Among them, the RTSP Protocol (Real Time Streaming Protocol, RTST for short) is an application layer Protocol in the TCP/IP Protocol system, and defines how a one-to-many application program can effectively transmit multimedia data through an IP network. RTSP is a multimedia streaming protocol for controlling audio or video and allows simultaneous control of multiple streaming requests, and the network protocol used for transmission is not within the defined range, and time synchronization is not particularly emphasized, so network delay is relatively tolerable. Therefore, the base map information is transmitted based on the RTSP, and the problem of data abnormity caused by network delay in the transmission process of the base map information can be solved.
Further, in an actual application process, the navigation-based text may include many text that is not needed by the user, and then the text information may be filtered before being sent, specifically: and filtering the text information to obtain navigation text data, wherein the navigation text data comprises main content data required by navigation. In this way, when the method of the step is subsequently executed for transmission, the filtered navigation text data is sent to the linux platform end of the locomotive system through the second transmission channel.
303. And after the linux platform receives the base map information and the text information, fusing the text information and the base map information to obtain navigation data.
Wherein, the fusion process can be carried out according to the following modes: firstly, acquiring a time identifier of the navigation character data and a time identifier of the base map information; and then, according to the time identification, performing superposition operation on the navigation character data with the same time identification and the base map information to obtain the navigation data.
In addition, based on the foregoing steps, before the android platform transmits the text information, the text may be further filtered as described in step 302, and therefore, when the text is merged in this step, the merged text portion is the filtered text data.
In addition, in this step, before the fusion, the method further includes a transmission protocol based on the transmission of the base map information and the text information received by the linux, or a processing procedure during the transmission (where the processing procedure may include operations such as compression and packing of the two kinds of information), and before the fusion, the method further needs to select a corresponding processing mode to analyze the two kinds of information according to the difference between the transmission information and the processing procedure. For example, when the step 302 uses the USB channel to transmit the base map information according to the RTSP protocol, the step further includes a process of analyzing the base map information, so as to perform a fusion operation according to the analyzed base map information and the analyzed text information.
304. And setting a preset display position in the instrument panel at the linux platform end.
The method for displaying navigation information between systems according to the embodiment of the present disclosure may further include a process of setting the preset display position in the execution process, wherein in order to reduce the problem that a driver needs to observe the display screens of the navigation information and the driving parameters respectively when observing the navigation information and the driving parameters, the preset display position may be displayed in an instrument panel controlled by the linux platform end in this step.
It should be noted that the execution sequence of this step is exemplary, and is not limited herein, and this step may be executed in any step of the embodiment of the present disclosure during actual execution, for example, before step 303, that is, before navigation data is displayed, the step may be executed in advance, and also may be executed simultaneously when step 305 is executed, that is, when navigation data is displayed in the current dashboard, a display position currently required by a user is set simultaneously according to an instruction of the user.
305. And the linux platform end displays the navigation data at a preset display position.
After the base map information and the text information are fused, the navigation information is actually restored, and at this time, the navigation data can be displayed at the preset display position controlled by the linux platform end.
306. And when the navigation data is displayed in an instrument panel controlled by the linux platform end, the android platform end judges whether navigation information is displayed in a display screen controlled by the android platform end or not according to a preset instruction.
In an actual application process, after the preset display position of the linux platform end displays the navigation data, sometimes there may be a need for the android end to simultaneously display the information to be navigated, for example, the position of the dashboard is convenient for a driver to view, but is inconvenient for other people in the vehicle to view. In this case, the android platform end can determine according to a preset instruction to determine whether navigation information needs to be displayed at the same time.
Based on the determination result, when the determination result is yes, step 307 is executed; otherwise, step 308 is executed.
307. And the android platform end displays navigation information in a display screen controlled by the android platform end.
Therefore, other users in the vehicle can be ensured to know the navigation condition according to the navigation information displayed in the display screen controlled by the android platform terminal, and meanwhile, based on the position limitation in the instrument panel, under the condition that the actual content of the navigation information displayed by the users is limited, a driver can be ensured to confirm based on the navigation information of the android platform terminal when needing to know the detailed content of the navigation information, so that the navigation accuracy is improved.
308. And the android platform terminal displays the display content of the corresponding instruction according to the user instruction information.
When the fact that the user does not need to display the navigation information is determined, the fact that the driver knows the information required by navigation through navigation data in an instrument panel controlled by the linux platform is shown, meanwhile, the android platform end displays the display content of the corresponding instruction according to the user instruction information, it can be guaranteed that when other users in the vehicle have other functions to display, the navigation information does not occupy a display screen of the android platform end, the required content can be displayed according to the instructions of the users, and driving experience of other users in the vehicle is improved.
