The terminal devices 101, 102 and 103 may be various electronic devices installed with an electronic map and having video recording and information recording function, including but not limited to, smart phones, tablet computers, laptop computers and desktop computers.
The server 105 may be a server performing data processing on the driving route, the driving record video and the record file sent from the terminal devices 101, 102 and 103. The server 105 may read event information from the record file, acquire driving information from the driving record video, and acquire a pending prompt information provided by the electronic map and corresponding to the event information and the driving route; and finally, establish an information querying table containing the event information, the driving information and the pending prompt information.

With further reference to
Step 201, acquiring a driving route, a driving record video, and a record file.
In this embodiment, the electronic device (e.g., the server 105 as shown in
The user carries the terminal devices 101, 102, 103 while driving. Through the electronic map installed on the terminal devices 101, 102, and 103, the user may not only acquire the route information, but also acquire the prompt information of the real-time road information provided by the electronic map. Alternatively, the prompt information may include traffic congestion information, traffic light information, road construction information, and the like. The terminal devices 101, 102, and 103 may also record the route information on the electronic map corresponding to the actual driving route, and obtain the driving route. During the actual driving course, the user may also record the video information during the actual driving course through the cameras on the terminal devices 101, 102, and 103, and obtain the driving record video corresponding to the driving route. When the user finds that the prompt information of the real-time road information provided by the electronic map is different from the actual road information, the corresponding event information may be recorded on the terminal device 101, 102, and 103. The event information may include time information, location information, and event content. The time information is used to record the time when the event occurs; the location information is used to record the location where the event occurs; and the event content is used to record the information of that the prompt information of the electronic map is different from the actual road condition. Since the road information is changing in real time, the user may send the corresponding driving route, the driving record video and the record file to the server 105 after recording a piece of event information, facilitating the timely correction of the prompt information of the electronic map. Alternatively, the user may also set the permission to acquire videos for the electronic map and provide a window for editing the record file. When the user finishes editing the record file, the driving route, the driving record video, and the record file are automatically sent to the server 105.
Step 202, reading the event information in the record file, acquiring driving information corresponding to the event information from the driving record video, and acquiring pending prompt information provided by the electronic map corresponding to the event information and the driving route.
In order to timely correct the prompt information on the electronic map, the server 105 first reads the event information in the record file after receiving the driving route, the driving record video, and the record file. The event information records the event information of that the prompt information provided by the electronic map is different from the actual driving course, that is, the prompt information provided by the electronic map may be in error. The event information includes time information, location information, and event content, and through the event information the prompt information that may be in error can be quickly and accurately located. In order to verify the authenticity of the event information, the driving information corresponding to the event information may be acquired from the driving record video. The driving information may include a driving image and/or a video segment. After that, the prompt information provided by the electronic map and corresponding to the event information and the driving route is took as the pending prompt information. At this time, the obtained event information, driving information and pending prompt information provide necessary information support for modifying the prompt information.
In some alternative implementations of the present embodiment, the acquiring driving information corresponding to the event information from the driving record video may include the following steps:
In the first step, the time information is extracted from the event information, and a time stamp corresponding to the time information is searched for in the driving record video.
The event information is recorded when the user finds that the prompt information of the real-time road information provided by the electronic map is different from the actual road information. That is, the time information contained in the event information is the time when the prompt information in an error. To this end, the time information may be extracted from the event information, and a corresponding time stamp (for example, xx o'clock xx minutes xx seconds) in the driving record video may be found based on the time information. The time stamp is used to mark the recording time of the image in the driving record video.
In the second step, the event content is extracted from the event information, and the driving information is acquired at the time stamp according to the event category of the event content.
The event content records the information of that the prompt information provided by the electronic map is different from the actual road information. According to the information content recorded in the event content, the event content may be divided into multiple event categories. The event category includes at least one of the following: navigation error information, traffic congestion error information, or road construction error information. For different event categories, the driving information that needs to be acquired may be different, depending on actual needs.
In some alternative implementations of the present embodiment, the acquiring, at the time stamp, the driving information according to the event category of the event content may include: acquiring a video corresponding to a first set time period preceding the time stamp and/or a video corresponding to a second set time period succeeding the time stamp in the driving record video, when the event category is the navigation error information category, in the negative, acquiring an image corresponding to the time stamp in the driving record video.
As may be seen from the above description, for different event categories, the driving information that needs to be acquired may be different. In this embodiment, when the event category is the navigation error information category, a video corresponding to a first set time period preceding the time stamp and/or a video corresponding to a second set time period succeeding the time stamp in the driving record video may be acquired, to correct the navigation information through the information recorded in the video. For example, a time stamp (for example, 13:25:00) may be used as the starting time, and a video of the first set time period (for example, 1 minute) may be selected forward (a video between 13:24:00 and 13:25:00) as the driving information, or a video of the second set time period (for example, 2 minutes) may be selected backward (a video between 13:25:00 and 13:27:00) as the driving information. The lengths of the first time period and the second time period may be set as required. For other event categories that can be determined without videos, the images corresponding to the time stamps may be directly acquired.
Acquiring a corresponding video or image according to the event category may be determined as required. In some alternative implementations, the corresponding video and image may be set to be acquired at the same time according to a certain event category.
In some alternative implementations of the present embodiment, the acquiring pending prompt information provided by the electronic map and corresponding to the event information and the driving route may include the following steps:
In the first step, the location information is extracted from the event information, and a location stamp corresponding to the location information is set on the driving route.
The event information may also include location information, which is used to record the location of the user when the event occurs. At the same time, the same location, different driving directions or different driving routes may also have different road conditions. Therefore, when searching for the prompt information, the actual driving route should also be considered, and further the location stamp corresponding to the location information is set on the driving route.
In the second step, the pending prompt information provided by the electronic map and corresponding to the location stamp and the time information is queried.
Due to the large amount of the prompt information provided by the electronic map, the prompt information may be queried according to time information or location information. At the same time, the pending prompt information corresponding to the event information can be determined according to the location stamp and the time information.
Step 203, establishing a corresponding relationship between the event information, the driving information, and the pending prompt information, and establishing an information query table based on the corresponding relationship.
After the server 105 obtains the event information, the driving information, and the pending prompt information, the event information, the driving information, and the pending prompt information may be respectively saved in different information storage sections (or folders) on the server 105. Then, the corresponding relationship between the event information, the driving information, and the pending prompt information may be established by establishing a shortcut link or the like, to facilitate the mutual retrieval between information. In order to facilitate the verification and modification to the information, an information query table may also be established based on the corresponding relationship. An optional approach is: first generating a blank table, and then setting, in the table, an event information display window, a driving information display window and a pending prompt information display window for the event information, the driving information and the pending prompt information respectively; then, the event information (or the shortcut of the corresponding event information) is loaded into the event information display window. The event information display window may include a time information column, a location information column, and an event content column to display the time information, the location information, and the event content included in the event information in the time information column, the location information column, and the event content column, respectively. The driving information includes both video and image formats. For convenient viewing of videos or images, a window size adjustment option may also be set on the driving information display window. The pending prompt information display window is used to display the pending prompt information found by the server 105. In the information query table, when a certain piece of event information is selected, the driving information or the pending prompt information corresponding to the event information is simultaneously displayed. Similarly, when a certain piece of driving information is selected, the event information and the pending prompt information corresponding to the driving information are also displayed at the same time. In this way, the process of manually searching for information by a technician is avoided, the efficiency of information query, information verification and information modification is greatly improved, and the accuracy of the prompt information provided by the electronic map is improved.
