The broadcasting service that speed plays.
Further, the moving operation information is the operation behavior actively or passively according to driver to vehicle drive
The information recorded comprising bring to a halt, racing is at least one of, driving assistance system intervention work.
The beneficial effects of the present invention are: can be user, such as traffic police and accident side, driving recording be played in viewing
When, the key position of record video is quickly navigated to, the information of driving recording can be facilitated further to be applied.
Detailed description of the invention
Fig. 1 shows the basic composition block diagram of this system;
Fig. 2 shows the flow charts for the method that this system is implemented;
Fig. 3 shows the flow chart of the another method of this system implementation.
Specific embodiment
With reference to the accompanying drawings, the function of this system is described in detail.
As shown in Figure 1, system includes:
Communication unit 1 is used to establish and keep and driving recording picture pick-up device, and the data connection with vehicle CAN bus;
For example, establishing data connection by wired or wireless (vehicle-mounted wifi, bluetooth etc.) and train movement recording equipment, connect by OBD data
The CAN bus of mouth and vehicle establishes data connection.There is no limit for specific connection type by the present invention.It needs to protect after establishing connection
The connection is held, to obtain related data in real time in the implementation process of method.
Data cell 2 is used to obtain or receive the driving recording video from driving recording picture pick-up device, and comes
From the moving operation information of vehicle CAN bus;In entire driving conditions, automobile data recorder can continue to carry out video record, In
In this method, driving recording video includes image and and continuously corresponding playing time real-time with image.The moving operation
Data are the information recorded according to operation behavior actively or passively of the driver to vehicle drive, including bring to a halt,
Racing is at least one of, driving assistance system intervention work, when driving, entire car controller/vehicle-mounted CAN bus meeting
The operation of (preferably real-time mode) record driver periodically or in real time, for example, when touching on the brake for driver is stepped on
More than one threshold value of stroke (needing stroke sensor as hardware supported) of plate then may determine that the driving behaviour to bring to a halt
Make or the ABS system of vehicle intervenes work, also may determine that and carrying out the operation brought to a halt for vehicle;
Processing unit 3 generates key point label according to the timestamp that the moving operation information carries, and by the time
The playing time for stabbing corresponding driving recording video is associated, and key point label is shown in driving recording video
Playing progress bar;
The timestamp carried according to the moving operation information generates key point label (label is slightly in advance in timestamp);Example
Such as, driver and this moment of 12:00:30 have carried out the moving operation brought to a halt, at the time of the operation of the operation occurs
12:00:30 is entrained timestamp, generates a key point label, particularly, key point label according to the timestamp
It should be slightly in advance in the timestamp, such as 12:00:29 at the time of corresponding;
The corresponding playing time of the timestamp is associated, key point label is shown in driving recording video
Playing progress bar;Illustratively, by the playing time of this timestamp of 12:00:30 and this driving recording video of 12:00:30
It is associated, the key point generated according to 12:00:30 this timestamp is marked be shown in the broadcasting of driving recording video into
It spends on item, that is, shows a mark point outstanding at the 12:00:29 of the playing progress bar in driving recording video, such as
One on progress bar is different from the coloured node of progress bar color.
First storage unit 4 is used to store the key point label of the driving recording video.
In one embodiment, the processing unit is also used to intercept driving recording video corresponding with the timestamp
Video-frequency band in the first duration of front and back of playing time.Correspondingly, being used to press the system also includes the second storage unit 5
It contracts and stores the video-frequency band, and the compression ratio of the video-frequency band is less than its in addition to the video-frequency band of driving recording video
His videograph, namely more crucial video-frequency band is stored using low compression ratio or the means of lossless compression.Also, the processing
Unit provides labeled as the driving recording video according to the key point and plays enhancing service, and the broadcasting enhances services package
Include: slow play or redirect broadcasting service for the video-frequency band, for driving recording video in addition to the video-frequency band
Other videographs quickly play or skip service at least one of.For example, choosing institute when user puts on a progress bar
State key point label when, call directly and play the key video sequence section of stored low compression ratio or lossless compression, so as to
Family shows the higher video image of clarity.
In another embodiment, the processing unit traverses the key point label of the driving recording video, inspection
The key point surveyed with the presence or absence of dense distribution marks group, namely whether there is in the second duration set at one is more than setting
Several key point labels;If it is present cancel the key point label of the centre of key point label group it is described play into
The display on item is spent, two key points of head and the tail for only retaining key point label group mark the display in the playing progress bar.
Under a kind of extreme moving operation, for example the racing of continuous several times backward and then stop by an emergency brake, walks using preceding method
It is rapid then can be left in the playing progress bar of driving recording video within the short several seconds it is multiple be located next to key points label, this
The video of point selection operation when watching to(for) user's later period be it is inconvenient, therefore, only retain head and the tail two key points label described
Display in playing progress bar.Correspondingly, system further includes third storage unit 6, it is used to store and the head and the tail two passes
Key point marks the video-frequency band between playing time corresponding to corresponding timestamp, it is contemplated that key point marks whole corresponding to group
A video-frequency band is all important, therefore, is directed to the broadcasting service that this section of video does not provide F.F. or quickly play.
One skilled in the art would recognize that without departing substantially from the spirit and scope of the invention as generally describing,
Various variations and/or modification can be carried out to invention shown in each specific embodiment.Therefore, in terms of all
For, embodiment here is considered as illustrative and and non-limiting.Equally, the present invention includes any feature
Combination, the combination of any feature especially in Patent right requirement, even if the combination of this feature or feature is not in patent
It is explicitely stated in claim or each embodiment here.
