Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below in conjunction with attached drawing to reality
Example is applied to be briefly described：
The locomotive driving real time information source used in the present embodiment is LKJ programs, which utilizes Socket mechanism to the present invention
System send real-time driving information.
Fig. 1 is in mileage M=1492035 using LKJ by initial position fix.
Fig. 2 is the part of whole record form, wherein chosen entry is the whole record consistent with LKJ initial positions
Initial position, because the mileage of the two is completely the same, therefore need not adjust the value of M.
Fig. 3 is the manually definite corresponding two field picture in video initial position, corresponding frame number 16253, and video is broadcast just at this time
Put to the position by the Miluo River exit signal, mileage valuation m=M+0=1492035 of the frame, particularly point out, the video is in itself
Frame per second r=50.
Fig. 4 is the transport condition that operator carries out LKJ displayings after acceleration operation, it can be seen that mileage M=1492022 at this time
（Accurate is M=1492021.66）, speed V=24km/h=6.67m/s, the real time information is using as the locomotive driving information of renewal
For subsequently calculating, particularly point out mileage numerical value here and reduce relative to original state, this is determined by the travel direction of locomotive
, foregoing calculation is not influenced, in addition, it is notable for result of calculation, here deliberately machine is updated after the i=2s of selection interval
Car driving information, corresponds to video frame refreshing frequency w=0.5, w=25 is generally made in practical application.
Fig. 5 is the part of whole record form, chosen entry be after Fig. 4 updates transport condition, it is current corresponding
Whole process record entry, as the step of preceding solution（6）, the entry be in whole record first mileage be located at M=
1492021.66 afterwards（It is less than M=1492021.66）Record, the speed of locomotive is 20km/h=5.56m/s in the record,
It is taken as that in current video locomotive speed v=5.56.
Step in technical solution can be carried out at this time（7）-（10）Calculating, according to step（7）Play frame rate is roughly calculated
R0=V/vr=6.67/5.56 × 50=60, according to step（8）Update mileage error e=1492035-1492021.66=13.34, note
It is because refreshing frequency w is too low that error here of anticipating, which reaches 13.34 meters, is not in this larger error amount in practice.
According to step 9 to R0It is modified, in view of e>0, it is contemplated that the direction of locomotive driving is the direction that mileage reduces, this
When video playing lag behind locomotive driving, therefore suitably increase play frame rate, in the present embodiment, the amendment ratio of fixed frame per second is
R010%, i.e. R=(1 ± 10%) × R0, therefore R=(1+10%) × R herein0=66。
According to step 10, s=R/w=66/0.5=132, therefore should decoding video, and every 132 frame shows a frame frame by frame, then
The frame number of next frame is initial frame number+132=16253+132=16385.
Fig. 6 illustrates the two field picture corresponding to frame number 16385.
Next according to step（11）, obtain the frame（That is frame number 16385）Corresponding mileage valuation, with reference to travel direction,
M can be obtained1=m1=m0+ivr/R0=1492035-2 × 6.67 × 66/60=1492035-14.67=1492020.33, it is contemplated that
In the case where locomotive driving real time information source speed is constant, the mileage updated next time will be M=1492021.66-2 × 6.67
=1492008.32, e=1492020.33-1492008.32=12.01 can be obtained by calculating mileage error again at this time, compare the e of last time
=13.34 errors are decreased, present the modified effect of play frame rate.
Repeating the above process constantly can obtain and show next two field picture, and obtains the video consistent with driving information and broadcast
Put effect.
Fig. 7 is FB(flow block) of the present invention.
Embodiment
（1）Data acquisition：Controlled video is during locomotive driving in the present invention, is clapped using video camera in front
The video taken the photograph, in order to know the transport condition of each moment locomotive of video substantially, the present invention uses derived complete after locomotive driving
Cheng Jilu, whole process record include a plurality of record of locomotive driving state, at the time of every record is all recorded comprising generation, real-time row
The information such as speed, real-time mileage are sailed, shooting video and the whole record system of export once travel for the same of same locomotive.
In addition, the present invention needs to be used in combination with certain locomotive driving real time information source, and here, locomotive driving real time information
Source is usually certain needs the simulation locomotive control that manipulates by start-up, and system real-time exhibition simulation locomotive is current
Transport condition, and can be by the transport condition of operation change simulation locomotive by start-up, locomotive driving real time information source leads to
Cross certain message passing mechanism（Such as Socket）Necessary driving information is sent to the video playing control system of the present invention,
These necessary driving informations include：
The mileage that the current travel speed of locomotive and locomotive are presently in.
（2）Align initial position：The benchmark of control is played, it is necessary to video, whole record and motor supply shop as subsequent video
The initial position for sailing this three of real time information source is alignment.Specific alignment procedure is as follows：
（21）Initial position is selected to locomotive driving real time information source, which is arbitrary, but for the ease of in video
It is middle to choose corresponding initial position, the general position for recommending to select some markers to occur（Such as semaphore, speed(-)limit sign）.If
The initial position is located at the scope that video is covered, then system can efficiently control broadcasting and the machine of video in follow-up link
Car traveling real time information source is consistent；Otherwise, locomotive driving real time information source given information is at this time by beyond the scope of video
The broadcasting united without video.
（22）According to the corresponding mileage M of locomotive driving real time information source initial position, each bar record in whole record is compareed
Mileage information, find it is corresponding that record.If there is no the completely the same record of mileage, mileage is selected to be located at locomotive
First initial position recorded as whole process record after the initial mileage in real time information source is travelled, at the same locomotive driving is real
When information source initial position be revised as this and record corresponding mileage.
（23）According to the initial position of whole process record, with reference to the manually identification to the marker in video, obtain and whole process
The initial position corresponding video moment is recorded, which is the initial position of video.
Particularly point out, the mileage scope that whole process record and video are covered is limited, which is known as effective range.When
For the initial position in locomotive driving real time information source not when within effective range, system does not perform follow-up calculating, also without regarding
The broadcasting of frequency.
（3）The mileage error e of alignment is initialized as 0：The alignment procedure of step 2 determines by artificial interpretation, therefore visual right
Neat mileage error e=0.Therefore, the corresponding mileage valuation of initial video frame is m=M+e=M.Follow-up video control played
The error will be updated in journey, and for adjusting the broadcasting speed of video to ensure that the high accuracy of critical importance is alignd.
（4）Show initial video frame：Decoding video, and according to step（2）Definite video initial position, shows initial bit
Corresponding video frame is put, the starting point as video playing；
Next, according to the frequency w of video playing control system refreshing video frame, needed more every one section of fixed time interval
The display of new primary video frame, and then the effect of video playing.Such as refreshing frequency w=25, time interval i=
40ms.Follow-up core operation, which is converted into determine to refresh next time, needs to show which frame in video, and when required
Between be spaced after show this frame.Retouched below exemplified by determining to need video frame to be shown next time after showing initial frame
State.
（5）Update locomotive driving information：It is real from locomotive driving first when calculating needs video frame to be shown next time
When information source obtain newest driving information, to keep playing the uniformity with driving information, step（1）It has already been indicated that this
A little information include the current speed V of locomotive, mileage M, the distance D apart from next critical importance.If the information obtained is included eventually
Stop signal, then it is out of service, otherwise perform（6）Step.
（6）The locomotive driving speed of current video play position is inquired about in whole record：Step（5）Update locomotive driving
After information, the current mileage M of locomotive last calculate relatively may have occurred change.Therefore first is inquired in being recorded from whole process
Bar mileage is located at the record after M.This record can preferably describe the transport condition of locomotive in video, therefore take this to remember
Locomotive driving speed of the speed as current video play position in record.
（7）Currently playing frame per second is estimated using video traveling speed and locomotive driving real time information source travel speed：Note step
Suddenly（6）Locomotive speed is v in the video inquired, it is known that the current driving speed that locomotive driving real time information source provides is V, then
In order to keep the consistent of video playing and driving information, ratio V/v, that is, video should accelerate the multiple played（When V/v is less than 1
Effect is to slow down broadcasting）.Particularly point out and represent that the situation of locomotive parking occurs here in video if v=0, is i.e. v=0 is corresponding
Frame is to repeat each other, need to only skip the frame of v=0 and the whole record entry of v=0 at the same time.
Assuming that the frame per second of video in itself is r, then the play frame rate estimated at this time is R0=V/vr。
（8）Update mileage error e：The thinking for introducing mileage error e, step are introduced first（7）Gained play frame rate R0Can
To keep the consistent of video playing and driving information substantially.But it is limited to whole process and is recorded in temporal discreteness, step（7）Meter
V used in calculation typically contains small error, these errors by a period of time it is accumulative after can be more obvious, cause video
Play more obvious inconsistent with driving information appearance.For example, it may be possible to locomotive has led in locomotive driving real time information source
Some semaphore has been crossed, and locomotive also has a distance apart from the semaphore in video.
To solve the problems, such as this, it is necessary to play frame rate R0Suitably corrected, obtain final play frame rate R.It is modified
Foundation is current mileage error e（E=0 when initial）, modified R0It is so that amended play frame rate R can subtract for the target of R
Small mileage error.
In order to constantly update e, after obtaining next video frame every time, the corresponding mileage valuation m of next video frame can be all estimated
（Specific estimation mode is shown in step（11））, and last next video frame is current video frame in this calculating.Therefore,
The current mileage M that the mileage valuation m of contrast current video frame and locomotive driving real time information source give, you can renewal mileage error
e=m-M。
（9）Obtain revised play frame rate R：Utilize mileage error e modified R0Mode be not unique.It is overall and
Speech, works as e>When 0（That is the progress of video playing is faster than the traveling progress of signal source）, should suitably reduce R0；Otherwise suitably increase R0。
Because all can be according to e modified Rs in calculating every time0, mileage error e will not be accumulated, thus always be to maintain less value.Below
Example in will provide a kind of specific correcting mode.Without having to pay creative labor, other meet above-mentioned
The correcting mode of rule is readily available.
（10）The refresh rate w of play frame rate R and system plays video is contrasted, plays next frame：Step（8）Calculate
R be probably larger（It is greater than 25）, and requirement of the human eye to play frame rate is limited（It is usually no more than 25）.At this time
It is to waste computing resource to carry out video playing according to R.
Therefore fixed system plays the refresh rate w of video（Such as make w=25）, according to ratio s obtained by R/w from decoding
Frame in sample out and need frame to be shown.Specifically, video is carried out after decoding frame by frame, is shown in the frame decoded per s frames
Show a frame.Work as s>When 1, some frames will not be shown；And work as s<When 1, some frames will be continuously displayed several times.Because s mono-
As be floating number, determine to may relate to floor operation when showing which frame, round up, round up, downward rounding is all can
Capable.
After the definite next frame for needing to play, only it need to once refresh elapsed time i on relatively（With reference to step 4 to the time
It is spaced the definition of i）Afterwards, the next frame shown.
（11）The corresponding mileage of next frame, and return to step are estimated（5）Continue to execute.The corresponding mileage valuation of next frame
m1, it is the mileage valuation m in upper once calculating0On the basis of plus traveling in this time interval i distance.Particularly point out
The last mileage estimation used when once calculating is initial mileage valuation, with reference to step（3）The initial mileage valuation provided
Calculation.In view of current travel speed is V, and modified ratio is R/R0, be easy to get m1=m0+ivr/R0.Here m is made
The valuation that calculates twice is distinguished with being marked with difference, using newest m values in other steps（That is the mileage valuation of next frame）,
Therefore no longer superfluous subscript.Gained mileage valuation m will be in next the step of calculating（8）In be used for update mileage error e.
Repeating the above process can be according to the broadcasting frame for the real time information adjustment video that locomotive driving real time information source gives
Rate, obtains and shows required video frame images to realize the video display effect consistent with driving information.In constantly updating
Journey error will be used for adjustment also can play frame rate, avoid the accumulation of local slight error.
In the method for the locomotive driving real time information source of present invention control video playing, used video, including but
It is not limited to the high clear colorful video that high-definition camera is shot during locomotive driving.Speed, mileage referenced by video etc. are believed
The source of breath is derived whole record, other channels after locomotive operation（Such as gps data acquisition system）Having for obtaining is similar
The data of representation function can also directly apply to the present invention, and the replacement of this form is not required to extra creative work.There is provided
The data source of locomotive real time running information, includes but not limited to LKJ simulation systems（Locomotive operation monitor device）.The present invention with regarding
