The video intercepting method of the embodiment of the present application is suitable for the electronic equipments such as desktop computer, laptop, passes through this
The video intercepting method of application is conducive to be truncated to the higher video-frequency band of frame stabilization, to be conducive to improve the view being truncated to
The quality of frequency range.
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall in the protection scope of this application.
Referring to Fig. 1, it is a kind of a kind of flow diagram of video intercepting method provided by the embodiments of the present application, this reality
The method for applying example may include:
S101 obtains the corresponding motion state data set of video and the video to be processed.
Wherein, which is collected by mobile terminal, which includes: in the mistake for acquiring the video
Cheng Zhong, motion state data of the mobile terminal at the different acquisition moment.
Such as, while mobile terminal acquires video, the motion state number of the mobile terminal meeting continuous collecting mobile terminal
According in this way, each acquisition moment collected video frame can correspond to mobile terminal in the motion state data at the acquisition moment.
For another example, while mobile terminal acquires video, mobile terminal can acquire the mobile terminal according to the interval of setting
Motion state data.
It is understood that the motion state data of mobile terminal can reflect out user in the process for shooting the video
In, the stability of mobile terminal.Such as, mobile terminal, which exists, shakes, in the case where the continuous mutation of position, the stability of mobile terminal
Can be poor, correspondingly, the motion state data of mobile terminal can also have biggish variation.
Wherein, the stability of mobile terminal influences whether the quality of the video pictures of mobile terminal shooting, to influence
To the stability of video pictures.Such as, when shaking occurs in mobile terminal, the pictured scene of mobile terminal shooting will appear prominent
Become, image quality is poor.
It is understood that the motion state data of the mobile terminal can be there are many different possibility, such as mobile terminal
Motion state data can be for change in location data etc..
Optionally, the motion state data of the mobile terminal can collect at least one of mobile terminal sensor
Sensing data.Correspondingly, the motion state data set may include: the motion state for characterizing the mobile terminal
Sensing data set, wherein during the sensing data set is included in the acquisition video, the mobile terminal is at least
A kind of sensor is in different moments collected sensing data.
Such as, sensing data may include following one or more:
The collected gyro data of gyroscope in mobile terminal, e.g., the gyro data can be mobile terminal
Angular speed, specifically, the angular speed may include the angular speed in three orthogonal axial directions；
The collected acceleration of acceleration transducer in mobile terminal；
The collected gravimetric data of gravity sensor in mobile terminal.
S102, according to the corresponding motion state data set of the video, determined from video the acquisition moment it is corresponding should
The stability of mobile terminal meets at least one video cut point of first condition.
Wherein, the acquisition moment which can meet first condition by the stability in mobile terminal is acquired
Location point of the video frame in the video.
It is understood that the corresponding motion state data set of video, which can reflect out mobile terminal, is shooting the video
During, motion state data of the mobile terminal at the different acquisition moment therefore can based on the motion state data set
To determine mobile terminal in the stability at different acquisition moment.Correspondingly, can be to determine the stabilization in mobile terminal in video
Property meet the collected video location point of institute of each acquisition moment of first condition to get to video cut point.
In the embodiment of the present application, which can be set as needed.
In view of in the case where the stability of mobile terminal is poor, the quality of mobile terminal acquisition is also poor, be not suitable for
For carrying out video analysis, therefore, the video in the video corresponding to the stability of the mobile terminal poor acquisition moment
Location point is not suitable as the content in video-frequency band to be analyzed.Correspondingly, the first condition is for characterizing mobile terminal
Stablize the condition of sexual incompatibility acquisition image.Such as, first condition can be more than setting amplitude for stability change amplitude.
Optionally, if motion state data set includes: at least one of mobile terminal during acquiring video
Sensor, can be collected at least at the different acquisition moment according to mobile terminal in different moments collected sensing data
A kind of sensing data determines that acquisition moment corresponding sensing data amplitude of variation is greater than amplitude threshold at least from video
One video cut point.
It such as, then can be with the gyroscope of some acquisition moment mobile terminal by taking sensing data is gyro data as an example
Data are more than given threshold in any one axial amplitude of variation, it is determined that and the stability of mobile terminal meets first condition,
To which video location point corresponding with the acquisition moment in the video is determined as video cut point.
S103 intercepts at least one view using the video cut point if video cut point meets second condition from video
Frequency range.
Wherein, the second condition is different from first condition, which is that further judgement is based on the video cut point
If appropriate for the condition of interception video-frequency band, specifically can be set as needed.
In a kind of possible situation, it can come in conjunction with the feature for the video-frequency band that can be intercepted based on the video cut point
The video cut point is analyzed if appropriate for the cut point as interception video-frequency band.Such as, if the video cut point and the video are cut
Candidate video section before point between a nearest video cut point meets second condition, then from the candidate video section interception to
A few video-frequency band.
Wherein, the candidate video section before the video cut point and video cut point between a nearest video cut point is full
Sufficient second condition can characterize the candidate video section and be suitble to interception as the video-frequency band for being used for video analysis.
Such as, in one implementation, if the video cut point is cut with a video nearest before the video cut point
The video quality of candidate video section between cutpoint conforms to quality requirements, then it is assumed that video cut point meets second condition.Wherein,
The video quality of candidate video section can angularly reflect from the image quality of candidate video section and resolution ratio etc..
For another example, in another implementation, if a nearest view before the video cut point and the video cut point
The video length of candidate video section between frequency cut point is more than duration threshold value, then it is assumed that the video cut point meets Article 2
Part.It is understood that must not if the video length of the candidate video section between two adjacent video cut points is too short
The candidate video section is analyzed, therefore, if the view of the video-frequency band intercepted out based on the two adjacent video cut points
Frequency duration is also inevitable shorter, to not meet video analysis requirement., whereas if the candidate between two adjacent video cut points
The video length of video-frequency band is longer, on this basis, then video-frequency band interception can be realized based on the two adjacent video cut points.
It is understood that can then abandon and be unsatisfactory in the case where determining that video cut point meets second condition
The video cut point of second condition, and just with each video cut point for meeting second condition, it can be intercepted from video
At least one higher video-frequency band of picture quality out.
In specific implementation, it can according to need possible there are many realizing.It such as, can be from being determined by video in video
Initial point, video end point and meets the adjacent video point of any two in the video cut point of second condition and surround and do not wrap
Video-frequency band containing the video cut point for being unsatisfactory for second condition, and intercept the video-frequency band determined.
For example, it is assumed that determining that 3 video cut points respectively are video cut point 1,2 and of video cut point in video
Video cut point 3, it is assumed that be that video cut point 2 does not meet second condition, then being cut by the starting point, end point, video of video
The video-frequency band that cutpoint 1, video cut point 3 are separated out includes: the video-frequency band 1 that the starting point of video is formed with video cut point 1, depending on
The video-frequency band 2 that the end point of frequency cut point 3 and video is constituted, it is seen then that video cut point 2 does not determine interception video as user
The location point of section.
Particularly, for each video cut point, if a nearest view before the video cut point and video cut point
Candidate video section between frequency cut point meets second condition, then confirms that the video cut point meets second condition, in this kind of feelings
Under condition, it is contemplated that the satisfactory quality of the candidate video section then can be and intercept at least one view from the candidate video section
Frequency range.Such as, it is a video-frequency band by candidate video section interception, or intercepts out multiple video-frequency bands from the candidate video section.
Such as, it will again be assumed that video cut point 1, video cut point 2 and video cut point 3 are successively determined in video, and are regarded
Candidate video section between the nearest video cut point, that is, video cut point 1 of frequency cut point 2 and front does not meet second condition,
In that case, meet in the video second condition candidate video section include: video starting point and video cut point 1 it
Between video-frequency band S1, the video-frequency band S2 between video cut point 2 and video cut point 3, the end point of video cut point 3 and video
Between video-frequency band S3, in this way, at least one video can be intercepted out from video-frequency band S1, video-frequency band S2, video-frequency band S3 respectively
Section.Compared with previous examples, the candidate video section that this kind can be used for intercepting video-frequency band increases, and due to each candidate video section
Belong to mobile terminal collected video-frequency band under stable case, thereby may be ensured that video figure in the video-frequency band finally intercepted out
The stability of picture, is conducive to video analysis.
Through above scheme it is found that while obtaining video to be processed, it can also obtain mobile terminal and acquire the view
The motion state data at the different acquisition moment of frequency, in this way, by setting first condition and second condition, it can be according to mobile whole
The motion state data at the different acquisition moment for acquiring the video is held, the corresponding shifting of acquisition moment can be determined from video
At least one lower video cut point of stability of dynamic terminal, and be conducive to preferable based on video cut point interception mass
At least one video-frequency band, thus advantageously allow interception video-frequency band be more suitable for video analysis.
It is understood that can generally set the video intercepting duration of video-frequency band interception in view of in practical application, and press
According to the video intercepting duration, video is intercepted from the video, therefore, the application can be cut in conjunction with video cut point and according to video
The video intercepting point for taking duration to determine, to intercept at least one video-frequency band from video.
Such as, referring to fig. 2, it illustrates a kind of flow diagrams of another embodiment of video intercepting method of the application, originally
The method of embodiment may include:
S201 obtains the corresponding motion state data set of video and the video to be processed.
Wherein, which is collected by mobile terminal, which includes: in the mistake for acquiring the video
Cheng Zhong, motion state data of the mobile terminal at the different acquisition moment.
S202, according to the corresponding motion state data set of the video, determined from video the acquisition moment it is corresponding should
The stability of mobile terminal meets at least one video cut point of first condition.
Wherein, above step S201 and S202 may refer to the related introduction of preceding embodiment, and details are not described herein.
S203 determines at least one video intercepting point according to video intercepting duration from the video.
Wherein, which, which can according to need, presets or is inputted by user.
It is understood that be based on the video intercepting duration, determine video intercepting point mode can also there are many.Such as,
In one possible implementation, according to the video intercepting duration, at least one video intercepting point can be determined from video,
So that the video length between the adjacent video intercepting point of any two is the video intercepting duration.
For example, then can be set a length of 100 when video intercepting when needing to intercept in the case where a length of 100 seconds videos
Second, in this way, in video at interval of 100 seconds be a video intercepting point.
One of the above mode is that all video intercepting points of can be used as are determined from video according to video intercepting duration
Location point.
In practical applications, it is also possible to can first be determined current to be intercepted according to the sequencing of frame image each in video
Video intercepting point, and video-frequency band is being intercepted based on the video intercepting point and then is determining next video intercepting point.In this kind
In the case of, step S203 can be according to the video intercepting duration, and current video intercepting point is determined from the video.Such as,
Current video intercepts starting point from video, according to the video intercepting duration, determines after the video intercepting starting point of the video
Current video intercepting point.For example, duration of the video intercepting starting point later and apart from the video intercepting point will be in video
For the video intercepting duration location point as video intercepting starting point.Correspondingly, subsequent can be determined based on the video intercepting point
Current video-frequency band to be intercepted.
It should be noted that the sequence of step S202 and S203 is not limited to shown in Fig. 2, in practical applications, may be used also
To be to be performed simultaneously step S202 and S203, either, first carries out step S203 and execute step S202 again.
S204 utilizes the video cut point and at least one video intercepting if video cut point meets second condition
Point intercepts at least one video-frequency band from video.
Wherein, the second condition met needed for the video cut point may refer to the related introduction of preceding embodiment.
In the present embodiment, it using the video cut point and at least one video intercepting point, is intercepted at least from video
The mode of one video-frequency band can there are many.Such as, it is determined from video by video starting point, video end point, video intercepting
Point meets the adjacent video point of any two in the video cut point of second condition and surrounds and be unsatisfactory for second condition
Video cut point video-frequency band, and intercept the video-frequency band determined.
It for another example, can be from the time for meeting second condition in the case where needing to judge that candidate video section meets second condition
It selects and intercepts at least one video-frequency band in video-frequency band.Wherein, if video intercepting point is not present in candidate video section, by the candidate
Video-frequency band interception is a video-frequency band, if needed using this extremely there are at least one video intercepting point in candidate video section
The candidate video section is segmented by a few video intercepting point to be intercepted.
In order to make it easy to understand, for example:
As shown in figure 3, it illustrates determine showing for multiple video intercepting points and multiple video cut points from video
It is intended to.
As seen from Figure 3, there are two video intercepting point and three videos for tool between the starting point and end point of video
Cut point, two of them video intercepting point are followed successively by intercept point 1 and intercept point 2 in Fig. 3, and three video cut points are followed successively by and cut
Cutpoint 1, cut point 2 and cut point 3.
Wherein, the candidate video section between cut point 2 and the cut point 1 of front one is unsatisfactory for second condition, such as the candidate
The duration of video-frequency band is too short or video effect is poor etc..And the candidate between other cut points and the nearest separation of the front
Video-frequency band is all satisfied second condition.In that case, the view between the starting point of video and the cut point 1 of video can be intercepted
Frequency range, and the video-frequency band between cut point 1 and cut point 2 will not then be intercepted and can directly give up.
Correspondingly, the nearest video cut point in the front of cut point 3 is cut point 2, and the cut point 3 and cut point 2 it
Between in the candidate video section that constitutes there are two video intercepting points, and the two video intercepting points are by the cut point 2 and cut point 3
Between candidate video section be divided into 3 sections, correspondingly, this 3 video-frequency bands can be intercepted.In this way, can be truncated to cut point 2 with
Video-frequency band, intercept point 1 between intercept point 1 and the video-frequency band between intercept point 2 and the view between intercept point 2 and cut point 3
Frequency range.
Finally, the video-frequency band of the end point of cut point 3 and video can also be truncated to a video-frequency band.Certainly, in reality
In the application of border, the video-frequency band that the end point of starting point or video for cut point and video is constituted can also first judge
Whether the lower video-frequency band meets second condition, if it is satisfied, then intercepting corresponding video-frequency band；Otherwise, then the view can not be intercepted
Frequency range.
It is understood that if only intercepting video-frequency band from the video in Fig. 3 according to video intercepting duration, then can
Be truncated to three video-frequency bands, be respectively as follows: video-frequency band between the starting point of video and intercept point 1, intercept point 1 and intercept point 2 it
Between video-frequency band, the video-frequency band between intercept point 2 and the end point of video.
But it can be seen that in the video-frequency band between the starting point of video and intercept point 1 that there are mobile terminals to exist in conjunction with Fig. 3
An acquisition moment collected video point in the unstable situations such as shaking, i.e., (Fig. 3 is to be with a cut point to cut point 1
Example, mobile terminal once shakes it is possible that each point is in collected video in continuous a period of time in practical applications
The case where image unstable cut point) so that this section of video-frequency band can have the unstable images such as scene mutation, lead to benefit
It is larger that the obtained analysis result error of video analysis is carried out with this section of video-frequency band.Correspondingly, the end point of intercept point 2 and video
Between video-frequency band there is also same problem.
However, in conjunction with presented hereinbefore it is found that in the embodiment of the present application, fully taking into account mobile terminal in unstable feelings
The interference of video captured by condition, to not only intercept video according to the video intercepting point determined based on video intercepting duration
Section, further accounts for belonging to mobile terminal collected each video point in unstable situation in video, so that video be carried out
More careful interception, so that each video point in each video-frequency band inside intercepted out is not admitted to mobile terminal and pledges love in shakiness
Collected video point under condition, thus the stability of the picture quality of the guaranteed each video-frequency band intercepted out.
It is understood that by there is video intercepting point in this present embodiment, therefore, the Article 2 in the embodiment of the present application
Part can also have other possible situations.Such as, the video cut point meet second condition can be with are as follows: the video cut point and video
Relationship between intercept point meets second condition.Such as, in one case, before the video cut point and the video cut point
There are in the case where at least one video intercepting point between a nearest video cut point, from least one video intercepting point
The determining preceding video intercept point nearest with the video cut point, then need to detect the video cut point and the preceding video intercept point it
Between candidate video section whether meet second condition.
For another example, in another situation, a nearest video is cut after the video cut point and the video cut point
There are in the case where at least one video intercepting point between point, the determining and video is cut from least one video intercepting point
The nearest rear video intercept point of point, then needing to detect the candidate video section between the video cut point and the rear video intercept point is
It is no to meet second condition.
Wherein, whether candidate video section meet second condition and can be the video quality of the candidate video section and accord with herein
Whether the video length for closing quality requirement or the candidate video section is more than duration threshold value.
It is understood that some and video intercepting point interval can be given up by setting both the above second condition
Compared with close or poor with the video quality of the video-frequency band of video intercepting point composition video cut point, it is based on so as to not intercept
