Embodiment and embodiment in feature can be combined with each other.
According to an aspect of the present invention, it proposes a kind of streaming media video categorization based on observing and controlling flight path information,
Include the following steps：
The first step, the original observing and controlling track data of extraction unmanned plane and sensor load posture information, navigate to the original observing and controlling of unmanned plane
Mark data and the frequency of sensor load posture information are judged, if frequency is excessively high, is carried out down conversion process, are obtained unmanned plane
Observing and controlling track data.
Preferably, as shown in Figure 1, the step of extracting the original observing and controlling track data of unmanned plane and sensor load posture information
Including：
1.1 judge the original observing and controlling track data of unmanned plane and whether sensor load posture information extracts success, and extraction failure is then
Terminate extraction flight path step, extracts and successfully then carry out step 1.2；
1.2 track data frequency resolutions calculate the original observing and controlling track data of unmanned plane and sensor load posture of this flight path
Whether information is more than some frequency, then carries out down conversion process, for example, wherein some frequency can take 1 point/1000 milliseconds, if boat
The frequency of mark data is more than the frequency, then drops to the frequency；
Treated data are stored in designated storage location by 1.3.It is to be understood that treated, data can not also be through depositing
Storage, is directly transmitted by wired or wireless mode.
The reason of track data or sensor load posture information progress down conversion process, is, usual initial data
Frequency is very high, and the data of such high frequency are not needed when cataloguing video data, it is therefore desirable to carry out frequency reducing to initial data
Processing.The factors setpoint frequency threshold value such as accuracy according to cataloguing, if the track data frequency of this flight path is more than the setting
Frequency threshold, for example, the data of track points are more than 1 point/1000 milliseconds, then it is down-sampled to the progress of the track data of this flight path,
Realize down conversion process.Conversely, if the track data frequency of this flight path is less than the frequency threshold that frequency is higher than the setting, to this
The track data of flight path carries out a liter sampling.Same treatment can also be made for sensor load posture information.
Second step extracts the original streaming media video data obtained by unmanned plane, to original streaming media video number
According to being judged, if original streaming media video data is unsatisfactory for integrality and/or continuity requirement, carry out splicing and/
Or frame processing is mended, obtain streaming media video data.
Preferably, as shown in Fig. 2, the step of extracting original streaming media video data includes；
2.1 judge whether to extract successfully, for original streaming media video data, terminate to extract original Streaming Media if extracting failure
Video data step carries out step 2.2 if extracting successfully；
2.2 judge the integrality and/or continuity of original streaming media video data, for example, integrality judgement includes：Judge former
Whether beginning streaming media video data is that entire flight path is captured in the process, if there are broken etc.；Continuity judges：Sentence
Original streaming media video data break with the presence or absence of frame losing etc.；
If 2.3 original streaming media video datas meet integrality and/or continuity requirement, streaming media transcoding operation, example are carried out
Such as, transcoding operation includes the watermark addition of video, the conversion of resolution of video, format conversion, video-encryption etc., obtains Streaming Media
Then video data executes step 2.5；
If 2.4 original streaming media video datas are imperfect, according to degree of crushing splicing to the original streaming media video
Processing；If original streaming media video data is discontinuous, which is carried out to mend frame processing, is then executed
Step 2.3；
2.5 data after the completion of streaming media video data transcoding operation are stored to designated position as video file and are waited for down
Primary cataloguing.It is to be understood that treated, streaming media video data can not also be stored, directly by wired or
Wireless mode is transmitted.
Preferably, the step of splicing specifically includes：
Based on shooting time information, the lack part of original streaming media video data is searched, is judged to be crushed journey according to lack part
Degree plans path of taking photo by plane again if degree of crushing is higher than threshold value；It, will if degree of crushing is less than or equal to certain threshold value
Other videos or video clip along flight path photographs where the lack part are spliced in the original streaming media video data.
Preferably, specifically, it will be spliced to along other videos of flight path photographs where the lack part or video clip
Step in the original streaming media video data includes：
By other videos of video frame and place flight path photographs before and after lack part in original streaming media video data or regard
Video frame in frequency segment carries out comparison lookup by image denoising, feature point extraction, feature registration；
If existing and the video frame phase before and after lack part in original streaming media video data in other videos or video clip
The video frame matched, then by image mosaic, image light modulation and gray-level interpolation by matching in other videos or video clip
Video clip between video frame is inserted into the lack part of the original streaming media video data, is regarded to obtain complete Streaming Media
Frequency evidence.
For example, lack part is the video between the 10th minute to the 11st minute in the original streaming media video data, then
It will be on the first video frame B and this section of video place flight path from the last one video frame A and the 11st minute before the 10th minute
Other videos of shooting or the video frame in video clip are compared by image denoising, feature point extraction, feature registration, if
There is video frame A ', the B ' to match with video frame A, B of original streaming media video data in some video, is then spelled by image
It connects and respectively splices video frame A ' and video frame A, video frame B ' and video frame B are spliced, pass through image light modulation and gray-level interpolation
Video clip between video frame A ' and B ' is inserted between the video frame A and B of the original streaming media video, is obtained complete
Streaming media video data.It should be understood that the video frame in streaming media video before lack part or after missing can be one
A video frame can be one group of video frame.
By concatenation, captured video can be made full use of, avoids being repeated several times and shoots, and after capable of improving
Purpose of sequeling efficiency.
Preferably, the step of carrying out benefit frame processing to video specifically includes：
To original streaming media video data according to time piecemeal, several video data block are obtained；
Each data volume size in the block to video data judges, if the data volume of the block is less than threshold value, tentatively
Determine that there are frame loss conditions for the video data block；
It is searched in the video data block using dichotomy, determines specific frame losing position；
It carries out patching up frame operation in the frame losing position.
Specifically, it is assumed that the data volume size of each frame of captured video is identical, and video size per minute is 40
Million.By taking the video extremely planted as an example, ten minutes videos are divided into ten data blocks, video data conduct per minute first
One data block judges the data volume size of each data block respectively.If the data volume of some data block is less than 40,000,000, tentatively
Determine that there are frame loss conditions for the video data block.It is searched in the video data block using dichotomy, i.e., by the data block
It is divided into first 30 seconds and rear 30 seconds two parts, judges data volume size respectively, if first 30 seconds data volume sizes are less than 20,000,000, sentences
Breaking, there are frame loss conditions for the part, then this is divided into two parts for first 30 seconds with dichotomy and is continued to search for, until determination is specifically lost
Frame position.
It carries out mending frame operation in the frame losing position.For example, the value of the frame image of the frame losing position can take the frame losing position
The mean value of front and back two frames in place, the estimated value of several frames before can also taking at the frame losing position.
Mending frame operation can also be searched by the method judged frame by frame, however for the big video data of data volume,
