Description of the drawings
Fig. 1 is the flow diagram of the subtitle automatic generation method for video camera of the embodiment of the present invention；
Fig. 2 is the structure diagram of device automatically generated for the subtitle of video camera of the embodiment of the present invention.
Specific embodiment
Referring to Fig. 1, Fig. 1 is the flow signal of the subtitle automatic generation method for video camera of the embodiment of the present invention
Figure.As shown in Figure 1, the subtitle automatic generation method for video camera includes：
Step S10：Obtain the time synchronization information generated during video capture.
Wherein time synchronization information is specifically referred in video capture, and the current point in time of the video of acquisition is either current
For which frame.
Step S11：It is synchronous to obtain subtitle configuration parameter meaning according to time synchronization information and preset subtitle configuration parameter
The information shown.
The subtitle configuration parameter, which is mainly used for description, needs to obtain which information as subtitle.Specifically, subtitle is configured
Parameter can include：Subtitle auxiliary information and subtitle type information.During video capture, based on the preconfigured word of user
Curtain configuration parameter can automatically synchronize the words such as Weather information when obtaining shooting time information, shooting ground information, shooting
Curtain auxiliary information and the model of such as aircraft, the height of aircraft, the posture of aircraft, the course of aircraft, aircraft
Speed, GPS (Global Positioning System, the global positioning system) location informations of aircraft and aircraft
With the subtitles type information such as the distance of origin.
Subtitle configuration parameter can also further include display parameter information, be used to indicate display side in video
Formula, display parameter information can include the information such as display location, font size and display color as needed.
Step S12：The information of acquisition is handled according to time synchronization information, obtains to show in the video taken
The caption information shown.
Generating subtitle, there are two types of modes, and a kind of is that the corresponding information got is embedded into inside video pictures, this side
The video of formula generation is directly played it is seen that subtitle is embedded in the inside.Another kind is to generate a band timestamp information simultaneously
With the subtitle file for needing text information to be shown, this subtitle file, can be by video player due to band timestamp
It identifies and is come out when playing according to time showing.
In embodiments of the present invention, time synchronization information and preset subtitle are obtained by synchronous during video capture
The information indicated by parameter is configured, and the information of acquisition is handled according to time synchronization information, obtain to take
The caption information shown in video, it is easy to operate, user is not needed to after the completion of recording, then does the work of heavy subtitle addition
Make, meet user about subtitle generate automate, intelligence demand.
In more specific embodiment, obtain in the time synchronization information generated during video capture the step of it
Before, the configuration parameter of typing on user configuration interface is received, and store the configuration parameter of typing as subtitle configuration parameter, it is complete

It closes.For example, if necessary to which flying speed is shown, then receive from the extraneous flying speed got at this time.User can select
Select the combination of any one or more in above-mentioned subtitle configuration parameter.
In embodiments of the present invention, time synchronization information is for sychronization captions, that is, is controlled specifically in which picture
Any subtitle configuration parameter shown.Different subtitle configuration parameters can be put in different times to be shown.
In step s 12, the method for caption information for obtaining to show in the video taken can be in video
It obtains to take by the correspondence image frame in the information insertion video of acquisition according to time synchronization information in shooting process
Video in the caption information that shows so that just directly it can be seen that subtitle is embedded in picture during video playing.Or also may be used
To be to carry timestamp and the subtitle file of the information obtained according to time synchronization information generation in the shooting process of video, and
Video is loaded into, obtains the caption information that can be shown in the video taken.Wherein timestamp is used to indicate video player knowledge
Not corresponding caption information and the caption information that the corresponding time is shown according to timestamp.
In embodiments of the present invention, by obtaining the time synchronization information generated during video capture；According to the time
Synchronizing information and preset subtitle configuration parameter, the synchronous information obtained indicated by subtitle configuration parameter；Believed according to time synchronization
Breath handles the information of acquisition, obtains the caption information that can be shown in the video taken, easy to operate, does not need to use
Family is after the completion of recording, then does the work of heavy subtitle addition, meet user about subtitle generate automate, intelligence
Demand.And it may insure that certain real time datas can normally be collected as subtitle, meet word of the user to real time data
Curtain demand.
Fig. 2 is the structure diagram of device automatically generated for the subtitle of video camera of the embodiment of the present invention.Such as Fig. 2 institutes
Show, include for the device 10 that automatically generates of subtitle of video camera：Time synchronization module 12, data obtaining module 13 and subtitle
Generation module 14.The time synchronization information that time synchronization module 12 generates for acquisition in the shooting process of video.Information obtains
Modulus block 13 is connect with time synchronization module 12, for parameter to be configured according to time synchronization information and preset subtitle, is synchronized and is obtained
Take the information indicated by subtitle configuration parameter.Subtitle generation module 14 is connect with data obtaining module 13, for same according to the time
Step information handles the information of acquisition, obtains the caption information that can be shown in the video taken.This is enabled to
During video capture automatic synchronization generate subtitle, meet user about subtitle generate automate, intelligence demand.
In embodiments of the present invention, configuration module 11 is further included for the device 10 that the subtitle of video camera automatically generates, matched
Module 11 is put for before time synchronization module 12 obtains the time synchronization information generated during video capture, receiving and using
