Embodiment
The present invention is described more fully with reference to the accompanying drawings, wherein illustrating the exemplary embodiment of the present invention.This
The exemplary embodiment of invention and its illustrate to be used to explain the present invention, but do not form inappropriate limitation of the present invention.
The description only actually at least one exemplary embodiment is illustrative to be never used as to the present invention below
And its application or any restrictions that use.
Following embodiments of the present invention in the video information of mobile terminal captured in real-time by adding dynamic location information
Mode solve the problems, such as that video follow shot place is rationally presented in the video of mobile terminal collection.
Fig. 1 is the schematic flow sheet of present invention one embodiment of the method for coal addition position information in video information.
As shown in figure 1, the embodiment may comprise steps of：
S102, the video that real-time reception mobile terminal is recorded, the video recorded is stored in video management server
In；
S104, real-time reception mobile terminal is when carrying out video record according to the frequency acquisition of setting by being built in movement
The GPS of terminal（Global Position System, global positioning system）The current latitude and longitude coordinates of the mobile terminal of acquisition
（X, y）；
S106, by the current latitude and longitude coordinates of mobile terminal compared with the latitude and longitude coordinates that GPS last time obtains, example
Such as, if the current latitude and longitude coordinates of mobile terminal are（X, y）, last time obtain latitude and longitude coordinates be（X0, y0）, then it is mobile whole
The distance between latitude and longitude coordinates that current latitude and longitude coordinates obtained with last time are held to be expressed as：
S108, if the distance between latitude and longitude coordinates that the current latitude and longitude coordinates of mobile terminal obtained with last time are less than
The acquisition precision of setting, show that the current position of mobile terminal with respect to the change in location very little that last time GPS is obtained, is then ignored current
Latitude and longitude coordinates, do not record the current latitude and longitude coordinates gathered, otherwise record current latitude and longitude coordinates and with it is current
Video record time point corresponding to latitude and longitude coordinates；
S110, cartographic information is inquired about from GPS map information database according to current latitude and longitude coordinates, to obtain with working as
Place name corresponding to preceding latitude and longitude coordinates, the positional information so shown in picture have more relative to latitude and longitude information
Good readability；
Specifically, GIS is passed through（Geographic Information System, GIS-Geographic Information System）System is inverse geographical
Coding techniques, according to the geographical location information of recording location, the cartographic information of inquiry current location from GPS/map database,
And be converted to place name text information；
S112, place name corresponding with video record time point, which is added to record, according to video record time point regards
The fixed position of frequency picture；
Specifically, time shaft is accurately adjusted according to place name captions and video, both is synthesized containing captions

The video image in place processed.
The embodiment is obtained the latitude and longitude information of video record position by setting frequency acquisition by GPS, and longitude and latitude is believed
Breath is converted to place name to improve readability, is then based on renewal frequency that frequency acquisition and acquisition precision determine jointly in institute
The fixed position dynamic renewal place name of recorded video picture.Image spacing shared by this mode recording location information
Recording location information small, but also that video viewers can be made to watch dynamic to update.
Alternatively, needed dynamically update frequency acquisition and acquisition precision during video record according to user.Example
Such as, when the user's movement for carrying mobile terminal is very fast, frequency acquisition and acquisition precision can suitably be increased.It is wherein it is possible to sharp
Acquisition precision is represented with the distance between current latitude and longitude coordinates and previous latitude and longitude coordinates threshold value, distance threshold is smaller, adopts
It is higher to collect precision.
Furthermore, it is possible to place name is shown in a rolling manner in the bottom of institute's recorded video picture, as shown in Figure 2.
When being shown with roll mode, the information can be obtained from picture at any time when user wants and pays close attention to positional information.Enter one
Step ground, the mode of rolling can be incision from left to right, right-to-left incision or stir form.In video pictures bottom explicitly
Point title can cover actual video content as little as possible, because the focus of video is substantially the centre bit close to screen
Put, without the surrounding in screen, therefore the mode of the lower section overlapping text in video pictures can farthest retain original
Some video informations, and can also disperse the notice of beholder as little as possible in the bottom of picture, to improve viewing effect.
Fig. 3 is the schematic flow sheet of the present invention another embodiment of the method for coal addition position information in video information.
As shown in figure 3, the embodiment may comprise steps of：
S302, the frequency acquisition t and acquisition precision s of the geographical location information of collection recording location are set, wherein, position letter
The frequency acquisition t of breath refers to obtain the current GPS location data latitude and longitude coordinates of mobile terminal of recorded video every the t seconds, and t is rounded
Numerical value, acquisition precision s refer to adjacent the distance between coordinate acquisition threshold value twice；
S304, when carrying out video record, the latitude and longitude coordinates of positional information are obtained according to the frequency acquisition of setting（X,
y）；
S306, judge the current latitude and longitude coordinates of the mobile terminal that GPS is obtained（X, y）The latitude and longitude coordinates obtained with last time
（X0, y0）The distance between whether be more than acquisition precision s, i.e. whether be more than setting distance threshold, the distance such as less than set
Threshold value, then return to step S304；
S308, the distance threshold such as larger than set, then record time point and the latitude and longitude coordinates of video record（X, y）；
S310, video management server obtain the geographical location information of recording location in real time, i.e. latitude and longitude coordinates；
S312, cartographic information is inquired about from GPS map information database according to the geographical location information of recording location, obtained
Location name information corresponding with latitude and longitude coordinates；
S314, the rolling place name captions of recording path are shown in the video of recording so that play the video of recording
When, the place that shows in the video of recording is identical with the place shown in institute recording path captions.
It will appreciated by the skilled person that realize that the whole of above method embodiment and part steps can pass through
Programmed instruction related hardware is completed, and foregoing program can be stored in a computing device read/write memory medium, the journey
Sequence upon execution, execution the step of including above method embodiment, and foregoing storage medium can be including ROM, RAM, magnetic disc
With CD etc. is various can be with the medium of store program codes.
