Detailed description of the invention
Technical scheme and the technique effect reached for making to present invention solves the technical problem that, using are more clear
Chu, is described in further detail the technical scheme of the embodiment of the present invention below in conjunction with accompanying drawing, it is clear that
Described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on this
Embodiment in bright, those skilled in the art obtained under not making creative work premise all its
His embodiment, broadly falls into the scope of protection of the invention.
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Embodiment one
Fig. 1 is the video Eagle-eye Map rendering method flow chart described in the present embodiment, and the present embodiment is applicable to
Show video geographic location Eagle-eye Map during video playback, and realize real-time video and play and in Eagle-eye Map
The situation of the linkage of reason position, the method can be presented device by the video Eagle-eye Map of configuration in computer and hold
OK, as it is shown in figure 1, the video Eagle-eye Map rendering method described in the present embodiment includes:
Step S110, obtain corresponding breviary map according to the geographical position of current video content.
Geographical position according to current video content obtains the method for corresponding breviary map and includes multiple, this reality
Execute example at this and to be not construed as limiting.Such as can according to the attribute of current video (file name of such as video,
Shooting address properties information, shoot the information such as video camera that this video uses) obtain the geographical position of described video
Put, obtain corresponding breviary map according to described geographical position.
Step S120, from described breviary map the geographical position of real-time searching current video content.
Owing in the network of communication lines, the shooting of video is typically to utilize static video camera, what therefore video was used takes the photograph
Camera position is corresponding with position, shooting ground.Therefore this step can be by current video content
The geographical position of shooting main body, obtains the geographical position of this video content.
It addition, also the object video in video content can be identified, according to the geographical position of object video
Obtain the geographical position of video content.
Step S130, in real time described breviary map is presented centered by the geographical position searched, with
Eagle-eye Map as described video.
Eagle-eye Map is a basic function in GIS, Eagle-eye Map, as the term suggests, can be as on Eagle-eye Map
The map shown from aerial vertical view equally consults a map frame position in whole figure.
Described breviary map is presented centered by the geographical position searched, can be by by current video
The geographical coordinate of the geometric center of content can show and realize by center position in the relatively center of Eagle-eye Map.
Such as, specifically can be by obtaining the geographical coordinate of the geometric center of current video content in real time, from described breviary
Geographical coordinate described in real-time searching in map.The geographical position corresponding when the geometric center of video changes
Time, react in described Eagle-eye Map in real time, i.e. in real time the geographical position of the geometric center of video is corresponded to institute
State Eagle-eye Map.Certainly, if in order to avoid Eagle-eye Map switching is excessively frequent, can allow in the geometry of video content
The geographical coordinate of the heart relatively center (within the scope of the default viewing area) of Eagle-eye Map when,
Control Eagle-eye Map not make to switch.
Specifically, described Eagle-eye Map is the position relationship between current and described video, can according to demand and behaviour
Make custom arbitrarily to arrange, such as, described Eagle-eye Map can be shown in the lower left corner of described video window, upper left
Angle, the lower right corner or the upper right corner, at this and be not construed as limiting.
Described Eagle-eye Map can present with the form of the thumbnail of map, in order to the color with video is distinguished,
Form stronger visual contrast, can in real time to described Eagle-eye Map centered by the geographical position searched,
Show with the form of inverse.
The present embodiment obtains corresponding breviary map, from described breviary according to the geographical position of current video content
The geographical position of real-time searching current video content in map, in real time to described breviary map with the ground searched
Reason position centered by present, using the Eagle-eye Map as described video, can realize real-time video play and
Fusion between GIS geographical position presents with fast linked.

Step S230, in real time described breviary map is presented centered by the geographical position searched, with
Eagle-eye Map as described video.
Above-mentioned steps S210-S230 is identical with step S110-130 in embodiment one, and therefore not to repeat here.
The first preset instructions whether is received, if then performing step on step S240, monitoring Eagle-eye Map
S250, otherwise returns step S240.
In the present embodiment, the preset instructions operating Eagle-eye Map refers to that presets is carried out described Eagle-eye Map
The instruction of operation, the finger controlling the operations such as described Eagle-eye Map is amplified, reduces or moves such as preset
Order.
Such as, double-click certain bit map/bitmap mark in Eagle-eye Map, directly current video playback picture can be switched to this
Point position.Mouse moves on to this Eagle-eye Map scope, can be amplified reducing to Eagle-eye Map by mouse roller, can lead to
Cross and click on the mode that pulls and Eagle-eye Map is translated, to reach to observe the purpose of periphery more points position.
In the present embodiment, described first preset instructions refers to preset, for by choosing certain position in Eagle-eye Map
Put, current video is played back to the instruction of this position.Such as preset the first preset instructions for clicking on or double-clicking eagle
Certain position in eye pattern, in Eagle-eye Map, sealing ring etc. is marked in certain region.
Step S250, obtain and on described Eagle-eye Map, receive the geography that the location point of described first preset instructions is corresponding
Position.
Receive the first preset instructions on described Eagle-eye Map if monitoring, then obtain and receive this first preset instructions
Geographical position corresponding to location point.As obtain user double-click Eagle-eye Map time, mouse point correspond to hawkeye
Geographical position in figure.
Step S260, current video content is switched to the video in the geographical position of described correspondence.
After obtaining this geographical position, even if the regarding of geographical position of described correspondence can be switched to current video content
Frequently, it is achieved thereby that Eagle-eye Map and the linkage of video playback.
The present embodiment is on the basis of embodiment one, it is further provided it is right that user is come by operation Eagle-eye Map
Video-frequency playing content carries out the technical scheme selecting to control, and can realize real-time video and play and GIS geographical position
Between fusion present with fast linked.
