Each video surveillance point and camera are bound, and are monitored and are managed by cradle head controllor, and window is divided in system screen
Mouth display.History monitor video is preserved in cradle head controllor, and the window for checking history video is set.
When needing to check video point, a coordinate points are chosen in GIS map, and history monitor video is recalled.
Step 2: centered on the coordinate points, video and graphic being drawn according to default diameter；
It is understood that checking before video point, entire associated video substantially situation is shown, wherein with institute
Centered on the coordinate points of selection, the monitoring view in video and graphic selection GIS map is drawn with radius preset in GIS map
Frequently.
Optionally, the video and graphic drawn can be circle and be also possible to polygon, be not limited thereto.
Step 3: analysis being carried out to the video and graphic and obtains all video points in the video and graphic, and to all videos
Click through line label；
Wherein it is possible to understand, all video points inside video and graphic are obtained, and rower is clicked through to each video
Number, i.e., to itself title on video point table.
Step 4: vision signal corresponding to search video point refreshes the label and all vision signals searched
To list of videos；
Wherein, the corresponding vision signal of search video point, the label of each video point and the vision signal brush searched
List of videos is newly arrived, meanwhile, vision signal load is shown on spelling wall system screen, the load for completing history monitor video is aobvious
Show.
Step 5: according to the list of videos, the positioning video point in the GIS map.
Wherein, according to the list of videos after refreshing, the video point chosen and need to check can be positioned in GIS map；
It is understood that can also check the state of video equipment by list of videos.And event occurs in video equipment
It, can be with Realtime Alerts, to check the state of video equipment by video point in time when barrier.
The embodiment of the present invention is by simply picking coordinate points, centered on coordinate points, is regarded with preset radius to draw
Frequency figure, show history monitor video, after video point all in video and graphic is obtained out, and to each video point carry out
Label searches again for vision signal corresponding to video point later, will search out the label of the vision signal and each video point come
List of videos is flushed to, finally, search video point can be quickly located, convenient for video according to the video flow table after refreshing
It checks and manages.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
