Embodiment
For ease of understanding the present invention, set forth below in conjunction with accompanying drawing.
First introduce the inventive method, please refer to Fig. 1, a kind of video monitoring display packing based on GIS map, comprises step:
101, initialization;
The first unique mark is distributed to each screen point on map; By monitor video signal corresponding for each screen point access large-screen, distribute the second mark comprising the first mark to each monitoring video signal, wherein, the second mark is for representing place name and self numbering at screen point place.Concrete, the first mark can be screen point self numbering; Second mark can be: the location name that screen point self numbering+this screen point is installed;
102, screen point is searched;
After receiving the signal of the screen point that selection need show on map, search the screen point that need show, according to the second mark of the screen point that need show, the monitor video signal that gating is corresponding.
103, screen point is shown.
The monitor video that the screen point that need show is corresponding is presented on large-screen.
The inventive method is based on GIS(Geographic Information System, GIS-Geographic Information System) map, first initialization system, the first unique mark is distributed to each screen point (being equivalent to camera head) on map, by monitor video signal corresponding for each screen point access large-screen, and distribute to monitoring screen signal corresponding to each screen point to comprise the second mark of the first mark, that sets up screen point and large-screen associates corresponding relation; And then map is searched monitor video corresponding to the screen point that need show, by the monitor video display found; When needing to carry out switchings display, need select different screen point on map, compared with traditional large screen display method, can random switching monitoring screen, improve operating efficiency.
In order to flexible and changeable display mode can be provided, such as, show window, the window of 6 row 8 row, the window of 12 row 16 row that 3 row 4 arrange, can be further improved above-described embodiment:
Comprise before 103 steps: the plurality of display modes pre-setting large-screen;
In 103 steps, select the display mode of acquiescence to show, wherein, the display mode of acquiescence is the display mode determined according to ranks number and the resolution of large screen display unit.
As a kind of specific embodiment, be 2*2 according to the ranks number of large screen display unit; Screen resolution is 1024*768; Then can obtain the location parameter giving tacit consent to display mode: (left, top, width, height);
