Abstract
A kind of video-splicing result multihead display and control method, the many displays sequential up and down for showing will be used for, the resolution ratio of resolution ratio and display according to splicing result, it is principle according to the preceding screen of order is filled up, cutting is carried out to splicing result and is shown to successively on corresponding screen, realize the multihead display of splicing result；Picture centre with splicing result realizes the zoom control to splicing result as reference point according to image interpolation algorithm, and according to the multihead display of the image size real-time update image after scaling；When method display is carried out to splicing result, center with image is as reference point, the mouse moving event after left mouse button is pressed to user to respond, and realizes the dragging control to splicing result, and according to the multihead display of the picture position real-time update image after dragging.
Description
Technical field
The present invention relates to digital audio-video technical field, and in particular to a kind of video-splicing result multihead display and control method.
Background technology
The implementation process of video-splicing is broadly divided into image registration, image co-registration and result and shows three processes.In actual applications,
It is frequently necessary to carry out the splicing of multi-path high-definition video, by taking the splicing of the HD video of 5 road 1080P as an example, it is assumed that each splicing shooting
Head or so order is arranged, the overlapping region for having 20% or so between each camera, then the image resolution ratio of splicing result is about
8100*1080, splicing result is limited considerably beyond the resolution ratio of current usual hardware display, and thus resulting in cannot be to splicing
Result is shown according to original resolution.Further, since service needed, it is often necessary to splicing result is zoomed in and out, is pulled
Deng control.
The content of the invention
It is an object of the invention to be directed to actual service needed, a kind of multihead display and controlling party to video-splicing result is proposed
Method, realizes the good displaying to video-splicing result.
Technical scheme is as follows：
A kind of video-splicing result multihead display and control method, it is characterised in that：
(1) many displays sequential up and down for showing will be used for, the resolution ratio and display according to splicing result
Resolution ratio, is principle according to the preceding screen of order is filled up, and cutting is carried out to splicing result and is shown to successively on corresponding screen,
Realize the multihead display of splicing result；
(2) picture centre with splicing result realizes the zoom control to splicing result as reference point according to image interpolation algorithm,
And according to the multihead display of the image size real-time update image after scaling；
(3) splicing result is carried out method show when, the center with image as reference point, after pressing left mouse button to user
Mouse moving event responded, realize to the dragging of splicing result control, and according to the picture position real-time update after dragging
The multihead display of image.
The present invention exceeds the situation of monitor resolution for video-splicing result, it is proposed that a kind of splicing result multihead display and control
Method processed, breaches the resolution limitation to separate unit display, realizes splicing result and is sequentially shown on many displays.Simultaneously
Controlled by the scaling to splicing result, dragging etc., realize the good displaying to splicing result.
Brief description of the drawings
Fig. 1 is the display arrangement schematic diagram of multihead display of the invention.
Specific embodiment
Specific implementation of the invention is as follows：
(1) many displays sequential up and down for showing will be used for, the resolution ratio and display according to splicing result
Resolution ratio, is principle according to the preceding screen of order is filled up, and cutting is carried out to splicing result and is shown to successively on corresponding screen,
Realize the multihead display of splicing result；
(2) picture centre with splicing result realizes the zoom control to splicing result as reference point according to image interpolation algorithm,
And according to the multihead display of the image size real-time update image after scaling；
(3) splicing result is carried out method show when, the center with image as reference point, after pressing left mouse button to user
Mouse moving event responded, realize to the dragging of splicing result control, and according to the picture position real-time update after dragging
The multihead display of image.
Below by taking the splicing of the HD video of 4 road 1080P shown in Fig. 1 as an example, the multihead display of splicing result is briefly described
And control method.
In the realization of multihead display, the resolution ratio of resolution ratio and display according to splicing result, it is determined that required display
Number, while according to display put order determine display numbering, the image resolution ratio shown in Fig. 1 shown in solid box
It is 3500*2000, the monitor resolution shown in dotted line frame is 1920*1200, therefore needs 4 displays to realize tying splicing
The complete display of fruit, display is denoted as 1,2,3, No. 4 according to putting position.Being filled up completely with the less display of label in realization
Device carries out cutting for principle to splicing result, will splicing result upper left side part (top left co-ordinate be (0,0), bottom right angular coordinate
It is (1920,1080)) shown on No. 1 screen, (top left co-ordinate is (0,1080) to lower left hand portion, and bottom right angular coordinate is
(1920,2000)) shown on No. 2 screens, (top left co-ordinate is (1920,0) to upper right side portion, and bottom right angular coordinate is
(3500,1080)) shown on No. 3 screens, (top left co-ordinate is (1920,1080), and bottom right angular coordinate is for lower right side part
(3500,2000)) shown on No. 4 screens, it is achieved thereby that the different zones of splicing result are shown in different displays order
Show, be finally reached the purpose of splicing result multihead display.In the control realization to splicing result, with the center of splicing result
Point is reference, and diminution, the amplification to image are realized by image interpolation algorithm, while after display is amplified to image, leading to
Crossing carries out response realization to mouse traveling time according to the dragging of image control.
