Step S45, according to third color value CABIt merges, obtains after handling target video picture, current video picture
It is merged to new target video picture, and by new target video picture with the video pictures of any adjoining, until all views
Frequency picture is fused, and obtains final 3 d video images.
Specifically, third color value C is being obtainedABAfterwards, according to third color value CABTo target video picture and work as forward sight
The color value of frequency picture is handled, so that the color value of target video picture and current video picture is third color
Value CAB, to complete the fusion to target video picture and current video picture.Further, it completes to draw the target video
After the fusion of face and current video picture, using obtained video pictures as new target video picture, and one is chosen again
A video pictures adjacent with new target video picture are completed to melt the two again as new current video picture
It closes, repeats the above process, until when all video pictures permeate a video pictures, to obtain final three-dimensional view
Frequency image.
It is handled by the color value to video pictures, and all video pictures is permeated video pictures, solution
The problem for causing video pictures edge stiff because of color difference problem between adjacent video of having determined picture improves final three-dimensional view
The display effect of frequency image.
Step S5, output show final 3 d video images.
The present embodiment maps to entire video area by the video monitoring picture for shooting at least two cameras simultaneously
Threedimensional model on, obtain the preliminary 3 d video images of entire video area, then handle preliminary 3 d video images,
Fused final 3 d video images are obtained, the video pictures that each camera is shot carry out splicing fusion, thus
A final 3 d video images to entire video area facilitate work so as to avoid the divided problem of monitored picture
