Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model is by the orderly arrangement of a plurality of video cameras, make the coverage of a plurality of video cameras cover 360 degree, realize 360 degree pan-shots, the image that each video camera is taken sends to background system and carries out anastomosing and splicing and handle again, be made into complete, panoramic video picture clearly, realize the panoramic video monitoring.
Referring to Fig. 1, the utility model panoramic video monitoring system first embodiment is shown, this system comprises the video camera 11 and the video processing module 12 of default number, and the video camera 11 of default number is connected with video processing module 12 respectively, and the coverage of the video camera 11 of default number covers 360 degree; Video processing module 12 comprises cylinder projection submodule 121, the threshold value fusant module 122 that connects successively, and video-splicing submodule 123.
The video camera 11 of default number can be 6,6 video cameras 11 are on same plane, become 60 degree angles to be arranged in a circumference successively, the image pickup scope of each video camera is greater than 60 degree, and the image pickup scope of such 6 video cameras just can cover periphery 360 degree fully, realizes 360 degree pan-shots.
The video pictures that each video camera 11 will be taken separately sends to cylinder projection submodule 121.Each video pictures that 121 pairs of cylinder projection submodules receive carries out the cylindricality projection.The image projection formula that adopts is:
Wherein, P (x y) is any one pixel on the real scene image, and P (x ', y ') be the point coordinates after the projection.Wherein, W and H are respectively the width and the height of real scene image.F is the pixel focal length of video camera 11.
In order to make splicing regions level and smooth, improve picture quality, threshold value fusant module 122 adopts smooth algorithm promptly to be fade-in the method that gradually goes out, and makes color transition gradually, to avoid the fuzzy and tangible border of image.
Threshold value fusant module 122 slowly carries out the transition to second width of cloth image at lap by preceding piece image, and the pixel value in doubling of the image zone is pressed the synthetic new image of certain weight addition.If the RGB component value of the corresponding pixel points of corresponding front and back two width of cloth doublings of the image part is respectively r
