The edge data between local monitoring image that video camera generates；
After carrying out interpolation or homogenizing processing to the edge data determined, synthesis monitoring is carried out with local monitoring image
The corresponding monitoring image in region.
For example, as shown in figure 4, it is illustrated so that two video cameras shoot monitoring area as an example.Shown in Fig. 4 is respectively two
The stacking chart of the local monitoring image of the corresponding acquisition of a video camera: where oblique line portion is the edge image of superposition.Also, such as
Shown in Fig. 5, micro control system can be used rationally to carry out internal focus for video camera, and debugging focus point is carried out in depth of field controlled range
Position, to obtain clearly local monitoring image.
Assuming that two video cameras acquire moment at some, the pixel-matrix of a frame part monitoring image of corresponding acquisition with
RGB mode stores, as shown in Figure 6.In Fig. 6 shown in the left side, for one of video camera acquisition pixel-matrix data Img1 [m,
It n, 3], is the corresponding pixel-matrix data Img2 [m, n, 3] of another video camera, wherein m indicates line number in Fig. 6 shown in the right
According to n indicates column data, and 3 indicate RGB three-dimensional component.For the sake of simplicity, the identification of edge data is carried out by taking R matrix as an example
And processing.R component data are compared according to R1 [m, n] and R2 [m, n], to obtain the column model of edge data
It encloses.
Specifically, the column range of edge data can be obtained according to method as shown in Figure 7, i.e., according to processing function F
(x) successively judge the space length of each each column data of row between R pixel-matrix data R1 [m, n] and R2 [m, n] whether in experience
It is worth in section (- δ ,+δ), and then judges the column range p of edge data.It should be noted that shown in Fig. 7 processed
Journey is that most full processing mode can also press in practical applications according to the valued space of the pixel-matrix data of monitoring image
According to most simplified processing mode, such as only select that wherein several travelings of the valued space of the pixel-matrix data of any one color
Line number it is judged that, to be quickly obtained p value.
Further, after the column range for obtaining edge data, it is also necessary to the edge data within the scope of column
Reasonability judged, and unreasonable edge data is handled.For example, it is assumed that pixel-matrix data are four
Storage, when obtaining a frame data, a video camera shooting edge data for array a=0101,0000,0011,
1100 }, { 0000,0011,0010,0000 }, { 1111,1010,1101,0010 } }, the edge image of another video camera shooting
Data be array b={ 0001,0010,0010,1100 }, { 0000,0011,0010,0000 }, 1001,1011,0011,
0101 } }, according to an expression Δ s=Σ (a of processing function F (x)2-b2), calculate two groups of data space length in
Most short space length whether in | δ | in the range of, to judge the value range of edge data.If most short space away from
From not in section | δ | it is interior, it is determined that the corresponding edge data of the most short space length is unreasonable.These are not conformed to individually
The edge data of reason, herein for convenience handle, can according to the unreasonable edge data and its front and back two rows,
The correlation of the edge data of upper and lower two column, is smoothed.For example, it is assumed that unreasonable edge data occurs
At Img [a, b, 3], then following formula can be used and handled:
Img [a, b, 3]=(Img [a-1, b, 3]+Img [a+1, b, 3]+Img [a, b+1,3]+Img [a, b-1,3])/4,
To obtain the corresponding reasonable edge data of column range.
After the column range for obtaining edge data by the above method, and carried out according to the related algorithm of image synthesis
Change processing, finally obtains the complete monitoring image of a frame as shown in Figure 8.The pixel-matrix data of this frame image synthesized at this time
For Img [m, 2n-p, 3], wherein p is the column range of edge data, and the pixel-matrix data of the edge image are m row p
Column, it may be assumed that Brim [m, p, 3].
Certainly, in practical applications, edge data can also be handled by other methods such as interpolation, herein
Without limitation.
In this way, after the synthesis complete monitoring image of one frame, as shown in figure 9, it is complete to repeat above-mentioned one frame of synthesis
The step of monitoring image, is finally completed the office of the different moments to the acquisition of each video camera to synthesize to multiframe monitoring image
The synthesis of portion's monitoring image.
After the monitoring image synthesized, generally, as shown in Figure 10, it is also necessary to synchronizing of monitoring image place
Reason.Assuming that monitoring image is synthesized to obtain by the local monitoring image that n video camera is shot, the part prison of first video camera shooting
The vector for controlling image data is f1 (t), and the vector of the local monitoring image data of second video camera shooting is f2 (t), successively
Analogize, then the vector f (t) of the monitoring image data of available synthesis=f1 (t)+f2 (t))+...+fn (t).F (t) is contained
Line information selects suitable synchronised clock so as to carry out calculating line frequency size according to 25 frames are per second according to the size of f (t)
It is monitored image data output.It is of course also possible to be carried out selecting different output formats according to different displays, do not limit herein
It is fixed.
