Usually, the effect of display monitoring image detail is reached, needs can physically gather enough data.
Then, propose in monitoring display method provided in an embodiment of the present invention it is constant in photosensitive region resolution ratio under conditions of, lead to
Cross increase video camera quantity come reach improve monitoring image resolution ratio effect.For example, as shown in Figure 2 a, it is assumed that complementary gold
Category oxide semiconductor Complementary Metal Oxide Semiconductor, CMOS) photosensitive region resolution ratio
The display resolution of the monitoring image shot for 960*540, correspondence is 960*540.It is now to the display of monitoring image point
Resolution reaches 1920*1080, as shown in Figure 2 b, then needs to select four identical video cameras, and monitoring image is divided into four
Individually shooting is responsible for by a video camera in individual region, each region.Then by the local monitoring figure of four video camera correspondence collections
As being synthesized, so as to obtain the monitoring image that resolution ratio is 1920*1080.Certainly, in practical application, can be based on same

Specifically, for the resolution ratio of the monitoring image of display needed for determining, in above-mentioned prison provided in an embodiment of the present invention
In control display methods, in the specific embodiment of step S101 it is determined that required display monitoring image resolution ratio with it is current aobvious
Before the resolution ratio difference of the monitoring image for showing, can also comprise the following steps：
Receive the scalability information to currently displaying monitoring image；
According to the resolution ratio of currently displaying monitoring image, and the scalability information of currently displaying monitoring image, it is determined that
The resolution ratio of the monitoring image of required display.
Further, in order to realize man-machine interaction, in above-mentioned monitoring display method provided in an embodiment of the present invention, step
The scalability information to currently displaying monitoring image is received, specifically can be accomplished by：
The scalability information of the currently displaying monitoring image that touch control unit sends is received, i.e. user can pass through touch control unit
Send the scalability information with regard to currently displaying monitoring image.Additionally, user can also be optionally monitored by mouse
The scaling of image, here is not limited.
Specifically, due to after the local monitoring image for gathering corresponding monitoring range respectively in each video camera, unavoidably
Can there is a problem of edge data, therefore, in above-mentioned monitoring display method provided in an embodiment of the present invention, step S102
The corresponding monitoring image of local monitoring image synthesis monitor area of the middle corresponding monitoring range for photographing in each video camera, tool
Body can be accomplished by：
The local monitoring image of the corresponding monitoring range shot according to two adjacent video cameras, determines adjacent two
Edge data between the local monitoring image that video camera is generated；
Edge data to determining is entered after row interpolation or homogenizing process, and with local monitoring image synthesis monitoring is carried out
The corresponding monitoring image in region.
For example as shown in figure 4, illustrating so that two video cameras shoot monitor area as an example.Two are respectively shown in Fig. 4
The stacking chart of the local monitoring image of individual video camera correspondence collection：Wherein, oblique line portion is the edge image of superposition.Also, such as
Shown in Fig. 5, video camera can rationally carry out internal focus using micro control system, and debugging focus point is carried out in depth of field controlled range
Position, so as to obtain clearly local monitoring image.
Assume two video cameras some collection moment, correspondence collection a frame local monitoring image pixel-matrix with
RGB modes are stored, as shown in Figure 6.In Fig. 6 shown in the left side, be one of camera acquisition pixel-matrix data Img1 [m,
N, 3], it is corresponding pixel-matrix data Img2 [m, n, 3] of another video camera in Fig. 6 shown in the right, wherein, m represents line number
According to n represents column data, and 3 represent RGB three-dimensional components.For the sake of simplicity, the identification of edge data is carried out by taking R matrixes as an example
And process.R component data are compared according to R1 [m, n] and R2 [m, n], so as to obtain the row model of edge data
Enclose.
Specifically, the row scope of edge data can be obtained according to method as shown in Figure 7, i.e., according to process function F
X whether () judges successively the space length of each column data of each row between R pixel-matrix data R1 [m, n] and R2 [m, n] in experience
In value interval (- δ ,+δ), and then judge row scope p of edge data.It should be noted that the process shown in Fig. 7
Journey is most full processing mode, in actual applications, can be according to the valued space of the pixel-matrix data of monitoring image, pressing
According to most simplified processing mode, for example, 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, so as to quickly obtain p value.
Further, after the row scope for obtaining edge data, in addition it is also necessary to the edge data in the range of row
Reasonability judged, and irrational edge data is processed.For example, it is assumed that pixel-matrix data are four
Storage, when a frame data are obtained, the edge data that video camera shoots be array a=0101,0000,0011,
1100 }, { 0000,0011,0010,0000 }, { 1111,1010,1101,0010 } }, the edge image that another video camera shoots
Data be array b={ 0001,0010,0010,1100 }, { 0000,0011,0010,0000 }, 1001,1011,0011,
0101 } }, according to an expression Δ s=Σ (a for processing function F (x)2-b2), in calculating the space length of two groups of data
Most short space length whether in the range of | δ |, so as to judge the span of edge data.If most short space away from
From not interior in interval | δ |, it is determined that the corresponding edge data of the most short space length is unreasonable.For these do not conform to individually
The edge data of reason, here is processed for convenience, can according to irrational edge data and its before and after two rows,
The correlation of the edge data of upper and lower two row, is smoothed.For example, it is assumed that irrational edge data occurs
At Img [a, b, 3] place, then can be processed using equation below:
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,
So as to obtain the corresponding rational edge data of row scope.
Obtained after the row scope of edge data by said method, and carried out according to the related algorithm of image synthesis
Change is processed, and finally gives the complete monitoring image of a frame as shown in Figure 8.The pixel-matrix data of this two field picture for now synthesizing
For Img [m, 2n-p, 3], wherein, p for edge data row scope, the pixel-matrix data of the edge image are m row p
Row, i.e.,：Brim[m,p,3].
Certainly, in actual applications, edge data can also be processed by additive methods such as interpolation, here
Do not limit.
Thus, after the complete monitoring image of one frame of synthesis, as shown in figure 9, it is complete to repeat the frame of above-mentioned synthesis one
The step of monitoring image, to synthesize to multiframe monitoring image, it is finally completed the office not in the same time to each camera acquisition
The synthesis of portion's monitoring image.
After the monitoring image for synthesizing is obtained, usually, as shown in Figure 10, in addition it is also necessary to synchronizing of monitoring image place
Reason.Assume that monitoring image is synthesized by the local monitoring image that n video camera shoots to obtain, the local prison that first video camera shoots
The vector of control view data is f1 (t), and the vector of the local monitoring image data of second video camera shooting is f2 (t), successively
Analogize, then can obtain vector f (t)=f1 (the t)+f2 (t) of the monitoring image data of synthesis)+...+fn (t).F (t) is contained
Line information, so as to carry out calculating line frequency size according to 25 frames are per second according to the size of f (t), selects suitable synchronised clock
It is monitored view data output.It is of course also possible to be carried out selecting different output formats, here not to limit according to different displays
It is fixed.
