Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
A kind of image edge fusion projection method of one embodiment, including：
Image segmentating device divides the image into some regular figures, and some regular figures are filled by different image projections respectively
Put and projected；Wherein, it is divided into the overlapped figure in adjacent pattern edge after some regular figures and appears in segmentation at the same time
The edge of adjacent pattern afterwards；Crisscross ordinate, horizontal line are arranged on the entire image；Different image projection devices will divide
Some regular figures after cutting are projected, and adjusting image projection device makes indulging in the overlapped figure in adjacent pattern edge
Line, horizontal line are completely overlapped so that the picture material of lap is completely the same.
For lap, the present embodiment carries out Homogenization Treatments using the brightness that electron gain is adjusted to overlay region.Electricity
Sub- gain is by adjusting the side for changing each adjacent image overlapping region in image processing module and only having same image content
The gain of each pixel in edge region or pixel set will change its brightness, brightness of the image in overlapping region is reached uniformly mistake
Degree.The effect of electron gain reaches to form quarter circular arc blend curve, and Fusion Edges are carried out to overlay region.Show for light leak
As the luminance compensation method using classification with reference to linear gradient.
Another embodiment, as shown in Fig. 2, a kind of image edge-blending processing system, including：
Image segmentation module, point processing such as carries out image；
Geometric correction of imagery module, to image overlapping region image rectification and makes the picture material in the region consistent；
Color consistency processing module, the color of more than two images is adjusted to consistent；
Image conformity adjusts module, and brightness and color uniformity to image are adjusted；
Fusion band processing module, image cutting and picture brightness gradual change are carried out to the fusion band between more than two images
Processing.
Details in a play not acted out on stage, but told through dialogues brightness repair process module, the brightness in the non-overlapped area in the case of adjusting details in a play not acted out on stage, but told through dialogues are allowed to and overlay region brightness one
Cause.
The processing procedure of one embodiment, first respectively shoots every projector with high-resolution video camera (position is constant)
Preliminary treatment is carried out Deng the horizontal line and vertical line, complete white picture and overall Background of sub-screen, and to image.Using camera mapping tree
Method carry out geometric correction, obtain every projector geometric correction matrix.
In color consistency processing module, the projector image merged by third party signalling source to needs all inputs respectively
Red, green, blueness, cyan, yellow, purple and white picture, then sample, and host computer uses RGB color domain space to calculate
Standard meter calculates the required RGB penalty coefficients of image.Wherein, third party signalling source can be the signal source that user uses, bag
Include PC and reference signal generator etc.；Host computer can be upper level control device, be usually PC machine, mobile phone or PAD etc..Color
Using red, green, blueness, cyan, yellow, purple and white, totally seven colors carry out independent adjustment processing to consistency treatment module,
The color of each is all divided into the combination of a certain kind or certain several color in seven colors, then by computing, ensures various mixing
The uniformity of color color.Color consistency processing module is more than two projectors in image edge-blending processing system
Color be adjusted to consistent.The value of each pixel of the image of this example preferably first resolves into white module, complementary color module and primary colours
Module, matches with the colour gamut of RGB patterns, and this example uses seven color consistency algorithms.Wherein, the penalty coefficient that host computer provides,
The image of the projecting apparatus merged to needs all inputs red, green, blueness, cyan, yellow, purple and white picture respectively, so
Afterwards by manually or using camera device sampling and calculate penalty coefficient, that is, calculate color that each picture included with it is defeated
Enter the difference between picture color, to ensure that seven colors are consistent above.Therefore, white module is a numerical value；Complementary color module
Penalty coefficient has three, but actual used time, and one is only selected in three；The penalty coefficient of primary colours module also has three, but real
The border used time, only selects one in three.It is described to be sampled by artificial or use camera device and calculate the mistake of penalty coefficient
Cheng Wei：Artificial sample, is exactly that the picture for seeing projector is observed in operator's employment, and the sensation such as brightness projector and color is led to
Cross the digital quantization of 0-100 and be input in upper computer software, wherein, perceived brightness is highest to be set to 100, and others are corresponding
Reduce numerical value.Camera device samples, and exactly projector's screen shot is photographed by settings such as CCD, host computer is in picture
Pixel calculated with RGB color domain space, the rgb value of the pixel of picture (i.e. projected picture) center section averaged；This
The each picture of sample only has a value；The value of all pictures is compared, be worth maximum is set to 100, the value of other pictures, according to
Gradually reduced with the difference of maximum picture.The computational methods of the penalty coefficient：In the value for the 0-100 that sample above obtains
In, the value of more all pictures, using minimum value as target, each picture is individually subtracted is worth to difference, the difference that will be obtained
Again divided by 100, penalty coefficient is just obtained.For example, Liang Ge projectors A, B, it is not A that their red values, which are,：100、B：
90.Therefore, desired value is 90, so, the penalty coefficient of A is：90-100=10,10 difference to obtain, then passes through 10/ again
100=0.1 that is, penalty coefficient is 0.1.
Image conformity adjusts a preferred embodiment of module, and picture is divided into D block of pixels, the size of each block of pixels
It is B*C pixel；Then the weighting coefficient a of each pixel is calculated, the uniformity of image is adjusted by weighting coefficient a；Its
In, weighting coefficient a is the array matrix coefficient of a B*C, and in B*C pixel, the weighting coefficient of the pixel A in centre position is
I, centered on pixel A, the weighting coefficient of the pixel on side is successively decreased with stepping S, then can calculate each by a=I-S
The weighting coefficient a of pixel, finally obtains a brightness and the extraordinary picture of color uniformity.Described B, C and D are nature
Number, the stepping S can be obtained by Image Acquisition and pixel analysis.
Another preferred embodiment, carries out Fusion Edges, as Fig. 1 shows overlay region using quarter circular arc to overlay region
The blend curve in domain, by taking the adjacent projector in left and right as an example, its alpha value is changed in strict accordance with quarter circular arc, will
The scaled of overlapping region is between 0 to 1, and the value of the alpha of both sides projecting apparatus is in strict accordance with quarter circular arc curve
It is sliding.
For light leakage phenomena, an embodiment as shown in Figure 3 employs luminance compensation method.Since light leak is in physical layer
Can not eliminate, so be merely able to increase the brightness in non-overlapped area, the brightness of a weight, double, triple overlay region, be allowed to it is four heavy
Folded area's brightness is equal.For overlay region, it would be desirable to the accurate size for knowing overlapping region.Mended for different artworks
The brightness repaid is methods that are different, then employing grading compensation.
What each embodiment stressed is all the difference with other embodiments in this specification, each embodiment it
Between identical similar portion cross-reference.
