Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the present invention is described further, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
It please refers to shown in Fig. 1 and 2, a kind of zero piece liquid crystal of the integrated pixel filling based on HDbaseT signal transmissions
Mosaic screen comprising multiple splicing screens 2, processor 1 and HDbaseT input interfaces 3；Wherein, the HDbaseT inputs connect
Mouth 3 passes through processor 1 and the multiple splicing screen 2 is electrically connected.Splicing screen 2 is all made of liquid crystal display, passes through
External image or/and video etc. are transmitted on splicing screen 2 and show by HDbaseT input interfaces 3, in order to reach pixel
The display effect of filling integration and zero piece, in preferred embodiments of the present invention, by processor 1 to the figure of transmission
Picture or/and video are handled, and video is that the combination of multiple images is explained and illustrated here only by taking image transmitting as an example.
Processor 1 includes image mosaic processing system, which includes：Image pre-processing module 10,
Piece definition module 20 and piece cancellation module 30.Wherein：
Image pre-processing module 10 is for pre-processing image, to adapt to corresponding splicing screen；Image preprocessing mould
Block includes image telescopic unit 11, and described image telescopic unit 11 carries out flexible change by formula y=Asin ω x to multiple images
It changes, wherein A is the flexible multiple of image on the vertical scale, and ω is the flexible multiple of image on the horizontal scale, so that each image
Corresponding splicing sub- screen is adapted.Being adapted here, is mainly reflected in：Pass through image telescopic unit treated image
Outer edge extend to the first setpoint distance L in contiguous concatenation screen, as shown in Figure 3, it is assumed that first splicing son screen 21 and second
Splicing son screen is 22 adjacent, the two there are gap 23 (in figure gap 23 be in order to characterize between it is present in two splicing son screens, it is true
Upper gap 23 is very small in itself, is similar to ignore)；So, the image 211 in the first splicing screen 21 finishes flexible processing
Side (shielding 22 opposite sides with the second splicing) afterwards extends into the second splicing screen 22, extends to the second splicing
The width of screen 22 is L (if it is two splicing son screens of upper and lower directions splicing, then the height extended is L), and similarly, second spells
It is also L to connect the image 221 in sub- screen 22 and finish the width extended into the first splicing screen 21 after flexible processing.
Piece definition module 20 is defined for the piece between adjacent image；Definition to piece is with adjacent spelling
Centered on connecing the gap between sub- screen, to the left and right sides or upper and lower both sides are diffused, and the region after diffusion constitutes piece, diffusion
Length be the first setpoint distance, i.e., shown in Fig. 3, the piece that constitutes between the first splicing screen 21 and the second splicing screen 22
For the region between dotted line in figure.
Piece cancellation module 30 is eliminated for the piece to definition, so that the image of edge joint position and other regions
Image is adapted.So-called elimination is in the intuitive observation of people there is no lofty, therefore, by gray proces method to piece
Interior gray scale is handled, steady excessive with the image in other regions to achieve the purpose that.Here other regions refer to except spelling
Region in the outer splicing screen of seam.
Further, piece cancellation module 30, including：
Cell division unit 31 carries out edge joint position the division of piece cell, meanwhile, to other areas in splicing son screen
The image in domain carries out the division of elementary area lattice；Piece cell is smaller, and image procossing is also more accurate, for other regions
Image preferably only carries out elementary area lattice division to the image close to piece periphery, and specific range is according to actual needs
It defines.
Gray scale acquiring unit 32, the gray value for obtaining the piece cell and elementary area lattice；Gray value is face
Color depth is binary value, can be obtained by softwares such as matlab.
Piece processing unit 33, for carrying out weight to the gray scale of piece cell according to the gray value of described image cell
It generates, obtains the panoramic picture for being finally shown in splicing son screen.
Further, the detailed process of piece processing unit 33 includes：
First subelement 331 is inquired and obtains target piece cell adjacent piece cell or/and elementary area
Lattice, so-called target piece cell will carry out the piece cell of gray proces, herein mainly with other piece cells
It distinguishes.When gray proces, the piece cell preferably gone out with a piece wherein vertex starts, from wherein side gradually to another
Side carries out gray processing processing, if since middle part, due to its periphery piece cell gray value there is also error,
Handling result that then may be final is inaccurate.
Second subelement 332 sets target piece cell and its adjacent piece cell or/and elementary area lattice
It sets corresponding weighted value, target piece cell and its adjacent piece cell or/and the setting of elementary area lattice is corresponding
The sum of weighted value is equal to 1.The purpose for increasing weighted value is other piece cells on target piece cell periphery, especially for
The piece cell of gray proces is carried out, the proportion occupied should be smaller, and weighted value is relatively small, and gray proces
Piece cell and the proportion that occupies of elementary area lattice should be larger, weighted value is relatively large, and exception also needs to refer to
Specific color regime carries out.
Third subelement 333, according to target piece cell and its adjacent piece cell or/and elementary area lattice
Corresponding gray value and corresponding weighted value obtain average gray, and the gray value of piece cell is with the face after image superposition
The gray value of color is as its gray value.
4th subelement 334 adjusts the gray scale of target piece cell according to the average gray, i.e., gray scale is averaged
It is worth the gray scale of target piece cell, to achieve the purpose that gray scale adjusts.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
