The image to be processed specifically refers to a complete image that needs to be displayed on four display screens, that is, a partial image in the image to be processed is displayed on each display screen, and the four display screens are combined to display the complete image of the image to be processed.
The maximum values of the vertical coordinates of the first pixel area and the second pixel area are different from each other by a first preset value, the maximum values of the horizontal coordinates of the first pixel area and the third pixel area are different from each other by a second preset value, and the first pixel area and the fourth pixel area are centrosymmetric.
Taking fig. 2B as an example, fig. 2B is a schematic diagram of each image to be fused in the image processing method of the present invention, wherein the enlargement process is performed by taking 1: the example 1 is illustrated, that is, the pixel regions are equal to the corresponding to-be-fused images, where the first pixel region is a region corresponding to the first to-be-fused image a in fig. 2B, the second pixel region is a region corresponding to the second to-be-fused image B in fig. 2B, the third pixel region is a region corresponding to the third to-be-fused image C in fig. 2B, the fourth pixel region is a region corresponding to the fourth to-be-fused image DC in fig. 2B, fig. 2B is only used to describe the relationship among the first pixel region, the second pixel region, the third pixel region, and the fourth pixel region, and fig. 2B does not show the specific positions of the pixel regions. Taking the horizontal direction as an abscissa axis, the abscissa axis increasing from left to right, taking the vertical direction as an ordinate axis, the ordinate axis increasing from top to bottom, as shown in fig. 2B, the maximum values of the ordinate of the first pixel region and the second pixel region differ by a first preset value, the maximum values of the abscissa of the first pixel region and the third pixel region differ by a second preset value, and the first pixel region and the fourth pixel region are centrosymmetric.
In this embodiment, an image of a corresponding area of the image to be processed is captured according to the first pixel area, the second pixel area, the third pixel area, and the fourth pixel area, and then an enlargement process is performed to obtain the first image to be fused, the second image to be fused, the third image to be fused, and the fourth image to be fused, where the enlargement process is to enlarge the captured image to the same size as the display screen.
The first image to be fused, the second image to be fused, the third image to be fused and the fourth image to be fused all comprise a fusion area, the fusion area of the first image to be fused is asymmetric with the fusion area of the second image to be fused and the fusion area of the fourth image to be fused, and the fusion area of the third image to be fused is asymmetric with the fusion area of the second image to be fused and the fusion area of the fourth image to be fused.
The "fusion region" referred to herein specifically refers to a region of one image that overlaps another image, for example, the fusion region of the first image to be fused specifically refers to a region where the first image to be fused overlaps a fourth image to be fused, the fusion region of the second image to be fused specifically refers to a region where the second image to be fused overlaps the first image to be fused, the fusion region of the third image to be fused specifically refers to a region where the third image to be fused overlaps the second image to be fused, and the fusion region of the fourth image to be fused specifically refers to a region where the fourth image to be fused overlaps the third image to be fused.
And 102, performing fusion processing on the first image to be fused, the second image to be fused, the third image to be fused and the fourth image to be fused, acquiring a first image to be output, a second image to be output, a third image to be output and the fourth image to be output, and outputting the first image to be output, the second image to be output, the third image to be output and the fourth image to be output to corresponding display screens respectively.
Because the first image to be fused, the second image to be fused, the third image to be fused and the fourth image to be fused all comprise a fusion area, image quality processing needs to be carried out on each fusion area, so that the images output to each display screen are spliced to form a whole image which is free of gaps and clear in image quality.
In this embodiment, an image to be processed is intercepted and amplified according to a first pixel area, a second pixel area, a third pixel area and a fourth pixel area, so as to obtain a first image to be fused, a second image to be fused, a third image to be fused and a fourth image to be fused, the first image to be fused, the second image to be fused, the third image to be fused and the fourth image to be fused are fused, so as to obtain a first image to be output, a second image to be output, a third image to be output and the fourth image to be output, and the first image to be output, the second image to be output, the third image to be output and the fourth image to be output are output to corresponding display screens respectively. The maximum values of the vertical coordinates of the first pixel area and the second pixel area for intercepting the images to be fused are different by a first preset value, and the maximum values of the horizontal coordinates of the first pixel area and the third pixel area are different by a second preset value, so that the fusion areas of the adjacent images to be fused are asymmetric, the fusion splicing of a plurality of images can be realized, and the calculation resources required by the fusion splicing can be reduced.
Explaining further the reduction of the computational resources required for fusion and splicing, fig. 3A is a schematic diagram of images to be fused in the prior art during fusion and splicing, fig. 3B is a schematic diagram of splicing the images to be fused shown in fig. 3A, each image to be fused obtained by intercepting and amplifying in the prior art during fusion and splicing is shown in fig. 3A, A, B, C and D are respectively an image to be fused, two sides of each image to be fused are fusion areas, as shown in fig. 3A, the fusion areas of adjacent images to be fused are symmetrical, when A, B, C and D are spliced together, image quality processing needs to be performed on an intermediate overlapping area as shown in fig. 3B, after A, B, C and D are spliced together, an 1/4 area appears, and the 1/4 area is formed by overlapping the fusion areas of A, B, C and D together, in the image quality processing of the 1/4 region, it is necessary to determine the image information of the fusion region of the integrated A, B, C and D, that is, in the case of the solution fusion processing of the related art, it is necessary to perform the image quality processing of not only the image quality processing of each fusion region as shown in fig. 3B but also the image information of the fusion region of the integrated A, B, C and D on the 1/4 region, which increases the computational resources.
Compared with the prior art, after the images to be fused are spliced together, the 1/4 area does not exist in image quality processing, so that the computing resources required by fusion splicing can be reduced. The reason why the 1/4 region does not exist is that the first pixel region, the second pixel region, the third pixel region, and the fourth pixel region of the image to be fused are cut out in such a manner that the fusion regions of the adjacent images to be fused are asymmetric.
The following describes in detail the technical solution of the embodiment of the method shown in fig. 2, using several specific embodiments.
