Embodiment Construction

[0029] An image splicing method, the specific steps are:

[0030] Step (1). Select the coarse registration area: For image A and image B to be stitched, set the The area is used as the initial area of ​​image A, and the area in image B close to image A is used as the initial area of ​​image B, =3~5;

[0031] The image A and the image B are both rectangular images, the initial area of ​​the image A and the initial area of ​​the image B are both rectangular areas, one edge of the image A is an edge of the initial area of ​​the image A, and one edge of the image B is an image An edge of the initial area of ​​B;

[0032] Step (2). The pixel values ​​at each overlapping coordinates of the initial region of image A and the initial region of image B are weighted averaged in pairs to obtain image C for subsequent use;

[0033] Step (3). Grayscale the image C, and then calculate the energy value of each pixel in the image C

[0034] , is the coordinates of the pixel point;

[...

Abstract

The invention relates to an image stitching method. A traditional image stitching method is not good in effect. The image stitching method includes the steps: firstly, selecting a coarse registration area and carrying out pairwise weighted average on pixel values at the positions of overlapping coordinates of initial areas of two images, obtaining a reserved image, then, scanning an energy matrix of the reserved image line by line, obtaining a minimum energy line after calculation, obtaining a strip-shaped area by serving the minimum energy line to as a center to expand to two sides, respectively finding corresponding registration areas from the initial areas of the two images, carrying out image fusion on all the pixel values in the registration area of the two images to obtain a stitching area, and then finishing image stitching. According to the image stitching method, not only can an optimal matching seam be found rapidly, but also selection of an image fusion area can be reduced, and an optimized stitching image can be obtained.

Description

technical field [0001] The invention belongs to the technical field of image data processing, and in particular relates to an image splicing method. Background technique [0002] With the development of computer technology, digital storage of various information has become very common. Among all kinds of information, text and image information are used the most. However, as people's requirements for image quality and precision are getting higher and higher, image stitching, as an important branch of image processing technology, has become a hot issue in the fields of multimedia, medical image processing and computer graphics. The problem of image stitching can be defined as forming a seamless, high-definition image with higher resolution and larger field of view than a single image by aligning a series of spatially overlapping images. [0003] Early image stitching research has been used in photogrammetry, mainly integrating a large number of aerial or satellite images. I...
