Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0046] figure 1 The structure of the image mosaic system in this embodiment is shown. Such as figure 1 As shown, the system includes a first selection device 11, a second adjustment device 16 connected with the first selection device 11, a second selection device 12 connected with the second adjustment device 16, and a splicing device connected with the second selection device 12 13 , the first adjusting device 14 connected to the splicing device 13 , and the cutting device 15 connected to the first adjusting device 14 .

[0047] The first selecting device 11 is used for selecting several groups of relative points on the same pattern from the first image and the second image to be stitched.

[0048] The second adjustment device 16 is used to judge whether the relative point selected from the second image is suitable with reference to the selec...

Abstract

The invention relates to an image splicing method and an image splicing system, which belong to the technical field of image processing. The method comprises the steps of: firstly selecting M groups of relative points from overlapped parts of a first image and a second image to be spliced, and selecting two groups of relative points from all groups of relative points as splicing reference points; then splicing the images by taking the splicing reference points as references; adjusting non-overlapped points in the overlapped parts of the spliced images; and finally cutting the overlapped parts of the spliced images. The image splicing method and the image splicing system have the advantages that the seamless splicing of a plurality of pairs of reference points can be supported, a user is only required to select the relative points, the operation is simple and the splicing effect is good.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image splicing method and system. Background technique [0002] Image stitching refers to the technology of seamlessly splicing two or more overlapping images into one larger image. Image registration and image fusion are two key technologies of image stitching. Image registration is the basis of image fusion, and the calculation of image registration algorithms is generally very large, so the development of image mosaic technology largely depends on the innovation of image registration technology. Early image registration techniques mainly used point matching methods, which were slow in speed and low in precision, and often required manual selection of initial matching points, which could not adapt to the fusion of images with large amounts of data.
