Abstract

The invention relates to the technical field of panoramic image splicing, in particular to a panoramic image splicing method, which comprises the following steps: S1, carrying out basic operation of digital image processing, establishing a matching template of an image, and carrying out Fourier transform and wavelet transform on the image; s2, using a certain matching strategy to find out corresponding positions of templates or feature points in the images to be spliced in the reference image, and then determining the transformation relation between the two images; s3, calculating each parameter value in the mathematical model according to the corresponding relationship between the template or the image features, thereby establishing a mathematical transformation model of the two images; s4, converting the images to be spliced into a coordinate system of the reference image according to the established mathematical conversion model, and completing unified coordinate conversion; and S5,fusing the overlapped areas of the images to be spliced to obtain a spliced and reconstructed smooth seamless panoramic image. According to the invention, misplaced splicing fusion of the images canbe realized, so that the splicing error of the images is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of panoramic image stitching, in particular to a panoramic image stitching method. Background technique [0002] Image stitching technology is the technology of stitching several overlapping images (which may be obtained at different times, different viewing angles or different sensors) into a large seamless high-resolution image. When using an ordinary camera to capture a scene image with a wide field of view, because the resolution of the camera is fixed, the larger the scene is, the lower the resolution of the image will be; while the panoramic camera and wide-angle lens are not only very expensive, but also have serious distortion. In order to obtain an ultra-wide viewing angle or even a 360° panorama without reducing the image resolution, the use of computer image mosaic was proposed and gradually researched and developed. [0003] In the prior art, the image registration technology mainly adopts the p...
