Problems solved by technology

However, due to the image taken by the commonly used rotating camera, the arc distortion after fusion is relatively serious, and the current image stitching technology only corrects the optical lens distortion after image fusion, and does not correct the arc distortion, resulting in The image of the image does not look good

Abstract

The present invention relates to an image stitching method and apparatus. The method comprises: obtaining a plurality of images continuously shot by a rotary camera; determining two adjacent images of a to-be-stitched image in the plurality of images, wherein the adjacent images are two overlapped images in the shooting space; carrying out image registration on the adjacent images so as to obtain a transformation matrix of the adjacent images; carrying out image fusion on the adjacent images according to the transformation matrix so as to obtain a mosaic image; and carrying out arc distortion correction on the mosaic image so as to obtain a panoramic image. According to the image stitching method provided by embodiments of the present invention, for the obtained images that are continuously shot by the rotary camera, adjacent images of the to-be-stitched image are determined, image registration and image fusion are carried out on the adjacent images so as to obtain the mosaic image, and arc distortion correction is carried on the mosaic image, so that the obtained panoramic image has no arc distortion, but has good visual effects.

Description

technical field [0001] The present invention relates to the technical field of image stitching, in particular to an image stitching method and device. Background technique [0002] Image stitching technology is an increasingly popular research field, which has become a hot spot in photogrammetry, computer vision, image processing and computer graphics research. A series of spatially overlapping images are processed through image stitching technology to form a seamless, high-definition image. The stitched image has a higher resolution and a larger field of view than a single image. [0003] Image stitching technology has been applied in many fields. In the night vision imaging technology in the military field, both night vision low-light and infrared imaging equipment cannot take pictures with a wide field of view due to the limitation of camera equipment. Using image stitching technology, after analyzing the conditions of the shooting equipment and the surrounding scenery, ...
