Abstract

The invention relates to the technical field of image processing, and provides an image splicing method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring a first image and a second image; according to the first image and the second image, obtaining a first intermediate optical flow and a second intermediate optical flow through calculation, wherein the first intermediate optical flow is an optical flow between the intermediate image and the first image, the second intermediate optical flow is an optical flow between the intermediate image and the second image, the intermediate image is an image of which the visual angle is between the visual angle of the first image and the visual angle of the second image, the size of the first intermediate optical flow is the same as that of the first image, and the size of the second intermediate optical flow is the same as that of the second image; and calculating a spliced image of the first image and the second image according to the first intermediate optical flow, the second intermediate optical flow, the first image and the second image. According to the image splicing method, the image splicing can be completed without calculating a plurality of homography matrixes through complex iteration, so that the image splicing efficiency can be improved.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, relates to an image stitching method and device, a storage medium, and electronic equipment. Background technique [0002] Image stitching can refer to the process of stitching together multiple images with overlapping areas to obtain a seamless panoramic image. In recent years, image stitching technology has been widely used in aerospace, medical minimally invasive surgery, medical microscopic observation and geological survey and other fields. [0003] In the prior art, image stitching can be realized by camera calibration, but this kind of method has a large amount of calculation and needs to iteratively calculate multiple homography matrices, making the stitching process inefficient. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide an image stitching method and device, a storage medium, and an electronic ...
