Abstract

The invention provides an image stitching method, an image stitching device, electronic equipment and a computer readable storage medium. The image stitching method comprises the steps that an image sequence obtained through continuous shooting is acquired; a motion target in the image sequence under a dynamic background is detected based on an optical flow method; a first image and a second imageto be stitched are extracted from the image sequence; image processing is performed on the first image and the second image to obtain a first processed image and a second processed image, wherein image processing comprises image registration; and based on the detection result, image fusion is performed on the first processed image and the second processed image to obtain an image after stitching.The technical scheme is beneficial for improving the elimination effect of ghost.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image stitching method, an image stitching device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Panoramic image acquisition is an emerging research field and hot topic in computer vision. At present, panoramic images are obtained mainly through the following two methods: 1. Directly use special wide-angle imaging equipment (such as non-linear optical imaging equipment such as fisheye optical lens and convex reflective optical lens) to capture images with a large enough horizontal angle at one time, but Its cost is high, and the resolution and viewing angle are difficult to balance, and the image will be seriously distorted; 2. Through image stitching technology, a group of low-resolution or small viewing angle images with overlapping areas are stitched into a high-resolution, wide-view image new ima...
