Abstract

The invention provides a panoramic image generation method and device, and the method comprises the steps: obtaining a first type of edge seed points and a second type of edge seed points of an overlapping region of a deformation image and a reference image; taking one pixel of the upper edge of an image formed by the second type of edge seed points as the start point of a to-be-selected suture line, and taking one pixel of the lower edge of an image formed by the first type of edge seed points as the end point of the to-be-selected suture line, wherein each to-be-selected suture line starts to pass through the overlapping region continuously from the start point to the end point; carrying out the traversal of all possible to-be-selected suture lines; determining the to-be-selected suture line with the minimum weight value as the optimal suture line, wherein the determined optimal suture line is more reasonable, thereby reducing the figure deformation, joint misplacing and apparent joint traces, and improving the effect of a generated panoramic image.

Description

technical field [0001] Embodiments of the present invention relate to image processing technology, and in particular, to a method and device for generating a panoramic image. Background technique [0002] With the rapid development of science and technology, electronic devices have more and more functions. For example, the camera on a mobile phone can provide a panoramic photo function. [0003] When people travel, they encounter large scenes such as beautiful mountains, rivers, grasslands, lakes, seas of flowers, or magnificent buildings and squares. The camera or mobile phone lens is often not enough to capture the complete scene. At this time, Using panorama technology to stitch multiple narrow-angle images into one panorama image. In the prior art, when using the splicing module in the open source computer vision class library "Opencv" to splice the images of different viewing angles taken, an image registration method (Speeded Up Robust Features (Speeded Up Robust Feat...
