Problems solved by technology

[0007] Chris proposed the Harris interest point detection algorithm. This method realizes that the extracted feature points are invariant to translation and rotation, and has good robustness to parameter changes, noise, image changes, and illumination transformations. However, the disadvantages are I...

Abstract

The invention discloses a template-based Poisson fusion image splicing method, system and device, and a medium, and the method comprises the steps: obtaining two to-be-spliced images, and carrying outthe feature point extraction of each to-be-spliced image; performing feature point matching on one to-be-spliced image and the other to-be-spliced image by using a particle swarm algorithm; finding an overlapping region for one to-be-spliced image and another to-be-spliced image; finding an optimal suture line in each overlapping region based on the gray value and a graph cut algorithm; creatinga template based on the optimal suture line; and based on the template and a Poisson fusion algorithm, splicing the to-be-spliced images to obtain a panoramic image.Splicing of multiple images can bebetter realized, and the problems of ghosting and gaps in a splicing result are effectively solved.

Description

technical field [0001] The present disclosure relates to the technical fields of image processing and computer vision, in particular to a template-based Poisson fusion image mosaic method, system, device and medium. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] In the process of realizing the present disclosure, the inventors found that the following technical problems existed in the prior art: [0004] Image stitching technology is an important research direction of computer vision. Since the viewing angle of most cameras and monitoring equipment is relatively narrow, panoramic images are very important and can display a wide range of environmental views. The emergence and development of stitching technology provides an effective solution for obtaining wider viewing angles, higher resolution and panoramic images, and has been widely used in v...
