Abstract

The invention discloses a minimum spanning tree-based mosaic method for panoramic images taken by a mobile phone, which comprises the following steps: tracking and collecting images: the user acquires several images of the panoramic photos to be taken according to the camera tracking guide; image matching: using the matching between images Relation constructs the relational graph structure between images; establishes the minimum spanning tree: establishes the corresponding minimum spanning tree according to the relational graph structure in image matching; image stitching: takes the image corresponding to the root node of the minimum spanning tree as the canvas plane of the final puzzle, The path from the root node to each node is used to generate the perspective transformation from each image to the canvas plane. The invention has a reasonable design, simplifies the complex procedures in the process of taking pictures, can achieve good image stitching effects, and can effectively alleviate the final puzzle The distortion caused by the medium perspective transformation greatly improves the image stitching effect.

Description

technical field [0001] The invention relates to the technical field of image stitching, in particular to a method for stitching panoramic images taken by mobile phones based on a minimum spanning tree. Background technique [0002] Image stitching technology is the technology of stitching several overlapping images (which may be obtained at different times, different perspectives or different sensors) into a seamless panorama or high-resolution image. Image registration and image fusion are two key technologies of image stitching. Image registration is the basis of image fusion, and image registration algorithms generally require a large amount of computation, so the development of image mosaic technology largely depends on the innovation of image registration technology. The early image registration technology mainly uses point matching method, which is slow, low precision, and often requires manual selection of initial matching points, which cannot adapt to the fusion of ...
