Resource Overview

Image stitching is a technique that synthesizes a wide-angle scene image from a sequence of discretized images captured from the real world. When two images with overlapping correlations are available, image stitching aims to merge them into a single composite image. The panoramic stitching process typically involves spatial projection, matching and alignment, and overlay fusion procedures, which can be implemented using feature detection algorithms like SIFT or ORB for accurate registration.

Detailed Documentation

In this article, we explore image stitching technology, a method for synthesizing discrete image sequences captured from the real world into a wide-angle scene image. When dealing with two images with overlapping regions, image stitching combines them into a larger composite image. The panoramic stitching process generally involves three key stages: spatial projection, matching and alignment, and overlay fusion. These steps aim to seamlessly integrate multiple images to produce a more comprehensive perspective and detailed scene representation. Implementation typically employs block matching algorithms where corresponding regions are identified using similarity metrics (e.g., normalized cross-correlation), followed by homography matrix estimation for geometric alignment and multi-band blending techniques to minimize visible seams.
