Using command line arguments, you can easily change the filename + path of the output image. The last file, output.png, is the name of the resulting stitched image. image_stitching.py : This script includes my hack to extract an ROI of the stitched image for an aesthetically pleasing result.image_stitching_simple.py : Our simple version of image stitching can be completed in less than 50 lines of Python code!.Today we’ll be reviewing two Python scripts: I opted to make a subfolder for my scottsdale/ set of images in case I wanted to add additional subfolders here later. The input images go in the images/ folder.

Let’s see how this project is organized with the tree command: $ tree -dirsfirst

Noisy images that are not actually part of the panoramaįurthermore, their image stitching method is capable of producing more aesthetically pleasing output panorama images through the use of gain compensation and image blending.Ī complete, detailed review of the algorithm is outside the scope of this post, so if you’re interested in learning more, please refer to the original publication.

Unlike previous image stitching algorithms which are sensitive to the ordering of input images, the Brown and Lowe method is more robust, making it insensitive to: The algorithm we’ll be using here today is similar to the method proposed by Brown and Lowe in their 2007 paper, Automatic Panoramic Image Stitching with Invariant Features. OpenCV’s image stitching algorithm Figure 1: The stitching module pipeline implemented in the Stitcher class ( source). We’ll review the results of this first script, note its limitations, and then implement a second Python script that can be used for more aesthetically pleasing image stitching results.įinally, we’ll review the results of our second script and again note any limitations or drawbacks. In the first part of today’s tutorial, we’ll briefly review OpenCV’s image stitching algorithm that is baked into the OpenCV library itself via cv2.createStitcher and cv2.Stitcher_create functions.įrom there we’ll review our project structure and implement a Python script that can be used for image stitching.

To learn how to stitch images with OpenCV and Python, just keep reading! In today’s tutorial, we’ll be revisiting image stitching with OpenCV, including how to stitch more than two images together into a panoramic image.

However, the biggest problem with my original implementations is that they were not capable of handling more than two input images.

Applying a warping transformation using the homography matrix obtained from Step #3.

Using the RANSAC algorithm to estimate a homography matrix using our matched feature vectors.

Matching the descriptors between the images.

Detecting keypoints (DoG, Harris, etc.) and extracting local invariant descriptors (SIFT, SURF, etc.) from two input images.

Just under two years ago I published two guides on image stitching and panorama construction:īoth of these tutorials covered the fundamentals of the typical image stitching algorithm, which, at a bare minimum, require four key steps: Using today’s code you’ll be able to stitch multiple images together, creating a panorama of stitched images. In this tutorial, you will learn how to perform image stitching using Python, OpenCV, and the cv2.createStitcher and cv2.Stitcher_create functions.
