RANSAC Panorama Stitching

Python Version 3.7

The Project

This project stitches images together to create a Panorama. Images are taken from different perspectives and transformed to fit together by using SIFT feature detection and RANSAC algorithm for homography transformations.

Set Up Instructions

1. Ensure that your Python version is 3.7 and pip is installed

   • Python 3.7
     https://www.python.org/downloads/release/python-370/
   • pip
     https://pip.pypa.io/en/stable/installing/

2. Open the project folder (Project_RANSAC) as a Python project in your choice of IDE (i.e. PyCharm)
   Set the working directory is set to /Project_RANSAC/src

3. Select Python 3.7 as your interpreter
   OpenCV Contrib v.3.4.2.16 files are found in the project folder.

   • Required Packages
     • numpy
       pip install numpy
     • OpenCV Contrib v.3.4.2.16
       • 64-bit: opencv_contrib_python-3.4.2.16-cp37-cp37m-win_amd64.whl
         pip install opencv_contrib_python-3.4.2.16-cp37-cp37m-win_amd64.whl
       • 32-bit: opencv_contrib_python-3.4.2.16-cp37-cp37m-win32.whl
         pip install opencv_contrib_python-3.4.2.16-cp37-cp37m-win32.whl

Running the Project

• Harris Corner Response threshold, RANSAC Iterations and RANSAC threshold can be specified in the global variables found in Main.py (Line 6-8)

1. Run Main.py to execute the program
2. To go to the next image, press any key (excluding Esc). Output images are saved in src/project_images/output
   The sequence of the images are as follows:
   1. Boxes Harris Corner Detection
      Rainier1 Harris Corner Detection
      Rainier2 Harris Corner Detection
   2. SIFT matches for Rainier 1-2
   3. RANSAC Matches for Rainier1 and Rainier2
   4. Stitched Rainier1 and Rainier2 (R1-2)
   5. RANSAC Matches for R1-2 and Rainier3 (R1-3)
   6. RANSAC Matches for R1-3 and Rainier4 (R1-4)
   7. RANSAC Matches for R1-4 and Rainier5 (R1-5)
   8. RANSAC Matches for R1-5 and Rainier6 (R1-6)
   9. Stitched Rainier1-6 (Scaled 50% For Displaying)
   10. RANSAC Matches for Japan1 and Japan2 (JP1-2)
   11. RANSAC Matches for JP1-2 and Japan3 (JP1-3)
   12. Stitched Japan1-3
   13. RANSAC Matches for Hanging1 and Hanging1-2
   14. Stitched Hanging1-2
