Automating Lens Distortion Correction using Python & Discorpy
Manual lens correction is fine for one photo, but what if you need to correct hundreds in a custom fashion?
In this video, we break down the workflow for automating geometric distortion correction when standard GUI tools fall short.
Using a Nikon n1 image set as our test case, we explore why tools like RawTherapee and Hugin failed to provide a scalable solution. But the answer lies in discorpy, a Python library designed specifically for camera calibration.
Key Takeaways:
1. Scalability matters so we moved from manual GUIs to scriptable Python.
2. Input Data is King. How creating a composite graph-paper grid drastically improved our mathematical model.
3. Visualizing the Algorithm. We look at how the software identifies grid intersections to calculate warping.
4. Progress is achieving a reliable, repeatable workflow for scientific imagery.
If you are dealing with computer vision, photogrammetry, or just want to understand the math behind the image, this deep dive is for you.
