Handling Camera Distortion

[jonas0huber]

While working with the AXIS P3827-PVE, I recently encountered a challenge that might be familiar to other users: lens distortion.

In my setup, the camera is installed about 3 meters above the ground, mounted on a pole and angled downward at approximately 45 degrees. However, the 180 degree lens introduces some warping or distortion in the video footage because of the lens geometry.

Naturally, I began to wonder:
Are there tools, APIs, or recommended post-processing workflows that Axis provides to help correct for this kind of distortion?

More specifically, I’m looking for any Python-based solutions—whether libraries, scripts, or even wrappers for the VAPIX API or other Axis SDKs—that can help automate image correction as part of a video processing pipeline.

Thanks for your help in advance :)

This automatically generated reply acts as a friendly reminder.

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

@jonas0huber did you tried this ?

Thanks for that!
Unfortunately, I only have access to the MP4 file, so I can't use the app-based method you mentioned. Also, I'm specifically looking for a solution that can be automated using a script, ideally in Python or something that can be integrated into a processing pipeline.

If you know of any tools or libraries that work directly with video files, I’d love to hear about them!

@jonas0huber may this works https://github.com/letmaik/lensfunpy

Also here is some stuff https://discorpy.readthedocs.io/en/latest/tutorials/methods.html

Hi @jonas0huber ,
I know you are looking for some tool in Python 😉

Have a look at this if it can be built and used externally with MP4:
Camera calibration for lens distortion
