Hello,
I am trying to calibrate fisheye camera with a field of view (FOV) of 195°. I came across a previous post,which mentions that OpenCV might not be suitable for calibrating cameras with FOV > 180°. Since that post is three years old, I wanted to check if the situation has changed and whether the OpenCV fisheye module in version 4.5 (or later) can now handle such cases effectively. When I try this module, I notice significant reprojection errors, particularly for points located farther from the center of the image.
As an alternative, I tried calibrating my fisheye camera using MATLAB, which yielded lower reprojection errors. However, I am unsure how to properly integrate the calibration results from MATLAB into OpenCV for further operations.
Additionally, has anyone used puzzlepaint_camera_calibration for fisheye camera calibration? If so, how does it compare in terms of accuracy and usability?
Any insights would be greatly appreciated
