- Software

- Library
Python library for camera calibration: it fits OpenCV camera models and verifies the results, and falls back to spline-based distortion models when OpenCV's model is not enough.

What it does
- Extracts calibration frames from ChArUco boards and calibrates a camera model from them.
- Filters out bad board detections automatically before fitting.
- Estimates warp of non-flat calibration targets to improve the calibration.
- Offers B-spline distortion models for cheap or wide-angle lenses, with the same API as the OpenCV models.
- Includes analysis plots for residuals, distortion, detection coverage and model differences.
- Provides UnprojectLUT, a cached pixel-grid lookup table for fast runtime unprojection, with a standalone C++ runtime.
