v1.2.0

What's New

Fisheye Camera Model

• Added equidistant fisheye projection model for wide-angle monitoring cameras (FOV up to ~120°)
• Set "model": "fisheye" in camera params dict to use fisheye projection
• Supports radial distortion coefficients (k1-k4) and tangential distortion (p1, p2)
• Backward compatible: omitting "model" key defaults to pinhole

Optimizer Improvements

• Added weighted loss functions (mean_reprojection_error, huber_loss_weighted)
• Added center offset parameters (cx, cy) for optical center estimation
• Full support for fisheye model optimization in both CMA-ES and least squares

Documentation

• Added camera model comparison page with visual examples
• Moved MiniMa methods to cross-modal section in matching gallery
• Switched default installation instructions to PyPI (pip install alproj)
• Updated Japanese translations for all changes

Other

• Added scripts/compare_camera_models.py for benchmarking camera models
• Added comprehensive test suite for fisheye model (40+ tests)

Installation

pip install alproj==1.2.0
