pyALDIC is an open-source Augmented-Lagrangian Digital Image Correlation package for high-accuracy, full-field displacement and strain measurement. It couples local IC-GN subset solves with a global FEM regularizer via ADMM, producing smoother, more robust fields under large deformation, discontinuities, and noisy images — while keeping sub-pixel precision.
Key Features:
- Augmented-Lagrangian (ADMM) global–local optimization with adaptive mesh refinement
- Built-in cross-platform desktop GUI (PySide6), localized in 8 languages
- Packaged on PyPI (
pip install al-dic) with versioned releases and a citable DOI - Sub-pixel accuracy under large deformation, discontinuities, and image noise
