Data container for Digital Image Correlation (DIC) analysis results.

This dataclass stores the displacements, convergence info, and correlation data associated with a DIC computation.

Variables:

  • ss_x (np.ndarray) – The x-coordinates of the subset centers (in pixels).

  • ss_y (np.ndarray) – The y-coordinates of the subset centers (in pixels).

  • u (np.ndarray) – Horizontal displacements at each subset location.

  • v (np.ndarray) – Vertical displacements at each subset location.

  • mag (np.ndarray) – Displacement magnitude at each subset location, typically computed as sqrt(u^2 + v^2).

  • converged (np.ndarray) – boolean value for whether the subset has converged or not.

  • cost (np.ndarray) – Final cost or residual value from the correlation optimization (e.g., ZNSSD).

  • ftol (np.ndarray) – Final ftol value from the optimization routine, indicating function tolerance.

  • xtol (np.ndarray) – Final xtol value from the optimization routine, indicating solution tolerance.

  • niter (np.ndarray) – Number of iterations taken to converge for each subset point.

  • shape_params (np.ndarray | None) – Optional shape parameters if output during DIC calculation (e.g., affine, rigid).

  • filenames (list[str]) – name of DIC result files that have been found
