Tuning knobs for estimate_local_steps.

Fields

k_neighbors: usize

Nearest-neighbor count fed to the KD-tree per point. Defaults to 8 — enough for a 4-connected grid even when a handful of neighbors are missing.

max_step_factor: F

Clamp neighbors whose |offset| exceeds this factor times the local median distance. Defaults to 3.0.

sector_half_width_rad: F

Half-width (radians) of the u and v sectors. Defaults to π/6 (30°) so that grid diagonals — which sit exactly at 45° on an orthogonal chessboard — are excluded from both sectors rather than polluting one of them. Widen this if the detector emits heavily-warped grids whose on-axis neighbors rotate more than 30° away from the lattice axes.

bandwidth_rel: F

Bandwidth for the 1-D mean-shift mode finder, expressed as a fraction of each sector’s median |offset|. Defaults to 0.15.

mean_shift_max_iters: u32

Maximum mean-shift iterations before falling back to the sector median. Defaults to 20.

mean_shift_convergence_rel: F

Mean-shift converges when the update magnitude drops below bandwidth × convergence_rel. Defaults to 1e-3.

confidence_denominator: F

Denominator used when converting supporter count to confidence. A well-connected interior corner has up to 4 supporters in each axis (2 left/right, 2 up/down), so the default of 4.0 keeps well-supported corners at confidence ≥ 1.0.
