rmse_inliers — 3D registration_metrics op

• Data kinds: points × points → measurement

• Call: import fullseye as fs; fs.ledger.rmse_inliers(source, target, transform, thresh: 'float') (to call the implementation directly, import registration_eval; registration_eval.rmse_inliers(source, target, transform, thresh: 'float'); from the registry, ops3d.get("rmse_inliers"))

• Return value through the ledger: fullseye.ledger.rmse_inliers(...) returns only the declared out type measurement (the underlying function also returns auxiliary values). When you need what was dropped, use fullseye.ledger.rmse_inliers.raw(...) or call registration_eval.rmse_inliers directly.

• Underlying return: (rmse, n_inliers) → rmse

Usage

The RMSE over the inlier correspondences (residual < thresh) and the inlier count. → (rmse, n_inliers).

Assumes the index correspondence source[i]↔target[i] (same as inlier_ratio). If there are 0 inliers the RMSE is undefined → returns (nan, 0) (honest; nothing fabricated). Shape mismatch or non-(N,3) raises ValueError (fail-closed).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• reg_eval — py -3.11 examples_3d/reg_eval.py
