icp_point2point_3d — 3D refine op

• Data kinds: points × points → pose

• Call: import match3d; match3d.icp_point2point_3d(src, dst, iters=50, init_R=None, init_t=None, tol=1e-06, max_corr_dist=None, trim_ratio=None, device='cpu') (or ops3d.get("icp_point2point_3d"))

Usage

Refine point sets by point-to-point ICP (Kabsch/SVD).

References (sample data, literature)

• 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)

• gicp_register — py -3.11 examples_3d/gicp_register.py
