moment_axes — 3D match_pose op

• Data kinds: points → axes

• Call: import match3d; match3d.moment_axes(points, weights=None) (or ops3d.get("moment_axes"))

Usage

The centroid and principal axes (the eigenvectors of the inertia tensor) of a point set or weighted points. The basis of pose estimation.

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)

• itokawa_pose_canonical — py -3.11 examples_3d/itokawa_pose_canonical.py

Ops the type connects to (they accept axes as input)
