segment_rigid_motions — 3D motion_segment op

• Data kinds: points × points → labels

• Call: import motion_seg3d; motion_seg3d.segment_rigid_motions(pts0, pts1, thresh, max_bodies: 'int' = 5, min_inliers=None, n_iter: 'int' = 100, k_sample: 'int' = 6, seed: 'int' = 0) -> 'dict' (or ops3d.get("segment_rigid_motions"))

Usage

Split two point sets into the rigid bodies whose motion agrees (multi-body segmentation by iterated RANSAC).

• 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)

• motion_seg — py -3.11 examples_3d/motion_seg.py
