plane_segmentation — 3D segment op

• Data kinds: points → labels

• Call: import segment3d; segment3d.plane_segmentation(points, thresh: 'float', min_inliers: 'int', max_planes: 'int' = 5, iters: 'int' = 300, seed: 'int' = 0) -> 'np.ndarray' (or ops3d.get("plane_segmentation"))

Usage

Extract up to max_planes planes one after another by iterated RANSAC (leftover points get −1).

• 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)

• object_segmentation — py -3.11 examples_3d/object_segmentation.py
