depth_to_points — 3D transform op

• Data kinds: depth → points

• Call: import match3d; match3d.depth_to_points(depth, fx, fy, cx, cy, stride=1) (or ops3d.get("depth_to_points"))

Usage

Depth map (2.5-D) → point cloud (pinhole back-projection). It connects the depth row to every method.

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)

• structured_light_scan — py -3.11 examples_3d/structured_light_scan.py

• transforms_repr — py -3.11 examples_3d/transforms_repr.py
