project_points — 3D render op

• Data kinds: points → keypoints

• Call: import match3d; match3d.project_points(points, K, R=None, t=None) (or ops3d.get("project_points"))

Usage

3-D point set (N,3) → image coordinates (u,v) and depth. Pinhole (the forward direction of depth_to_points).

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)

• pnp_pose_outliers — py -3.11 examples_3d/pnp_pose_outliers.py

• pose_estimation — py -3.11 examples_3d/pose_estimation.py
