annotate3d_label — 3D annotate3d op

• Data kinds: image2d × text → image2d

• Call: import annotate3d; annotate3d.annotate3d_label(img, text, anchor, pose, K, depth=None, offset=(26.0, -22.0), color='emphasis', width=1.5, cap_size=3.0, font_size=12, pad=4, box_alpha=0.72, text_color=None, occlusion_tol=0.01, scheme='okabe_ito', font_path=None) (or ops3d.get("annotate3d_label"))

Usage

Returns an image (image2d): text with a leader line attached to a 3-D anchor.

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)

• annotate3d_figure — py -3.11 examples_3d/annotate3d_figure.py

Ops the type connects to (they accept image2d as input)
