contour_to_world_plane_xld — CALIB plane op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.contour_to_world_plane_xld(contour, homography) (to call the implementation directly, import calib; calib.contour_to_world_plane_xld(contour, homography); from the registry, opscalib.get("contour_to_world_plane_xld"))

• HALCON equivalent: contour_to_world_plane_xld (the HALCON reference is a useful guide to its meaning and parameters)

• GPU: none (CPU reference implementation only)

Usage

Maps an XLD contour (dict {cs:[Nx2]}) to the world plane (contour_to_world_plane_xld).

Detailed usage guide

• camera_calibration family guide

• 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.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
