create_caltab — CALIB target op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.create_caltab(rows=7, cols=7, spacing=1.0) (to call the implementation directly, import caltab; caltab.create_caltab(rows=7, cols=7, spacing=1.0); from the registry, opscalib.get("create_caltab"))

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

• GPU: none (CPU reference implementation only)

Usage

Creates a calibration-plate description (ideal points, origin at the plate centre) (create_caltab).

Detailed usage guide

• camera_calibration family guide

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.

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

Runnable examples (verified samples that actually call this op)

• poc_caltab_chain_truth — py -3.11 examples/poc_caltab_chain_truth.py
