caltab_points — CALIB target op

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

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

• GPU: none (CPU reference implementation only)

Usage

Returns the ideal mark coordinates of a calibration plate (world, mm; origin = first mark) as (y, x) (caltab_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.

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