gen_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.gen_caltab(rows=7, cols=7, spacing=1.0, radius=0.3, image_size=256) (to call the implementation directly, import caltab; caltab.gen_caltab(rows=7, cols=7, spacing=1.0, radius=0.3, image_size=256); from the registry, opscalib.get("gen_caltab"))

• GPU: none (CPU reference implementation only)

Usage

Generates an image of a calibration plate with a grid of circular marks (gen_caltab).

返りは image(板の絵)・centers(絵の上のマーク中心 (row, col) [px])に加えて、create_caltab と同じ板の記述(points = 板中心を原点にした (y, x) [mm]、spacing) を持つ —— この dict はそのまま sim_caltab / find_marks_and_pose の板として使える。★2026-10-23 まで spacing は受け取るだけで返りのどこにも効いていなかった(台帳の探針が「効かないつまみ」として検出)。絵の配置は image_size で決まり、実寸は points に載る。

• 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.
