model op• Data kinds: metrologymodel → scalar
• Call: import fullseye as fs; fs.ledger.add_metrology_object_ellipse_measure(model, row, col, phi, ra, rb, n: 'int' = 40) -> 'int' (to call the implementation directly, import metrology; metrology.add_metrology_object_ellipse_measure(model, row, col, phi, ra, rb, n: 'int' = 40) -> 'int'; from the registry, opsmeasure1d.get("add_metrology_object_ellipse_measure"))
> This operator's description has not been translated yet. The original text follows as it is.
楕円計測オブジェクトを追加(add_metrology_object_ellipse_measure)。
`phi = ra` 軸の向き(col 軸から、ラジアン)。
参照楕円(中心 `(row, col) [px]、phi 方向の半径 ra`、直交方向の半径
`rb)を model["objects"]` に積む(dict をその場で更新)。
`apply_metrology_model はパラメータ角 t を n` 等分した点を置き
(弧長等分ではないので、扁平な楕円では長軸端が密になる)、各点で楕円の
外向き法線 `∇F` に沿ってエッジを測り、楕円フィットで出し直す。
• `phi`: col 軸(x)から row 軸(画像下向き)へ測ったラジアン
(矩形の `phi` と同じ規約)。
• `ra, rb`: 半径 [px]。0 を入れると法線計算で 0 除算になるので避ける
(ここでは検証しない)。
• `n`: サンプル数(既定 40)。
• 返り値: 追加位置の index(0 始まり)。
• `apply 結果の params は row / col / phi / ra / rb で **ra >= rb`
(長軸が `ra)** に正規化され、rms` は代数残差ではなく中心からの
半径方向の幾何残差 [px]。
