fit_line3 — 3D geometry op

• データ種: points → primitive
• 呼び出し: import fullseye as fs; fs.ledger.fit_line3(points) -> 'dict' (実装を直接呼ぶなら import measure3d; measure3d.fit_line3(points) -> 'dict'、台帳から引くなら ops3d.get("fit_line3"))

使い方

Total-least-squares 3-D line fit to (depth, row, col) points — the

largest principal axis through the centroid (orthogonal regression, isotropic in all three axes). Returns the centroid center (with cd/cr/cc), a unit direction (depth, row, col), and the RMS orthogonal residual. Raises ValueError on < 2 points or a coincident cluster with no defined direction.
