• 呼叫: import fullseye as fs; fs.ledger.fit_box3(points) -> 'dict'(要直接呼叫實作,import measure3d; measure3d.fit_box3(points) -> 'dict';從台帳取用則 ops3d.get("fit_box3"))
用 PCA 擬合有向長方體(快速、抗噪;與 pcseg.obb 同一構造)。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
Unlike pcseg.obb it returns the measure-style dict. Axes are the principal directions of the point spread; extents come from the projected span. Returns center (cd/cr/cc), axes (3, 3 — unit ROW vectors, depth/row/col components), sorted half-extents l1 >= l2 >= l3, full size, volume, corners (8, 3), and the RMS point-to-box-surface distance. For the true minimum-volume box use smallest_box3. Raises ValueError on < 4 points or a degenerate (flat) set.
