stick_radius_modelfree — DRIVE tacslip op

• Data kinds: matrix × matrix → table

• Call: import fullseye as fs; fs.ledger.stick_radius_modelfree(pts_c, u_px, rel: 'float' = 0.08, abs_px: 'float' = 0.05) -> 'dict' (to call the implementation directly, import tacslip; tacslip.stick_radius_modelfree(pts_c, u_px, rel: 'float' = 0.08, abs_px: 'float' = 0.05) -> 'dict'; from the registry, opsdrive.get("stick_radius_modelfree"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

模型なしの固着半径: 中心からの距離順に、内側 6 点の中央値 δ̂ から |ux − δ̂| が rel·|δ̂| + abs_px を超える最初の点と、その手前の点の中点の

半径 `c_px(分解能 = マーカー間隔)。core_px` = δ̂。pts_c は中心相対 (M, 2) [px]、u_px は (M, 2) [px]。Raises ValueError: 点が 6 個未満。
