peg_tip_from_rgbd — DRIVE pegsim op

• Data kinds: rgb × image2d × matrix → table

• Call: import fullseye as fs; fs.ledger.peg_tip_from_rgbd(rgb, depth, K, r_peg: 'float' = 0.005, peg_mask=None) -> 'dict' (to call the implementation directly, import pegsim; pegsim.peg_tip_from_rgbd(rgb, depth, K, r_peg: 'float' = 0.005, peg_mask=None) -> 'dict'; from the registry, opsdrive.get("peg_tip_from_rgbd"))

Usage

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

手首 RGB-D 1 枚からペグ先端の中心を 3-D(カメラ座標)で: ペグの画素 → depth の点群 → PCA の軸 → 既知半径の円柱当てはめ、

先端の軸方向は影の端(副画素、被覆率)を、投影した縁の円の端と一致させる模型で決める。

返り: `tip_cam(3,)、axis(先端 → 上、単位)、rms_cyl、n_pts、uv(先端の投影)、delta_axial`。

正直に: 試作の 16 姿勢で軸方向の誤差 max 0.83 px(横方向 0.004 px)—— 影の端 1 画素の被覆率だけから軸方向を読む限界で、

目標 0.3 px は未達。Raises `RuntimeError`: ペグが見えない(芯の画素 < 50)。
