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"))
Peg tip center in 3-D (camera coordinates) from 1 wrist RGB-D frame: peg pixels → depth point cloud → PCA axis → known-radius cylinder fit; the tip's position along the axis is set by a model that matches the end of the shadow (subpixel, coverage) to the end of the projected edge circle.

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)。
