peg_offset_from_rgbd — DRIVE pegsim op

• Data kinds: rgb × image2d × matrix × matrix → table

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

Usage

Relative offset (dx, dy) [m] of the peg tip with respect to the hole center, in world (carriage) coordinates, from 1 wrist RGB-D frame — the observation for visual servoing.

> The detailed description below is the original text — the summary and the headings are translated.

R_cam_to_world はカメラ座標のベクトルを世界へ回す 3×3(hand-eye)。ずれは板の平面内の成分、height は先端の板からの高さ。hole_radius を与えると穴の円を既知半径で当てる(hole_centre_from_rgbd)。

返り: hole・tip(各計測の dict)、dx・dy・height。試作(16 姿勢): |dx|, |dy| の最大 0.010 mm。
