relative_motion — DRIVE `ttc` op

• Data kinds: matrix × matrix → matrix

• Call: import fullseye as fs; fs.ledger.relative_motion(pose0, pose1, motion=None) -> 'np.ndarray' (to call the implementation directly, import drivettc; drivettc.relative_motion(pose0, pose1, motion=None) -> 'np.ndarray'; from the registry, opsdrive.get("relative_motion"))

Usage

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

2 コマの間の、カメラ座標で見た点の剛体運動 `T_rel(P_c1 = T_rel · P_c0`)。

`pose0 / pose1 は各コマの world → camera(:func:driveworld.camera_pose)。motion` は対象が世界で動いた

4×4(world → world、静止した世界なら None = 単位)。`T_rel = pose1 · motion · pose0⁻¹`。
