ball_truth — DRIVE `ballworld` op

• Data kinds: table × table → table

• Call: import fullseye as fs; fs.ledger.ball_truth(world: 'dict', i: 'int', cam: 'dict') -> 'dict' (to call the implementation directly, import ballworld; ballworld.ball_truth(world: 'dict', i: 'int', cam: 'dict') -> 'dict'; from the registry, opsdrive.get("ball_truth"))

Usage

Ground-truth projection of ball i: (col, row) of the center, image radius [px] (≈ f·r/depth), (col, row) of the marker center (NaN if on the back side).
