ball_track — DRIVE balltrack op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.ball_track(detections, *, max_jump: 'float' = 40.0, min_score: 'float' = 0.0) -> 'dict' (to call the implementation directly, import balltrack; balltrack.ball_track(detections, *, max_jump: 'float' = 40.0, min_score: 'float' = 0.0) -> 'dict'; from the registry, opsdrive.get("ball_track"))

Usage

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

コマごとの候補列 `detections[k] = ball_detect(frame_k) を 1 本の軌跡に繋ぐ(等速予測に最も近い候補、max_jump` px 以内)。

返り値 `{"frame" (N,), "col" (N,), "row" (N,), "radius" (N,), "found" (K,) bool}`(見つからないコマは飛ばす)。
