cr_synthetic — DRIVE commonroad op

• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.cr_synthetic(kind: 'str' = 'tjunction', *, dt: 'float' = 0.1, speed_limit: 'float' = 13.89, v0: 'float' = 8.0) -> 'str' (to call the implementation directly, import drivecommonroad; drivecommonroad.cr_synthetic(kind: 'str' = 'tjunction', *, dt: 'float' = 0.1, speed_limit: 'float' = 13.89, v0: 'float' = 8.0) -> 'str'; from the registry, opsdrive.get("cr_synthetic"))

Usage

Returns, as a string, a minimal CommonRoad 2020a XML for tests and CI.

tjunction: lanelet 100(直線 40 m, +x)→ 101(左 90° 円弧、中心線半径 12 m)→ 102(直線 40 m, +y)、対向 lanelet 200 (100 の左隣、−x 向き)に対向車 1 台(8 m/s、矩形 4.5 × 1.8)、標識 274(speed_limit m/s)は 3 本すべてに、stopLine は 100 の終端(交差点の手前)、planning problem = (5, 0) から v0 でゴール lanelet 102・time_step [100, 200]・速度 [0, 15]。straight: 101 も直線(3 本で 120 m)。blocked: straight の 101 の中央に静止障害物(衝突の門用)。車線幅 3.5 m。中心線の長さ = 40 + 6π(≒ 18.85、円弧は 16 分割の折線) + 40(tjunction)/ 120(straight)。

Raises ValueError: kind が SYNTHETIC_KINDS 以外、dt / speed_limit / v0 が正でない。
