env_params — DRIVE env op

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

• Call: import fullseye as fs; fs.ledger.env_params(when=None, lat: 'float' = 35.6581, lon: 'float' = 139.7414, *, sun=None, cloud: 'float' = 0.0, fog_mor: 'Optional[float]' = None, rain: 'float' = 0.0, headlamps: 'str' = 'off', north_yaw: 'float' = 90.0, lamp_luminance: 'float' = 10000.0, exposure: 'Optional[float]' = None, max_gain: 'float' = 1.0, glare_model: 'str' = 'stiles_holladay', fog_layer: 'float' = 100.0, seed: 'int' = 0) -> 'Dict[str, object]' (to call the implementation directly, import driveenv; driveenv.env_params(when=None, lat: 'float' = 35.6581, lon: 'float' = 139.7414, *, sun=None, cloud: 'float' = 0.0, fog_mor: 'Optional[float]' = None, rain: 'float' = 0.0, headlamps: 'str' = 'off', north_yaw: 'float' = 90.0, lamp_luminance: 'float' = 10000.0, exposure: 'Optional[float]' = None, max_gain: 'float' = 1.0, glare_model: 'str' = 'stiles_holladay', fog_layer: 'float' = 100.0, seed: 'int' = 0) -> 'Dict[str, object]'; from the registry, opsdrive.get("env_params"))

Usage

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

描画の条件をまとめる(:func:env_render に渡す)。

`when + 緯度経度(既定 = 東京の暦計算室の代表点)から太陽を出す。sun=(elevation, azimuth)` で直接与えてもよい。

`fog_mor = 気象光学距離 [m] (None で霧なし)、rain` ∈ [0, 1] (0 = 乾き。濡れた路面・雨筋の強さ)、

`headlamps ∈ {"off", "low", "high"}、exposure` = 固定の露出(輝度 → 画素値の倍率。None で自動)、

`max_gain` = 自動露出の倍率の上限(暗い夜に雑に明るくしない)。

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
