convex_mirror_fov — DRIVE decide 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.convex_mirror_fov(radius, aperture, eye_distance) -> 'Dict[str, float]' (to call the implementation directly, import drivedecide; drivedecide.convex_mirror_fov(radius, aperture, eye_distance) -> 'Dict[str, float]'; from the registry, opsdrive.get("convex_mirror_fov"))

Usage

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

凸面鏡(球面、半径 `radius、開口の直径 aperture)を軸上 eye_distance`(頂点から)の眼で見たときの視野角。

厳密(軸を含む断面): h = a/2、α = asin(h/R)、s = R − sqrt(R² − h²)、β = atan(h/(D + s))、

全視野角 = 2(β + 2α)。`radius = inf` は平面鏡 2 atan(h/D)。

近軸: ≈ a (1/D + 2/R)(誤差は h³ の桁。h/R ≲ 0.2 かつ h/D ≲ 0.2 で相対誤差が数 % 以内が目安)。

返り値: `fov_rad / fov_deg(厳密)、fov_paraxial_rad、flat_fov_rad`(同じ開口の平面鏡)、

`widening(= fov / flat_fov、凸面で何倍広く見えるか)、edge_tilt_rad = α、eye_angle_rad` = β。

h ≥ R(半球より大きい開口)は ValueError。
