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"))
Field of view of a convex mirror (spherical, radius radius, aperture diameter aperture) seen by an eye on the axis at eye_distance (from the vertex).
> The detailed description below is the original text — the summary and the headings are translated.
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。
