• Call: import fullseye as fs; fs.ledger.mirror_blind_zone(eye_xy, mirror_center_xy, mirror_normal_xy, mirror_width, *, mirror_radius=inf, direct_limit_deg: 'float' = 100.0, roi=(-15.0, -2.0, 0.9, 4.4)) -> 'Dict[str, object]' (to call the implementation directly, import drivedecide; drivedecide.mirror_blind_zone(eye_xy, mirror_center_xy, mirror_normal_xy, mirror_width, *, mirror_radius=inf, direct_limit_deg: 'float' = 100.0, roi=(-15.0, -2.0, 0.9, 4.4)) -> 'Dict[str, object]'; from the registry, opsdrive.get("mirror_blind_zone"))
The region to the left rear of the ego vehicle that is covered neither by the left door mirror nor by direct view (2D, top view).

座標は車の x = 前・y = 左。eye_xy = 運転者の眼、mirror_center_xy = 鏡の中心、mirror_normal_xy = 鏡の法線(眼の側を向く。mirror_aim_normal で作れる)、mirror_width = 鏡の幅(上から見た弦の長さ)、mirror_radius = 凸面の曲率半径(inf = 平面鏡)。direct_limit_deg = 首を回さずに直接見える方位の上限(前方から左回り。100° は 仮定)。roi = (x_min, x_max, y_min, y_max) の対象領域(左の隣の車線。鏡の本体と車体を含まないように置くこと = 鏡の光線が車体を通るかは見ていない)。
鏡で見える領域 = 鏡の両端で反射した 2 本の光線に挟まれ、かつ鏡の弦より眼の側。直接見える = 眼から見た方位 ≤ 上限。死角 = roi ∖ (鏡 ∪ 直接) を 互いに素な凸多角形の列 で返す(凸 ∖ 凸 = 半平面を 1 つずつ外した和)。
返り値: pieces(凸多角形 (k, 2) の list)、area、mirror_edges(両端の点 (2, 2))、mirror_rays(両端の反射光線の単位ベクトル (2, 2))、mirror_area / direct_area(roi の中で見える面積)。
