overtake_return_gap — DRIVE pass 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.overtake_return_gap(*, lane_offset: 'float', lead_width: 'float', eye_xy=(0.0, -0.35), mirror_center_xy=(0.55, 0.0), mirror_normal_xy=None, mirror_width: 'float' = 0.25, eye_to_rear: 'float' = 2.8) -> 'Dict[str, object]' (to call the implementation directly, import drivepass; drivepass.overtake_return_gap(*, lane_offset: 'float', lead_width: 'float', eye_xy=(0.0, -0.35), mirror_center_xy=(0.55, 0.0), mirror_normal_xy=None, mirror_width: 'float' = 0.25, eye_to_rear: 'float' = 2.8) -> 'Dict[str, object]'; from the registry, opsdrive.get("overtake_return_gap"))

Usage

Gap (between the rear of the ego vehicle and the front of the overtaken vehicle) at which the overtaken vehicle appears entirely in the rearview mirror. Scenarios S086, S145.

教則 5-6-3(6)「追い越した車がルームミラーで見えるくらいの距離までそのまま進み」・7-2-3「追い越した車全体がルームミラーに映ってから」を幾何にする。座標は自車(x = 前、y = 左、原点 = 眼の真横の車の中心線)。前車は左の車線(横の中心 = lane_offset、幅 lead_width)で自車の後ろ。ルームミラーは平面鏡(中心 mirror_center_xy、幅 mirror_width、法線は眼の側)。法線を省くと、眼から鏡の中心への光線を真後ろ(−x)へ返す向き(drivedecide.mirror_aim_normal)。

映る ⇔ 仮想の眼 E'(眼を鏡の直線で折り返した点)と点を結ぶ線分が鏡の線分を通る。道に平行な直線の上では境目は 1 次方程式の根で、前の辺の両端(2 隅)で決まる。返り値: gap = 眼の後ろ eye_to_rear の自車の後端から、前の 2 隅が映る前車の前端までの距離、corner_limit_x(各隅が映る x の上限)、straight_back_s(真後ろの方向が鏡のどこを通るか。鏡の外なら真後ろが映らない = ValueError)。
