long op• Data kinds: table → table
• Call: import fullseye as fs; fs.ledger.road_profile(profile_xz, l0: 'float' = 0.0) -> 'Dict[str, np.ndarray]' (to call the implementation directly, import drivelong; drivelong.road_profile(profile_xz, l0: 'float' = 0.0) -> 'Dict[str, np.ndarray]'; from the registry, opsdrive.get("road_profile"))
Turns a polyline of horizontal distance and height (x, z) (same form as profile of drivecourse.course_slope) into a longitudinal profile over arc length l along the road surface.
Returns = {"l" (n,), "x" (n,), "z" (n,), "sin" (n−1,), "cos" (n−1,)}. l is the arc length of the break points starting from l0. The grade angle θ_i of segment i has sin = Δz/Δl, cos = Δx/Δl (flat outside both ends: θ = 0, z is the end value).
Raises ValueError: fewer than 2 points, non-finite, x not strictly increasing, grade of 45° or more.
