spiral_search_points — DRIVE `pegsym` op

• Data kinds: scalar × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.spiral_search_points(pitch: 'float', step: 'float', r_max: 'float', centre=(0.0, 0.0)) -> 'dict' (to call the implementation directly, import pegsym; pegsym.spiral_search_points(pitch: 'float', step: 'float', r_max: 'float', centre=(0.0, 0.0)) -> 'dict'; from the registry, opsdrive.get("spiral_search_points"))

Usage

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

横ずれの探索点: Archimedes のらせん r = p φ/(2π) を弧長 `step [m] ごとに(中心から)、半径 r_max` まで。隣の巻きとの間隔 =

`pitch`。面取りが捕まえる半径を c とすると、p ≤ 2c かつ step ≤ 2c で抜けなく覆う(隣の巻きの間の点の最悪の距離 √((p/2)² + (s/2)²)

≤ c が十分条件、`worst_gap で返す)。返り points(N, 2)、worst_gap、n`。

Raises ValueError: pitch・step・r_max ≤ 0、点が 200,000 を超える。
