circle_fit_known_radius — DRIVE pegsim op

• Data kinds: matrix → table

• Call: import fullseye as fs; fs.ledger.circle_fit_known_radius(points, r: 'float', iters: 'int' = 30) -> 'dict' (to call the implementation directly, import pegsim; pegsim.circle_fit_known_radius(points, r: 'float', iters: 'int' = 30) -> 'dict'; from the registry, opsdrive.get("circle_fit_known_radius"))

Usage

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

半径 r が既知の円を 2-D 点列 (row, col) に当てる(中心だけを Gauss-Newton で解く。部分弧でも安定)。

:func:measure.fit_circle(代数的、半径も未知)と同じ入出力の規約(`cy・cx・rms`)。ペグの断面のように半径が

図面で分かっている対象は、半径を固定したほうが短い弧でも中心が決まる(自由な当てはめは弧が短いと半径と中心が相殺する)。

Raises `ValueError`: 点が 2 つ未満、非有限、r ≤ 0。
