fit_plane3 — 3D geometry op

• 数据种类:points → primitive

• 调用: import fullseye as fs; fs.ledger.fit_plane3(points) -> 'dict'(要直接调用实现,import measure3d; measure3d.fit_plane3(points) -> 'dict';从台账取用则 ops3d.get("fit_plane3"))

用法

对 `(depth, row, col)` 点做最小二乘 3-D 平面拟合。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

through the centroid whose normal is the smallest principal axis (minimises the

sum of squared point-to-plane distances). Returns `center (cd/cr/cc`), a

unit `normal` (depth, row, col), and the RMS point-to-plane residual. Raises

`ValueError` on < 3 points or a collinear set (the normal is undefined).
