pc_thinning_report — 3D `resolution` op

• 資料種類:points × points → table

• 呼叫: import fullseye as fs; fs.ledger.pc_thinning_report(points, thinned, k=8, radius=None)(要直接呼叫實作,import meshres; meshres.pc_thinning_report(points, thinned, k=8, radius=None);從台帳取用則 ops3d.get("pc_thinning_report"))

用法

點雲抽稀移除了什麼,以及是否動到了稀有點(`table`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

`removed count and fraction; removed_spacing` percentiles of the

local spacing (:func:pc_density) of the removed points versus

`kept_spacing; isolated_removed` counts removed points whose

nearest-neighbour distance exceeded *radius* (default: the 95th percentile

of nearest-neighbour distances) — a thinning that removed such points has

discarded exactly the rare, isolated observations a survey exists to find

(:func:pc_poisson_disk with the same radius removes none of them, by

construction); `max_gap` is the largest distance from any removed point

to the kept cloud (the biggest hole the thinning made).
