pc_thinning_report — 3D `resolution` op

• 数据种类:points × points → table

• 调用: import fullseye as fs; fs.ledger.pc_thinning_report(points, thinned, k=8, radius=None)(要直接调用实现,import meshres; meshres.pc_thinning_report(points, thinned, k=8, radius=None);从台账取用则 ops3d.get("pc_thinning_report"))

用法

点云抽稀移除了什么,以及是否动到了稀有点(table)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

removed count and fraction; removed_spacing percentiles of the local spacing (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 (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).
