Crate spatialrust_metrics 

Point cloud comparison metrics for SpatialRust.

Distance metrics quantify how close two clouds are — the standard way to score registration, reconstruction, or downsampling against a reference.

Structs

CloudDistances

A bundle of directed and symmetric cloud-to-cloud distance statistics.

Functions

chamfer_distance

Symmetric Chamfer distance between two clouds (sum of mean squared NN distances in both directions). Lower is better; zero for identical clouds.

cloud_distances

Computes directed NN distance statistics between a and b in both directions with a single KD-tree per side.

hausdorff_distance

Symmetric Hausdorff distance between two clouds (the largest NN distance in either direction). Captures the worst-case discrepancy.
