gicp — 3D gicp op

• Data kinds: points × points → pose

• Call: import gicp; gicp.gicp(source, target, max_iter: 'int' = 30, k: 'int' = 20, epsilon: 'float' = 0.001, tol: 'float' = 1e-08, init=None) -> 'dict' (or ops3d.get("gicp"))

Usage

Estimate the rigid transform (R,t) by Generalized-ICP (covariance-weighted Mahalanobis ICP).

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• gicp_register — py -3.11 examples_3d/gicp_register.py

Ops the type connects to (they accept pose as input)

fuse_to_voxel · pose_error · bundle_adjust · mean_reprojection_error · optimize_pose_graph · relative_pose · mean_edge_error · rotation_translation_error
