open3d.pipelines.registration.correspondences_from_features(source_features, target_features, mutual_filter=False, mutual_consistency_ratio=0.10000000149011612)#

Function to find nearest neighbor correspondences from features

Parameters:

  • source_features (open3d.pipelines.registration.Feature) – The source features stored in (dim, N).

  • target_features (open3d.pipelines.registration.Feature) – The target features stored in (dim, M).

  • mutual_filter (bool, optional, default=False) – filter correspondences and return the collection of (i, j) s.t. source_features[i] and target_features[j] are mutually the nearest neighbor.

  • mutual_consistency_ratio (float, optional, default=0.10000000149011612) – Threshold to decide whether the number of filtered correspondences is sufficient. Only used when mutual_filter is enabled.

Returns:
