class
open3d.registration.
CorrespondenceCheckerBasedOnEdgeLength
¶ Check if two point clouds build the polygons with similar edge lengths. That is, checks if the lengths of any two arbitrary edges (line formed by two vertices) individually drawn withinin source point cloud and within the target point cloud with correspondences are similar. The only parameter similarity_threshold is a number between 0 (loose) and 1 (strict)
-
Check
(self, source, target, corres, transformation)¶ Function to check if two points can be aligned. The two input point clouds must have exact the same number of points.
- Parameters
source (open3d.geometry.PointCloud) – Source point cloud.
target (open3d.geometry.PointCloud) – Target point cloud.
corres (open3d.utility.Vector2iVector) – Correspondence set between source and target point cloud.
transformation (numpy.ndarray[float64[4, 4]]) – The estimated transformation (inplace).
- Returns
bool
-
__init__
(*args, **kwargs)¶ Overloaded function.
__init__(self: open3d.registration.CorrespondenceCheckerBasedOnEdgeLength, arg0: open3d.registration.CorrespondenceCheckerBasedOnEdgeLength) -> None
Copy constructor
__init__(self: open3d.registration.CorrespondenceCheckerBasedOnEdgeLength, similarity_threshold: float = 0.9) -> None
-
property
similarity_threshold
¶ For the check to be true,
\(||\text{edge}_{\text{source}}|| > \text{similarity_threshold} \times ||\text{edge}_{\text{target}}||\) and
\(||\text{edge}_{\text{target}}|| > \text{similarity_threshold} \times ||\text{edge}_{\text{source}}||\)
must hold true for all edges.
- Type
float value between 0 (loose) and 1 (strict)
