Parameter Settings:

Name	Type	Valid Range	Default Value	Meaning
Axial Distance Threshold	Integer	[1, 5000]	50	Traversing the point cloud. If the distance between two points is greater than this threshold, it is considered that it is not the same cluster, that is, the greater the value, the greater the possibility of merging
Axial dimension ratio threshold	Integer	[0, 1]	0.1	If 0, do not use dimension to judge whether to merge, only use distance to judge. Traversing the point cloud, if the ratio of the minimum bounding box size of the two points in the axial direction is less than this threshold, it is considered that it is not the same cluster, that is, the smaller the value, the greater the possibility of merging
Merge Axis	List	None	[0, 0, 1]	Specify the clustering axis, clustering in this axis direction
Clustering minimum points	Integer	[1, 4000000]	100	Minimum number of Point Cloud Points per Cluster
Clustering max points	Integer	[1, 4000000]	4000000	Maximum number of Point Cloud Points per Cluster
Sort order	String	['from small to large', 'from large to small']	from small to large	Sort order
Enable node	Bool	None	True	Turn on node functionality

Axial Distance Threshold

Integer

[1, 5000]

Traversing the point cloud. If the distance between two points is greater than this threshold, it is considered that it is not the same cluster, that is, the greater the value, the greater the possibility of merging

Axial dimension ratio threshold

Integer

[0, 1]

0.1

If 0, do not use dimension to judge whether to merge, only use distance to judge. Traversing the point cloud, if the ratio of the minimum bounding box size of the two points in the axial direction is less than this threshold, it is considered that it is not the same cluster, that is, the smaller the value, the greater the possibility of merging

Merge Axis

List

None

[0, 0, 1]

Specify the clustering axis, clustering in this axis direction

Clustering minimum points

Integer

[1, 4000000]

100

Minimum number of Point Cloud Points per Cluster

Clustering max points

Integer

[1, 4000000]

4000000

Maximum number of Point Cloud Points per Cluster

Sort order

String

['from small to large', 'from large to small']

from small to large

Sort order

Enable node

Bool

None

True

Turn on node functionality

Retain all results

Bool

[True, False]

True

For each input point cloud, whether to output all segmentation results, if false, the number of results will be retained by
