Get Highest Layer Clouds

Function

This Step sorts the centers of point cloud parts in descending order along a specified direction, and then obtains the highest-layer point cloud.

Sample Scenario

Keep point clouds that meet the requirements along the user-specified reference direction. Unlike Get Highest Layer Points, this Step process the point cloud directly and usually follows Steps including Point Cloud Clustering 、 Apply Masks to Point Cloud, etc.

Input and Output

Parameters

Reference Direction

Default Value: x=0; y=0; z=1.0

Instruction: This parameter is used to select the reference direction, including X, Y and Z.

Layer Settings

Only Get Highest One

Default Value: False

List of Values: True, False

Instruction: This parameter decides whether to only get the highest result along the specified direction or not.

Layer Height

Default Value: 0.1 m

Instruction: This parameter is used to set the height of every layer (in m).

Layer Tolerance

Default Value: 1.0

Instruction: This parameter is used to set the upper limit of the height tolerance (in m) between the highest layer and other layers. If the distance from one item to the highest item is smaller than the multiplication of Layer Height and Layer Tolerance , this item belongs to the highest layer.

Cloud Settings

Use Max Size Cloud Normal

Default Value: False

List of Values: True, False

Instruction: This parameter decides whether to use the normal of the point cloud with the greatest size as the reference direction or not. If checked True, Reference Direction will be invalid.

Max Size Cloud Normal Z Dir

Default Value: Negative

List of Values: Positive, Negative

Instruction: Specify the normal direction of the max size point cloud as positive or negative in the current coordinate. This parameter is only valid when Use Max Size Cloud Normal is checked as True.
