Get Highest-Layer Points

Function

This Step is used to get the points in highest layer along the specified direction.

Usage Scenario

A general point cloud filtering Step. No fixed usage scenarios.

Input and Output

  • Input

  1. Highest layer points of point cloud input to this port will be extracted.

  2. Pose used to define the vertical direction (optional, if this port is not used, the parameter “Reference Direction” will be used; if inputting multiple poses, only the first will be used.).

  • Output

  1. Highest layer points extracted.

Parameters Description

Reference Direction

Instruction: This parameter is used to select the reference direction, X, Y and Z included.
Default Value: x=0; y=0; z=1.0。
Suggested Value: Please set according to the actual situation.

Layer Settings

Only Get Highest One
Instruction: This parameter decides whether to only get the highest point along the specified direction or not.
Default value: Unselected
Suggested Value: Please set according to the actual situation.
Layer Height
Instruction: This parameter is used to set the height of every layer (in m).
Default Value: 0.1
Suggested Value: Please set according to the actual situation.
Layer Tolerance
Instruction: This parameter is used to set the upper limit of the height tolerance (in m) between the highest layer and other layers. Tolerance equals the multiplication of “Layer Height” and “Layer Tolerance”. If the height differene is less than the parameter, they belong to the same layer(the highest layer).
Default Value: 1.0
Suggested Value: Please set according to the actual situation.
