Extract 3D Points in Cylinder¶
Function¶
Extract point clouds inside specified cylinders, the point clouds outside the cylinders will be discarded.
Usage Scenario¶
A general point cloud extraction Step. No fixed usage scenarios.
Input and Output¶
Parameters¶
- Shape Type
- Default Value: RingList of Values: Cylinder, Ring, SectorInstruction: 3D points inside this specified shape will be extracted.
Z Direction Properties
- Min Z Value
- Default Value: -0.1 mInstruction: This parameter is used to set the lower limit of distance threshold (in m) along Z axis of the reference coordinate.
- Max Z Value
- Default Value: 0.1 mInstruction: This parameter is used to set the upper limit of distance threshold (in m) along Z axis of the reference coordinate.
Ring and Sector Radius Properties
- Inner Radius
- Default Value: 0.05 mInstruction: The minimum distance on XY-plane. To obtain a solid cylinder, this parameter needs to be set as
0
. - Outer Radius
- Default Value: 0.1 mInstruction: The maximum distance on XY-plane.
Sector Angle Properties
The following two parameters appear after choosing Sector
in Shape Type, and they are used to configure the shape of the sector.
- Start Angle
- Default Value: 180°Instruction: The start angle of the sector on XY-plane.
- End Angle
- Default Value: 180°Instruction: The end angle of the sector on XY-plane.
Usage Settings for Input Clouds
- Check If Object Inside Cylinder by Its Point Center
- Default value: UnselectedInstruction: If this option is selected, the center of the object point cloud is used to check if it is inside the cylinder.
- Input Point Cloud Usage
- Default Value: AllList of Values: All, FirstOnlyInstruction: This parameter decides whether to only use the first input point cloud.
