Function

This Step uses the set thresholds to judge whether the input point clouds meet the requirements.

Usage Scenario

This Step is usually used to judge whether each input point cloud meets the requirements based on a threshold on the number of points (setting the parameter "Filter" to "CloudCapacityFilter").

After validation, you can use the Filter Data by Boolean Value Step to filter out point clouds that do not meet the requirements.

Parameter Description

Filter

Parameter description: Select the filter type used to validate the point clouds.

Value list:

  • CircleCloudsFilter: Filter based on whether the point cloud is contained in a circular region.

  • CloudCapacityFilter: Filter based on the number of points in the point cloud. Judge whether the point cloud meets the requirements by setting minimum and maximum point number thresholds.

  • RectCloudsFilter: Filter based on whether the point cloud is contained in a rectangular region.

  • SolidCloudsFilter: Filter based on whether the point cloud is contained in a solid region.

Default value: CloudCapacityFilter.

Instruction: Select different filter types according to different point cloud validation requirements.

Min Number of Points

Parameter description: Set the minimum number of points in a point cloud.
Default value: 6000.
Instruction: Point clouds with fewer points than this threshold will be judged as not meeting the requirements.

Max Number of Points

Parameter description: Set the maximum number of points in a point cloud.
Default value: 360000.
Instruction: Point clouds with more points than this threshold will be judged as not meeting the requirements.
