RemoveOutliersFromPoint3DGrid


Header: FIL.h
Namespace: fil
Module: Vision3DPro

Removes noise from a given Point3DGrid. All points that are too far from their neighbors are removed.

Syntax

C++
C#
 
void fil::RemoveOutliersFromPoint3DGrid
(
	const fil::Point3DGrid& inPointGrid,
	ftl::Optional<const fil::Region&> inRoi,
	const float inStdDevMultiple,
	const int inNeighborCount,
	fil::Point3DGrid& outGrid,
	float& diagThreshold,
	float& diagAverageDistance
)

Parameters

Name Type Range Default Description
Input value
 inPointGrid const Point3DGrid& Input Point3DGrid
Input value
 inRoi Optional<const Region&> NIL Region of interest
Input value
 inStdDevMultiple const float 0.0 - 1.5f Allows to set a threshold based on standard deviation of average distances between points on input.
Input value
 inNeighborCount const int 1 - 10 Defines number of neighbors used to compute average distances between vertices.
Output value
 outGrid Point3DGrid& Cleaned input
Diagnostic input
 diagThreshold float& Threshold used by the algorithm.
Diagnostic input
 diagAverageDistance float& Average distance between input points and their neighborhood
