Detailed Description

template<typename PointT, typename PointNT>
class pcl::PlaneCoefficientComparator< PointT, PointNT >

PlaneCoefficientComparator is a Comparator that operates on plane coefficients, for use in planar segmentation.

In conjunction with OrganizedConnectedComponentSegmentation, this allows planes to be segmented from organized data.

compare()

template<typename PointT , typename PointNT >

bool pcl::PlaneCoefficientComparator< PointT, PointNT >::compare	(	int	idx1,
		int	idx2
	)		const

inlineoverridevirtual

Compare points at two indices by their plane equations.

True if the angle between the normals is less than the angular threshold, and the difference between the d component of the normals is less than distance threshold, else false

Parameters
