Detailed Description

template<typename PointT>
class pcl::SampleConsensusModelCircle2D< PointT >

SampleConsensusModelCircle2D defines a model for 2D circle segmentation on the X-Y plane.

The model coefficients are defined as:

center.x : the X coordinate of the circle's center
center.y : the Y coordinate of the circle's center
radius : the circle's radius
