Detailed Description

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

SampleConsensusModelPerpendicularPlane defines a model for 3D plane segmentation using additional angular constraints.

The plane must be perpendicular to an user-specified axis (setAxis), up to an user-specified angle threshold (setEpsAngle). The model coefficients are defined as:

a : the X coordinate of the plane's normal (normalized)
b : the Y coordinate of the plane's normal (normalized)
c : the Z coordinate of the plane's normal (normalized)
d : the fourth Hessian component of the plane's equation

Code example for a plane model, perpendicular (within a 15 degrees tolerance) with the Z axis:

SampleConsensusModelPerpendicularPlane<pcl::PointXYZ> model (cloud);
model.setAxis (Eigen::Vector3f (0.0, 0.0, 1.0));
model.setEpsAngle (pcl::deg2rad (15));

Note: Please remember that you need to specify an angle > 0 in order to activate the axis-angle constraint!
