class ProgressiveSampleConsensus< PointT >

Detailed Description

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

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

The plane must be parallel to a user-specified axis (setAxis) within an user-specified angle threshold (setEpsAngle).

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

 SampleConsensusModelParallelPlane<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!
