Detailed Description

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

SampleConsensusModelNormalParallelPlane defines a model for 3D plane segmentation using additional surface normal constraints.

Basically this means that checking for inliers will not only involve a "distance to model" criterion, but also an additional "maximum angular deviation" between the plane's normal and the inlier points normals. In addition, the plane normal must lie parallel to an user-specified axis.

The model coefficients are defined as:

To set the influence of the surface normals in the inlier estimation process, set the normal weight (0.0-1.0), e.g.:

SampleConsensusModelNormalPlane<pcl::PointXYZ, pcl::Normal> sac_model;
...
sac_model.setNormalDistanceWeight (0.1);
...

In addition, the user can specify more constraints, such as:

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