Detailed Description

template<typename PointSource, typename PointTarget, typename Scalar = float>
class pcl::registration::CorrespondenceEstimation< PointSource, PointTarget, Scalar >

CorrespondenceEstimation represents the base class for determining correspondences between target and query point sets/features.

Code example:

pcl::PointCloud<pcl::PointXYZRGBA>::Ptr source, target;
// ... read or fill in source and target
pcl::CorrespondenceEstimation<pcl::PointXYZ, pcl::PointXYZ> est;
est.setInputSource (source);
est.setInputTarget (target);
 
pcl::Correspondences all_correspondences;
// Determine all reciprocal correspondences
est.determineReciprocalCorrespondences (all_correspondences);
