Detailed Description

template<typename PointT, typename Scalar = float>
class pcl::registration::MetaRegistration< PointT, Scalar >

Meta Registration class.

Note
This method accumulates all registered points and becomes more costly with each registered point cloud.

This class provides a way to register a stream of clouds where each cloud will be aligned to the conglomerate of all previous clouds.

IterativeClosestPoint<PointXYZ,PointXYZ>::Ptr icp
( new IterativeClosestPoint<PointXYZ,PointXYZ>);
icp->setMaxCorrespondenceDistance (0.05);
icp->setMaximumIterations (50);
MetaRegistration<PointXYZ> mreg;
mreg.setRegistration (icp);
while ( true)
{
PointCloud<PointXYZ>::Ptr cloud ( new PointCloud<PointXYZ>);
read_cloud (*cloud);
mreg.registerCloud (cloud);
PointCloud<PointXYZ>::Ptr tmp ( new PointCloud<PointXYZ>);
transformPointCloud (*cloud, *tmp, mreg.getAbsoluteTransform ());
write_cloud (*tmp);

You have to set a valid registration object with setRegistration before using this
Parameters
[in] cloud point cloud to register
[in] delta_estimate estimated transform between last registered cloud and this one
Returns
true if registration converged
