Detailed Description

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

Incremental IterativeClosestPoint class.

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

IterativeClosestPoint<PointXYZ,PointXYZ>::Ptr icp
 (new IterativeClosestPoint<PointXYZ,PointXYZ>);
icp->setMaxCorrespondenceDistance (0.05);
icp->setMaximumIterations (50);
 
IncrementalRegistration<PointXYZ> iicp;
iicp.setRegistration (icp);
 

while (true){
 PointCloud<PointXYZ>::Ptr cloud (new PointCloud<PointXYZ>);
 read_cloud (*cloud);
 iicp.registerCloud (cloud);
 
 PointCloud<PointXYZ>::Ptr tmp (new PointCloud<PointXYZ>);
 transformPointCloud (*cloud, *tmp, iicp.getAbsoluteTransform ());
 write_cloud (*tmp);
}

getAbsoluteTransform()

template<typename PointT , typename Scalar >

pcl::registration::IncrementalRegistration< PointT, Scalar >::Matrix4 pcl::registration::IncrementalRegistration< PointT, Scalar >::getAbsoluteTransform

inline

Get estimated overall transform.

Definition at line 91 of file incremental_registration.hpp.

getDeltaTransform()

template<typename PointT , typename Scalar >

pcl::registration::IncrementalRegistration< PointT, Scalar >::Matrix4 pcl::registration::IncrementalRegistration< PointT, Scalar >::getDeltaTransform

inline

Get estimated transform between the last two registered clouds.

Definition at line 84 of file incremental_registration.hpp.

registerCloud()

template<typename PointT , typename Scalar >

bool pcl::registration::IncrementalRegistration< PointT, Scalar >::registerCloud	(	const PointCloudConstPtr &	cloud,
		const Matrix4 &	delta_estimate = `Matrix4::Identity()`
	)

Note: You have to set a valid registration object with setRegistration before using this; The class doesn't copy cloud. If you afterwards change cloud, that will affect this class.
