Detailed Description

template<typename PointSource, typename PointTarget, typename MatScalar = float>
class pcl::registration::TransformationEstimationLM< PointSource, PointTarget, MatScalar >

TransformationEstimationLM implements Levenberg Marquardt-based estimation of the transformation aligning the given correspondences.

Note
The class is templated on the source and target point types as well as on the output scalar of the transformation matrix (i.e., float or double). Default: float.

◆ computeDistance() [1/2]

template<typename PointSource , typename PointTarget , typename MatScalar = float>
virtual MatScalar pcl::registration::TransformationEstimationLM< PointSource, PointTarget, MatScalar >::computeDistance ( const PointSource &  p_src,
const PointTarget &  p_tgt 
) const
inlineprotectedvirtual

Compute the distance between a source point and its corresponding target point.

Parameters
[in]p_srcThe source point
[in]p_tgtThe target point
Returns
The distance between p_src and p_tgt
Note
Older versions of PCL used this method internally for calculating the optimization gradient. Since PCL 1.7, a switch has been made to the computeDistance method using Vector4 types instead. This method is only kept for API compatibility reasons.

Reimplemented in pcl::registration::TransformationEstimationPointToPlane< PointSource, PointTarget, Scalar >, pcl::registration::TransformationEstimationPointToPlane< PointSource, PointTarget, float >, and pcl::registration::TransformationEstimationPointToPlane< PointSource, PointTarget, MatScalar >.

◆ computeDistance() [2/2]

virtual MatScalar pcl::registration::TransformationEstimationLM< PointSource, PointTarget, MatScalar >::computeDistance ( const Vector4 p_src,
const PointTarget &  p_tgt 
) const
inlineprotectedvirtual

Compute the distance between a source point and its corresponding target point.

Parameters
[in]p_srcThe source point
[in]p_tgtThe target point
Returns
The distance between p_src and p_tgt
Note
A different distance function can be defined by creating a subclass of TransformationEstimationLM and overriding this method. (See TransformationEstimationPointToPlane)

Reimplemented in pcl::registration::TransformationEstimationPointToPlane< PointSource, PointTarget, float >, and pcl::registration::TransformationEstimationPointToPlane< PointSource, PointTarget, MatScalar >.
