Detailed Description

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

TransformationEstimationSVD implements SVD-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.
