Detailed Description

A Class that provides common static functions used by all classes and tests in the anisotropic iterative closest point algorithm (AnisotropicIterativeClosestPointRegistration).

The class provides common functionality used by the A-ICP algorithm like: compute weightmatrices (CalculateWeightMatrix()), transform points (TransformPoints()), propagate 3 x 3 matrices (PropagateMatrices()) and compute the target registration error (TRE) (ComputeTargetRegistrationError()).

Member Function Documentation

CalculateWeightMatrix()

static WeightMatrix mitk::AnisotropicRegistrationCommon::CalculateWeightMatrix ( const CovarianceMatrix &  sigma_X, const CovarianceMatrix &  sigma_Y  )

static

Method that computes a WeightMatrix with two CovarianceMatrices.

Parameters

sigma_X	CovarianceMatrix from the moving point set.
sigma_Y	CovarianceMatrix from the fixed point set.

Returns

The computed WeighMatrix.

ComputeTargetRegistrationError()

static double mitk::AnisotropicRegistrationCommon::ComputeTargetRegistrationError ( const mitk::PointSet *  movingTargets, const mitk::PointSet *  fixedTargets, const Rotation &  rotation, const Translation &  translation  )

static

Compute the target registration error between two point sets.

Method that is used for testing and evaluation. It computes the target registration error (TRE) between two point sets with a rotation matrix and a translation vector.

Parameters

movingTargets	The target points of the moving point set.
fixedTargets	The target points of the fixed point set.
rotation	A 3x3 rotation matrix.
translation	A 3x1 translation vector.

Returns

The Target Registration Error (TRE).

PropagateMatrices()

static void mitk::AnisotropicRegistrationCommon::PropagateMatrices ( const MatrixList &  src, MatrixList &  dst, const Rotation &  rotation  )

static

Propagate a list of matrices with a rotation matrix.

Method that propagate the source list and saves the result in the destination. If the source and destination lists are the same the matrices will be computed in place.

Warning

No bound check is done. Make sure that both lists are allocated and have the same size.

Parameters

src	Reference to the source matrices list.
dst	Reference to the destination list
rotation	Reference to a rotation matrix.

TransformPoints()

static void mitk::AnisotropicRegistrationCommon::TransformPoints ( vtkPoints *  src, vtkPoints *  dst, const Rotation &  rotation, const Translation &  translation  )

static

Transforms a point cloud with a Rotation and Translation.

The method uses two point sets as input. It transforms every point from the source point set and saves the result in the destination. The source is not modified. If the same point set is used as source and destination. The method will modify the source and the transformation is done in place.

Warning

No bound check is done. Ensure that source and destination are allocated and have the same size.

Parameters

src	The source point set.
dst	The destination point set.
rotation	The rotation matrix.
translation	The translation vector.
