Method Detail

clone

public RigidTransformModel3d clone()

Description copied from interface: EstimatableModel

Clone the model

Specified by:

clone in interface EstimatableModel<Point3d,Point3d>

Overrides:

clone in class AffineTransformModel3d

Returns:

a cloned copy

estimate

public boolean estimate(List<? extends IndependentPair<Point3d,Point3d>> data)

Description copied from interface: EstimatableModel

Estimates the model from the observations in the list of data. The data must contain at least EstimatableModel.numItemsToEstimate() pairs of dependent and independent data. It may contain more, in which case the estimate method may choose to make use of this data for validation, or obtaining a better model by a least squares method for example.

Specified by:

estimate in interface EstimatableModel<Point3d,Point3d>

Overrides:

estimate in class AffineTransformModel3d

Parameters:

data - Data with which to estimate the model

Returns:

true if a successful estimate was made, false otherwise

numItemsToEstimate

public int numItemsToEstimate()

Specified by:

numItemsToEstimate in interface EstimatableModel<Point3d,Point3d>

Overrides:

numItemsToEstimate in class AffineTransformModel3d

Returns:

The minimum number of observations required to estimate the model.
