Class AdjustHomographyMatrix

java.lang.Object

boofcv.alg.geo.h.AdjustHomographyMatrix

public class AdjustHomographyMatrix
extends Object

The scale and sign of a homography matrix is ambiguous. This contains functions which pick a reasonable scale and the correct sign. The second smallest singular value is set to one and the sign is chosen such that the basic properties work.

AdjustHomographyMatrix

public AdjustHomographyMatrix()

Method Detail

adjust

public boolean adjust(org.ejml.data.DenseMatrix64F H,
             AssociatedPair p)

adjust

public boolean adjust(org.ejml.data.DenseMatrix64F H,
             PairLineNorm p)

findScaleH

protected boolean findScaleH(org.ejml.data.DenseMatrix64F H)

The scale of H is found by computing the second smallest singular value.

adjustHomographSign

protected void adjustHomographSign(AssociatedPair p,
                       org.ejml.data.DenseMatrix64F H)

Since the sign of the homography is ambiguous a point is required to make sure the correct one was selected.

Parameters:

p - test point, used to determine the sign of the matrix.

adjustHomographSign

protected void adjustHomographSign(PairLineNorm p,
                       org.ejml.data.DenseMatrix64F H)

Since the sign of the homography is ambiguous a point is required to make sure the correct one was selected.

Parameters:

p - test point, used to determine the sign of the matrix.
