SLAMflex SE  0.1.0
SLAMflex provides detection and tracking of dominant planes for smartphone devices. This plane can then be used to show AR content relative to the plane orientation. The detection of plane is performed in the field of view of the smartphone camera. In subsequent frames it is tracked. The interface returns the plane position and orientation.

Detailed Description

template<int Rows = Dynamic, int Cols = Rows, class Precision = double>
class TooN::QR_Lapack< Rows, Cols, Precision >

Performs QR decomposition.

Warning
this will only work if the number of columns is greater than the number of rows!

The QR decomposition operates on a matrix A. It can be performed with or without column pivoting. In general:

\[ AP = QR \]

Where $P$ is a permutation matrix constructed to permute the columns of A. In practise, $P$ is stored as a vector of integer elements.

With column pivoting, the elements of the leading diagonal of $R$ will be sorted from largest in magnitude to smallest in magnitude.

Constructor & Destructor Documentation

template<int Rows = Dynamic, int Cols = Rows, class Precision = double>
template<int R, int C, class P , class B >
TooN::QR_Lapack< Rows, Cols, Precision >::QR_Lapack ( const Matrix< R, C, P, B > &  m,
bool  p = 0 
)
inline

Construct the QR decomposition of a matrix. This initialises the class, and performs the decomposition immediately.

Parameters
mThe matrix to decompose
pWhether or not to perform pivoting
