bool HMatrix2DComputeLinear::compute_p	(	PointArray const &	inpoints1,
		PointArray const &	inpoints2,
		HMatrix2D *	H
	)		`[protected, virtual]`

Compute a plane-plane projectivity using linear least squares.

Returns false if the calculation fails or there are fewer than four point matches in the list. The algorithm finds the nullvector of the $2 n \times 9$ design matrix:

$\left(\begin{array}{ccccccccc} 0 & 0 & 0 & x_1 z_1' & y_1 z_1' & z_1 z_1' & -x_1 y_1' & -y_1 y_1' & -z_1 y_1' \cr x_1 z_1' & y_1 z_1' & z_1 z_1' & 0 & 0 & 0 & -x_1 x_1' & -y_1 x_1' & -z_1 x_1' \cr \multicolumn{9}{c}{\cdots} \cr 0 & 0 & 0 & x_n z_n' & y_n z_n' & z_n z_n' & -x_n y_n' & -y_n y_n' & -z_n y_n'\cr x_n z_n' & y_n z_n' & z_n z_n' & 0 & 0 & 0 & -x_n x_n' & -y_n x_n' & -z_n x_n' \end{array}\right)$

If allow_ideal_points was set at construction, the $3 \times 9$ version which allows for ideal points is used.
