Detailed Description

The 3-d offset and scale parameters of rational cameras typically must be adjusted to compensate for errors in geographic alignment.

This algorithm adjusts these parameters to give the smallest projection error. That is, the error between the true image location and the projected 3-d world point corresponding to that location.

Constructor & Destructor Documentation

vpgl_adjust_lsqr()

vpgl_adjust_lsqr::vpgl_adjust_lsqr	(	vpgl_rational_camera< double > const &	rcam,
		std::vector< vgl_point_2d< double > > const &	img_pts,
		std::vector< vgl_point_3d< double > >	geo_pts,
		unsigned	num_unknowns,
		unsigned	num_residuals
	)

Constructor.

Note

image points are not homogeneous because require finite points to measure projection error

Member Function Documentation

f()

void vpgl_adjust_lsqr::f ( vnl_vector< double > const &  x, vnl_vector< double > &  fx  )

overridevirtual

The main function.

Given the parameter vector x, compute the vector of residuals fx. fx has been sized appropriately before the call.

Implements vnl_least_squares_function.
