Member Function Documentation

template<class T>

virtual vgl_homg_point_2d<T> vpgl_lens_distortion< T >::distort

(

const vgl_homg_point_2d< T > &

point

)

const [pure virtual]

Distort a projected point on the image plane.

Implemented in vpgl_radial_distortion< T >.

template<class T>

virtual void vpgl_lens_distortion< T >::set_translation	(	const vgl_vector_2d< T > &	offset,
		bool	after = true
	)		[pure virtual]

Set a translation to apply before of after distortion.

This is needed when distorting an image to translate the resulting image such that all points have positive indices

Implemented in vpgl_radial_distortion< T >.

template<class T >

vgl_homg_point_2d< T > vpgl_lens_distortion< T >::undistort	(	const vgl_homg_point_2d< T > &	point,
		const vgl_homg_point_2d< T > *	init = 0
	)		const [virtual]

Return the original point that was distorted to this location (inverse of distort).

Parameters:

init	is an initial guess at the solution for the iterative solver if init is NULL then point is used as the initial guess

Reimplemented in vpgl_radial_distortion< T >.
