Constructor & Destructor Documentation

◆ vpgl_calibration_matrix() [1/3]

template<class T >

vpgl_calibration_matrix< T >::vpgl_calibration_matrix ( )

Default constructor makes an identity matrix.

Destructor.

◆ vpgl_calibration_matrix() [2/3]

template<class T>

vpgl_calibration_matrix< T >::vpgl_calibration_matrix	(	T	focal_length,
		const vgl_point_2d< T > &	principal_point,
		T	x_scale = `(T)1`,
		T	y_scale = `(T)1`,
		T	skew = `(T)0`
	)

Construct using all of the camera parameters.

Must satisfy the following requirements: x,y_scales must be > 0, focal_length must be not equal to 0.

Definition at line 33 of file vpgl_calibration_matrix.hxx.

◆ vpgl_calibration_matrix() [3/3]

template<class T>

vpgl_calibration_matrix< T >::vpgl_calibration_matrix ( const vnl_matrix_fixed< T, 3, 3 > & K )

Construct from a right upper triangular matrix whose decomposition into the calibration components makes sense.

The supplied matrix can be a scalar multiple of such a matrix.
