Member Function Documentation

bool vpgl_perspective_camera_compute::compute	(	const vcl_vector< vgl_point_2d< double > > &	image_pts,
		const vcl_vector< vgl_point_3d< double > > &	world_pts,
		const vpgl_calibration_matrix< double > &	K,
		vpgl_perspective_camera< double > &	camera
	)		[static]

Compute from two sets of corresponding points.

Put the resulting camera into camera, return true if successful.

bool vpgl_perspective_camera_compute::compute	(	const vcl_vector< vgl_point_2d< double > > &	image_pts,
		const vcl_vector< vgl_point_2d< double > > &	ground_pts,
		vpgl_perspective_camera< double > &	camera
	)		[static]

Compute from two sets of corresponding 2D points (image and ground plane).

Parameters:

ground_pts

are 2D points representing world points with Z=0 The calibration matrix of camera is enforced This computation is simplier than the general case above and only requires 4 points Put the resulting camera into camera, return true if successful.

bool vpgl_perspective_camera_compute::compute	(	vpgl_rational_camera< double > const &	rat_cam,
		vgl_box_3d< double > const &	approximation_volume,
		vpgl_perspective_camera< double > &	camera,
		vgl_h_matrix_3d< double > &	norm_trans
	)		[static]

Compute from a rational camera.

Put the resulting camera into camera, return true if successful. The approximation volume defines the region of space (lon (deg), lat (deg), elev (meters)) where the perspective approximation is valid. Norm trans is a pre-multiplication of the perspective camera to account for scaling the lon, lat and elevation to the range [-1, 1]

bool vpgl_perspective_camera_compute::compute_local	(	vpgl_rational_camera< double > const &	rat_cam,

		vgl_h_matrix_3d< double > &	norm_trans
	)		[static]

Compute from rational camera using a local Euclidean coordinate system.
