Member Function Documentation

compute() [1/2]

bool vpgl_perspective_camera_compute::compute ( const std::vector< vgl_point_2d< double > > &  image_pts, const std::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

Returns

true if successful.

Definition at line 140 of file vpgl_camera_compute.cxx.

compute() [2/2]

bool vpgl_perspective_camera_compute::compute ( const std::vector< vgl_point_2d< double > > &  image_pts, const std::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 simpler than the general case above and only requires 4 points Put the resulting camera into camera

Returns

true if successful.

Parameters

ground_pts

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

compute_dlt()

bool vpgl_perspective_camera_compute::compute_dlt ( const std::vector< vgl_point_2d< double > > &  image_pts, const std::vector< vgl_point_3d< double > > &  world_pts, vpgl_perspective_camera< double > &  camera, double &  err  )

static

Uses the direct linear transform algorithm described in "Multiple.

View Geometry in Computer Vision" to find the projection matrix, and extracts the parameters of the camera from this projection matrix. Requires: image_pts and world_pts are correspondences. image_pts is the projected form, and world_pts is the unprojected form. There need to be at least 6 points.

Returns

true if successful. err is filled with the two-norm of the projection error vector. camera is filled with the perspective decomposition of the projection matrix.
