Detailed Description

This class wraps intrinsic parameters of a camera.

It provides several constructors that can extract the intrinsic parameters from field of view, intrinsic matrix and projection matrix. :

Constructor & Destructor Documentation

Camera() [1/4]

cv::viz::Camera::Camera	(	double	fx,
		double	fy,
		double	cx,
		double	cy,
		const Size &	window_size
	)

Constructs a Camera.

Parameters

fx	Horizontal focal length.
fy	Vertical focal length.
cx	x coordinate of the principal point.
cy	y coordinate of the principal point.
window_size	Size of the window. This together with focal length and principal point determines the field of view.

Camera() [2/4]

cv::viz::Camera::Camera ( const Vec2d &  fov, const Size &  window_size  )

explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

fov	Field of view (horizontal, vertical)
window_size	Size of the window. Principal point is at the center of the window by default.

Camera() [3/4]

cv::viz::Camera::Camera ( const Matx33d &  K, const Size &  window_size  )

explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

K	Intrinsic matrix of the camera.
window_size	Size of the window. This together with intrinsic matrix determines the field of view.

Camera() [4/4]

cv::viz::Camera::Camera ( const Matx44d &  proj, const Size &  window_size  )

explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

proj	Projection matrix of the camera.
window_size	Size of the window. This together with projection matrix determines the field of view.
