Struct opencv::viz::Camera

pub struct Camera { /* private fields */ }

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. :

Implementations

impl Camera

pub fn new( fx: f64, fy: f64, cx: f64, cy: f64, window_size: Size ) -> Result<Camera>

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.

pub fn new_1(fov: Vec2d, window_size: Size) -> Result<Camera>

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.

Overloaded parameters

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

pub fn new_2(k: Matx33d, window_size: Size) -> Result<Camera>

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.

Overloaded parameters

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

pub fn new_3(proj: Matx44d, window_size: Size) -> Result<Camera>

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.

Overloaded parameters

• proj: Projection matrix of the camera with the following form

• window_size: Size of the window. This together with projection matrix determines the field of view.

pub fn kinect_camera(window_size: Size) -> Result<Camera>

Creates a Kinect Camera with

• fx = fy = 525
• cx = 320
• cy = 240

Parameters

• window_size: Size of the window. This together with intrinsic matrix of a Kinect Camera determines the field of view.
