Struct Camera

Source
pub struct Camera { /* private fields */ }
Expand 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. :

Implementations§

impl Camera

Source

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.
Source

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.
Source

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 block formula
  • window_size: Size of the window. This together with intrinsic matrix determines the field of view.
Source

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 block formula

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

Source

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.

impl<Mat> ModifyInplace for Mat
where Mat: Boxed,

Source§

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res, ) -> Res

Helper function to call OpenCV functions that allow in-place modification of a Mat or another similar object. By passing a mutable reference to the Mat to this function your closure will get called with the read reference and a write references to the same Mat. This is unsafe in a general case as it leads to having non-exclusive mutable access to the internal data, but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold. Read more
