Detailed Documentation

This 3D Widget represents camera position in a scene by its axes or viewing frustum. :

Construction

WCameraPosition(double scale = 1.0)

Creates camera coordinate frame at the origin.

WCameraPosition(
    const Matx33d& K,
    double scale = 1.0,
    const Color& color = Color::white()
    )

Display the viewing frustum.

Creates viewing frustum of the camera based on its intrinsic matrix K.

Parameters:

K	Intrinsic matrix of the camera.
scale	Scale of the frustum.
color	Color of the frustum.

WCameraPosition(
    const Vec2d& fov,
    double scale = 1.0,
    const Color& color = Color::white()
    )

Display the viewing frustum.

Creates viewing frustum of the camera based on its field of view fov.

Parameters:

fov	Field of view of the camera (horizontal, vertical).
scale	Scale of the frustum.
color	Color of the frustum.

WCameraPosition(
    const Matx33d& K,
    InputArray image,
    double scale = 1.0,
    const Color& color = Color::white()
    )

Display image on the far plane of the viewing frustum.

Creates viewing frustum of the camera based on its intrinsic matrix K, and displays image on the far end plane.

Parameters:

K	Intrinsic matrix of the camera.
image	BGR or Gray-Scale image that is going to be displayed on the far plane of the frustum.
scale	Scale of the frustum and image.
color	Color of the frustum.

WCameraPosition(
    const Vec2d& fov,
    InputArray image,
    double scale = 1.0,
    const Color& color = Color::white()
    )

Display image on the far plane of the viewing frustum.

Creates viewing frustum of the camera based on its intrinsic matrix K, and displays image on the far end plane.

Parameters:

fov	Field of view of the camera (horizontal, vertical).
image	BGR or Gray-Scale image that is going to be displayed on the far plane of the frustum.
scale	Scale of the frustum and image.
color	Color of the frustum.
