Constructor & Destructor Documentation

cv::viz::WCameraPosition::WCameraPosition

(

double

scale = 1.0

)

Creates camera coordinate frame at the origin.

Camera coordinate frame

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

Display the viewing frustum.

Parameters

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

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

Camera viewing frustum

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

Display the viewing frustum.

Parameters

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

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

Camera viewing frustum

cv::viz::WCameraPosition::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.

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.

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

Camera viewing frustum with image

cv::viz::WCameraPosition::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.

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.

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