Detailed Description

Holds the view of a virtual camera, to a plane, for which images from other viewpoints can be added. These images will be projected onto the plane. This can be used e.g. for Birds-eye views.

		const ::Eigen::Isometry3f &	cam2plane,
		const Eigen::Matrix3f &	camMat
	)

		const Eigen::Vector3f &	n,
		float	dist
	)		const

◆ calcHomography() [3/3]

Eigen::Matrix3f Homography::calcHomography	(	const Eigen::Isometry3f &	camA2plane,
		const Eigen::Isometry3f &	camB2plane
	)		const

Calculate the homography transform between two cameras, for which the transform to a common reference is given. The xy plane of the reference frame is used as the projection surface.

Parameters

camA2plane	- current frame
camB2plane	- desired frame

Returns: homography which transforms current to desired frame

◆ clearVirtualImage()

void Homography::clearVirtualImage ( )

clear the virtual image

◆ getVirtualImage()

cv::Mat Homography::getVirtualImage ( )

Returns: cv::Mat object of the virtual camera view

◆ init()

void Homography::init	(	int	rows,
		int	cols,
		float	focal,
		const Eigen::Isometry3f &	vcam2plane
	)

Initialize virtual camera
