Detailed Description

The properties of a camera which affect the mapping between pixels in images and real world coordinates. May be used to interpret an input image or to generate an output image.

size()

cv::Size dewobble::Camera::size

(

)

const

Get the size of images produced by the camera

Returns

cv::Size

matrix()

cv::Matx33d dewobble::Camera::matrix

(

)

const

undistortPoints()

std::vector<cv::Point2f> dewobble::Camera::undistortPoints	(	std::vector< cv::Point2f >	points,
		cv::InputArray	rotation = cv::noArray(),
		cv::InputArray	output_matrix = cv::noArray()
	)		const

Convert a set of points in an image generated by the camera to points in a chosen camera matrix.

Parameters

points	The input points projected by this camera
rotation	Optional rotation to apply to the points in the world coordinate space
output_matrix	Optional output camera matrix. If not given, the identity matrix is used.

Returns

std::vector<cv::Point2f> The converted points projected by the output matrix

distortPoints()

std::vector<cv::Point2f> dewobble::Camera::distortPoints	(	std::vector< cv::Point2f >	points,
		cv::InputArray	input_matrix = cv::noArray()
	)		const

Map a set of points using the specified input matrix to their location as they would gbe projected by this camera.

Parameters

points	The input points projected by the input matrix
input_matrix	Optional input camera matrix. If not given, the identity matrix is used.

Returns

std::vector<cv::Point2f> The output points projected by this camera
