Cv2FindHomography Method (IEnumerablePoint2d, IEnumerablePoint2d, HomographyMethods, Double, OutputArray)

computes the best-fit perspective transformation mapping srcPoints to dstPoints.

Namespace:  OpenCvSharp
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 3.4.1.20180605-33-CaRLSharp
Syntax
public static Mat FindHomography(
	IEnumerable<Point2d> srcPoints,
	IEnumerable<Point2d> dstPoints,
	HomographyMethods method = HomographyMethods.None,
	double ransacReprojThreshold = 3,
	OutputArray mask = null
)

Parameters

srcPoints
Type: System.Collections.GenericIEnumerablePoint2d
Coordinates of the points in the original plane
dstPoints
Type: System.Collections.GenericIEnumerablePoint2d
Coordinates of the points in the target plane
method (Optional)
Type: OpenCvSharpHomographyMethods
Method used to computed a homography matrix.
ransacReprojThreshold (Optional)
Type: SystemDouble
Maximum allowed reprojection error to treat a point pair as an inlier (used in the RANSAC method only)
mask (Optional)
Type: OpenCvSharpOutputArray
Optional output mask set by a robust method ( CV_RANSAC or CV_LMEDS ). Note that the input mask values are ignored.

Return Value

Type: Mat
