cvFindEssentialMat

Module:	OpenCV

Calculates an essential matrix from the corresponding points in two images.

Name	Type	Description
inPoints1	Point2D Array
inPoints2	Point2D Array
inCameraMatrix	Matrix
inMethod	CvEstimateAffine2DMethod
inProbability	Double	Parameter specifies a desirable level of confidence (probability) that the estimated matrix is correct.
inThreshold	Double	Parameter used for RANSAC. It is the maximum distance from a point to an epipolar line in pixels, beyond which the point is considered an outlier and is not used for computing the final fundamental matrix. It can be set to something like 1-3, depending on the accuracy of the point localization, image resolution, and the image noise.
outEssentialMatrix	Matrix
