cvFindEssentialMat


Module: OpenCV

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

Name Type Range Description
Input value inPoints1 Point2DArray
Input value inPoints2 Point2DArray
Input value inCameraMatrix Matrix
Input value inMethod CvEstimateAffine2DMethod
Input value inProbability Double Parameter specifies a desirable level of confidence (probability) that the estimated matrix is correct.
Input value 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.
Output value outEssentialMatrix Matrix
