Fix documentation for findEssentialMat to reflect how it actually works. #25488
Documentation for findEssentialMat() incorrectly states that the method uses the same cameraMatrix for both lists of points even though there are two cameraMatrix and distCoeffs.
Checked the code and it does the right thing i.e. uses cameraMatrix1, distCoeffs1 for points1 and cameraMatrix2, distCoeffs2 for points2.
Updated the documentation for the method to clarify what it does. The code itself is not changed.
