How to get the underlying corner detection uncertainty of findChessboardCorners

asked 2017-12-05 08:14:25 -0500

Is there a way to obtain the uncertainty (as a covariance matrix) for corner detector algorithms in OpenCV such as the Harris corner detection used by findChessboardCorners ? I need to take into account the chessboard corner detection uncertainty in my algorithm. I know the algorithm's covariance matrix for the corner position is given here in terms of its precision matrix. However, can this be returned somehow by the findChessboardCorners function?

Thanks
