calibration with wide baseline using opencv library

[stereopsis]

Dear all,

I had a problem when I used opencv library for calibrating with wide baseline.
I can not obtain rectified map using for rectify two images come from left and right cameras although opencv libraray can detect all corners of the chessboard.

I read the document of opencv, they said that we can not using the library for calibrating with wide baseline (the algorithm is not support for this case).
Have you met this problem like me? Please share your experiments to me.

I'm looking forward to receive your reply.
