I am using 20 views of chessboard to calibrate camera and rectify images.I have tried changing images , and every time different rectified images were obtained(by changing views). I have been trying for many days but the images obtained are tilted and disparity map consists of a lot error pixels. How to fix it?

I am using python-opencv. I have obtained image like that:

Have you verified that the calibration you obtain is correct? See the advice at the bottom of this other answer for tips on how to do it.

  • I read this before! I am doing the same thing Martin Peris did for calibrating his camera.http://blog.martinperis.com/2011/08/stereo-vision-why-camera-calibration-is.html. It seems like it will get fixed at a particular set of images, the different images I take, different results are produced.Hope that it get fixed soon! – Maham Nov 06 '13 at 18:11
  • Even the unrectified images seem to be better than the rectified ones. – Maham Nov 06 '13 at 18:13
  • Have you any idea that is this the part of rectification process? (obtaining perspective transform of images, and then they get better) – Maham Nov 06 '13 at 18:16
