Hi, I have two cameras. I calibrated them separately but i couldn't achieve stereo calibration. Here is my example pictures:

  1. Left Distorted: image description
  2. Right Distorted: image description
  3. Left Unistorted: image description
  4. Right Unistorted: image description
  5. Left Stereo: image description
  6. Right Stereo: image description

Do you have any advices? What can be the problem?

please try again with the images:

  • put them here, not link to an external bin, where those will expire.
  • edit you question, and use the "upload image" button.

I edit the images. Thanks for the advice

things to try:

  • get a larger chessboard (your camera seems ~2m away)
  • try to cover the corners of the image better (most distortion is there)
  • check the rms return value from stereocalibrateCamera(), if it's more than 0.5, try again with better images

again, this IS painful, and usually needs several attempts to get right, so don't give up early !
