Oh I see, I somehow missed this paragraph in the documentation.

Now it works, though it does not make sense to me. However, thank you very much!

Sorry I don't understand what you are saying. How is it possible not to use different images for each camera?

Thank you for your response!

I don't think the images are the problem. With the ones provided by OpenCV the result is even worse. Besides, the "normal" calibrate function works perfectly.

The stereo camera is custom made, but we paid much attention to the parallel alignment of the cameras. Also I thought, the distortion coefficients for each camera are computed independently of each other, aren't they?

I am using 52 images from each camera with the chessboard in nearly every possible position and orientation. I am afraid, for privacy reasons, I can't post the images, because they are not my property.

Hi, I wanted to calibrate my camera system using the SteroCalibrate function and then undistort the images. But the undistort function rather returns extremely distorted images, which is not the case when I calibrate each camera seperately. The strange thing is, I get the same distorted images with the "official" OpenCV sample program.

I guess, it won't be a problem to calibrate each camera itself and then compute the projection matrices with the stereoRectify function, but how do I get the translation vector T?
