Hello Sabrina,
IMHO, this is perfectly normal in the context of stereography. As you say, it is due to the quadratic interpolation done by stereo_image_proc.
Have a look at chapter 12 of the book "learning openCV", it explains this process. In the main line, the problem is that there is a nonlinear relationship between the disparity (distance in pixel between left and right image) and the real distance.
Did you try following this tutorial on tuning stereo_proc parameters?
Hope it helps
