I have performed single camera calibration using openCV library before performing stereo calibration and,
results of single camera calibration are:

focal length of camera 1 is: fx=1.2462718254982949e+003, fy=1.2462718254982949e+003 , with avg reprojection error=3.3547184378077333e-001

focal length of camera 2 is:fx= 1.6148973771889357e+003, fy=1.6148973771889357e+003 with avg reprojection error=3.4419465826561280e-001

Is this difference is permissible for a stereo camera and With these focal lengths can i get a good depth estimation after stereo calibration and rectification?

    I'm voting to close this question as off-topic because it's about optics, not programming. – MSalters Jun 22 '16 at 06:58
  • its about image processing using opencv library in C++, then how can u say its not programming @MSalters – lipi Jun 22 '16 at 07:20
  • The question is also written in English, still doesn't make it on-topic for English.SE either. "Focal lengths" simply are a concept in optics, not in C++. – MSalters Jun 22 '16 at 07:24
  • i have tagged the question in opencv and 3d reconstruction category not in C++ and those who have knowledge about the topic can understand my question. – lipi Jun 22 '16 at 07:37
