I am doing it using checker board method and in python. I do not know if the value of camera constant C is correct or not.Could you tell me what range of values are got for C. Camera companies show focal length as 22-75mm...i am confused because of that.

Kindly help and ask for any more information as required.

If you speak of Camera Matrix, I had the same result and got pictures which were pretty correct once reprojected. Did you try to reproject (using undistort) and check the result is good?
