According to : http://docs.opencv.org/master/d9/d0c/group__calib3d.html
The distortion coefficients do not depend on the scene viewed. Thus, they also belong to the intrinsic camera parameters. And they remain the same regardless of the captured image resolution. If, for example, a camera has been calibrated on images of 320 x 240 resolution, absolutely the same distortion coefficients can be used for 640 x 480 images from the same camera while fx, fy, cx, and cy need to be scaled appropriately.
