how to set the valid camera distortion parameter in gazebo

I want to do some calibration with gazebo. When I change the camera distortion parameter, the image of gazebo camera has no obvious distortion, and I collect some images to do calibration with OpenCV, the calibration results of distortion are almost 0,and they have great difference from the parameters that I set . Is there something wrong?What should I do ? Thank you very much!
