code: public static Point2D_F32 convertPixelToNorm(CameraModel param , Point2D_F32 pixel , Point2D_F32 norm ) {
  		return ImplPerspectiveOps_F32.convertPixelToNorm(param, pixel, norm);
  	}
docs: <p>
  Convenient function for converting from distorted image pixel coordinate to undistorted normalized
  image coordinates. If speed is a concern then {@link PinholePtoN_F32} should be used instead.
  </p>
  
  NOTE: norm and pixel can be the same instance.
  
  @param param Intrinsic camera parameters
  @param pixel Pixel coordinate
  @param norm Optional storage for output.  If null a new instance will be declared.
  @return normalized image coordinate
