I am trying to call cv::fisheye::undistortImage for removing distortion from image but in the compilation time its showing fisheye not declared in this scope . How to resolve this error?

#include <iostream>
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
#include "opencv2/calib3d/calib3d.hpp"

using namespace std;
using namespace cv;
using namespace fisheye;

int main (int argc, const char * argv[]){

    Mat img;
    img = imread(argv[1]);   // Read the file
    Mat new_image;
    /// creating cameramatrix
    Mat cameraMatrix = Mat::zeros(3, 3, CV_64F);
    Mat distCoeff = Mat::zeros(1, 8, CV_64F);
    distCoeff.at<double>(0,0) = -0.3682;
    distCoeff.at<double>(0,1) = 0.2848;
