Question

我使用OpenCV示例程序从我的相机计算相机矩阵和失真系数，并生成带有相关数据的xml文件。不，我想纠正从同一相机拍摄的一些图像中的失真。所以我创建程序但仍然有一些错误。我试图用它来获得不失真的图像。

这是我的代码

#include <iostream>
#include <sstream>
#include <string>
#include <ctime>
#include <cstdio>
#include <opencv2/core.hpp>
#include <opencv2/core/utility.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/calib3d.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/videoio.hpp>
#include <opencv2/highgui.hpp>
#include "cameracalibrator.h"

CameraCalibrator::CameraCalibrator() :
    flag(0),
    mustInitUndistort(true)
{
}

using namespace cv;
using namespace std;

int main(){
Mat src,gray,image;

Mat cameraMatrix = (Mat1d(3, 3) <<  8.5033354550764898e+002, 0, 640, 0, 8.5033354550764898e+002, 360, 0, 0, 1);
Mat distortionCoefficients = (Mat1d(1, 5) << -4.2796890539434634e-001, 2.8770882755049054e-001, 0, 0, -1.4405356460809188e-001);

// remove distortion in an image (after calibration)
cv::Mat CameraCalibrator::remap(const cv::Mat &image) {

    cv::Mat undistorted;
    cv::Mat image=imread("C:/Users/NTU/Desktop/Test/im4.png");

    if (mustInitUndistort) { // called once per calibration

        cv::initUndistortRectifyMap(
            cameraMatrix,  // computed camera matrix
            distCoeffs,    // computed distortion matrix
            cv::Mat(),     // optional rectification (none) 
            cv::Mat(),     // camera matrix to generate undistorted
//          cv::Size(640,480),
            image.size(),  // size of undistorted
            CV_32FC1,      // type of output map
            map1, map2);   // the x and y mapping functions

        mustInitUndistort= false;
    }

    // Apply mapping functions
    cv::remap(image, undistorted, map1, map2, 
        cv::INTER_LINEAR); // interpolation type

    return undistorted;

imshow("gg",undistorted);
while(uchar(waitKey(1))!='Q');
//return 0;
}
}

运行时遇到此错误：

error: qualified-id in declaration before '(' token
 cv::Mat CameraCalibrator::remap(const cv::Mat &image) {

任何帮助？

在相机校准后添加相机矩阵和失真系数时尝试获取未失真图像时出错
