当代码到达此行时，我在opencv中的面部识别器中获得访问冲突写入位置：model-> train（images，labels）;

错误：WHOMECamera.exe中0x00007FF9B494321B（opencv_core331.dll）的未处理异常：0xC0000005：访问冲突写入位置0x0000000100000014 . 发生了

#include <opencv2\opencv.hpp>
#include <opencv2\highgui.hpp>
#include <opencv2\objdetect.hpp>
#include <opencv2\core.hpp>
#include <opencv2\face.hpp>
#include <opencv2\imgcodecs.hpp>
#include <iostream>
#include <string>

using namespace std;
using namespace cv;
using namespace face;

int main(void)
{
    vector <Mat> images; // vector of matrix for the images of the faces;
    vector <int> labels; // vector of int's for the labes (each person get      label ex: moshe - 0);

    try
    {
        images.push_back(imread("D:\imagesForProject\1.jpg",    CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;

        images.push_back(imread("D:\imagesForProject\2.jpg", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;

        images.push_back(imread("D:\imagesForProject\3.jpg", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;


    }

    catch(Exception& e)
    {
        cerr << "can't open the images" << e.msg << endl; // if we couldn't     open the files cerr it's basic cout for errors;
    }

    Ptr<FaceRecognizer> model = FisherFaceRecognizer::create();
    model->train(images, labels);
    return(0);
}

    OpenCV 3.3 由我自己在 Ubuntu 16.04 上使用 G++ 5.4 建造 .

    这段代码适合我 . Do not ask me why ，你 should 找到差异 by yourself .

    #include <opencv2/opencv.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/objdetect.hpp>
#include <opencv2/core.hpp>
#include <opencv2/face.hpp>
#include <opencv2/imgcodecs.hpp>
#include <iostream>
#include <string>

using namespace std;
using namespace cv;
using namespace face;

int main(void)
{
    vector <Mat> images; // vector of matrix for the images of the faces;
    vector <int> labels; // vector of int's for the labes (each person get      label ex: moshe - 0);

    try{
        images.push_back(imread("Pictures/test0.png", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(0); // insert his label;
        images.push_back(imread("Pictures/test1.png", CV_LOAD_IMAGE_GRAYSCALE)); // insert the face image;
        labels.push_back(1); // insert his label;
    }catch(Exception& e){
        cerr << "can't open the images" << e.msg << endl; // if we couldn't     open the files cerr it's basic cout for errors;
    }

    Ptr<FaceRecognizer> model = FisherFaceRecognizer::create();
    model->train(images, labels);
    model->save("xxx.xml");
    return(0);
}
