C++ Opencv运行简单程序时抛出一个奇怪的错误

我编译了以下简单的opencv代码：

#include "opencv2/core/core.hpp"        
#include "opencv2/highgui/highgui.hpp"  
#include <boost/random.hpp>
#include <ctime>
#include <time.h>
#include <stdlib.h>
#include <math.h>
#include <iostream>

/*Compile using 

g++ -I /usr/local/boost CreateShares.cpp -o createShares `pkg-config --cflags --libs opencv` 

*/
using namespace cv;

class CreateShares
{
private:
    cv::Mat CoreImage;

    cv::Mat CoreImageR;
    cv::Mat CoreImageG;
    cv::Mat CoreImageB; 

    cv::Mat share0;
    cv::Mat share1;
    cv::Mat share2;
    cv::Mat share3;

public:
    CreateShares();
    CreateShares(std::string path);

    void showCoreImage();
    void showCoreImageR();
    void showCoreImageG();
    void showCoreImageB();

};

CreateShares::CreateShares()
{

}

CreateShares::CreateShares(std::string path)
{
    CoreImage = cv::imread(path, 1);

    if (CoreImage.empty())
    {
        std::cout<<"Could not read image !"<<std::endl;
        return;
    }
    std::vector<cv::Mat> temp_mat_vector; 
    cv::split(CoreImage, temp_mat_vector);

    //CoreImageB = (temp_mat_vector[0]).clone();
    temp_mat_vector[0].copyTo(CoreImageB);
    temp_mat_vector[1].copyTo(CoreImageB);
    temp_mat_vector[2].copyTo(CoreImageB);


}

void CreateShares::showCoreImage()
{
    cv::namedWindow("Core Image", WINDOW_AUTOSIZE);
    cv::imshow("Core Image", CoreImage);
}

void CreateShares::showCoreImageR()
{
    cv::namedWindow("Core Image R", WINDOW_AUTOSIZE);
    cv::imshow("Core Image R", CoreImageR);
}

void CreateShares::showCoreImageG()
{
    cv::namedWindow("Core Image G", WINDOW_AUTOSIZE);
    cv::imshow("Core Image G", CoreImageG);
}

void CreateShares::showCoreImageB()
{
    cv::namedWindow("Core Image B", WINDOW_AUTOSIZE);
    cv::imshow("Core Image B", CoreImageB);
}

int main()
{
    std::string path = "/home/r/l33t/Secret Sharing/nature.jpg";

    CreateShares* cs = new CreateShares(path);
    cs->showCoreImage();

    return 0;
}

我正在粘贴gdb输出，直到出现错误，以帮助您分析：

你知道这里有什么问题吗？我的代码是否有问题，或者opencv是否有问题，或者我是否没有在某个地方包含某些opencv路径，或者opencv是否没有正确安装？我没有主意了。请帮帮我

这是一个数据类型不匹配的问题

在我的系统上，当我运行程序时，只要我将路径更改为系统上的映像，它就可以正常工作。如果我没有提供实际存在的图像的路径，则会出现如您所示的错误。当您按通道分割图像时，您会将每个通道分配给

CoreImageB

而不是相应的通道。因此，您的

CoreImageR

和

CoreImageG

保持为空，这可能会导致

imshow

行为不当。谢谢。我把这条路径搞砸了。另外，你可以说

CoreImageB=temp\u mat\u vector[0]，等等@SchighSchagh实际上是赋值操作符wwas给了我错误，所以我不得不切换到copyto和clone。但让我检查一下你指出的空洞问题。
