opencv的拋出一個奇怪的錯誤運行一個簡單的程序

我編這個簡單的OpenCV代碼：opencv的拋出一個奇怪的錯誤運行一個簡單的程序

#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; 
}

然後我繼續運行它，但我得到這個奇怪的錯誤：

[email protected]:~/l33t/Secret Sharing$ g++ -g -I /usr/local/boost CreateShares.cpp -o createShares `pkg-config --cflags --libs opencv` 
[email protected]:~/l33t/Secret Sharing$ ./createShares

    what(): /build/buildd/opencv-2.3.1/modules/core/src/array.cpp:2482: error: (-206) Unrecognized or unsupported array type in function cvGetMat

我粘貼gdb輸出直到出錯幫助你分析：

(gdb) next

任何想法這裏有什麼可能是錯誤的？我的代碼有什麼問題，或者opencv出了問題，或者我沒有在某處放置一些opencv路徑，或者opencv安裝不正確？我沒有想法。請幫幫我！

在我的系統，當我運行它工作得很好，只要我改變路徑是我的系統上的圖像節目。如果我沒有提供一個實際存在的圖像的路徑，那麼我得到一個像你顯示的錯誤。 – 2013-02-23 16:29:24

當您按頻道分割圖像時，您將每個頻道分配給'CoreImageB'而不是相應的頻道。因此，你的'CoreImageR'和'CoreImageG'保持空白，這可能會導致'imshow'行爲不當。 – 2013-02-23 16:32:19

謝謝。 – Chani 2013-02-23 16:32:40

這是一個數據類型不匹配的問題
