OpenCV錯誤：「無法加載圖像！」

Question

編譯的OpenCV的源代碼和配置Windows 7和VS2010正確鏈接庫後，我就能夠編譯下面的代碼：

#include <opencv2/highgui/highgui.hpp> 
#include <iostream> 

using namespace cv; 
using namespace std; 
int main() 
{ 
    Mat im = imread("C:\projects\cvtest3\lena.jpg"); // this *is* the proper path, I'm sure 

    if (im.empty()) 
    { 

     cout << "Cannot load image!" << endl; 
       while (true){} 
     return -1; 
    } 
    imshow("Image", im); 
    waitKey(0); 
} 

即使正確指定的路徑我不能得到這個代碼顯示萊娜形象。這裏的代碼有什麼問題嗎？

雖然代碼編譯，這是完整的輸出，同時建設：

Answer 1

試試這個代碼：

#include <opencv2/highgui/highgui.hpp> 
#include <opencv2/core/core.hpp> 
#include <opencv2/imgproc/imgproc.hpp> 

using namespace std; 
using namespace cv; 

int main() 
{ 
    Mat image = imread("C:\\projects\\cvtest3\\lena.jpg"); 
    if(image.empty()) 
    return -1; 
    imshow("TEST",image); 
    waitKey(); 

    return 0; 
} 

1. 嘗試使用的是2.4.3
2. 最新的OpenCV鏈接正確的庫
3. 正確添加包含路徑
4. 將bin文件夾的路徑添加到環境變量路徑
