OpenCV错误:“无法加载图片！" [英] OpenCV error: "Cannot load image!"

问题描述

在编译OpenCV的源并将Windows 7和VS2010配置为正确链接库之后，我能够编译以下代码:

After compiling OpenCV's source and configuring Windows 7 and VS2010 to link the libraries correctly, I was able to compile the following code:

#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);
}

即使正确指定了路径，我也无法获得此代码来显示lena图像.这里的代码有什么问题吗?

Even though the path is correctly specified I can't get this code to show the lena image. Is there anything wrong with the code here?

尽管代码可以编译，但这是构建时的完整输出:

推荐答案

尝试以下代码:

#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. 尝试使用最新的Opencv 2.4.3
2. 链接适当的库
3. 正确添加包含路径
4. 将bin文件夹的路径添加到环境变量路径
