c++ - 无法读取图像 OpenCV

Question

我正在学习教程 here用于使用 Visual Studio 设置 OpenCV(我有 2013 社区版和 OpenCV 2.4.10)。

我有以下文件夹结构:

OpenCVTest

    -OpenCVTest.sln
    +x64
        +Debug
            - opencv_core2410d.dll
            - opencv_highgui2410d.dll
            - OpenCVTest.exe
            - OpenCVTest.ilk
            - OpenCVTest.pdb
            - feck.png

还有我的来源:

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

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
    if (argc != 2)
    {
        cout << " Usage: display_image ImageToLoadAndDisplay" << endl;
        return -1;
    }

    Mat image;
    image = imread(argv[1], IMREAD_COLOR); // Read the file

    if (!image.data) // Check for invalid input
    {
        cout << "Could not open or find the image" << std::endl;
        return -1;
    }

    namedWindow("Display window", WINDOW_AUTOSIZE); // Create a window for display.
    imshow("Display window", image); // Show our image inside it.

    waitKey(0); // Wait for a keystroke in the window
    return 0;
}

当我在 VS 或命令行中运行它时，出现以下错误:

C:\Users\mr\Documents\Visual Studio 2013\Projects\OpenCVTest\x64\Debug>OpenCVTest.exe feck.png
Could not open or find the image

有人知道为什么会这样吗？

更新

我试过给出完整路径:

image = imread("C:\Users\mr\Documents\Visual Studio 2013\Projects\OpenCVTest\feck.png", IMREAD_COLOR); // Read the file

并将图像与 .sln 文件放在同一层级，仍然没有成功。

Answer 1

像这样将您的图像放在 OpenCVTest 文件夹中:

C:\Users\mr\Documents\Visual Studio 2013\Projects\OpenCVTest\OpenCVTest\feck.png

-OpenCVTest.sln
-OpenCVTest <- **HERE**
-ipch
+x64
    +Debug
        - opencv_core2410d.dll
        - opencv_highgui2410d.dll
        - OpenCVTest.exe
        - OpenCVTest.ilk
        - OpenCVTest.pdb
        - feck.png
