opencv - fatal error LNK1104 : cannot open file 'opencv_calib3d246.dll'

Question

我正在尝试使用 OpenCV 运行 Visual C++。我已将 OpenCV 链接到 Visual Studio 2012。当我尝试运行代码时，它给了我一个错误；

LINK : fatal error LNK1104: cannot open file 'opencv_calib2d246.dll'

这是我想做的:

#include "stdafx.h"
#include "opencv2\highgui\highgui.hpp"
#include "opencv2\core\core.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],CV_LOAD_IMAGE_UNCHANGED);

    if(! image.data)
    {
        cout<<"couldn't open or find the image"<<endl;
        return -1;
    }

    namedWindow("Display Window",WINDOW_AUTOSIZE);
    imshow("Display Window",image);

    waitKey(0);
    return 0;
}

我已经包含了所有的库。我在 Windows 7 32 位系统上使用 OpenCV 2.4.6。

我还需要添加什么，还是必须在程序中初始化它？

更新

OpenCV在我硬盘的路径:E:\opencv\opencv。系统环境变量中的路径:%OPENCV_DIR%\x86\vc11\bin;，我在其中创建了一个新变量作为 OPENCV_DIR 并将路径指定为 E:\opencv\opencv\构建。在 linker\command line

中

现在我无法加载图像。没有 fatal error ，什么也没有。它正在考虑 if 语句并且不加载任何内容。

有什么建议吗？

您需要设置的不仅仅是链接器依赖项，而且您很可能错过了一个步骤。

我建议关注 this教程，因为它将帮助您完成设置。
