致命错误 LNK1104: 无法打开文件 'opencv_calib3d246.dll'

Question

我正在尝试运行 Visual C++ 与 OpenCV。我已将 OpenCV 链接到 Visual studio 2012。当我尝试运行代码时，它给我一个错误；

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

这是我试图做的事情：

#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。

还有什么需要补充的，还是需要在程序中初始化？

更新

我硬盘中OpenCV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 OPENCV_DIR，并将路径指定为 E:\opencv\opencv\build。而在 linker\command line

现在我无法加载图像。没有致命错误，什么也没有。它正在考虑 if 语句而不加载任何内容。

有什么建议吗？

Answer 1

您需要设置的不仅仅是链接器依赖项，您很可能错过了一个步骤。

我建议遵循 this 教程，因为它将帮助您完成设置。
