c# - 如何为 C# 窗口应用程序创建 opencv dll

Question

我需要将opencv(c/c++)程序转换成dll文件。我想在 c# windows 窗体应用程序中使用该 dll。

我尝试了一些网站给出的方法，但是在窗口窗体应用程序中添加引用时出现错误。

不知道哪里弄错了

A reference to “D:\WindowsFormApplication4\windowsForrmsApllications4\bin\debug\testdll.dll”
Could not be added. Please make sure that the file is accessible and that it is a valid assembly or COM Component

这里附上了我的示例代码。请帮助我。

Void  main(const char*filename)
{
if  (filename ==0)
    {
        printf("The image not loaded\n");
        return -1;
    }
    IplImage* input_im = 0; 
    input_im = cvLoadImage(filename);
    cvNamedWindow("InputImage",CV_WINDOW_AUTOSIZE);
    cvShowImage("InputImage",input_im);
    cvWaitKey(0);
    cvDestroyWindow("InputImage");
    cvReleaseImage(&input_im);

}

这有帮助吗？ http://www.emgu.com/wiki/index.php/Main_Page

Emgu CV is a cross platform .Net wrapper to the Intel OpenCV image processing library. Allowing OpenCV functions to be called from .NET compatible languages such as C#, VB, VC++, IronPython etc.

因为你的程序不大，完全可以用C#重写。
