至於需要加那些dll，則看需求。

到目前為止，從環境的建置一直到建立專案完整的步驟都如上面所述。

五、调试测试

usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Windows.Forms;
usingEmgu.CV;
usingEmgu.Util;

namespaceEmguDemo
{
    public partial classForm1 : Form
    {
        publicForm1()
        {
            InitializeComponent();
        }

        private void button1_Click(objectsender, EventArgs e)
        {
            CvInvoke.cvNamedWindow("Hello");
            IntPtr img = CvInvoke.cvLoadImage("C:\1.jpg", Emgu.CV.CvEnum.LOAD_IMAGE_TYPE.CV_LOAD_IMAGE_ANYCOLOR);
            CvInvoke.cvShowImage("Hello", img);
            CvInvoke.cvWaitKey(0);
            CvInvoke.cvReleaseImage(refimg);
            CvInvoke.cvDestroyWindow("Hello");
        }
    }
}

是否安装了Microsoft Visual C++ 2010 SP1可再发行组件包x86,现在基本都带了，这个不是问题。

Have you copied theOpenCVdlls to the execution directory?

Make sure the unmanaged DLLs are in the execution directory.

• For EMGU CV version 2.4cudart64_42_9.dll, cvextern.dll, npp64_42_9.dll, opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_flannXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv_nonfreXXX.dll, opencv_objectdetectXXX.dll, opencv_videoXXX.dll,whereXXXis the OpenCV version number.

• For Emgu CV version >=2.4.2, this means the "x86" and "x64" folder and all the dlls within the folders. The folder names and file structures should not be altered when deploying with the application.

确认unmanaged DLLs 是否已经拷贝到程序文件夹。o(╯□╰)o 天生的缺陷。

• cudart64_32_16.dll
• cufft64_32_16.dll
• cvextern.dll
• npp64_32_16.dll
• opencv_calib3d220.dll
• opencv_contrib220.dll
• opencv_core220.dll
• opencv_features2d220.dll
• opencv_flann220.dll
• opencv_gpu220.dll
• opencv_highgui220.dll
• opencv_imgproc220.dll
• opencv_legacy220.dll
• opencv_ml220.dll
• opencv_objdetect220.dll
• opencv_video220.dll

具体dll文件列表可参考上述名称。

这步很重要，把相关dll拷贝过去就OK了。

The best way to set up your project is:

• Copy the unmanaged DLLs to your project folder
• Right click on the project, click Add->Existing Item and select all unmanaged DLLs. Add them to the project.
• For each of the included Dlls, left click on it, find the "Copy to Output Directory" option and select "Copy if newer"
