我正在尝试将 EMGUCV 用于 C#。目前我已经安装了 Visual Studio 2010 express Edition。当尝试执行一些简单的命令时Emgu.CV.CvInvoke
抛出异常,所以我将非托管代码放在 exe 文件夹中。但它仍然继续给我错误。所以我尝试将非托管代码添加到解决方案资源管理器中,但它仍然给我这个错误。还有什么我可以做的,以便我最终可以使用 emguCV 吗?
例外是
System.TypeInitializationException was unhandled
Message=The type initializer for 'Emgu.CV.CvInvoke' threw an exception.
有堆栈跟踪:

我只执行一些简单的代码:
public partial class Form1 : Form
{
private Capture capture;
private bool captureInProgress;
public Form1()
{
InitializeComponent();
}
private void ProcessFrame(Object sender, EventArgs args )
{
Image<Bgr, Byte> ImageFrame = capture.QueryFrame();
CamImageBox1.Image = ImageFrame;
}
private void camButton_Click(object sender, EventArgs e)
{
if (capture == null)
{
try
{
capture = new Capture();
}
catch (NullReferenceException excpt)
{
MessageBox.Show(excpt.Message);
}
}
if (capture != null)
{
if (captureInProgress)
{
camButton.Text = "start";
}
else
{
camButton.Text = "stop";
Application.Idle += ProcessFrame;
}
captureInProgress = !captureInProgress;
}
}
private void ReleaseData()
{
if (capture != null)
{
capture.Dispose();
}
}
emguCV 的示例可以在我的计算机上运行。非常感谢阿德里安
