C# OpenCvSharp 将 mat 转换为 ndarray

Question

我有以下代码可以获取我电脑的实时网络摄像头。

这很好用，但我想做的是将

Mat

转换为

NdArray

。我尝试了多种方法，但似乎找不到解决方案。

代码如下：

public partial class Form1 : Form
    {
        VideoCapture capture;
        Mat frame;
        Bitmap image;
        private Thread camera;
        int isCameraRunning = 0;

        public Form1()
        {
            InitializeComponent();

        }

        private void Form1_Load(object sender, System.EventArgs e)
        {

        }

        private void btnStreamOnOff_Click(object sender, System.EventArgs e)
        {
            if (btnStreamOnOff.Text.Equals("Start Streaming"))
            {
                CaptureCamera();
                btnStreamOnOff.Text = "Stop Streaming";
                isCameraRunning = 1;
            }
            else
            {
                capture.Release();
                btnStreamOnOff.Text = "Start Streaming";
                isCameraRunning = 0;
            }

        }

        private void CaptureCamera()
        {
            camera = new Thread(new ThreadStart(CaptureCameraCallback));
            camera.Start();
        }
        private void CaptureCameraCallback()
        {
            frame = new Mat();
            capture = new VideoCapture(0);
            //capture.Open(2);
            while (isCameraRunning == 1)
            {
                capture.Read(frame);
                image = BitmapConverter.ToBitmap(frame);
                picStream.Image = image;
                image = null;
            }
        }
    }

这是我第一次尝试将 Mat 转换为 NdArray：

Mat frameMat = capture.RetrieveMat();
var graymat = frameMat.CvtColor(ColorConversionCodes.BGR2GRAY);
graymat.GetArray(out byte[] plainArray);
NDarray nDarray = np.array(plainArray, dtype: np.uint8); 
Debug.WriteLine(nDarray);

但是我遇到以下错误：

DllNotFoundException: Could not load python311.dll.
Win32Exception: %1 is not a valid Win32 application
System.TypeInitializationException: 'The type initializer for 'Delegates' threw an exception.'

希望有人能帮我破译这个
