Unity + OpenCVSharp2 - WebcamTexture

1. OpenCVSharp CvCapture  사용

화면이 뒤집혀서 나오는데 원인은 모르겠음

    public Material mat;
    private Texture2D dstTexture;
    private OpenCVUnity Convert = new OpenCVUnity();
    IplImage dst;
    IplImage capture;
 
    private CvCapture cvCapture;
    CvSize size = new CvSize(640, 480);
 
    private void Start()
    {
        cvCapture = CvCapture.FromCamera(0);
        cvCapture.SetCaptureProperty(CaptureProperty.FrameWidth, 640);
        cvCapture.SetCaptureProperty(CaptureProperty.FrameHeight, 480);
 
        capture = new IplImage(size.Width, size.Height, BitDepth.U8, 3);
        dst = new IplImage(size.Width, size.Height, BitDepth.U8, 3);
        dstTexture = new Texture2D(size.Width, size.Height, TextureFormat.RGB24, false);
 
    }
 
 
    private void Update()
    {
        capture = cvCapture.QueryFrame();
        Cv.CvtColor(capture, dst, ColorConversion.BgrToRgb);       
        dstTexture.LoadRawTextureData(dst.ImageData, size.Width * size.Height * 3);
        dstTexture.Apply();
 
    }
 
    private void OnDestroy()
    {
        dst.Dispose();
        capture.Dispose();
    }

 

2. Unity WebcamTexture 사용

이전프레임, 현재프레임 필요할때

    public Material mat;
    WebCamTexture camTexture;
    private Texture2D dstTexture;
    private OpenCVUnity Convert = new OpenCVUnity();
    IplImage prev;
    IplImage curr;
    IplImage dst;
 
    private CvCapture cvCapture;
 
    private void Start()
    {
        WebCamDevice device = WebCamTexture.devices[0];
        camTexture = new WebCamTexture(device.name);
        camTexture.Play();
 
        if (camTexture.didUpdateThisFrame)
        {
            curr = WebcamTex2Ipl(camTexture);
        }
         dstTexture = new Texture2D(camTexture.width, camTexture.height, TextureFormat.RGBA32, false);
    }
 
    private void Update()
    {
        if (curr != null) prev = curr;
        if (camTexture.didUpdateThisFrame)
        {
            curr = WebcamTex2Ipl(camTexture);
 
            dst = Convert.OpticalFlowPyrLK(prev, curr);           
            dstTexture.LoadRawTextureData(dst.ImageData, camTexture.width * camTexture.height * 4);
            dstTexture.Apply();
            mat.mainTexture = dstTexture;
        }
    }
 
    IplImage WebcamTex2Ipl(WebCamTexture wct)
    {
        Color32[] camTex32 = wct.GetPixels32();
        CvSize size = new CvSize(wct.width, wct.height);
        return IplImage.FromPixelData(size, BitDepth.U8, 4, camTex32);
    }
 
 
    private void OnDestroy()
    {
        curr.Dispose();
        dst.Dispose();
        prev.Dispose();
    }
