使用openCVSharp在unity3d中转换IPLimage <> texture2d

Question

像主题说的那样。我正试图在unity3d中实现openCVSharp冲浪，并将其从iplimage转换为texture2d。另外考虑到这个转换过程应该至少在25fps下运行。所以任何提示或建议都非常有用！

Answer 1

可能是有点晚了，我工作的同样的事情，现在，这里是我的解决方案：

void IplImageToTexture2D (IplImage displayImg) 
{ 
    for (int i = 0; i < height; i++) 
    { 
     for (int j = 0; j < width; j++) 
     { 
      float b = (float)displayImg[i, j].Val0; 
      float g = (float)displayImg[i, j].Val1; 
      float r = (float)displayImg[i, j].Val2; 
      Color color = new Color(r/255.0f, g/255.0f, b/255.0f); 
      videoTexture.SetPixel(j, height - i - 1, color); 
     } 
    } 
    videoTexture.Apply(); 
} 

但它是一个有点慢。 仍在努力提高性能。

Texture2D tex = new Texture2D(640, 480); 
CvMat img = new CvMat(640, 480, MatrixType.U8C3); 

byte[] data = new byte[640 * 480 * 3]; 
Marshal.Copy(img.Data, data, 0, 640 * 480 * 3); 
tex.LoadImage(data);

为了提高性能使用Unity3d的无证功能LoadRawTextureData：

Texture2D IplImageToTexture2D(IplImage img) 
{ 
    Texture2D videoTexture = new Texture2D(imWidth, imHeight, TextureFormat.RGB24, false); 
    byte[] data = new byte[imWidth * imHeight * 3]; 
    Marshal.Copy(img.ImageData, data, 0, imWidth * imHeight * 3); 
    videoTexture.LoadRawTextureData(data); 
    videoTexture.Apply(); 
    return videoTexture; 
}
