大恒IFrameData & IImageData转bmp & HObject & Mat

回调采集图像的数据类型为IFrameData，单帧采集的数据类型为IImageData，两者的区别为IImageData类多了一个**Destroy()**方法

C#

转为bmp格式

//黑白相机
public static Bitmap Tobmp(IImageData)
{
 int m_width = 服务器托管网(int)IImageData.GetWidth();
 int m_height = (int)IImageData.GetHeight();
 IntPtr pBufferMono = IImageData.GetBuffer();
 Bitmap bmp = new Bitmap(m_width, m_height, m_width, System.Drawing.Imaging.PixelFormat.Format8bppIndexed,pBufferMono);
 //添加调色板
 ColorPalette palette;
 palette = bmp.Palette;
 int i = 0;
 for (i = 0; i  255; i++)
    palette.Entries[i] = System.Drawing.Color.FromArgb(i, i, i);
 bmp.Palette = palette;
 return bmp;
}
//彩色相机
public static Bitmap Tobmp(IImageData)
{
 int m_width = (int)IImageData.GetWidth();
 int m_height = (int)IImageData.GetHeight();
 IntPtr pBufferColor = IImageData.ConvertToRGB24(GX_VALID_BIT_LIST.GX_BIT_0_7, GX_BAYER_CONVERT_TYPE_LIST.GX_RAW2RGB_NEIGHBOUR, false);
 Bitmap bmp = new Bitmap(m_width, m_height, m_width * 3, System.Drawing.Imaging.PixelFormat.Format24bppRgb, pBufferColor);
 return bmp;
}

转为Halcon的HObject格式

//黑白相机
public static HObject ToHObject(IImageData)
{
 int m_width = (int)IImageData.GetWidth();
 int m_height = (int)IImageData.GetHeight();
 HOperatorSet.GenImage1(out HObject ho_image, "byte", m_width, m_height,  IImageData.GetBuffer());
 return ho_image;
}
//彩色相机
public static HObject ToHObject(IImageData)
{
 int m_width = (int)IImageData.GetWidth();
 int m_height = (int)IImageData.GetHeight();
 IntPtr pBufferColor = IImageData.ConvertToRGB24(GX_VALID_BIT_LIST.GX_BIT_0_7, GX_BAYER_CONVERT_TYPE_LIST.GX_RAW2RGB_NEIGHBOUR, false);
 HOperatorSet.GenImageInterleaved(out HObject ho_image, pBufferColor, "bgr", m_height, m_height, -1, "byte", m_width, m_height, 0, 0, -1, 0);
 return ho_image;
}

转为OpenCVSharp的Mat格式

//黑白相机
public static Mat ToMat(IImageData)
{
 int height = (int)IImageData.GetHeight();
 int width = (int)IImageData.GetWidth();
 byte[] m_byMonoBuffer = new byte[width  * height];
 Marshal.Copy(IImageData.GetBuffer(), m_byMonoBuffer, 0, width * height);
 Mat image = new Mat(height, width, MatType.CV_8UC1, m_byMonoBuffer);   
 return image;  
}
//彩色相机
public static Mat ToMat(IImageData)
{
 int height = (int)IImageData.GetHeight();
 int width = (int)IImageData.GetWidth();
 IntPtr pBufferColor = IImageData.ConvertToRGB24(GX_VALID_BIT_LIST.GX_BIT_0_7, GX_BAYER_CONVERT_TYPE_LIST.GX_RAW2RGB_NEIGHBOUR, false);
 byte[] m_byColorBuffer = new byte[服务器托管网(width * 3) * height];
 Marshal.Copy(pBufferColor, m_byColorBuffer, 0, (width * 3) * height);
 Mat image = new Mat(height, width, MatType.CV_8UC3, m_byColorBuffer);  
 return image; 
}
