2. Bayer图转彩色图并显示在自定义控件上
下面是将C# Bayer图像变量 转为halcon图像变量的方法，如果需要，可以按照下面的方式修改。这种转换会比较方便，如果拆通道会比较麻烦，这里就不介绍了。//在pictrue控件上显示图像Invoke(new MethodInvoker(delegate (){stDisplayInfo.hWnd = pictureBox1.Handle;}));stDisplayInfo.pData = m_BufForDriver;stDisplayInfo.nDataLen = stFrameInfo.nFrameLen;stDisplayInfo.nWidth = stFrameInfo.nWidth;stDisplayInfo.nHeight = stFrameInfo.nHeight;stDisplayInfo.enPixelType = stFrameInfo.enPixelType;//m_MyCamera.MV_CC_DisplayOneFrame_NET(ref stDisplayInfo);//这里是将图像显示在picture控件上byte[] m_pImageData = new byte[(int)stDisplayInfo.nDataLen];Marshal.Copy(stDisplayInfo.pData, m_pImageData, 0, (int)stDisplayInfo.nDataLen);unsafe{fixed (byte * pImage = m_pImageData){//C# 变量转为 Halcon 图像变量HOperatorSet.GenImage1Extern(out ho_BImageBayer, "byte", stDisplayInfo.nWidth, stDisplayInfo.nHeight, new IntPtr(pImage), 0);//将Bayer图转为彩色图HOperatorSet.CfaToRgb(ho_BImageBayer, out ho_BImageRGB1, "bayer_gb", "bilinear");}}//显示try{zcHWindow1.SetImage(ho_BImageRGB1);//这里是我自己写的自定义控件，并不是Halcon自带的}catch{}
