我使用JAI GigE Vision相机进行图像采集,但我想使用C#中的AForge Library进行图像分析,以创建独立于相机的解决方案。
Jai_FactoryWrapper.ImageInfo localImageInfo = new Jai_FactoryWrapper.ImageInfo();
image = (Bitmap)localImageInfo;
但它给出了一个错误:
Cannot convert type 'Jai_FactoryDotNET.Jai_FactoryWrapper.ImageInfo' to 'System.Drawing.Bitmap'
您能帮我解决如何将原始图像从相机转换为位图图像的问题吗?

以下是一个例子:
Bitmap image = GetBitmap((int)ImageInfo.SizeX, (int)ImageInfo.SizeY, 8, (byte*)ImageInfo.ImageBuffer);
其中GetBitmap
是:
public Bitmap GetBitmap(int nWidth, int nHeight, int nBpp, byte* DataColor)
{
Bitmap BitmapImage = new Bitmap(nWidth, nHeight, PixelFormat.Format24bppRgb);
BitmapData srcBmpData = BitmapImage.LockBits(new Rectangle(0, 0, BitmapImage.Width, BitmapImage.Height),
ImageLockMode.ReadWrite, BitmapImage.PixelFormat);
switch (BitmapImage.PixelFormat)
{
case PixelFormat.Format24bppRgb:
unsafe
{
byte* psrcBuffer = (byte*)srcBmpData.Scan0.ToPointer();
int nCount = srcBmpData.Width * srcBmpData.Height;
int nIndex = 0;
for (int y = 0; y < nCount; y++)
{
psrcBuffer[nIndex++] = DataColor[y];
psrcBuffer[nIndex++] = DataColor[y];
psrcBuffer[nIndex++] = DataColor[y];
}
}
break;
}
BitmapImage.UnlockBits(srcBmpData);
return BitmapImage;
}

如果有人需要它,我发现了一种更简单(更快)的方式:
internal static Bitmap convertToBitmap(Jai_FactoryDotNET.Jai_FactoryWrapper.ImageInfo ImageInfo)
{
Bitmap image = new Bitmap((int)ImageInfo.SizeX, (int)ImageInfo.SizeY, (int)ImageInfo.SizeX, System.Drawing.Imaging.PixelFormat.Format24bppRgb, ImageInfo.ImageBuffer);
return image;
}
