用MVS   SDK采集的图片的数据格式是：

  IntPtr imageBuffer = IntPtr.Zero;
  int width, height, chanles;
  GetImage(out width, out height, out chanles, out imageBuffer);

如果我们在得到图片数据后，需要用到VM的算子开发。我们需要把图片生成为CMvdImage：

我们需要：

CMvdImage InputImage = new CMvdImage();

MVD_IMAGE_DATA_INFO imageDataStruct = new MVD_IMAGE_DATA_INFO();

imageDataStruct.stDataChannel[0].nRowStep = Convert.ToUInt32(width);

imageDataStruct.stDataChannel[0].nLen = Convert.ToUInt32(width * height);

imageDataStruct.stDataChannel[0].nSize = Convert.ToUInt32(width * height);

 //IntPtr 转 byte[]   
int size = Convert.ToInt32(width * height);
byte[] managedArray = new byte[size];
Marshal.Copy(imageBuffer, managedArray, 0, size);
imageDataStruct.stDataChannel[0].arrDataBytes = managedArray;
InputImage.InitImage((uint)width, (uint)height, VisionDesigner.MVD_PIXEL_FORMAT.MVD_PIXEL_MONO_08, imageDataStruct);

InputImage.SaveImage("E:\\百度网盘下载\\3.bmp");   //保存图片测试

这就图像数据转换成功了。

延伸课题：-------------------如果我们得到byte[]数据，怎么转为IntPtr呢----------------------------

下面提供一种方法：

IntPtr  IntPtr_=ArrToPtr(managedArray);

具体方法为：

 IntPtr ArrToPtr(byte[] array)
{
return System.Runtime.InteropServices.Marshal.UnsafeAddrOfPinnedArrayElement(array, 0);
}

然后可以进行测试转换是否成功：

HOperatorSet.GenImage1(out image, "byte", width, height, ArrToPtr(managedArray));
HOperatorSet.WriteImage(image, "jpg", 0, "E:\\百度网盘下载\\2.jpg");

查看本地图片效果：---->图片一样，说明转换成功。

所有的测试程序为：

using System.ComponentModel;

int i = 0;
foreach (var item in cams)
{

if (cams[0].GetImage(out width, out height, out chanles, out imageBuffer))
{

HOperatorSet.WriteImage(image, "jpg", 0, "E:\\百度网盘下载\\1.jpg");

//另外备注一下 byte[] 转 IntPtr
HOperatorSet.GenImage1(out image, "byte", width, height, ArrToPtr(managedArray));
