我使用VISIONPRO 的版本为9.0；往往很多USB相机没有办法使用，我们可以采用拍图在文档下再同步抓取图片，再使用。
1.实现配置好CogImageFileTool工具，保存在文档中为img.vpp，步骤如下4步。
CogImageFileTool 序列化回来：
CogImageFileTool file1 = (CogImageFileTool)CogSerializer.LoadObjectFromFile(@"D:\AVI\img.vpp");
CogImageFileTool 运行很简单：
file1.Run();
图片显示：
cogRecordDisplay1.Image = file1.OutputImage;
CogImageConvert类为静态类使用（用的多我们用于灰图转换红色标注）
cogRecordDisplay1.Image = CogImageConvert.GetIntensityImage(file1.OutputImage, 0, 0, file1.OutputImage.Width, file1.OutputImage.Height);
原代码如下：
1 using System; 2 using System.Collections.Generic; 3 using System.ComponentModel; 4 using System.Data; 5 using System.Drawing; 6 using System.Linq; 7 using System.Text; 8 using System.Windows.Forms; 9 using Cognex.VisionPro; 10 using Cognex.VisionPro.ToolBlock; 11 using Cognex.VisionPro.ImageFile; 12 using System.IO; 13 using Cognex.VisionPro.OCRMax; 14 using Cognex.VisionPro.ID; 15 using System.Diagnostics; 16 using Cognex.VisionPro.PMAlign; 17 using Cognex.VisionPro.Blob; 18
19 namespace qj 20 { 21 public partial class Form1 : Form 22 { 23 public Form1() 24 { 25 InitializeComponent(); 26 chushua(); 27 } 28 CogAcqFifoTool camtool = null; 29 ICogFrameGrabber cam1 = null; 30 ICogAcqFifo cam = null; 31 // CogImageFile file = null;
32 CogImageFileTool file1 = null; 33 CogImageConvert covet1 = null; 34 private void chushua() 35 { 36 // camtool = new CogAcqFifoTool(); 37 // cam = camtool.Operator; 38 // covet1 = new CogImageConvert();
39 file1 = (CogImageFileTool)CogSerializer.LoadObjectFromFile(@"D:\AVI\img.vpp"); 40 file1.Run(); 41 // cogRecordDisplay1.Image = CogImageConvert.GetIntensityImage(file1.OutputImage, 0, 0, file1.OutputImage.Width, file1.OutputImage.Height);
42 cogRecordDisplay1.Image = file1.OutputImage; 43 } 44
45 private void button1_Click(object sender, EventArgs e) 46 { 47 // file1.Run();
48 cogRecordDisplay1.Image = CogImageConvert.GetIntensityImage(file1.OutputImage, 0, 0, file1.OutputImage.Width, file1.OutputImage.Height); 49 } 50 } 51 }
