VisionPro 编写二维码识别Quickbuild工程

编写作业如图所示，本文采用的是读取本地二维码，由于没有相机所以只能够选择读取本地二维码。

当然需要利用Cog2DSymbolTool1工具对二维码进行训练。

C#脚本代码中添加变量：

 private Cog2DSymbolTool Cog2DSymbolToolObject; 2  private string DecodedString;

C#脚本构造函数GroupRun中添加如下代码：

Cog2DSymbolToolObject = (Cog2DSymbolTool) toolGroup.Tools["Cog2DSymbolTool1"]; 2     DecodedString = Cog2DSymbolToolObject.Result.DecodedString; 3     
MessageBox.Show("二维码解码信息：" + DecodedString);  //用于弹出对话框

C#脚本构造函数ModifyLastRunRecord添加代码如下：

public override void ModifyLastRunRecord(Cognex.VisionPro.ICogRecord lastRecord) 2  { 3     CogGraphicLabel ResultLabel = new CogGraphicLabel(); 4     ResultLabel.SetXYText(300 / 2, 300 / 2, DecodedString); 5     ResultLabel.Color = Cognex.VisionPro.CogColorConstants.Blue; 6     toolGroup.AddGraphicToRunRecord(ResultLabel,lastRecord,"Image Source.OutputImage","script"); 7   }

完成代码如下：

using System;  2 using System.Windows.Forms;  3 using Cognex.VisionPro;  4 using Cognex.VisionPro3D;  5 using Cognex.VisionPro.ToolGroup;  6 using Cognex.VisionPro.TwoDSymbol;  7

  // The GroupRun function is called when the tool group is run. The default 14   // implementation provided here is equivalent to the normal behavior of the 15   // tool group. Modifying this function will allow you to change the behavior 16   // when the tool group is run.
  public override bool GroupRun(ref string message, ref CogToolResultConstants result) 18  { 19     // To let the execution stop in this script when a debugger is attached, uncomment the following lines. 20     // #if DEBUG 21     // if (System.Diagnostics.Debugger.IsAttached) System.Diagnostics.Debugger.Break(); 22     // #endif 23  
    // Run each tool in the tool group using the RunTool function
    for (Int32 toolIdx = 0; toolIdx < toolGroup.Tools.Count; toolIdx++) 26       toolGroup.RunTool(toolGroup.Tools[toolIdx], ref message, ref result); 27     
    Cog2DSymbolToolObject = (Cog2DSymbolTool) toolGroup.Tools["Cog2DSymbolTool1"]; 29     DecodedString = Cog2DSymbolToolObject.Result.DecodedString; 30     
    MessageBox.Show("二维码解码信息：" + DecodedString); 32  
    // Returning False indicates we ran the tools in script, and they should not be 34     // run by VisionPro 
    return false; 36  } 37

#region "When the Last Run Record is Created"
  // Allows you to add or modify the contents of the last run record when it is 46   // created. For example, you might add custom graphics to the run record here.
  public override void ModifyLastRunRecord(Cognex.VisionPro.ICogRecord lastRecord) 48  { 49     CogGraphicLabel ResultLabel = new CogGraphicLabel(); 50     ResultLabel.SetXYText(300 / 2, 300 / 2, DecodedString); 51     ResultLabel.Color = Cognex.VisionPro.CogColorConstants.Blue; 52     toolGroup.AddGraphicToRunRecord(ResultLabel,lastRecord,"Image Source.OutputImage","script"); 53  } 54 #endregion

  // Perform any initialization required by your script here

    base.Initialize(host); 62  } 63 #endregion
