C#与VisionPro联合编程

本文主要是介绍C#与VisionPro联合编程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 参照康耐视提供的样例

C:\Program Files\Cognex\VisionPro\samples\Programming\QuickBuild\EfficientApp\C#

C:\Program Files\Cognex\VisionPro\samples\Programming\QuickBuild\mySavedQB.vpp

2. 参照样例写一个

1. 创建工程

创建一个Windows窗体应用程序（.NET Framework）

2. 添加引用

懒得一个一个分辨了，我全都添加进来。

同时，下面这两句不能落下：

using Cognex.VisionPro;
using Cognex.VisionPro.QuickBuild;

3. 声明变量

        //定义变量CogJobManager m_jobManager;CogJob m_job;CogJobIndependent m_jobIndependent;

4. 初始化

            //初始化m_jobManager = (CogJobManager)CogSerializer.LoadObjectFromFile(@"C:\Program Files\Cognex\VisionPro\samples\Programming\QuickBuild\mySavedQB.vpp");m_job = m_jobManager.Job(0);m_jobIndependent = m_job.OwnedIndependent;

5. 刷新队列

            //刷新队列m_jobManager.UserQueueFlush();m_jobManager.FailureQueueFlush();m_job.ImageQueueFlush();m_jobIndependent.RealTimeQueueFlush();

6. 用户数据获取

            //结果处理m_jobManager.UserResultAvailable += M_jobManager_UserResultAvailable;

        private void M_jobManager_UserResultAvailable(object sender, CogJobManagerActionEventArgs e){//用户代码ICogRecord topRecord = m_jobManager.UserResult();ICogRecord tmp = topRecord.SubRecords[@"Tools.Item[""CogBlobTool1""].CogBlobTool.Results.GetBlobs().Count"];//throw new NotImplementedException();}private void ButtonRunOnce_Click(object sender, EventArgs e){try{m_jobManager.Run();}catch (Exception ex){MessageBox.Show(ex.Message);//throw;}           }

已发送项：

当上一次处理没有完成，就又立即点击运行按钮，就会出现下列异常。

当然了，我们可以使用try catch语句来抛出异常

7. 跨线程访问Windows控件–委托

delegate void UserResultDelegate(object sender, CogJobManagerActionEventArgs e);

        //用户可用的事件处理程序private void M_jobManager_UserResultAvailable(object sender, CogJobManagerActionEventArgs e){if (InvokeRequired){BeginInvoke(new UserResultDelegate(M_jobManager_UserResultAvailable), new object[] { sender, e });return;}//用户代码ICogRecord topRecord = m_jobManager.UserResult();ICogRecord tmp = topRecord.SubRecords[@"Tools.Item[""CogBlobTool1""].CogBlobTool.Results.GetBlobs().Count"];//throw new NotImplementedException();int count = (int)tmp.Content;textBoxCount.Text = count.ToString();}

8. 显示图像

放置一个checkbox控件
修改以下几个参数

        private void CheckBoxRunContinue_CheckedChanged(object sender, EventArgs e){if (checkBoxRunContinue.Checked){try{m_jobManager.RunContinuous();}catch (Exception ex){MessageBox.Show(ex.Message);}buttonRunOnce.Enabled = false;}else{try{m_jobManager.Stop();}catch (Exception ex){MessageBox.Show(ex.Message);}buttonRunOnce.Enabled = true;}}

9. 释放资源

        private void Form1_FormClosed(object sender, FormClosedEventArgs e){//窗口关闭m_jobManager.UserResultAvailable -= M_jobManager_UserResultAvailable;//取消事件关联cogRecordDisplay1.Dispose();m_jobManager.Shutdown();}

3. 代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Cognex.VisionPro;
using Cognex.VisionPro.QuickBuild;namespace FirstVP
{delegate void UserResultDelegate(object sender, CogJobManagerActionEventArgs e);public partial class Form1 : Form{//定义变量CogJobManager m_jobManager;CogJob m_job;CogJobIndependent m_jobIndependent;public Form1(){InitializeComponent();}private void Form1_Load(object sender, EventArgs e){//初始化m_jobManager = (CogJobManager)CogSerializer.LoadObjectFromFile(@"C:\Program Files\Cognex\VisionPro\samples\Programming\QuickBuild\mySavedQB.vpp");m_job = m_jobManager.Job(0);m_jobIndependent = m_job.OwnedIndependent;//刷新队列m_jobManager.UserQueueFlush();m_jobManager.FailureQueueFlush();m_job.ImageQueueFlush();m_jobIndependent.RealTimeQueueFlush();//结果处理m_jobManager.UserResultAvailable += M_jobManager_UserResultAvailable;}//用户可用的事件处理程序private void M_jobManager_UserResultAvailable(object sender, CogJobManagerActionEventArgs e){if (InvokeRequired){BeginInvoke(new UserResultDelegate(M_jobManager_UserResultAvailable), new object[] { sender, e });return;}//用户代码ICogRecord topRecord = m_jobManager.UserResult();ICogRecord tmpRecord = topRecord.SubRecords[@"Tools.Item[""CogBlobTool1""].CogBlobTool.Results.GetBlobs().Count"];//throw new NotImplementedException();int count = (int)tmpRecord.Content;textBoxCount.Text = count.ToString();//显示图像tmpRecord = topRecord.SubRecords["ShowLastRunRecordForUserQueue"];tmpRecord = tmpRecord.SubRecords["LastRun"];tmpRecord = tmpRecord.SubRecords["Image Source.OutputImage"];cogRecordDisplay1.Record = tmpRecord;cogRecordDisplay1.Fit(true);}private void ButtonRunOnce_Click(object sender, EventArgs e){try{m_jobManager.Run();}catch (Exception ex){MessageBox.Show(ex.Message);//throw;}           }private void CheckBoxRunContinue_CheckedChanged(object sender, EventArgs e){if (checkBoxRunContinue.Checked){try{m_jobManager.RunContinuous();}catch (Exception ex){MessageBox.Show(ex.Message);}buttonRunOnce.Enabled = false;}else{try{m_jobManager.Stop();}catch (Exception ex){MessageBox.Show(ex.Message);}buttonRunOnce.Enabled = true;}}private void Form1_FormClosed(object sender, FormClosedEventArgs e){//窗口关闭m_jobManager.UserResultAvailable -= M_jobManager_UserResultAvailable;//取消事件关联cogRecordDisplay1.Dispose();m_jobManager.Shutdown();}}
}
