分享一下我老師大神的人工智慧教程!零基礎,通俗易懂!http://blog.csdn.net/jiangjunshow
也歡迎大家轉載本篇文章。分享知識,造福人民,實現我們中華民族偉大復興!
1. 從http://sourceforge.net/projects/emgucv/?source=directory下載最新的Emgu CV2.4.2
2. 將libemgucv-windows-x86-gpu-2.4.2.1777拷貝到D:\soft\Emgu2.4.2資料夾下,執行此.exe檔案,將其安裝到D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777資料夾下,安裝完後會自動重啟;
3. 將D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin;D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin\x86(
4. 開啟vs2008,新建一個基於Windows窗體的應用程式;
5. 匯入UI外掛:Tool-->Choose Toolbox Items-->.NET Framework Components-->點選Browse,選中D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin
6. 新增引用:選中工程下的References-->Add Reference-->Browse選中D:\soft\Emgu2.4.2\emgucv-windows-x86-gpu2.4.2.1777\bin下的Emgu.CV.dll、Emgu.CV.ML.dll、 Emgu.CV.UI.dll、 Emgu.Util.dll、ZedGraph.dll 5個動態庫,點選OK;
7. 點選Solution Platforms-->Configuration Manager:Active solution platform將原來的Any CPU改為x86,否則會提示“Emgu.CV.CvInvoke的型別初始值設定項引發異常”的錯誤。
網上的一個程式碼示例,編譯、執行成功:
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Windows.Forms;
usingEmgu.CV;//Emgu
usingEmgu.CV.Structure;
usingEmgu.Util;
usingSystem.Threading;
namespaceTestEmgu
{
public partial class Form1 : Form
{
publicForm1()
{
InitializeComponent();
}
privateCapturecapture;
privateboolcaptureinprocess;//判斷攝像頭的狀態
privatevoidbutton1_Click(objectsender,EventArgse)
{
if(capture !=null)
{
if(captureinprocess)
{
Application.Idle -=newEventHandler(processframe);
button1.Text ="stop!";
}
else
{
Application.Idle +=newEventHandler(processframe);
button1.Text ="start!";
}
captureinprocess= !captureinprocess;
}
else//攝像頭為空,則通過Capture()方法呼叫
{
try
{
capture=newCapture();
}
catch(NullReferenceExceptionexcpt)
{
MessageBox.Show(excpt.Message);
}
}
}
privatevoidprocessframe(objectsender,EventArgsarg)
{
Image<Bgr,Byte>frame =capture.QueryFrame();
imageBox1.Image =frame;
}
}
}
