C#（VS2010）调用HALCON12

C#（VS2010）调用HALCON12

参考自：http://www.cnblogs.com/hanzhaoxin/archive/2013/02/01/2888839.html

1、使用HDevelop编写代码:

dev_close_window ()
read_image (Image, 'E:/图库/abc.jpg')

rgb1_to_gray(Image,GrayImage)

get_image_size (Image, Width, Height)
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)
dev_display (Image)
[/code]



2、导出HALCON代码

选择HDevelop菜单栏中的“文件---->导出”，导出类型设为：C#-HALCON/.NET；选择导出到F盘中导出的文件为：sa.cs。



其导出的sa.cs代码为：

//
//  File generated by HDevelop for HALCON/DOTNET (C#) Version 12.0
//
//  This file is intended to be used with the HDevelopTemplate or
//  HDevelopTemplateWPF projects located under %HALCONEXAMPLES%\c#

using System;
using HalconDotNet;

public partial class HDevelopExport
{
public HTuple hv_ExpDefaultWinHandle;

// Main procedure
private void action()
{

// Local iconic variables

HObject ho_Image, ho_GrayImage;

// Local control variables

HTuple hv_Width = null, hv_Height = null;
// Initialize local and output iconic variables
HOperatorSet.GenEmptyObj(out ho_Image);
HOperatorSet.GenEmptyObj(out ho_GrayImage);

//dev_close_window(...);
ho_Image.Dispose();
HOperatorSet.ReadImage(out ho_Image, "E:/图库/abc.jpg");
ho_GrayImage.Dispose();
HOperatorSet.Rgb1ToGray(ho_Image, out ho_GrayImage);
HOperatorSet.GetImageSize(ho_GrayImage, out hv_Width, out hv_Height);
//dev_open_window(...);
HOperatorSet.DispObj(ho_GrayImage, hv_ExpDefaultWinHandle);
ho_Image.Dispose();
ho_GrayImage.Dispose();

}

public void InitHalcon()
{
// Default settings used in HDevelop
HOperatorSet.SetSystem("width", 512);
HOperatorSet.SetSystem("height", 512);
}

public void RunHalcon(HTuple Window)
{
hv_ExpDefaultWinHandle = Window;
action();
}

}

3、c#调用HALCON导出的程序

（1）新建一个C#应用窗体程序

（2）添加halcondotnet.dll文件到引用中，并将halconwindow添加至工具箱；

引用-添加引用-（找到halcon中的halcondotnet.dll进行添加）

其目录为：D:\Program Files\MVTec\HALCON-12.0\bin\dotnet35



（3）在工具箱中添加halconWindow控件

打开工具箱，在空白处右键-选择项-浏览，选择下边文件





（4）在Form1窗口添加一个button和halconWindow控件（工具箱中找halcon图标）.



（5）在Form1.cs中代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using HalconDotNet; //引入Halcon空间

namespace HALCON2
{
/*以下复制于sa.cs*/
public partial class HDevelopExport
{
public HTuple hv_ExpDefaultWinHandle;

// Main procedure
private void action()
{

// Local iconic variables

HObject ho_Image, ho_GrayImage;

// Local control variables

HTuple hv_Width = null, hv_Height = null;
// Initialize local and output iconic variables
HOperatorSet.GenEmptyObj(out ho_Image);
HOperatorSet.GenEmptyObj(out ho_GrayImage);

//dev_close_window(...);
ho_Image.Dispose();
HOperatorSet.ReadImage(out ho_Image, "E:/图库/abc.jpg");
ho_GrayImage.Dispose();
HOperatorSet.Rgb1ToGray(ho_Image, out ho_GrayImage);
HOperatorSet.GetImageSize(ho_GrayImage, out hv_Width, out hv_Height);
//dev_open_window(...);
HOperatorSet.DispObj(ho_GrayImage, hv_ExpDefaultWinHandle);
ho_Image.Dispose();
ho_GrayImage.Dispose();

}

public void InitHalcon()
{
// Default settings used in HDevelop
HOperatorSet.SetSystem("width", 512);
HOperatorSet.SetSystem("height", 512);
}

public void RunHalcon(HTuple Window)
{
hv_ExpDefaultWinHandle = Window;
action();
}

}
/*以上复制于sa.cs*/

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
HDevelopExport HD = new HDevelopExport();
HD.RunHalcon(hWindowControl1.HalconWindow);
}
}
}

运行结果：

另一种方法：
（1）将sa.cs导入C#工程:



（2）Form1.cs的代码修改为：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using HalconDotNet; //引入Halcon空间
namespace HALCON2
{public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
HDevelopExport HD = new HDevelopExport();
HD.RunHalcon(hWindowControl1.HalconWindow);
}
}
}

其运行结果为：
