前言

Halcon是一种计算机视觉软件工具，用于图像处理、分析和机器视觉应用。它由德国MVTec公司开发，是一种功能强大的视觉软件工具，可用于解决各种计算机视觉问题，包括目标检测、图像识别、三维视觉等。Halcon支持多种编程语言，包括C++、C#、Python等，用户可以使用自己熟悉的编程语言进行开发和应用。

HALCON 主要提供的技术有：条形码和二维码读取、BLOB 分析、物图像分类、计算光学成像、过滤技术、缺陷检查、匹配、1D/2D/3D 测量、形态学处理、OCR 和 OCV、基于样本的识别（SBI）、亚像素边缘检测和线条提取技术、深度学习和 3D 视觉技术。

详细的软件安装教程可以看：https://codeboy.blog.csdn.net/article/details/129848407

一、.NET6与Halcon编程环境构建

1、新建WPF应用程序完成后，解决方案资源管理器——引用处右键，添加引用如下两个dll（只引入第一个也可以）

2、在MainWindow添加halcon

二、WPF中使用Halcon插件展示加载图片

1、添加加载图片按钮和方法

using HalconDotNet;
using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace _2_LoadImage
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
/// <summary>
/// 加载图片的按钮事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Btn_LoadImage_Click(object sender, RoutedEventArgs e)
{
// 1. 创建打开图片的对话框
var imageFileDialog = new OpenFileDialog();
// 2. 设置对话框能够打开图片类型
imageFileDialog.Filter = "图片|*.jpg;*.png";
// 3. 设置默认打开图片扩展名称
imageFileDialog.DefaultExt = ".png";
// 4. 打开判断对话框是否打开
if (imageFileDialog.ShowDialog() == true)
{

// 5. 获取选择的图片名称
var fileName = imageFileDialog.FileName;
// 6. 创建Halcon图片对象
var image = new HImage();
// 7. 把打开图片文件读取到HImage对象中
image.ReadImage(fileName);
// 8. 清空控件上显示图片
Hsmart.HalconWindow.ClearWindow();
// 9. 使用Halcon控件显示图片
Hsmart.HalconWindow.DispObj(image);
}
}
}
}

三、HWindowControlWPF与HSmartWindowControlWPF区别

HWindowControlWPF是Halcon提供的WPF控件，用于显示Halcon图像，而HSmartWindowControlWPF是Halcon提供的高级WPF控件，除了能显示Halcon图像外，还可以进行交互式图像处理和测量等操作。HSmartWindowControlWPF还可以添加自定义的工具栏和菜单，使用户能够更方便地进行图像处理。因此，HSmartWindowControlWPF相比HWindowControlWPF具有更多的功能和灵活性。

1、添加加载图片按钮和方法

using HalconDotNet;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace _3_SmartAndHWDemo
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}

/// <summary>
/// 加载HWindowControlWPF控件的图片
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Btn_LoadHWImage_Click(object sender, RoutedEventArgs e)
{
int width, height;
var image = new HImage();
image.ReadImage("E:\\NetProjects\\测试项目\\Halcon\\源码及素材\\2\\image.png");
image.GetImageSize(out width, out height);
HW.HalconWindow.SetPart(0,0, width, height);
HW.HalconWindow.DispObj(image);
HW.SetFullImagePart(image);
}

/// <summary>
/// 加载HSmartWindowControlWPF控件的图片
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Btn_LoadHSImage_Click(object sender, RoutedEventArgs e)
{
var image = new HImage();
image.ReadImage("E:\\NetProjects\\测试项目\\Halcon\\源码及素材\\2\\image.png");
HS.HalconWindow.DispObj(image);
HS.SetFullImagePart();
}
/// <summary>
/// 绘制矩形
/// </summary>
List<HDrawingObject> hDrawingObjects = new List<HDrawingObject>();
private void Btn_Rect_click(object sender, RoutedEventArgs e)
{
var hdrawObj = HDrawingObject.CreateDrawingObject(HDrawingObject.HDrawingObjectType.RECTANGLE1, new HTuple[] { 100, 100, 150, 250 });
hDrawingObjects.Add(hdrawObj);
HW.HalconWindow.AttachDrawingObjectToWindow(hdrawObj);
}
}
}

四、绘制ROI区域并展示模板匹配的结果

using HalconDotNet;

public partial class ModelService
{
public ModelService()
{
// Default settings used in HDevelop
HOperatorSet.SetSystem("width", 512);
HOperatorSet.SetSystem("height", 512);
if (HalconAPI.isWindows)
HOperatorSet.SetSystem("use_window_thread", "true");
}

public void ExcuteModel(HTuple hv_WindowHandle, HObject ho_image, HTuple hv_ModelID)
{

try
{

//检索图片上根据模板匹配图像

, (new HTuple(360)).TupleRad(), 0.9, 1.1, 0.5, 1, 0.5, "least_squares",
0, 0.9, out hv_Row1, out hv_Column1, out hv_Angle, out hv_Scale, out hv_Score);
//// 显示匹配结果
//dev_display_shape_matching_results(hv_ModelID, "orange", hv_Row1, hv_Column1,
// hv_Angle, 1, 1, 0);
//// 设置现在字体和大小
//set_display_font(hv_WindowHandle, 26, "mono", "true", "false");
//// 窗口上显示匹配坐标
//disp_message(hv_WindowHandle, (("匹配坐标:" + hv_Row1) + new HTuple(",")) + hv_Column1,
// "window", 20, 20, "black", "true");
// 设置显示颜色
HOperatorSet.SetColor(hv_WindowHandle, new HTuple("green"));
// 生成十字准星
HOperatorSet.DispCross(hv_WindowHandle, hv_Row1, hv_Column1, 150, hv_Angle);
}
catch (HalconException HDevExpDefaultException)

// If set to 'image', image coordinates are used.
// (This may be useful in zoomed images.)
//Row: The row coordinate of the desired text position.
// You can pass a single value or a tuple of values.
// See the explanation below.
// Default: 12.
//Column: The column coordinate of the desired text position.
// You can pass a single value or a tuple of values.

// -- color string: A box is displayed in the given color, e.g., 'white', '#FF00CC'.
// - Box[1] (Optional): Controls the shadow of the box. Possible values:
// -- 'true' (Default): A shadow is displayed in
// darker orange if Box[0] is not a color and in 'white' otherwise.
// -- 'false': No shadow is displayed.
// -- color string: A shadow is displayed in the given color, e.g., 'white', '#FF00CC'.

// - |Row| == n, |Column| == n
// - |Row| == n, |Column| == 1
// - |Row| == 1, |Column| == n
// In this case we distinguish:
// - |String| == n: Each element of String is displayed

// - |String| == 1: String is displayed n times
// at the corresponding positions.
// - Exactly one text position is specified,
// i.e., |Row| == |Column| == 1:
// Each element of String is display in a new textline.
