主要就是c#联合Halcon进行几何定位（也可以叫做模型匹配），本程序主要是基于单模板，进行单个模板的匹配以及循环遍历模板的匹配，如果您觉得文章不错，麻烦您关注博主，如有不对的地方，还希望大家提出来，我们共同进步。
一: 程序配置
1： 首先配置在winfom引用程序中引用两个halcon应用程序的库：分别是halcon.dll和halcondotnet.dll，而后把这两个库放在你的应用程序输出路径下面，然后在下边的图片中取消首选32位的勾选。
2：右键点击工具箱，单击选择项，然后点击浏览按钮，引用halcondotnet.dll控件，点击确定就可以显示HWindowControl控件了
二： 程序界面：
用到的控件分别为：
1个图形窗口HWindowControl，2个ListBox控件，5个button控件
程序界面
三：运行效果展示
1：点击读取图片选择一个图片并画ROI区域,在下边可以看到读取图像成功，并且获得模板的基准。
2：点击图片列表载入可以选择多幅图片并且在右上角的listbox控件中显示多幅图片的路径。
3：选中右上角listbox控件的一个项然后单击单步模型匹配会根据不同方向，位置同一个图像进行几何定位
4：点击遍历查找模型可以快速地对右上角listbox控件中的所有图片进行快熟匹配
四：程序代码
读取模型图片按钮代码：
private void button读取图片_Click(object sender, EventArgs e)
{
HTuple width, height;
OpenFileDialog openFile = new OpenFileDialog();
openFile.Filter = "jpg文件(*.jpg)|*.jpg|png文件(*.png)|*.png|bmp文件(*.bmp文件)|*.bmp";
if (openFile.ShowDialog()==DialogResult.OK)
{
hImage.ReadImage(openFile.FileName);
//设置读取的图片的大小，并且刚好设置在窗口中
HOperatorSet.GetImageSize(hImage, out width, out height);
HOperatorSet.SetPart(hw1.HalconWindow, 0, 0, height, width);
//图像显示
hImage.DispObj(hw1.HalconWindow);
listBox信息.Items.Add("读取单个图像成功");
}
}画ROI按钮：
private void button画ROI_Click(object sender, EventArgs e)
{
try
{
//取消焦点
hw1.Focus();
HOperatorSet.SetColor(hw1.HalconWindow, "red");
HOperatorSet.DrawRectangle2(hw1.HalconID, out row, out column, out phi, out length1, out length);
HOperatorSet.GenRectangle2(out rectangle2, row, column, phi, length1, length);
HOperatorSet.DispObj(rectangle2, hw1.HalconID);
HOperatorSet.ReduceDomain(hImage, rectangle2, out ho_ImageReduced);
HOperatorSet.CreateShapeModel(ho_ImageReduced, "auto", (new HTuple(-180)).TupleRad()
, (new HTuple(360)).TupleRad(), "auto", "auto", "use_polarity", "auto", "auto",
out modelId);
HOperatorSet.FindShapeModel(hImage, modelId, (new HTuple(-180)).TupleRad()
, (new HTuple(360)).TupleRad(), 0.5, 1, 0.5, "least_squares", 0, 0.9, out hv_Row1,
out hv_Column1, out hv_Angle, out hv_Score);
//显示匹配结果
dev_display_shape_matching_results(modelId, "red", hv_Row1, hv_Column1, hv_Angle,
1, 1, 0);
//产生十字交叉点
HOperatorSet.GenCrossContourXld(out ho_Cross, hv_Row1, hv_Column1, 15, (new HTuple(-45)).TupleRad());
HOperatorSet.DispObj(ho_Cross, hw1.HalconWindow);
listBox信息.Items.Add("画模板ROI区域成功");
listBox信息.Items.Add("获得基准模板成功");
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
}图片列表载入按钮：
private void button图片载入_Click(object sender, EventArgs e)
{
//多个图片的载入
OpenFileDialog openFile = new OpenFileDialog();
//设置打开属性Multiselect为true表示允许选中多个图片文件
openFile.Multiselect = true;
openFile.Filter = "JPG文件|*.jpg|PNG文件|*.png|BMP文件|*.bmp";
if (openFile.ShowDialog()==DialogResult.OK)
{
foreach (var item in openFile.FileNames)
{
listBox文件.Items.Add(item);
}
}
}单步查找模型按钮：
private void button单模型查找_Click(object sender, EventArgs e)
{
HImage hImagetwo = new HImage();
string a = Convert.ToString(listBox文件.SelectedItem);
hImagetwo.ReadImage(a);
HTuple Width, Height;
//设置图片以合适的方式显示在图片控件上面
HOperatorSet.GetImageSize(hImagetwo, out Width, out Height);
HOperatorSet.SetPart(hw1.HalconWindow, 0, 0, Height, Width);
HOperatorSet.DispObj(hImagetwo, hw1.HalconWindow);
HOperatorSet.FindShapeModel(hImagetwo, modelId, (new HTuple(-180)).TupleRad()
, (new HTuple(360)).TupleRad(), 0.3, 1, 0.5, "least_squares", 0, 0.7, out hv_Row1,
out hv_Column1, out hv_Angle, out hv_Score);
//显示匹配结果
dev_display_shape_matching_results(modelId, "red", hv_Row1, hv_Column1, hv_Angle,
1, 1, 0);
//产生十字交叉点
HOperatorSet.GenCrossContourXld(out ho_Cross, hv_Row1, hv_Column1, 15, (new HTuple(-45)).TupleRad());
HOperatorSet.DispObj(ho_Cross, hw1.HalconWindow);
listBox信息.Items.Add("单个匹配图像成功");
}
遍历查找模型按钮：
private void button循环遍历查找_Click(object sender, EventArgs e)
{
HImage hImagethree = new HImage();
for (int i = 0; i < listBox文件.Items.Count; i++)
{
int index = listBox文件.FindString(Convert.ToString(listBox文件.Items[i]));
if (index != ListBox.NoMatches)
{
listBox文件.SetSelected(index, true); //表示在listbox文件框中当前循环遍历的是哪一个
string filename = Convert.ToString(listBox文件.SelectedItem);
hImagethree.ReadImage(filename);
HTuple Width, Height;
//设置图片以合适的方式显示在图片控件上面
HOperatorSet.GetImageSize(hImagethree, out Width, out Height);
HOperatorSet.SetPart(hw1.HalconWindow, 0, 0, Height, Width);
HOperatorSet.DispObj(hImagethree, hw1.HalconWindow);
HOperatorSet.FindShapeModel(hImagethree, modelId, (new HTuple(-180)).TupleRad()
, (new HTuple(360)).TupleRad(), 0.3, 1, 0.5, "least_squares", 0, 0.7, out hv_Row1,
out hv_Column1, out hv_Angle, out hv_Score);
//显示匹配结果
if (hv_Row1>0&&hv_Column1>0)
{
//显示匹配结果
dev_display_shape_matching_results(modelId, "red", hv_Row1, hv_Column1, hv_Angle,
1, 1, 0);
//产生十字交叉点
HOperatorSet.GenCrossContourXld(out ho_Cross, hv_Row1, hv_Column1, 15, (new HTuple(-45)).TupleRad());
HOperatorSet.DispObj(ho_Cross, hw1.HalconWindow);
listBox信息.Items.Add("循环遍历中匹配单个图像成功");
}
}
