标题: C#联合halcon实现直线查找
一、前言

C#之Winform + Halcon实现图像直线查找功能
1、创建计量模型 HMetrologyModel
2、添加计量对象到线测量
3、设置计量对象参数
4、设置查找参数：边缘阈值、边缘选择、太过方式
5、显示测量点

二、运行效果

三、代码

1.         double r1 = 50.00, c1 = 300.0;
2.         double r2 = 150.0, c2 = 300.0;
3.         double measureLength1 = 10, measureLength2 = 10;
4.         double measureSigma   = 1,  measureThreshold = 10;
5.         HTuple genParamName = new HTuple();
6.         HTuple genParamValue = new HTuple();
7.         //*创建计量模型
8.         HMetrologyModel metrologyHandle =new HMetrologyModel();
9.         //*添加计量对象到线测量()
10.         metrologyHandle.AddMetrologyObjectLineMeasure(r1,c1,r2,c2,
11.         measureLength1, measureLength2, measureSigma, measureThreshold,
12.         genParamName, genParamValue);
13.         //*设置计量对象参数
14.         metrologyHandle.SetMetrologyObjectParam( 0, "measure_length1",100);
15.         metrologyHandle.SetMetrologyObjectParam(0, "measure_length2",20);
16.         metrologyHandle.SetMetrologyObjectParam(0, "measure_distance",10);
17.         //*边缘阈值
18.         metrologyHandle.SetMetrologyObjectParam(0, "measure_threshold",10);
19.         //*边缘选择
20.         metrologyHandle.SetMetrologyObjectParam(0, "measure_select","first");
21.         //*过度方式
22.         metrologyHandle.SetMetrologyObjectParam(0, "measure_transition","positive");
23.         //ho_image为自己创建的HImage对象实例 HImage ho_image = new HImage()
24.         //
25.         metrologyHandle.ApplyMetrologyModel(ho_image);
26.         //*显示测量点
27.         HXLDCont contours = new HXLDCont();
28.         contours = metrologyHandle.GetMetrologyObjectMeasures(0, "all", out HTuple row, out HTuple column);
29.         HXLDCont xldCont = new HXLDCont();
30.         xldCont.GenCrossContourXld(row, column, 10, 0.785398);
31.         HTuple result = metrologyHandle.GetMetrologyObjectResult(0, "all", "result_type",
32.                 new HTuple(new string[] { "row_begin", "column_begin", "row_end", "column_end" }));
33.         //*获得测量直线
34.         double row_begin = result[0];
35.         double column_begin = result[1];
36.         double row_end = result[2];
37.         double column_end = result[3];
38.         HXLDCont xldLine = new HXLDCont();
39.         xldLine.GenContourPolygonXld(
40.         new HTuple(new double[] { row_begin, row_end }),
41.         new HTuple(new double[] { column_begin, column_end })
42.          );
43.         //设置颜色并显示
44.         //自己封装的方法
45.         hWTool.DispObj(contours,"blue");//测量的直线范围
46.         hWTool.DispObj(xldLine, "blue");//测量出来的直线
47.         hWTool.DispObj(xldCont, "green");//测量出来的点
48.         //hWindowControl1为HWindowControl对象实例
49.         //hWindowControl1.HalconWindow.SetColor("blue");
50.         //hWindowControl1.HalconWindow.DispObj(xldLine);//测量出来的直线
51.         //hWindowControl1.HalconWindow.SetColor("red");
52.         //hWindowControl1.HalconWindow.DispObj(contours);//测量的直线范围
53.         // hWindowControl1.HalconWindow.SetColor("green");
54.         //hWindowControl1.HalconWindow.DispObj(xldCont);//测量出来的点
