效果展示

一、题目要求

求出最大值，最小值，平均值

二、分析

1.首先要进行模板匹配

2.划清匹配范围

3.匹配小三角的模板匹配

4.卡尺

5.用找圆工具

工具

1.CogPMAlignTool

2.CogCaliperTool

3.CogFindCircleTool

4.CogFixtureTool

三、模板匹配工具

1.搜索区域

2.齿轮匹配

3.设置参数

4.卡尺设置

5.找圆工具

四、代码分析

1.声明集合，文字显示工具，线段

 CogGraphicCollection dt = new CogGraphicCollection();
  CogGraphicLabel label;
  CogLineSegment line;

2.将工具进行实例化

 dt.Clear();
    CogPMAlignTool pma = mToolBlock.Tools["CogPMAlignTool2"]as CogPMAlignTool;
    CogCaliperTool caliper = mToolBlock.Tools["CogCaliperTool1"]as CogCaliperTool;
    CogFindCircleTool find = mToolBlock.Tools["CogFindCircleTool1"]as CogFindCircleTool;

3.解决实例化问题

4.声明List 弧度转角度（角度转弧度）遍历卡尺数量

公式：弧度=角度/180*Math.PI

角度=弧度*180/MathPI

 List<double> distance = new List<double>();


 for(int i = 0;i < pma.Results.Count;i++)
    {
      double angle = pma.Results[i].GetPose().Rotation * 180 / Math.PI;
      double rad = (angle - 90) / 180 * Math.PI;
      
      caliper.Region.CenterX = pma.Results[i].GetPose().TranslationX;
      caliper.Region.CenterY = pma.Results[i].GetPose().TranslationY;
      caliper.Region.Rotation = rad;
      caliper.Run();

5.卡尺找到的地方声明线段

 line = new CogLineSegment();
      line.SetStartEnd(find.Results.GetCircle().CenterX, find.Results.GetCircle().CenterY, caliper.Results[0].Edge0.PositionX, caliper.Results[0].Edge0.PositionY);
      line.LineWidthInScreenPixels = 1;
      line.Color = CogColorConstants.Red;
      dt.Add(line);

6.实例化点到点的距离工具链接

  CogDistancePointPointTool dis = new CogDistancePointPointTool();
      dis.InputImage = mToolBlock.Inputs["OutputImage"].Value as CogImage8Grey;
      dis.StartX = find.Results.GetCircle().CenterX;
      dis.StartY = find.Results.GetCircle().CenterY;
      dis.EndX = caliper.Results[0].Edge0.PositionX;
      dis.EndY = caliper.Results[0].Edge0.PositionY;
      dis.Run();
      distance.Add(dis.Distance);

7.放置每个角的长度位置

 
      label = new CogGraphicLabel();
      label.Font = new Font("楷体", 8);
      label.Color = CogColorConstants.Purple;
      label.SetXYText(caliper.Results[0].Edge0.PositionX, caliper.Results[0].Edge0.PositionY, dis.Distance.ToString("F2"));
      dt.Add(label);

五、找出最大，最小，平均值

double Max = 0;
    double Small = distance[0];
    double total = 0;
    double average;
    for(int i = 0;i < distance.Count;i++)
    {
      if(distance[i] > Max)
      {
        Max = distance[i];
      }
      if(distance[i] < Small)
      {
        Small = distance[i];
      }
      total += distance[i];
    }
    average = total / distance.Count;
    CogGraphicLabel label1 = new CogGraphicLabel();
    CogGraphicLabel label2 = new CogGraphicLabel();
    CogGraphicLabel label3 = new CogGraphicLabel();
    label1.SetXYText(100, 100, "最大值是:" + Max.ToString("F2"));
    label2.SetXYText(100, 130, "最小值是:" + Small.ToString("F2"));
    label3.SetXYText(100, 160, "平均值是:" + average.ToString("F2"));
    label1.Color = CogColorConstants.Red;
    label1.Font = new Font("楷体", 20);
    label2.Color = CogColorConstants.Red;
    label2.Font = new Font("楷体", 20);
    label3.Color = CogColorConstants.Red;
    label3.Font = new Font("楷体", 20);
    dt.Add(label1);
    dt.Add(label2);
    dt.Add(label3);

六、实现在图片工具图上

foreach(ICogGraphic s in dt)
    {
      mToolBlock.AddGraphicToRunRecord(s, lastRecord, "CogPMAlignTool1.InputImage", "");
    }
